Abstract
The Larch was known unsuitable species for the wood cement board owing to its some inhibitory substances. Therefore this research was carried out to evaluate the effect of pretreatments and chemical additives on the properties of woodflake cement board from Japanese larch (Larix leptolepis) grown in Korea. In order to improve the board qualities, the woodflakes were treated by cold water or dilute NaOH solutions(0.1, 0.5, and 2.0%), and also some chemicals(
낙엽송(落葉松)은 몇가지의 세멘트경화장해물질(硬化障害物質)을 함유(含有)하고 있기 때문에 목질(木質)세멘트판(板)의 제조(製造)에 부적합(不適合)한 수종(樹種)으로 알려져 왔다. 따라서 본(本) 연구(硏究)는 국산(國産) 낙엽송재(落葉松材)의 플레이크를 이용(利用)한 목질(木質)세멘트판(板) 재질(材質)에 미치는 전처리(前處理) 및 첨가제(添加劑)의 효과(效果)를 구명(究明)하고자 실시(實施)되었다. 보드의 재질(材質)을 향상(向上)시키기 위(爲)하여 냉수처리(冷水處理) 및 0.1, 0.5, 2.0%NaOH 용액(溶液)에 원료(原料)flake를 전처리(前處理) 시켰으며,
