Chemical Strengthening: Lwm Txoj Kev Toughen iav

Yog hais tias tempering yog hais txog cua sov thiab huab cua, tshuaj ntxiv dag zog yog hais txog chemistry thiab ua siab ntev. Nws yog lub ntiaj teb sib txawv kiag li- qeeb dua, kim dua, thiab technically finicky. Tab sis thaum koj xav tau nyias, muaj zog, thiab distortion - iav dawb, tsis muaj qhov hloov pauv.

Nws ua haujlwm li cas

Lub hauv paus ntsiab lus yog ion pauv. Koj noj dej qab zib- txiv qaub los yog, feem ntau, aluminosilicate iav thiab submerge nws nyob rau hauv ib tug molten ntsev da dej-feem ntau poov tshuaj nitrate (KNO₃)- nyob ib ncig ntawm 400-450℃. Qhov ntawd yog qhov zoo hauv qab lub iav hloov pauv, yog li tsis muaj sagging, tsis muaj cov menyuam yoj, tsis muaj kev cuam tshuam.

Cov sodium ions nyob rau hauv lub iav saum npoo sib pauv qhov chaw nrog cov poov tshuaj ions loj dua los ntawm cov ntsev da dej. Cov poov tshuaj ions loj dua tau nkag mus rau hauv qhov chaw tsim los rau me me sodium ions. Lawv tsis haum. Qhov compression tsim ib txheej txheej saum npoo nyob rau hauv qhov kev ntxhov siab loj heev -feem ntau yog 50,000 txog 80,000 psi, siab tshaj qhov thermal tempering tuaj yeem ua tiav.

Qhov tob ntawm cov txheej no, hu ua "cov ntaub ntawv qhov tob" lossis DOL (qhov tob ntawm txheej), feem ntau yog 30 txog 80 microns. Nws yog nyias tab sis incredibly tawv.

Cov iav Matters

Koj tuaj yeem siv tshuaj ntxiv dag zog rau cov qauv dej qab zib- txiv qaub iav, tab sis cov txiaj ntsig tau zoo. Cov khawv koob tiag tiag tshwm sim nrogaluminosilicate iaviav. Cov ntsiab lus txhuas ua kom nrawm rau kev sib pauv ion thiab muab rau koj ob qho tib si saum npoo compression thiab cov ntaub ntawv sib sib zog nqus. Yog vim li cas koj lub xov tooj screen (Gorilla Glass, thiab lwm yam) yog aluminosilicate, tsis yog lub qhov rais iav.

Da dej: Chemistry yog txhua yam

Cov ntsev da dej tseem ciaj sia. Koj tsis yog sau lub tank nrog KNO₃ thiab hu nws ib hnub. Nws degrades raws sij hawm. Sodium tsim nyob rau hauv da dej, slows down tus nqi pauv. Yog tias sodium concentration siab dhau lawm, koj poob lub zog.

Cov neeg ua haujlwm tswj hwm qhov no nrog:

Ntxiv qeeb:tsis tu ncua pub tshiab KNO₃ kom dilute cov sodium

Da dej reconditioning:periodically dumping thiab hloov cov ntsev

Additives:Qee lub khw siv alumina los yog lwm yam sib txuas los nqus sodium thiab ua kom lub da dej ua haujlwm ntev dua

Ib chav da dej uas tsis saib xyuas ua rau iav uas zoo nkaus li zoo tab sis ua tsis tau qhov kev ntsuas khoov tsis tu ncua. Koj tsis tuaj yeem pom ntawm qhov muag liab qab.

Qhov Distortion Advantage

Qhov no yog vim li cas cov tshuaj muaj zog muaj zog. Thermal tempering muab rau koj yoj yoj, hneev, thiab anisotropy. Tshuaj ntxiv dag zog rau kojtsis muaj qhov ntawd. Lub khob yeej tsis mus saum nws qhov chaw mos. Nws tawm ntawm lub da dej raws nraim li nws mus rau hauv.

Yog tias koj ua:

Npog iav rau tso saib(kov panels, saib)

Nyias iav hauv qab 2 hliuas yuav warp nyob rau hauv ib tug tempering furnace

Cov duab tsis yooj yimnrog drilled qhov los yog cutouts uas yuav ntxhov siab - riser tawg nyob rau hauv ib tug quench

Tshuaj ntxiv dag zog yog tib lo lus teb.

Kev lag luam -Offs

Tshaj tawm.Ib txoj kab tempering cycles iav txhua ob peb feeb. Ib txoj kab uas muaj zog ntxiv rau hauv cov xuab moos -feem ntau yog 4 mus rau 12 teev ib batch, nyob ntawm seb hom iav thiab cov ntaub ntawv qhov tob xav tau. Koj tsis khiav siab ntim; koj khiav tus nqi siab.

Kev huv huv.Qhov no yog qhov uas feem ntau lub khw muag khoom. Lub khob yuav tsum tau phais kom huv si ua ntej mus rau hauv da dej. Txhua yam kab mob sib kis- ntiv tes, plua plav, seem polishing compound- tsim qhov "stop-tawm" qhov twg cov ion pauv tsis tuaj yeem tshwm sim. Qhov tshwm sim yog thaj chaw tsis muaj zog uas tshwm sim ua ke tom qab. Cov khw muag khoom zoo khiav chav huv huv rau kev thauj khoom.

tuav.Cov iav nkag mus rau hauv racks lossis pob tawb, feem ntau nrog cov ntug tiv thaiv. Koj tsis tuaj yeem cia cov khoom kov hauv da dej. Qhov twg lawv kov, qhov sib pauv ion tsis tshwm sim. Cov ntsiab lus tiv tauj no dhau los ua cov ntsiab lus tsis ua haujlwm.

Ncej -Ntseeg Warp.Qee lub sij hawm, cov iav nyias (hauv qab 1 hli) yuav tsim qhov hloov maj mam hloov tom qab ntxiv dag zog vim qhov tsis sib xws ion pauv ntawm ob qhov chaw. Nws yog mob taub hau. Kev kho yog ceev faj tswj ntawm immersion thiab rho tawm tus nqi, qee zaum nrog nitrogen tshuab kom sib npaug.

Kev kuaj thiab QC

Chemically reinforced iav tsis tawg rau hauv tsuav li tempered iav. Nws tseem yog iav kev nyab xeeb nyob rau hauv qhov kev txiav txim siab tias nws muaj zog dua, tab sis cov qauv tawg yog ze rau cov iav annealed. Qhov ntawd txhais tau hais tias kev xeem fragmentation tsis siv.

Hloov chaw, kev lag luam cia siab rau:

DOL (qhov tob ntawm txheej)ntsuas nrog lub ntsuas kev ntxhov siab saum npoo-feem ntau yog ib qho khoom siv tes uas siv prism coupling los nyeem cov nyhuv waveguide ntawm txheej compressed

Nto compression (CS)ntsuas los ntawm tib lub ntsuas -koj tab tom nrhiav qhov 50,000–80,000 psi ntau yam nyob ntawm daim ntawv thov

Nplhaib- ntawm- nplhaib lossis 4-point khoov kuajkom siv tau lub zog tiag tiag, tshwj xeeb tshaj yog rau hom iav tshiab lossis da dej

Txoj Kev Ua Lag Luam

Tshuaj muaj zog ntxiv tau tawg nyob rau hauv kaum tsib lub xyoos dhau los, uas tau tsav tag nrho los ntawm cov neeg siv khoom siv hluav taws xob. Txhua lub smartphone, ntsiav tshuaj, thiab smartwatch dhau los ntawm cov txheej txheem no. Tab sis cov ntawv thov kev tsim vaj tsev loj hlob dhau lawm- nyias nyias, lub teeb yuag iav rau sab hauv partitions, cov qhov rooj da dej uas nyias dua 6 hli tab sis tseem cuam tshuam - tiv taus, thiab cov qauv iav qhov pom qhov pom tseeb tseem ceeb dua li cov qauv tawg.

Qhov kev sib tw yog tus nqi. Cov ntsev yog kim. Cov da dej yuav tsum tau saib xyuas tas li. Lub voj voog lub sij hawm tua hla dhau. Thiab yog hais tias koj ntsia ib tug load ntawm pre-txiav, pre- polished cover iav rau ib tug xov tooj manufacturers, uas tsis yog ib tug seem nqi - yog kev sib tham txog seb koj nyob rau hauv daim ntawv teev cov neeg muag khoom.
