Embodiment Construction
[0020] Below in conjunction with embodiment, the present invention is further described, and the production method of natural mineral adsorption filter mask is:
[0021] Add the natural mineral adsorption filter agent moistened with water into the mask mold, use a press to press the blank of the natural mineral adsorption filter mask, and send it to the drying room for natural drying. When the water content of the blank is less than 15%, put The blank is transported to the roasting kiln for roasting. The roasting time is 12 hours, and the roasting temperature is controlled at 300-350 ° C. After cooling, it is a semi-finished product of natural mineral adsorption filter mask: 4 through holes (5) are drilled on the front of the semi-finished product. The hole (5) has a diameter of 4 mm.
[0022] The natural mineral adsorption filter (2) wetted with water is composed of the following components by weight percentage: 65% of natural mineral adsorption filter and 35% of water;
