preparation example Construction

[0040] A preparation method of a porous glass filter element for a water purifier, comprising the following steps:

[0041] (1) After sorting out the metals and plastics in the collected recycled glass (one or more of container glass, flat glass or substrate glass), crush the recycled glass to particles with a particle size of less than 5mm to obtain cullet Granules, and then pass the broken glass particles through a 350 or 400 mesh sieve to obtain glass powder, wherein the grinding medium in the ball mill is one of agate balls, zirconia balls or corundum balls with an average diameter of 8-20mm or more, the number ratio of large balls, medium balls and small balls in the ball mill is 1:1:1, and the mass ratio of ball milling media to cullet particles is 1:1 during the ball milling process;

[0042] (2) In terms of parts by mass, take 30 to 80 parts of the glass powder obtained in step (1), mix it with 5 to 8 parts of chemically pure boric acid to obtain a glass powder boric a...

Abstract

The invention discloses a method for preparing a porous glass filter element for a water purifier. The method comprises the following steps: crushing and ball-milling the recycled glass, mixing with a certain amount of boric acid, spraying a certain amount of inorganic salt solution, drying, adding an adhesive of a certain mass, uniformly mixing, pressing, molding, and sintering, thereby obtaining an initial sample; adding the sample into water at the temperature of 100 DEG C or ultrasonic waves for cleaning, thereby obtaining porous glass with through holes. According to the porous glass filter element disclosed by the invention, the problems such as high preparation temperature, low strength, extremely large pore diameter and the like are solved, and the porous glass filter element has the advantages of excellent physical performance, high chemical stability, low preparation temperature, low cost, simple process flow and the like.

Description

technical field [0001] The invention relates to a water purifier in the technical field of water purification, in particular to a preparation method of a porous glass filter element for a water purifier. Background technique [0002] Water is a life resource, and the quality of drinking water is closely related to people's health. According to the World Health Qualification Survey, 80% of diseases and 50% of child deaths in the world are related to poor drinking water quality. In my country, about 1 / 4 of the population is drinking water that does not meet hygienic standards. Water pollution has become The most important water environment problem in our country. The main causes of secondary pollution of drinking water are: pipeline corrosion, scaling, seepage of anti-corrosion lining, microbial reproduction, residual chlorine disinfection by-products, and secondary pollution caused by the outside world. Therefore, as people gradually understand the impact of drinking water q...
