Description
Technical field
The present invention relates to ceramic processing technique field more particularly to a kind of processing methods of ceramic raw material.
Background technique
Ceramics are to be kneaded, form and calcine various systems obtained by crushing using clay, quartz and feldspar as primary raw material
Product.
Existing Ceramic manufacturing method includes the gypsum mould grouting method of forming and mouldability material object completion method, wherein gypsum
Ceramic material is made into sample first by mould slip casting, then carries out piecemeal synthesis with the plaster of paris and overmolded is cast into gypsum mother
Mould, then ceramic mud is poured with plaster master, finished product is made in demoulding after ceramic mud is dry.Mouldability material object completion method is adopted
Disk builds up type by hand or the molding mode of mudcake makes, and in the production process, since pug intensity is low, needs to be carried out with material object
Filling support is to enhance its intensity.
But the fabrication cycle of the above-mentioned gypsum mould grouting method of forming is longer, operation difficulty is larger, also has process more and multiple
Miscellaneous disadvantage, the green body after shaping and drying is easy to crack and unrepairable.It is increased after the filling of mouldability material object completion method is in kind
The weight of green body is not easy to remove after dry, and green body inner wall is thicker, and pug used is more, leads to higher cost.In addition, pottery
Porcelain pug itself causes its ductility lower due to the property of raw material and the limitation of manufacture craft, and then leads to ceramic product
Moulding is single, lacking individuality.
Summary of the invention
The present invention provides a kind of processing method of ceramic raw material, easy to crack to solve the green body that existing processing method is processed into
And unrepairable and the lower problem of pug ductility.
The present invention provides a kind of processing method of ceramic raw material, comprising:
It is soaked in water after taking former wood pulp paper to smash to pieces 1-2 days, obtains initial pulp；
The initial pulp is put into high-speed mixer, the revolving speed for controlling high-speed mixer is 600-800r/min, will
The initial pulp stirs evenly, and obtains paper pulp, and the moisture content of the paper pulp is 5-10%；
It takes ceramic raw material to be uniformly mixed with water, obtains pug, the moisture content of the pug is 15-25%；
The paper pulp is uniformly mixed with the pug, obtains mud, the mass ratio of the paper pulp and the pug is (1-
3): 10, the moisture content of the mud is 35-45%；
It takes pure cotton cloth or ramie fabric to immerse in the mud, after the mud described in the pure cotton cloth or ramie fabric uniform adsorption, takes
Pure cotton cloth or ramie fabric cover on backing material out, and pure cotton cloth or the moulding of ramie fabric surface after adsorbing mud obtain base
Body；
The dry green body.
In one embodiment of the invention, the pure cotton cloth or ramie fabric are by the line of diameter 0.5mm with every square centimeter
10 warps and 10 wefts weave.
In one embodiment of the invention, the backing material is paper or balloon.
In one embodiment of the invention, the moisture content of the pug is 20%.
In one embodiment of the invention, the moisture content of the mud is 40%.
Pug and paper pulp are mixed and made into mud by a kind of processing method of ceramic raw material provided by the invention, and paper pulp adds
The problem of entering the ductility and toughness that can effectively promote pug, reducing frangible in ceramic forming process and cracking, additionally it is possible to mention
Rise the intensity of green body；It is immersed in mud with pure cotton cloth or ramie fabric, then on backing material to being adsorbed on pure cotton cloth or pure fiber crops
Mud moulding on cloth, can effectively reduce the dosage of pug, reduce cost, additionally it is possible to shorten the drying time of green body, in addition,
Since pure cotton cloth or ramie fabric are more soft, texture and pleat that the pure cotton cloth for having mud or ramie fabric are showed at the time of molding
Wrinkle is more clear, and is operated in forming process more convenient flexible.
