Because the paint has a variety of colors and luster, such as matt, matt, semi-gloss, you can easily choose to fully reflect the personalized decoration style. For example, silk latex paint, which is more popular in recent years, has a silky matt finish, smooth and delicate feel such as silk, which can create a warm and romantic atmosphere for the living room.
There are several criteria for choosing latex paint:
First, it is washable. Because the wall is easily soiled, families with children will be more troubled by graffiti. After the latex paint containing the waterproof formula dries out, it will naturally form a dense waterproof paint surface. With clean water or mild detergents, you can easily wipe off stains without removing the paint itself. The latex paint sold in the market will have this function as long as it is a regular manufacturer's production and meets the requirements of the national standard for waterproof latex paint. Some manufacturers have proposed that the number of washing times exceeds the national standard several times. In fact, this does not make much sense for the average family. The provisions of the national standards have fully satisfied the requirements of home decoration.
Second, it is the moisture-proof and mildew-proof function of latex paint. Has the wall of your home been too wet to cause mildew? This is especially prominent in basements, bathrooms, or in wet weather. Anti-mold and moisture-proof latex paint can effectively block the invasion of water on walls and walls, prevent moisture penetration, and prevent mold growth.
Lasting paint is not easy to fade, fall off is another point consumers should pay attention to in the selection of latex paint, in general, latex paint to maintain a new bright 3-5 years is more in line with family requirements.
In addition, everyone is most concerned about whether latex paint is truly non-toxic, safe and environmentally friendly. Here you can tell that the main components of latex paint are non-toxic resin and water, and lead and mercury are not included. No irritating odor will be produced during the brushing process and will not cause harm to the human body, living organisms and the surrounding environment. However, you must purchase latex paint products marked with the manufacturer, production date, and shelf life, as well as the lead-free and mercury-free labels.
After opening the lid, the truly environmentally-friendly emulsion paint should be water-based, non-toxic and odorless, so if the user smells pungent or industrial flavor, it is not ideal. After a period of time, the surface of genuine latex paint will form a very thick and elastic oxide film, which will not be easily cracked, while inferior products will only form a very thin film that is fragile and has a spicy smell. Mix the latex paint with a wooden stick and pick it up with a wooden stick. The high-quality latex paint will become fan-shaped when it goes down. Touch with your finger, genuine latex paint should feel smooth and delicate. The latex paint is applied to the wall and wiped with a damp cloth. The genuine color is bright as new, and the defective product will fade due to poor coagulation and water resistance.

Plate rolling is a process of continuous three-point bending of sheet metal using a plate rolling machine. The equipment puts the sheet material between the upper and lower work rolls when rolling. The upper roller is raised and lowered vertically, and the two lower rollers rotate and move horizontally relative to the axis of the upper roller. When the upper roll descends, the plate is plastically deformed and bent between the upper and lower work rolls. The continuous rotation of the bottom roller drives the steel plate to advance and retreat through the friction between the plate and the roller to complete the coiling.
1. Pre-bending. When the plate is rolled, there is a length at both ends of the plate that does not bend because it does not touch the upper roller. It is called the remaining straight edge. In the process, the minimum force arm at which the plate starts to bend is called the theoretical remaining straight edge. The bending form (symmetrical bending, asymmetrical bending) is related.
2. Centering. The purpose of centering is to make the generatrix of the workpiece parallel to the roller axis to prevent skew.
3. Roll round. Rolling is the main process of product forming, which is divided into two types: one-time feed and multiple feeds. Multiple feeds are commonly used for rolling thick plates. The number of feeds depends on the technological constraints (such as the maximum allowable deformation during cold rolling) and equipment constraints (such as non-slip conditions and power conditions). When the rebound of the cold coil is significant, a certain amount of overcoiling must be added.
4. Straightening round. The purpose of rounding is to make the curvature of the entire circle as uniform as possible to ensure product quality. The general rounding process is divided into three steps:
(1) Load: According to experience or calculation, adjust the work roll to the position of the required maximum correction curvature.
(2) Rounding: Roll the roller 1 to 2 turns under the corrected curvature to make the entire curling rate uniform.
(3) Unloading: gradually unload the load, so that the workpiece is rolled several times under the gradually reduced correction load.
