Npog iav Deep Dive: Ion pauv vs. thermal tempering - vim li cas ib tug yeej
Apr 02, 2026
Tsis yog tag nrho cov iav npog yog tsim sib npaug. Qhov sib txawv tiag tiag nyob hauv iav, tsis yog ntawm daim ntawv spec. Cia peb rhuav tshem ob txoj hauv kev ntxiv dag zog thiab vim li cas kev lag luam xaiv tus yeej meej.
Thermal tempering (txoj kev qub)
Tshav kub lub khob kom ze rau nws qhov muag muag (kwv yees li 650℃rau dej qab zib- txiv qaub iav), ces nplawm nws nrog cua txias. Qhov saum npoo txias thiab shrinks sai. Sab hauv txias qeeb qeeb. Qhov kev tsis sib haum ntawd tsim kom muaj qhov chaw compression. Yooj yim thiab pheej yig.
Tab sis thermal tempering muaj ib qho kev txwv nyuaj: nws NW nyuam qhuav ua haujlwm ntawm iav thinner dua 2 hli. Hauv qab no, qhov kub gradient tsis tuaj yeem tsim kev ntxhov siab txaus. Tias yog vim li cas koj lub tsheb sab qhov rais (nyob ib ncig ntawm 3-4mm) yog thermally tempered. Koj lub xov tooj screen (0.5-0.7mm) tsis yog.
Ion pauv (tus yeej)
Qhov no yog cov txheej txheem tshuaj. Submerge lub khob hauv ib da dej kub ntsev (feem ntau molten potassium nitrate ntawm 380-450 degree). Cov sodium ions me me nyob ze ntawm iav qhov chaw sib pauv nrog cov poov tshuaj ions loj dua los ntawm cov ntsev da dej. Cov ions loj dua nyob rau hauv thiab thawb tawm tsam ib leeg. Uas tsim ib txheej compressed.
Cov khawv koob? Nws ua haujlwm ntawm iav li nyias li 0.3mm. Corning's Gorilla Glass siv qhov no. Zoo li SCHOTT's Xensation thiab AGC's Dragontrail. Cov txheej txheej compression qhov tob tuaj yeem hloov kho los ntawm 20 mus rau 150 microns nyob ntawm seb lub sijhawm so thiab kub.
Ua cas tsis yog ob leeg?
Qee tus neeg suav npog iav tau sim cov txheej txheem hybrid hauv 2024-2025. Lub tswv yim: thermal temper ua ntej, ces ion pauv. Hauv kev xav, koj tau txais ob txheej ntawm compression. Hauv kev xyaum, cov kauj ruam thermal qhia txog micro- tawg uas tom qab da dej ntsev dhau los ua kev puas tsuaj loj. Yield poob qis dua 50%. Tsis muaj leej twg ua qhov kev lag luam niaj hnub no.
Dab tsi pros saib rau:
CS (Compressive Stress): Ntsuas hauv MPa. Siab dua yog qhov zoo dua rau kev poob qis. Feem ntau: 600-900 MPa rau ion- pauv aluminosilicate.
DOL (Qhov tob ntawm txheej): Yuav ua li cas sib sib zog nqus compression mus. Sib sib zog nqus yog zoo dua rau khawb kuj. Cov iav nyias xav tau DOL qis dua 50 microns lossis nws tau nkig.
CT (Central Tension): Tus zais. Siab dhau lawm thiab iav tawg ntho. Txhua lub npog iav engineer paub tus lej no tab sis tsis tshua tham txog nws.
Khoom plig rau cov neeg yuav khoom:
Yog tias koj qhov chaw yog ntau dua 2 hli tuab, thermally tempered soda- txiv qaub iav yog qhov zoo thiab pheej yig. Yog tias koj tab tom tsim txhua yam nyias, nqa tau, lossis nkhaus, koj xav tau ion pauv. Tsis muaj shortcut.
