Iav fwj mis ntau lawm yuav muaj ntau cov kauj ruam -los ntawm kev tsim cov pwm kom tsim cov iav molten rau hauv qhov zooCov. Cov kws txawj ntse siv cov tshuab tshwj xeeb thiab cov tswv yim tsis zoo los hloov cov ntaub ntawv raw rau hauv cov iav iav pristine.
Nws pib nrog cov khoom xyaw.Thawj Cheebtsam ntawm iav yog silicon dioxide (xuab zeb), sodium carbonate (dej qab zib carbonate (sida tshauv), thiab calcium oxide (limestone). Cov zaub mov ntxiv tau sib xyaw ua kom zoo dua cov khoom zoo li kev pom zoo, lub zog, thiab xim. Cov ntaub ntawv raw yog ntsuas kom meej thiab sib xyaw ua ke rau hauv pob ua ntej tau thauj mus rau hauv qhov cub.
Sab hauv qhov cub, kub txog 2500 ° F kom yaj qhov sib xyaw kom sib xyaw ua kua.Kev impurities raug tshem tawm thiab lub khob siv rau ntawm ib qho kev sib xws. Lub iav molten ntws raws cov kev cai lij choj sib sau ua ke rau hauv kev ua yeeb yam uas nws tau ua ua ntej nkag mus rau cov tshuab ua ntej.
Tshuab lub raj mis muaj xws li tshuab-thiab tshuab, nias-thiab-tshuab, thiab-tshuab.Hauv lub tshuab-thiab-tshuab, ib qho gog ntawm iav yog poob rau hauv cov pwm tsis sib xws thiab inflated los ntawm cov cua compressed los ntawm lub tshuab pa.
Cov parison siv duab tiv thaiv cov phab ntsa ntawm cov pwm ua ntej hloov mus rau qhov kawg pwm rau kev yooj yim dua kom txog thaum nws conforms precisely.
Rau xovxwm-thiab-tshuab, cov parison yog tsim los ntawm nias lub khob gob rau hauv cov pwm tsis sib xws dua li tshuab cua. Cov neeg parons ua ib nrab yog mus los ntawm qhov kawg tshuab pwm. Nqaim caj dab xovxwm-thiab-tshuab tsuas yog siv cua siab los ua lub caj dab tiav. Lub cev yog puab los ntawm nias.
Thaum tso tawm ntawm cov pwm, cov iav fwj tawg ua kom tshem tawm cov kev ntxhov siab thiab tiv thaiv tawg.Annealing ncu gratuallyua kom txiaslawv dhau sijhawm lossis hnub. Cov khoom siv tshuaj xyuas cov tshev rau qhov tsis xws luag nyob rau hauv cov duab, kab nrib pleb, ntsaws ruaj ruaj thiab sab hauv siab kuj. Pom zoo fwj yog ntim thiab xa mus rau fillers.
Txawm hais tias tswj nruj, tswjfwm tsis tau zoo tseem tshwm sim thaum lub sijhawm cov iav ntau lawm.Cov pob zeb tsis xws luag tshwm sim thaum cov khoom ntawm refractory refractory tawg tawm ntawm kiln phab ntsa thiab sib tov nrog lub khob. Noob yog me me npuas ntawm unmelted batch. Ream yog iav tsim hauv pwm. Whiting tshwm li milky ua plob ntawm theem sib cais. Qaum thiab cov quav nyab yog cov quav kab cim cov ntws ntawm iav mus rau hauv parison.
Lwm qhov flaws muaj xws li faib, quav, wrinkles, doog, thiab cov tshev uas ua rau pwm teeb meem, kev tuav dej kub. Hauv qab qhov tsis xws luag zoo li sagging thiab thinning tuaj yeem tshwm sim thaum muaj kev txhawb nqa.
Cov fildect fwj yog culled los tiv thaiv cov teeb meem zoo hauv qab kab. Cov kev soj ntsuam dhau los mus kho kom zoo nkauj los ntawm kev tshuaj ntsuam luam ntawv, cov nplaum nplaum lossis cov khoom sib npaug ua ntej tau sau.
Los ntawm cov khoom siv raw rau cov khoom tiav, lub raj mis iav ua haujlwm cuam tshuam nrog kev kawm tiav qib, cov cuab yeej tshwj xeeb, thiab kev tswjhwm zoo. Lub intricate seev cev ntawm tshav kub, siab thiab tsa suab yields tsheej lab ntawm flawless iav nkoj txhua hnub. Nws yog Marvel yuav ua li cas xws li kev zoo nkauj tawm los ntawm hluav taws thiab xuab zeb.
