benign development As we have learned, our country has man-made board to produce a business many 6000, the company that has certain scale of production among them has wood deck lumber composite more than 400 only, and crop takes the throughout the country 1/3 of man-made board total output, but 7% what accord with demand of environmental protection product. See not hard from this, the product that great majority

enterprise produces fails to achieve popular composite wood prices requirement of formaldehyde content standard. The personage inside course of study points out, our country man-made board be about to improve product quality, make its reach market admittance or level of green environmental protection, except should replacing facility, strengthen management, raise a worker to produce the respect such as cheap tongue and groove wood skill to make

great efforts besides, still should make full use of resource of man-made board production is natural sanitarian character. For example many tree contain special type grease, most durable lasting solid stain for decks special fragrance and phenol kind material, they are right purify air, insect-resistant drive is formic wait for a respect to have surprise effect. In the meantime, scientists and Technologists should
