Quartz xuab zeb, limestone, feldspar, dej qab zib tshauv, boric acid, lead compounds, thiab antimony compounds yog txhua yam tau.
Qhov zoo ntawm cov iav fwj tuaj yeem ua raws li lub tebchaws cov qauv. Ib feem loj ntawm cov iav fwj siv rau cov khoom noj thiab dej haus. Cov kev cai rau cov iav fwj tsis yog tsuas yog cov yeeb yam xws li pom kev zoo, tab sis tseem thermal stability thiab tshuaj stability ntawm cov khoom. Vim hais tias cov iav fwj yuav tsum tau autoclaved ua ntej txhaws, nws yog kev nyuab siab hais tias cov khoom muaj thermal stability. Rau preservation ntawm pickles, fermented mis nyuj thiab lwm yam khoom, nyob rau hauv thiaj li yuav xyuas kom zoo, lub iav hwj yuav tsum muaj kev ruaj ntseg chemical tshuaj. Qhov zoo ntawm peb cov khoom iav yog tsis ncaj, thiab nws tsis yooj yim sua kom cov neeg siv kev soj ntsuam zoo rau txhua lub raj mis. Yog li, thiaj li yuav kom zoo, nws yog qhov pom zoo kom koj xaiv ib lub lag luam nrog kev lag luam zoo, xws li OI lub khob fais fab hauv Guangzhou, Shanghai, Wuhan thiab Tianjin, Suav, uas tuaj yeem ua tau raws li koj cov kev xav tau. Yuav tsis tas kos npe rau ib qho kev lav zoo, tshwj tsis yog nws tau teev nyob rau hauv daim ntawv cog lus.
Ntau yam ntaub ntawv rau kev npaj cov iav pob khoom ua ke tau sau ua ke ua cov ntaub ntawv raw rau khob. Nws muaj 7-12 hom, thiab muaj 4-6 hom ntaub ntawv tseem ceeb, xws li quartz xuab zeb, limestone, feldspar, soda tshauv, boric acid, hmoov txhuas, tiv thaiv compound, thiab lwm yam. Raws li lub luag haujlwm ntawm cov tswvcuab oxide nyob rau hauv lub iav qauv, nws muaj peev xwm yuav muab faib. Cov khoom siv raw ua cov oxide ntawm iav, cov khoom siv raw ntawm cov nqaij nruab nrab, thiab cov khoom siv raw ntawm cov sab nraud oxide tuaj yeem faib ua cov khoom raw ntawm cov kua qaub thiab oxid hlau oxide raws li xwm ntawm tus cob qhia oxide. Cov khoom batching yog raw cov khoom siv kom tau txais tej yam tseem ceeb ntawm cov iav thiab accelerating cov txheej txheem melting. Txawm hais tias kev siv tshuaj yog tsawg, cov nyhuv tseem ceeb heev. Cov khoom siv no tau muab faib rau cov neeg ua hauj lwm, cov neeg ua hauj lwm, cov neeg ua hauj lwm tha xim, cov neeg ua hauj lwm uas tsis sib haum, cov neeg sawv cev thiab cov neeg sawv cev oxidizing. , txo cov neeg ua hauj lawm, thiab lwm yam.
Cov khoom siv tib raw nrog cov formulations sib txawv, tib cov ntaub ntawv raw nrog lub hauv paus pib txawv thiab cov ntsiab lus ntawm cov ntsiab lus ntawm lwm yam yuav cuam tshuam cov khoom tsim thiab cov nqi tsim nqi. Nyob rau hauv cov ntaub ntawv ntawm ib tug me me disparity nyob rau hauv tus nqi ntawm raw cov ntaub ntawv, nws yog ib qhov nyuaj heev los ua ib qho tseem ceeb sib txawv nyob rau hauv sib piv ntawm lub iav fwj tsim, thiab qhov txawv yuav tsuas yog pom nyob rau hauv loj qhuav.
