TT car model electrostatic paint technology?


The process of baking paint is by grinding onto a base with a certain roughness, and entering the vacuum baking room to spray some paint. After baking and setting at high temperature.
By using an electrostatic powder spraying equipment (electrostatic spray machine) the powder coating is sprayed onto the surface of the car model, under the electrostatic interaction, the powder will be uniformly adsorbed on the surface of car model, the formation of powder coating; powder coatings after high temperature baking leveling curing, into effect (different effect of different kinds of powder coatings) the final coating; the spraying effect in the model strength, adhesion, corrosion resistance, aging resistance and superior cost in spray painting process, under the same effect.
Electrostatic spraying is a kind of spraying method which uses a high voltage electrostatic electric field to make the negatively charged coating particles move in the opposite direction of the electric field and adsorb the coating particles on the surface of the car model. Electrostatic spraying equipment consists of spray gun, spray cup, electrostatic spraying and high voltage power supply.
When the electrostatic spraying gun or spray disc, spray cup, paint particles part is connected to the anode, the work piece is connected with the anode and the ground, in the role of the high voltage and high voltage power supply under the gun (or spray, spray cup disc) between the tip and the car model can form an electrostatic field. The charge voltage and the paint particles coating particles by electric field force and electrostatic field is proportional, and inversely proportional to the distance between the gun and the model, when the voltage is high enough, the formation of air ionization zone near the lance tip, air ionization and intense heat, the lance tip or extremely sharp edges around the needle a dark red halo, can clearly see in the dark, when the air generated strong corona discharge.
The coating was atomized spray paint particles by atomization muzzle or spray needle plate, spray the rim for contact and charged, when the gas ionization zone generated by corona discharge, will once again increase the surface charge density. These negatively charged coating particles act as electrostatic guides to the surface of the workpiece and are deposited on the surface of the car model to form a uniform coating.
Hope you like, and after a lot of attention to us (TT diecast models cars ), thank you read!

Car model appreciation

The proportion is the most basic, different proportions of the production process and the number of spare parts are also very different. Followed by the details of the same static simulation of the car model , the details of the difference is enough to form a huge difference between the products, naturally also formed a huge difference between the price of the brand. How to go through the details to identify the quality of the car model quality and grade of the level of the following methods can let you have a basic way to identify: weigh the weight, guess parts, paint, knowledge, see the door, listen to the sound, Check the details, gaps, lights and windows, chassis, engine, interior, tires and wheels, etc., these methods look nothing, when you actually will find one of the differences, I think there should be a lot of friends Has been doing it! During the period do not understand or want to know the specific content, you can give me a message! Finally, we talk about auth...

Car model drawings

Car models are divided into 2D drawings and 3D drawings. 2D drawings: simply 2D is a linear plane diagram, there is a line to the vehicle shape, interior details, tires and other sketches out, just like the painting of the same picture, but the 2D linear chart of each line are with Data, so when drawing 3D drawings, if the import 2D map, the designer can be based on these lines of data to describe the design. Although it still takes some time, but compared to pure picture reference design, whether it is time or simulation accuracy is much higher. 3D drawings: Tong Tong model is generally used PROE software for 3D design, 3D design, also known as three-dimensional design, is a new generation of digital, virtual, intelligent design platform based. He is based on the plane and two-dimensional design on the basis of the design goal more three-dimensional, more visualized a new design method, just like a 3D movie is a meaning. When the customer can provide the 3D map to t...
