26 Sib tham txog qhov tshwm sim ntawm qhov tsis tsim nyog pib tsim ntawm Vial iav fwj

Cov iav vials feem ntau yog siv los ua cov thawv ntim tshuaj vim lawv cov tshuaj lom neeg ruaj khov. Txawm li cas los xij, ntau tus neeg tsis nkag siab txog cov txheej txheem tsim khoom ntawm iav vials thiab nyiam tsis quav ntsej txog qhov muaj peev xwm txaus ntshai. Txhawm rau kom muaj kev nyab xeeb thiab kev ua tau zoo ntawm cov tshuaj, nws yog ib qho tseem ceeb kom nkag siab txog cov txheej txheem tsim cov iav vials thiab qhov ua rau muaj kev cuam tshuam tsis zoo ntawm cov qauv tsim tsis tsim nyog.

Ua ntej, tsim thiab tsim cov pwm yuav tsum ua kom tiav. Thawj cov khoom siv raw rau iav yog quartz xuab zeb, uas, nrog rau lwm cov ntaub ntawv pabcuam, yog melted rau hauv lub xeev ua kua ntawm qhov kub thiab txias. Cov iav molten no ces txhaj rau hauv pwm, txias, txiav, thiab tempered los ua lub vial iav fwj.

Cov txheej txheem batching ntawm vial iav fwj, los ntawm cov khoom siv raw mus rau cov khoom tiav, ua raws li qhov kev txiav txim ua ntej. Ntau yam raw khoom yog hnyav thiab ces sib tov uniformly nyob rau hauv ib tug tov khoom. Cov ntaub ntawv tseem ceeb rau iav muaj xws li quartz xuab zeb, limestone, feldspar, dej qab zib tshauv, thiab boric acid.

Txheej txheem melting:

Melting suav nrog cua sov cov khoom siv raw ntawm qhov kub thiab txias los tsim cov iav tsis muaj npuas, tsis muaj npuas. Qhov no yog ib txoj kev nyuaj uas muaj ob qho tib si lub cev thiab tshuaj. Lub melting ntawm iav yuav siv qhov chaw nyob rau hauv lub tank rauv, qhov twg cov iav batch yog melted nyob rau hauv lub cub tawg tank, nrog ib tug qhib nplaim hluav taws kub rau sab saum toj ntawm lub iav yaj. Lub melting kub ntawm iav feem ntau yog li ntawm 1300 degree mus rau 1600 degree. Feem ntau cov furnaces siv nplaim hluav taws kub, thaum ob peb siv hluav taws xob cua sov, hu ua hluav taws xob furnaces. Niaj hnub no, lub tank furnaces ua haujlwm tsis tu ncua.

Vial iav fwj yog tsim los ntawm kev sib xyaw ntawm ntau cov ntaub ntawv raw, suav nrog cullet (recycled glass), soda tshauv, barium carbonate, thiab quartz xuab zeb. Cov ntaub ntawv no yog melted thiab zoo li tus ntawm qhov kub ntawm 1600 degree, ua rau lub thawv uas tuaj yeem tsim tau ntau yam duab raws li cov pwm sib txawv.
