If the window is the eyes of a dwelling, then the door is the neckline of the dwelling. It is an indispensable real thing and an ornament that cannot be omitted. >>>Links: Construction and acceptance of wooden doors and windows The doors are divided into two major categories - outdoor 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, with wooden, plastic, metal, glass, forests and dazzling. Looking at the world today, there is still a lot of wood, so it is important to understand the choice of wood. Where solid wood doors cannot be completely dried, it is impossible to escape from the law of thermal expansion and contraction, so it is possible that surface deformation will occur. The only difference is that the solid wood door with high solidity has a small deformation coefficient, which is not even visible to the naked eye, while the poor solidity door has a relatively large deformation coefficient. The level of compactness of the solid wood door can also be judged by hand, and the lightness of the door is the most convenient method of judgment. In general, heavy solid wood doors have small deformation coefficients. For example, hardwood doors or hardwood doors are replaced by hardwood doors. The deformation factor 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 the joints are tightly fitted, the dimensions are fine and the installation is fine, there will not be any significant changes later. In short, the choice of solid wood doors is mainly material selection, selection of artificial wood doors is mainly selected work, mastered this method, you can basically solve the hidden dangers of door deformation. Experts remind you to choose the door trick: a look at the finish (shape and paint color); 2 see the proof (toxic material content); 3 look at the material (solid wood material); 4 look at the work (whether the size of the rules, strict fit). Mastering this "four look" will not discriminate between the true and false in the maze of the door. Doors to buy wooden doors brand security doors wooden doors and windows residential glass door prices glass door DH series homogeneous & emulsification pump is composed of a first-class working chamber. The working chamber is equipped with a group of 3-6-layer stators and 3-6-layer rotors. The tooth discs of each stator and rotor are from coarse to fine, so that the original granular materials of different thickness can smoothly enter the working chamber for layer by layer crushing, dispersion, fine, homogenization and emulsification.There are 5 kinds of products in this series. Developed independently by our company, the application technology is very mature. We have a strong technical team and our users all over the world.
