Polyvinyl alcohol is a synthetic polymer compound and an important industrial raw material.
Polyvinyl alcohol, also known as polyvinyl alcohol ether, is a synthetic polymer compound polymerized from vinyl alcohol monomer, which has good solvent, surface activity and biocompatibility. It is widely used in medicine, textile, paper, building materials and other industrial fields. In the textile industry, polyvinyl alcohol can be used as a spinning solvent, fabric lubricant and anti-shrinkage agent; in the paper industry, polyvinyl alcohol can be used as a coating agent and reinforcing agent; in the field of building materials, polyvinyl alcohol can be used as concrete crack resistance, water resistance and other additives. In addition, polyvinyl alcohol can also be used to prepare artificial cornea, artificial bone and other biomedical materials.
It should be noted that polyvinyl alcohol has strong hygroscopicity and needs to be sealed for storage; at the same time, the nature of polyvinyl alcohol varies with the degree of polymerization, and users should choose an appropriate amount of polyvinyl alcohol to meet different application requirements.
