Plastic bag making machine problem solution in Dubai,Ajman,Umm al-Quwain,Abu Dhabi,Sharjah,Fujairah,United Arab Emirates 

Plastic Bag Machine is the final step in the manufacturing and processing of plastic bag. If the performance of bag making process isn’t high enough or the quantity of waste is excessive, the previous processes , such as blowing film machine or composite printing machine could end up being used up and downstream customers are likely to have an enormous effects on the manufacturing and operations.

1. What can I do if my bag’s contents leak or become damaged because of the insufficient sealant of the plastic bag machine?
Cause: Low anti-pollution heat-sealability for the film, mostly due to the resin that is used in the sealing layer isn’t suitable for.
Countermeasures: Select a film that has excellent anti-pollution heat-sealability. The general rule is that ldpe has moderate anti-pollution heating capacity. EVA is a good anti-pollution heat sealability in the event that the VA contents are large. Ionic resin and metallocene-based polymer It is extremely effective in preventing pollution heat-sealability.

2.What can I do when the seal of the plastic bag machine isn’t as strong?

Reasons:

1. The temperature of heat sealing is excessively high.
2. The pressure is too high.
3. The time to seal heat is too long.
4. Edge of upper section of the sealer sharp or the PTFE coating is damaged.
5. The seal on the bottom is Silicone rubber that is too for the job;
6, in the process of compounding and curing during the curing and compounding process, a portion of the adhesive gets absorbed into the film. When the substrate is impacted by the adhesive. As a result, the hardness (that is, resistance to impact) has diminished and the brittleness grown;
7 Plastic composite baggies for packing Following cooling and putting in place the bags, the durability of the heat seal improves and the bag also begins to harden.

Countermeasures:

1. Based on the heat sealing properties of the outer sealing layer material, choose the right temperatures, pressure, and time to seal the heat;

2. Improve the surface quality of the top heat sealing knife so that it makes the sealer’s surface smooth;

3. Wrap the cloth with polyethylene. The wrapping is still intact.

4. Select a pad made of silicone that is of the right degree of hardness.

What can I do if my bag starts to shrink after being sealant by the bag maker?
The reason:
1. The film’s thickness is variable;
2. The temperature for heat sealing is too high, or the time to seal can be too lengthy.
3. In the heat sealing knife’s longitudinal section The running path of composite films isn’t straight.
4. Insufficient cooling.
5. The time for curing isn’t enough.
6. The film on the surface is not very resistant to heat.
7. Inadequate control of the tension-matching to the substrate of the composite during the process of compounding causes residual stress following curing and setting, particularly in cases where the composite film is smaller this type of failure is more likely to occur.
Countermeasure
1. The tension can be adjusted on the roller floating.
2. Utilize an inner sealing base material that has low temperature heat sealability.
3. Adjust the temperature of the heat seal to the appropriate temperature.
4. It is important to cool down.
5. Create a film that is mature.
6. Re-select the film on the surface.
7. Adjust the tension on each component of the composite processing equipment, and then try to ensure that both substrates shrink the same.

What can I do if I notice that the outer shape of the heat-sealed exterior of the bag-making machine isn’t clear after sealing? (The knife’s pattern isn’t evident)
The reason is:
1. The cooling process is short.
2. The cooling plate is not in good contact with the plate
3. When the pad of silicone is heated, the edges melt.
4. Forces of heat sealing in the longitudinal direction that are not balanced
5. Its edge on the heat sealing knife is sloping and blunt.
Countermeasure
1. Set the cooling time.
2. Adjust the cooling plate to your liking.
3. Adjust or replace the knife that seals heat
4. Avoid melting at the edge due to overheating of the silicon pad.

What can I do if the sealing capacity of the bag maker is weak after sealing?
the reasonfor this:
1. The adhesive contained in the composite film hasn’t been properly cured.
2. The conditions for heat sealing are not appropriate.
3. Between the knife that seals the temperature and the cooling knife is too long.
4. There is an issue with the inner layer of sealing.
5. The ink’s heat-sealability is weak, resulting in a reduction in the strength of composites of the film in the sealed part.
6. Dust and spray powders as well as other substances stick on the cover.
7. The strength of the composite is not high or the strength of the heat sealed place decreases too much.

Countermeasures:
1. Help to promote the hardening process of adhesive (curing or curing) by preserving heat and aging. This will improve the strength and resistance to heat of the film.
2. Find the ideal conditions for heat-sealing (temperature as well as time and pressure) in accordance with the structure of the material, its heat-sealing state and so on. Or, you can enhance the method of heat-sealing, and then cool down right away after the heat-sealing process.
3. Examine the shelf time and storage conditions of the film that is heat-sealable. If the film is made of the film from the previous batch and also the film has been sealed with heat requires special attention, it is recommended to do so.
4. The thickness of the film that can be heat-sealable.
5. Modify the type and the grade of the film that can be heat-sealable and choose a film that has anti-pollution heat-sealability.
6. Verify that the quality of the adhesive meets standards (the release of low-molecular substances in the resin can alter how the glue is made)
7. Improve the heat sealing efficiency in the layers of heat. regulate the contents of the slip agents and utilize the mlldpe film.
8. Monitor the monomer concentration in MDI within the composite adhesive.

What can I do if the formation of air bubbles, or uneven surface are found in the heat-sealed area of the bag-making machine?
The reason:
1. When heat-sealing is applied to an object made up of hygroscopic material like nylon film the hygroscopic film can create air bubbles after it is absorbed by moisture.
2. The heat-sealing blade or pad of silicone is not even.
3. Insufficient pressure for heat sealing.
4. One-component adhesives, like neoprene adhesives when sealing bags with heat are used, the heat cover can be prone to pits.
Countermeasures:
1. Make sure to store the semi-finished and raw materials in a proper manner to prevent the absorption of moisture.
2. Make sure to adjust or test or adjust the knife for heat sealing as needed and the heat sealing pad.
3. Remove the tape.

The living room tile wall decoration design can be described as various, because the tile itself is a very rich decorative material, whether it is style, color or material composition, it is easy for the owners to pick the eye, but the industry the Lord can slowly pick out the final goal as long as he knows his final goal.

Stone Displays Tower Natural Stone Sample Rack Stand SW21,we supply stone display tower,natural stone display rack,stone display stand,etc. If the living room area exceeds 30 square meters, 80*80 bricks should be selected, which is less than this area, below 60*60, but not less than 40*40. The large size makes the room spacious and open.

However, if the large-size tile is laid on a small floor, it will make the size of the room uncoordinated, just like a thin person wearing a large dress. On the contrary, if a large area of the floor is covered with small-sized tiles, it will appear as a room. Congestion inside is cumbersome. In short, shoes that fit the size of their feet are good shoes.

The indoor requirements are spacious and bright, making people feel relaxed and quiet. Therefore, the general light-colored tile paving is suitable, such as white, light beige, solid or slightly striped, for the owner with high hygiene requirements, choose pure Color can better reflect the elegance of the owner, but it takes more time and spirit, because the solid color is not dirty, it needs to be cleaned frequently, and it is busy for some work and willing to spend free time sleeping.

Secondly, the material is better. It is better to choose glass fossils because it is wear-resistant, bright and easy to clean. Some people also like to use antique bricks, antique bricks are rich in color, reflecting individuality, but the color is often heavy, and washing has certain difficulty. Stone It is best not to use, because not only the stone cost is high, the color is single, and the stone is mostly radioactive, and the surface roughness and wear resistance are also low. They are often used in large public areas. Pavement method for living room interior wall tiles

1. Leveling: Before laying the tiles, the wall surface of the paved building should be treated to remove the surface dirt, and the water is wet, then mix and level with cement mortar, and the flat layer should be completely dry and then laid.

2. When arranging the tiles, the ash seam of 2mm-3Mm should be reserved between the tiles according to actual needs, in order to prevent the thermal expansion and contraction coefficient between the wall and the tiles and the bond from appearing. , the phenomenon of empty drums, etc., resulting in construction quality Therefore.

3. the elastic line: According to the design and paving requirements, determine the brick layout plan, the ceramic tile position and the brick seam position line are popped on the dry screed layer.

Advantages and disadvantages of living room wall tiling If you use it to decorate it, it will make your grades look a lot better, and there are a lot of graphics to choose from. You can also choose the tile background wall according to your favorite style, for example, local style, Europe Beautiful style, non-mainstream style and more. You can also make your favorite picture into the background wall you want. Tsianfan displays https://www.stonestand.com/

Because the production process is to bake or engrave the pattern on the tile, and finally get the color, so the visual is a big enjoyment, basically the color will not change, the moisture-proof, etc. will not be used like a wallpaper. how long It is wet. The price is not cheap, and it may sell hundreds or even thousands of dollars in some stores on the ground. The price on the Internet will be much cheaper.Plus is custom, so it usually takes 10 days to buy to see your tile wall after purchase.

Film Blowing Machine Troubleshooting

The growing demand for global processors to keep their blown film machine(also called film blowing machine) operations operating as efficiently as they can. Making multi-layer and single layer blown films that have excellent uniformity of the film, strong tensile strength and robust barrier properties, leaves no space for errors. To ensure product consistency as well as a low amount of waste and decreased downtime, we’ve compiled some of the most frequent blow-film issues and ways to resolve these issues.

Problem:Gels, un-melts, Charred polymer
Reason: Overheated/degraded polymer, poor melting, foreign substances in the resin stream
Troubleshooting:

• • Reduce the melting temperature or, if it does not melt then increase the extruder barrel temperature
  • Make sure you have a thermocouple installed and that you are able to make sure that the heater is controlled correctly.
  • Extruder screw damaged or worn out Inspect and take measurements of the screw’s dimensions
  • Damaged or worn out extruder barrel Check and measure the barrel ID
  • Examine the material handling and resins for foreign contamination such as angel hair, fluff and more.

Problem:Melt fracture “Sharkskin”
Cause: Melt temperature too low or die gap too narrow
Troubleshooting:

• • Raise melt temperature (if possible)
  • Raise die lip temperature
  • Activate die lip heaters if quipped
  • Increase die gap
  • As as a last resort, think about the addition of the PPA (polymer processor additive)

Problem:Poor or non-uniform optical clarity
Cause: Inadequate extrudate quenching
Troubleshooting:

• • The melting temperature of the extrudate could be too low. increase the temperature of melt.
  • Non-uniform heating of dies; test thermocouples and heaters
  • IBC Air leaks be sure IBC intake and exhaust pipes are correctly installed
  • The flow of air from the external or internal air ring is not even; ensure to ensure that the ring(s) are aligned. Check for blocked supply lines and dirty coil filters. broken or blocked plenums/screens, dirty or blocked plenums.
  • Interfacial instability caused by co-extrusion; adjust the thickness of the layer using extruder outputs or by substituting a different resin with a different MI.

issue:Voids, “raindrops,” or gray streaks
Cause: Indicates potential moisture in resin stream
Troubleshooting:

• • Determine the source of the moisture problems in the material handling system.
  • Examine the water condensation on the feed section for the extruder (hot humid atmosphere)
  • Check that your raw materials are dry. examine the moisture content using a the heated balance of moisture
  • If dryer is in use to dry clothes, is operating in a proper manner

issue:Milky areas
The reason: Indicates contamination by an incompatible polymer
Troubleshooting:

• • Find out the source of contamination and then eliminate the source of contamination.
  • Clean/purge the materials handling equipment, the hopper and dryer
  • Purge extruder screen changer, purge extruder pipe and die using an un-blended, neat-base resin
  • Clean and disassemble the barrel of extruder as well as feedscrew, filter changer, melting pipe, and die (if required)

Issue:Discoloration
The reason: Indicates the extrudate melt temperature is excessively high.
Troubleshooting:

• • Reduce the temperature of the barrel to the recommended levels

Issue: Poor pigment dispersion
Reason:Indicates poor mixing or uneven melting
Troubleshooting:

• • Residence time inadequate for accurate mixing; increase backpressure/residence time
  • The melting temperature is not sufficient for precise mixing Lower temperature to increase shear
  • Check the blending dosing device for precise and consistent color masterbatch feed
  • Examine the feedscrew’s design and modify or change if needed.
  • Assess the compatibility of the resin’s rheology

Issue: Gauge bands, die lines, film lines
Cause: Indicates contamination at die lips, die adjustment issues, uncontrolled localized tension, non-uniform cooling
Troubleshooting:

• • Die lip is dirty; clean (shim) die lips at localized lines
  • Die is filthy; clean the area, wash and check the die
  • The lip of the die is out of alignment Check the gap of the die and then re-gap
  • Check the air rings on both sides for proper alignment as well as leaks, blockages, and localized high/low velocities and adjust as needed.
  • Check that die is in the center of the bubble cage(s) or frames collapsing are centered. Nip roll is properly centered. that when it is closed the impression of a nip shows the same nipping gap between the chrome and rubber roll
  • Verify that all the transport rollers can are able to rotate freely. Do you notice any tension differences?
  • Eliminate external influences, such as drafts

issue: Wrinkles prior to the rolling of the nip
The reason: A non-uniform extrusion process that begins upstream of the tip
Troubleshooting:

• • Does the bubble breathe? Verify that the extrusion process is stable. The output as well as melt temperature and pressure must be in line
  • Is the bubble still breathing? Examine the frost line; is it consistent and stable? If not, then check the position of IBC sensors to determine whether they are from or above the frost line.
  • Does the air ring appear to be aligned and centered to maintain the stability of the bubble?
  • Are the temperatures of chilled air constant? Check blower stability, chiller temp, cooling coils; look for blocked/crimped/missing supply hoses
  • Are the bubble cages too tight? Examine for bubble breathing. Make sure the cage is properly centered and that it is in good interaction with the balloon. Make sure that the rollers and bubble contact surface are well-maintained and uniform.
  • Is the cage too loose? If it shifts across the room, or makes a an hula-hoop, pull the cage back
  • Does the collapsing frame angle appear too wide? If there are wrinkles on the edges Reduce the collapsing angle.
  • Is the collapsing angle too narrow? If there are wrinkles in the center Increase the collapsing frame angle
  • Are there wrinkles in the lightning bolt? Examine the nip-roll diameter from side-to-side as well as the nip-pressure variations. A lack of even pull from drive rollers with narrow drives or side guides may create wrinkles.

Problem:Film blocking
Reason: Indicates the winding tension or corona treatment levels could be excessively high.
Troubleshooting:

• • Reduce tension of the winding
  • Lessen treatment levels
  • Inadequate film cooling; decrease the temperature of the cooling roll or decrease the speed of the line
  • Inadequate amounts of anti-block additive Increase the effectiveness of anti-block

How To pick out A Power Supply?

Conceptualizing and putting together your dream PC is no straightforward task, however, fortunately getting some fundamentals proper places you in excellent stead for the rest of the build. The best place to begin is the power supply unit, and there’s no better way to choose a PSU than by means of focusing on the features covered in our guide.

Unlike other components, the power supply is not something you need to stint on specifically in case you’ve spent an arm and a leg on a top of the line GPU. Power is overall performance. Let’s dive in.

The Importance Of Wattage

If there’s one overarching rule when it comes to deciding on the right Power supply buy online in UK, it’s ensuring a PSU meets the wattage requirements of your graphics card, processor, and different hardware.

To break it down, each element in a computer requires a certain amount of watts from the power supply to function efficiently. Under-power a machine and it at best struggles and worse won’t even start up. GPUs and CPU are usually the most power-hungry components and consequently go a long manner towards dictating how good deal energy is required.

Fortunately, when it comes to graphics cards and processors, manufacturers often provide the proper amount of power supply wattage as an indicator for what to search for, either in thermal design power (TDP) or maximum energy intake. However, the price is only useful when considered in the context of a pc as a whole. Merely buying a PSU with enough power for your graphics card or processor will cause an underpowered device.

In that sense, it’s well worth making a tally of all the components in a computer and organizing a baseline wattage. You’d be excused for thinking that shopping for a 350 watt PSU for a machine requiring a total of say 345 watts is best. However, in reality, a PSU runs at maximum performance whilst the wattage draw is about 50{d75fa919dee23b6f8e1d22bd4f76e71d5efe3a131614a1ebb9829de444839202} to 80{d75fa919dee23b6f8e1d22bd4f76e71d5efe3a131614a1ebb9829de444839202} of its total output. Power supplies hate an excessive amount of heat, and the high-quality manner to raise the temperature is via gobbling up all its power.

We could, therefore, recommend not pushing the PSU to a 100{d75fa919dee23b6f8e1d22bd4f76e71d5efe3a131614a1ebb9829de444839202} usage under any condition. Once you’ve tallied your wattage needs, the aim for power supply with a wattage output two times as excessive as what’s required. Not most effective will the power supply function better, but it additionally permits some leeway for future upgrades, overclocking, and expansion inclusive of a higher GPU.

The 80PLUS Rating System

In this age of looming climate disaster and growing energy expenses, you can save quite a bit of money by paying a little more for a power supply with a better performance rating than a less expensive competitor. The 80PLUS certification device grades PSUs based on efficiency.

Summary

To summarize, check your wattage needs, get an efficient PSU to save power and money, and make sure you’ve were given the proper cabling and connectors to suit your build.
