What is a duster? What is the powder spray head of the duster

Powder spraying refers to a coating process that uses corona discharge to make powder paint adhere to the workpiece. After powder spraying, it will go through hot melting, curing and other steps to form a coating film on the surface of the workpiece.

In 1954, Germany's James successfully coated polyethylene with fluidized bed method, and in 1962, after the invention of powder electrostatic spraying by France's Sams company, powder coating began to be formally adopted in production.

Powder spraying is the use of corona discharge phenomenon to make the powder coating adsorbed on the workpiece. The process of powder spraying is: the powder spraying gun is connected to the negative electrode, the workpiece is grounded (positive electrode), the powder coating is sent to the spray gun by the powder supply system by compressed air gas, the high voltage generated by the high-voltage electrostatic generator is added at the front end of the spray gun, due to the corona discharge, a dense charge is generated near it, when the powder is sprayed out by the nozzle, the circuit is formed to form a charged coating particle, it is subjected to the action of electrostatic force, and is sucked to the workpiece opposite to its polarity, with the increase of powder sprayed, the more the charge accumulates, when it reaches a certain thickness, Due to the electrostatic repulsion, it does not continue to adsorption, so that the whole workpiece obtains a certain thickness of powder coating, and then the powder is melted, leveled and solidified by heat, that is, a hard coating film is formed on the surface of the workpiece.

Hello, I am happy to serve you and give you the following answers: Powder spraying head has: 1. Spherical powder spraying head:

The spherical powder spray head is composed of a spherical anti-powder valve, a spherical powder nozzle, a spherical powder spray pipe and a spherical powder spraying head, which work together on the powder spraying medium to achieve the effect of uniform powder spraying. 2. Plunger type powder spraying head: The plunger type powder spraying head is composed of a plunger type powder spraying valve, a plunger type powder spraying nozzle, a plunger type powder spraying pipe and a plunger powder spraying head, which act together on the powder spraying medium to achieve the effect of uniform powder spraying.

3. Solenoid valve powder spraying head: The solenoid valve powder spraying head is composed of a solenoid valve, a powder spraying nozzle, a powder spraying pipe and a powder spraying head, and the powder spraying process is controlled by current to achieve the effect of uniform powder spraying. The cause of the problem is generally due to the quality of the powder spraying head itself, or due to improper operation, resulting in uneven powder spraying, or imfine powder spraying.

Solution: 1. Purchase qualified powder spraying heads: When purchasing powder spraying heads, you must ensure that the purchased powder spraying heads are qualified, so as to ensure the uniformity and fineness of powder spraying.

2. Correct operation: When operating the powder sprayer, be sure to follow the correct operation steps to avoid the problem of uneven powder spraying or fine powder spraying. 3. Regular inspection:

When selecting the powder spraying head, it is necessary to choose according to different buried powder spraying media and powder particle size.

Powder spraying method is a method of applying pesticides that use the wind generated by machinery to blow away low-concentration pesticide powder, so that the powder particles float in the air and then deposit on crops and control objects. The powder spraying method is easy to use, has high efficacy, the powder particles are deposited and distributed evenly on the crop, and no water is required, which is more practical in arid and water-scarce areas. However, due to the fact that the powder particles produced by the powder spraying method are easy to pollute the environment, the scope of use of the powder spraying method is increasingly limited.

However, in closed greenhouses, greenhouses, forests with high canopy density, orchards, tall crops, cotton fields and paddy fields in the late growth stage, the powder spraying method is still a better application method.

Powder spraying is electrostatic powder spraying, which is a method of coating.

A printer is a software-controlled device that uses a non-contact method to mark a product. Classified from the consumables used in inkjet printers: one is ink inkjet printers; One is non-ink inkjet printers (laser inkjet printers); From the form of work:

The first type is the first-class inkjet printer, which is mainly used for the production line; A type of mobile inkjet printer is that the sprayed object does not move, and the inkjet is mobile, similar to the handheld inkjet printer on the market. At present, there are imported machines, domestic machines and joint venture machines in the Chinese market. Classification of inkjet printersInkjet printers are classified according to the working principle and divided into continuous inkjet technology (continue

inkjet

Printer) for short, and dropondemand for DOD. Ink-on-demand technology is divided into piezoelectric inkjet technology, pressure-valve inkjet technology, and thermal inkjet technology according to its different implementation methods

inkjet

Technolog), abbreviated as TIJ. Inkjet printer is a high-tech product. Involving many scientific fields, the working principle of inkjet printers is roughly the same, but the technology of each machine is different or slightly different in terms of ink path system, printing system, software control, and electronic system.

Sell inkjet printers. With the rapid development of the economy in recent years, the demand for automation equipment in various industries continues to increase, so that the automatic inkjet printer equipment on the market is generally sold well, can obtain good sales performance, in the inkjet printer equipment is one of the best enterprises in the industry, plays a leading role in the identification industry, so this year, although the potential of the fuel service in the inkjet inkjet Yanna industry has achieved good results, but we will not be proud, the second is to make persistent efforts to lay a solid foundation to find new breakthroughs.

The sales of inkjet printers are, of course, the sale of inkjet printers and inkjet printer consumables.

Don't know what you're trying to ask?

We have been engaged in the inkjet printer industry for 20 years, and we can make some objective statements about the current inkjet printer market.

First, the profits of the inkjet printer industry have fallen a lot, and it has long been rid of the era of "windfall profits".

Fourth, customers are increasingly demanding systematic identification solutions, including anti-counterfeiting traceability system integrated coding and coding equipment, as well as integrated automation equipment. Therefore, now the inkjet marking technology service industry requires you to have the ability to integrate the system, and it is no longer the era when one or two people can dominate the world.

Fifth, the best inferior consumables seriously affect the interests of users, resulting in frequent machine failures. Peers have also seriously affected the profits of inkjet printer service providers, making it difficult for inkjet printer manufacturers to provide good after-sales technical support.

6. Therefore, more and more inkjet printer manufacturers are now tending to develop chip password protection functions for consumables to balance the above impacts.

7. Agree with the answer of the following "enthusiastic netizens", now that the economy is in a recession, it is becoming more and more difficult to make inkjet printers. --Longer and longer payment cycles, more and more accepted payments, more and more bad debts, bad debts, and bad debts.

8. The hot spot of inkjet printer has shifted from the traditional industry (beer, beverage, food) to the mobile phone industry and the first traceability application industry.

It is not easy to do, especially when the real economy is in recession, the inkjet printer business is even more difficult to do.

The most common CIJ inkjet printer on the market, the most common CIJ inkjet printer is the production date CIJ inkjet printer that we can see in canned beer bottles every day! For industrial large-scale packaging, DOD large-character inkjet printers are generally selected.

Wheat. Tyre. That is, because of the wide range of applications of inkjet printers, there are more manufacturers.

Didn't you ask about this? There are Hongtaida inkcast printers in Jinhua, and the headquarters is in Shenzhen.
