论胶合板生产中薄板比例及其对经济效益的影响

RATE OF THIN PLYWOOD IN MANUFACTURE AND ITS EFFECT ON ECONOMIC BENEFIT

文中定量给出了薄板率与厚板率、厚板和薄板及中板的平均厚度、1830mm(6英尺)长木段的所占比例、每立方米1830mm长木段所出的面背板张数的关系等。指出了一个企业生产薄板能力的测算办法。薄板率不是一个科学的技术指标,而应代之以每立方米胶合板平均张数。应尽量加大长木段的比例,生产规格以915mm×1830mm(3′× 6′)为主,如材质允许则以1220mm×2440mm(4′×8′)为主,可以获得最高的薄板比例;应开发厚板市场,生产一定比例的厚板也有利于薄板比例的提高。还论述了薄板率变化对经济效益的影响。

Quantitatively we have obtained the rate of plywood of thin and thick, the average thickness of plywood of thin. medium and thick, rate of length of 1830 mm log, the sheets of face and back veneer that per cubic meter timber of 1830 mm can make etc. It gives a measure of testing the capability that how much thin plywood a factory can manufactured. The rate of thin plywood is not a suitable target, it is better to be replaced by the average pieces of plywood of one cubic meter timber. Increase the rate of long timber as much as possible and manufacture the plywood of 915mm×1830mm(3′×6′)as the main size. If the quanlity of log is favourable, manufacturing 1220mm×2440 mm(4′×8′) as the main size and can get tile highest rate of thin plywood. To open the market of thick plywood and to manufacture a proper rate of thick plywood is favourable to raise up the rate of thin plywood. Change in rate of thin plywood affect the economic benefit.
