Description
One, technical field
The present invention relates to purple sand pug processing and fabricating field, particularly relate to a kind of boccaro purple mud with natural potter's clay as raw material
Processing and fabricating.
Two, background technology
Zisha earthenware, is called for short boccaro, is a class ceramic product with Chinese tradition characteristic, especially writes the most with yixing purple sand
Name.Boccaro integrates practicality, functional, ornamental, artistry and collection, is loved by the people.In recent years, along with tea
The development of culture, the continuous expansion that boccaro uses, and the continuous lifting of boccaro collection, purple-clay product especially dark-red enameled pottery
Increasingly paid close attention to by common people.
Boccaro is fired by purple sand pug and is formed, and purple sand pug is then processed by boccaro ore deposit.The generation of yixing purple sand and
Development basic reason is to have advantageous boccaro mineral resources condition: at the Huanglong Mountain etc. in Ding Shu town, boccaro concentration of production district
Ground, abounds with the boccaro raw mineral materials that processing performance is the most excellent.Locals is by all boccaros originating from Ding Shu town, Yixing Huanglong Mountain
Ore deposit is referred to as " this mountain " mineral aggregate.According to yixing purple sand pug and the purple-clay product feature fired thereof, yixing purple sand pug can be divided into purple
4 types such as mud, green mud, red soil and group's mud, they purple-clay product fired is purple mud boccaro, green mud boccaro, red soil respectively
Boccaro and group's mud boccaro, be referred to as boccaro.
(1) purple mud: because raw ore is aubergine, the purple-clay product fired is royal purple and gains the name.Purple mud iron-holder between
Between green mud and red soil, plasticity is good, and moulded pottery not yet put in a kiln to bake intensity is high, and it is little to burn till contraction, has excellent processing performance, is that yixing purple sand makes
The purple sand pug that consumption is maximum.Purple mud raw ore belongs to argillaceous siltstoue, massive structure, and principal item has that kerve is blue or green, sky blue mud and clear
The kinds such as cement.
(2) green mud: because raw ore iron-holder is relatively low, and based on ferrous iron, just the raw ore of exploitation is often in the depth not
The green of one and gain the name, because the purple-clay product fired is in having ecru or the bluish yellow color of sand sense, also known as Pericarpium Pyri mud.Green mud is former
Ore deposit belongs to silty, massive structure, typically originates from purple interburden layer, therefore has again the title of " mud in mud ", with this mountain green mud
For famous.
(3) red soil: because raw ore iron-holder is of a relatively high, the purple-clay product fired often take on a red color or kermesinus and gain the name.
Red soil has boccaro red soil and two kinds of Zhu's mud.Boccaro red soil is argillaceous siltstoue, and every processing performance is identical with common purple mud,
Raw ore mainly takes on a red color or yellow, massive structure, the most only originates in Ding Shu town, Yixing Huanglong Mountain, has big red soil (Radix Campylotropis Hirtella (Herba Myrsines Africanae)), red
The segmentation kind such as Pi Long, descending grade red soil.Zhu's mud is clayey mud stone, raw ore generally in yellow, massive structure, homogeneous carefully
Greasy, easily to twist into pieces, main Chan Zhao Zhuan Sha mountain and Hong Wei Fragrance Hill one carry, and plasticity is good, can make the thinnest extremely exquisite moulding,
But it is very big to be dried and burn till contraction, and firing temperature is on the low side, typically can only make less works.Because iron-holder is different, after burning till
Main in Vermilion, the color such as crabapple red, Cinnabaris is purple.
(4) group's mud: non-single variety mineral aggregate, but two kinds and two or more mineral aggregate symbiosis form.Group's mud is usually purple mud
With green mud symbiosis product, it is partially green mud and red soil symbiosis, seldom sees purple mud and red soil symbiosis.Yixing dialect " is rolled into a ball ", " satin "
Unisonance, and major part group cement mineral material burn till after often in multiple yellow satin tone, therefore locality, Yixing custom claims " satin mud ".Group mud because of
Symbiosis mineral aggregate kind is different with ratio and presents than more rich color.
It addition, Yixing also produce there is the tender mud ore deposit of plasticization and there is red, the orpiment of stone etc. of toning effect natural auxiliary
Helping raw mineral materials, make yixing purple sand ore deposit kind and color more diversified, this produces the origin of boccaro " five color soil " in Yixing just,
Yixing purple sand goods especially dark-red enameled pottery colourful basic reason place the most just.But, along with yixing purple sand mineral provide
Source long-term scale exploitation and red stoneware product demand constantly increase, and especially local government's taboo adopts restriction, adds for purple sand pug
The yixing purple sand ore deposit that work makes is the shortest, and the survival and development of boccaro industry are faced with huge challenge.
Making us extremely worrying, up to now, the open report of China's purple sand pug processing and fabricating technological achievement is less,
The groundwork of forefathers is as follows:
CN 1035535612A discloses the preparation method of a kind of black purple sand pug, it is characterized in that using silicon dioxide percentage
Content 30%～40%, aluminium dioxide (inventor's note: do not have " aluminium dioxide ", it may be that " aluminium oxide " or " aluminium sesquioxide ")
Percentage composition 10%～15%, ferrous oxide (inventor's note: do not have " ferrous oxide ", it may be that " ferrum oxide " or " three oxidations two
Ferrum ") Purple Shale of percentage composition 30%～40% is raw material, and air slaking, ripening, crush and screen, dispensing be pressed into bar
Etc. technique, prepare black purple sand pug.
CN 104129974A discloses a kind of steel gray section of purple clay and method for cooking thereof, it is characterized in that using Yixing
Several boccaro ore deposits be raw material, by optimizing pug group full formula, make the steel gray section of purple clay of a kind of " lost ", its pug is joined
Fang Shi: purple mud 20%～40%, Semen Sesami section mud 20%～40%, blue sky mud 5%～30%.
CN 104387018A discloses a kind of freehand brushwork in traditional Chinese painting strand tire purple clay manufacture method, it is characterized in that using Yixing
Several boccaro ore deposits be raw material, and by carrying out formulated by different proportion, make purple-clay product and there is Chinese freehand brushwork in traditional Chinese painting
The purple sand pug of picture effect.
Potter's clay is the raw material producing the various pots and pans pottery such as wine jar, pickle jar.China's potter's clay mineral resources enrich, point
Cloth also ratio is wide.If can use resourceful potter's clay is raw material, the novel purple sand pug of processing and fabricating, to China's boccaro industry
Sustainable development significant.But, understand from described above and literature search result, up to now, also less than with
Natural potter's clay is raw material, the technological achievement report of processing and fabricating boccaro purple mud.
Purple mud is current yixing purple sand usage amount purple sand pug maximum, the most of paramount importance.It is an object of the invention to, research
A kind of compare the most natural potter's clay as raw material with China's distribution, without any industrial chemicals and artificial color, processing novel
Boccaro purple mud, and according to the ceramic process performance of this boccaro purple mud and feature, fire purple mud purple-clay product.
Three, summary of the invention
Compared with purple sand pug, potter's clay has that plasticity is good, moulded pottery not yet put in a kiln to bake intensity relatively advantages of higher, but its prominent shortcoming is to burn
Become to shrink greatly, be easily deformed, thus be not suitable for use in purple sand pug；Simultaneously as the composition structure of potter's clay exists with boccaro ore deposit
Different, its method for cooking also has the feature of oneself.Therefore, how to overcome the defect of potter's clay, and optimize according to potter's clay feature
Can method for cooking, become potter's clay and be used as the key of purple sand pug.To this end, present invention employs following technical scheme.
3.1 test specimens and calcining system
Test specimen uses natural potter's clay ore deposit, and raw ore is aubergine, and earthy-lumps structure, chemical composition is w (SiO2)
50%～70%, w (Al2O3) 20%～30%, w (Fe2O3) 5%～11%, w (K2O) 1%～4%, w (CaO) < 1%.
By broken after the natural drying of potter's clay ore deposit, then according to the granule size of EXPERIMENTAL DESIGN, material is the most all passed through
The standard screen of corresponding granularity, respectively obtaining granule size is-20 mesh ,-40 mesh ,-60 mesh ,-80 mesh, the granular material of-100 mesh.
Magnetic plant is used to remove the mechanical ferrum in material of different grain size and iron ores particle respectively.
Screening materials carrying is processed into the mud cake that diameter is about 50mm, makes pottery for loss on ignition, shrinkage factor, water absorption rate and color etc.
The detection of porcelain processing performance.Then by mud cake sample natural drying, or oven drying is used (to dry temperature 80 DEG C～105 DEG C, do
The 24 hours dry time).
Firing test temperature scope is 1050 DEG C～1250 DEG C, and as a example by 1175 DEG C, calcining system is following (Fig. 1):

The heating-up time of (4) 600 DEG C～1175 DEG C is 1 hour, and heating rate is 10 DEG C/min；
(5) 1175 DEG C of constant temperature 1 hour, to sample color uniformly after, naturally cool to room temperature.
3.2 boccaro purple mud processing methods
The potter's clay pug of tradition pottery uses Whote-wet method processing, it may be assumed that potter's clay wet grinding wet screening filter pressing pugging is old
Rotten.The distinguishing feature of the method processing potter's clay pug is that pug granularity is very thin, and generally less than 200 mesh, its prominent shortcoming is pottery
Goods lack the internal features such as external appearance characteristic and crumb structure such as boccaro distinctive sand sense, and burn till contraction greatly, are easily deformed,
It is difficult to make the exquisite goods such as boccaro side's device and dark-red enameled pottery, the making various pots and pans pottery such as wine jar, pickle jar can only be produced
Product.
Potter's clay pug that Tables 1 and 2 is the most traditionally processed and burning till after adding different percentage composition grog thereof
Shrinkage factor, it will thus be seen that in the case of being not added with any grog, the potter's clay pug percent of firing shrinkage right and wrong of traditional method processing
Chang great, its linear shrinkage ratio and cubical contraction (Tables 1 and 2 meansigma methods) respectively reach 7.90% and 23.11%, this potter's clay just
The basic reason place that pug is easily deformed.
Grog is the product processed through high-temperature calcination, will not produce contraction at a certain temperature again, therefore adds grog and becomes
The basic skills of ceramic deformation is reduced for forefathers.As can be seen from Table 1 and Table 2, by adding Different Weight percentage composition grog,
Its percent of firing shrinkage makes moderate progress, but effect inconspicuous, even grog adds weight percentage and reaches 40%, it is also difficult to full
Foot boccaro requirement.And consequent negative interaction is, owing to grog is almost without plastic non-plastic raw material, along with grog adds
Adding weight to increase, pug plasticity substantially reduces, and is unfavorable for molding and the processing of pottery.It is pointed out that contrast table 1 and table
2 it appeared that: for burning till the improvement effect of contraction, add the bigger grog (table 2) of granularity and be better than the grog (table that granularity is less
1)。
Potter's clay pug and interpolation Different Weight percentage composition grog (-200 mesh, 75 μm) thereof of the processing of table 1 traditional method exist
The percent of firing shrinkage (%) of 1200 DEG C
Note: grog system use potter's clay pug of the same race, through 1250 DEG C of calcinings, natural cooling, crush form
Potter's clay pug and interpolation Different Weight percentage composition grog (-40 mesh, 450 μm) thereof of the processing of table 2 traditional method exist
The percent of firing shrinkage (%) of 1200 DEG C
Note: grog system use potter's clay pug of the same race, through 1250 DEG C of calcinings, natural cooling, crush form
To this end, the potter's clay pug of the present invention uses dry method+wet method processing, it may be assumed that potter's clay is dried broken dry screen profit
Wet stirring pugging is old.Table 3 is in the case of firing condition is identical with Tables 1 and 2 with Fig. 2, uses this
The percent of firing shrinkage of the different grain size potter's clay pug of bright method processing, it will thus be seen that with the potter's clay pug phase of traditional method processing
Ratio, the pug percent of firing shrinkage of the inventive method processing significantly reduces；Along with the reduction of granularity, burn till contraction in being gradually increased
Gesture, even if be granularity be-100 mesh, its burn till shrink also comply with purple sand pug fire requirement.Therefore, the present invention adds respectively
-20 mesh of work ,-40 mesh ,-60 mesh ,-80 mesh, the pug percent of firing shrinkage of-100 mesh all meet the making requirement of purple sand pug.
Result of the test shows further, the purple sand pug of the inventive method processing, and along with granularity increases, contraction distortion becomes
Few, burning till stability increases, and the sand sense of purple-clay product outward appearance strengthens, but plasticity has declined.Otherwise, along with granularity
Reducing, contraction distortion becomes big, burns till stability and reduces, the more gentle exquisiteness of purple-clay product outward appearance.So, it should according to boccaro system
The size of product and needs, rationally select the size of broken processing granularity, it may be assumed that if making the boccaro that type is relatively big or deformation is the least
Goods, can be selected for-20 mesh～-40 mesh；If making the purple-clay product that type is less, can be selected for-60 mesh～-100 mesh.
The different grain size potter's clay pug of table 3 the inventive method processing is at the percent of firing shrinkage (%) of 1200 DEG C
Note: constant temperature time 1h
The firing temperature of 3.3 boccaro purple mud
The composition structures shape ceramic process performance of Ceramic Material.And in the case of Ceramic Material is certain, ceramic process
Performance is then decided by burning process method.The ceramic process performances such as loss on ignition, shrinkage factor, water absorption rate and color determine that purple sand ceramics
The important technology index of device quality, can be that the optimization of the firing temperature of potter's clay boccaro purple mud provides scientific basis.Table 4 is the present invention
Potter's clay boccaro purple mud (-60 mesh) of processing is in the testing result (%) of 1050 DEG C～1250 DEG C different temperatures firing samples, permissible
Find out:
Table 4 potter's clay boccaro purple mud different temperatures burns till the ceramic process performance test results (%) of sample
Note: pug granularity-60 mesh, constant temperature time 1h
(1) loss on ignition: potter's clay boccaro purple mud sample changes little the loss on ignition of 1050 DEG C～1250 DEG C, is up to
6.53%, minimum 6.32%, average out to 6.47%, similar to yixing purple sand pug, meet zisha earthenware quality and want with firing
Ask.
(2) shrinkage factor: potter's clay boccaro purple mud sample is respectively 4.17% He from linear shrinkage and the volume contraction of 1050 DEG C
10.99%, reach maximum to shrinkage factor when 1175 DEG C, respectively 7.13% and 19.98%, then start to expand, to 1250 DEG C
Sample drastically expands, and now linear shrinkage and volume contraction are respectively 3.78% and 3.37%.As can be seen from Figure 3, sample is at 1050 DEG C
～the linear shrinkage ratio of 1200 DEG C and cubical contraction all increase along with the rising of temperature, 1200 DEG C～1250 DEG C of base substrates start by
Gradually expanding, in terms of entirety, the shrinkage factor curve of sample is parabola, and parabolical summit is at about 1185 DEG C.Therefore, can will burn
Temperature range is become to be defined as 1150 DEG C～1200 DEG C.
(3) water absorption rate: potter's clay boccaro purple mud sample drops along with the rising of temperature at the water absorption rate of 1050 DEG C～1250 DEG C
Low, i.e. 8.65% from 1050 DEG C time, 0.97% when dropping to 1250 DEG C.Having certain water absorption rate is that boccaro is different from porcelain
Key character.Therefore, firing range can be defined as 1150 DEG C～1200 DEG C.
The color of 3.4 purple mud boccaros controls
Purple sand pug, due to the difference of iron-holder, can present various color after burning till, as purple mud burns till rear one
As in grey violet～darkviolet, green mud is typically ecru after burning till, red soil burn till after in brick-red or vermilion or kermesinus.And
And same pug burns till in different temperature, the color of boccaro also can be different.
Fig. 4 is the color that potter's clay boccaro purple mud different temperatures burns till sample.In order to more intuitive data embody boccaro
Burning till the change of rear color, use the full-automatic whiteness instrument of WSD-III that purple mud boccaro has been carried out the test of colorimetric parameter, result is shown in
Table 5.
As seen from Figure 4, along with the rising of temperature, potter's clay purple mud boccaro color from light to dark, present light violet magenta～
Aubergine～darkviolet～the change of taupe.The chromatic value burning till base substrate from different temperatures can be seen that (table 5), is burning till temperature
Before degree, the brightness value L* and red scale value a* of base substrate reduce with the rising of temperature, and after burning, base substrate is owing to starting vitreous
Reflective degree is strengthened, and brightness value raises.Therefore, can as required, under 1200 DEG C of temperature conditionss, it is thus achieved that grey violet～darkviolet
Purple mud purple-clay product.
