Description

家具用竹材的防霉处理方法
技术领域
本发明涉及家具用的竹制品，尤其涉及家具用竹材的防霉处理方法。
背景技术
自古以来人类就喜欢用木材和竹材来装点室内环境和制作室内家具。因此，实木家具和圆竹家具历史悠久，源远流长，直至现代仍为人们所喜爱。竹集成材家具是近几年开发出来的新生竹家具，因其材料具有大自然赋予的独特美感以及优越的材料特性，并具有生态性和环保性而为国内外，特别为环保意识较强的欧美发达国家所青睐。
竹子具有繁殖容易，生长快，成材早，产量高，具有一次造林成功,可年年择伐，永续利用而不破坏生态环境的特点。由于竹材结构和化学组成都和木材有很大差异，其强度和密度都高于一般木材，竹材产品的强度大于一般木材产品,因此可用较小厚度的竹材产品替代较大厚度的木材产品，以取得经济上的优势。竹材纹理通直，质感爽滑，色泽简洁，易于漂白、染色和炭化等处理，完全可以和一些阔叶材相媲美，是生产集成材的优质材料。
竹子主要是由纤维素、半纤维素、木质素、糖类等化学成分组成，这些都是蛀虫、细菌的好饲料，所以竹制家具易生虫、生霉，因此做为家具用的竹材，必须要经过三防处理，即防腐、防虫和防蛀。
发明内容
基于上述问题，本发明公开一种家具用竹材的防霉处理方法，方法简单，且不产生废水，所得竹材即防霉，同时也进行了漂白处理。
本发明所采用的技术方案如下：
家具用竹材的防霉处理方法，
步骤1：除糖，采用碱处理法对竹材进行除糖处理，将竹材浸泡在浓度为1.25％NaOH溶液中，温度80-90℃，浸泡时间30分钟以上，不超过60分钟；
步骤2：脱色氧化，用浓度为1-1.5％的过氧过氢，水温保持在60-70℃，PH值10-11，浸泡4-6小时，浸泡过程中，加一次稳定剂；
步骤3：中和，溶液采用浓度为0.5％的Na2S2O4，溶液的PH值5-6，浸泡时间为5-7小时；
步骤4：烘干，烘干房温度为50-70℃，烘3-5小时。
稳定剂为焦磷酸钠。
本发明处理方法简单，除糖，可有效的除去竹材中的糖类和蛋白质，在碱溶液中能浸提出来，使处理后的竹材不易霉变；脱色氧化，利用过氧化氢的氧化作用，对竹材进行脱色，由于过氧化氢不稳定，因此加入一定的稳定剂，以控制反应速度；氧化后的竹材还残留有部分过氧化氢，利用二亚硫酸钠溶液，来中和残留的过氧化氢，最后烘干，处理后的竹材外观质量也改善，增进了竹制品的美观，也同时解决了竹材的霉变和虫蛀问题。
具体实施方式
以下详细描述本发明的技术方案。本发明实施例仅供说明具体结构，该结构的规模不受实施例的限制。
家具用竹材的防霉处理方法，
步骤1：除糖，采用碱处理法对竹材进行除糖处理，将竹材浸泡在浓度为1.25％NaOH溶液中，温度80-90℃，浸泡时间30分钟以上，不超过60分钟；
步骤2：脱色氧化，用浓度为1-1.5％的过氧过氢，水温保持在60-70℃，PH值10-11，浸泡4-6小时，浸泡过程中，加一次稳定剂焦磷酸钠。；
步骤3：中和，溶液采用浓度为0.5％的Na2S2O4，溶液的PH值5-6，浸泡时间为5-7小时；
步骤4：烘干，烘干房温度为50-70℃，烘3-5小时。
