LF-39 pulp fast solvent
热充程序时添加的辅助助剂。 LF-39 type fast dissolving agent special for dissolving pulp is a kind of auxiliary additive developed by our company to be used in the hot charging process after pre-hydrolysis of dissolving pulp . 中预水解酸液，能快速渗透和置换，在快速蒸煮中，可以有效提高蒸煮 的均匀性，特别是对原料大小、密质度、形状等差别较大的情况下，尤 其有效；提高药液反映效果，加速溶出更多的多戊糖、木素及杂质；确 保蒸煮的均匀性，减少残渣，提高得率，最终提高产品。 For the lye is difficult to penetrate after the pre-hydrolysis, it is difficult to displace the pre-hydrolyzed acid solution in the raw material tablet , which can quickly penetrate and replace. In the rapid cooking, it can effectively improve the uniformity of cooking , especially for the size, density, shape, etc. It is especially effective in the case of large differences ; it improves the reflection effect of the medicinal solution and accelerates the dissolution of more polypentose, lignin and impurities; ensures the uniformity of cooking, reduces residue, improves yield, and ultimately improves the product.
力，从而能快速渗透到原料的内部，置换出预水解残留在原料内部的预 水解液，有利于药液快速渗透、湿润、分散，容易加入到原料和纤维细 胞壁内多戊糖溶出，有效地促进胞层间木素的脱除和细胞壁中歼余木素 的脱除，使得纸浆木素更彻底。 LF-37 has a high active gene group, which can reduce the surface tension of the medicinal solution during the reaction of the medicinal solution , so that it can quickly penetrate into the interior of the raw material, replacing the prehydrolyzed solution remaining in the interior of the raw material , which is beneficial to The medicinal solution quickly penetrates, wets, and disperses, and is easily added to the raw materials and the dissolution of polypentose in the cell wall of the fiber , which effectively promotes the removal of interstitial lignin and the removal of residual lignin in the cell wall , making pulp lignin more thorough . 匀性。 Reduce the content of lignin and other magazines and improve the cooking uniformity . 团发生反应，提高原浆白度，改善纸浆的洗涤性和漂白性。 Residues are reduced and yield is increased. Active groups selectively react with chromogenic gene groups in the pulp to increase the whiteness of the pulp and improve the washing and bleaching properties of the pulp. 残液中碱的浓度，有利于碱回收，对环境友好。 It can increase the concentration of alkali in the cooking residue, is beneficial to the recovery of alkali, and is environmentally friendly. 窄，提高溶解浆质量。 The distribution of the degree of polymerization of the slurry is narrowed , and the quality of the dissolved slurry is improved.
