Description
Technical field
The present invention relates to the preparation methods of pottery, and in particular to the drying means of Nixing pottery.
Background technique
Qiezhou Nixing pottery, scientific name are purple mud pottery, make pottery with Jiangsu purple sand ceramics, Yunnan Jian Shui pottery, Chongqing Rongchang County and claim China four
Big name pottery.Nixing pottery is a wonderful work in Chinese national culture art, there is very long manufacture craft, and great culture is received
Hiding value, it may have very strong practicability.Blank used in Nixing pottery is finely free from foreign meter, and manufactured pottery kitchenware stomatal frequency is suitable
In, the fresh-keeping effect of drink can be played.Meanwhile the additives such as any preservative are not added in Nixing pottery preparation process, finished product is not
Containing any toxic component, used as kitchenware, it is very healthy and safe.Nixing pottery molding blank moisture content is higher, it is necessary to after dry
Can kiln-firing, when by heated drying, moisture evaporation of the maceration between clay particle is close to each other between particle, squeezes, generates
Internal stress, this internal stress can cause blank deformation even to crack.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of drying means of Nixing pottery, when this method can offset dry
Broken base stress is generated, avoids being deformed and cracking in the drying process.
Technical solution provided by the invention is a kind of drying means of Nixing pottery, and BaO is mixed in blank, and green body is made,
Then wavelength is used to be incident upon moisture content not higher than 2% for 10~30 μm of Far-infrared spoke green body.
Montmorillonite is most important plasticity ingredient in Nixing pottery blank, has biggish surface charge density and specific surface
Product, high surface activity can form the thicker Adsorbent-adsorbate interaction energy film with viscosity, enhance intergranular cohesive strength, one
Fixed consolidation pressure acts on contact point between lower particle and is small and easy to slide, and shows lower shearing strength.That is
Montmorillonite is the arch-criminal that Nixing pottery green body is easy cracking in the drying process.
The present invention is dry using far infrared radiation, under the conditions of infra-red radiation, montmorillonite lattice vibration, and Si-O and Al-O
Key produces fracture, to generate crystal defect, alkaline earth oxide enters montmorillonite lattice, the Ba of divalent2+Replace Si4+
And Al3+Montmorillonite crystal grain negative electrical charge is caused to increase, so that the repulsive force between montmorillonite particle is substantially increased, in this way dry
When dry, intergranular electrostatic repulsion can alleviate water loss and squeeze cohesive force to green body bring, thus slow down green body contraction,
Avoid dry bring blank cracking.Wavelength is used only to will cause Montmorillonite Crystal defect for 10~30 μm of far infrared radiation,
It is unlikely to that crystal is caused thoroughly to destroy, the intact of montmorillonite could be converted into mullite structure in subsequent firing, complete green body
Sintering.
The incorporation of BaO is the 0.1~0.2% of billet weight, this is because the excessive repulsion mistake that will lead between green body
Greatly, it is difficult to which dry, the too small too small montmorillonite dehydration bring that can not effectively offset of electrostatic repulsion that will lead to breaks base stress.
The temperature of the far-infrared radiation source is 80~150 DEG C.Distance of the far-infrared radiation source apart from green body is 10
~20cm.It is to avoid montmorillonite rapid dehydration from bringing excessive to guarantee that green body is heated more slowly that such parameter, which is arranged,
Broken base stress.
The radiation source of the far infrared radiation is Far infrared radiant panel.
The blank is to be mixed by eastern mud, western mud by weight 4~6:6~4.
Preferably, the weight ratio of eastern mud and western mud is 6:4.
Compared with prior art, the present invention can substantially reduce the deformation of green body in the drying process using far infrared radiation
And cracking, it is particularly evident for the effect of large-scale vessel.
