Los ntawm cov txheej txheem cua sov thiab kev kho cua txias sai, ua kom cov iav nto muaj lub siab thiab kev ntxhov siab, thiab sab hauv muaj kev ntxhov siab tensile, tom qab ntawd coj tau zoo dua thiab muaj zog ntau dua rau lub khob.Nws zoo li ntawd, ob sab ntawm cov iav uas muaj zog cua sov yog zoo li lub caij nplooj ntoos hlav net uas ntsws mus rau nruab nrab, tab sis cov txheej nruab nrab ntawm sab hauv yog zoo li lub caij nplooj ntoos hlav uas nthuav mus rau sab nraud.Thaum lub iav tempered yog dabtsi yog khoov, lub caij nplooj ntoos hlav net ntawm sab nrauv yuav ncab, ces cov iav yuav khoov rau hauv ib tug loj radian tsis tawg, qhov no yog lub hauv paus ntawm toughness thiab lub zog.Yog tias qee qhov laj thawj tshwj xeeb rhuav tshem lub caij nplooj ntoo hlav nrog lub zog tensile sib npaug thiab rub lub zog, lub iav tempered yuav tawg mus rau hauv cov khoom tawg.
Cov iav tempered tau ua raws li cov yam ntxwv,
Ua ntej, kev ruaj ntseg zoo.Lub zog ntawm lub iav tempered yog 3 ~ 4 npaug loj dua li cov ntab iav, lub tiaj tus duab yuav tawg mus rau hauv cov khoom me me, kom txo qis qhov kev puas tsuaj uas yog vim tias cov tawg tawg poob los yog txaws, ces cov iav toughened belongs rau iav kev nyab xeeb. .
Thib ob,zoo thermal stability.Cov iav tempered muaj qhov ntsuas kub zoo, txawm tias muaj qhov sib txawv ntawm 200 ℃ ntawm ib daim iav tempered, nws yuav tsis tawg vim qhov kub sib txawv.
Peb,muaj spontaneous tawg nyob rau hauv lub tempered iav.Tempered iav panels tej zaum yuav tawg txawm tias nws yog khaws cia lawm.Thiab qhov flatness ntawm tempered iav tsis zoo li cov iav uas tsis yog tempered.
Semi-tempered iav yog nruab nrab ntawm cov iav ntab iav thiab iav tempered, nws lub zog yog 2 npaug loj dua li cov iav uas tsis yog tempered, qhov loj ntawm cov tawg tawg kuj loj dua iav tempered, ces nws tsis yog iav kev nyab xeeb.Qhov tsis zoo ntawm lub iav semi-tempered tom qab tawg yuav tsis hla, tab sis thaum ntsia lub semi-tempered iav nrog clamp los yog thav duab, txhua qhov tawg yuav raug kho los ntawm cov npoo, yuav tsis poob los yog khawb tib neeg, ces lub semi- tempered iav muaj ib qho kev ruaj ntseg.
Lub thermal stability ntawm lub iav semi-tempered tsis muaj zog dua tempered iav, nws yuav tsis tawg nrog qhov kub thiab txias sib txawv mus txog 100 ℃ ntawm ib daim iav semi-tempered.Tab sis qhov zoo tshaj plaws ntawm cov iav semi-tempered yog tsis muaj qhov tawg tawg.Thiab lub flatness rau lub tshav kub muaj zog iav yog zoo dua tempered iav.
Thov nco ntsoov tias, cov iav tuab yog thinner dua 8 hli tuaj yeem ua rau iav semi-tempered.Yog hais tias lub thickness yog tuab dua 10 hli, nws yog ib qho nyuaj rau ua rau hauv semi-tempered iav.Txawm tias lub thickness loj dua 10 hli tuaj yeem kho cua sov hauv cov iav tempering rauv, thaum muab nws tawm, tej zaum nws tsis yog iav ntab lossis iav semi-tempered, lossis tsis tuaj yeem ua tau raws li cov qauv iav.
