Abstract
The invention discloses a lead-free open-flame fast-firing full-frit bone-china glaze and a preparation method for the same. The lead-free open-flame fast-firing full-frit bone-china glaze comprises the following raw materials in percentage by mass: 42-60% of SiO2, 8-15% of Al2O3, 0.5-6% of B2O3, 8-16% of CaO, 0.4-2.6% of MgO, 3-9% of K2O, 0.5-5% of Na2O, 0-2% of Li2O and 4-20% of ZnO. The bone-china glaze disclosed by the invention is wide in application range, good in glaze slip flowability, wide in firing temperature, reasonable in process flow and reduced in use cost. With the adoption of the bone-china glaze disclosed by the invention, a glaze surface can meet standard requirements, the firing temperature can be reduced, the firing period can be shortened, the energy expense can be greatly reduced, and the market competitiveness of products can be enhanced.
Description
Technical field
The invention belongs to the enamel field, be specifically related to a kind of unleaded flaming and burn soon fine melt piece sclerotin enamel and preparation method thereof.
Background technology
Along with the raising of social life level, people are to self healthy pay attention to day by day.In the past the glaze that uses of domestic ceramics all more or less contain lead because lead is strong fusing assistant, also be strong developer, former to lead during without mandatory requirement, in the Glaze for chinaware a large amount of introduce plumbous; And now daily town of porcelain is had mandatory requirement to plumbous cadmium etc., and plumbous stripping there is strict requirement, particularly the high-grade porcelain as Bone China requires tighter; And along with the climbing up and up of energy prices, requiring save energy, the requirement that reduces manufacturing cost is also more and more stronger.And the production of traditional household china all is to adopt high temperature basically, and the cycle, major part was also used muffle burn generally all more than tens hours; Therefore, change the process for calcining of traditional domestic ceramics, change flaming into by the muffle burning and burn till, change warm quick fever into by high temperature.
Summary of the invention
The purpose of this invention is to provide the preparing ceramic clinker of the fast lead and cadmium free of burning of a kind of middle temperature flaming and its manufacture method.Solve existing sclerotin enamel all more or less contain lead, and the overwhelming majority all is only applicable to muffle burn; Can not satisfy the requirement to environmental protection of household china, to energy-saving and cost-reducing requirement.

Further, described temperature of founding is 1540～1570 ℃.
Its concrete steps are: raw material advances factory, check, batching, check batch mixing uniformity coefficient, founds, checks the degree of founding, shrend, check, to qualified frit packing.
The present invention can reach following beneficial effect after adopting technique scheme:
1, the scope of application is wide: the present invention both can be used on the Bone China that flaming burns till, and also can be used on the Bone China of muffle burn.
2, glaze slip is mobile fine: the glaze slip that the present invention makes is lower not thixotroping in working order, and when adopting glaze spraying, even spray very thinly, glaze also can flatten after the spray, does not have ripple.
3, firing temperature is wide: glass melting temperature of the present invention is at 1530-1570 ℃, and frit is without raw material, is transparent light blue; Use temperature is at 1110-1160 ℃.
4, technical process is reasonable: the high-grade bone china product that adopts the present invention to produce, and its whiteness is the color of sclerotin itself, and glaze is flat, and free of pinholes has good light transmission; Occupy at present advanced international level.
5, reduced use cost: employing the present invention not only glaze can satisfy standard-required, also can reduce firing temperature, shortens firing period, greatly reduces energy expenditure, strengthens the competitiveness of product in market.
Embodiment:
Below in conjunction with specific embodiment the present invention is described in further detail.(unit is mass percent).
