As we learn more about new coronaviruses, we should choose to wear masks to protect ourselves from coronavirus infections. N95 masks can effectively block the spread of new coronaviruses. If you do not need close contact with the patient or high risk often occurs, you can use it multiple times before the N95 mask is not damaged or dirty. However, N95 masks have a certain life span. As the use time of the N95 mask increases, the filtered particles will gradually block the filter and the respiratory resistance will increase. If used for a long time, the internal "humid climate" may breed bacteria, and the method of use and storage will affect the life of the mask. N95 masks are usually used for 24-48 hours.
N95 masks have medical standards and can filter tiny virus-borne aerosols or harmful dust particles. They have excellent filtering performance. The filtration efficiency of particles as small as 0.1 microns can reach 99.8% and can be adjusted to adapt to different facial types. To reach a very high level. Cooperation can effectively protect our safety.
Precautions for use:
1. Wash your hands before wearing a mask, or avoid touching the inside of the mask when wearing a mask to reduce the possibility of the mask being contaminated.
2. Clearly distinguish the inside, outside, top and bottom of the mask.
3. Do not squeeze the mask by hand. N95 mask can only isolate the virus on the surface of the mask. If you squeeze the mask by hand, the virus will wet the droplets on the mask, which can easily cause virus infection.
4. Try to make the mask and face have good adhesion. The simple test method is: after putting on the mask, exhale hard, and the air cannot leak from the edge of the mask.

Shot blasting machine is generally used for regular shapes, etc., several blasting heads are up and down, left and right, high efficiency and low pollution. In the shipbuilding industry, shot blasting and sand blasting machines are commonly used. However, both the shot blasting machine and the sand blasting machine uses compressed air. Of course, it is not the floor shot blasting machine that has to use a high-speed rotating impeller. In shipbuilding and shipbuilding industries, floor shot blasters are generally used for steel plate pretreatment (removal of rust before painting); shot blasting equipment (ores used in repairing and shipbuilding industries) are mostly used for shaped ships or sub-parts. The function is to remove the old paint and rust on the steel plate and repaint it. In the shipbuilding and shipbuilding industry, the main function of shot blasting equipment and automatic sandblasting machine is to increase the adhesion of steel plate coating paint. In fact, t...
water well drilling rigs Water well drilling rigs are easy to move, small in size, and high in work efficiency. They are fully hydraulically controlled for lifting, outriggers, lifting, and other processes. Drill pipes can be replaced without stopping the machine. It can meet various geological conditions such as soil, well-drilling sand, and rock pebble layers. Structure, equipped with high-power hydraulic motor, high torque, fast drilling speed. Water well drilling machine is suitable for complex formations such as soil layer, rock layer, pebble layer, cemented pebble layer, etc. Water well drilling rigs are widely used in foundation engineering construction of high-rise buildings, large bridge projects, water conservancy construction, farmland engineering, and other fields. Small water well drilling rigs are suitable for building pile foundations, high-tension line tower pile foundations, dam foundation drilling, drilling water wells, agricultural irrigation wells, and engin...
Nitrile gloves are mainly made by dipping nitrile latex, molding, vulcanizing, surface treatment, dust-free cleaning, and other processes. The specific production process is as follows: First of all, the material for making nitrile gloves is nitrile rubber, which is formed by the emulsion polymerization of butadiene and acrylonitrile. Then, the hand-washing mold: the hand-washing mold needs to be pickled first, washed first, alkali washed, and then washed. After washing the hand mold, it should be dried or dried before entering the next process. The third step is to impregnate the nitrile latex to shape the glove. That is, the hand mold is immersed in a container filled with nitrile, heated at a high temperature, and dried after forming the glove. Next, we need to prepare the gloves to curl to facilitate putting on and taking off the gloves. After the above steps, the nitrile glove has been formed, but it has not been successful. A key step is needed: chlorine washing. Chlorine cleani...
