| Water-based paint production dispersant PD
Is a high temperature, corrosion, such as ceramic glass and stainless steel. Sulfonation reactor and the polycondensation reactor body made of stainless steel and electric heating means to meet the requirements of high temperature and corrosion. 3 technical indicators and technical indicators to use 3.1, the main technical economic indicators and performance are as follows: Appearance: Brown fine powder; Solubility: soluble in water; pH value: 9; stability: acid, alkali resistance, hard water and mineral salts; active ingredient: 85%; Na2SO4 content: 8%: Moisture content: 5%. 3.2 Usage (1) for carbon black pigments: take a certain amount of PD (amount of about 0.2% of the quality of carbon black), first mix it with water,uggs boots italia, then add carbon black pigments, together into the ball mill grinding 16h, to form a stable and liquid dispersion better. PD can be significantly improved by adding after the dispersion of pigment particles. (2) for latex paint: to take a certain amount of PD products (the amount of paint used per 100L 0.5 ~ 1kg), mix it with water after paint Mix together, form a good emulsion paint, which can greatly increase the dispersion and stability of emulsion paint. To increase the dispersion of PD, in the course can also work with other dispersants and surface active agent mixture, the better. Must be non-ionic surfactant or anionic,columbia sportswear outlet, cationic complex factors will affect the use of the product results. 3.3 Performance Comparison of domestic and foreign products now Chennai dispersant sodium salt condensation products, the United States and Western Europe, more advanced technology,mbt italia, excellent product performance. One brand name LomarPW, LomarD and dispersing agent NNO and other products, the performance is better than domestic products. United States of products produced LomarPW performance indicators: Brown fine powder, the active ingredient 87%, Na2SO4 content of 6.5%,moncler doudoune, 5% moisture content, soluble in hard water or soft water, pH value of 9.5 (10% solution). LomarPW products are widely used as a pigment, extender pigment and filler dispersant, emulsion polymerization process is also used for auxiliary emulsifier. Products compared with the LomarPW, PD lower active ingredient products (85%), Na2SO4 content slightly higher (8%), other indicators of performance and are close to LomarPW products. Also confirmed using Process: PD The effect is close to LomarPW products, can replace it. 4 Conclusion This paper introduces the water-based coating dispersant PD production process, the process is simple and feasible. PD with the same type of foreign income LomarPW product performance and technical indicators were compared, results showed that: PD of the performance indicators are close to LomarPW products, and use the results were quite good, similar foreign products can be used as a substitute for, worth manufacturer of the domestic industry application.
