Description
Technical field
The present invention relates to a kind of ceramic and preparation method thereof, particularly relate to full porcelain flameproof ware of a kind of high pressure resistant high strength and preparation method thereof.
Background technology
Pottery, owing to having indeformable, the easy to clean and safety and sanitation of not burn into, is widely used in people's daily life as food utensil; Market there has also been miscellaneous daily heat resisting porcelain product simultaneously, but be mostly ceramic matt glaze easy fired series, intensity is not high, water-intake rate is large, and common heat-resisting potter's clay color is gloomy, manufacturer sprays black glaze or bright color glaze mostly for hiding potter's clay color, causes ceramic marmite series products also to there is hidden danger in hygienic safety.Though also have the pan of porcelain at present on the market, not resistance to rapid heat cycle, a dry combustion method is just easily ftractureed; These problems all seriously govern the share of the heat-stable ceramic product occupying inter-national market of China, and are difficult to meet the demand of domestic market to expensive goods.Chinese patent Authorization Notice No. CN102320813 B, the day for announcing is on April 2nd, 2014, this patent of invention discloses " a kind of heat-resistant ceramic edible vessel that can burn on naked light and production method thereof ", although the pottery that the program is produced can burn on naked light, can be used as pan cooking foodstuffs, make great progress than the heat-stable ceramic on former market, but these vessel due to its intensity not high, not high pressure resistant, can not use under high temperature and high pressure environment, its range of application is restricted.Along with the development of science and technology, mechanize washing, sterilization equipment are widely used, electric pressure-cooker, various microwave oven, light-wave cooker also progress into common people house, and this will certainly propose higher requirement to aspects such as the mechanical property of ceramic product, thermostabilitys.
Summary of the invention
For overcoming above-mentioned deficiency, the object of the present invention is to provide full porcelain flameproof ware of a kind of high pressure resistant high strength and preparation method thereof, with the flameproof ware that the method is produced, there is good mechanical property and thermostability, intensity is high, can adapt to use under high temperature and high pressure environment.
The technical solution adopted for the present invention to solve the technical problems is: the full porcelain flameproof ware of-kind of high pressure resistant high strength, and the weight percent of its blank and glaze formula consists of:

In said components, ripe quartz is the middle particle of 10 ~ 30um, and ripe aluminum oxide is the particle powder of 1 ~ 3um, and zirconium white is the fines of 3 ~ 5um;
Glaze: quartz 14 ~ 20%, ripe clay 20 ~ 25%, atomized aluminium 4 ~ 8%, talcum 3 ~ 6%, calcite 24 ~ 28%, kaolin 10 ~ 12%, boric acid 14 ~ 18%.
The preparation method of the full porcelain flameproof ware of above-mentioned high pressure resistant high strength, its processing step comprises:
(1) Slug preparing: prepare burden by above-mentioned blank formulation, lithium china clay, ripe quartz, kaolin, ball clay, talcum are washed mud, zinc oxide adds water and carry out wet ball grinding, reach fineness 325 mesh screen residue less than 0.5%, again aluminum oxide powder, zirconia powder are carried out dispersion treatment, add in above-mentioned blank and mix, by-deironing-press filtration-pugging-old (more than 10 days) of sieving, for subsequent use for the base mud going out moisture 19 ~ 21%;
(2) glaze preparation: by above-mentioned glaze formula batching, described material is made particle under 40 mesh sieves, drop into smelting furnace and carry out melting, smelting temperature is 1480 ~ 1500 DEG C, makes the frit of glass flake for subsequent use when coming out of the stove by bundle embrane method;
Frit is dropped into ball-grinding machine mill 20 ~ 25 hours, frit powder to 200 mesh sieves of dry grinding is for subsequent use;
Get frit 55% by weight percentage, methylcellulose gum 0.3%, water 44.7% mixes, drop into ball-grinding machine mill 14 ~ 16 hours, fineness reaches 325 mesh screen residues 0.1%, goes out honed 250 mesh sieves, is that finished product glaze slip is for subsequent use after deironing;
(3) base substrate makes shaping;
(4) shaping base substrate is dried;
(5) repaired biscuit;
(6) biscuiting: firing temperature 1340 ~ 1360 DEG C, firing time is 11 ~ 12 hours, and soak 50 ~ 60 minutes;
(7) glazing;
(8) glaze firing: firing temperature 1180 ~ 1220 DEG C, firing time 5.5 ~ 6.5 hours, and soak 30 ~ 40 minutes;
(9) check, pack, put in storage.
Its processing step (3) makes and is shaped to roll forming.
Its processing step (3) makes and is shaped to impact briquetting.
The product that the present invention obtains has the following advantages:
(1) product base substrate in material by adding lithium china clay, utilize that lithium china clay is stable, resistance to thermal property, be equipped with the raw materials such as quartz, kaolin, commercial alumina, make product excellent in cushion effect, center resistance to impact shock 52.59 lbf/in2, edge shock resistance 0.6 ft.1bf; Heat stability is good, can reach in 800 DEG C of inputs, 20 DEG C of water and not burst; The complete porcelain of product, water-intake rate reaches 0.01 below ℅, reaches full porcelain standard; Whiteness 80-85, glossiness all reach the standard of high-grade daily-use fine.
(2) product application scope is wide, can be made into various pan, adapts to explode under various thermal source, fries, stewes, product of cooking, and the using function of the heat-resisting pot of beyond tradition, detected by authoritative institution, do not exceed only traditional heat-resistant standard, and it is high pressure resistant, product is through twice firing, regularity, precision is high, can as the electric pressure cooker inner bag be widely used at present, heat-transfer rate is not second to original metal inner tube after testing, heat-insulating property is also good than metal inner tube, more energy-conservation, the non-sticky metallic coating health of the glaze paint of light more original metal inner tube again, safety, make to cook the rice taken and both remain original meter of perfume (or spice) and softer, more agreeable to the taste, the soup stewed out can keep raw material delicate flavour, more fresh and sweet good to eat.
(3) vessel made directly can enter barbecue in microwave oven, also can at refrigerator cold-storage, and dishwasher, stands the test of long-term rapid heat cycle, has good thermal stability; And product strength is high, not cracky, have heat conduction fast, heat radiation is slow, has the feature of SuperPro temperature, after being heated to boiling point, only needing minimum fire, just can keep constantly boiling, energy-conserving and environment-protective; And arbitrarily can do on glaze, in glaze and decorate; Add antimicrobial nano composition in glaze, burn till through high temperature, make glaze paint homogeneous full, hardness is high, and anti acid alkali performance is strong, and the effect that light glaze makes product naturally cannot not reach stickyly, need not re-use non-sticky metallic coating, use safer health.
