1. L'alcool polyvinylique est soluble dans l'eau et doit g\u00e9n\u00e9ralement \u00eatre chauff\u00e9 \u00e0 65\uff5e75\u2103 pour se dissoudre compl\u00e8tement. Il est l\u00e9g\u00e8rement soluble dans le sulfoxyde de dim\u00e9thyle. Il est soluble dans le glyc\u00e9rol \u00e0 120\uff5e150\u2103, mais devient g\u00e9latineux lorsqu'il est refroidi \u00e0 temp\u00e9rature ambiante.<\/p>\n

2. Pour dissoudre l'alcool polyvinylique, le mat\u00e9riau doit \u00eatre ajout\u00e9 \u00e0 de l'eau \u00e0 temp\u00e9rature ambiante sous agitation. Il faut le disperser uniform\u00e9ment et le chauffer pour acc\u00e9l\u00e9rer la dissolution, ce qui permet d'\u00e9viter la formation d'une masse et d'influer sur la vitesse de dissolution. La solution aqueuse d'alcool polyvinylique (5%) est tr\u00e8s sensible au borax et \u00e0 l'acide borique, ce qui provoque facilement une g\u00e9lification. Lorsque le borax atteint 1% de la masse de la solution, une g\u00e9lification irr\u00e9versible se produit.<\/p>\n

3. Le chromate, le bichromate et le permanganate peuvent \u00e9galement produire un gel d'alcool polyvinylique. La viscosit\u00e9 de la solution aqueuse de PVA 17-88 augmente progressivement avec le temps \u00e0 temp\u00e9rature ambiante. Mais la viscosit\u00e9 lorsque la concentration est de 8% est absolument stable et n'a rien \u00e0 voir avec le temps. Le ph\u00e9nom\u00e8ne particulier c Le PVA a de bonnes propri\u00e9t\u00e9s de formation de film et est tr\u00e8s d\u00e9sagr\u00e9able pour de nombreux gaz, \u00e0 l'exception de la vapeur d'eau et de l'ammoniac.<\/p>\n

4. Bonne r\u00e9sistance \u00e0 la lumi\u00e8re, non affect\u00e9e par la lumi\u00e8re. Il peut br\u00fbler dans un feu ouvert et a une odeur particuli\u00e8re. Les solutions aqueuses deviennent parfois toxiques lorsqu'elles sont stock\u00e9es. Non toxique et non irritant pour la peau humaine.<\/p>\n
