颗粒木质素纤维简介

Introduction of granule lignin fiber

目前市场上的颗粒木质素纤维主要分为两大类:一类是采用蜡作为造粒剂，缺点是颗粒较硬很难分散，且蜡对沥青混合料本身就有害，在实际使用中往往在沥青混合料中会发现有未分散的颗粒纤维;另一类是用沥青作为造粒剂，制造出来的颗粒木质素纤维容易分散，克服了在生产中难以分散的缺点，同时造粒剂本身对沥青混合料无害。据了解，国内道路市场上应用较多的颗粒木质素纤维是进口的某进口品牌公司生产的V某系列产品，造粒剂采用对沥青混合料无害的德国重交沥青，原料则完全采用某进口品牌公司自己生产的松散木质素纤维，由于V某产品是在每根纤维表面均匀涂抹上一层沥青，并且沥青未浸透纤维，然后再制作成颗粒状，成品的颗粒状纤维中约含10%的沥青，因此V某颗粒在沥青混合料拌和过程中纤维表面的沥青涂层受热易于融化，其中的木质素纤维可以迅速分散在混合料中并吸附沥青，达到稳定沥青混合料的效果。该松散木质素纤维原材料以天然木材为主，采用物理过程加工后从天然木材中提取出特级纤维素，颜色为灰色，主要制作流程为:天然原木→机械粉碎→烘干→机械研磨→分离→木质素纤维→包装

Currently on the market of particulate wood fiber is mainly divided into two categories: one is using wax as a granulating agent, the disadvantage is hard particles are dispersed, and the wax on the asphalt mixture itself is harmful, in actual use, often in the asphalt mixture will be found to have fiber dispersed particles without the other; one is using asphalt as granulation agent, wood fiber particles produced easily dispersed, in production to overcome the scattered shortcomings, at the same time granulating agent on asphalt mixture itself is harmless. It is understood that the particulate wood application more domestic road market on the fiber is imported in an imported production of Brand Company V a series of products, granulating agent on asphalt mixture using harmless German heavy traffic asphalt materials, complete with imported Brand Company's own production of loose wood fiber quality, because a product is on the surface of V each fiber evenly coated with a layer of asphalt and asphalt not soaked fiber, then made into granular, granular fiber product contained about 10% of asphalt, therefore V particles in asphalt mixing process of asphalt coating on the surface of the fiber is easy to melt, which the lignin fiber can be quickly dispersed in the mixture. And to achieve stable adsorption of asphalt, asphalt mixture effect. The loose lignin fiber raw materials in natural wood, the physical process of processing from natural wood extract superfine cellulose, grey color, the main production processes: natural wood, mechanical crushing, drying, grinding, separation, lignin fiber and packaging
