Embodiment Construction

[0020] In the following, the present invention will be further described in conjunction with the examples. The production method of the natural mineral adsorption filtering electric welding mask is as follows:

[0021] The production method of natural mineral absorption filtering electric welding mask (1) is to add natural mineral absorption filtering agent (3) moistened with water into the mask mold, press to form the rough of natural mineral absorption filtering electric welding mask (1), and send it into Dry naturally in the drying room. When the moisture content of the blank is less than 15%, the blank is transported to the roasting kiln for roasting. The roasting time is 15 hours, and the roasting temperature is controlled at 350-400℃. After cooling, it will adsorb natural minerals. Filter the semi-finished products of the welding mask; inlay a U-shaped stainless steel frame (8) around the periphery of the semi-finished product, and install a handle (10) at the bottom end of ...

Abstract

The present invention relates to a production method of natural mineral adsorption filtration electrowelding face cover. Said production method uses natural mineral adsorption filtration agent as raw material, and includes the following several steps: moistening said raw material by adding water, moulding to obtain the blank of said electrowelding face cover, drying baking, cooling, mounting edge frame and mounting handle, and packaging so as to obtain the invented product.

Description

Technical field [0001] The invention relates to a face mask, in particular to a production method of a natural mineral absorption filtering electric welding face mask. Background technique [0002] Under the action of the high temperature and strong ultraviolet rays generated by the welding arc, a large amount of toxic gas will be generated around the arc area. The arc light generated by welding mainly includes infrared rays, visible light and ultraviolet rays. Among them, ultraviolet rays are mainly harmful to the human body through photochemical action. It damages the eyes and bare skin, causing keratoconjunctivitis (electric ophthalmia) and skin biliary erythema. The main manifestations are eye pain, shame, tearing, eyelid swelling and spasm. After ultraviolet radiation, the skin may have obvious edematous erythema. In severe cases, blisters, exudates and edema may appear, and there is a clear burning sensation. [0003] While melting the welding rods and weldments, a large am...
