Description
Technical field
The present invention relates to sanitary ceramics production technical field more particularly to a kind of glazings for preventing sanitary ceramics from generating pore
Method.
Background technique
" sanitary ceramics glazed tile pinholing Producing reason and overcoming method " (Chinese pottery industry, in April, 2008 volume 15 the
2 phases, article are numbered: being pointed out in 1006-2874 (2008) 02-0028-04), " pore, pig pore, pin hole (being referred to as " pore ") "
Should belong to the glaze planar defect of same class difference call, feature should be it is small and more, can not measure, single say from standard angle does not belong to
In defect.And " pinhole " is just different, size should be than " pore " greatly, and quantity is few and limited, is otherwise just judged to rejected product." hair
Hole " and " pinhole " are also different in the origin cause of formation.
It is compiled by Chinese ceramics branch Jian Wei porcelain Professional Committee, silicate association, Chinese building material industry publishing house publishes
In " the construction sanitary ceramic engineer handbook " of (in August, 1998), there is the explanation of " pinhole " in sanitary ceramics Common Defect Analysis:
" pinhole refers on the green body under glaze layer, diameter within 1.5mm without glaze aperture " etc..
In summary, there are the following aspects for pore producing cause:
1) in terms of raw material the reason of: organic matter and carbonate content are too high in base glaze, when firing produced by gas discharge；
2) forming aspect the reason of: it is too urgent to operate when slip casting, make the gas in mud be not discharged suddenly or mud overheat hair
Ferment etc.；
3) the reason of dry aspect: body drying is impermeable, and gas is discharged when firing；
4) the reason of firing aspect: glaze viscosity is big, gas be not easy discharge or sintering curve is unreasonable, firing temperature not
It is enough.
Pore avoid method mainly include the following types:
1) base glaze is selected, controls the content of organic matter and carbonate in base glaze；
2) the suitable moisture of mold is kept before slip casting；
3) keep green body cleaning can not overdrying before glazing.
Method set forth above can be avoided the generation of pore, but in the actual processing process, these methods often relate to
And multiple processing steps, and technological parameter is more, is difficult to control, and it is inconsistent to eventually lead to each batch product glaze quality, and hair
Porosity can only generally be controlled in 8% or so (in i.e. same batch, the product accounting of pore phenomenon occur).
In view of this, the present invention has carried out process modification to glazing in the prior art operation, proposes one kind and be more suitable for
In the enameling method of sanitary ceramics, the generation of glazed tile pinholing can be more effectively avoided.
Summary of the invention
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of to prevent sanitary ceramics from generating pore
Enameling method.
The present invention is achieved through the following technical solutions:
A kind of enameling method for preventing sanitary ceramics from generating pore, comprising the following steps:
The pretreatment of S1 blank: blank surface is clean, for use；
Glaze: being sprayed at the blank surface handled through S1 and forms glaze by S2 blank glazing, and room temperature dries 4~12h, to
With；
S3 glaze surface treatment: magnesium chloride solution is sprayed on the surface of the embryo material handled through S2.
Further, in S2, before spraying glaze, water spray processing also is carried out to blank, and dry at 50 DEG C after water spray
20~30min.
Further, in S2 glaze sprinkling the following steps are included:
Glaze is sprayed on the blank through water spray processing by S2-1, after room temperature dries 30~50min, is continued in blank surface
Magnesium chloride solution is sprayed, one layer of glazing blank is obtained；
S2-2 continues to spray glaze on one layer of glazing blank, and after room temperature dries 20~30min, it is molten to continue sprinkling magnesium chloride
Liquid obtains two layers of glazing embryo material；
S2-3 repeats S2-2, completes glazing.
Further, by weight, the concentration of magnesium chloride solution is 30~60% in S3；Magnesium chloride is molten in S2-1 and S2-2
The concentration of liquid is 10~30%.
Further, by weight, the concentration of magnesium chloride solution is 40~50% in S3；Magnesium chloride is molten in S2-1 and S2-2
The concentration of liquid is 15~25%.
Further, by weight, the concentration of magnesium chloride solution is 45% in S3；Magnesium chloride solution in S2-1 and S2-2
Concentration is 20%.
Further, the jet velocity of magnesium chloride solution is 1~2ml/s in S3；Magnesium chloride solution in S2-1 and S2-2
Jet velocity is 0.5~1ml/s；Jet velocity is controlled, in order to avoid multipair glaze gloss was sprayed to causing adverse effect.
In above-mentioned technical proposal, the magnesium chloride solution of sprinkling can help the substances such as carbonate and sulfate in blank to exist
Decomposed completely before frit glass (glass transition temperature is at 1050 DEG C or so) (magnesium chloride solution is prepared by anhydrous magnesium chloride,
In blank sintering procedure, chemical reaction occurs first and generates basic magnesium chloride, the basic magnesium chloride of generation is then and in blank
The substances such as carbonate and sulfate react, so that the substances such as the difficult carbonate decomposed and sulfate are needed for frit glass
Gas is produced under temperature and is decomposed), the gas of generation smoothly penetrates glaze discharge, avoids forming pore in glaze；
The spraying of magnesium chloride solution, glaze and water, ejecta of being subject to cover entire blank.
Compared with prior art, the present invention has following usefulness:
1) it sprays water, soak blank shallow-layer and is filled into the stomata generated when blank drying to blank before glazing,
Part blank stock is dissolved with the dry water that carries out, these stomatas can be filled, and moisture rapid evaporation after drying, evaporation
New stomata is generated in the process and newly generated stomata is closer apart from blank surface layer, it is easier to which the glaze being attached on blank is filled out
It fills, the stomata generated when blank drying can be reduced；
2) magnesium chloride solution sprayed can help the substances such as carbonate and sulfate in blank in frit glass (glass
Glass temperature is at 1050 DEG C or so) it decomposes completely before, the gas of generation smoothly penetrates glaze discharge, effectively glaze is avoided to be formed
Pore；
3) multiple glaze spraying and the repeatedly operation of spray magnesium chloride are carried out, effectively controls pore rate 1~3%.
