[0013] Mix by gac: sodium selenite: binding agent=55%: 1%: 44%, fully mix in the high-speed mixer, mix evenly, pour in the mold of the filter core of standard ten inches, mold two ends add For the end cap, use a pressure machine to compact the mixed material, and then place it in an oven at 280°C to bake and sinter for 50 minutes. After the sintering is completed, take out the mold and cool it. After demolding, the finished selenium-rich hollow cylindrical filter element is made.

specific Embodiment approach 3

[0015] By gac: sodium selenite: binder=55%: 1%: mix in the ratio of 44%, fully mix homogeneously in the high-speed mixer, then it is filled in the mold of required round cake shape, and then The mold is placed in a vulcanizing machine and vulcanized at a temperature of 260° C. for 50 minutes. After the vulcanization is completed, the mold is taken out to cool, and after demoulding, the finished selenium-enriched filter sheet is made.

Abstract

The invention discloses a preparation method of a selenium-rich filter element, and relates to a carbon rod filter element. The selenium-rich filter element is characterized by being prepared from thefollowing raw materials in percentage by mass: 10-85% of activated carbon, 1-65% of selenium-containing material and 5-85% of adhesive, the raw materials are mixed according to respective corresponding proportions and then uniformly stirred, and the mixture is fed into specific equipment by feeding equipment to be treated to obtain a finished product of the selenium-rich filter element. The invention aims to provide a method for preventing heavy metal in a selenium-rich filter element from exceeding the standard in order to overcome the defect of harm caused by the fact that heavy metal in anexisting selenium-rich filter element exceeds the standard.

Description

technical field [0001] The invention relates to a carbon rod filter element, in particular to a preparation method of a selenium-enriched filter element. Background technique [0002] With the rapid development of my country's science and technology and economy, people's living standards are getting higher and higher, especially the research and development of human health has been continuously enhanced, so that the key research on "selenium", "Zhong's" biological Selenium-rich technology proves that selenium, like iodine, is an indispensable micronutrient for the human body. Modern science has proved that selenium has anti-cancer, anti-cancer, cardiovascular and cerebrovascular diseases, liver diseases, diabetes, gynecological diseases, prostate and cataracts and more than 400 kinds of diseases. Anti-aging many special functions. The human body maintains a daily intake of about 200 micrograms of selenium, which can effectively prevent the occurrence of various diseases. I...
