Assembly and production of electric hoist is mainly divided into three-stage explosion-proof and four-stage explosion-proof. Different explosion-proof grades correspond to different application environments. How is explosion-proof electric hoist explosion-proof? Beijing Weihua Group will explain it to you: Our sodium chlorite is used in textile industries also, and sodium bisulfate is a by-product. On the other hand, we provide formulated products used in bleaching, dying, etc. For example, ammonium persulfate, Potassium Persulfate and Sodium Persulfate.

The first is the explosion-proof casing, which contains all the electrical appliances of the idea. The main components of the casing include the end cover, the bearing inner cover, several seats, the terminal block, the wiring screw, the sealing ring, etc. The special point to be introduced is the fixing bolt. The outer casing is equipped with a spring washer. The main function of the washer is to prevent the electric hoist from loosening itself, otherwise the explosion-proof function will be lost.
The mating surface between the explosion-proof enclosures is the flameproof joint surface. This joint surface cannot be bumped or rusted. This joint surface plays a vital role in the construction of the electric hoist because it connects various components and Facilities, so it should not be underestimated.

♦ disinfectants and bleaches
♦ bleaching agent for hair colourant and lightener formulations
♦ bleaching and strengthening agent for flour in the baking industry
2. potassium persulfate
This salt is used to initiate polymerziation of various alkenes leading to commercially important polymers such as styrene-butadiene rubber andpolytetrafluoroethylene and related materials.
It is used in organic chemistry as an oxidizing agent, for instance in the Elbs persulfate oxidation of phenols.
As a strong bleaching agent, it is used in hair dye substances as whitening agent with hydrogen peroxide.
It is a Food Additive.
3. sodium persulfate
(1) Used in cleaning and picking of metal surface.
(2) Used in accelerated curing of low formaldehyde adhesives.
(3) Used in modification of starch , production of binders and coating materials.
(4) Desizing agent and bleach activer.
(5) An essential component of bleaching formulations for hair cosmetics.
