He paints phosphate series products as environmentally friendly rust inhibiting the development of the future development of paint the main direction, separate the zinc phosphate, especially for water soluble difference early rust inhibiting effects, such as water-based coatings for corrosion in imitation of Flash does not work, in order to enhance and improve the performance of the phosphate series products, for more than 20 major paint years taken at home and abroad by technical means and chromate crystalline, fineness and surface particle size distribution, modification, and so on control and stable period of aqueous solution, as well as suitable solvent and water dispersion of synergistic phosphate compound, and preparation of different metals phosphate compound synergistic effect is reached.
At present the German company has launched its third generation products, zip-modification of zinc sulfate hydrate, calcium phosphate almost now all the solvent-based coatings system can select and use products, currently Tianjin chemical industry Research Institute and Guangxi chemical industry Research Institute have developed intend trimmer aluminum sulfate. There is also a zinc sulfate aluminum salts, but in terms of surface modification of the serialization of the product and the gap between large companies outside Headquarters, we should, of zinc sulfate tablets of paint acid system is different, the total quantity of antisepsis pigment at a wider range of changes in the test by formula takes a decision. Partial shed barium titan ate, etc.
Virus-free antisepsis pigments, currently in antiseptic coatings, are used by itself does not clear that the General and chromate or phosphate in combination, in the water-based paints in effect we use bubbles paint films caused by zinc oxide itself does not possess outstanding corrosion resistance, but paints almost indispensable assisted pigments, at least he can and resin or corrosion to acid produced by the reaction to maintain medium flakes of environment, pollution prevention, he can paint as oxidation Atone exudation regulators of anti-fouling agents, assisted by inert and shielding pigment in the corrosion resistant coatings, heavy use of iron oxide, black iron oxide red iron oxide, yellow iron oxide pigments, apart from inert coloring, they also have the effect of filling shield, f-ferric oxide maximum dosage.
There is also a natural clay, Red Earth in iron oxide content with different origin under 70 ~ 90% oscillations synthesis of now primarily use as antiseptic ferric oxide pigments, on red iron content of electrolytes in there should be strict control ferric can dispersion and surface modification and Good Year gap between the company's products. Cheap domestic production now red paint general control fineness is less than 80 μm, there are also products using natural Red Earth, how to improve their dispersion is worthy of attention.
