JOYFORCE Alcool polyvinylique en poudre fine<\/p>\n

En tant qu'additif pour le ciment et le mortier, le PVA peut augmenter efficacement l'adh\u00e9rence et la fluidit\u00e9 du ciment et du mortier, ralentir le temps de s\u00e9chage de la surface du ciment, augmenter l'adaptabilit\u00e9 du rev\u00eatement et emp\u00eacher la surface de la toile de ciment de se fissurer. Il convient pour le badigeonnage des murs et des plafonds et pour le collage des carreaux gr\u00e2ce \u00e0 sa m\u00e9thode d'application simple avec les effets souhait\u00e9s.<\/p>\n

Qu'il s'agisse de fibres organiques (bagasse de canne \u00e0 sucre, copeaux de bois) ou de mat\u00e9riaux inorganiques, les caract\u00e9ristiques d'adh\u00e9rence et de r\u00e9sistance \u00e0 l'eau du PVA lui permettent de se comprimer et de se lier en une feuille. Le PVA est \u00e9galement utilis\u00e9 dans les rev\u00eatements. La solution aqueuse de PVA est catalys\u00e9e par l'acide chlorhydrique et le formald\u00e9hyde est condens\u00e9 pour former un compos\u00e9 polym\u00e8re formel PVA r\u00e9sistant \u00e0 l'eau, qui est largement utilis\u00e9 pour les rev\u00eatements muraux int\u00e9rieurs et ext\u00e9rieurs, la finition, le calfeutrage, etc. des b\u00e2timents. Le rev\u00eatement PVA r\u00e9siste bien aux intemp\u00e9ries et \u00e0 l'eau, ne gonfle pas lorsqu'il est expos\u00e9 \u00e0 l'eau, ne se fragilise pas, n'est pas toxique, n'a pas de go\u00fbt et pr\u00e9sente l'avantage d'\u00eatre bon march\u00e9. Dans ce domaine, les vari\u00e9t\u00e9s traditionnelles ne peuvent \u00eatre utilis\u00e9es que pour la fabrication de plaques de formage. Dans le domaine du rev\u00eatement, le PVA a un degr\u00e9 de polym\u00e9risation plus \u00e9lev\u00e9.<\/p>\n\n\n\n\n\n\n\n\n\n
