　　Residue problem of protective film does not know how many manufacturers use a headache how many times, each time leaving residue, resulting in an extremely bad influence on the products, to solve the problem of residue PE protective film, the key is to choose the protective film varieties, so the selection of protective film protective film, multi scale complete, stable supply manufacturers, is very necessary.

　　A general problem of main reason degumming PE protective film product is when a user profile to be installed after the completion of the construction must take the PE protective film torn from the surface to the profile, but also continue to carry out a viscose protective film performance and not with the protective film, but residues in a section on the product.

　　This is the last thing a user would like to see. A pressure rubber product is probably the protective film used generally is not in conformity with the provisions, but also is more viscous, this will lead to protection film product is stripped, when the tension is greater than a situation in the resistance, and the residue in the section on.

　　The general causes of PE protective film no way effectively stripped there are generally two kinds of possibilities, one is the PE protection film products for sensitive adhesive and protective film is not a special sensitive glue, however the protective film in the paste when the effect is very good, but in general the comparison will peel difficult, protective film which is also some illegal protection film products manufacturers produced a most frequently a problem.

　　There is a possibility that the PE protective film with a parent material is used, of course, is not a force to bear upon peeling fracture phenomenon, thus appear when peeled, generally this is a problem that the user is a headache.

PET silicone protective film, why are bubbles open and warped phenomenon?

/0 Comments/in , , , /by

PET protective film is a kind of material with smooth surface and good electric insulation. It doesn’t adhere to other material. Most of the market saw is a protective film adhesive, so the viscosity can often is the use of PET protective film of silicone glue, it is paste glue with high viscosity (KL-2634ABC), medium viscosity (KL-2620ABC), low viscosity (KL-2620ABC) of three kinds of silicone glue, are high temperature adhesive. The viscosity here is also known as the peel rate, and G can be used to indicate his viscosity.

Low viscosity refers to the peeling rate of 1-3g, medium viscosity refers to the peeling rate of 3-5g, high viscosity refers to the peeling rate of 10-100G, and the adhesive has a good flow support before curing. After curing, the exhaust and transparency are also very high. So it is widely used in computer monitors, protective screen, and mobile phone protection towels and other PET silicone protective film.

The question of bubbles is not related to the rate of peeling off. Usually in production operations, some places do not notice, for example:

The ratio of solvent to dilute 1. please A:B:C: solvent =100:100:10:400, solvent can be used here water containing low toluene or ethyl acetate to mix better, this is more conducive to dilute the PET protective film of the silicone glue paste (to prevent brushing due to the uneven mixing and foaming), according to the order to add glue the first B (delay agent) and C (tackifier) mixed evenly, and then adding A material (catalyst) mixing time is 20 minutes.

2. knife roller coating method by scraping or evenly brush on the PET film, PET film clean, prior to use alcohol liquid to clean the PET film, to ensure that no stains protective film, and spraying when touching it, please bring clean gloves to prevent hand perspiration or dirt contact the PET film, resulting in uneven brushing, foaming phenomenon.

3. into the oven or tunnel oven curing, the curing is best to use a gradual approach, the oven temperature is set to 90 C to 160 C to 100 C, barbecue time according to the amount of coating to adjust, when the dry gel thickness in 10 m coating, glue the barbecue time control in 1 minutes. Dry glue thickness in 20 m coating, glue baking time should be controlled within 1 minutes, pay special attention to the baking time should not be too long or too short, the accuracy of baking time is a protective film two warped decision, or bubble reason

How is the transparency of the PE protective film controlled?

PE protective film about the transparency of products meet the quality, is here to protect the membrane manufacturers Kai membrane to introduce you is how to promote the transparency of PE protective film:

1.PE protective film is a crystalline material which is easy to crystallize. If it is not cooled rapidly, it will decrease the transparency and elongation at break. The cooling effect of blow molding is poor, the crystallinity is high, and the film transparency is low.

2., due to blow up and drawing, the molecular orientation is serious, resulting in low elongation at break, while the casting has good cooling effect, low crystallinity, good transparency and low orientation, so the elongation at break is high and the shrinkage is good.

3. need to add some anti fog agent.

4. on the basis of the above, add transparent nucleating agent.

5.PE protective film material selection, choose low fog, high melting fingers.

Now the protective film material is some very good material, so for these protective film is also very convenient. The screen protective film now have their own a big sky, for which you have to learn some very little understanding of their own and some great understanding of it, now a protective film for these methods only stay in order to learn more things. What are the uses of protective membranes, respectively? You have to know about this. Now, there are many people who don’t know much about the protective membrane, so these are the things you have to do. There are some things you need to know about the protective membrane, such as how to analyze some of the material that protects the film, which you also need to know and understand.

There are two kinds of protective films: one is oil free adhesive paper; the other is water glue with off base paper. The above two are composed of three parts: from the paper, glue coated on silicon (rubber oil or water glue), PVC plastic film. Film type oil glue composite, due to different purposes is generally not known protective film (also for protection), mainly used for advertising, such as a computer, its oil glue function is carving characters and patterns is not easy deformation, suitable for long-term paste is not easy to fall off, alice. Such products, such as instant stickers, furniture stickers, stickers and so on. Protective film is a composite protective film of water and glue. It is mainly used for engraving art, glass and surface protection of other things. Water gel, that is, Armin glue series, this gum non-toxic, harmless to the human body, is in line with state regulations green environmental protection glue.

Introduction to protective film applications:

The protective film according to the scope of application, can be used in the following areas: the surface of metal products, metal products, plastic products surface coating surface, automotive products surface, the surface of the electronic product, product surface, the surface profile of the product label, and other products surface.

The biggest advantage of protective film:

The protected products are free from pollution, corrosion and scratches during the process of production, processing, transportation, storage and use, and protect the original bright and clean surface so as to improve the quality of the products and the market competitiveness.

How to buy protective films need to pay attention to what?

Shopping is the main course of the quality, price and customer service service three, there is no exception in the film industry, quality is the key, which requires the buyer must have an understanding of their own use of the products, so as to be an antidote against the disease. Secondly, the price, protective film is mainly used in product packaging, cost savings is to see how to spend the least amount of money to buy the best goods. Finally, customer service service, the use of protective film is quite a long time, manufacturers generally use a month’s order is not a few, so the protective film supplier customer service service is an important factor for buyers to consider.

To prevent some dealers from their own interests, recommend some counterfeit and shoddy goods to consumers.

How to choose when you buy?

In the purchase of protective membrane products, should pay attention to the following

1., we should select high protection, stable quality, good after-sales service of protective film products.

2. check the purchase of the product packaging logo, logo is complete (executive standard, grade, manufacturer name, address, date of production including product packaging) is solid, specification and product compliance, beware of exaggerated and the phenomenon is inconsistent with the facts.

3. to observe the appearance of the protective film quality, including color, transparency, viscosity, and whether there are crystal dots and holes in the protective film.

4. check the protective film function is reliable, flexible and should choose more than two products were examined, in the test, two or more products to choose the corresponding comparison test, to find a meeting point with their own products.

5. after the test, it is necessary to estimate the service life of the protective film. If it is a temporary protective film, see whether the protective film is left with residual glue after it is torn off.
