Why is it recommended to use automatic light changing welding mask when welding?
Because there are many kinds of harmful substances produced by welding operation, metal elements, welding flux, under the action of high temperature flame will produce a variety of harmful substances and welding smoke, endangering the health of workers, the most common occupational diseases are welder pneumoconiosis and metal smoke heat.
The main form of transmission is through the inhalation of welding smoke into the lungs to endanger the health of workers, the choice of variable light electric welding mask can effectively prevent the inhalation of welding smoke.
Electric welding is an indispensable important processing technology in modern industrial production and equipment maintenance. in shipbuilding, container production and other industries, mechanical processing industry, welding is a high-density operation, electric welding as a special operator, it is very important to understand the respiratory hazards that lead to occupational diseases and to choose a safe and effective photovoltaic welding mask.
Extended data:
The respiratory protection of welders should be combined with the characteristics of operation.
When working in the open air, the harmful substances produced by welding will not accumulate in high concentration and the harm is relatively mild.
In high-density work in small or large spaces, the concentration of harmful substances will reach a very high level. As the last line of defense to protect workers’ health, individual respiratory protection can not only be effective, but in many cases, compared with ventilation facilities, the cost of individual protection is also lower.

How to install stainless steel gas mask?
Fix the hanging board of the tobacco machine: drill the hole in the installation position and use Phillips screws to fix the hanging board of the tobacco machine attached to the packing box to the wall
2. Hang the smoke machine on the hanging board: hang the range hood on the hanging board to ensure that the range hood does not sloshing and decoupling and ensure the level as far as possible.
3. Install the smoke exhaust pipe: connect one end of the smoke exhaust pipe to the air outlet on the range hood, and the other end to the common flue or the wall hole on the outer wall. If the smoke is discharged to the common flue, do not insert the smoke exhaust pipe too deep to increase the smoke exhaust resistance. If the smoke is discharged outside the wall, it is recommended to install louvers outside the smoke exhaust pipe. At the same time, be sure to make the smoke exhaust pipe mouth protruding 30mm to avoid recharge.
4. Install the oil cup: screw the oil cup or push it into place and fix it.
I hope my answer will be helpful to you. According to the number of ventilation to determine the exhaust air volume: the kitchen varies greatly, the kitchen area is not proportional to the number of kitchen utensils and stoves, and the pollutants and heat produced by the same stove are also very different. In fact, kitchen ventilation is not comprehensive ventilation, according to the number of air exchange design air volume will have a great error.
(2) Design exhaust air volume according to the amount of pollutant emission: environmental protection GB18483-2001 Catering Industry Oil Fume Emission Standard stipulates that each stove needs air volume 2000m3/h. The author thinks that there are still limitations in designing air volume according to this method. In fact, the actual situation of the catering industry is complicated: the size of the stove, the stove has Cantonese style, Soviet style, etc.; in addition to the stove, there are soup pots, bowls, steamer ovens, etc.; functionally, there are cooking rooms, cooking rooms, pastry rooms, barbecue rooms, western food processing rooms, washing rooms, etc., and the amount of heat and pollutants is not dissipated.
What are the four major mechanical structures of cars? What are their functions?
Hello, the four major machinery are divided into: engine, chassis, body and electrical equipment.
Automobile engine: the engine is the power plant of the car. It is composed of two major institutions and five major systems: crank-connecting rod mechanism; valve mechanism; fuel supply system; cooling system; lubrication system.
Chassis of the car: the function of the chassis is to support and install the engine and its components and assemblies, form the overall shape of the car, and accept the power of the engine to make the car move and ensure normal driving.
How to clean the silicone mask with a little sticky surface?
First of all, after we have finished the production of silica gel products, we will pack them in boxes and wrap them with dust-free clothes. if the products need to be stored for a longer time, we need to use film bags to prevent the surface of silica gel products from sticking to dust and ensure the appearance quality of the products.
In view of the phenomenon that the surface of silicone products is easy to adhere to dust, our silicone products factory usually advises customers to spray hand oil, which is a kind of oily substance that can adsorb the surface of silica gel, which can increase the smoothness of the surface of silicone products. isolate the contact between the outside world and the silica gel surface, and really achieve the effect of preventing silica gel products from adhering to dust. What if a large number of silicone products are accidentally stained with dust? We can deal with it in the following ways
1, slight dust can be wiped without dust cloth, and so on can be effectively removed
2. Serious dirt and dust can be wiped with white electric oil, or directly soaked in white electric oil liquid and then wiped with a clean clean cloth
How to tell whether the welding mask is good or not?
Ten ways to distinguish between good and bad welding masks
1. Buy the products with the inspection report of China Labor Protection products quality Supervision and Inspection Center or authoritative certification (CE,ANSI certification). The purchased products can only be used after acceptance.
2, automatic change photoelectric welding mask should not be stored in: acid, alkali, high temperature, sun, moisture and other places.
3. The service life of automatic light changing welding mask. Inferior products have no test report and certification, cheap price, short service life, unstable light not only can not block red ultraviolet rays, but also force the pupils to dilate, resulting in a large number of red ultraviolet rays, causing eye burns.
4. How to buy a real quality automatic light-changing welding mask whose retail price is too low to be a qualified product at all.
5, perfect after-sales service, (no artificial damage and appearance problems), two-year warranty.
6. The safety and technology department of the enterprise shall carry out spot check and test for the expired automatic light-changing electric welding mask, and it can continue to be used only after it is qualified, and it will be scrapped if it fails to pass the inspection.
7. Confirm that the goods are the products you purchased, and carefully check and make sure that all the accessories and instructions in the package are complete.
8. The products loaded into the box of the electric welding mask are all qualified products after inspection.
9. Welding masks all goods are packed in color boxes and outer boxes, and each cap is padded with plastic film and put into color box packaging.
10. The outer packing box shall be marked with product name, quantity, weight, volume and other matters needing attention.
So much for the introduction of the mask box. Thank you for taking the time to read the contents of this site. Don’t forget to look for more information about the mask box and the mask box on this site.
