Patent CN1336349A discloses a kind of ceramic water-permeable brick and its production method, major ingredient are：Useless Wall or floor tile grain 70-
90%, feldspar powder 8-20%, cellulose 1-5%, sawdust 1-5% and appropriate amount of water.The production method of ceramic water-permeable brick is：(1) match
Material：Useless floor brick material is pulverized and sieved into 4-60 mesh, sawdust is sieved 20-60 mesh, and 10 times of water weight of cellulose are impregnated, and obtains viscosity 400-
600 degree, feldspar powder pulverizes and sieves 200-250 mesh；Useless Wall or floor tile grain, feldspar powder, cellulose, sawdust is added by formula, adds
Suitable water stirs evenly；(2) base：It is squeezed into base by predetermined size, that is, is formed, carries out 100-130 DEG C of drying, 50- later
After 70 minutes obtain 0.5% or less aqueous adobe, after calcined 100-140 minutes under the conditions of 1100-1300 DEG C.
In patent CN1336349A, it is to be added in aggregate to generate viscosity using cellulose bubble liquid, is molding viscosity
Material, the effect of the feldspar powder of addition are to generate melting in high-temperature calcination and ceramic tile particle is bonded together generation intensity, are added
The effect for entering sawdust is the water penetration for generating communication type channel when generating gap and burning and gas-exhausting after sawdust burns and improving product.
But this method has some disadvantages：The viscosity of the cellulosic pulp obtained with infusion method is difficult to control, and causes to expect in production
Viscosity is unstable, and the thickness deviation of product is larger when leading to pressing fabric.Meanwhile sawdust and solid fuel, it is being rapidly fired to
When the gas that generates of moment easily lead to adobe burst apart in exhaust, cause waste product.The method is only suitable for the push plate being burnt at a slow speed
Kiln or tunnel oven, and it is burnt into energy consumption height, product quality is difficult to control.
Patent CN1232738A discloses a kind of manufacturing method of water-permeable brick, and ceramic aggregate is broken, sieve, adhesive is nothing
Two kinds of machine clay A, B, aggregate press 4-7 mesh aggregate 85-94% using Unglazed ceramic matter brick red brick, and adhesive is viscous for low temperature high viscosity
Soil, mixing mixing, compression moulding, pressure 150-250kgf/cm2, and various color bricks are made using primary or secondary material distributing.It adopts
Main technique is：With the aggregate (accounting for 70-85% greater than 10 mesh) for being greater than 4 mesh, molding adhesive is low temperature high viscosity clay,
Bonding agent low temperature itself, in 1150-1250 DEG C of high temperature firing, ceramic aggregate particle is bonded together after bonding agent melting and
Intensity is generated, not using other fluxing agents, process for calcining and firing period do not illustrate.The simple process, but producing
In, with ceramic tile particle higher temperature required for congruent melting phenomenon occurs for bonding agent itself, and the flexural strength difficulty of product is more than 7.0Mpa/
cm2, relative energy consumption is higher.
Patent CN101182185A discloses a kind of outdoor water-permeable brick and preparation method thereof, and main technique is：Using pottery
The useless brick of porcelain is broken for the particle for being greater than 0 less than 100 mesh, by 6-8 mesh<5%, 8-30 mesh are 85-90%, and being greater than 30 mesh is 5-15%
Mass mixing, add the adhesive and water of 5wt%, be made mud, be added in mold, use 90-110pa/mm2Pressure compacting
Molding, tunnel oven is burnt at 1160-1220 DEG C, and total firing period is 26-29 hours.In that patent, swelling is mainly used
Soil is adhesive, and no other fluxing agents, directly use low temperature bentonite as fluxing agent in ingredient.Because tunnel oven mode is burnt
It is long at the time, ceramic tile grain surface soften at high temperature after be added bentonite it is fluxing, can obtain higher resistance to compression flexural strength and
Compared with the product of high water-permeability, it is most apparent the disadvantage is that tunnel oven the link of kiln loading vehicle is difficult to realize automate in process of production,
A large amount of manpower and material resources are needed, and firing time is too long, energy consumption is high.The temperature difference of upper, middle and lower is difficult to control in another tunnel oven calcining kiln,

Patent CN1919564A discloses a kind of production method of environment friendly composite ceramic water-permeable brick, and this method is with can
The industrial residue of combustion things is bottom aggregate, and grain composition is：10-20 mesh 55-65% and 20-30 mesh 35-40%, mixing are added
A certain proportion of high-temperature agglomerant and organic binder C.M.C, agitated, aging, molding, roast and obtain finished product drying.Though
Right this method utilizes industrial residue, and manufacture water-permeable passage obtains higher-strength and good when using combustible being pore former and exhaust
The product of good water penetration, in process of production, it is necessary to which by dry process, and large amount of organic carbonization, burning must expire
The process that foot discharges slowly, is suitable only for the production method that firing period is more than 12 hours or more.
Patent CN103771864B disclose it is a kind of using in-situ preparation high-temperature agglomerant preparation ceramic water-permeable brick and its
Preparation method is mainly technically characterized by introducing soluble-salt in the aggregate of water-permeable brick, and bone is added in form of an aqueous solutions
In material, it is uniformly mixed more difficult to solve the problems, such as to be added in solid form, and also eliminates the problem of preparing high-temperature agglomerant,
Simplify the link of production.But soluble-salt used is metal monovalent salt and divalent salts, and additional amount is less than 5% in aqueous solution
When, when being actually added into the salt quality in aggregate than being only 0.175%, and a large amount of water soluble salts be added, the alkalinity enhancing of aqueous solution,
The viscosity that molding adhesive can largely be destroyed, causes molding blank bonding poor, and green strength is low and model easy to stick when suppressing
At surface defect.Breakage is easily caused in compacting demoulding, mobile process, and additional amount is reduced, though it can guarantee low temperature bonding agent
Viscosity, but fluxing action is decreased obviously, can only improve melting by improving firing temperature, firing temperature will to 1170 DEG C-
1230 DEG C, cause firing energy consumption higher.
Currently, the method for domestic production ceramic water-permeable brick, is broadly divided into two major classes：(1) inorganic Low binder is used.It is main
Wanting ingredient is sodium bentonite and calcium-base bentonite, and reinforcing body hypothermia feldspar, (fusing point of low temperature feldspar is wanted as high temperature fluxing agent
It asks at 1150 DEG C or less)；(2) molding adhesive is used as using polysaccharide solution (concentration 50wt%), is made with aqueous metal salt
For high temperature fluxing agent.Although the product being prepared has preferable compression strength, flexural strength and coefficient of permeability, generally it is burnt into
Temperature need to reach 1170 DEG C or more, and for firing time at 6-29 hours, the energy consumption cost of firing accounted for 30% or more product cost, and
And yield is lower (35~100mm of product thickness), largely constrains the dosage in bigger market, and its function is only saturating
Water, reduces city " tropical island effect " and fainter sound absorption function at aqueous (gap is aqueous), and when permeable, evaporation water can not
Make certain processing to water body, it cannot be to the apparent improvement result of ambient air quality.
The negative ion ceramic ceramic tile of currently available technology production, is all made of tourmaline powder or combined type tourmaline powder or combined type
Rare earth tourmaline powder (hereinafter referred to as negative ion powder).Its preparation process is two classes：
(1) unglazed tile, polished bricks part are directly added negative ion powder in formula, ingredient, mud are made by ball milling
0.2~2.5mm powder particles are made by spray drying in slurry, mud, low by compacting, drying, high temperature firing acquisition water absorption rate
In 0.5% floor tile.Due to tourmaline powder sheet as black, short, bristly hair or beard is red or brown based on, be added in ceramic batch, firing
The aesthetics that carcass can be seriously affected after product, so additional amount is restricted.Separately because unglazed floor tiles, polished bricks, glazed tile etc. are burnt
Cheng Houwei dense body, specific gravity are 2.6~2.8g/cm3, water absorption rate is both needed to 0.5% hereinafter, and the negative ion powder quilt that is added
It is completely encapsulated in inside the carcass of complete vitreous, it is few (by addition that surface can expose aerial anionic particle
The granule size of weight percent when negative ion powder can calculate), and the liquid that ceramic tile is formed in high-temperature sintering process
It meets and immerses inside negative ion powder crystal structure, and physical-chemical reaction and variation have occurred therewith, destroy to a certain extent
The unidirectional polar axis of negative ion powder, can reduce the ability of negative ion powder launching electronics, also just reduce and to generate negative oxygen ion
Ability.Other direction, because negative ion powder is completely wrapped in inside the ceramic tile carcass of vitreous, the water absorption rate of ceramic tile is 0.5%
(it is considered that not absorbing water substantially) below has also just broken off the approach that negative ion powder directly contacts water body and air, in very great Cheng
Approach and ability that negative ion powder generates the negative oxygen ion of higher concentration are limited on degree, belong to closed transmitting anion.
(2) glazed tile class：Glazed tile, which refers to, applies the glaze layer that a layer thickness is 0.3-3.0mm on floor tile surface.And it bears
Ion powder, by being manually incorporated in glaze, by ball milling, is sieved, is made containing anion during preparing glaze slip
The glaze slip of powder.In process of production, glaze slip is allowed to be attached to ceramic adobe surface with the mode for getting rid of glaze or leaching glaze, glaze spraying, through overdrying
After dry, after 1180-1250 DEG C of high temperature firing melts, the complete vitreous of glaze paint forms compact structure, water absorption rate is less than 0.05%
Complete vitreous glazed layer, final negative ion powder is completely wrapped in inside glaze layer, and glazed layer is melted in high temperature sintering
It needs to be completely formed the full liquid phase compared with low viscosity in the process, stronger physical-chemical reaction has occurred in liquid phase and negative ion powder, right
The erosion of negative ion powder is bigger, is easier to weaken the ability of negative ion powder launching electronics.Likewise, negative ion powder is sealed completely
Closure is rolled in silicate glass body, can not directly contact wetting and air, the concentration of the negative oxygen ion of generation all can only compared with
Low level, can only be in 1300/cm3Within.

Converted starch is carbonized, and partial oxidation combustion, and CO is discharged2, for negative ion powder open connection provide gap and
Channel.
C：From 450-700 DEG C of section, required time 25-40 minutes, the aggregate of product had the thermal expansion of 0.1-0.3%, but
Voidage inside product is 20-40%, will not influence the integrality of product, and since 630 DEG C, lithium carbonate particle starts
Fusing, and gradually generate liquid phase.As the temperature rises with the continuity of time, Li2CO3The liquid phase that melt generates can penetrate into week
Side, in conjunction with albite particle, while the anion particle that part is wrapped up can reveal.
D：900-1030 DEG C of section, required time 35-45 minutes.Li2CO3The liquid phase and albite particle that melt generates are sent out
Raw congruent melting generates more liquid phases, and as temperature increases, the time increases, liquid phase can spread, be immersed in ceramic tile aggregate surface, open
Begin that congruent melting occurs with aggregate surface, while the negative ion powder wrapped up can be revealed further.
E：1030-1050 DEG C of section, required time 40-60 minutes.Surface softens ceramic tile aggregate at high temperature, and produces before
Eutectic reaction occurs for raw liquid phase, and liquid phase part penetrates into aggregate micro-crack, interpenetrates, and forms the wire type of local point type
Melting is coupled.(particles of aggregates is irregular polyhedrons, is substantially point contact between bulky grain.)
It is fired by high temperature, Li2CO3Liquid phase, and the adhesive attachment for passing through liquid phase with aggregate are formed completely with albite micro mist
To together, after rapid cooling, liquid phase solidifies the contraction for becoming solid-state again, and having 1-2% again.At this time at high temperature by liquid phase
Closed channel can become the channel of aperture again, and a part that anionic particle is closed package can be exposed (negative again
The melting temperature of ion is greater than 1310 DEG C).
Cooling procedure control is as follows：
DEG C A.1050~710 DEG C：It is quickly cooled down：It is directly sent into normal temperature air with blower, is quickly cooled down after heat exchange, institute
Take time is 3~10 minutes.
B. 20-40 minutes required from 710-450 DEG C.Slowly cool to 450 DEG C from 710 DEG C, because aggregate can generate it is biggish
It shrinks, it is necessary to control the rate of cooling, otherwise product is also easy to produce more micro-crack, directly cracks when serious, while to ensure
Product surface and the center temperature difference are unable to 50 DEG C of size.
C. 10-15 minutes required from 450-100 DEG C.It can be quickly cooled down, roller tables means of transportation Temperature fall is used after kiln discharge
To after 60 DEG C or less, pick, packaging.
