Cov yam ntxwv tseem ceeb ntawm cov ntim ntim iav yog: tsis muaj tshuaj lom, tsis muaj ntxhiab; pob tshab, zoo nkauj, zoo barrier, airtight, ntau thiab ntau raw cov ntaub ntawv, uas tsis muaj nqi, thiab yuav siv tau ntau zaus. Thiab nws muaj qhov zoo ntawm kev tiv thaiv tshav kub, kev tiv thaiv siab thiab kev tu, thiab tuaj yeem ua kom tsis muaj menyuam ntawm qhov kub thiab txias thiab khaws cia ntawm qhov kub thiab txias. Nws yog qhov tseeb vim tias nws muaj ntau yam zoo uas nws tau dhau los ua cov khoom ntim khoom nyiam rau ntau yam dej haus xws li npias, txiv hmab txiv ntoo tshuaj yej, thiab kua txiv qaub jujube.
71% ntawm lub ntiaj teb npias yog ntim rau hauv iav npias fwj, thiab Tuam Tshoj kuj yog lub teb chaws muaj feem ntau ntawm cov iav npias fwj nyob rau hauv lub ntiaj teb no, accounting rau 55% ntawm lub ntiaj teb no lub iav npias fwj, ntau tshaj 50 billion ib xyoo. iav npias fwj yog siv ua npias ntim. Mainstream ntim, tom qab ib puas xyoo ntawm vicissitudes ntawm npias ntim, yog tseem nyiam los ntawm kev lag luam npias vim nws cov khoom ruaj khov, tsis muaj kuab paug, thiab tus nqi qis. Lub raj mis iav yog qhov nyiam ntim khoom thaum nws muaj qhov kov zoo tshaj plaws. Feem ntau, lub raj mis iav tseem yog cov ntim ib txwm rau cov tuam txhab npias. " Nws tau ua rau muaj txiaj ntsig zoo rau kev ntim npias, thiab ntau tus neeg nyiam siv nws.
Cov txheej txheem iav lub raj mis feem ntau suav nrog: ① raw khoom ua ntej. Cov ntaub ntawv nyoos ntau (quartz xuab zeb, dej qab zib tshauv, limestone, feldspar, thiab lwm yam) yog crushed, cov ntaub ntawv ntub dej qhuav, thiab cov khoom siv hlau uas muaj hlau yog raug tshem tawm cov hlau los xyuas kom zoo ntawm cov iav. ② Kev npaj cov khoom xyaw. ③ Melting. Cov iav batch yog rhuab ntawm qhov kub siab (1550 ~ 1600 degrees) nyob rau hauv lub pas dej ua ke kiln los yog pas dej ua ke rauv los ua ib tug uniform, npuas-dawb kua iav uas ua tau raws li qhov yuav tsum tau molding. ④ Pwm. Muab cov iav ua kua rau hauv pwm los ua cov khoom iav ntawm cov duab uas yuav tsum tau ua, xws li cov phaj tiaj tiaj, ntau yam tais diav, thiab lwm yam. ⑤ kev kho cua sov. Los ntawm annealing, quenching thiab lwm yam txheej txheem, qhov kev ntxhov siab, theem sib cais lossis crystallization hauv cov iav raug tshem tawm lossis tsim tawm, thiab cov txheej txheem ntawm lub khob hloov.

Qhov zoo ntawm cov iav ntim ntim hauv kev ntim khoom haus
iav fwj
iav fwj
Cov khoom ntim iav thiab cov thawv ntim khoom muaj ntau yam zoo: 1. Cov ntaub ntawv iav muaj cov khoom thaiv zoo, uas tuaj yeem tiv thaiv kev cuam tshuam ntawm cov pa oxygen thiab lwm yam gases rau cov ntsiab lus, thiab tuaj yeem tiv thaiv cov khoom tsis zoo ntawm cov ntsiab lus los ntawm volatilizing rau hauv qhov chaw;
2. Lub raj mis iav tuaj yeem siv tau ntau zaus, uas tuaj yeem txo cov nqi ntim khoom;
3. Cov iav tuaj yeem hloov xim thiab pob tshab;
4. Cov iav fwj muaj kev nyab xeeb thiab huv si, muaj kev tiv thaiv corrosion zoo thiab acid corrosion kuj, thiab tsim nyog rau ntim cov khoom siv acidic (xws li cov kua txiv hmab txiv ntoo, thiab lwm yam);
5. Tsis tas li ntawd, vim tias cov iav fwj tsim nyog rau kev tsim cov khoom siv tsis siv neeg puv cov kab ntau lawm, kev txhim kho cov iav tsis siv neeg lub raj mis filling tshuab thiab cov cuab yeej siv hauv Suav teb kuj tseem paub tab, thiab kev siv iav fwj los ntim cov txiv hmab txiv ntoo thiab cov kua txiv hmab txiv ntoo muaj tej yam khoom zoo hauv Suav teb.
