Inventive principle
1, lithotome has texture changeable, the strong characteristic of penetrating sense; Glomerocryst powder content in the glomerocryst micro mist polished brick in porcelain character generally is controlled at 30%～40% of lining; This has influenced the fidelity of product surface to stone material to a certain extent; For obtaining the lithotome decorative effect, the present invention brings up to 90% of lining with the content of glomerocryst micro mist.
2, the stamp half tone is adjusted, adopted ultra-fine printing technique, make fine and smooth, the levels are rich of the pattern texture that prints off.
3, to introducing high-load low temperature material in the prescription, formulate rational calcining system.
4, the cloth system of press is transformed, increased the equipment of lines material and particle material.
Main inventive point
1, adopts high-content glomerocryst micro mist layer proportioning, make the content of glomerocryst micro mist reach 90% of lining.
2, adopt ultra-fine printing technique, make fine and smooth, the levels are rich of the pattern texture that prints off.In passing production, in order to prevent the stamp-pad ink block, adopt thicker half tone more, the lines that print off are thick excessively, and decorative effect is barely satisfactory.In triturating, half tone is adjusted, used instead fine-structure mesh version stamp, in stamp, add lubricant, efficiently solve the block problem.
3, through to the scrap build of press cloth system, increased lines material and particle material equipment, made the lines textured pattern abundanter.
The key point of embodiment of the present invention
1, adjustment blank proportioning is formulated reasonable technological, improves green strength, reduces defective.
We find in triturating, and blank strength descends along with the increase of glomerocryst micro mist material add-on, and promptly the two is inverse relation; At the press shaping stage, the interlayer phenomenon also appears in base substrate.
We have carried out following research and experiment to these problems:
(1) (the theoretical chemistry general formula is Al in the blank proportioning, suitably to increase smectite type mineral
2O
34SiO
2NH
2O) improve blank strength.
Smectite belongs to oblique system, and such mineral are main constituents of useful raw clay such as wilkinite, fuller's earth.Wherein wilkinite then is a ceramic industry fluidizer commonly used, and its characteristic is that particle is superfine, cohesive force is strong especially.When mixing with water, water molecules can be invaded between the structural unit layer, thereby gives strong especially swelling character---volumetric expansion, and is gel state.When in base substrate, mixing proper amount of bentone, can significantly increase the plasticity-and the dry tenacity of blank.
Clay content and dry body strength graph of a relation
Can know that by figure dry body strength N increases along with the percentage composition increase of clay content Wt and reaches a peak, but when clay content continued to increase, dry body strength N can not improve not only again, can reduce on the contrary.
(2) in blank, introduce the intensity that toughener improves base substrate
The base substrate toughener is a kind of organic polymer material, and molecular chain is longer, during with the blank ball milling; Be dispersed in the mud, can improve the bonding force between pulp particle, thereby reach the purpose that strengthens blank strength; But add-on too much can make the mud retrogradation, mobile variation.
Through above measure, green strength is brought up to 1.4～1.6MPa by 1.1 original～1.2MPa.
(3) formulate reasonable technological and solve the interlayer problem
1. confirm the powder moisture content based on the compacting Capability index
In the base substrate proportioning, introduce high-load glomerocryst micro mist material,, very easily form the excessive existence of fine powder in the powder if the powder water ratio is crossed when low, the one, reduced the tap density of powder, powder unit weight is reduced, gas vol increases in the powder.Therefore, cause air scavenge not cause interlayer only easily; The 2nd, after powder received compacting for the first time in the die cavity, fine powder drifted about to four limits, stops up the exhaust-duct, makes air scavenge freely not produce interlayer.
When the powder water ratio increased gradually, because the lubrication of water, the degree of compactness of base substrate also increased during press forming.But when water ratio surpassed to a certain degree, the degree of compactness of base substrate reduced on the contrary, and a large amount of interlayers occur.This is that the powder gap reduces greatly because during press punching press for the first time, and ventilation property reduces, and remain a large amount of residual gas in the base substrate this moment, and when carrying out second time punching press again, the interior gas of base substrate is extruded into a certain position, promptly produces interlayer.
This shows, solve the base substrate interlayer defect, will confirm suitable powder water ratio, we have tentatively confirmed the powder water ratio according to the measuring and calculating of base substrate compacting Capability index:
Ps＝S/N
In the formula: Ps---the compacting Capability index
S---dry body rupture stress (MPa)
N---wet base rupture stress (MPa)
Measuring and calculating shows, when the compacting Capability index 2～4 the time, base substrate is difficult for taking place interlayer, if when adopting elevated pressures to be shaped, can suitably reduce powder moisture.In conjunction with the practical condition of our factory, confirm that finally the water ratio of glomerocryst micro mist material is 5.6%～6.3%.
2. guarantee that powder has the sufficient old time
Through the powder that spraying drying makes, its moisture is uneven, and this just needs an old process especially.In old process, powder is in the environment of approximate sealing, and temperature of charge is higher than envrionment temperature, and capillary action is obvious, and the moisture penetration diffusion is good, is tending towards even.In addition, powder also can produce the bacterial reproduction effect in the old process, and humic-acid-type substances increases, and is accompanied by redox reaction.So powder is through after certain hour old, moisture is even, and mobile, associativity improves, thereby has improved the powder forming property, reduces interlayer and other defective.
On basis to the various material performances and the degree analyzing that influences each other; We adopt orthogonal experiment that old time of powder, powder water uniformity, powder flowability, forming property are analyzed and researched as the correlative factor that influences the base substrate interlayer; And the bonding apparatus operation conditions, the old time of confirming powder is to be advisable in 24～32 hours.
2, adjustment stamp half tone, the diffusion of control stamp oil fineness and pattern
For the product surface pattern reaches the fine and smooth effect of stone texture, we adjust half tone, use fine-structure mesh version stamp instead, but often occur that silk screen gets clogged or decorative pattern obscurity boundary, problem such as unintelligible.This is taked following measure:
(1) fineness of control stamp oil.Test shows that with half upper limit as the fineness particle size of silk screen mesh opening size size, just few phenomenon that half tone occurs blocking if in stamp, add lubricant again, just can more effectively solve the block problem when stamp.
(2) spraying concentration at the brick face behind the stamp is the non-proliferation water of 20%～30% (weight ratio), efficiently solves the problem of decorative pattern infiltration diffusion.
3,, formulate rational sintering curve according to the proportioning characteristics
Because Al in the smectite
2O
3Content lower, adsorbed other positively charged ion again, so firing temperature is lower, its dehydration temperaturre is 600 ℃～700 ℃, and the moisture velocity of discharge relaxes.To this characteristic, we adjust sintering curve, and preheating zone temperature has in earlier stage been improved 40 ℃～50 ℃; The temperature in later stage has reduced by 60 ℃～70 ℃.
Burn till and adopt length * wide=230m * 2.6m roller kiln, firing period 80 minutes.
The sintering curve of carrying out is following:
4, press cloth system scrap build makes the lines textured pattern abundanter.
In triturating, grid, particle distribution device and batch mixing belt speed, drum rotational speed that we find former cloth system etc. all can not satisfy the design requirements of this project product.Therefore, aforesaid device is transformed.
Parameter comparison before and after transforming:
| Classification | Before the transformation | After the transformation |
| Grid | / | Increase imitative bag reason device |
| Batch mixing belt speed (HZ) | 40 | 15 |
| Drum rotational speed (HZ) | 40 | 15 |
