Description
Изобретение относитс к целлюлозно-бумажной промышленности и касаетс волокнистой массы дл изготовлени бумаги.This invention relates to the pulp and paper industry and relates to pulp for making paper.
Известна аналогична масса на основе смеси целлюлозы хвойной и лиственной древесины, например осины. Известна и сульфитаа целлюлоза из хвойной древесины. Така волокниста масса обладает высокой себестоимостью, так как на ее изготовление используетс дорогосто ща сульфитна целлюлоза из хвойной древесины.A similar mass is known based on a mixture of softwood and hardwood pulp, such as aspen. Sulfite pulp from coniferous wood is also known. Such a pulp has a high cost, since its production uses expensive coniferous sulphite pulp.
Дл обеспечени механической прочности бумаги при одновременном удешевлении ее производства предложено в волокнистую массу включать сульфитную целлюлозу из древесины граба. Волокниста масса может содержать 100% сульфитной целлюлозы из древесины граба или смесь сульфитной целлюлозы из древесины граба и сульфитной целлюлозы из хвойной древесины в любом соотношении.To ensure the mechanical strength of the paper while at the same time reducing the cost of its production, it has been proposed to include hornbeam sulphite pulp in the pulp. The fibrous mass may contain 100% hornbeam sulphite pulp or a mixture of hornbeam sulphite pulp and softwood sulphite pulp in any ratio.
BOM основании, и 65% сульфитной целлюлозы из хвойной древесины.BOM base, and 65% softwood sulphite pulp.
Сравнительнал характеристика бумаги I , полученной из волокшютой массы, состав которой приведен выше, и бумаги II, полученнсж из известного состава волокнистой массы, а именно , содержащей 100% хвойной целлюлозы 9095-59) приведена в таблице.Сорность , количество соринок на 1 мComparative characteristic of paper I, obtained from the pulp mass, the composition of which is given above, and paper II, obtained from a known composition of the fibrous mass, namely, containing 100% softwood pulp 9095-59) is shown in the table.
