Abstract
Rattan in Indonesia is traditionally utilized for furniture, binding materials, household appliances, and handicraft items. Small diameter rattans are commonly used by craftsmen, while large diameter rattans are not optimally utilized. Large diameter rattan, however, has potential to be developed into rattan laminated board (RLB) by gluing rattan strips using appropriate adhesive. Nevertheless, the information of the suitable natural adhesive for RLB production is still limited. Laboratory scale of RLBs with the dimensions of 60 cm x 7.5 cm x 1.5 cm were manufactured using batang rattan strips (Calamus zollingeri Becc.). The strips were glued with six types of adhesives (4 types of natural adhesives and 2 types of commercial synthetic adhesives) and three glue spread rates of (100, 150, and 200 g/m2) were used. The study objective was to determine the effect of rattan pre-treatments, adhesive types and glue spread rates on the bonding quality and formaldehyde emission of RLBs. The results showed that batang rattan can be processed into RLBs by using natural adhesives originating from wood bark extract (mangium, mahogany), merbau wood powder, as well as commercial synthetic adhesives such as isocyanate and polyurethane. The appropriate pre-treatment in producing RLBs for interior furniture was by applying oil heat treatment with kerosene solution (80 kerosene : 20 water) and glued with tannin adhesive of mangium bark extract with glue spread of 200 g/m2. Similarly, rattan strips treated with heated oil (80 kerosene : 20 water) and glued with polyurethane adhesive (glue spread of 200 g/m2) produced excellent RLBs for exterior furniture.
藤条在印度尼西亚传统上用于家具、装订材料、家用电器和手工艺品。工匠通常使用小直径藤条,而大直径藤条则没有得到最佳利用。然而,通过使用适当的粘合剂粘合藤条,大直径藤有可能发展成为藤层压板(RLB)。然而,用于RLB生产的合适的天然粘合剂的信息仍然有限。使用巴当藤条(Calamus zollingeri Becc.)制造了尺寸为60cm x 7.5cm x 1.5cm的实验室规模的RLB。用六种类型的粘合剂(4种天然粘合剂和2种商用合成粘合剂)粘合藤条,并使用三种胶水涂布率(100、150和200g/m2)。研究目的是确定藤条预处理、粘合剂类型和胶水涂布率对RLBs粘合质量和甲醛释放的影响。结果表明,使用源自树皮提取物(芒果、桃花心木)、紫珠木粉的天然粘合剂,以及异氰酸酯和聚氨酯等商业合成粘合剂,可以将巴塘藤加工成RLBs。生产用于室内家具的RLB的适当预处理是通过用煤油溶液(80煤油:20水)进行油热处理,并用芒果皮提取物的单宁粘合剂以200g/m2的胶涂进行粘合。同样,用热油(80煤油:20水)处理并用聚氨酯粘合剂粘合的藤条(胶水铺展为200 g/m2)产生了用于外部家具的优异RLB。
