Description
Affiliated technical field
The present invention relates to ceramic fabrication technique field, specifically a kind of Chinese medicine stone ceramic goods.
The invention still further relates to the preparation method of Chinese medicine stone ceramic goods.
Background technology
A host of facts show, contain the indispensable trace element of multiple human body and animals and plants in medical stone, and excellent adsorption, and dissolution rate is fast, very easily by animals and plants, is absorbed.Meanwhile, medical stone or a kind of Chinese medicinal materials of preciousness, can get rid of toxicant and harmful germs such as lead harmful in human body, mercury, tin, arsenic.Therefore, medical stone has special effect at aspects such as health care, disease preventing and treating, prevent cancer and delay sanility and purification of water qualitys.In order to utilize better the above-mentioned characteristic of medical stone, people are processed into various cups, pot for cooking rice by medical stone building stones in recent years, and by absorption of human body, its trace element releasing reaches the object of health care.But medical stone quality is more crisp, there is tomography the centre of most medical stone piece material, so the difficulty of processing and fabricating medical stone goods is large, cost is high, and this has affected the exploitation of medical stone to a certain extent.
In order to make full use of maifanshi resource, further improve the quality of medical stone apparatus, some contriver has proposed medical stone and other mineral materials to mix rear calcining in recent years, and trial substitutes MUSYUSHI with medical stone or purple clay is fired the Chinese medicine stone ceramic goods with nourishing function.If number of patent application is 200910118859.1, denomination of invention is < < medical stone sintering vessel and preparation method thereof > >; Number of patent application is 201210254431.1, and denomination of invention is < < medical stone fictile and preparation method thereof > >, etc.Yet, up to the present on market, there is not the Chinese medicine stone ceramic product that a technology is relatively ripe.Trace it to its cause and be mainly above-mentioned medical stone goods, its inadequate science of batching, preparation technology is not mature enough.Such as, with regard to medical stone and other mineral aggregate of selecting, the content difference of its various compositions is very large, if the purity of various mineral aggregates is not high, fusing point is different, is just difficult to burn out qualified Chinese medicine stone ceramic goods.
Summary of the invention
In order to make full use of maifanshi resource, further improve the characteristic of medical stone goods, the invention provides a kind of reasonable ratio, craft science, Chinese medicine stone ceramic goods that production cost is lower.
Another object of the present invention is to provide the preparation method of described Chinese medicine stone ceramic goods.
The technical solution adopted for the present invention to solve the technical problems is: this Chinese medicine stone ceramic goods, raw material by following weight percent is made: medical stone powder 41～45%, feldspar in powder 16～20%, albite in powder 10～14%, silica powder 8～12%, Laiyang soil 12～17%; Described medical stone powder, its dioxide-containing silica is greater than 60.00%, and alumina content is greater than 14.00%, and sodium oxide content is greater than 4.00%; Described feldspar in powder, its potassium oxide content is greater than 10.00%, and iron oxide content is less than 0.30%; Described albite in powder, its sodium oxide content is greater than 8.00%, and iron oxide content is less than 0.30%; Described silica powder, its dioxide-containing silica is greater than 98.00%, and iron oxide content is less than 0.10%; Described Laiyang soil, its dioxide-containing silica is less than 75.00%, and alumina content is greater than 13.00%, and iron oxide content is less than 1.00%.
The method of preparing Chinese medicine stone ceramic goods comprises the following steps:
(1), by described weight percent, take raw material, pulverized 100～150 mesh sieves, mixed rear standby;
(2), according to material, ball, the water ratio of 1: 2: 0.5, above-mentioned powder is ground 1～2 hour in ball mill, mud filters, makes finished product mud after pugging through 320～350 eye mesh screen;
(3), injection forming, after the demoulding, revise polishing, dry in the air 12～24 hours;
(4), finally in stove, the mud embryo drying is carried out to multi-steps sintering, cooling, make desired product;
Described multi-steps sintering is: the first stage, from normal temperature to 900 ℃, temperature rise rate is 4.2～4.5 ℃/min, calcines 3 hours; Subordinate phase, from 900～1200 ℃, temperature rise rate is 2.4～2.6 ℃/min, calcines 2 hours; Phase III, from 1200～1300 ℃, temperature rise rate is 3.2～3.3 ℃/min, calcines 0.5 hour; Fourth stage, is cooled to normal temperature from 1300 ℃, 15～20 hours time, obtains desired product; Described normal temperature is 25～35 ℃.
Beneficial effect of the present invention: be mainly batching science, make the performance of medical stone obtain better improvement.Medical stone is silicate minerals, and chemical composition is close with silicon ash, and iron, titanium content are high, and bonding strength is low, and plasticity-is little.For this reason, in batching, add Laiyang soil that plasticity is good, added bonding strength is high, have consolute characteristic potassium felspar sand and albite simultaneously.When sintering temperature rises to 1200～1250 ℃, two kinds of mineral aggregates of potassium felspar sand and albite start gradually to melt, and have brought into play good gummed effect in whole raw material.Particularly guaranteeing that medical stone goods have on the basis of some strength, density, also make this product there are the many micropores larger than natural medical stone aperture, thereby this goods dissolution rate piece, excellent adsorption, makes this product than natural medical stone, have better effect aspect body-care, function of anti-cancer and cancer prevention.Shandong Center for Disease Control & Prevention of assert through country, shows the whole conformance with standard of institute's inspection project to the detected result of 15 projects such as the lead in Chinese medicine stone ceramic goods, mercury, arsenic, volatile phenol, chromium.The pH value of goods soak solution is 8.39, is weakly alkaline.Especially the various trace elements that the human bodies such as the iron that medical stone is separated out, copper, zinc, strontium need in sample soak solution, detected.
Secondly, take multi-steps sintering, improved the yield rate of Chinese medicine stone ceramic goods.The bag water-based of medical stone mud, moulded pottery not yet put in a kiln to bake is poor, drying shrinkage is little, in calcination process, easily ftracture, be out of shape, and long interval time for mineral aggregate melting, melt viscosity high, the way that take calcine by steps, progressively heats up, strictly grasps time and the temperature of sintering, make moulded pottery not yet put in a kiln to bake experience steadily shrink, melt gummed, porcelain and change into type, stage such as cooling progressively, guaranteed the quality of medical stone goods.By statistics, sintering finished rate of the present invention reaches more than 97%.
