【摘要】：本研究以速生杨木和速生杉木为对象,对这两种材质较差的速生木材用于制造高档室内装饰材料的生产工艺进行了研究,希望探索一条以利用速生工业林为主的低质木材逐步取代天然林而用于木材深加工和创造高附加值产品的新用途,提升传统产业、开拓新的市场。此研究符合国家林业发展政策。本课题在研究中分别就现有的生产工艺进行了分析,通过对杨木的变形、杨木的蓝变、指接耗材过大、异型截面工件腻子涂布与砂光困难、杉木年轮膨胀、杉木树节油脂渗透、底层透色、涂层(腻子)气泡、腻子附着力差等生产中的具体问题进行了探讨,进行了大量的试验,优选出的以0.50%百菌清+0.30%硼酸+0.30%94消毒液为主要原料的杨木防蓝变剂,能有效地防止速生杨木的快速蓝变。通过采用自然干燥降低速生杨木的初含水率、提高窑内循环风速、提高介质温度、合理选择循环风向、高温水汽预热、将传统窑体进行适当的改造以提高热效率等措施,在保证干燥质量的情况下,将速生杨木的干燥周期缩短了3天。同时,针对装饰线材截面变化大而难于填刮腻子的特点以及速生木材涂层易出现气泡、脱落、透色、膨胀变形的特点,提出了直线异型截面涂装与涂层气泡消除技术、水性腻子的快速干燥技术、防止杉木年轮膨胀技术、杉木抽提物渗透的处理技术、热量循环与综合利用技术以及减少木质原材料的消耗的新的生产工艺与技术,此外,还通过对杨木和杉木的材质特性的分析,提出了有效解决腻子附着力差的方法。通过本课题的研究,总结出了一套利用速生木材制造高档室内装饰材料的新工艺,成功地解决了速生杉、杨木制造线型室内装饰材料中所遇到的各种技术问题,不仅降低了生产成本,提高了产品质量和产能,而且使得速生木材制造高档装饰材料的生产工艺更加合理,真正实行了工业化生产。此套工艺和方案,通过在工厂的实际应用,取得了良好的效果,按照此工艺生产的产品全部出口到美国和加拿大,经过严格检验,产品百分之百合格,同时,本课题的部分研究结果己在国内有关专业杂志上公开发表。
[Abstract]:In this study, fast growing poplar and fast growing Chinese fir were taken as the objects to study the production technology of these two kinds of fast growing wood, which were used to manufacture high grade interior decoration materials. It is hoped to explore a new use of low-quality wood, which mainly uses fast-growing industrial forest, to replace natural forest for deep processing of wood and to create high value-added products, to promote traditional industries and to open up new markets. This study is in line with the national forestry development policy. In the research of this subject, the existing production technology is analyzed, through the deformation of poplar, the blue change of poplar, the excessive consumption material of finger joint, the difficulty of coating and sanding of special section workpiece putty, the expansion of annual ring of Chinese fir, the penetration of oil and grease of Chinese fir node, The specific problems in the production of underlayer percolation, coating (putty) bubble and poor adhesion of putty were discussed. A large number of experiments were carried out, and 0.50% chlorothalonil 0.30% boric acid 0.30% disinfectant was selected as the main raw material of poplar anti-blue change agent, and the main raw material was 0.50% chlorothalonil 0.30% boric acid 0.30% disinfectant. Can effectively prevent fast growing poplar rapid blue change. By using natural drying to reduce the initial moisture content of fast-growing poplar, to increase the circulating wind speed, to raise the temperature of the medium, to select the circulation wind direction reasonably, to preheat the water vapor at high temperature, and to improve the thermal efficiency of the traditional kiln body by proper modification, etc. Under the condition of ensuring drying quality, the drying period of fast growing poplar was shortened by 3 days. At the same time, aiming at the characteristics that the cross section of decorative wire is changed greatly, it is difficult to fill the putty, and that the rapid growing wood coating is easy to appear bubble, shedding, color permeation and swelling deformation, the technology of coating and bubble elimination of the coating is put forward. Waterborne putty rapid drying technology, preventing Chinese fir annual ring expansion technology, Chinese fir extract infiltration treatment technology, heat circulation and comprehensive utilization technology and reduce the consumption of wood raw materials new production technology and technology, in addition, Through the analysis of the material properties of poplar and Chinese fir, an effective method to solve the poor adhesion of putty is put forward. Through the research of this subject, a set of new technology of making high-grade interior decoration materials by using fast-growing wood is summarized, and the various technical problems encountered in the manufacture of linear interior decoration materials by fast-growing wood and poplar are solved successfully. It not only reduces the production cost, improves the product quality and production capacity, but also makes the production process of the high-grade decorative material of fast-growing wood more reasonable, and the industrialized production is really carried out. Through the practical application in the factory, this set of processes and schemes have achieved good results. All the products produced according to this process have been exported to the United States and Canada. After strict inspection, the products are 100% qualified, and at the same time, Some of the research results of this topic have been published in the relevant professional journals in China.
