Embodiment 1

[0035] A method for drying larch wood in Saihanba area, comprising the steps of:

[0036] a. Cut the larch wood harvested on Saihanba in autumn into 30cm wide and 23mm thick plates, and place them in the room to dry naturally for 35 days. Dry the room with no direct sunlight, normal ventilation, and a relative humidity of 35 %.

[0037]b. Put the naturally-dried wood into the drying kiln, and press the standard drying layer of 500 kg / surface square meter per standard board stack. Among them, the standard board stack is: the forming size of the board stack is L4000mm×W1800mm×H2500mm; The standard drying layer is: the appearance size of the drying layer is L1800mm×W100mm×H100mm, the concrete is not lower than C30 made of ordinary Portland cement above PO42.5, and the rebar of ф8mm is added (4 rebars for each drying layer ) production.

[0038] One-time drying treatment: After the drying kiln is turned on, the dry bulb temperature in the kiln is raised at a heating rate of 3°C / ...

Abstract

The invention relates to the technical field of wood drying and particularly discloses a method for drying larchwood in a Saihanba area. The method comprises the following steps that a, the wood is placed in the indoor space to be aired naturally; b, the naturally-aired wood is put into a drying kiln to be subjected to first-time drying treatment; c, second-time drying treatment is conducted; d, third-time drying treatment is conducted; and e, final drying treatment is conducted. According to the method for drying the larchwood, the phenomena that the larchwood in the Saihanba area has the characteristics of numerous oil sacs, numerous knots, nightsides, sunny sides and the like, and consequentially, products manufactured by the larchwood are prone to being subjected to oil sac seeping, surface spot-type discoloring and paint-removing can be avoided, the oil sacs can be removed thoroughly after the larchwood in the Saihanba area is dried, the deep-processed wood is smooth in surface and long in service life, and the added value of the larchwood in the Saihanba area is greatly increased.

Description

technical field [0001] The invention relates to the technical field of wood drying, in particular to a method for drying larch wood in the Saihanba area. Background technique [0002] Saihanba is located in Weichang County, Chengde City, Hebei Province. It belongs to the mountainous area of ​​northern Hebei. This area is not only the intersection zone of temperate zone and warm temperate zone, but also the transition zone between plateau grassland and mountain forest vegetation. It has rich forestry resources and the forest area reaches 734 10,000 mu, accounting for 23% of the province's total, the forest coverage rate reached 53.1%, and the forest stock volume was 24.95 million cubic meters. It has become the largest county in Hebei Province in terms of forest resources. Among them, the local larch in Saihanba (based on the original seeds of larch in Northeast China, a local tree species suitable for Saihanba area cultivated through several generations) is the main tree spe...
