Question 2: The purchased pressing plate is deformed. How to flatten? If there is no deformation, please soak it in water and flatten it with a flat hammer.
Question 3: Ask what to do if the wood is deformed (the board is not processed). If you are not in a hurry to use it, I will give you one of our methods. When I was a child, I saw my dad put things under the sides of the board, put heavy objects on the board, and baked the empty part in the middle with fire. This method is very effective, it takes about 2-3 times.
Question 4: How to prevent the plate from cracking and deformation 1. Keep the water from losing (only temporarily for a log).
Just throw it in the water and soak it.
Throw oil to isolate the air.
Second, keep the balance of water loss.
At present, steam drying is more mainstream.
First build a relatively sealed house with air circulation, and then build several high-power exhaust fans and dryers.
The dryer generates a lot of heat, which forces the wooden boards stacked in the house (wooden boards are not logs and cannot be dried or dried for a long time) to evaporate water quickly, and at the same time, the exhaust fan circulates a lot of water vapor, forming a relatively stable high temperature environment.
It can make the wood board achieve a certain drying effect in a short time (7- 15 days). Of course, the time corresponding to different tree species is different.
This method is suitable for furniture factories and timber merchants.
Question 5: How to avoid wood deformation At present, many families use a lot of wood products in decoration, such as curtain boxes, heating covers, fixed furniture, wooden lines, door and window covers and so on. However, once the indoor temperature and humidity change greatly, some wood products will have problems such as cracking, warping and deformation. In fact, many quality problems in home decoration are caused by the moisture content of wood products.
Wannian Flower City is the first choice for waterscape blues real estate.
Whether it is solid wood or man-made board, all wood products contain certain moisture. Many consumers think that the drier the wood, the better. In fact, this view is biased. Only when the moisture content of wood is stable in the normal range can we ensure that there is no quality problem in the decoration. The moisture content of wood materials used in general households should be around 8%. If the moisture content is too high or too low, it will cause the quality problem of wood work in home decoration.
In order to keep the moisture content of wood stable, you should pay attention to:
1, manual disk is used more. Compared with solid wood materials, the texture properties of various wood-based panels are much more stable. Because all solid wood materials are textured, cracking, warping and deformation will inevitably occur when the temperature and humidity change greatly. Wood-based panel is to decompose wood into chips or wood pulp, and then make it into boards again. Because it breaks the original physical structure of wood, the "deformation" of wood-based panels is much smaller than that of solid wood when the temperature and humidity change greatly.
2. Pay attention to the details in the construction. In home decoration, the key to the quality of wood products lies in the construction, especially the handling of details:
All wooden products should be painted immediately after installation. This layer of paint is called "topcoat", which can not only protect wood products, but also isolate moisture and maintain the normal moisture content of wood; The adhesive must not be mixed with water. At present, in home decoration, white latex is generally used as the adhesive for wood joint. Some workers add water to white latex in order to cut corners. This not only reduces the strength of the adhesive, but also easily leads to quality problems of wood products after water absorption. All the wood will be left for a few days. After you buy the wood for decoration, you'd better leave it at the decoration site for a few days before using it. The purpose of this is to make the moisture content of wood close to the level of new houses.
Be careful when buying materials. When you buy wood for decoration, you can't determine the moisture content of wood only by your eyes and hands. Therefore, some people lament that if only by visual inspection, the moisture content of wood can be described as "the fairy is difficult to distinguish." In fact, there are some tips to help you determine whether the moisture content of wood is qualified. Generally, the dried wood has obvious characteristics, obviously reduced weight, not cold to the touch, brittle knocking sound, "rushing" sound when pushing and planing, and the shavings are hot and smooth. Wood with high moisture content is heavier, feels cold, is not brittle when pushed, and even wipes. This kind of wood is useless.

Question 6: How to correct the warping of plate? I believe this is a very difficult question, thank you in advance! In the construction site, generally, after the plates are leveled, they are pressed with heavy objects such as sandbags to prevent deformation or correction.
Question 7: The plate is severely deformed after heat treatment. How to correct it? In short, there are only five words: kaiping machine reform. In detail, the word 12: kaiping machine just rolls the board twice. []
Question 8: What should I do if the wood does not deform? Hello. Dry shrinkage and wet expansion of wood, as well as warping deformation caused by inconsistent dimensional changes in all directions, are a major defect in wood utilization. In order to improve the stability of wood size and prevent the occurrence of wood deformation, the following methods can generally be adopted: 1. Mechanical pressing through orthogonal lamination is actually processing wood into plywood or laminated wood, and preventing deformation through the action of adhesive. 2. Wood coated internally or externally with waterproof coating can form a complete external surface coating, thus greatly reducing the moisture absorption rate of wood and obtaining quite good moisture-proof effect. It should be pointed out that the dimensional stability of external veneer wood is only temporary. If it is placed in an environment with high relative humidity for a long time, or in an environment with rapid changes in relative humidity, or stored in the open air, its moisture-proof rate will be greatly reduced. However, due to the impregnation of paint, the internal coating has certain dimensional stability. However, from the waterproof and moisture-proof mechanism of finishing treatment, the effect of covering the internal micro-surface of wood is worse than that of covering the external surface. Because the inner surface area is much larger than the outer surface area, it is difficult to form a complete coating on all inner surfaces. Therefore, the dimensional stability of wood processed by internal finishing is not as good as that of wood processed by external finishing. 3. Expanding the cell wall of wood with chemicals The so-called expansion treatment is to fill the cell wall with chemicals to expand the cell wall, but the dried wood does not shrink to its original size, thus esterifying with cellulose, hemicellulose and lignin of wood, replacing hydrophilic hydroxyl with hydrophobic acetyl, reducing free hydroxyl on wood molecules and reducing hygroscopicity, thus improving its volume stability. After acetylation, all kinds of wood not only keep their beautiful natural effects, but also lose their original colors, which can degrease the wood containing resin and help improve the paint finishing performance and stability of wood. The above methods can reduce the occurrence of wood deformation.
