저장소: 통풍이 잘되고 서늘하고 건조한 곳에 보관하고 불, 전원을 멀리하고 습기를 방지하고 햇빛에 노출되지 않도록하십시오. 포장의 손상을 방지하기 위해 운송 중에 조심스럽게 취급하고 흡착에 의한 변질을 방지하기 위해 휘발성 화학 물질과 함께 보관하는 것은 엄격히 금지되어 있습니다.
교통편: 운송 중에는 깨끗한 차량이 필요하며 습기, 비, 자외선 차단을 위해 주의를 기울여야 합니다. 포장이 손상되지 않도록 조심스럽게 다루세요. 흡착 손상을 방지하기 위해 임시 약품을 사용하여 보관하는 것은 매우 제한적입니다.
자주 묻는 질문
Q: 폴리비닐 알코올은 용해되나요?
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. The PVA at the degrees of alcoholysis above 88 (mol/mol)% depends greatly on temperature changes, that is, dissolution or partial swelling may not take place at a particular temperature.
