Is printing powder spraying harmful to the body, and is the powder spraying process toxic

The harm of printing powder spraying to the human body:

Susceptible to respiratory diseases

It will be harmful to the human brain, lungs, eyes, and reproductive health.

Bad damage to**luster.

Although powder spraying is not very toxic to humans, if the inhalation amount is large and for a long time, you may get lung disease, such as pneumoconiosis.

Wait. The role of printing powder spraying:

Printing powder is an indispensable tool in offset printing! The printing powder sold on the market is mainly pure.

Plant-based substances are used as basic raw materials, and commonly used materials are flour, corn flour (corn flour), vegetable starch, and tapioca flour.

Wait. Its main function is to prevent the back of the printed matter from sticking to dirt during the printing process and speed up drying.

The printing powder used now is made of environmentally friendly materials, which is harmless to the human body, and many mice will steal it.

Of course, absorbing too much of anything will be bad for the human body. Because of the machine, we have to use powder spraying, which is a process problem, and we have no ability to change it for the time being, so we can only find ways to reduce its harm to the human body.

For example, reducing the amount of powder sprayed, reducing the amount of ink used, and installing a vacuum on top of the delivery table, etc., I hope it can help you.

Brother is too powerful, I open CD102 to print 100,000 a day, and I use 3 packs of powder at most. Powder spraying itself is non-toxic, but inhaling too much is not good for the lungs and will cause pneumoconiosis. It's best to wear a mask when you open such a big powder.

Summary. It is not toxic and is produced in accordance with national standards. Powder spraying is the use of corona discharge phenomenon to make the powder coating adsorbed on the workpiece. Clause.

1. Spraying pretreatment: spray multi-station pretreatment unit is a commonly used equipment for surface treatment, and its principle is to use mechanical scouring to accelerate chemical reactions to complete degreasing, washing and other processes. The shot blasting machine can also be used for pre-treatment, which is suitable for steel parts with simple structure, serious rust, no oil or less oil.

The environmentally friendly chemicals used are free of phosphorus, heavy metals, and water pollution. Clause.

2. Powder spraying system: The filter element of the large cyclone powder spraying room in powder spraying is a powder device with more advanced and faster color change. The powder can be used without powder overflowing, so you don't have to worry about the powder flying all over the sky. Clause.

3. High temperature curing: The oven is an important part of the powder spraying production line, and its temperature uniformity is an important indicator to ensure the quality of the coating. The hot air circulation oven has good heat retention, uniform temperature in the furnace, less heat loss, and the temperature difference in the furnace is less than 3 after testing, so as to reach the performance indicators of similar products in advanced countries.

Is the dusting process toxic.

It is not toxic and is produced in accordance with national standards. Powder spraying is the use of corona discharge phenomenon to make the powder coating adsorbed on the workpiece. Clause.

1. Pretreatment of spraying fiber group: spray multi-station pretreatment unit is a commonly used equipment for surface treatment, and its principle is to use mechanical scouring to accelerate chemical reaction to complete the process of degreasing and washing. The shot blasting machine can also be used for pre-treatment, which is suitable for steel parts with simple structure, serious rust, no oil or less oil.

The environmentally friendly chemistry used to destroy the orange substance has no phosphorus, no heavy metals, and no water pollution. Clause.

2. Powder spraying system: The filter element of the large cyclone powder spraying room in powder spraying is a powder device that is more advanced and has a faster color change. The powder can be used without powder overflowing, so you don't have to worry about the powder flying all over the sky. Clause.

3. High temperature curing: The oven is an important part of the powder spraying production line, and its temperature uniformity is an important indicator to ensure the quality of the coating. The hot air circulation oven has good heat retention, uniform temperature in the furnace, less heat loss, and the temperature difference in the furnace is less than 3 after testing, so as to reach the performance indicators of similar products in advanced countries.

Clause. 4. Heat source system: hot air circulation is the most commonly used heating method, which uses the principle of convection conduction to heat the oven to achieve the drying and curing of the workpiece.

The mu sui circulating fan is a special high-temperature resistant fan, which has the advantages of long life, low energy consumption, low noise and small size. Clause.

5. Electronic control system: the electrical control of the powder spraying production line has centralized and single control. Centralized control can use programmable controller to control the host, and automatically control, collect data and monitor and alarm each process according to the prepared control program.

Single-row control is a commonly used control method in the coating production line, each process is single-row mu sales-resistant control, and the electric control box is set near the equipment, with low cost, intuitive operation and convenient maintenance. Clause.

6. Suspension conveyor chain: the suspension conveyor is the conveying system of the powder spraying production line, and the workpiece is hoisted on the special hanger to meet the automatic transportation of the workpiece at each processing station.

Powder spray printers are non-toxic, but the ink used is poisonous.

The ink of the powder spraying machine contains many harmful substances, including harmful metals such as mercury, cadmium and hexavalent chromium, which can cause lung damage and tumors if inhaled. In the production of domestic inkjet ink, black dye ink mostly uses direct dyes, and color inks mostly use acid dyes and reactive dyeing dry culture. Direct black dyes generally contain benzidine compounds that are highly carcinogenic, and benzidine has an incubation period of 10 to 20 years in humans.

Lawyer Analysis: Pollution. Printing plants discharge, dump or dispose of radioactive wastes, wastes containing infectious disease pathogens, toxic substances or other hazardous wastes into land, water bodies and the atmosphere, thus causing major environmental pollution accidents.

Legal basis]:
