What is cold rolled sheet spraying? What is cold spraying

Plastic spraying refers to the use of an electrostatic generator to electrify plastic powder, which is a surface treatment that sprays plastic powder on parts.

Method. Plastic spraying is what we often call electrostatic powder coating.

Painting, its treatment process is a more common metal surface treatment decoration technology in the world since the 80s of the 20th century. Compared with ordinary paint surface treatment, the advantages of this technology are reflected in advanced technology, energy saving and high efficiency, safety and reliability, and bright color.

Therefore, it is often used in the field of light industry and home decoration. Its working principle is that the plastic powder is charged through high-voltage electrostatic equipment, and under the action of the electric field, the paint is sprayed on the surface of the workpiece, and the powder will be evenly adsorbed on the surface of the workpiece to form a powdery coating; The powdered coating is leveled and cured after high-temperature baking, and the plastic particles.

will melt into a dense layer of final protective coatings with varying effects; Firmly adheres to the surface of the workpiece.

What is spraying.

Spray coating (also known as spray porcelain coating, multilayer pattern coating, relief coating, gorgeous spray brick, Boon spray brick) is an aggregate architectural coating with organic polymer or organic material and silica sol and other inorganic materials as the main film-forming substance. Commonly used organic polymers include styrene acrylic emulsion, pure acrylic emulsion, epoxy acrylic emulsion, vinyl acetate-ethylene copolymer emulsion, water emulsion epoxy resin, etc. Rutile titanium dioxide, lithopone, zinc oxide, talc, mica powder, quartz powder and fibrous materials such as asbestos wool are commonly used in mixed fillers.

The variety and dosage of additives depend on the binder. l)~'af"mt oq

According to the construction characteristics of spray coating and the role of different levels, the coating structure can be divided into three parts: p

1) Primer (primer, primer).

{ZQ FMDKI-MASS-SPC, SIX SIGMA, TS16949, MSA, FMEA Primer is the first coating to be applied to the base layer. It penetrates into the substrate to enhance the strength of the substrate, and at the same time seals the surface of the substrate, and eliminates the factors that are detrimental to the adhesion of the substrate surface, increasing the adhesion between the skeleton and the substrate.

The middle coating is a unique molding layer of spray coating, which is the main component of spray coating. A special large-caliber spray gun is used to spray on the primer, and then rolled to form a three-dimensional pattern with a plump texture and novel beauty. The skeleton has sufficient bonding strength to reinforce the building.

At the same time, the skeleton is the main component of the spray coating, which increases the durability, water resistance and strength of the spray coating. Six Sigma Quality Forum ZF2M7QCH-E

3) Topcoat (topcoat, topcoat).

V7 FY B Six Sigma Quality Forum Topcoat is the surface layer of spray coatings. The face oil is filled with a variety of light-resistant color pigments to make the spray coating have a soft color. According to the different needs of indoor and outdoor, it can be sprayed into a light and flat coating.

The face oil plays a role in beautifying the appearance of the spray coating and improving the durability of the coating.

Painting and spraying are the main ways to decorate industrial surfaces today. In order to protect the environment, spraying was invented in 1982, and after 20 years of development, no more than 5% of enterprises now use spraying. Mainly due to the difference between painting and spraying:

Spraying is what we often talk about electrostatic powder spraying, which is the use of an electrostatic generator to make the plastic powder charged, adsorbed on the surface of the iron plate, and then after 180 220 baking, the powder melts and adheres to the metal surface. Spraying powder mainly includes acrylic powder, polyester powder, etc.

Our company provides heat treatment for spray processing.

Cold-rolled plate spraying: Plate spraying pants made of hot-rolled coil as raw material and rolled at room temperature below the recrystallization temperature.
