摘要
随着人口的增加,对建筑材料,即木材的需求将会增加,从而引发猖獗的非法采伐,这将导致洪水,山体滑坡和全球变暖。为减少木材的使用所做的努力之一是制作石膏复合板。本研究的目的是利用红木废料和贾提木粉作为石膏板填料。研究了将红木、皂角木废锯末作为聚乙烯醇胶粘剂制作石膏顶棚的填充材料,在70℃高温下进行混合压实处理。质量优良,密度值为0.82 g /cm3,吸收量为38.4%,符合SNI 03-2105-2006标准。力学性能:冲击强度(95:5:10)变化为19.014 J/m2,弯曲强度(95:5)变化为395,446 N/m2,断裂强度(95:5:5)变化为1.7758 N/m2。所制石膏板的抗折强度和断裂强度试验结果不符合石膏板规范SNI 03-6384-2000的要求。
PROCESSING OF SAWDOW WASTE OF MAHONI AND JATI WOOD AS A MATERIAL GYPSUM CEILING FILLERS WITH POLIVINYL ADHESIVE ALCOHOL
Along with the increase in population, the need for building materials, namely wood, will increase, thus triggering rampant illegal logging, which will cause floods, landslides, and global warming. One of the efforts made to reduce the use of wood is to make gypsum composite boards. This study aims to utilize mahogany wood waste and jati wood powder as gypsum board fillers. Research has been carried out on processing waste sawdust from mahogany and jati wood as a filling material for making gypsum ceilings with polyvinyl alcohol adhesive by mixing and compacting using a hot compressor at 70o C. Good quality with a density value of 0.82 g /cm3 and absorption capacity of 38.4% complied with SNI 03-2105-2006. Mechanical properties with variations in impact strength (95:5:10) of 19.014 J/m2, flexural strength of variation (95:5) of 395, 446 N/m2, and fracture strength of variation (95:5:5) of 1.7758 N/m2. A Gypsum board was obtained, which did not meet SNI 03-6384-2000 on the gypsum board specification for the results of testing for flexural strength and fracture strength.
