FORMVAR RESIN - Introduction
POLY(VINYL FORMAL), also known as PVA, is a common synthetic material. The following is a description of the nature, use, formulation and safety information of PVA:
1. Nature:
- PVA is a colorless solid, soluble in water and alcohol, and has good peptization.
- PVA has high tensile strength, toughness and abrasion resistance.
- PVA maintains its strength and durability in humid environments.
- PVA is a non-toxic synthetic material that does not pollute the environment.
2. Use:
- PVA is widely used in textiles, paper, adhesives, gypsum mortar and coatings.
- PVA is used as a binder in textiles to improve the strength and wrinkle resistance of textiles.
- PVA is used in the paper industry to enhance the strength and durability of paper.
- PVA is also used as a suspension, mildew inhibitor and particle thickener.
3. Preparation method: The preparation of
- PVA is generally obtained by the condensation reaction of vinyl alcohol and formaldehyde. This reaction requires a catalyst and suitable reaction conditions.
-The preparation process needs to control the reaction temperature, reaction time and the amount of catalyst used.
4. Safety Information:
- PVA is a relatively safe synthetic material, but Formaldehyde vapor may be generated during the preparation process, and attention should be paid to ventilation and protection.
-When using PVA, avoid getting into the eyes and mouth to avoid irritation or poisoning.
-When handling PVA, care should be taken to avoid contact with flammable substances and avoid burning.
Please note that this is only a general introduction to POLY(VINYL FORMAL), and the specific use should follow the relevant safety operation specifications and production guidelines.
