高强高模聚乙烯醇(PVA)纤维是有害建筑材料石棉的替代品,每吨高强高模PVA纤维能替代6吨石棉。作为高强高模PVA纤维原料PVA本身无毒,如其深加工可作食品添加剂、人造肠及医用缝合线等,加工后纤维不会产生粉尘吸入人的肺部,同时纤维极限氧指数高,不易燃烧,燃烧后不会产生有毒气体,因此被誉为“绿色环保产品”。同时,该纤维又是纤维混凝土中最具有发展前景的纤维掺加物。该产品的生产具有优化人类生存环境,增加企业的经济效益和社会效益的重大意义,完全符合国家大力鼓
High-strength high-modulus polyvinyl alcohol (PVA) fiber is a harmful substitute for asbestos for building materials, and can replace 6 tons of asbestos per ton of high-strength and high-modulus PVA fiber. PVA as a high strength and high modulus PVA fiber itself is non-toxic, such as its deep processing can be used as food additives, artificial intestines and medical sutures and other fibers will not produce dust inhaled after the lungs, while the fiber limit oxygen index is high, After burning does not produce toxic gases, it is known as “green products ”. At the same time, the fiber is the most promising fiber admixture in fiber concrete. The production of this product has the great significance of optimizing human survival environment and increasing the economic and social benefits of the enterprise and is in full compliance with the requirements of the State
