Manufacture craft for preparing foamed bamboo fiberboard by abandoned concrete block
The invention discloses a manufacture craft for preparing a foamed bamboo fiberboard by abandoned concrete blocks, and belongs to the technical field of concrete block reuse. The craft comprises the following step of treating the concrete blocks: cleaning the concrete blocks, removing impurities and dust on the surface, crushing the concrete blocks repeatedly, and selecting the concrete blocks with the partical size less than 20mm after the screening. By providing the concrete blocks, aldehyde-free adhesive and nanometer expanded graphite in the manufacture craft for preparing the foamed bamboo fiberboard by abandoned concrete blocks, on the one hand, water vapor is enabled to fast run through during use to improve moisture-penetrability of the product, and on the other hand, the structurehas a large angle contact with the water to be of a hydrophobic structure similar to the surface of a lotus leaf to play a waterproof effect, so that the device not only has high support strength, but also is good in waterproof effect, not easy to generate dilatational force difference after water adsorption to make sheets warped, layered or cracked and the like, thereby having high practicability.
本发明公开了一种废弃混凝土块制备泡沫竹纤维板的制作工艺，属于混凝土块再利用技术领域，其包括以下步骤：混凝土块处理，先将混凝土块进行清洗，去除表面的杂质和灰尘，再对其反复进行破碎，筛分后选取粒径小于20mm的混凝土块。该废弃混凝土块制备泡沫竹纤维板的制作工艺，通过设置混凝土块、无醛粘合剂和纳米膨胀石墨，一方面，有利于在使用过程中水蒸气快速通过，提高产品的透湿性，另一方面，此结构与水接触角大，为类似于荷叶表面的一种疏水结构，从而起到防水效果，使得本装置不仅支撑强度较大，而且防水效果较佳，不易因为吸水后产生膨胀力差异而使板材翘曲变形、分层或者爆裂等，使得实用性较高。
