Role of gelatin
Industrial gelatin, a fine chemical, is a kind of gelatin product divided according to the different uses of gelatin. In daily life, people divide gelatin into edible gelatin, medicinal gelatin, photographic gelatin and industrial gelatin. For industrial gelatin, it is divided into leather glue, bone glue, hot sol powder, protein special glue, feed special glue and match special glue. Wait.
Industrial gelatin, is a light yellow or brown particles, no discomfort, no visible impurities. Its molecular weight is 1-100000, containing 18 kinds of amino acids, water and inorganic salt content below 16%, protein content above 82%, is an ideal protein source.
One is used in the match manufacturing industry, which mainly uses the foaming property of colloid to form pores, combined with oxidant, fire agent and filler to make it ignite instantly. The second is as an adhesive, using its high strength, elasticity and toughness to produce emery cloth, sandpaper, bonded wood, binding books, and used in gift box assembly lines, advanced musical instruments, and furniture industries. The third is electrolysis, which is added to the electrolyte to help generate a smooth and dense anode precipitate and eliminate production losses. Fourth, it is used for textiles, and a film can be formed on the yarn bundle to increase the toughness, strength, smoothness and elasticity of the fiber and prevent breakage. Fifth, it is combined with dichromate to produce negative photosensitive corrosion-resistant film. Six is the extraction of hydrolyzed protein, used in additives.
In short, industrial gelatin is widely used in plate, furniture, matches, feed, packaging, paper, textile, silk, printing and dyeing, printing, ceramics, petroleum, daily chemical, coating, metallurgy and other industries in a variety of products, and in which mainly from thickening, stability, cohesion, reconciliation, glazing, sizing, bonding, solid water and so on.
