塑料作为一种原料易得、性能优越、加工方便、价格低廉的有机合成材料,在材料领域中占有重要地位。林业生产中集材、装车等采运机械冬季生产所用的机库,长期以来一直是采用原木修建的“木刻楞”。这种机库不仅消耗大量的木材,而且不利于保温、防火。为了改进这种原始、落后的机库造型,广大林业工作者做了很大努力。1981年冬季阿里河林业局首先试制、试用的“塑料机库”经过一个冬季的考验,达到了予期效果,为节约木 Plastic as a raw material is easy to get, superior performance, processing convenience, low prices of organic synthetic materials, plays an important role in the field of materials. In the forestry production, the hangar used for the winter production of collecting, loading, and loading machines has long been a “woodcarving” planted with logs. This hangar not only consumes a lot of wood, but also not conducive to heat preservation, fire prevention. In order to improve this primitive, backward hangar shape, the majority of forestry workers made great efforts. In the winter of 1981, the first trial of the Ali River Forestry Bureau trial, the trial of “plastic hangar” after a winter test, to achieve the desired effect, to save wood
