Abstract

Inventia se refera la un carton hidrorezistent din fibre celulozice. în scopul reducerii costului el include celuloza sulfat albita din rasinoase, celuloza de bumbac, celuloza sulfit chimica, precum si un agent de hidrorezistenta pe baza de poliamin-poliamid-epiclorhidrina. Procedeul pentru realizarea cartonului consta din destramarea urmata de marirea a fiecarei celuloze componente, amestecarea lor cu introducerea agentului de hidrorezistenta si uscarea prin depunerea pe site uscatoare într-un mediu de aer cald. Se utilizeaza, în special, pentru filtrarea berii.The invention relates to a hydrous-resistant cellulose fiber board. In order to reduce the cost, it includes whitewash white cellulose sulfate, cotton cellulose, chemical sulphite cellulose, and a polyamine-polyamide-epichlorohydrin-based hydroresistant agent. The process for making cardboard consists of the disintegration followed by the growth of each component cellulose, blending with the introduction of the hydrosurface agent and drying by deposition on the drying site in a warm air medium. It is especially used for beer filtration.
