1. The cleanliness of release membranes is currently an important factor that restricts the widespread use of high-quality fluorine release membranes in HDI production; Therefore, manufacturers or suppliers of durable fluorine release films must operate in clean rooms when coating, winding, and cutting release films. The clean room must reach a level of 10000 to ensure the surface cleanliness of the release film, thereby ensuring the quality of the RCC pressed board. 2. Pay attention to distinguishing between the front and back sides of the single sided release film. As the single sided fluorine release film only has one side for release and the other side is the PET substrate surface, if the release film is used on the wrong side, it will cause the film to stick to the plate when pressing it down

Release film is very important for certain products, and its quality will directly affect its function. Therefore, when choosing release film, we should also recognize its quality. It is best to be safe and to test the quality of the UV lamp release film to ensure everything is correct. Next, please continue to follow the editor from the polarizer release film manufacturer of Dingli Company to take a look. Due to the unique structure of the release film, the quality inspection of the high-pressure spray gun release film can start with the thickness inspection of the PVC release film, as it is related to the impact force of the release film. Generally speaking, the thickness of this layer of mask should be around 9 wires to ensure product protection

Do you know the differences between fluorine release film and coating film? If you don't know, follow the editor of Ruichangxing Technology to learn more! 1、 Coating film: In order to improve the surface performance of PET film, improve printing adaptability, and enhance the adhesion of vacuum aluminum coating, corona treatment is usually used to increase the surface tension of the film. However, the corona method has issues with timeliness, especially in high temperature and humidity environments where the film tension after corona treatment is easily attenuated. However, the chemical coating method does not have such a problem, so it is favored by the printing and aluminum plating industries. Currently, a PET chemical coating system has been developed in China

The purpose and quality requirements of PET release film. PET release film is a commonly used material for heat transfer printing, and the substrate is PET, which is coated with silicone oil and is also called silicone oil film. The characteristic of PET reflective film is that it has excellent optical properties, smooth and clean surface, good thermal stability, low shrinkage rate, and light aging resistance. With the development of market demand, the demand for PET film and PET release film in industrial production is increasing. There are more and more domestic companies producing PET films and PET release films, followed by a transparent market situation. I won't say much about PET film here, after all, it's not a special requirement for use,

How to distinguish the quality of fiberglass cloth? It is based on glass fiber woven fabric, soaked with macromolecule anti lotion coating, and is widely used in wall reinforcement materials, reinforced cement products, reinforced plastics, rubber products, and other skeleton materials. Many friends are using it, but how to distinguish between good and bad? Today, the editor will share with you how to distinguish between good and bad. Method 1: Determine the quality of fiberglass cloth by observing its surface. The quality is relatively good, the surface is relatively clean, the warp and weft lines of the grid are uniform and straight, the toughness is good, and the mesh holes are also relatively uniform. And those with poor quality have uneven grids and poor toughness.

It is understood that most release film manufacturers in the current market choose fluorine release film as the bottom film for curved hot bending film, and of course, a small number of manufacturers also choose non silicon release film. Fluorine release film, based on leading technologies in its release, fluorine chemistry, optics, microstructure surface, precision coating, etc., has a flat and smooth surface, uniform coating, and no defects such as wrinkles, tears, particles, bubbles, etc. From this, it can be seen that fluorine release film will become the best choice for curved hot bending film bottom film. Whether it is fluorine release membrane or non silicon release membrane, the purpose of selection is to solve the problem of release matching. However, selecting a suitable base film to fit this super

After years of experience from Shenzhen release film manufacturers, the problems encountered in work have been summarized, and several precautions for selecting pressure sensitive adhesive materials correctly and effectively improving touch quality have been proposed. 1、 Do not use a die-cutting board made of die-cutting paper material, as the blade is worn and not suitable for die-cutting film. 2、 When flat pressing and cutting, try to reduce the die-cutting area as much as possible, especially for full size small labels, as the layout is large, there are many knife arrangements, and the quality is difficult to guarantee. 3、 When cutting flat dies, it is necessary to frequently replace the pad plate, especially when processing long plates, as cutting can affect the quality of the new label's die-cutting. 4、 When flat pressing and die-cutting, the die-cutting force should be just right, this is the blue release film

Many users do not have much understanding of PET release films, and they often encounter various problems when purchasing release films. Are release films and film products the same? Today, as a professional manufacturer of PET release film, I will talk to you. When purchasing release films, users should note that there is a certain difference between this type of film and ordinary film products. Film products do not have any adhesive coating on them, so when touching the surface of the film with their hands, there will be no viscosity. Release films and film products have differences in production technology and feel. When making PET release films, PET will be used as the original

PE protective film for automobiles plays a great role in our daily life and industrial production. Our phones, computers, and monitors all rely on protective film protection. So what is the lifespan of the PE protective film applied to the car? As is well known, a good car protective film is usually used normally for 5 to 6 years, but the premise is to maintain it well. If the precautions for car protective film are not clear, the service life of the car protective film will be greatly reduced, which is inevitable. 1. Do not lift the glass within a week. Generally speaking, it takes 5-7 days for the car protective film to firmly adhere to the window. During this period,

For silicone gaskets, they can be used in different scenarios, and different scenarios require silicone gaskets to play different roles. At this point, we need to choose the appropriate silicone gasket according to the requirements of different scenarios. Let's learn about the classification of silicone gaskets and the applicable scenarios together. 1. Thermal conductive silica gel pad Thermal conductive silica gel sheet is a kind of thermal conductive medium material synthesized by a special process with silica gel as the base material and various auxiliary materials such as metal oxides. In the industry, it is also called thermal conductive silica gel pad, thermal conductive silicone film, soft Thermally conductive pad, thermal conductive silica gel pad, etc. Control motherboard for electronic and electrical products, as well as internal and external pads for motors

Silicone gaskets are widely used in electronic products. The main function of silicone gaskets is to use gaps for heat transfer, playing a role in insulation, shock absorption, and sealing. However, due to improper usage, some customers did not achieve the desired results and instead damaged the silicone pad. What should be noted when using silicone pads? Firstly, the silicone pad surface should be kept clean to avoid sticking to dirt, resulting in poor self-adhesion and sealing thermal conductivity. Secondly, when taking a large area of thermal conductive silicone gasket, it should be taken from the center, as the uneven force on the large silicone gasket can cause deformation and affect subsequent operations. Thirdly, when using, take the tablet with the left hand and tear off a protective film with the right hand. Don't be the same

PET release film plays an important role in the production of double-sided tape. If die cutting double-sided tape requires release film, the key characteristics of release film are coating uniformity, high residual adhesion, flatness and high cleanliness. What should be paid attention to when using transparent pet release film? 1. High residual adhesion: the residual adhesion should be affected by silicone oil formula, coating conditions and substrate treatment, The technical services of silicone oil factories also need to be strengthened. 2. Coating uniformity: The release film should be evenly coated. In addition to selecting appropriate solvents, controlling the concentration, viscosity, and solvent evaporation time of the coating agent, the coating equipment is crucial
