Wall decoration is a more important part of house decoration, not only beautiful, but also practical. If you want to decorate the wall, you can't neglect the preparation work before painting. Although the preparation is quite time-consuming, but you can get really satisfactory results, why not do it? Actually, it is spent on the wall. The time in front of the preparation work is more important than the time spent on paint painting. The following nine positive building materials network introduces you to the seven preparations in front of the painting wall.
1. Dry in the first step. The materials used in building walls are usually “water wet†materials because they are all blended with water and have a very high water content. Excessive moisture can affect the adhesion of most coatings, causing blistering, cracking, and growth of bacteria. Therefore, it is very important to make the wall dry before painting. If the wall is not completely dry, use a waterproof primer for preparation before painting.
2, the second step to the salt flower "water wet". Building materials usually contain salts and alkalis. During the drying of the structure, the salt in the material will ooze out along with the moisture and accumulate on the surface. At this time, wipe it with a wet cloth or a hard brush to remove it. The work should be repeated for a few days, until the wall no longer appears salt flowers within 48 hours. If the time is tight, the salt and alkali can not be removed, and the alkali-resistant primer can be used as the base layer to ensure that the surface coating is long-lasting.
3. The third step is to clean the base. Remove the splashed cement particles and any loose or broken deposits. If there is dust or damage, remove the dust and repair the damaged parts. For varnished old walls, if they are blistering, cracking or peeling, they should be completely scraped off.
4. The fourth step is to approve the wall. In order to obtain the best brushing effect, after cleaning the base layer, the entire wall is scraped with the inner wall powder, and then dried. If you are serious, you can repeat this process two or three times until the wall is flat and smooth.
5, the fifth step on the primer. A layer of waterproof primer or alkali-resistant primer can be applied to the smooth wall after scraping to enhance the durability of the coating.
6, the sixth step to make special effects. Sometimes in order to create some artistic effect on the wall, such as video wall, using special construction tools, different layers of construction techniques are used to roll a thick layer of thick intermediate material on the wall to create a decorative texture with different styles. Such as orange peel, sand wall pattern, embossed lines and so on. (If you don't need special effects, this step can be saved)
7, the seventh step on the surface coating. After the above series of basic work, finally the last step, then you can choose the color you like to decorate your new home.
An electric Gate Valve is a type of valve that uses an Electric Actuator to open and close the gate of the valve. The gate is a flat or wedge-shaped piece that moves perpendicular to the flow of the fluid. When the valve is open, the gate is lifted or pushed aside to allow the fluid to pass through. When the valve is closed, the gate is lowered or pressed against the valve seat to prevent the fluid from flowing.
Electric gate valves are commonly used in industrial applications where precise control of the fluid flow is required. They are often used in pipelines, water treatment plants, oil and gas refineries, and chemical processing plants. The electric actuator allows for remote control of the valve, which can be operated from a control room or a computerized system. This makes it easier to monitor and adjust the flow of the fluid, which can improve efficiency and reduce the risk of leaks or spills.
