The quality of crushing can be controlled by the transformation of the Analyzer and the adjustment of the rotating speed of the Analyzer. At the same time, other crushing equipment can be used, such as mill, air flow mill and hammer mill.
English name of paint: paint or coating. Paint is a kind of chemical mixture paint that can be firmly covered on the surface of objects for protection, decoration, signs and other special purposes. The book Paint Technology compared by the coating industry defines as follows: "Paint is a kind of material, which can be coated on the surface of an object with different construction processes to form a solid film with firm adhesion, certain strength and continuity. The film thus formed is generally called a coating film, also called a paint film or coating."
The coating generally consists of four parts: film-forming materials, fillers (pigments and fillers), solvents, and additives. Sometimes the composition will change slightly according to the performance requirements, for example, there is no pigment or filler in the varnish, and there can be no solvent in the powder coating.
It belongs to organic chemical polymer material, and the film formed belongs to the type of polymer compound. According to the classification of modern chemical products, coatings belong to fine chemical products. Modern coatings are gradually becoming a kind of multi-functional engineering materials, which is an important industry in the chemical industry.
Tianshui recovery acrylic resin Tianshui recovery acrylic resin 4 circulating water pre film preparation is completed, the amount of bactericidal and algal inhibitor and corrosion and scale inhibitor is sufficient, and the weighing is accurate. 5 The cooling exchange equipment of the system has been treated during the flushing process, and there is no leakage or abnormality at each connection, which can be put into use at any time. Three operating steps 1. After the circulating water system is flushed and replaced, the pipeline shall be cleaned and prefilmed. See the prefilming scheme of the circulating water system for specific steps. After prefilming, the water will be replaced and then turned into cold state operation. The return water will not enter the water tower, but will enter the circulating water pool through the auxiliary line. During normal operation, it is necessary to add bactericidal and algal killing agents, corrosion and scale inhibitors to the pool regularly. The specific methods are as follows: Ⅰ. The bactericide and algaecide shall be added once a month in January, February, March and April; Once every two days in January; Once every 15 days; And once a month in December.
