Problems solved by technology

Poplar is a fast-growing wood, soft and easy to deform. Therefore, it cannot be directly used for furniture production since ancient times, let alone for solid wood flooring. However, under the current situation of shortage of wood resources in the world, the contradiction of insufficient supply of high-quality wood is exacerbated.

Embodiment 1

[0021] A kind of processing method of surface carbonized poplar solid wood floor provided by the invention comprises the following steps:

[0022] S1. Surface densification treatment: Saw poplar wood into poplar boards with a thickness of 20mm, put them in a drying kiln and dry them to a moisture content of 10%, and then put them into a hot press for compression and densification treatment. The surface of the poplar board is sprayed and softened for 5 minutes, and kept for 15 minutes under hot pressing pressure of 1.1MPa and temperature of 180°C;

[0023] S2, cutting the poplar plank into floor blanks, the size of which is 920×127×16mm;

[0024] S3. Carbonization treatment of floor blank material: put the floor blank into a high-temperature carbonization tank, use steam or nitrogen as a protective gas, and carry out carbonization treatment. The carbonization temperature is 220°C and the time is 15 minutes; the carbonization treatment in step S3 is carried out in four stages. ...

Embodiment 2

[0027] S1. Surface densification treatment: Saw poplar wood into poplar boards with a thickness of 25mm, put them in a drying kiln and dry them to a moisture content of 12%, and then put them into a hot press for compression and densification treatment. The surface of the poplar board is sprayed and softened for 3 minutes, and kept for 20 minutes under hot pressing pressure of 1MPa and temperature of 160°C;

[0028] S2, cutting the poplar board into floor blanks, the size of which is 920×127×18mm;

[0029] S3. Carbonization treatment of floor blank material: put the floor blank into a high-temperature carbonization tank, use steam or nitrogen as a protective gas, and carry out carbonization treatment. The carbonization temperature is 280 ° C, and the time is 20 minutes; the carbonization treatment in step S3 is carried out in four stages. In the preheating stage, the carbonization furnace is first heated to 150°C for preheating. The second stage is the rapid heating stage: qui...

Abstract

The invention discloses a processing method of a surface-carbonized poplar solid wood floor, and belongs to the technical field of floor processing. The method comprises the following steps of S1, placing a poplar board into a drying kiln for drying until the moisture content of the poplar board is 8-12%, carrying out steam-injection softening treatment on the surface of the poplar board for 3-5 minutes, and keeping the poplar board for 10-20 minutes under the condition that the hot-pressing pressure is 1.0-1.2 MPa and the temperature is 160-190 DEG C; S2, machining the poplar board into a floor blank; S3, putting the floor blank into a high-temperature carbonization tank, carrying out carbonization treatment by using steam or nitrogen as protective gas, wherein the carbonization temperature is 220-300 DEG C, and the carbonization time is 5-20 minutes; and S4, brushing and painting the carbonized floor blank to obtain a finished floor. The processing method is used for modifying the fast-growing poplar, the surface strength and the dimensional stability of the poplar are improved, the moisture-proof effect is good, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of floor processing, in particular to a processing method for a surface carbonized poplar solid wood floor. Background technique [0002] With the continuous reduction of the world's timber resources, the supply of high-quality timber raw materials for the timber processing industry is seriously in short supply, and the contradiction between the ever-decreasing timber resources and the growing demand for timber has become more prominent, which has seriously hindered the development of the timber processing industry. Finding and expanding the source of raw materials become the biggest issue at present. On the other hand, poplar has a wide distribution range, many varieties, strong adaptability, and a short growth cycle. Generally, it can become useful in about 10 years. Making full use of poplar, a fast-growing artificial forest resource, can fill the huge gap in timber resources. In today's shortage of timb...
