Abstract

REVESTIMENTO ELASTOMÉRICO PARA CILINDROS DE FABRICAÇÃO DE PAPEL OU CILINDROS DE CONSERVAÇÃO ÁCIDA E ESTEIRA DE PRENSA DE CALÇADO PARA FABRICAÇÃO DE PAPEL. As concretizações da invenção provê o equipamento do moinho de papel que pode melhor opor-se as condições de um moinho de papel. As concretizações abrangem o equipamento de moinho de papel que incorpora uma camada de poliuretano tendo um valor de histerese menor que 70% e um ajuste permanente menor que 30%. A camada de poliuretano inclui um poliuretano produzido por cura de uma composição de mistura. A composição de mistura inclui pelo menos um pré-polímero de uretano (A) e pelo menos um agente de cura (B) tendo um grupo hidrogênio ativo (H). O pré-polímero uretano (A) tem pelo menos um grupo isocianato terminal e é obtido por reação pelo menos um composto de poliisocianato (a) com pelo menos um composto diol policarbonato (b) tendo um número médio do peso molecular de pelo menos 1500 g/mol. O agente de cura (B) inclui pelo menos um composto de amina. As composições elastoméricas são também úteis para revestir o cilindro com o ácido de conservação na indústria do aço.
