Superior Mechanical And Physical Properties: HSHM PVA fiber has high tensile strength and modulus, low elongation. The tensile strength is not inferior much to steel bar and elastic modulus can match with concrete’s. It can improve the early strength of concrete, but also the tensile strength of concrete in the late, can greatly save construction …
Pharmaceutical excipients are excipients and adjuncts used in the production of drugs and prescription, and are an important part of pharmaceutical preparations. As a natural polymer derived material, cellulose ether is biodegradable, non-toxic and inexpensive. Cellulose ether, such as sodium carboxymethyl cellulose, methyl cellulose, hydroxypropyl methyl cellulose, hydroxypropyl cellulose, hydroxyethyl cellulose and ethyl cellulose, has …
There’s a production method for PVA based on carboxyl group modification as following steps: S1: Mix vinyl acetate with the second copolymer and add solvent to get the raw material mixture S2: The initial polymerization reaction is carried out in the first polymerization kettle S3: The third copolymer and initiator are gradually added to the …
