存储: Store in a ventilated, cool and dry place, and keep away from fire,power, prevent humid, and avoid sun exposure. Handle with care during transportation to prevent damage to the package.It is strictly forbidden to store it with volatile chemicals to prevent deterioration by adsorption.

交通 While transporting, clean cars are needed, care needs to be taken to avoid moisture, rain and sun protection. Handle carefully to prevent damage to the packaging. Storage is very limited with temporary agents to prevent adsorption damage.

 

常见问题

Q: Is polyvinyl alcohol soluble?

A: Polyvinyl alcohol powder is water soluble with transparent solution. Most PVA series are used while dissolved in water. Its solubility depends mainly on degrees of polymerization and alcoholysis. At the same temperature, the solubility increases along with reduction of the degree of alcoholysis, and decreases with increase of the viscosity; for the PVA series with the same degree of polymerization, if their degrees of alcoholysis are low, their temperatures get low upon completion of dissolution, and vice versa; for the PVA of the same alcoholysis, if the degrees of polymerization are high, their temperatures get high upon completion of dissolution, and vice versa.
