Nkag siab Tempered Glass Spontaneous Breakage thiab qhov tseem ceeb ntawm kev kho cua sov soak

Tempered iav, tseem hu ua toughened iav, yog ib qho kev xaiv nrov rau ntau yam kev siv vim nws lub zog thiab kev nyab xeeb nta. Txawm li cas los xij, ib qho kev txhawj xeeb tseem ceeb nrog cov iav tempered yog nws txoj kev nyiam ua rau muaj kev tawg, feem ntau hu ua "tus kheej tawg." Kab lus no yuav tshawb txog cov laj thawj tom qab qhov tshwm sim no, yuav ua li cas tiv thaiv nws, thiab lub luag haujlwm tseem ceeb ntawm kev kho cua sov so kom ntseeg tau qhov kev ntseeg siab ntawm cov khoom iav tempered.

Tempered Glass yog dab tsi?
Tempered iav yog tsim los ntawm cov txheej txheem ntawm huab cua kub thiab txias ceev, ua rau nws muaj zog ntau dua li cov iav txheem. Cov txheej txheem no tsis tsuas yog nce nws lub zog tab sis kuj ua rau nws tawg mus rau hauv me me, blunt pieces es tsis txhob ntse shards thaum tawg, txhim khu kev ruaj ntseg. Tempered iav yog dav siv nyob rau hauv daim ntaub ntawv xws li da dej qhov rooj, iav qhov rooj, facades, thiab automotive qhov rais.

Lub Phenomenon ntawm Spontaneous Breakage
Txawm hais tias nws lub zog muaj zog, tempered iav tuaj yeem tawg qee zaus yam tsis muaj qhov tshwm sim sab nraud. Qhov no spontaneous breakage tuaj yeem raug ntaus nqi rau ntau yam:

1. Nickel Sulfide suav nrog
Ib qho ntawm cov laj thawj tseem ceeb ntawm kev tawg ntawm cov iav tempered yog qhov muaj cov nickel sulfide (NiS) suav nrog. Cov microscopic impurities tuaj yeem nyob twj ywm tsis pom thaum lub sijhawm tsim khoom. Thaum cov iav tempered raug kub hloov pauv, cov kev suav no tuaj yeem nthuav dav thiab cog lus ntawm tus nqi sib txawv dua li cov iav ib puag ncig, ua rau muaj kev ntxhov siab sab hauv. Nyob rau tib lub sijhawm, qhov kev ntxhov siab no tuaj yeem ua rau muaj kev tawg sai sai.

2. Thermal Stress
Kev ntxhov siab thermal tshwm sim thaum muaj qhov sib txawv ntawm qhov kub thiab txias thoob plaws ntawm lub khob. Piv txwv li, yog tias ib sab ntawm lub iav vaj huam sib luag raug tshav ntuj thaum lwm qhov tseem nyob ntxoov ntxoo, qhov no tuaj yeem tsim kev ntxhov siab uas yuav ua rau tawg. Lub peev xwm ntawm tempered iav los tiv thaiv thermal kev ntxhov siab yog txhim kho los ntawm cov txheej txheem tempering, tab sis cov xwm txheej huab cua tseem tuaj yeem ua rau tsis ua haujlwm.

3. Mechanical Impact
Txawm tias muaj kev cuam tshuam me me ntawm cov iav tempered tuaj yeem ua rau tawg, tshwj xeeb tshaj yog tias cov iav muaj kev ntxhov siab los yog kev cuam tshuam. Qhov no tuaj yeem tshwm sim thaum lub sijhawm teeb tsa, kev saib xyuas, lossis txawm tias thaum siv tas li.

Tiv thaiv kom tsis txhob tawg
Txhawm rau txo qhov kev pheej hmoo ntawm kev tawg ntawm cov iav tempered, ob peb qhov kev ceev faj tuaj yeem ua tau:

1. Kev Tswj Xyuas Zoo hauv Kev Tsim Khoom
Cov neeg tsim khoom yuav tsum siv cov txheej txheem tswj xyuas kom zoo txhawm rau txheeb xyuas thiab tshem tawm cov nickel sulfide suav nrog thaum tsim khoom. Cov kev sim siab tshaj plaws, zoo li X-ray thiab kuaj ultrasonic, tuaj yeem pab txheeb xyuas cov teeb meem suav nrog ua ntej lub iav mus txog lub khw.

2. Cov txheej txheem kev teeb tsa kom raug
Xyuas kom meej tias tempered iav raug ntsia kom raug yog qhov tseem ceeb. Qhov no suav nrog kev siv cov khoom siv txhim kho kom tsim nyog, zam kev siab dhau ntawm cov npoo, thiab xyuas kom meej tias lub iav tsis raug cuam tshuam rau lub sijhawm teeb tsa.

3. Kev tu tsis tu ncua
Kev tshuaj xyuas tsis tu ncua tuaj yeem pab txheeb xyuas cov teeb meem muaj peev xwm, xws li cov kab nrib pleb lossis chips, ua ntej lawv ua rau muaj kev tawg. Kev tuav lub khob thiab nws cov khoom siv mounting tuaj yeem tiv thaiv kev ntxhov siab ntawm lub khob.

4. Zam kev hloov pauv kub heev
Kev txo qis ntawm qhov kub thiab txias hloov pauv tuaj yeem pab txo qhov kev pheej hmoo ntawm thermal stress. Qhov no yuav suav nrog kev siv ntxoov ntxoo lossis awnings los tiv thaiv iav panels los ntawm kev tshav ntuj ncaj qha los yog ua kom muaj cua txaus hauv qhov chaw uas siv iav tempered.

Lub luag haujlwm ntawm Kev Kho Hniav Soak
Ib txoj hauv kev zoo tshaj plaws los txo qhov kev pheej hmoo ntawm kev tawg ntawm cov iav tempered yog kev kho cua sov so. Cov txheej txheem no suav nrog cov iav tempered rau cov txheej txheem cua sov tswj tom qab nws tau tsim. Nov yog nws ua haujlwm li cas:

1. Txheej txheem txheej txheem
Thaum tshav kub kub kev kho mob, lub iav tempered yog muab tso rau hauv ib lub qhov cub thiab rhuab mus rau ib tug tshwj xeeb kub-feem ntau nyob ib ncig ntawm 290 degree (554 degree F) - thiab khaws cia ntawm qhov kub thiab txias rau lub sij hawm predetermined. Cov txheej txheem no yuav pab txhawm rau txhawm rau nthuav dav ntawm cov nickel sulfide inclusions uas tej zaum yuav muaj.

2. Kev txheeb xyuas cov iav tsis raug
Los ntawm cua sov lub khob, txhua qhov kev suav nrog uas tuaj yeem ua rau muaj kev tawg ntawm lub cev yuav nthuav dav thiab ua rau lub khob tawg thaum kho. Qhov no tso cai rau cov tuam txhab lag luam txheeb xyuas thiab muab pov tseg cov iav tsis zoo ua ntej nws raug teeb tsa hauv cov tsev lossis cov khoom lag luam.

3. Txhim kho kev nyab xeeb
Kev kho cua sov so kom zoo txhim kho kev nyab xeeb ntawm cov khoom siv iav tempered. Los ntawm kev tshem tawm cov kev pheej hmoo uas tshwm sim los ntawm nickel sulfide inclusions, qhov tshwm sim ntawm kev tawg tshwm sim yog txo qis. Cov txheej txheem ntxiv ntawm kev ntseeg siab no yog qhov tseem ceeb tshwj xeeb hauv cov chaw tsheb loj, kev teeb tsa iav loj, thiab kev siv kev nyab xeeb-tseem ceeb.

4. Cov qauv kev lag luam
Ntau cov cai hauv tsev thiab cov qauv kev nyab xeeb tam sim no pom zoo los yog xav tau kev kho cua sov so rau cov iav tempered siv hauv qee yam kev siv. Kev ua raws li cov qauv no yuav pab xyuas kom meej tias cov iav tuaj yeem tiv taus ib puag ncig kev ntxhov siab thiab txo kev lav phib xaub rau cov tuam txhab thiab cov neeg tsim khoom.

Xaus
Thaum cov iav tempered yog cov khoom siv muaj zog thiab muaj ntau yam, nws qhov kev cuam tshuam rau kev tawg tsis tu ncua tseem muaj kev txhawj xeeb. Nkag siab txog qhov ua rau ntawm qhov tshwm sim no thiab siv cov kev tiv thaiv kev tiv thaiv-xws li kev tswj kom zoo, kev teeb tsa kom raug, thiab kev saib xyuas tsis tu ncua- tuaj yeem txo qhov kev pheej hmoo ntawm kev tawg.

Ntxiv mus, kev kho cua sov so yog ib qho tseem ceeb ntawm cov txheej txheem uas txhim kho kev nyab xeeb thiab kev ntseeg siab ntawm cov khoom iav tempered. Los ntawm kev txheeb xyuas thiab tshem tawm qhov tsis xws luag ua ntej kev teeb tsa, kev kho cua sov so ua lub luag haujlwm tseem ceeb hauv kev ua kom cov iav tempered tuaj yeem siv yam xyuam xim rau ntau yam kev siv. Raws li qhov kev thov rau cov iav ua haujlwm siab txuas ntxiv zuj zus, qhov tseem ceeb ntawm cov kev tiv thaiv thiab kev kho mob no tsis tuaj yeem hais dhau los.
