Properties and applications of PVA 1788

Polyvinyl alcohol 1788 is a colorless, transparent, viscous polymer compound consisting of alternating arrangements of vinyl and hydroxyl units. It is often used in the preparation of glue, coatings, textiles, medicine and other fields.

Polyvinyl alcohol 1788 has good solubility, can be dissolved in water, can also be dissolved in alcohols, esters and other organic solvents. Its solubility decreases with the increase of molecular weight. In dry air, PVA 1788 is relatively stable, but it breaks down in sunlight.

Polyvinyl alcohol 1788 is an important polymer material, which is widely used in various fields. The main uses of PVA 1788 are as follows:

1. Glue preparation
PVA 1788 can be used to prepare various glues, such as woodworking glue, paper glue and so on. Dissolve PVA 1788 in water, then add crosslinking agent and auxiliary agent, after stirring, filtration, defoaming and other process steps, you can get glue.

2. Coating preparation
PVA 1788 can be used to prepare various coatings, such as wall coatings, wood coatings and so on. The polyvinyl alcohol 1788 is dissolved in water, and then added pigments, fillers, auxiliaries, etc., after mixing, grinding, filtration and other process steps, the paint can be obtained.

3. Textile processing
PVA 1788 can be used in textile processing, such as the processing and printing of cellulose fibers. Dissolve PVA 1788 in water, then add dyes, additives, etc., after soaking, drying and other process steps, dyed cellulose fiber can be obtained.

4. The field of medicine
PVA 1788 can be used to prepare medicine, such as oral medicine, injections, eye drops and so on. Dissolve PVA 1788 in water, then add drugs, auxiliaries, etc., after mixing, filtration, sterilization and other process steps, you can get the drug.
