Abstract
The invention is a preparation method for anion ceramsite. The anion ceramsite is prepared from 60 to 84% of shale fly, 10 to 25% of clay, 5 to 10% of tourmalinite powder and 1 to 5% of sawdust through acquisition of the raw materials, mixing and treatment of the raw materials, preparation of raw balls, screening and circularization, sintering, etc. Due to addition of the anionic tourmalinite powder with high activity in the produced anion ceramsite, tens of thousands of counter electrodes can be formed, so electric decomposition effect is exerted on water in the moment when the anion ceramsite contacts with water, which enables water to become slightly alkaline. Macromolecular groups of water are changed into micromolecular groups under infrared action; and the anion ceramsite has strong dissolving capacity and osmotic force and can be used for advanced treatment and reclamation of water and the like for improvement of water quality. When people take a bath in water in which the anion ceramsite is soaked, blood flow is increased; and since the anion ceramsite has interfacial activity and substances like cholesterol in the body can be emulsified and do not deposit and accumulate on blood vessel walls, thereby preventing occurrence of diseases like arteriosclerosis.
Description
Technical field
The present invention relates to a kind of different ratio mixture utilizing many kinds of substance and prepare the side of anion haydite
Method, is directed primarily to a kind of with shale powder, tourmaline powder, clay and sawdust for raw material baking ceramsite
Method.
Background technology
At present, the patent about haydite preparation method has a lot, and primary raw material is clay, mud, stove
Slag, flyash, colliery overburden etc., and add binding agent, additive is prepared from.But clay,
The utilization of loess, not only causes arable land destruction, soil erosion etc., and obtained haydite is the closeest
Spend bigger than normal, low strength, absorption property are poor, mechanical property is poor with thermal property, and should be diligent
Can be less.
Shale is to be deposited, by clay, the rock formed through pressure and temperature, and shale is the one of clay rock,
Complicated component, in addition to clay mineral, possibly together with many detrital minerals and authigenic mineral, has laminated or thin
Platy layer is managed, and is to be formed after compaction, dehydration, recrystallization by clay material.Page
Rock is formed in the environment of hydrostatic, silt through for a long time deposition, so be frequently present in lake,
Fluvial-delta area, also has the formation of shale in continental shelf, ocean, also usually comprises in shale
Ancient times vegeto-animal fossil.The composition of shale Ore be by total amount more than 40% illite and montomorillonite
It is main, kaolinite and pureed shale that zeolite is auxiliary composition；Utilize shale powder both at home and abroad at present, middle
Being mixed into some metal ore material, the haydite produced has that body is light, intensity is big, absorption property is good
Feature, the aspect such as advanced treating resource that may be used for water, can play the effect improving water quality.
Past, tourmaline was treated as jewel mineral by people always, and the non-gem application to tourmaline is ground
Study carefully and be not realized, cause the substantial amounts of tourmaline resource that can not make gem to can not get developing, or
It is only used as grinding-material raw material, or abandons.The tourmaline being suitable as gem is after all
Minority, great majority can not become raw material for gem, so the profound level as industrial mineral should be strengthened energetically
The research of value.Tourmaline is as a kind of novel environmental protection mineral, and national departments concerned is also being closed
Note the developments of this new branch of science, and give certain support, the Xinjiang of current China, Shandong,
Yunnan, Guangxi, Jiangsu etc. save existing tourmaline raw ore, crystal (monocrystalline), micropowder, super fine raw material
Supply.In exploitation applied research, the product developed has environment-friendly type ball syringe, tap water purifying to use
Ceramic Balls, anion function fiber, tourmaline coating for internal and external wall and air-deodouring agent etc..
Tourmaline composition and structure tourmaline are a kind of to be characterized with boracic, complicated ring-type of chemical composition
The silicate mineral of structure.The general chemistry of tourmaline consists of
XY3Z6[Si6O18][BO3]3(O, OH, F)4, wherein X=Ca, K, Na；Y=Fe2+,
Mg2+, Al, Li, Fe3+, Mn2+；Z=Al, Cr3+, Fe3+；Its crystal structure is by [Si6O18] multiple
Tripartite's ring, X polyhedron, [Y-O5(OH)] triple octahedrons, six Z octahedrons and [BO3]
Plane triangle forms.
The critical function characteristic of tourmaline is pyroelectricity and piezoelectricity, produces thermoelectricity under suitable condition
Effect and piezoelectric effect.Pyroelectric effect refer to certain crystal when temperature changes, a part of band is just
The a part of electronegative phenomenon of electricity.And piezoelectric effect refers to that crystal produces under pressure and is polarized in two
There is the characteristic of electric potential difference in end surfaces.Due to the effect of both effects, when temperature and pressure becomes
During change, anion function ceramic material can make to be partially formed high voltage about, and this energy be enough to make
Air ionizes, and the neighbouring molecule that is electronically attached to of generation is allowed to be converted into negative aeroion, empty
Healthy effect is proved by gas anion by numerous institutes, and tourmaline non-secondary pollution can be anti-
Multiple use, the electric polarity of tourmaline particle affects the oxidation-reduction potential of aqueous solution, under electric field action,
Hydrone occurs electrolysis to form bioactive molecule H3O+, attract the impurity in water, dirt, it is possible to purify water
Matter.
As can be seen here, above-mentioned existing anion haydite compounds and in preparation method raw-material, aobvious
The most still there is the space continuing to expand, it would be highly desirable to improved.In order to solve the problem of above-mentioned existence, relevant
Manufacturer seeks solution the most painstakingly, but has no that applicable design is sent out the most always
Exhibition completes, and the method that is typically prepared does not has appropriate method to can solve the problem that the problems referred to above, and these are obvious
It it is the anxious problem to be solved of relevant dealer.The most how to found the compounding of a kind of new anion haydite
And preparation method, one of current important research and development problem of real genus, also become current industry and need the mesh of improvement badly
Mark.
