Ceramic rhaub manufacturers qhia txog kev faib cov ntaub ntawv raw
Kev faib tawm los ntawm lub hom phiaj
1. Txhua hnub siv cov ceramics: xws li tableware, tshuaj yej teeb, jars, altars, phiab, lauj kaub, phaj, phaj, tais, thiab lwm yam.
2. Art (craft) ceramics: xws li vases, sculptures, vaj ceramics, tais diav, rooj tog, thiab lwm yam.
3. Industrial ceramics: yog hais txog cov khoom siv ceramics siv hauv ntau yam lag luam. Nws tau muab faib ua 6 yam hauv qab no:
① Tsim kom muaj cov khoom siv huv huv: xws li cib, vuas, cov kav dej, tig ntsej muag cib, sab nrauv phab ntsa cib, cov khoom siv tu cev, thiab lwm yam.;
② Chemical (chemical) ceramics: siv nyob rau hauv cov kua qaub-resistant ntim, pipelines, towers, twj, li qub, thiab acid-resistant bricks thiab tshauv rau hauv ob sab phlu tshuaj tiv thaiv pots nyob rau hauv ntau yam tshuaj industries;
③ Hluav taws xob cov plooj (porcelain): siv rau cov insulators ntawm cov kab hluav taws xob siab thiab qis hauv kev lag luam hluav taws xob. Lub cev muaj zog bushings, post insulators, low-voltage hluav taws xob thiab teeb pom kev zoo insulators, telecommunications insulators, xov tooj cua insulators, thiab lwm yam.;
④Tshwj xeeb ceramics: cov khoom siv tshwj xeeb ceramics siv nyob rau hauv ntau yam kev lag luam niaj hnub thiab kev tshawb fawb thiab thev naus laus zis, suav nrog alumina ceramics siab, magnesia ceramics, magnesia ceramics, zircon ceramics, lithium ceramics, thiab magnetic ceramics, Cermet, thiab lwm yam.
Folding raws li qib ntawm cov khoom ntom ntom
Ceramic rhaub manufacturers
Stoneware (brickware los yog terra-cotta), zoo pottery (pottery), stoneware (stone Ware), semivitreous china (semivitreous china), thiab txawm porcelain (porelain), raw cov ntaub ntawv yog los ntawm ntxhib mus rau nplua, lub cev yog los ntawm ntxhib xoob. ntxeem tau, Maj mam ncav cuag qhov ntom ntom, sintering, thiab qhov hluav taws kub kub maj mam nce los ntawm qis mus rau siab.
Stoneware yog cov khoom qub tshaj plaws thiab qib qis tshaj plaws, feem ntau yog ua los ntawm cov av nplaum fusible. Qee zaum, clinker lossis xuab zeb tuaj yeem muab ntxiv rau hauv av nplaum kom txo qis qis. Qhov hluav taws kub kub ntawm cov khoom no txawv heev, nyob ntawm seb qhov xwm thiab tus nqi ntawm impurities muaj nyob rau hauv cov tshuaj muaj pes tsawg leeg ntawm av nplaum. Txhawm rau ua cov cib thiab cov vuas, yog tias qhov porosity siab dhau lawm, qhov kev tiv thaiv ntawm lub cev ntsuab tsis zoo, thiab cov mortar tsis yooj yim rau dai ntawm rab rawg yog tias nws qis dhau, yog li cov dej nqus dej feem ntau yuav tsum tau tswj xyuas. ntawm 5-15%. Cov xim ntawm lub cev ntsuab tom qab tua hluav taws yog txiav txim siab los ntawm cov ntsiab lus ntawm cov xim oxides hauv av nplaum thiab qhov hluav taws kub. Nws feem ntau yog daj lossis xim liab thaum raug rho tawm hauv cov nplaim hluav taws xob oxidizing, thiab xiav lossis dub thaum raug rho tawm hauv cov nplaim taws.
Cov cib xiav hauv kuv lub teb chaws cov khoom siv yog ua los ntawm cov av nplaum daj lossis xim liab uas muaj Fe₂O3 ua cov khoom siv raw. Lawv raug calcined nrog txo cov nplaim taws thaum tua hluav taws kom txo Fe203 rau FeO rau hauv cov xim xiav. Lub lauj kaub tais diav tuaj yeem muab faib ua cov tais diav zoo tib yam thiab cov tais diav zoo. . Ordinary pottery hais txog earthenware pots. Tank, tank, urns. Thiab refractory cib thiab lwm yam khoom nrog lub cev porous xim. Cov dej nqus dej ntawm cov tais diav zoo yog tseem 4-12%, yog li nws muaj permeability, tsis muaj translucency, feem ntau dawb, tab sis kuj muaj xim. Cov glaze feem ntau yog fusible glaze uas muaj txhuas thiab boron. Piv nrog stoneware, vim hais tias tus nqi ntawm flux tsawg dua thiab qhov kub ntawm qhov hluav taws kub tsis tshaj 1300 ° C, lub cev ntsuab tsis yog sintered tag nrho; piv nrog cov plooj (porcelain), cov kev xav tau ntawm cov khoom siv raw yog qis dua, cov yas ntawm qhov khoob yog ntau dua, thiab qhov kub thiab txias yog siab dua. Tsawg. Nws tsis yooj yim rau deform, yog li nws tuaj yeem yooj yim rau kev tsim, potting thiab lwm yam txheej txheem ntawm cov khoom. Tab sis lub zog txhua yam thiab kev cuam tshuam lub zog ntawm cov tais diav zoo zoo dua li cov plooj (porcelain). Lub pob zeb yuav tsum yog me me, thiab nws cov glaze yog softer dua glaze ntawm cov khoom saum toj no. Thaum nws cov txheej glaze puas lawm, lub cev ntxeem tau yooj yim stained, uas cuam tshuam rau kev nyiam huv.
Cov lauj kaub tais diav zoo tuaj yeem muab faib ua plaub hom raws li qhov muaj pes tsawg leeg ntawm lub cev: av nplaum, txiv qaub, feldspar, thiab clinker. Lub lauj kaub tais diav zoo yog ze rau lub lauj kaub tais diav. Txiv qaub-raws li cov tais diav zoo siv limestone li flux, thiab nws cov txheej txheem tsim khoom zoo ib yam li feldspar-based zoo pottery, tab sis qhov zoo tsis zoo li feldspar-raws li cov tais diav zoo. Vim tias nws tsis tshua muaj tsim nyob rau hauv xyoo tas los no, nws tau hloov los ntawm feldspar-raws li cov tais diav zoo. Feldspar fine pottery, tseem hu ua hard fine pottery, siv feldspar li flux. Nws yog qhov zoo tshaj plaws thiab dav siv hom pottery. Nyob rau lub sijhawm tsis ntev los no, ntau lub tebchaws tau siv cov khoom siv loj hauv txhua hnub (khob, phaj, thiab lwm yam) thiab cov tais diav huv huv los hloov cov plooj (porcelain kim). Cov khoom kub kub zoo cov tais diav yog ntxiv ib qho nyiaj ntawm clinker rau cov tais diav zoo, lub hom phiaj yog kom txo qis thiab tsis txhob pov tseg. Qhov zoo ntawm qhov khoob no feem ntau yog siv rau hauv cov khoom siv log tsheb loj thiab tuab (xws li da dej, tais tso quav, thiab lwm yam).
Stoneware hu ua" pob zeb porcelain" nyob rau hauv cov phau ntawv Suav thaum ub. Lub cev yog ntom thiab tag nrho sintered, uas yog heev ze rau porcelain. Txawm li cas los xij, nws tseem tsis tau vitrified, thiab tseem muaj qhov nqus dej tsawg dua 2%. Lub cev yog opaque thiab dawb, thiab feem ntau nws tso cai rau pom xim tom qab tua. Yog li ntawd, lub purity ntawm raw cov ntaub ntawv tsis yog siab npaum li cov plooj (porcelain), thiab cov ntaub ntawv raw yog yooj yim kom tau. Stoneware muaj lub zog siab thiab zoo thermal stability, yog qhov tsim nyog rau kev ntxhua khaub ncaws niaj hnub, thiab tuaj yeem ua kom yooj yim dhau qhov kub hloov pauv ntawm lub tub yees mus rau qhov cub. Hauv kev ua lag luam thoob ntiaj teb, vim yog kev txhim kho ntawm kev ncig xyuas thiab kev sib raug zoo ntawm cov khoom noj, Stoneware muaj qhov muag muag ntau dua li cov enamel.
Lub semi-porcelain dawb paug yog ze rau cov plooj (porcelain dawb paug), tab sis nws tseem muaj qhov nqus dej ntawm 3 mus rau 5% tom qab tua hluav taws (porcelain tiag tiag, qhov nqus dej yog qis dua 0.5%), yog li nws qhov kev ua tau zoo tsis zoo li porcelain. , tab sis zoo dua li cov ceramics zoo.
Porcelain yog theem siab dua hauv kev tsim cov ceramics. Nws cov yam ntxwv yog tias lub cev ntsuab tau ua tiav sintered thiab tag nrho vitrified, yog li nws yog tuab heev thiab tsis muaj permeability rau kua thiab gases. Qhov nyias nyias ntawm lub log yog semi-pob tshab, thiab cov hlaws yog lub plhaub-puab. Thaum koj yaim nws nrog koj tus nplaig, nws zoo nkaus li du thiab tsis nplaum. nyob. Hard porcelain muaj qhov ua tau zoo tshaj plaws ntawm cov ceramics.
