When the production site uses chloride, fluoride, sulfuric acid or oxalic acid at a concentration of more than 50%, we can only choose ABS sprayed stainless steel eye wash or special treatment of high performance stainless steel eye wash. Because the eye washer made of stainless steel 304 material can resist the corrosion of acids, alkalis, salts and oils in general, but it can not resist the corrosion of chloride, fluoride, sulfuric acid or oxalic acid with concentration above 50%. In the working environment in which the above substances exist, the eyewash produced by using the stainless steel 304 material will have a great degree of damage to the eye wash in less than six months. At present, the ABS spray eyewasher used only solves this technical problem by foreign advanced eyewash manufacturers; only a few companies have this technology for special treatment of stainless steel 304 materials. The use of stainless steel 304 material for ABS spraying or the spraying of stainless steel 304 material, and then the paint method, 1 using ABS powder spray characteristics: ABS powder adhesion strength, thickness of 250-300 microns, corrosion resistance Very strong.
The temperature is determined according to the temperature of the local winter. Except for the southern part of China, other areas will have a temperature below 0 °C in winter. Then there will be water in the eye wash, which will affect the normal eye wash. use. To solve the problem of water accumulation in the eyewash, it is necessary to use an antifreeze evacuation type eye wash. If you use hot water or warm water when your eyes and skin are hurt, it will deepen the corrosion of the wound, causing more serious damage to the injured, but it will be counterproductive. Therefore, it is recommended that users of eyewash users use pure water at room temperature, such as anti-freeze emptying eyewash in East China, Central China and Southwest China. 2. The antifreeze type eye wash device can drain the water in the entire eye wash device after the use of the eye wash device or when the eye wash device is in the standby state.
The antifreeze type eye wash device has an automatic emptying type and a manual emptying type. In general, the automatic emptying type is adopted. For East China, Central China and Southwest China, the frozen ground layer in winter is generally 20-30 cm. The inlet pipe can be insulated to prevent water from freezing in the inlet pipe. The ground-type automatic emptying antifreeze eye washer can be used. The eye wash device can automatically drain the water in the entire eye wash to prevent freezing. For the northeast, north and northwest regions, the frozen ground layer in the winter is generally 50-190 cm. It is obviously impossible to solve the problem of water inlet and antifreeze by using the above-ground anti-freeze type eye wash. The underground automatic evacuation type anti-freeze eye washer must be used. The eye wash device places the antifreeze valve at a position below the frozen soil layer, and uses a switch on the ground to control the water inlet and drainage of the eye wash device, and the eye wash device can automatically drain the water accumulated in the entire eye wash device and the water inlet pipe under the ground to prevent the water from being trapped. freeze.
