Different processing methods will cause different fault manifestations, the following we mainly analyze the causes of paper thermit sealing delamination phenomenon under the gravure and solvent-free composite processing methods. The YBB paper aluminum-plastic composite film standard does not specify the composite strength index of the paper aluminum layer in the paper aluminum-plastic composite fi...
The high adhesion base coating improves the adhesion of the inkjet coating on PP paper Prevent ink from penetrating into PP composite paper substrate Fast drying speed to meet the needs of production line Good weather resistance, no yellowing Easy to use, safe and environmentally friendly Anhui sinograce company's PP composite paper digital inkjet coating adhesive base | Inkblot coating base ...
PTFE coatings (polytetrafluoroethylene) are non-stick, fluoropolymer containing high temperature coatings, they have a single coating system or a double coating system of primer and top coat, and have a variety of properties. The Teflon spray process is an important surface treatment that gives objects outstanding properties. With the right preparation, spraying procedures and techniques, Teflon s...
The most important difference between non-stick cookware and ordinary cookware is that the surface is coated with a layer of non-stick paint, and the Teflon non-stick cookware commonly used on the market is to coat the main raw material of fluorinated resin such as polytetrafluoroethylene coating on the metal surface such as aluminum, copper or iron, and through sintering. Properties of NI-PTFE co...
First: the treatment of the substrate First, the substrate (aluminum, stainless steel or other metal substrate) is baked at high temperature (360℃×30 minutes ~380℃×10 minutes) to carbonize the grease or degreaser cleaning for the first step of degreasing. Step 2: Roughening the surface Available corundum sand 80#~120#, pressure 0.4~0.6mpa, sandblasting, so that the surface roughness of the substra...
Teflon is the abbreviation of polytetrafluoroethylene, this material has the characteristics of acid and alkali resistance, resistance to various organic solvents, almost insoluble in all solvents, so it has the title of "non-stick coating". With the development of thermal spraying technology, Teflon coatings can be applied to stainless steel, copper, aluminum, magnesium and various alloy metal ma...
Classification of surfactant applications in coatings: According to the role of the classification, the coating industry used surfactants can be divided into the following categories: emulsifier, pigment surface treatment agent, pigment wetting dispersant, defoamer, levelling agent, anti-mold, fungicide, antistatic agent, brightening agent, slippery agent and so on. Application of surfac...
Main properties of Teflon coating Teflon high-performance special coating is a fluorine coating based on polytetrafluoroethylene matrix resin, the English name is Teflon, because of the pronunciation, it is usually called Teflon, Teflon, Teflon, Teflon, etc. (all are translations of Teflon). Teflon coatings are a unique, high-performance coating that combines heat resistance, chemical inertia, exc...
Teflon coating is one of the commonly used protective coatings in metal thermal spraying processing technology services, with good non-stick, wear resistance, corrosion resistance, high temperature resistance and other characteristics, can be applied to carbon steel, stainless steel, aluminum, copper, magnesium and various alloys and other metal materials. It can also be applied to non-metall...
Many people think that the temperature of the primer baking (dry) of Teflon paint is not important, just bake it, in fact, this is a misunderstanding. If you usually encounter the following situations, please carefully bake the primer. For the primer coating of Teflon paint, we recommend a temperature of 150 ° C, after the workpiece reaches 150 ° C, bake for 5-10 minutes. I. If the temperature of ...
Insufficient or uneven amount of glue due to insufficient amount of glue produced by the white spot can be observed in the composite machine. In the dry composite process, the coated adhesive must be able to fill the bumps and bumps on the surface of the ink and film to avoid appearance defects such as obvious white spots. When the water-based adhesive dry composite is used to produce lightweight ...
Due to the hydrophobic properties of waterborne polyurethane resin, it is difficult to dissolve in water or disperse uniformly, and the high reactivity of isocyanate groups to water, the direct synthesis of waterborne polyurethane faces many challenges. Therefore, to achieve the preparation of waterborne polyurethane, the primary strategy is to cleverly integrate hydrophilic functional groups (suc...
Paper aluminum-plastic composite film in the actual application of medical packaging powder, granule packaging products compared to the plastic aluminum-plastic packaging commonly used in the market now has the following advantages: (1)The mechanical strength of the paper is high, the rigidity is good, and the ability to maintain the bag after forming is strong, which improves the cleanliness of t...
First, what is the adhesion of resin Resin adhesion refers to the ability of the resin coating to adhere to the substrate. Insufficient adhesion of the resin on the surface can cause it to fall off or foam, and affect the service life and performance of the product. Second, how to effectively improve the adhesion of resin 1. Surface treatment Surface treatment is an effective method to improv...
(1) The use of hydrosol Hydrosol is a polymeric dispersion of very small particles, which has the characteristics of both emulsion system and solution system, and can effectively improve water resistance (2) Reduce the amount of emulsifier Although emulsifier plays an important role in the formation of micelles in polymerization and the stability of the polymerization emulsion, it is als...
Water-based viscosification emulsion plays a very important role in water-based acrylic pressure sensitive adhesive, which can improve the adhesion strength and initial viscosity of pressure sensitive adhesive on high and low energy surface, so as to achieve the best balance point, and improve the application range and grade of pressure sensitive products. Today, I will introduce you to the applic...
