The utility model relates to an acid liquid bath, in particular to an acid liquid bath specially used in the production process of latex gloves.
During the production of latex gloves, calcium carbonate powder remains in the glove mold, which needs to be cleaned in an acid bath.The acid used is usually the dilute hydrochloric acid solution with a mass fraction of 4%.Acid tank body can be made of stainless steel or plastic, stainless steel is easy to be corroded by acid, affecting the service life;Although plastic does not react with acid, it is prone to aging. Affected by waste heat of glove mold, the acid temperature in the acid bath is generally 50°C_90°C, which accelerates the aging process of plastic.Therefore, the use of these two tank is not ideal.
The utility model aims to provide a special acid bath in the production process of latex gloves. The bath body adopts multi-layer anticorrosive structure, which can resist the long-term corrosion of dilute hydrochloric acid solution in the acid bath.At the same time, the bottom of the tank is provided with a number of liquid replacement holes to facilitate the replacement of acid in the tank.
The utility model is realized through the following technical scheme:
A special acid bath used in the production of latex gloves is characterized by: the tank body is composed of stainless steel tank body, graphite coating, carbon fiber cloth and ceramic coating successively from outside to inside. The thickness of stainless steel tank body is 10-15_, the thickness of graphite coating is l_2mm, the thickness of carbon fiber cloth is 4-6mm, and the thickness of ceramic coating is 2-3mm.The bottom of the tank body is provided with 4 liquid changing holes.
The double-layer anticorrosive structure of graphite coating and ceramic coating is adopted, which can enhance the resistance ability of the tank to corrosive substances such as dilute hydrochloric acid and chemicals produced after cleaning the mold, protect the tank from being corroded by it, and improve the service life of the acid tank.In the process of use, if the ceramic coating is corroded, corrosive substances will enter the carbon fiber cloth layer instead of directly contacting the graphite coating. At this time, the carbon fiber cloth can be used as a buffer medium to protect the graphite coating. At the same time, the carbon fiber cloth also has a heat insulation effect to prevent workers from touching the acid tank and causing scald accident.Acid tank in dilute hydrochloric acid to use after a period of time needs to be replaced, but the acid tank for rectangular tub, change when acid is not easy to pour, the utility model has in liquid hole at the bottom of the tub, replacing acid liquid will in open hole, waste acid from the hole in fluid flow, after waiting for waste acid emptying shut in fluid hole, to add new acid, acid tank, simple and convenient operation, can greatly save manpower.
Beneficial effect: the utility model adopts double-layer anticorrosive structure, which has better anticorrosive effect, can resist the long-term corrosion of acid liquid and prolong the service life of acid liquid tank;At the same time has the heat insulation effect, may prevent the worker to contact the tank body to produce the scalding accident;And acid replacement convenient, can save manpower and material consumption.
