What are the differences between water -based paint and paint? Spray brush and not to enter the pit after watching it

The use of paint in home construction is essential, so it is very important to know the relevant types before construction, so

The difference between water -based paint and paint

What are there? Let’s take a look together!


The meaning of water -based paint and oily paint:

Water -based paint: Only water is used as a diluent, which is harmless to human health. It does not contain harmful carcinogens, non -toxic and tasteless, and you can check in after painting. Because it does not contain harmful substances, it will not volatilize to the air, so there will be no defects such as yellow change, which will last long. The construction method is mainly used during construction.

Oil -based paint: Banana water and daily water are used as diluents, which contains a large amount of harmful carcinogen such as benzene and dyshane. It contains a strong irritating smell, which is unbearable and harmful to the human body. It contains a large number of harmful substances and endangers human health. Generally, from January to February after use, strong irritating odors volatilize to basically tasteless, and harmful substances continue to slowly release long -term volatilization, so it is easy to change and durable.

What is the difference between water -based paint and paint?

1. Different wear -resistant coefficients

If the paint is not well maintained well, the color loss will occur after a long time. But water paint is different. It has a hard surface after brushing, and has a certain degree of flexibility, and it will not fade for a long time, but the wear -resistant coefficient is slightly weaker than the paint.

2. VOC content is different

VOC refers to a compound that can naturally volatilize in the air in the air under normal circumstances. The content of water -based paint VOC is super low, but the VOC released by the paint is several times or dozens of times in the air standard. So we can smell a lot of paint. All in all, the higher the VOC content, the less environmental protection, so try to choose water -based paint when choosing.

Third, the smell is different

Many people know that the paint will have a scent of nose and other odors that are unclear. Many people on the market now put various spices in the paint to pretend to be paint. But the taste of the paint itself is easy to distinguish. The smell of water -based paint is very mild. Some water -based paint cannot smell directly. The taste is a aroma. Xiaoyi Sheng editor reminded everyone to distinguish it carefully when choosing paint, otherwise the taste at home will be difficult to smell.

Fourth, the construction is different

It is very convenient when the water paint brush is brushed. As long as you look at the manual, you can paint it yourself. However, it can only be painted by professionals or specialized training.

What are the spray brushing skills

Tip 1: Use clean water to adjust the paint to the appropriate spray viscosity, measure the -4 viscosity meter, and the appropriate viscosity is generally 20 seconds to 30 seconds. If there is no viscosity meter for a while, you can use the visual monitoring method: stir the paint with a stick (iron rod or wooden stick), and then pick up to the 20 cm high place to stop observing. It is too thick; if the upper edge of the barrel is the broken line, it is too thin. When staying at a height of 20 centimeters, the paint liquid becomes a straight line, and the disconnection becomes down in an instant. This viscosity is more appropriate.

Tips: It is best to control the air pressure at 0.3 ~ 0.4 MPa (3 ~ 4 kg/square centimeters). The pressure is too small, the lacquer liquid is not good, and the surface will form numbness; the pressure is too large and easy to flow, and the paint mist is too large, which is a waste of materials and health.

Tip three: The distance between the nozzle and the surface is generally 300 mm to 400 mm. When you are too close, the paint film is easy to flow; too far paint fog is uneven, prone to numbness, and the nozzle is far from the object of the object, and the paint fog spreads on the way to cause waste. Slow -drying spraying distance can be farther, fast -drying paint spraying distance can be closer; when the viscosity is thick, it can be closer, and the viscosity can be farther away; If it exceeds this range, it is difficult to obtain the ideal paint film.

Tips 4: The spray gun can be moved up and down, left and right at a constant speed, and the nozzle should be sprayed straight at the object surface to minimize the oblique spraying. When the ends of the object are sprayed, the hand of the spray gun trigger should be loosen quickly to reduce the mist mist, because the two ends of the objects often accept more than two or more spraying, which is the most likely to cause flowing.

Tips 5: When spraying, the next one should be pressed 1/3 or 1/4 of the previous way, so that no omissions will occur. When spraying fast -drying paint, it is necessary to spray it in order at a time.

Tips 6: The order of spraying is: difficulty first, then easy, first and then outside. First, the high place is low, then a small area, then a large area, so that the paint fog that will not spray after spraying the painted paint film is sprayed on the sprayed paint film, destroying the sprayed paint film.

The above is shared this time for everyone
