Description
Technical field
The present invention relates to a kind of pottery, be specifically related to a kind of anti-bacteria ceramic containing Chinese medical extract and preparation method thereof.Belong to ceramic technology field.
Background technology
The various goods that pottery is is the material that main raw material is mixing, shaping through pulverizing and calcining is obtained with natural clay and various natural mineral.Along with the high speed development of economic society, the quality of life of people improves day by day, and consumption idea also constantly changes, in the selection of ceramic, not merely can pay close attention to its practicality, artistry and sight, also it is functionally had higher requirement, particularly more and more higher especially to the demand of germ resistance.Have the ceramic of antibacterial, it is in Ceramic Production process, adds inorganic antiseptic, thus makes ceramic surface have a kind of new function pottery of anti-microbial effect.Anti-bacteria ceramic, as functionality ceramic product, can effectively avoid various communicate illness to the sanitary precaution of the infringement of the mankind, particularly public place.Current anti-bacteria ceramic mainly realizes germicidal action by interpolation titanium oxide, silver, rare earth element or medical stone and far-infrared material antiseptic-germicide.But existing anti-bacteria ceramic or production cost high being unfavorable for promote the use of on a large scale, otherwise responsive to light and heat, and the outward appearance of easy blackening impact light color pottery, the most important thing is, antibacterial effect is all not ideal enough.
Plant Purpleflower Crotalarla Herb is annual upright draft, high 20 ~ 100 centimetres, and be close to slightly long hair, hair is slightly coarse.Dan Ye, linear or lanceolar, leaf blade size alters a great deal, long 2.5 ~ 8 centimetres, wealthy 0.5 ~ 1 centimetre, the narrow point in two ends, and tip has pencil hair usually, above slightly by hair or several without hair, drapes over one's shoulders mercerising matter hair below; Several without petiole; Stipule is superfine little, setiform.Raceme, top is raw or armpit is raw, and spend 2 ~ 20, flower is together intensive.Bract and bractlet fairly similar, linear; Bractlet and is born in bennet top, is all become mildewed by roughish; Bennet is extremely short, sagging during result: calyx is long 10 ~ 15 millimeters, is closely become mildewed by brown color, calyx tooth tip point; Corolla butterfly, hyacinthine or light blue, about isometric with calyx, vexil is circular, and ala is short compared with vexil, the shape of falling ovum square circle, keel and ala isometric, interior curved, tool beak; Stamen 10, monomer, flower pesticide 2 type; Ovary stockless, style is elongated.Pod without hair, Long Circle, about isometric with calyx; 10 ~ 15, seed.September at florescence.Be born in the weeds of wasteland.Distribution northeast, East China, south China and southwestern various places.
A kind of reed mentioned in ancient books has another name called first a kind of reed mentioned in ancient books, withered a kind of reed mentioned in ancient books, and head is loaded in Shennong's Herbal, is the dry root of labiate ScutellariabaicalensisGeorgi.Root of large-flowered skullcap bitter, cold in nature, there are heat-clearing and damp-drying drug, eliminating fire and detoxication, hemostasis, the effect such as antiabortive.Cure mainly febrile disease, upper respiratory tract infection, cough due to lung-heat, damp and hot jaundice, pneumonia, dysentery, hemoptysis, hot eyes, threatened abortion, hypertension, carbuncle swell the diseases such as furuncle sore.The root of large-flowered skullcap is one of China's tcm clinical practice conventional Chinese medicine kind, has long medication history, main product in Hebei, Shanxi, the Inner Mongol, the provinces and regions such as Liaoning, Russia East Siberia, Mongolia, Korea, all there is distribution in Japan.The root of large-flowered skullcap is mainly containing flavonoid compound, and the Flavone aglycone be separated from the root of large-flowered skullcap at present and glycosides have kind more than 40.In addition a large amount of diterpene-kind compounds and abundant trace element (wherein the content of iron, copper, zinc, manganese is all very high) is also contained in the root of large-flowered skullcap
Rhizoma Sparganii is the dry tuber of Sparganiaceae plant rhizoma scirpi SparganiumstoloniferumBuch.-Ham., from 1977, is recorded by each version " Chinese Pharmacopoeia ".It has broken blood gas, the effect of the long-pending pain relieving that disappears, and is conventional stasis-breaking drug; Zhu Zhi Disorder lump in the abdomen lump in the abdomen, hemostasis through closing, the card such as dyspepsia swelling, be used for treatment menoxenia, gather caking.Spring winter to next year excavates, and clean, crust of pruning, dries.Be distributed in northeast, the Yellow River, basin, the middle and lower reach of Yangtze River and Tibet.
