Cov khob khob, nrog rau lawv cov pob tshab, kev huv, tsis muaj ntxhiab, thiab tsis yog - nqus cov khoom tsis zoo, tau dhau los ua cov khoom siv nyiam rau haus txhua hnub, tshuaj yej brewing, thiab kas fes. Txawm li cas los xij, kev ua lag luam muaj cov dazzling array ntawm khob khob, xws li tus nqi ntawm ob peb yuan mus rau pua pua yuan, nrog rau qhov sib txawv. Cov khob iav tsis zoo tuaj yeem ua rau muaj kev pheej hmoo xws li kev tawg tshwm sim los yog tso tawm cov khoom tsis zoo. Yog li ntawd, txhawm rau xaiv qhov muaj kev nyab xeeb, ruaj khov, thiab siab - khob khob zoo, ib qho yuav tsum xav txog ntau qhov ntev, nrog rau cov khoom siv thiab cov khoom siv tes ua.
Cov khoom siv yog qhov tseem ceeb hauv kev txiav txim siab qhov zoo ntawm lub khob khob; siab - cov ntaub ntawv zoo ua kom muaj kev nyab xeeb thiab kav ntev txij thaum pib. Tam sim no, cov khoom siv khob iav ntau tshaj plaws ntawm kev ua lag luam yog iav zoo tib yam, borosilicate iav, thiab iav siv lead ua. Ordinary iav tsis tshua muaj nqi tab sis muaj qis hardness, tsis txaus cua sov ua hauj lwm, thiab nws yog ib qho yooj yim mus tawg nyob rau hauv tam sim ntawd kub hloov. Nws kuj tseem muaj feem ntau lub teeb xa hluav taws xob tsawg, ua rau nws haum rau luv luv - siv txhua hnub tab sis tsis pom zoo rau tuav dej kub lossis dej kub. High borosilicate iav tam sim no yog lub ntsiab lus siab - cov khoom zoo. Nws muaj cov ntsiab lus boron siab, muaj zog thermal stability, thiab tuaj yeem tiv taus qhov kub thiab txias hloov ntawm -30℃txog 150 degree. Txawm tias thaum boiling dej yog poured rau hauv, nws tsis yooj yim tawg. Nws kuj muaj cov tshuaj lom neeg ruaj khov zoo, tsis muaj cov hlau hnyav hnyav, kev xa tawm lub teeb zoo heev, thiab qhov tseeb, tsis muaj qhov tsis huv -dawb iav phab ntsa, ua rau nws yog thawj qhov kev xaiv rau cov iav hauv tsev. Cov iav siv lead ua tau muab faib ntxiv rau hauv cov iav siv lead ua lead thiab lead- iav dawb crystal. Leaded crystal iav muaj qhov hnyav, siab refractive Performance index, thiab crystal{18}} pom tseeb, tab sis nws cov ntsiab lus txhuas ntau dhau tuaj yeem ua rau muaj kev phom sij rau kev noj qab haus huv thiab tau maj mam tawm mus. Lead{19}}dawb siv lead ua iav siv poov tshuaj{21}}calcium silicate es tsis txhob siv lead ua, khaws cov pob tshab ntawm cov iav siv lead ua thaum ua kom muaj kev nyab xeeb. Nws yog tsim rau cov neeg siv khoom uas nrhiav kev zoo nkauj zoo nkauj thiab zoo, tab sis tus nqi kuj yog siab heev.
Cov ntsiab lus ntawm cov txheej txheem tsim khoom ncaj qha cuam tshuam rau lub neej ntev thiab cov neeg siv kev paub ntawm cov iav. Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov txheej txheem molding, iav phab ntsa kho, thiab kev sib koom ua ke. Hais txog cov txheej txheem molding, siab -cov iav zoo feem ntau siv "tes- tshuab" lossis "tshuab- nias- tshuab" txheej txheem. Tes- blown iav muaj cov phab ntsa tuab tuab, tsis muaj qhov pom tseeb npuas lossis qhov tsis zoo, lub npoo du thiab sib npaug, thiab qhov zoo nkauj zoo nkauj. Tshuab- iav tshuab tshuab yog tsim los nrog kev ua haujlwm siab, cov lus qhia tshwj xeeb, thiab tus nqi pheej yig, nrog cov khoom zoo sib xws. Txawm li cas los xij, qee qhov qis dua - cov khoom lag luam tus nqi yuav muaj qhov tsis sib xws ntawm phab ntsa lossis burrs ntawm ntug. Thaum xaiv iav, tuav nws mus rau lub teeb rau kev tshuaj xyuas. Lub siab- iav zoo yuav muaj phab ntsa ntshiab yam tsis muaj npuas pom tseeb, impurities, lossis khawb. Yog tias phab ntsa muaj ntau npuas, tawg, los yog huab cua zoo li, nws qhia tau tias kev ua haujlwm tsis zoo thiab tsis zoo.
Kev kho ntawm cov iav phab ntsa thiab kev sib koom ua ke yog qhov tseem ceeb sib npaug. Lub siab- iav zoo muaj cov phab ntsa tuab zoo ib yam, muab kev tuav xis nyob thiab tiv thaiv kev tawg vim qhov tsis sib xws los ntawm qhov tsis sib xws. Lub npoo yog polished zoo, du, thiab burr -dawb, tiv thaiv kev txiav rau daim di ncauj thaum haus. Rau iav nrog cov tes tuav, xyuas tias qhov sib koom ua ke ntawm tus kov thiab lub cev muaj kev ruaj ntseg, tsis muaj xoob, qhov khoob, lossis cov kua nplaum ntau dhau. Lub iav ntawm qhov sib koom ua ke yuav tsum tsis muaj kab nrib pleb; txwv tsis pub, tus kov yuav tshem tawm thaum siv. Tsis tas li ntawd, thaum xaiv lub khob nrog lub hau, xyuam xim rau lub foob thiab cov khoom ntawm lub hau. Lub hau yuav tsum haum nruj rau lub ntug ntawm lub khob thiab tsis txhob xau thaum nchuav dej. Lub hau yuav tsum yog ua los ntawm cov khoom noj khoom haus - qib silicone, iav, lossis stainless hlau. Tsis txhob xaiv lub hau yas tsis zoo nrog cov ntxhiab tsw ntxhiab tsw zoo los tiv thaiv kev tso tawm cov khoom tsis zoo ntawm qhov kub thiab txias.
