Description
Изобретение относитс к целлюлозно-бумажной промышленности и промышленности строительных материалов, а именно к волокнистой массе дл кровельного картона-основы рубероида, пергамина и др.The invention relates to the pulp and paper industry and the building materials industry, namely to pulp for roofing paperboard base of roofing material, glassine and others.
Известна масса дл кровельного картонаосновы , включаюш,а тр пичную полумассу, макулатуру и волокно.The known mass for roofing paperboard is inclusive, and the trout is half-mass, waste paper and fiber.
Целью изобретени вл етс улучшение качества картона и расширение сырьевой базы дл производства кровельных материалов.The aim of the invention is to improve the quality of cardboard and the expansion of raw materials for the production of roofing materials.
Это достигаетс тем, что волокниста масса в качестве волокна содержит полуцеллюлозу из гузапаи, полученную при рН раствора 4-9, в следуюш,ем соотношении компонентов , вес. %:This is achieved by the fact that the fibrous mass as fiber contains guzapai hemicellulose, obtained at a pH of 4–9, in the following ratio of components, wt. %:
Таблица ITable I
Как видно из таблиц кровельный картоноснова с предложенной композицией отвечает требовани м ГОСТа.As can be seen from the tables, the roofing cardboard with the proposed composition meets the requirements of GOST.
