The cracking of white paint has always been a major problem in the decoration industry. I have come to the following conclusions and come to the following points. I share it here with everyone.
>>>Recommendations: Brushing Home Choose Decorative Paint Tips
In fact, the white paint process is very simple.
First, first, when carpentry is the foundation
1, white latex should be used well
2, to the wall of the wood to brush bitumen, play a role in moisture-proof
3, composite board does not play hide
4, solid wood edge must be on both sides with white latex, its technology and varnish is not the same, varnish can be without
5, the use of wood to be dry, and some people will sometimes say the white paint does not crack, sometimes cracking, that is sometimes dry wood, sometimes not dry, it is best not to paint white wood directly, especially Small wood density can not be directly painted white paint
6, a certain degree of connection between wood and wood is firm, and painters should check the key points after entering the market.
Second, the painter before the end of the batch is best to use varnish (clear varnish with the same nature as the white paint, do not use the wrong reaction) sealed again and again, when the back cover corners get a bit, the advantage of doing so is to make the outside The moisture does not reach inside the wood, and the water inside cannot come out.
Third, the paint batch of ash is best to use varnish (clear varnish with the same nature as the white paint, do not use the wrong reaction) to adjust the putty, bad construction, a lot of painters like to use flying powder white emulsion adjustable putty, so good construction, But it is not strong against wood, it is easy to peel off, the putty is not thick, can not be approved without approval, the formation of a flat on the line, the less the better (I used to use the atomic stitches, but the suburbs If it is not good, the main atom and the paint can not be well combined, the paint is thin and not visible, and the thicker one is revealed.
Fourth, the white paint used to use a little less titanium dioxide, the best brush is sprayed, and some workers like the primer brush, top paint spraying, that will save the paint, in fact, instead of paint, white paint can not be sprayed More than four times, the more the chance of cracking, the more the person who knows how to do the paint knows, I don't explain too much here, as long as you do the following four points in the construction of the project, the white paint cracks. The problem can be solved. Do not underestimate these points. There are not really many who can do well.

Solenoid valves are electromechanical devices that are used to control the flow of fluids or gases in a variety of applications. They are classified based on their function, construction, and application.
Based on Function:
1. Normally Closed (NC) Solenoid Valve: In this type of valve, the valve is closed when there is no power supply to the solenoid coil. The valve opens when the coil is energized.
2. Normally Open (NO) Solenoid Valve: In this type of valve, the valve is open when there is no power supply to the solenoid coil. The valve closes when the coil is energized.
3. Direct Acting Solenoid Valve: In this type of valve, the solenoid coil directly controls the valve stem, which opens or closes the valve.
4. Pilot Operated Solenoid Valve: In this type of valve, the solenoid coil controls a pilot valve, which in turn controls the main valve.
Based on Construction:
1. Brass Solenoid Valve: These valves are made of brass and are used in applications where the fluid or gas is not corrosive.
2. Stainless Steel Solenoid Valve: These valves are made of stainless steel and are used in applications where the fluid or gas is corrosive.
3. Plastic Solenoid Valve: These valves are made of plastic and are used in applications where the fluid or gas is not corrosive and the valve is not subjected to high pressure.
Based on Application:
1. Solenoid Water Valve: These valves are used in applications where water is the fluid being controlled.
2. Solenoid Air Valve: These valves are used in applications where gas is the fluid being controlled.
3. Steam Solenoid Valve: These valves are used in applications where steam is the fluid being controlled.
4. Fuel Solenoid Valve: These valves are used in applications where fuel is the fluid being controlled.
