Abstract

一种竹片加工方法，包括以下步骤：S1.采用含水率在50％左右的新鲜圆竹打通内节，用刮青机削去竹筒的竹青，在所述竹筒上开设出一个轴向缝隙；S2.采用微波加热的方法将所述竹筒升温至100～120℃左右进行软化、灭菌和脱脂；本发明实施例中，该方法首先将竹材进行软化展开成型、脱脂，然后采用两次碳，炭化过程中使竹材中的有机物如糖、淀粉、蛋白质等在高温、高湿的环境下分解，使真菌等虫类失去营养来源，同时又将附着在竹材中的虫卵及真菌杀死，防霉防蛀的效果好，且保证了竹片在成产品后不易发生变形，具有良好的物理性质。

Description

一种竹片加工方法
技术领域
本发明涉及一种材料加工领域，尤其涉及一种竹片加工方法。
背景技术
在现有技术中，竹子作为一种常见的植物，在工业应用中具有非常广阔的应用价值，特别是将竹子进行处理后，可以制成家具、地板、用具等多种产品，相对于木制品来说具有价格低廉、重量较轻、材料来源广泛等多重优点，但是，竹片由于自身特性，其防霉防蛀处理在竹制品加工行业中非常重要，目前，现有技术中一般通过一次碳化、干燥以及热压工艺，从而达到防霉防蛀的目的，但是这样的工艺不够完善，防霉防蛀效果一般。
此外，现有竹材的使用，都是采用新鲜毛竹运至加工现场加工、挑选，竹材利用率低，且运输费用大。竹材因其生长条件与特性，其材质普遍存在不同程度的弯曲与变形，而且容易虫蛀，在做好的竹凉亭、竹篱笆使用 3 年后就需现场灭菌，使用寿命低，维护和加工成本较高，制约了竹材的使用。
发明内容
针对现有技术中的缺点和不足，通过微波加热、灭菌、脱脂、软化后碾压整形的加工方法，提高竹才利用率与使用年限，降低成本。
本发明的目的是通过以下技术方案实现的 ：
一种竹片加工方法，包括以下步骤 ：
S1. 采用含水率在 50％左右的新鲜圆竹打通内节，用刮青机削去竹筒的竹青，在 所述竹筒上开设出一个轴向缝隙 ；
S2. 采用微波加热的方法将所述竹筒升温至 100 ～ 120℃左右进行软化、灭菌和脱脂 ；
S3. 将软化后的竹筒展开形成竹片，将竹片粗铣，然后将经过粗铣后的竹片进行碾 压并风冷至 30℃定形 ；
S4.进行碳化，碳化先将竹片在 110℃～ 125℃的微波下进行碳化，时间为 2 ～ 2.5小时，然后升温至 130 ～ 135℃，时间为 1 ～ 1.5 小时。
优选地，在 S3 和 S4 之间还包括竹片烘干步骤，将定型后的竹片放入烘干设备中， 脱水至竹片含水率达到 10％～ 13％时取出，将脱水后的竹片用高压喷沙清洗竹材表面。
优选地，S2 步骤中的灭菌方法为，将竹片置于浓度为 75％的乙醇溶液中密闭浸泡 30 分钟。
与现有技术相比，本发明实施例至少具有以下优点 ：
本发明实施例中，该方法首先将竹材进行软化展开成型、脱脂，然后采用两次碳，将竹片放置在乙醇溶液中进行浸泡，从而以化学方法破坏竹片中的有机物，炭化过程中 使竹材中的有机物如糖、淀粉、蛋白质等在高温、高湿的环境下分解，使真菌等虫类失去营 养来源，同时又将附着在竹材中的虫卵及真菌杀死，防霉防蛀的效果好，且保证了竹片在 成产品后不易发生变形，具有良好的物理性质。
具体实施方式
下面结合实施例对本发明作进一步详述，以下实施例只是描述性的，不是限定性的，不能以此限定本发明的保护范围。
一种竹片加工方法，包括以下步骤 ：
S1. 采用含水率在 50％左右的新鲜圆竹打通内节，用刮青机削去竹筒的竹青，在所述竹筒上开设出一个轴向缝隙 ；
S2. 采用微波加热的方法将所述竹筒升温至 100 ～ 120℃左右进行软化、灭菌和脱脂 ；
S3. 将软化后的竹筒展开形成竹片，将竹片粗铣，然后将经过粗铣后的竹片进行碾 压并风冷至 30℃定形 ；
S4.进行碳化，碳化先将竹片在 110℃～ 125℃的微波下进行碳化，时间为 2 ～ 2.5小时，然后升温至 130 ～ 135℃，时间为 1 ～ 1.5 小时。
在 S3 和 S4 之间还包括竹片烘干步骤，将定型后的竹片放入烘干设备中，脱水至竹 片含水率达到 10％～ 13％时取出，将脱水后的竹片用高压喷沙清洗竹材表面。
S2 步骤中的灭菌方法为，将竹片置于浓度为 75％的乙醇溶液中密闭浸泡 30 分钟。
以上所述，仅为本发明较佳的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应该以权利要求书的保护范围为准。
