    The core tip: in the 21st century, most of the coating products are developing towards the direction of environmental friendly and energy saving, towards the direction of water-based, high solid and powdered, so the dispersion of coating is particularly important As one of the most important auxiliaries in latex paint, Pd (sodium salt of macromolecular naphthalenesulfonaldehyde condensate) has a very broad development prospect It has a strong selectivity for paint pigment varieties, especially for carbon black pigment, which is the most difficult to disperse, with excellent dispersion performance, and is one of the best paint dispersants in China Its dispersive color paste is widely used in latex paint, and can be mixed with Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings news: in the 21st century, most of the coating products are developing towards the direction of environment-friendly and energy saving, towards the direction of water-based, high solid and powder, so the dispersion of coating is particularly important As one of the most important auxiliaries in latex paint, Pd (sodium salt of macromolecular naphthalenesulfonaldehyde condensate) has a very broad development prospect It has a strong selectivity for paint pigment varieties, especially for carbon black pigment, which is the most difficult to disperse, with excellent dispersion performance, and is one of the best paint dispersants in China The dispersive color paste is widely used in latex paint It can be mixed with anionic and non-ionic surfactants with better effect At present, the product is used in many domestic paint manufacturers and paint factories The main technical and economic indexes and properties of water-based paint dispersant PD are as follows: appearance: beige fine powder; solubility: soluble in water; pH value: 9; stability: acid and alkali resistance, hard water and inorganic salt resistance; effective composition: 85%; Na 2s04 content: 8%; water content: 5% Usage: (1) for carbon black pigment: take a certain amount of PD (the dosage is about 0.2% of carbon black mass), mix it with water first, then add carbon black pigment, put it into the ball mill for grinding for 16 hours, forming a stable dispersion with good fluidity The dispersion of pigment particles can be improved obviously by adding PD (2) for latex paint: take a certain amount of PD products (use 0.5 to 1kg per 100 L lacquer), mix it with water and mix with latex paint to form a good latex paint, which can greatly increase the dispersion and stability of latex paint In order to improve the dispersion of PD, it can be mixed with other dispersants and surfactants in the process of use, with better effect The surfactant must be non-ionic or anionic type, and the use effect of the product will be affected by the combination of cationic type Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
