1. the reason why non-stick pot is not stick, all rely on the coating material on the surface of the pot. These coating materials have good lubricity, small friction coefficient, small surface tension, food is not easy to stick to the pot.Two types of coating materials are commonly used for nonstick pans: fluoropolymers, such as teflon, and silicone polymers. Non-stick wok use PFOA-free high quali...
First: Teflon coating introduction Industrial Teflon coating is suitable for plastic rubber mold, ball mold, glove mold, latex mold, roller, conveyor belt, mechanical parts and other surface treatment, containing "FEP" and "PTFE" polytetrafluoroethylene ingredients with high-performance resin, divided into the bottom coating and surface coating a total of two layers, has the best anti-corrosion, h...
Water dispersion system is commonly used to analyze the relationship between surfactant structure and dispersion.As a hydrophobic solid particle, it can adsorb the hydrophobic group of the surfactant, and if it is an anionic surfactant, the outward-facing hydrophilic genes have the same charge and repel each other. Obviously, the adsorption efficiency of surfactants increases with the increase of ...
Defoamer is a substance with low surface tension and high surface activity, which can inhibit and eliminate foam in the liquid, that is to say, defoamer can reduce the surface tension of water, solution, suspension, etc., to prevent foam generation or eliminate the original foam.Long-term defoaming is also known as defoaming, and the length of the defoaming time is the main sign of the quality of ...
One,Overview Paper-plastic composite can make the surface of paper printed matter more bright, smooth and color more bright and full of three-dimensional sense, but also play a role in moisture, anti-fouling, anti-counterfeiting, folding resistance, wear resistance and so on.It has been widely used and rapidly developed in printing and packaging industry at home and abroad. The market demand for p...
First, the choice of self-adhesive printing raw materials When selecting raw materials, we must choose high-quality self-adhesive materials with qualified physical and chemical indexes, rather than products with expired or unstable physical and chemical indexes. Although the latter price is low, but due to the unstable quality of such materials, large consumption in each process, and even lead to ...
In the production process of water-based polyurethane to add a certain type of additives, it is necessary to pay attention to its role in the various stages of storage, construction, application, and consider and evaluate its role and impact in the next section. For example, when the water-based polyurethane paint is operated with wetting and dispersing agents, it plays a certain role in storage a...
The main difference is that the nature is different, the production process is different, and the characteristics are different, as follows: First, the nature is different 1.Flexo printing Flexo printing is a direct printing method known as flexo printing because of the use of elastic, raised image plates. 2.Gravure printing Gravure refers to gravure printing, first the printing plate on the exces...
