Problems solved by technology

This method enters the wood capillary system by adding a modifier, but after the modifier blocks the capillary system and the pit system of the wood, the channel for water discharge is blocked at the same time when the treated wood is dry, so that the dryness of the treated wood is reduced. It is more difficult, the drying cycle increases, and the drying quality is difficult to guarantee

Embodiment Construction

[0016] Specific embodiments of the present invention will be described in detail below.

[0017] In an embodiment of the present invention, a hot-press drying method of cedar wood is provided, the specific steps of which are: adjusting the moisture content of cedar wood, closing and heating the hot plate, opening hot-press drying and post-treatment and the like. First, cut the cedar log into 30-50mm thick whole-side boards, and then adjust the moisture content of the cedar wood. First, saw two initial moisture content test pieces at both ends of the wood, and calculate the initial moisture content of the wood after drying. . Then calculate the absolute dry mass of the initial corresponding wood according to the initial moisture content, and then place the wood in a ventilated place to stack and air-dry. Weigh the wood at regular intervals until the moisture content of the wood reaches 25-30%. Then put the wood into a hot press for hot pressing drying, set the temperature of ...

Abstract

The invention relates to the field of wood processing, in particular to a hot-pressing drying method of cryptomeria fortunei wood. The hot-pressing drying method comprises the specific steps that thewater content of the cryptomeria fortunei wood is adjusted, and the processes of hot plate closed heating, hot plate opening, aftertreatment and the like are carried out. According to the hot-pressingdrying method, the wood can be dried to the required water content within short time, meanwhile, the cryptomeria fortunei wood can be compressed to a certain degree, the mechanical property of the cryptomeria fortunei wood is effectively improved, a processing technology is simple and feasible, the processing period is short, and operation is convenient; drying and enhancing of the cryptomeria fortunei wood are achieved at the same time, the problems of the low mechanical strength, drying and the like about the cryptomeria fortunei wood are solved, and the application of the cryptomeria fortunei wood is widened; and the cryptomeria fortunei wood can be used for the fields of furniture manufacturing, interior decoration and the like.

Description

technical field [0001] The invention relates to a wood drying method, in particular to a hot-press drying method of cedar wood. Background technique [0002] Cedar is the main plantation tree species in my country, with a short growth period and large stock volume. Wood drying is a necessary link in wood product processing. In order to prevent wood mildew, discoloration and decay, while ensuring the mechanical strength of wood, the wood needs to be dried to a moisture content of 8-15%. At present, conventional drying methods are usually used for wood, and conventional drying wood is prone to warping, cracking and other defects during the drying process. At the same time, due to the low mechanical strength of cedar wood, it is usually modified to improve its mechanical strength, and then dried to the required moisture content before it can be used. Some documents have published a processing method to improve the performance of cedar wood. In order to improve the performance...
