Artificial solid fabrics include the following weight percentages: unsaturated polyester resin: 5-45wt%; curing agent: 1-6wt%; curing accelerator: 0.01-2wt%; modifier: 0.01-10wt%; filler: 60-83wt%; in which the unsaturated polyester resin requires 20-40wt% neopentanediol and 10-35wt% maleic anhydride.

Artificial solid fabrics are made up of special unsaturated polyester resins, which are different from artificial marble and quartzite, and fillers mixed with soft and hard powders. The finished products synthesize the advantages of the two, make up for the shortcomings of the two and have broad market prospects. So there are more and more solid surface machine manufacturers.

Surface treatment is a process by which a surface layer with different mechanical, physical and chemical properties is artificially formed on the surface of the substrate material. The purpose of surface treatment is to meet the requirements of corrosion resistance, abrasion resistance, decoration or other special functions of products.

For metal castings, the most commonly used surface treatment methods are mechanical grinding, chemical treatment, surface heat treatment, spraying surface, surface treatment is to clean the surface of the workpiece, cleaning, deburring, degreasing, scaling and so on.

Surface treatment belongs to the oldest technology, since there are human beings on the earth, surface treatment is one of the earliest technology mastered by human beings. Primitive human life is extremely difficult, living in a social life, in order to survive, they made stone tools, the use of grinding technology to make stone tools with a sharp edge, resulting in a "wedge" effect. In the Neolithic Age, the stone tools used by the primitive people had become the mainstream of the times because of their fine and smooth surface and decorative effect.

In primitive society, primal painting technology is as important as grinding stone tools. Primitive humans had a sense of beauty, and in the late Paleolithic, they used mineral dyes to paint personal amusements. By the Neolithic Age, the invention of pottery made the original painting technology develop to the peak, forming the famous painting pottery art in history, and opened the prelude of surface treatment painting technology.

In order to remove all kinds of foreign bodies (such as oil, rust, dust, old paint film) attached to the surface of the object, and provide a good substrate suitable for painting requirements, to ensure that the film has good corrosion resistance, decorative performance and some special functions, the surface of the object must be pretreated before painting. The work done in this process is collectively referred to as pre-coating (surface) treatment or (surface) pretreatment.

Such as scrapers, wire brushes or grinding wheels. The rust and oxide scale on the surface of the workpiece can be removed by hand, but the manual treatment has the advantages of high labor intensity, low production efficiency, poor quality and incomplete cleaning.

Mainly uses the acidic or alkaline solution and the workpiece surface oxides and oil stains chemical reaction, causes it to dissolve in the acidic or alkaline solution, achieves removes the workpiece surface rust oxide scale and oil stains, then uses nylon to make the brush roller or 304 # stainless steel wire (acid and alkaline solution made of steel wire brush roller clean and easy To achieve the goal. Chemical treatment is suitable for cleaning sheet metal, but the shortcomings are: if the time is not properly controlled, even if the corrosion inhibitor is added, it can also cause steel corrosion phenomenon. For more complex structural parts and porous parts, after acid solution pickling,

solid surface machine manufacturers of utand is difficult to completely remove the residual acid immersed in the gap or hole, if not properly treated, it will become a worker. It is difficult to discharge chemicals after treatment because of the hidden danger of corrosion, volatile chemicals and high cost. If not properly treated, it will cause serious pollution to the environment. With the improvement of people's awareness of environmental protection, this method is being replaced by mechanical treatment.

The polishing method is that the brush roll is driven by the motor, and the brush roll rotates at a high speed to brush off the iron oxide scale on the upper and lower surfaces of the strip in the direction opposite to the rolling motion. The washed oxide scale is washed away by closed circulating cooling water washing system.

Shot blasting is a method of cleaning and accelerating the projectile by centrifugal force. However, due to the poor flexibility of shot blasting, limited by the site, some blindness in cleaning the workpiece, the inner surface of the workpiece is liable to produce a dead angle that can not be cleaned. The structure of the equipment is complex, and there are many vulnerable parts, especially the blades and other parts wear fast, the maintenance time is too much, the cost is too high, and the one-time investment is too large.

Surface treatment with shot peening has great impact and clear cleaning effect. But shot peening is easy to make the workpiece deformed, and the steel shot strikes the surface of the workpiece (whether shot peening or shot peening) so that the metal substrate deformed.

Because ferrous oxide and ferric oxide have no plasticity, they are broken and peeled off, and the oil film deforms with the workpiece, so shot peening and shot peening on the workpiece with oil stain. Pills can not remove oil completely.
