P\u00f3 fino de \u00e1lcool polivin\u00edlico JOYFORCE<\/p>\n

Como aditivo para cimento e argamassa, o PVA pode aumentar efetivamente a ades\u00e3o e a fluidez do cimento e da argamassa, retardar o tempo de secagem da superf\u00edcie do cimento, aumentar a adaptabilidade do revestimento e evitar rachaduras na superf\u00edcie do tecido de cimento. \u00c9 adequado para a caia\u00e7\u00e3o de paredes, tetos e colagem de azulejos gra\u00e7as ao seu m\u00e9todo de aplica\u00e7\u00e3o simples com os efeitos desejados.<\/p>\n

O PVA tamb\u00e9m pode ser usado como adesivo para a forma\u00e7\u00e3o de placas, tais como: placas pr\u00e9-fabricadas de gesso, placas de absor\u00e7\u00e3o de som, etc., sejam elas fibras org\u00e2nicas (baga\u00e7o de cana, lascas de madeira) ou materiais inorg\u00e2nicos, elas podem ser equipadas com as caracter\u00edsticas de alta efici\u00eancia de ades\u00e3o e resist\u00eancia \u00e0 \u00e1gua do PVA para fazer a compress\u00e3o e a colagem em uma folha. O PVA tamb\u00e9m tem bons usos em revestimentos. A solu\u00e7\u00e3o aquosa de PVA \u00e9 catalisada por \u00e1cido clor\u00eddrico e o formalde\u00eddo \u00e9 condensado para formar um composto de pol\u00edmero formal de PVA resistente \u00e0 \u00e1gua, que \u00e9 amplamente utilizado como revestimento de paredes internas e externas, acabamento, calafetagem etc. de edif\u00edcios. O revestimento de PVA tem boa resist\u00eancia a intemp\u00e9ries, resist\u00eancia \u00e0 \u00e1gua, n\u00e3o incha quando exposto \u00e0 \u00e1gua, n\u00e3o se fragiliza, n\u00e3o \u00e9 t\u00f3xico, n\u00e3o tem gosto e tem as vantagens do baixo pre\u00e7o. Nesse campo, as variedades tradicionais s\u00f3 podem ser usadas na fabrica\u00e7\u00e3o de placas de forma\u00e7\u00e3o. No campo do revestimento, o PVA tem um grau mais alto de polimeriza\u00e7\u00e3o.<\/p>\n\n\n\n\n\n\n\n\n\n
