Abstract

A kind of selenium-rich Carbon rod filter element and preparation method thereof, is related to a kind of Carbon rod filter element.A kind of selenium-rich Carbon rod filter element is provided, the raw material composition of its feature by mass percentage is activated carbon 30%~58%, selenium mineral powder 20% ~ 40%, carrier powder 1%~35%, bonding agent 1%~15%, stirred after being mixed in its respective ratio, it is filled into specifically mould, both mold ends add end cap, is compacted mixing material with press, place into drying box and sinter, sintering terminates, and mould is taken out and cooled down, and finished product is made after the demoulding, selenium-rich carbon rod length is customized according to the length of mould, can avoid the secondary pollution caused by cutting selenium-rich carbon rod.The present invention can be used for water filtration, can preferably discharge the selenium element in selenium mineral powder, and present invention making materials safety is nontoxic, have the advantages that purification efficiency is high, discharging selenium element content height, the pressure loss, small, wear-resistant, service life is long.

Description

A kind of selenium-rich Carbon rod filter element and preparation method thereof

Technical field

The present invention relates to a kind of Carbon rod filter element, more particularly, to a kind of selenium-rich Carbon rod filter element and preparation method thereof..

Background technology

With China's science and technology and rapid development of economy, people is particularly good for living standard also more and more higher to the mankind Research and development in terms of health constantly strengthen, so as to carry out the research of emphasis to " selenium ", " Zhong Shi " biological selenium-enriched technology confirms selenium It is the indispensable micronutrient element of human body as iodine.Modern science is it has been proved that selenium has anti-cancer, anticancer, the preventing and treating heart The effect of more than the 400 kinds of disease such as cranial vascular disease, hepatopathy, diabetes, gynaecological disease, prostate and cataract, with anti-oxidant, clear Except interior free yl, improve immunity, many specific functions of anti-aging.Human body keeps taking in daily the selenium of 200 micrograms or so, Can effective prevention of various diseases generation.Especially children's selenium deficiency is prone to multi-infection disease, influences the brain of children Development, causes brain paralysis complication, the incidence of disease and is rising year by year.Children's selenium-supply energy strengthen immunity, helps lead discharging heavy with other Metal, allows child good appetite, intelligence be good, constitution is good.

Selenium in plant also has part from the fertilizer manually applied essentially from soil, water layer, air.Plant is main By root absorption selemium nutrition, blade, stem assist absorption selemium nutrition.The absorption of Selenium By The Plants is an active process.Selenium in Plants Content depends on plant species, the selenium content in the soil moisture of growth and using degree.The selenium of different kenels is to planting in soil The effect of thing is different.But in identical soil and environment, the different absorbability differences to selenium of species are also larger.Plant absorption Inorganic selenium or low molecular Organic Selenium, are converted into Organic Selenium, and organic selenium source of high bioavilability is provided for the mankind.Plant is Natural Organic Selenium synthesis biochemical plant.As can be seen here, plant not only accounts for critical role in the conversion of nature selenium ecological chain, and And needed by human body selenium can be directly supplemented, and ensure healthy, the meaning of reality with universal, therefore selenium-rich carbon rod produces richness Absorption of the selenium water to plant becomes apparent from, and produces the effect containing selenium-enriched plant more preferable.

The content of the invention

It is an object of the invention to, using simply selenium ore particles are placed directly within water, fail fully release for existing The defect of selenium element in selenium ore there is provided it is a kind of with the selenium-rich Carbon rod filter element for fully discharging the selenium element in selenium ore and Its preparation method.

A kind of selenium-rich Carbon rod filter element, the raw material composition of its feature by mass percentage is activated carbon 30%~58%, Selenium mineral powder 20% ~ 40%, carrier powder 1%~35%, bonding agent 1%~15%, in stirring after its respective ratio mixing Uniformly, it is filled into specifically mould, both mold ends add end cap, is compacted mixing material with press, places into drying box In with 200 DEG C -350 DEG C sinter, the time be 20 minutes to 60 minutes, sintering terminates, by mould take out cool down, after the demoulding i.e. make Into selenium-rich carbon rod finished product.

The activated carbon is at least one of coconut husk charcoal, fruit shell carbon, olive shell charcoal, bamboo charcoal, its grain fineness is 10~ 2000 mesh.

The carrier powder is polypropylene, ethylene-vinyl acetate copolymer, ultra-high polyethylene, in melmac At least one, its grain fineness is 10~2000 mesh, and the bonding agent is TPO, CMC, poly- second At least one of alkene, PVP, its grain fineness are 10~2000 mesh.

The selenium mineral powder material be with after the ore extraction containing selenium through processing crushing obtain, its grain fineness be 16~ 8000 mesh.

The mold shape is one kind in circular, square, quincunx, other abnormity, and its material uses metal, and mould is long Depending on the need for spending according to product.

The present invention is further illustrated for following examples.

Embodiment

By activated carbon: ore deposit selenium powder：Carrier powder: bonding agent=50%: 30%: 15%：5% ratio mixing, in high-speed stirring Mix and be sufficiently mixed in machine uniformly, mix uniform, with being filled into the filter core of ten cun of standard in mould, both mold ends add end cap, use pressure Mixing material is compacted by machinery, then is positioned over baking sintering 50 minutes in 280 DEG C of baking ovens, and sintering terminates, and mould is taken out into cold But, the finished product of the hollow column carbon rod of selenium-rich is made after the demoulding.
