In daily life, people divide gelatin into food gelatin, medicinal gelatin, photographic gelatin and industrial gelatin. Among them, industrial gelatin can be divided into skin gelatin, bone gelatin, hot sol powder, protein gelatin, feed gelatin, match gelatin and so on.

Industrial gelatin is a fine chemical that is classified into gelatin products according to the different uses of gelatin. It is a pale yellow or brown particle with no unpleasant odor and no visible impurities. Its molecular weight of 10-100,000, containing 18 kinds of amino acids, water and inorganic salt content of less than 16%, protein content of more than 82%, is an ideal protein source.

The use of industrial gelatin: First, it is used in the match manufacturing industry, which mainly uses the foaming property of colloids to form pores, and combines with oxidants, igniters and fillers to ignite them instantaneously. The second is as an adhesive, using its high strength, high elasticity, high toughness, the production of emery cloth, sandpaper, bonded wood, bound books, for gift box assembly line, Musical Instruments, furniture industry.

The third is electrolysis, which helps to produce a smooth and dense anode precipitation by adding an electrolyte, eliminating production losses. Fourth, it is used for textile fabrics, which can form a film on the yarn bundle to increase the toughness, strength, smoothness and elasticity of the fiber and prevent breakage. Fifth, with bichromate to produce negative photosensitive corrosion resistant film. Sixth, hydrolyzed proteins are extracted and used as additives.

In short, industrial gelatin is widely used in board, furniture, matches, feed, packaging, papermaking, textile, silk, printing and dyeing, printing, ceramics, petroleum, daily chemical, coatings, metallurgy and other industries in a variety of products, mainly plays a thickening, stability, cohesion, blending, polishing, sizing, bonding, water fixing and other roles.
