Description
Technical field
The present invention relates to the manufacture method of pottery, be specifically related to the manufacture method of Nixing pottery stem grafting sticking clay.
Background technology
Some Nixing pottery product can not one-shot forming, need base substrate main body and adnexa are made molding respectively,
Then with sticking clay, main body become with accessory adhering a complete base substrate.Modal have kettle, tank etc. main
Body and mouth, bonding, the adnexa such as ear, cap handle.Bonding being divided into wet connecing and stem grafting, stem grafting refers to base
The moisture content of phosphor bodies and adnexa carries out bonding when about 2%, and the moisture content of sticking clay is 25～27%,
Owing to base substrate has parched, differing huge with the moisture content of sticking clay, both dry shrinkage are inconsistent,
Shrinkage stress will be produced, cause the cracking of adnexa.On the other hand, the base substrate of overdrying and sticking clay is wet
Degree gradient is too big, and moisture is increased to the diffusion velocity of base substrate by sticking clay, causes the violent contraction of mud,
Producing stress, meanwhile, the current that excessive diffusion velocity is formed may drive a part of subparticle embedding
Enter the gluing of surfaces of base substrate, block pore, stop the continuation diffusion of moisture, also result in adhesive linkage thickness
Granule is layered, and also can affect bulky grain and embed base substrate, thus cause coming off of adnexa.
Summary of the invention
The technical problem to be solved in the present invention is to provide the manufacture method of a kind of Nixing pottery wet dry joint mud, should
The stem grafting sticking clay that method is made, in the case of moisture content is relatively low, still has preferable mobility
Good, bonding force is strong, and plasticity is preferable, can reduce season cracking.
The technical scheme that the present invention provides is a kind of manufacture method improving Nixing pottery stem grafting sticking clay, including
Following steps:
1) raw material of following weight portion is weighed: east mud 3～4 parts, western mud 3～4 parts, cordierite 1～2
Part, breeze 1～2 parts, Anhydrite 0.5～1 part；
2) by east mud, the mixing of western mud, wear into mud through ball mill, filter, compacting mud bar, vacuum pugging,
Old, obtain A pug；
3) cordierite, breeze and Anhydrite are mixed, wear into mud through ball mill, filter, suppress mud bar,
Vacuum pugging, old, obtain B pug；
4) A pug and B pug are mixed, be stem grafting sticking clay；The moisture content of described stem grafting sticking clay
It is 10～15%.
The stem grafting technique of complete Nixing pottery is as follows:
1) blank is prepared: east mud and western mud are mixed by weight for 6:4, through ball milling 8h, then depend on
Secondary mistake 40 mesh and 100 mesh twice sieve, suppress filtrate mud bar, vacuum pugging, old 15 days, be
Blank.
2) blank forming: blank is respectively prepared main body and the adnexa of Nixing pottery base substrate, controls main body and attached
Part moisture content when 2%, with moisture content be 10～15% stem grafting sticking clay its bonding one-tenth is completed
Base substrate.
3) body drying: base substrate is dried in the shade naturally.
4) fire: base substrate is sent kiln-firing, kiln discharge, is Nixing pottery.
For Nixing pottery blank, wherein SiO2Content is 64～65%, Al2O3Content is 16～17%,
Fe2O3Content is 5.1～6.8%, and the particle diameter of Nixing pottery blank is about 4 μm.
The theory of cordierite consists of: MgO:13.78%, Al2O3: 34.86%, SiO2: 51.36%.
SiO in cordierite2Content lower than Nixing pottery blank, and MgO, Al2O3For contributive to high-temperature liquid-phase
The content of eutectic oxide is higher than Nixing pottery blank, and therefore, adding cordierite in sticking clay formula can
To reduce the sintering temperature of sticking clay so that in sintering process, sticking clay (includes than Nixing pottery base substrate
Main body and adnexa) liquid phase occurs earlier, these liquid phase substances can be to Nixing pottery base substrate liquid phase not yet occur
Diffusion, forms a transition zone on Nixing pottery base substrate, thus more efficiently by main body and accessory adhering
Together.
Breeze be mainly composed of SiO2: 33.76%, Al2O3: 11.37%, Fe2O3: 1.14%, CaO:
40.34%, MgO:11.21%, TiO2: 0.39%.Similarly, Al in breeze2O3、Fe2O3, CaO and
MgO is eutectic oxide contributive to high-temperature liquid-phase, and its total amount is higher than Nixing pottery blank, therefore,
In sticking clay formula, add breeze can reduce the sintering temperature of sticking clay, be in sintering process,
There is liquid phase earlier than Nixing pottery base substrate (including main body and adnexa) in sticking clay, and these liquid phase substances can be to
Not yet occur that the Nixing pottery base substrate of liquid phase spreads, one transition zone of formation on Nixing pottery base substrate, thus more
Add effectively by main body together with accessory adhering.
Anhydrite is conventional non-plastic raw material, can reduce sticking clay in the contraction being dried and in sintering process.
Additionally, Anhydrite crystal is en plaque or sheet-pile shape, cordierite crystal is short cylinder, and above-mentioned shape
The specific surface area of grain is bigger than the spherical particle of Nixing pottery blank, and en plaque, sheet-pile shape and short cylinder
Grain easily formation face contacts with face, and the capillary radius of composition reduces, and enhances the stream of stem grafting sticking clay
Dynamic property, enhances adhesive effect, and again due to the addition of breeze, its corner angle are many, symmetry is poor, to granule
The resistance that relative displacement occurs is big, and then is greatly enhanced the plasticity of sticking clay.
Therefore, sticking clay mixes cordierite, Anhydrite and breeze and can reduce the firing temperature of sticking clay,
Being allowed in sintering procedure, produce substantial amounts of high-temperature liquid-phase prior to Nixing pottery base substrate, these high-temperature liquids are met
Towards main body and the adnexa diffusion of Nixing pottery base substrate, thus main body and adnexa are firmly clung so that adnexa
Difficult drop-off.By the interaction between Anhydrite, cordierite and breeze, not only increase sticking clay
Adhesion, also enhances the plasticity of sticking clay, it is to avoid be dried and sintering process in base substrate cracking and
Come off.
Step 2) in, mud is crossed successively 100～150 mesh and 200～250 mesh sieves, takes filtrate compacting
Mud bar, vacuum pugging, old 5～7 weeks, obtain the A pug that particle diameter is 1～2 μm.
Step 3) in, mud is crossed successively 200～250 mesh and 300～350 mesh sieves, takes filtrate compacting
Mud bar, vacuum pugging, old 6～8 weeks, obtain the B pug that particle diameter is 0.5～1 μm.
The particle diameter of the A pug in sticking clay is 1～2 μm, and B pug particle diameter is 0.5～1 μm, and mud is emerging
The particle diameter of greenwave material is that the grain diameter of 4 μm, i.e. sticking clay is less, and specific surface area is relatively big, thus piles up
Capillary radius the least, the capillary force of generation is the biggest so that sticking clay does not show at moisture content
Write, higher than in the case of base substrate, also there is preferable mobility, enhance the adhesive effect of sticking clay.Not only
So, the particle diameter of A pug differs with B pug particle diameter, and the interface that size particles contacts exists limit wall
Effect, porosity is higher, defines larger-size diffusion admittance, enhances the mobility of sticking clay,
Thus strengthen adhesive effect.
Therefore, reduce the grain diameter of sticking clay, be less than Nixing pottery blank particle diameter, can strengthen and connect
The mobility of head mud, it is simple to each component particles mutually shifts near and draws close, strengthens cohesive force；And A in sticking clay
Pug and B pug grain diameter differ, and contribute to being internally formed bigger diffusion admittance at sticking clay, enter
One step strengthens the mobility of sticking clay, thus strengthens adhesive effect.
The method have the advantages that
1) the stem grafting sticking clay moisture content that the present invention makes is only 10～15%, connects well below conventional stem grafting
The moisture content of head mud, so can ensure that and is dried with in sintering process at sticking clay, moisture shrinks less,
Shrinkage stress is less, thus is substantially reduced adnexa cracking probability.Meanwhile, sticking clay is terraced with the humidity of base substrate
Spend less, adhesive linkage large or fine granule can be avoided to be layered, and then be substantially reduced adnexa and come off probability.
2) the stem grafting sticking clay of the present invention is in the case of moisture content is only 10～15%, still can ensure that relatively
Good mobility, accessory adhering is effective, difficult drop-off.
3) the stem grafting sticking clay of the present invention is used Nixing pottery base substrate to be carried out stem grafting, with the small-sized vessel of Nixing pottery
As a example by, stem grafting burns till rate up to more than 85%.
