Abstract
This invention relates to a method for making domestic porcelains such as: cups, plates, bowls, dishes, kettles, forks, spoons and tea wares (coffee wares), by using zirconium oxide as law material. The production procedures are: high density zirconium oxide powder is mixed with organic binder (polypropylene, paraffin wax or the like) with the proportion of oxide/binder=100:(10-30), then heated to 160-180deg.C for blending, fed into injection moulding machine (into the mould) under 150-200deg.C and 80-100MPa, finally cooling, demoulding to obtain the semi-finished products. after that, they are proceeded under wax-removing, being sintered to produce final products, with high strength and high toughness.
Description
Technical field
The invention belongs to a kind of new ceramics product and manufacture method thereof, be that a kind of high-performance zirconium oxide ceramics that utilizes is made the high-grade domestic porcelain of zirconium jewel specifically, comprise tableware for daily use, tea set and manufacture method thereof such as cup, dish, dish, bowl, cutter, fork, spoon, belong to the high technology for civilian use ceramic product and make the field.
Background technology
High-grade daily-use tea (coffee) tool is very popular always, the family and the outlet of particularly medium above income, and the demand of product increases year by year.At home and abroad, because special fine ceramic raw material reduces year by year, amount of product throughput reduces year by year, and up to 1000 pounds, the hair porcelain products that state light porcelain factory produces have also been sold for 10,000 Renminbi to the senior bone china coffee service, coffee set that a present cover Britain produces in the market selling price.
According to market study: the numeral that high-grade daily-use tea (coffee) tool annual requirement 1000000 covers are still relatively more conservative, therefore the high-grade daily tea (coffee) of exploitation has vast market and space.But at present domestic domestic ceramics all is some common ceramic making moulding, can't reach the requirement of high-grade porcelain at all, and because conventional ceramic intensity is low, wear no resistance, and toughness is relatively poor, be easy to broken, so be difficult to improve grade.Therefore necessary this is improved.
On the other hand, zirconia ceramics toughening ceramic material has the advantages that matter is white, corrosion-resistant, chemical stability is good; Absorb strain energy at stress induced generation martensitic transformation down, become mechanical property best material in stupalith; Promptly have the highest folding strength and fracture toughness property at normal temperatures, thereby toughened zirconia ceramics has outstanding wear resisting property.But now toughened zirconia ceramics only limits to and the zirconia ceramics toughening ceramic is applied in industries such as machinery, electronics, oil, chemical industry, space flight and weaving, as industrial pottery, it is not used for ceramic ware for daily use as yet, therefore, necessary this is studied.Have a wide range of applications and enormous and latent market in the domestic ceramics field as a kind of high performance pottery.
Summary of the invention
The objective of the invention is to: at the deficiency of existing daily necessities, provide a kind of new purposes of high-performance zirconium oxide ceramics, be used for the mining inetesity height, wear resistance is good, toughness is high, and be difficult for broken novel high-grade zirconium white daily necessities.
Another object of the present invention is to provide a kind of making method of above-mentioned high-grade zirconium white daily necessities.
The objective of the invention is to be achieved through the following technical solutions: adopt the zirconia ceramics powder stock to make daily necessities, comprise tableware for daily use, tea (coffee) tools such as cup, dish, dish, bowl, kettle, cutter, fork, spoon, be zirconium white daily necessities utensil.Because zirconium white itself has very high intensity, and the product that the superior performance of each side such as toughness, especially zirconium white are made have well-illuminated bright characteristics, and the feature of jewel is arranged very much, therefore high-grade daily tea (coffee) tool of making of zirconium white has the aesthetic feeling of zirconium jewel.
The making method of zirconium white daily necessities utensil is: adopt the injection moulding of high-density Zirconium oxide powder, at first with high-density zirconia powder and organic binder bond (polypropylene, paraffin etc.), in 100 parts of Zirconium oxide powders: the ratio weighing of 10-30 part organic binder bond, heating mixes to 160～180 ℃ is placed in the injection moulding machine, (80～100MPa) make a bet injects mould at certain temperature (150 ℃～200 ℃) and pressure then, the demoulding again after the cooled and solidified, can obtain the base substrate of zirconium white daily necessities utensil, carry out degreasing and sintering again, obtain the zirconium white daily necessities utensil of high-intensity high-tenacity.
The invention has the advantages that: because in different temperature ranges, zirconium white presents different crystalline structure: ℃ be monocline from room temperature to 1170,1170～2370 ℃ is tetragonal, and 2370～2706 ℃ is cubic structure.Advantages such as zirconia ceramics has the hardness height, wear resistance is good, toughness is high, frictional coefficient is low, good corrosion resistance, wear resistance is 15 times of alumina-ceramic, the coefficient of friction of zirconia ceramics is 1/2 of an alumina-ceramic only, and the coefficient of friction of alumina-ceramic own is very low.The density ratio aluminum oxide pottery of zirconia ceramics is higher, the density of alumina-ceramic is 3.5, and the density of zirconia ceramics is 6, and quality is finer and smoother, after attrition process, surface smoothness is higher, can reach more than 9, is mirror-like, dead smooth, therefore frictional coefficient is littler, makes zirconium white domestic ceramics utensil with zirconium white, has the hardness height, advantages such as wear resistance is good, toughness is high, frictional coefficient is low, good corrosion resistance.
