Embodiment 1

[0020] Prepare raw materials for embryo making, weigh 40g of 0.8mm rice husk that passed through a 40-mesh standard sieve, add 40g of pore-forming agent (0.8mm rice husk) and 135g of clay into the container and mix evenly, then add 95ml of water, and squeeze repeatedly by hand Make it mix evenly, to remove the air bubbles therein, and make it into a round cake, the diameter of the round cake is 95mm, and the height is 27mm, the prepared blank is placed in a cool place for 2 to 3 days, and the Moisture off. Passing through a 40-mesh sieve is to better control the size of the pore-forming agent, and then control the pore size. The diameter and height of the round cake are to control the contact area of ​​the pottery and thus control the filtration rate.

[0021] Step 2: During the firing process, set 200°C to preheat the muffle furnace for half an hour, put the blanks into the muffle furnace, and set three temperature ranges: 200-400°C for the pore-forming and pore-forming agen...

Embodiment 2

[0025] The difference from Example 1 lies in 135g of pottery clay, 30g of 1.2mm rice husk and 90ml of water. The diameter of the round cake is 105 mm, and the height is 23 mm. Using the above raw material ratio and method to make pottery sherds, the performance of the pottery sherds is good. comparative example

Abstract

The invention discloses an adegerming and water purifying argil filtering material, as well as a preparation method and application thereof. The materials comprises following components according to the following matching ratio: 130g-150g of clay, 30g-50g of a pore-forming agent, and 90ml-110ml of water, wherein the pore-forming agent is formed by 0.8mm rice husks or 1.2mm rice husks. according tothe adegerming and water purifying argil filtering material provided by the invention, the pore size and quantity of pottery sheets are controlled by controlling the mixing ratio and a firing method,the water purification effect is good and the use is convenient and easy.

Description

technical field [0001] The invention belongs to the technical field of water purification, and in particular relates to a sterilizing water purification clay filter material and a preparation method and application thereof. Background technique [0002] The silver-coated water purification clay pot technology solves the problem of family drinking water safety and reduces the incidence of diseases caused by poor drinking water quality. It is a low-cost terminal drinking water safety guarantee technology. This technology has been widely used in various underdeveloped and water-scarce regions around the world, and has achieved huge health and social benefits. At the heart of the technology are porous filter clay pots coated with colloidal silver. Drinking water seeps out of the clay pot by gravity, most of the impurities are filtered out, and pathogenic microorganisms are inactivated by the disinfection of the silver coating during the percolation process. This trace amount of...
