Effect of Defoaming Masterbatch
In order to eliminate the moisture in plastic raw materials, a newly developed functional plastic masterbatch – defoaming masterbatch has brought a new way to solve the moisture problem in plastic raw materials. The plastic masterbatch defoaming masterbatch can adjust the addition ratio according to the moisture content of the raw materials. The plastic masterbatch has the characteristics of small addition amount (generally 2% to 4%), no change in processing technology, non-toxic, non-irritating, good plasticization, etc. Plastic masterbatch can absorb a large amount of plastic moisture during molding. Tianjin defoamer can be widely used in the processing of recycled materials, damp plastics and degradable plastics. Plastic masterbatch can ensure the yield rate, improve production efficiency, reduce energy consumption and ultimately reduce production costs while ensuring product quality. Due to its excellent product performance, it can meet the application requirements of many high-end products, such as being used in automotive paints, 2KPU industrial coatings or baking paint systems that require high gloss and high transparency, and disperse organic, inorganic and carbon black pigments. This product can effectively reduce grinding viscosity, thereby increasing pigment loading, and also has excellent pigment stability. Pigment dispersions based on TEGO® Dispers 670 not only have extremely low yield points, but also have excellent color development. Defoamers are ideal products for protecting coating surfaces from external environmental influences. They can keep the coating film’s appearance and feel for a long time, and give plastics, textiles, and leather surfaces special gloss and functionality. This original one-component silicone-modified polyurethane dispersion can be diluted with water and maintains high flexibility and elasticity in both hot and cold conditions. The quality of circulating water directly affects the safe production of subsequent main devices. To ensure the quality of circulating water, in addition to adding daily chemicals, non-oxidizing biocides and defoamers should be added to the system from time to time to prevent the growth of microorganisms, which will cause system erosion and affect safe production.
