A look at the finish (styling and paint color); second look at the proof (toxic material content); three look at the material (solid wood material); four look at the work (whether the size of the rules, strict integration). Only by mastering this “four look†will it not be in the maze of the door without distinguishing authenticity from falsehood.
If the windows are the eyes of a dwelling, then the door is the neckline of the dwelling. It is both an indispensable real thing and a decorative door that cannot be omitted. It is divided into two major categories - outdoor doors and indoor doors.
Today's outdoor doors have become the world of security doors. Anti-theft is the main function and will not be repeated for now. Indoor doors are full of tricks, wooden, plastic, metal, glass, forests are always dazzling.
Looking at the world of today's gates, it is still mostly wooden, so we should focus on the choice of wooden doors. Wooden doors are divided into two categories: solid wood doors and artificial wood doors. The brands of these doors are numerous and varied. Although the prices vary, the sellers claim to be good and the buyers are ashamed. It is as if they are entering the maze and not distinguishing things. Nowadays, everyone has a handful of money in their hands, and the decoration of their homes is perfect. Naturally, the aesthetic needs of the door are also increased. However, the use of wooden doors is always difficult to avoid a common problem, that is, deformation, commonly known as "warp." How to solve this problem? Where solid wood doors can not be completely dry, it is impossible to escape the law of thermal expansion and contraction, so they are likely to change the form, the difference is that solid wood doors with high compaction coefficient of deformation is small, even the naked eye Not to come out, but the poor compactness of the door deformation coefficient is relatively large.
The level of compactness of the solid wood door can also be judged by the hand, and the feeling of the door is a most visual judgment method. In general, heavy solid wood doors have small deformation coefficients, such as hardwood doors or hardwood doors with higher grades. The deformation coefficient is very small. Of course, such solid wood doors are also expensive. Artificial wood doors are made of wood fiberboard. Relatively speaking, the deformation coefficient is very small. As long as Chinese wooden door experts are installed, they are tightly fit together, and they are well-sized and installed. They will not change significantly afterwards. In short, the choice of solid wood doors is mainly selected materials, the selection of artificial wood doors is mainly selected work, mastered this method, you can basically solve the hidden dangers of door deformation.
Wooden door expert interpretation: Buy wooden doors to pay attention to the installation quality of the door cover
Wooden doors are durable goods and are very decorative and practical products. Therefore, long-term considerations should be taken in terms of brand, material selection, process, and quality assurance. If a door is not durable, it will directly affect the practical effect and service life of the wooden door. The door cover is commonly known as the door frame. It refers to the decorative design around the door. It bears the weight of the entire wooden door and can echo the overall decoration style. According to statistics, complaints about wooden doors are mainly on door covers. Sometimes a door is often a door leaf or it is intact, but the joint between door leaf and door cover has loosened, because with the increase of the number of wooden door opening, the screws are It will slowly loosen, the door gradually sinks, causing the switch to be sluggish, and it will cause unnecessary trouble for your decoration. Therefore, first the door must be nailed, it has a strong nail holding force, so that the door is not easy to fall off: Second, the water resistance of the door is very critical, especially the bathroom door, once the door cover damp, its surface will be made Black, swells, peels, cracks, and sometimes causes frying. The door cover is directly in contact with the ground. If the material is not properly selected, the door leaf will sink and drag the floor, causing the switch to be lax and scraping the ground. Once a problem occurs in the door cover, it may damage the floor or wall of your home during the repair, causing unnecessary losses. Therefore, when consumers choose wooden doors, do not forget to pay attention to the door.

Low porosity clay bricks are made of low aluminum mullite as the main raw material, formed by high pressure molding and high temperature sintering. The main mineral composition is mullite phase, the product has excellent high temperature physical properties and chemical erosion resistance.
Low porosity clay brick stability is good, the degree of erosion does not occur sudden change, than ordinary clay brick life increased by 2 to 3 times. Thermal conductivity, specific heat and solubility, respectively, than ordinary clay bricks 2 times higher than 10% and 40%, heat storage capacity than ordinary clay bricks 50% to 60% higher than the thermal efficiency of the kiln can be improved.
Low porosity clay bricks are characterized by:
1. Low porosity, 13 to 15%;
2. Load softening temperature is high for about 1472 ℃;
3. High compressive strength at room temperature, generally about 100MPa;
4. Good volume stability at high temperature and good abrasion resistance;
5. good resistance to infiltration and erosion.
Low porosity clay brick as a good clay refractory brick products, so often used in chemical erosion, temperature fluctuations in the environment, such as steel, glass, chemical industry. The effect is quite obvious in the use of glass hot room and the use of iron water tank.
