Wood modification treatment technology for flooring, furniture and fireproof wood production

According to the actual situation and suggestions of the timber production enterprises, Beijing Jinsheng Engineering Materials Research Institute has carried out several improvements on the original wood modification treatment technology. The improved scheme not only reduces the cost, but also shortens the production time and deepens the treatment. depth. Now this technology is being promoted to various timber companies, hoping to get everyone's attention, and hope to have effective cooperation. The types of wood treated by this technology mainly include pines of conifers, such as wood of white pine, larch, and wood of broadleaf poplar, paulownia, etc. This technique can make the following changes in the wood when processing this kind of wood:

Degreasing, mainly refers to high-fat pine, the high fat content of pine and the exposed oil sac on the surface make the use of pine very limited, especially larch, a large number of oil sacs make the use of this wood It is very difficult. At present, there is no effective solution at home and abroad. Most of them use the method of digging the wood of the oil sac part and then filling up a small wooden block in the place where it is dug, which is usually called “digging and repairing”. Labor costs, wood defects are obvious, and when the modification process is used, the rosin in the surface oil sac will be completely dissolved, leaving only a small gap, and repairing is very easy.

Hardening, the process of degreasing and modifying wood will not only damage the physical properties of the wood, but also significantly increase the surface hardness of the wood. This is a place where the process is significantly different from other similar technologies. The traditional notion of damage to wood has been completely changed in the process.

Flame retardant, the wood treated by the process has obvious flame retardant properties, and can effectively inhibit yang burning and smoldering when exposed to flame. Due to the rationality of the treatment formula, the smoke generated when contacting the flame is non-toxic. Most of the fire retardant plates usually contain an amine flame retardant, which produces highly toxic gases at high temperatures.

Moisture proof and mold proof, because the wood treated by this technology will form a hardened outer layer around, the fibers in the layer are wrapped by the admixture, and the forces are evenly applied, which can effectively prevent the mold caused by moisture. The deformation can also be prevented, which is very useful for larger gauge sheets.

This wood treatment technology is mainly used in the following three areas:

Solid wood flooring, using this technology to treat larch and white pine, its products can be used for solid wood flooring, (white pine needs pressure and densification) to enable manufacturers to obtain a low cost and good performance product, the price can be equal to the laminate floor. Very suitable for the level of consumption in our country.

Solid wood furniture, treated wood can be used for the production of solid wood furniture. Because of the large size of the raw materials of this kind of wood, it is not easy to be deformed after treatment. Therefore, the use of finger joint boards can be avoided, and the material cost is only two points of hard wood. One to one third or so.

Fireproof wood, this technology can be used to produce fireproof wood and fireproof panels for decoration and decoration. The treated wood has better fire resistance. When the treated wood is used for fireproof wood keel and fireproof decorative panels, it can no longer be used. The use of fire-retardant coatings can significantly reduce the material and labor costs of construction. These products are currently not supplied with molded products due to technical problems, so the market prospects are very promising.

The wood modification treatment technology has been improved and optimized several times to make the implementation process relatively simple, the cost of processing the wood is low, no major equipment investment, the site occupation is small, the site environment requirements are not high, and the ambient temperature can be carried out above zero. The southern region can be carried out outdoors all year round. The annual processing capacity is about 200 square meters per 1000 square meters. The cost of processing plates is 4 yuan per square meter, the processing time is 15 days, and the treatment depth is 6 mm. In the calculation, after the cost per square meter of material plus the direct processing cost, the price of the modified floor blank obtained is about 40 yuan per square meter.

The wood treated with this technology is very beautiful in color and texture, and can be painted with natural colors, especially the best color method of larch in the process, which can produce a very beautiful purple-red and clear texture. Wood, after discussion with the multi-wood companies, received consistent praise.

The wood treated by this technology not only has good performance and low cost, but also has good environmental protection performance due to the rationality of the process design, no harmful gas release, and will not pollute the indoor environment.

The technology also has rich follow-up deep processing technology, which can not only be used for post-processing such as compression, hot bending and hot press forming, but also can be applied to the production of fireproof blockboard, fireproof plywood, etc., and its application prospect is very broad.

The growing supply of wood is an indisputable fact. The effective use of large-volume, low-priced timber resources and the efficient use of artificial fast-growing forests are not only in line with China’s relevant policies, but also for production companies. Very obvious practical significance and long-term strategic significance.

This technology is a key scientific research project in Chongwen District of Beijing in 2000. It has stable technology and good process repeatability. Our institute bears full responsibility for the authenticity and intellectual property rights of this technology.

In order to enable this technology to be put into practical application as soon as possible, we are now seeking cooperation with various wood and wood products processing enterprises. We will certainly make you willing to implement this technology under very favorable conditions. Beijing can adopt technology transfer or technology shareholding. The method of foreign companies adopts the form of low-price technology transfer. We hope that all enterprises are interested in this technology and contact us.

If you think you need it, we can provide further text and imagery. Image data will always be sent by email.

Shoe Leather is made of raw materials for shoes, in the production of shoes on the surface of the upper leather a lot of raw materials, leather upper leather, PU upper leather, PVC upper leather and so on.Mainly have a positive leather, modified leather, suede and other varieties. Multi-use pigskin, leather, sheepskin as raw materials, chrome tanning production, the general dyed a variety of colors and the emulsion refueling. In addition to suede and individual non-coated leather, mostly painted. Its thickness according to the requirements of different raw materials and footwear changes (between 0.5 ~ 1.8mm), without lining the thick upper leather up to 2.5mm or more.
