Description

技术领域 FIELD

[0001] 本发明涉及一种新型促进打浆的纤维改性生物酶制剂,主要应用于造纸行业中硫酸盐木浆打浆前的预处理。 [0001] The present invention relates to a biological enzyme modified fibers to promote a new beating, mainly used in the paper industry wood pulp beating sulfate pretreatment. 一种新型促进打浆的纤维改性生物酶制剂 A fiber beaten by Modified promote biological enzyme

背景技术 Background technique

[0002] 造纸工业是我国国民经济的支柱产业之一,传统的造纸工艺对环境的污染严重。 [0002] paper industry is one of the pillar industries of the national economy, serious pollution of the traditional paper-making process on the environment. 随着国家对环境保护力度的增加,我国造纸企业的节能、减排情况获得了一定的改观,一些污染大,生产规模小的企业被关闭。 With the increase of the state's environmental protection efforts, energy saving, emission reduction of China's paper companies get a certain amount of change, a large number of pollution, small scale enterprises were shut down. 2006年初我国出台的国家中长期科学和技术发展规划纲要(2006〜2020年)中重点领域3 (环境)的主题之一就是综合治污与废弃物循环利用。 In early 2006, China issued the national long-term Science and Technology Development Plan (2006~ 2020) in one of the themes (environment) focal area 3 is integrated pollution control and waste recycling. 2010年2月7日,环保部进行了第一次全国污染源普查统计,2007年由造纸行业排放的废水量在我国工业废水中排第一位,其中化学需氧量(C0D)排放量占所有工业的31. 3%, 2012年造纸行业C0D排放量占全国工业总量的35%,因此开展制浆、造纸的清洁生产,减少废水排放非常必要。 February 7, 2010, the ministry conducted the first national pollution census statistics, in 2007 the volume of wastewater discharged by the paper industry ranked first in China's industrial wastewater, which chemical oxygen demand (C0D) emissions account for all 31.3% of the industry, in 2012 the paper industry C0D emissions account for 35% of the country's industrial and therefore carry out clean production of pulp, paper and reduce waste water discharge is necessary. 随着人们要求改善环境、保护森林、节约能源及原材料、降低造纸成本的呼声日益高涨,再加上环保要求越来越严格,造纸原料价格不断上涨和能源压力,造纸企业节能减排引起世界各国政府及企业的重视。 As people required to improve the environment, protect forests, conserve energy and raw materials, reducing paper costs is growing, coupled with increasingly stringent environmental requirements, paper and rising raw material prices and energy pressures, energy conservation cause paper companies around the world the attention of government and business. 造纸企业节能减排可促进造纸工业集中度的提高,促进产业结构调整,有利于向环境友好型、资源节约型的现代化造纸工业的方向发展。 Paper-making enterprises to promote energy conservation can improve the concentration of the paper industry, promote industrial restructuring is conducive to the development of environment-friendly, resource-saving direction of modern paper industry.

[0003] 打浆,是造纸的一个非常重要的工序,打浆需消耗大量的能量,约占从木材到成纸生产总能耗的15%〜18%。 [0003] beating, is a very important process of papermaking, beating consumes a lot of energy, 15% ~ 18% of the total energy consumption in the production of paper from wood to about percent. 占全球化学浆年产量89%的硫酸盐浆,其不易打浆,消耗大量的能量,均耗电量200〜300kWh/t浆,高黏状打浆平均耗电量为250〜500kWh/t浆。 Accounting for 89% of global annual production of chemical pulp kraft pulp, it is not easily beating, a lot of energy, both power consumption 200~300kWh / t pulp, beating-like high viscosity average power consumption of 250~500kWh / t pulp. 降低纸浆特别是硫酸盐浆的打浆能耗,是造纸工业节能减排的一项战略性问题。 Reduce refining energy particular pulp kraft pulp and paper industry is a strategic issue of energy saving. 造纸工业节能有两种途径:从管理方面降低单位产品能耗;利用新技术降低单位产品能耗。 Saving paper industry, there are two ways: reduce energy consumption per unit of product from management; the use of new technology to reduce energy consumption per unit of product. 同时,随着商品浆价格的上涨和纸产品价格的涨幅较小,纸产品利润空间缩减,部分造纸企业生存越来越困难,只能通过采购相对低廉的国产浆料代替进口浆料,为企业创造利润,但使用国产浆料存在强度比进口浆料差、造成成纸强度下降的风险,尤其是对铜版纸强度的影响。 Meanwhile, with a smaller market pulp prices and paper product prices rise, profit margins reduced paper products, business survival increasingly difficult section of the paper, can replace imported slurry through the procurement of relatively low domestic pulp for enterprises to create profits, but there is the use of domestic pulp slurry intensity difference than imports, the risk of falling into the paper strength, especially on coated paper strength. 因为部分铜版纸印刷后折页爆裂问题一直成为大、中型铜版纸生产企业急需解决的难题,如果生产浆料强度再变差,那问题将更加严重。 Because after folding burst problem has been a big part of the coated paper printing, coated paper and medium-sized enterprises need to solve the problem, if the production of pulp strength deteriorate again, the problem will become more serious. 在国内更多大型铜版纸纸机投产释放产能的当今, 如何在保证纸产品利润的同时保证或提高铜版纸的质量成为各大造纸企业的重中之重。 In China more large-scale production of coated paper machine production release today, how to ensure or improve the quality of coated paper in the paper products to ensure profits at the same time become the top priority of the major paper companies.

[0004] 现工艺中,打浆能耗的节省从设备和流程上的优化空间极小。 [0004] The current process, refining energy savings from a very small space on the device and the optimization process. 纸张的强度多通过化学增强剂改善和提高,但效果有限,成本极高,还会带来纸机运行和纸张其他方面问题, 如表面印刷性能、阴离子垃圾等等。 Strength of the paper and more by chemical enhancers to improve and increase, but the effect is limited, high cost, but also bring paper machine operation and other aspects, such as surface printing performance, anionic trash and so on. 因此通过更清洁、节能、环保的生物技术整体提升造纸行业技术水平,改变高能耗高污染的形像势在必行。 Therefore, through cleaner, energy-saving, environmental protection and biotechnology to enhance the overall technological level of the paper industry, it is imperative to change the image of high energy consumption and high pollution.

[0005] 生物技术受到更多的关注,因为它可以减少对环境的破坏、节约能源、提高产品质量。 [0005] Biotechnology receive more attention, because it can reduce damage to the environment, save energy, improve product quality. 与一般非生物催化剂相比,酶具有温和性、专一性、高效性和可调性等特点。 Compared with the general non-biological catalysts, enzymes have mildness, specificity, efficiency and adjustability features. 通过酶预处理可以改善纸浆纤维,降低打浆能耗,还有可能提高纸浆的滤水性能及成纸质量。 Enzymatic pretreatment can be improved by the pulp fibers, reducing refining energy, it is also possible to improve the drainability of the pulp and paper quality. 生物酶在造纸上的应用技术越来越成熟,其中新型促进打浆的纤维改性生物酶制剂,除了以往大家熟知的是其降低磨浆能耗方面的作用外,如何利用新型促进打浆的纤维改性生物酶制剂提高成纸强度,已被许多致力于造纸生物酶的人士所关注。 Application of the enzyme in a more mature papermaking, which facilitate beating of the fiber modified novel enzyme preparations, in addition to the conventional well-known effect of which is to reduce the refining energy consumption, the promotion of how to use the new refined fiber change biological enzymes to increase paper strength, has been of concern to many people committed to paper biological enzymes.
