Electroplating, hot plating, spraying, dipping, respective advantages and disadvantages and collocat

Electroplating and hot plating are mostly coated with a layer of metal, while spraying and dipping are coated with a layer of plastic film. The first two have a metallic feeling, high surface hardness, decoration, wear resistance, electrical conductivity, impact resistance, etc., and the spraying and dipping metal sense is poor, and the insulation is good. The difference between electroplating and hot plating is that electroplating is to deposit metal on the plated parts with the help of DC power supply in the electrolyte, while hot plating is that the plating parts attach a layer of metal to the molten metal liquid, the electroplating layer is often much thinner than the hot plating, and the plating layer is not as uniform as the hot plating, and the corrosion resistance is poor, but the appearance of the hot plating is not as good as that of electroplating.

The difference between spraying and dipping is that spraying is to adhere the plastic powder to the surface of the workpiece with the help of static electricity, and then heat melt it into a film, dipping is directly immersed in the molten or solvent-dissolved plastic to form a film, and there are also preheating the workpiece first, immersing it in the blown plastic powder, sticking a layer of plastic powder, and then heating and melting it into a film. The four processes are commonly used anti-corrosion decoration processes, each with its own merits and advantages, and if electroplating and plastic coating are combined, the corrosion resistance can be further improved.

Red, blue, white, black, gray, yellow. Each process has its own advantages, such as large dipping thickness, good spray adhesion, large choice of electrophoretic colors, long salt spray time, wide selection of paint colors, good paint toughness, and beautiful electroplating appearance.

Plating is the electroplating solution (solution) by the electrodetic electrode by the electrode voltage to force metal ions adsorbed on the plating part.

Hot plating is to dissolve the metal by heating, and then add the surface treated plated parts to the metal dissolution tank, so that the molten metal attaches a layer to the surface of the plated parts, and the curing treatment can be done.

Spraying is the use of high-pressure air flow to spray powdered metal powder or other paint powder onto the workpiece, sometimes heating and curing, it can be.

Dipping is to immerse the surface treated workpiece directly into the plastic liquid, take it out and solidify it.

Different processes are used for different workpiece machining needs.

First, the principle is different.

1. Galvanizing is searching: hot-dip galvanizing is to make the molten metal react with the iron matrix to produce an alloy layer, so that the matrix and the coating are combined.

2. Painting: Spraying through a spray gun or disc atomizer, with the help of pressure or centrifugal force, dispersed into uniform and fine droplets, applied to the surface of the coated coating method. 3. Baking paint:

On a substrate that has been sanded to a certain degree of roughness (usually high-density sheets), several layers of paint are sprayed. And it is baked and shaped at high temperature.

4. Spraying: Its working principle is to charge the plastic powder through high-voltage electrostatic equipment, and spray the paint to the surface of the workpiece under the action of the electric field, 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 final protective coating with different effects; Firmly adheres to the surface of the workpiece.

5. Dipping: Most of the liquid dipping process uses thermoplastic dipping liquid, and the thermoplastic coating film has the characteristics of preheating and softening, and can be solidified after cooling.

Second, the application is different.

1. Galvanizing: widely used in automobiles, construction, home appliances, chemical industry, machinery, petroleum, metallurgy, light industry, transportation, electric power, aviation and marine engineering and other fields.

2. Painting: It has a wide range of applications, involving various sectors of the national economy and various fields including cutting-edge technology.

3. Baking paint: mainly used in solid wood furniture industry, industry and other aspects.

4. Spraying: It is often used in the field of light industry and home decoration.

5. Dipping: Dipping products have been widely used in all aspects of production and life at home and abroad, such as hangers for drying clothes, pliers, rubber sleeves on scissors, wrenches for water valves, etc.

Third, the advantages are different.

1. Galvanizing: The hardness value of the galvanized layer is greater than that of steel; The entire surface of the steel is protected and melted zinc is easily and evenly covered in recesses, inside the fittings, or in any corner where other coatings are difficult to access.

2. Painting: Spraying operation has high production efficiency and is the most commonly used coating method today.

3. Baking paint: the paint has high requirements and good color rendering.

4. Spraying: no thinner material is required, and the construction is non-polluting to the environment and non-toxic to the human body; The coating has excellent appearance quality, strong adhesion and mechanical strength; Short curing time for spraying construction; The corrosion and wear resistance of the coating is much higher; No primer required; The construction is simple and the technical requirements for workers are low; The cost is lower than that of the painting process. Stove.

5. Dipping: the material is rich, cheap and non-toxic; Wide range of color configurations; The coating film has strong adhesion, low temperature resistance, impact resistance, wear resistance, damp heat resistance, salt spray resistance, tensile resistance, acid and alkali resistance, aging resistance, high pressure resistance, chemical resistance, excellent weather resistance, and will not produce cracks when used in the open air.

Summary. Most of the liquid dipping process uses thermoplastic dipping liquid, and the thermoplastic coating film has the characteristics of preheating and softening, and can be cured to form a film after cooling. The most typical and commonly used is polyvinyl chloride (PVC) impregnated plastic liquid, which is a synthetic raw material mixed with more than 10 kinds of advanced additives and additives with polyvinyl chloride (PVC) in strict accordance with the ratio, and is refined by reaction after Seiko mixing.

My dear, I am honored to be able to serve you, I have seen the mess of your question, it will take a while to type, please wait a while, I am working hard to sort out the answer for you, and I will reply to you within five minutes

Dear, hot-dip galvanized polyester composite coating is dip-plastic.

Dip plastic alias is also known as plastic coating, hot dip plastic, hot compress plastic. Dip (coating) flame retardation is a plastic coating process. According to the different raw materials used in dipping, it can be divided into liquid dipping (taking envy coating) plastic and powder dipping (coating) plastic pie.

Dipping products have been widely used in all aspects of production and life at home and abroad.

Most of the liquid dipping process uses thermoplastic dipping liquid, this spring thermoplastic lead hole coating film has the characteristics of preheating and softening, and can be cured to form a film after cooling, and the main physical melt plasticization film forming process, processing and production are relatively simple. The most typical and commonly used is polyvinyl chloride (PVC) impregnating liquid, which is a synthetic raw material mixed with more than 10 kinds of advanced additives and additives with polyvinyl chloride (PVC) in strict accordance with the ratio, and is refined by reaction after Seiko mixing.
