Description

A kind of nano quartz sand ceramic ware for daily use

Technical field

The present invention relates to ceramic ware for daily use, be specifically related to a kind of nano quartz sand ceramic ware for daily use and manufacture craft thereof.

Background technology

Pottery has long use history in China, nowadays widely use in worldwide, domestic ceramics has just like become a part indispensable in people's daily life, panoramic tableware, tea set, all kinds of sanitary equipment etc. are seen everywhere, these potteries are not only elegant in appearance, various shapes, also there is easy cleaning simultaneously, heatproof, the advantages such as wear resistant corrosion resistant, be well received by consumers, but ceramic product universal existence is crisp, not shock-resistant, poor toughness, glaze colours inequality easily comes off, the shortcomings such as production energy consumption is large, cause its breakage in production and transport and application process more serious, thus increase production cost, therefore in the urgent need to improving its performance, promote domestic ceramics industry to low cost, environmental protection future development.

Summary of the invention

The object of the invention is to, provide a kind of nano quartz sand ceramic ware for daily use, to improve the performance of conventional quartz sand ceramic, reduce production cost, to achieve these goals, the technical solution used in the present invention is as follows:

A kind of nano quartz sand ceramic ware for daily use, it is characterized in that, material of the present invention is made up of the raw material of following weight part: carclazyte 10-12, potassium felspar sand 30-34, Stalactitum 23-25, nano quartz sand 40-45, saltpetre 10-12, aluminium sesquioxide 20-23, barium sulfate 4-6, magnesium chloride 4-5, carbide slag 6-8, perlite 10-12, sepiolite 30-35, auxiliary agent 5-6.

Described auxiliary agent is made up of the raw material of following weight part: brown alundum powder 2-3, tripoly phosphate sodium STPP 5-6, jade powder 4-5, silane resin acceptor kh-550 1-2, carborundum powder 4-5, aluminium hydroxide 8-10; Its preparation method is by each mixing of materials, and grinding distribution is even, to obtain final product.

Described a kind of nano quartz sand ceramic ware for daily use, its manufacture craft comprises following steps:

(1) first potassium felspar sand, Stalactitum, carbide slag, perlite, sepiolite are pulverized, cross 100-200 mesh sieve;

(2) by the mixing of materials that other remaining component except auxiliary agent and step (1) obtain, add grinding in ball grinder, cross 400-600 mesh sieve;

(3) added by auxiliary agent in the material that step (2) obtains, after stirring, add water and make stock, stock is moulding after deironing, thick experienceds, old, refining processing must idiosome;

(4), after idiosome drying, cleaning, glazing, at 1318-1345 DEG C of temperature, sinter 15-18 hour, get product.

The invention has the advantages that: the character utilizing nano quartz sand uniqueness, make it under relatively low firing temperature, generate heat-staple idiosome, avoid the idiosome phenomenon easy to crack that conventional quartz sand pottery causes because thermal expansivity is large, to arrange in pairs or groups again other raw material, impart the good thermostability of ceramic of the present invention and chemical stability, its mechanical property also improves simultaneously, and wear resisting property is excellent, whiteness is high, uniform color becomes clear, and attractive in appearancely has concurrently with practicality, has wide range of applications.
