Abstract

"SISTEMA DE MICROPARTìCULAS USADO COMO UM AUXILIAR DE RETENçãO E DRENAGEM EM UMA MASSA DE PAPEL, PRODUTO DE PAPEL, E, PROCESSO PARA PRODUçãO DO MESMO" Um sistema de micropartículas para uso como auxiliar de retenção e drenagem na produção de produtos de papel ácidos e alcalinos compreende um polímero floculante HMW (6), um colóide ácido (7), e um coagulante ou floculante MMW (5). O colóide ácido (7) compreende uma solução aquosa de um polímero ou copolímero solúvel em água de melamina aldeído, preferivelmente melamina formaldeído, e está presente em um montante na faixa de 0,0005% a 0,5% em peso com base no peso seco dos sólidos na massa. O polímero floculante HMW (6) pode ser adicionado à massa após a bomba de palhetas, e antes de peneira sob pressão (2); o colóide ácido (7) pode ser adicionado à massa após a peneira sob pressão (2), e o coagulante/floculante MMW (5) pode ser adicionado antes da bomba de palhetas (1). Alternativamente, esta seq³ência de adições químicas pode ser alterada, isto é, o colóide ácido (7) pode ser adicionado antes ou depois da bomba de palhetas (1) ou antes da peneira sob pressão (2). Adição do sistema de micropartículas à massa de papel melhora a retenção, drenagem e formação de folha durante o processo de fabricação do papel."MICROPARTICLE SYSTEM USED AS A RETENTION AND DRAINAGE AID IN A PAPER MASS, PAPER PRODUCT, AND, PROCESS FOR THE PRODUCTION OF THE SAME" A microparticle system for use as a retention and drainage aid in the production of acidic and paper products alkalis comprise an HMW flocculating polymer (6), an acidic colloid (7), and an MMW coagulant or flocculant (5). The acid colloid (7) comprises an aqueous solution of a water soluble polymer or copolymer of aldehyde melamine, preferably melamine formaldehyde, and is present in an amount ranging from 0.0005% to 0.5% by weight based on weight dry solids in the mass. The HMW flocculating polymer (6) can be added to the mass after the vane pump, and before a pressure sieve (2); the acid colloid (7) can be added to the dough after the pressure sieve (2), and the MMW coagulant / flocculant (5) can be added before the vane pump (1). Alternatively, this sequence of chemical additions can be altered, that is, the acid colloid (7) can be added before or after the vane pump (1) or before the pressure screen (2). Addition of the microparticle system to the paper mass improves retention, drainage and sheet formation during the papermaking process.
