Uso do poli(acetato de vinila)<\/strong><\/h2>\n

1. Como base de goma, as regulamenta\u00e7\u00f5es da China podem ser usadas para sabores e gomas emulsionados, o uso m\u00e1ximo \u00e9 de 60g\/kg.<\/p>\n

2. Usado para fabricar veludo de brinquedo e tecido n\u00e3o tecido<\/p>\n

3. Usado como mat\u00e9ria-prima para \u00e1lcool polivin\u00edlico, copol\u00edmero de acetato de vinila e cloreto de vinila, copol\u00edmero de acetato de vinila e etileno, tamb\u00e9m usado na prepara\u00e7\u00e3o de revestimentos, adesivos etc.<\/p>\n

4. Usados principalmente como revestimentos, adesivos, papel, bases de goma de mascar e agentes de acabamento de tecidos, bem como mat\u00e9rias-primas para \u00e1lcool polivin\u00edlico e acetal polivin\u00edlico<\/p>\n

5. O agente de revestimento de frutas evita a evapora\u00e7\u00e3o da umidade e desempenha um papel na preserva\u00e7\u00e3o do frescor.<\/p>\n

6. A resina termopl\u00e1stica \u00e9 hidrolisada em \u00e1lcool polivin\u00edlico em um solvente \u00e1cido ou alcalino para preparar uma mat\u00e9ria-prima principal de \u00e1lcool polivin\u00edlico. Quando a mol\u00e9cula cont\u00e9m um fotossensibilizador, ela \u00e9 sens\u00edvel \u00e0 luz e sofre uma rea\u00e7\u00e3o de decomposi\u00e7\u00e3o sob a a\u00e7\u00e3o de luz ultravioleta ou feixe de el\u00e9trons, e tem uma propriedade positiva de resina fotossens\u00edvel. O acetato de polivinila \u00e9 sol\u00favel em uma variedade de solventes org\u00e2nicos e pode ser copolimerizado com uma variedade de mon\u00f4meros com liga\u00e7\u00f5es duplas para introduzir v\u00e1rios grupos funcionais com propriedades diferentes. \u00c9 frequentemente usado como aglutinante.<\/p>\n

7. Usado como mat\u00e9ria-prima para \u00e1lcool polivin\u00edlico, copol\u00edmero de acetato de vinila e cloreto de vinila, copol\u00edmero de acetato de vinila e etileno, tinta, aglutinante, chiclete, etc.<\/p>\n
