Problems solved by technology

Second, the management level is poor and the product qualification rate is low
Third, the product application field is narrow and the application technology is backward
3. Mutagenic effect: high concentration formaldehyde is also a genotoxic substance
The formaldehyde emission potential of the core layer of the board is relatively high, the reason is that the temperature of the core layer is low, the moisture content is high, the pH value is also low, the degree of curing is poor, and it is easy to hydrolyze to produce formaldehyde; with the decrease of the moisture content of raw materials after sizing, The amount of formaldehyde released during production and products decreases, and other performances of the product are reduced, which is not conducive to heat transfer, but will increase the amount of formaldehyde released in the product

Abstract

An environmental protection type composite board is composed of a joist layer and 1-2 layers of tea leaves and tea stems. Its preparing process includes such steps as choosing tea leaves and tea stems, fermenting, preparing joist, mixing tea leaves and tea stems with resin, and hot pressing.

Description

technical field [0001] The invention relates to an artificial board, in particular to an environment-friendly tea composite board used for indoor and outdoor decoration, furniture, etc. The invention also relates to a processing method for the composite board. Background technique [0002] According to incomplete statistics, more than 3,000 wood-based panel factories have been built in the country today, and the total output in 2000 reached 20.0166 million cubic meters, an increase of 4.9866 million cubic meters compared with 15.03 million cubic meters in 1999, with a growth rate of about 25%. . A wood-based panel industry structure dominated by plywood, particle board and medium-density board has been formed, and the trend of growth continues. Among the more than 3,000 wood-based panel enterprises in the country, there are more than 2,000 plywood enterprises, but only more than 100 of which have an annual production capacity of more than 10,000 cubic meters, most of which ...
