Keeb Kwm Ntawm Tempered Glass Development

Kev txhim kho ntawm cov iav tempered tuaj yeem taug qab mus rau nruab nrab -17 xyoo pua. Ib tug tub huabtais ntawm Rhineland hu ua Robert ib zaug ua ib qho kev sim siab. Nws muab ib lub khob molten tso rau hauv dej txias thiab ua ib lub khob uas tawv heev. Lub khob iav muaj zog no zoo li cov dej poob nrog tus Tsov tus tw ntev thiab nkhaus, hu ua "Prince Robert's granules". Tab sis thaum tus Tsov tus tw ntawm cov granule yog khoov thiab tawg, tag nrho cov granule dheev tsoo hnyav thiab txawm hloov mus ua hmoov zoo. Cov txheej txheem saum toj no zoo ib yam li quenching ntawm hlau, tab sis qhov no yog quenching ntawm iav. Qhov quenching no tsis ua rau muaj kev hloov pauv ntawm cov iav, yog li nws tseem hu ua lub cev quenching (lub cev tempered), yog li tempered iav hu ua tempered iav (tempered iav).
Thawj patent rau iav tempering tau txais los ntawm Fabkis nyob rau hauv 1874. Txoj kev tempering yog kom sov lub iav mus rau ib tug kub nyob rau hauv lub softening kub thiab tam sim ntawd muab tso rau hauv ib tug kuj tsis tshua muaj kub kua tank ua rau kom lub saum npoo ntawm kev nyuaj siab. Txoj kev no yog txoj kev ua kua thaum ntxov. Frederick Siemens ntawm lub teb chaws Yelemees tau txais patent nyob rau hauv 1875, thiab George E. Rogens ntawm Massachusetts, USA, tau siv txoj kev tempering rau iav wine iav thiab teeb ncej hauv 1876. Nyob rau tib lub xyoo, Hugh O'heill ntawm New Jersey tau txais patent.
Nyob rau xyoo 1930, Saint-Gobain ntawm Fabkis, Triplex ntawm Tebchaws Meskas, thiab Pilkington ntawm Tebchaws Askiv txhua tus tau pib tsim cov iav loj loj rau lub tsheb cua. Nyiv kuj tau ua tiav kev lag luam ntawm cov iav tempered hauv xyoo 1930s. Txij thaum ntawd los, lub ntiaj teb pib lub sijhawm ntawm kev tsim cov iav tempered loj.
Tom qab xyoo 1970, Triplex ntawm United Kingdom tau ua tiav hauv tempering iav nrog lub thickness ntawm 0.75 ~ 1.5mm nrog kua nruab nrab, xaus cov keeb kwm uas lub cev tempering yuav tsis temper nyias iav. Qhov no yog ib qho kev ua txhaum loj hauv tempered iav technology.
Lub keeb kwm ntawm tempered iav nyob rau hauv Tuam Tshoj pib nyob rau hauv 1955, thaum Shanghai Yaohua iav Hoobkas pib sim ntau lawm, thiab Qinhuangdao Tempered iav Hoobkas ua tau zoo nyob rau hauv sim ntau lawm nyob rau hauv 1958. Nyob rau hauv 1965, Qinhuangdao Yaohua iav Hoobkas pib tsim tub rog tempered iav. Nyob rau xyoo 1970, Luoyang Glass Factory yog thawj zaug qhia Belgian tempering khoom. Tib lub sijhawm, Shenyang Glass Factory muab tshuaj tempered iav rau hauv ntau lawm.
Txij li thaum xyoo 1970s, tempered iav tshuab tau txhawb nqa thiab nrov thoob ntiaj teb. Tempered iav tau pib siv rau hauv kev lag luam tsheb, kev tsim kho, aviation, electronics, thiab lwm yam, tshwj xeeb tshaj yog nyob rau hauv kev tsim kho thiab tsheb.
