摘要
中国是竹资源大国,发展竹材工业化是解决目前木材供应缺口的重要途径。但是竹材中含有丰富的营养物质,在保存和使用中很容易发生腐朽、霉变和虫蛀等,研究竹材防霉防腐技术对于高效开发竹材资源具有十分重要的意义。
     本论文以辗压竹束为试验材料,以黑曲霉、绿色木霉和橘青霉为主要霉菌菌种,以白腐菌和褐腐菌为腐朽菌菌种,采用五种环境友好型水溶性防腐剂对碾压竹束进行防腐处理,压制重组竹材,进行性能测试,综合分析筛选出适合于户外重组竹材使用的竹材防腐剂。并进行了辗压竹束防腐处理工艺和重组竹材生产工艺的优化研究,最后进行了验证试验,并在生产线上成功进行了中试,开发出了综合性能优异的户外家具用防腐重组竹材。本研究的结果归纳如下:
     1、采用五种防腐剂处理重组竹材,同时与未防腐处理重组竹材进行对比,进行防腐剂筛选试验,结果证明:经过处理的重组竹材物理力学性能远远高于标准要求,重组竹本身具有天然耐腐性,未防腐处理重组竹材和五种防腐剂处理重组竹材重量损失率均在11%以下,均达到Ⅰ级强耐腐,其中重组竹材对褐腐菌的耐腐性高于对白腐菌的耐腐性,白腐菌失重率为10.11%,而对褐腐菌的失重率只有6.84%。但未防腐处理重组竹材防霉性能较差,一周时间内就出现白色菌丝,28天后全部发霉,五种防腐剂处理重组竹材防霉性能有明显改善。综合考虑到防腐剂价格、抗流失性能等因素,ZJFC-Ⅰ防腐剂的综合性能最好。
     2、采用正交试验对碾压竹束进行防腐处理工艺优化,以防霉效力为指标,分别考察了防腐剂浓度、加压压力和加压时间对防腐处理的影响。结果表明,防腐剂浓度是影响防腐效力最显著的因素,其次为加压压力,加压时间对其影响最小。竹束防腐处理最优工艺为:防腐剂浓度0.8%、加压压力1.2MPa、加压时间4h,在此条件下,防霉效力达到92.33%。
     3、采用正交试验进行防腐处理后的碾压竹束压制重组竹材生产工艺的优化研究,考察了重组竹材密度、浸胶时间和酚醛树脂固体含量的影响。结果表明,重组竹材密度对其影响最大,其次为酚醛树脂固体含量,浸胶时间影响最小。最佳生产工艺为重组竹材密度1.1g/cm3、浸胶时间为30min、酚醛树脂固体含量28%。冷压后竹方需要固化定型处理,处理条件为升温区为100℃,时间为120min;高温区温度135℃,时间120min;保温区温度125℃,180min;降温区80℃,时间60min。
     4、小试及中试证明了应用ZJFC-Ⅰ防腐剂压制户外家具用防腐重组竹材可行,压制的重组竹材具有良好的物理力学性能、加工性能、表面装饰性能和防腐防霉性能。户外防腐重组竹材有着非常广阔的发展空间,拓展了竹材的应用领域,具有很好的环境效益和经济效益。
China is abundant in bamboo resources. Developing bamboo- processing industry is an important approach of solving wood supply gap currently. As bamboo is rich in nutrients, it is liable to rot, mildew, infesting and so on in the preservation and use. A study of anti-corrosion and anti-mildew technique has very important significance to develop bamboo resources efficiently.
     In this paper, we chose pressed bamboo strip as the material. Three kinds of mould fungi and two kinds of decay fungi were used as main harmful bacteria. In order to choose the appropriate preservative for recombination bamboo timber of outdoor furniture, the pressed bamboo strip was treated by five environment-friendly water-borne preservatives and then tested the properties. On the basis of this, this paper studied preservation and production process of outdoor strand recombination bamboo timber. Then the verification was tested, and this process was used in the pilot test successfully. A good comprehensive anti-corrosion recombination bamboo timber used in outdoor furniture was developed. The results of this study are summarized as below.
     1、Five preservatives were used on the pressed bamboo compared with the untreated group. The result showed that the physical and mechanical properties of the pressed bamboo were higher than the standard. Reconstituted bamboo itself has natural decay resistance. The loss rate of the five preservatives group and the untreated group were all below 11%, which reached the high anti decay level.The decay resistance of reconstituted bamboo on brown-rot fungi was higher than on white-rot fungi. The weight lose rate of white-rot was 10.11%, while that of brown-rot was 6.84%. The decay resistance of the untreated group was weak, which appeared white mycelium on the surface of the raw materials in a week and mildewed in 28 days. The decay resistance of reconstituted bamboo by the five preservatives were improved significantly.
     Considering the price of preservatives, leach resistance and other factors, the comprehensive properties of ZJFC-Ⅰwas the best one. Therefore, we chooses ZJFC-Ⅰas the preservative in the production of the outdoor recombination bamboo timber.
     2、Orthogonal experimental was adopted to obtain the reasonable vacuum-pressure in the preservative-treated process the bamboo. Based on the anti-mold effectiveness, the effect factors were investigated, including the preservative concentration, molding pressure and pressing time. The result showed that the concentration of preservative was the important factor in influence the bamboo preservative retention, then the molding pressure and the pressing time. The optimal choice of preservation process was:preservative concentration was 0.8%, molding pressure was 1.2MPa, and pressing time was 4h.Under these conditions, anti-mold effectiveness was 92.33%.
     3、Orthogonal experimental was adopted to obtain the reasonable production process. The effect factors were investigated, including density of the timber, the time of impregnation and glue strength. The result showed the density of the timber was the important factor, then glue strength and the time of impregnation. The optimal choice of production process was:density of the timber was 1.1 g/cm3, the time of impregnation was 30 min and glue strength was 28%.
     It was need to solidifying stereotypes after the cold-press process. There are four stages in the process. It was under the temperature of 100℃continuing 120 min,then 135℃continuing 120min,then 125℃continuing 180min,and then 80℃continuing 60min.
     4、It was possible to use ZJFC-Ⅰin the production of outdoor recombination bamboo furniture by experiment in laboratory and factory.Good physical and mechanical properties, well processing properties, excellent surface decoration properties, anti-mildew and anticorrosive properties were found in the timber. The research of outdoor recombination bamboo timber had wide space for development and expanded application fields of bamboo and created good environmental and economic benefits.
