Industrial Gelatin
Industrial gelatin is a kind of fine chemicals, a gelatin product classified according to the different uses of gelatin. It is characterized by light yellow or brown crumbs, no unpleasant smell, and no visible impurities. Its molecular weight is 15,000-250,000, it contains 18 kinds of amino acids, the water and inorganic salt content is less than 16%, and the protein content is more than 82%. It is an ideal protein source. According to its physical and chemical properties, industrial gelatin has many uses, and products with different freezing properties are widely used in boards, furniture, matches, feed, packaging, papermaking, textiles, silk, printing and dyeing, printing, ceramics, petroleum, daily chemicals, coatings Among various products in industries such as metallurgy and metallurgy, it mainly plays the roles of thickening, stabilizing, agglomerating, blending, glazing, sizing, bonding, and water fixing.

Physical and chemical properties of industrial gelatin
gelatin emulsifying properties
Gelatin is an effective protective colloid that prevents the aggregation of crystals or ions, stabilizes heterogeneous suspensions, and acts as an emulsifier in oil-in-water dispersions. Gelatin also has many excellent functional properties such as water holding capacity, film forming property, emulsifying property and foaming property.
Gelatin Chemical Properties
Gelatin does not coagulate when the concentration is below 5%, and usually forms a gel with a solution of 10% to 15%. The gelation temperature varies with the concentration, the type of coexisting salts, the pH of the concentration solution and other factors. The difference between the dissolution temperature and the solidification temperature is very small, it dissolves at about 30°C and solidifies at 20-25°C. Its gel is elastic and has a soft taste. Its aqueous solution is boiled for a long time, and its properties change due to decomposition. After cooling, it will no longer form a gel, and if it is reheated, it will become protein and peptone. If the gelatin solution is affected by formaldehyde, it becomes an irreversible gel that is insoluble in water.
Biodegradability
As a natural water-soluble biodegradable polymer material, gelatin has the advantage that the degradation products are easily absorbed without causing inflammation. When using the degradability of gelatin, it is often chemically modified to adjust its degradation rate to meet different needs.
Industry application
Papermaking surface sizing and coating
Whether used alone or in combination with other binder materials, gelatin coatings ensure improved paper coating processes by filling surface imperfections and increasing the smoothness of paper surfaces
Binder for complex chemical mixture of match heads
The surface-active characteristics of gelatin are very important for matches because the foaming properties of gelatin affect the ignition properties of the match.
Adhesive between paper substrate and sandpaper abrasive grains
During the manufacturing process, the paper backing is first coated with a concentrated gelatin solution and then sprinkled with grit of the desired size. Grinding wheels, discs and belts are prepared in a similar manner.
Adhesive of choice for phone book binding and sealing of corrugated board
Gelatin-based adhesives have slowly been replaced by various synthetic materials. However, in recent years, the natural biodegradability of gelatin adhesives has been increasingly valued.
