Non-stick coating refers to the coating formed after coating with low surface energy, easy to clean and other characteristics of the coating, which is widely used in all kinds of food contact, hardware products, mechanical parts, chemical equipment, electrical equipment. Non-stick pans are also the most widely recognized non-stick paint application scenarios. 1, non-stick coating has fluorine resin system, silicone system, ceramic system three mainstream products. At present, the non-stick coatings on the market are mainly divided into fluorine resin non-stick coatings, silicone non-stick coatings and ceramic non-stick coatings, among which fluorine resin non-stick coatings are the mainstream, fluorine resin non-stick coatings can be divided into polyimide binders and polyaryl ether binders according to the differences in binders. In the future, polyaryl ether binders will be the direction of technological evolution. According to the type of solvent, it is divided into water-based non-stick coating, oily non-stick coating, powder non-stick coating, and water-based non-stick coating is the mainstream at present. 2, fluorine resin non-stick coating: performance "unique", generally need special engineering plastics as adhesive use. Fluorine resin non-stick coating is usually PTFE based PTFE, PFA, FEP three mixture of the form exists, binder to polyimide, polyaryl ether two types of special resin based, coating performance to composite multi-coating is best, fluorine resin non-stick coating has the best non-stick and comprehensive protection effect, in addition to the field of kitchenware and home appliances has a better application, Fluorine resin non-stick coatings can also be widely used in harsh acid, alkali, salt, high temperature protection, lubrication requirements, such as chemical reactors, large industrial nuts and bolts. However, due to the high melting point of fluorine resin and adhesive resin, the coating film baking temperature is high and the energy consumption is large, the adhesive resin is difficult to water-based processing and high energy consumption, and it is difficult to avoid the use of high temperature solvent when baking film, which limits the further improvement of fluorine resin non-stick coating in environmental protection. Fluorine resin PTFE, PFA, FEP are perfluoroppolymer, molecular chain structure due to C-F bond, its bond energy of 485kJ/mol, in all chemical bonds can be called the first, long-term use temperature 220℃, almost with all substances are not bonded, with excellent chemical stability, heat resistance, acid and alkali resistance, flame retardant, aging resistance and self-lubrication. Applied to non-stick coatings, in the range of cooking oil smoke temperature 180℃, fluorine resin structure is stable, safe and reliable, its low surface energy properties can effectively prevent food oil, protein and other materials adhesion and penetration, so it becomes the ideal choice for manufacturing non-stick coating...

Color printing packaging is light in weight, easy to carry, and the source of raw materials is wide, and it is widely used in food, traditional Chinese medicine, daily necessities and other industries. Do you know what are the common production processes of packaging? First, the film Laminating process is a kind of surface processing process, after printing is completed, this process is also called "plastic", "laminating", "laminating", through hot pressing on the surface of paper products with a layer of transparent plastic film, so that the surface of the printed matter more shiny, on the other hand, the printed matter also played a protective role, this is laminating, at present, The film coating process is often used for book covers, picture albums, postcards and maps. Two, hot stamping Hot stamping is to first make the pattern or text that needs to be hot stamped into a convex plate, and with the help of hot pressing method, a variety of aluminum foil sheets are printed on the substrate, showing a strong metallic light, so that the product has a good texture. It is often used for decoration of household appliances and electronic products. Three, die cutting indentation Die-cutting indentation is a process of post-printing processing, which will no longer limit the edge shape to right angles according to its own desired graphic specifications. The indentation process is to use a wire cutter or a wire die to press out line marks on the sheet material through the action of pressure, or use a rolling wheel to roll out line marks on the sheet material, so that the sheet material can be bent and formed according to a predetermined position. With the improvement of people's exquisite degree of product printing and environmental protection requirements, there are more and more production methods of printing and packaging, as long as one of the above processes is mastered, it will be able to better speed up the production process.

Water-based adhesives for printing are very common, which mainly include water-based pasting adhesive, laminating adhesive, water-based sealing adhesive and so on. Water-based laminating adhesive Water-based film adhesive has been widely used in recent years for its high brightness, low cost, easy operation and water-based environmental protection. Water-based film adhesive is mainly divided into cold paste composite and dry composite two kinds. The current market is mainly based on cold paste composite, but the development speed of dry composite is getting faster and faster. Water-based cold-paste coating machine covers less land, consumes less power and is easy to operate. The water-based dry film coating powder has strong ability, high stiffness of the finished product, strong adhesion, and good adaptability to ink. Water-based sealant Adhesive With the improvement of people's demand for packaging aesthetics, binding can no longer be met. Therefore, using adhesive to seal printed matter has become a good choice. The water-based sealant has become the mainstream of the market because of its water-based environmental protection, flexible film and good aging resistance. Water-based sealers are generally milky white to slightly yellow viscous liquid. The water-based sealers of different manufacturers have great differences in opening time, initial viscosity, durability, odor and appearance. It is suggested that when people in the industry choose, they should make full tests on the low temperature resistance, durability and peel strength of the bonded products before choosing, and try to choose manufacturers with large output and high quality control level. Sinograce Chemical produces all kinds of water-based glue, acrylic glue.It has strong adaptability to various printing surfaces, good initial adhesion, high bonding strength, good leveling properties, excellent film-forming speed, fast drying of composite products, good stiffness, and good pasting resistance. It is used for dry lamination of paper and PET/BOPP films. It has good adaptability to hot hot stamping products . It can adapt to a wide temperature range and has excellent cost performance. The process is simple, easy to operate and environmentally friendly.
