In recent years, with the development of the domestic construction industry, especially the real estate industry, the improvement of people's living standards, the interior decoration industry is heating up, the wood flooring industry is developing rapidly, the output is getting bigger and bigger, and the floor is economical and beautiful. Wear-resistant, stable, etc. are the main conditions for the selection of wood flooring, so that the plate species are more and more.
1 Domestic wooden floor production status
1. 1 Type of wooden floor
1 solid wood flooring: mainly solid wood slats parquet floor, solid wood slats (flat mouth, tongue) floor, solid wood glue, standing wood floor and so on. 2 solid wood composite flooring: two, three, five, six-layer solid wood composite flooring. 3 Glulam flooring: Plywood, particleboard, medium (high) density fiberboard as the substrate, the surface of the veneer is laminated. The particle board is made of chipboard and medium (high) density fiberboard (core material), the bottom layer is ordinary melamine balance paper, the surface layer is divided into two layers, the lower layer is melamine impregnated paper or marble grain of wood grain decorative paper, and the upper layer is white alumina. Alloy fine sand melamine paper. The finished product is generally (1 2 0 0 ~ 2 2 0 0 ) × (1 80 ~ 2 2 0 ) × (6 ~ 1 2 ) mm. This kind of floor is also called laminate flooring. 4 Bamboo-wood composite flooring: the surface layer is bamboo and the bottom layer is wood composite floor.
1.2 Production capacity and output
Wood flooring companies are small and scattered, and they are developing rapidly, and industry management has not adapted to their development. On January 28, 1998, the China Forestry Industry Association Floor Committee was established. Due to various reasons, it is still difficult to calculate accurate figures. According to the statistics of the second national industrial census in 1995, the wooden floor of China in 1995. There are 2,380 manufacturers (country to village level), with a production capacity of 170 million m2, more than 70 bamboo flooring manufacturers, and a production capacity of 5.8 million m2. The actual production volume and sales volume are difficult to count. According to the statistics of the second national industrial census in 1995, there are 140 wooden flooring enterprises in Jiangxi Province with a production capacity of 7.4 million m2. There are 16 bamboo flooring manufacturers with a production capacity of 300,000 m2. The largest of these is Fulin Wood Industry Co., Ltd., which introduces a high-grade parquet flooring production line with an annual output of 400,000 m2. The actual production volume and sales volume of the province is difficult to calculate.
Before 995, most of the wood flooring in China was solid wood flooring. From 1 988 to 1 998, China introduced nearly 40 production lines of laminate flooring with a production capacity of 400,000 m2, but the annual sales volume was only 150-200,000 m2, second only to solid wood flooring. . In addition, more than 20 three-layer glued composite board production lines were introduced, each with a production capacity of 25 to 550,000 m2.
How large is the sales volume of wood flooring in China? In the third national industrial census in 1995, the number and capacity of these small enterprises were highly mobile due to the statistics of small enterprises to the village level, especially after 3 years. The test of multiple markets, the actual number of enterprises, production capacity and sales volume are difficult to count. In 1998, the sales volume of wood flooring in China was estimated to be 100 million m2, and some said it was 150 million m2. Some experts estimated that the sales volume was 600,000 m2. It is good to reach 100 million m2 in 1999.
The author combines the following three factors: 1 In 995, the number and production capacity of wood flooring enterprises reached 170 million m2. If the productivity is estimated at 70%, the annual production is 120 million m2; the introduction of 2 1 988 to 998 And the actual production increased by the production of the laminate flooring production line and the composite floor production line; 3 China's new urban residential buildings in 1992-2000, 122 million m2, with an annual output of 240 million m2. If more than 50% are decorated with wooden floors, it is also required to have 1.2 million m2 of wooden floor. It is estimated that the sales volume of wood flooring in China in 1998 was between 120 million m2 and 150 million m2.
1.3 Product grade and quality
Due to the limitation of raw materials, the solid wood flooring in our country is not many varieties, and the grades of the wood are not too high, resulting in low grades. The commonly used materials are limited to Cyclobalanopsis glauca, eucalyptus, cherry, maple and beech. , jujube wood, birch, eucalyptus, eucalyptus, ash, etc., some enterprises use high-grade imported wood, such as rosewood, etc., to improve the product quality. In terms of processing, most enterprises adopt domestically produced equipment, which is limited by the quality of processing equipment and production management. The quality of solid wood flooring is not high, and it is not up to standard. Some are shoddy, and some are used to reduce production costs. The standard sheet is processed and deformed or mildewed by the user. In the laying of wooden floors, the quality of wooden flooring is not a key part of the quality of wood flooring manufacturing, just as the assembly of mechanical equipment is the key to the quality of component manufacturing. There is no uniform construction code and standard, the technical level of the construction team and personnel is low; the season is not considered during the construction, and there is no gap left at the wall, causing the deformation or bulging of the wooden floor to be too large; If the ground color is not dry, it will cause mildew on the paint immediately or the concrete will not be dry due to the fixed floor. The laying of the wood floor will cause the user to think that it is the quality problem of the wooden floor.
If both manufacturing and laying are carried out in accordance with relevant standards and specifications, the quality of wood flooring in China will be greatly improved.
