Lub ntab zog tau sawv los ntawm tsib fifties, nyob rau hauv Great Britain.The innovator txheej txheem, tsim los ntawm sir Alastair
Pilkington, raws li ua iav (los yog ua khob noom cookie), tseem tsis tau melted, floating rau molten tin.Then, gl -ass tau qhov kev ntshaus, nws txias thiab txiav.Nrhiav li cov iav ca, cov floats no zoo meej unif -tsev thiab muaj tsis muaj kev cuam tshuam.
Cov txheej txheem nplaum ntab dej yog tsim los ntawm Pilkington los ntawm 1952 thiab nws yog ib qho qauv thoob ntiaj teb rau kev ua khoom lag luam uas zoo tshaj plaws.
Cov khoom, uas yog originally produced 6mm thickness iav, tam sim no ua tau tsom-iav nrog thi -ckness uas heev ntawm 0,4e 25 hli.Qhov khoom siv yog sib xyaw nrog cov neeg thiab merged hauv ov -en.The iav merged mus txog li 1000 ℃, yog tsis tu ncua nyob hauv ib lub tank uas muaj kua hluavtaws, tshuaj tua kabmob ua ke.Kuv floats ntawm lub tin, kis nws tusyees.
Lub thickness yog tswj los ntawm cov kev ceev ntawm daim iav ntawv uas ua kom tiav raws li nws yuav ua kom tiav.Qhov -yawm ntiv taw (tswj kev txias), txheej txheem xaus nrog cov iav muaj polished thiab zoo tib yam
Feem ntau siv rau hauv tsev, tsheb, khoom siv hauv tsev thiab khoom rau kev dai kom zoo nkauj, cov nplaum ntoos yog cu -rrently suav tias yog dominants hauv lub khob iav thoob ntiaj teb.
