Abstract
The invention discloses an ion exchange filter element which is mainly prepared from the following raw materials in percentage by weight: 10-35% of attapulgite of 100-300 meshes, 35-60% of vermiculite of 200-400 meshes and 10-35% of a fiber adhesive of 100-300 meshes. With the adoption of the technical scheme, the ion exchange filter element disclosed by the invention is prepared by taking the attapulgite, vermiculite and fiber adhesive as raw materials; the attapulgite has an absorption effect and an ion exchange capacity and is capable of removing colors, deodorizing, removing odor and the like; due to a relatively high layer charge number, the vermiculite has a relatively high cation exchange capacity and a relatively high cation exchange adsorption capacity and is convenient for mineral salt adsorption; and the fiber adhesive contributes to molding and prevents a finished product from deforming and shrinking in the using process and the like. Moreover, the ion exchange filter element is fibriform after processing, and a micro-porous structure of the filter element is well kept.
Description
Technical field
The invention belongs to filtering material technical field, it is related to a kind of ion exchange filter core.
Background technology
In water treatment system, water is pre-processed frequently with activated carbon, the common Water treatment filter element kind of in the market
It is more single, usually active carbon filter core, polypropylene melt blown filter or ceramic element etc..Although traditional active carbon filter core tool
There is good suction-operated, chlorine residue, peculiar smell and the color that can effectively go in water removal etc., polypropylene melt blown filter and ceramic element are then
Filter effect to magazines such as silt or suspensions is preferable.Above-mentioned common filtering element for treating water is to heavy-metal ion removal and agriculture
The abilities such as medicine are very limited.Additionally, the mechanical interception ability of traditional Water treatment filter element is poor etc..
Vermiculite is a kind of natural, inorganic, nontoxic mineral matter, with ion-exchange capacity, can be used as adsorbent.
Attapulgite refers to a kind of clay mineral with attapulgite as key component, and attapulgite is also known as palygorskite or slope
Thread thin white silk used in ancient China stone, is a kind of clay mineral of zeopan containing Shuifu County for having chain layer structure.Because attapulgite has unique crystalline substance
Body structure, is allowed to cation interchangeability, water imbibition, adsorption bleaching, big specific surface area and colloid index and expansion
Physical and chemical performance and the processing performances such as appearance.
Therefore, attapulgite and vermiculite above have great application prospect in the application of water process.
The processing method of traditional filter core is generally using extrusion forming or the processing method of sinter molding.In extrusion forming
In processing, curable type generally is aided in added with glue, this glue easily blocks filter core micropore, can destroy 70% micropore, and filter material is to water
Resistance become big.Water-flowing amount diminishes, and hydrophily is deteriorated, and causes the filter core after extrusion forming is processed, and its water-flowing amount is low, filtering
Efficiency is low.In sinter molding processing, curable type is generally aided in using binding agent, after through high-temperature activation, block filter core micropore, it is right
The resistance of water becomes big.Water-flowing amount diminishes, and hydrophily is deteriorated, and causes that the filter efficiency of filter core is low, and effect is poor.
Therefore, it is necessary to studying one kind can largely keep filter core micropore, the processing method of the preferable filter core of hydrophily.
The content of the invention
In view of this, it is commutative to go to eliminate the unusual smell, go in water removal it is an object of the invention to provide a kind of ion exchange filter core
The ion of dissolving, gluey ion, heavy metal and its compound etc..
In order to reach above-mentioned purpose, the technical scheme is that：
A kind of ion exchange filter core, is mainly prepared from by the raw material of following percentage by weight：
The attapulgite 10%-25% of 100 mesh~300 mesh；
200 mesh~400 mesh vermiculites 45%~75%；
The fiber binder 10%~35% of 100 mesh~300 mesh.
Mainly it is prepared from by the raw material of following percentage by weight：
Attapulgite 15%-20% described in 100 mesh~300 purposes；
Vermiculite 55%~63% described in 200 mesh~400 purposes；
Fiber binder 20%~28% described in 100 mesh~300 purposes.
Mainly it is prepared from by the raw material of following percentage by weight：
The attapulgite 20%-25% of 100 mesh~300 mesh；
200 mesh~400 mesh vermiculites 60%~70%；
The fiber binder 10%~15% of 100 mesh~300 mesh.
The fiber binder name of an article is BiPUL 50TWG, and spinning Co., Ltd. by Japanese Japan provides.
A kind of preparation method of ion exchange filter core, comprises the following steps：
(1) prepare the attapulgite of 100 mesh~300 mesh, the fiber of mesh~300 mesh of vermiculite 100 of 200 mesh~400 mesh to glue
Mixture；
(2) stir：Raw material input temporary storage tank is carried out in mixing and stirring, temporary storage tank added with pure water, it is described
The amount of pure water is 15-22 with raw material otal investment ratio：1, the original slurry material of sticky shape is formed after stirring；
(3) it is molded：By step 2) obtained by original slurry material wet type shaped device be delivered to by pipe-line transportation system enter successively
Row suction and integer, and then be molded, obtain first product；Or, by step 2) obtained by original slurry material by pipe-line transportation system convey
Forming processes are carried out to moulding machine, first product is obtained；
(4) dry：By step 2) obtained by first product be sent to baking oven, at a temperature of 100~150 DEG C, dry 6~10 small
When, obtain finished product.
The wet type shaped device uses suction feeder, during the suction, according to suction amount and vacuum
Control the time of suction.
In the whipping process, the amount of the pure water is 18~19 with the raw material otal investment ratio：1；Institute
State in baking step, the first product dries 7.5~8.5h in 120~125 DEG C of the baking oven, obtains finished product.
The finished product is tubulose or sheet.
After adopting the above technical scheme, a kind of ion exchange filter core of the invention, with attapulgite, vermiculite and fiber binder
For raw material is made, attapulgite has suction-operated and ion-exchange capacity, can decolourize, deodorant to taste etc.；Vermiculite also has
There is ion-exchange capacity；Fiber binder contributes to shaping, prevents finished product from deforming shrink etc. in use.With it is traditional from
Sub-exchange resin is compared, and regenerating easily, pollution-free, exchange velocity are fast, exchange capacity is big, alternative ion exchange resin.
A kind of preparation method of ion exchange filter core of the present invention, by mixing, being molded and baking step, technique letter
It is single, the temperature that control is dried when drying so that the colloid of fiber binder can melt and not coking, still in fibre after processing
Dimension shape, it is ensured that quality of finished.Compared with traditional technology, the present invention is bonded using the preparation method of wet type shaping by fiber
The filtration core that agent is made, fiber binder is not easily blocked filter core micropore, the so filter of shaping also in threadiness in finished product filter core
Core remains filter core micropore, i.e., do not destroy micropore, not blocking microporous, can reduce the resistance being subject to during filter element filtering, and filtering is logical
Freely, and larger water-flowing amount can be formed, the service life of filter core can also be extended while with excellent hydrophilic.
