Select the eye washer to pay attention to what conditions

First: According to toxic and hazardous chemicals on the job site

When using the presence of chloride, fluoride, sulfuric acid or oxalic acid at a concentration of more than 50%, only stainless steel eyewashers impregnated with ABS or high-performance stainless steel eyewashers with special treatment can be selected. Because the eye wash device made of stainless steel 304 material can resist the corrosion of substances such as acid, alkali, salt and oil under normal conditions, but it can not resist the corrosion of chloride, fluoride, sulfuric acid or oxalic acid with the concentration over 50%. In the working environment in which these substances are present, the use of stainless steel 304 eyewash device, less than six months, the eyewash will have a great deal of damage.

At present, with the ABS eye washer, only foreign advanced eyewash manufacturers have solved this technical problem; only those who use stainless steel 304 for special treatment have this technology. The use of stainless steel 304 material for ABS spray or stainless steel 304 material spray paint, and then paint the method is not resistant to corrosion.

The concept of ABS dip and ABS spray is not the same. ABS dip is made using ABS powder dip instead of ABS liquid dip.

1. Features of ABS powder impregnation: ABS powder has strong adhesion strength, thickness of 250-300 microns, and strong corrosion resistance.

2, the use of ABS liquid impregnation characteristics: ABS powder adhesion strength is poor, the thickness of 250-300 microns, corrosion resistance is very strong.

Second: According to the local winter temperature

At present, except in southern China, other regions will experience weather below 0°C in the winter, and there will be stagnant water in the eyewash, which will affect the normal use of the eyewash.

To solve the problem of water accumulation in the eyewash, you must use anti-freeze eyewash, electric hot eyewash or electric heated eye wash.

1. The anti-freeze eyewash device can empty the entire eyewash device when the eyewash device is used or when the eyewash device is in standby condition. Anti-freeze eyewashers have automatic emptying type and manual emptying type. Under normal circumstances, automatic emptying type is used.

For East China, Central China, and Southwest China, the permafrost in the winter is generally 20-30 cm. The water inlet pipe can be insulated to prevent water from freezing in the inlet pipe. You can use the above-ground type to automatically empty the anti-freeze eyewasher. The eye washer can automatically drain the water inside the entire eye washer to prevent it from freezing.

For the northeast, north, and northwest regions, the permafrost layer in winter is generally 50-190 cm. The use of above-ground anti-freeze eyewashers is obviously unable to solve the problem of water ingress and freeze protection, and buried-type automatic emptying antifreeze eyewashers must be used.
