Production method 1: Avicel Cellulose is the most abundant all-natural polymer compound worldwide. The raw products for producing originated from timber, cotton, cotton linter, wheat straw, straw, reed, hemp, mulberry bark, mulberry bark as well as bagasse. Because of the absence of forest sources in my nation, 70% of the raw products of Avicel Cellulose originate from non-timber sources. The average cellulose material of coniferous and also broad-leaved hardwood in my country pertains to 43-45%; the average cellulose internet material of yard stems involves 40%. The commercial manufacturing strategy of cellulose is to use sulfite solution or alkali solution to cook plant resources, primarily to remove lignin, which are called sulfite strategy as well as antacid approach particularly. The resulting products are called sulfite pulp and alkaline pulp. The recurring lignin wants that even more removed by whitening, and additionally the resulting blonde pulp can be made use of for papermaking. After even more removal of hemicellulose, it can be used as a basic material for Avicel Cellulose by-products.
Manufacturing technique 2: The fibrous plant product and also inorganic acid are pounded into pulp to make α-cellulose, and afterwards Avicel Cellulose is partly depolymerized by therapy, as well as after that the amorphous element is gotten rid of and detoxified.
Production technique 3: spread the selected business wood pulp board, as well as after that send it into a reaction pot that has actually added 1% to 10% of hydrochloric acid (the dose is 5% to 10%) for home heating as well as additionally hydrolysis, as well as the temperature degree is 90 to 100 ° C. The minute is 0.5-2h. After the reaction is finished, it is cooled down in addition to sent to the neutralization container, as well as is gotten used to nonpartisanship with fluid caustic soda.
Manufacturing method four: Avicel Cellulose made from wood pulp or cotton pulp. It is fine-tuned after lightening as well as mechanical diffusion.
