What are the techniques that cannot be ignored when purchasing transparent release films? 1. Wear resistance: Liquid crystal film is used to protect the screen, so its own wear resistance must be high. Especially for some handwritten input

We often use various types of glass products in our daily lives, such as glass windows, glasses, glass sliding doors, etc. Glass products balance aesthetics and practicality, making them both adorable with their crystal clear appearance and fully utilizing their hard and durable physical properties. Some art glass even adds more patterns to the glass, enhancing the decorative effect. In this article, we will introduce the use of fiberglass cloth. Types and uses of glass fiber cloth by Shenzhen Ruichangxing Technology Co., Ltd. 1. Medium alkali glass fiber cloth is woven from medium alkali yarn, suitable for making fiberglass base cloth, plastic coating adhesive base cloth, asphalt felt base cloth, and guide

The PET release film is widely used in various industries, not only because the modified product has good adsorption and adhesion, but also because different additives can be added according to different product requirements during production, thus achieving different usage effects. So what are the common types of PET release films with a complete range of categories? 1. Reflective film is a type of release film with excellent optical performance, with a flat and smooth surface, good thermal stability, low shrinkage, and excellent resistance to light aging. Therefore, they are often seen in various transportation facilities and aluminum plated release is used during use

Many times, people fail to choose a high-quality fluorine release film manufacturer, which leads to particularly low quality products and often brings many difficulties when using them. Today, let me share with you, what are the primary standards for choosing fluorine release film manufacturers? There are currently many fluorine release film manufacturers in the market, but their capabilities are indeed mixed. If there are high-quality manufacturers, there will inevitably be poor manufacturers. Only reliable manufacturers can provide greater assurance in product quality, service attitude, and after-sales work, so it is essential to find reliable manufacturers. As a fluorine element that reassures customers

Fluorine release film is also silicone paper or anti stick paper, mainly used to isolate sticky objects. The main features are as follows: firstly, the moisture-proof and temperature resistance of fluorine release film. The fluorine release membrane contains silicone oil, which has a certain degree of temperature resistance, but this mainly depends on the application of the product and the selection of domestic and imported silicone oil. Generally, the temperature of silicone oil can reach around 150 degrees. 2、 Peeling force of fluorine release film: Peeling force refers to whether the product can be easily torn off, although there are strict testing procedures. Small slitting machines, currently mainly using national standards internationally, have a stripping force unit of grams. According to the test results, the score is generally different

Below, the editor from the release film manufacturer will briefly introduce to you the common problems with PET release films! Tearing too tightly: 1. The ink viscosity is too low and cannot be dried thoroughly. In the actual production process, printers often like to lower the viscosity of ink in order to improve efficiency and fluidity. Although the adaptability of printing has been improved and efficiency has been improved, side effects have also come with it. This will cause the solvent in the ink to penetrate into the release layer, while increasing the difficulty of volatilization, resulting in us ultimately sealing all the solvents in the inner layer, forming a mixed release layer and ink layer. After hot stamping, during cold tearing, we continue to

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.
