1, Siab borosilicate iav yog nyiam
Muaj cov iav uas tsis muaj cua sov thiab tsis kub-resistant iav ntawm lub khw.Kev siv kub ntawm cov iav uas tsis muaj cua sov yog feem ntau "-5 txog 70 ℃", thiab kev siv kub ntawm cov iav kub-resistant tuaj yeem yog 400 txog 500 degrees siab dua, thiab tuaj yeem tiv taus qhov kub ntawm qhov sib txawv ntawm "-30 txog 160". ℃".Raws li cov tshuaj yej ua + boiling cuab tam, kub resistant thiab lub teeb yuag siab borosilicate iav lauj kaub yog nyiam.
High borosilicate iav muaj qhov coefficient tsawg ntawm kev nthuav dav thiab yuav tsis tawg thaum muaj kev hloov pauv tam sim ntawd;kub tsis kam thiab acid kuj ua rau siab borosilicate tsis tshua muaj precipitate teeb meem tshuaj nyob rau hauv niaj hnub siv dej haus.
Qhov hnyav ntawm siab borosilicate iav tshuaj yej teeb yog ntau sib dua li "raws iav" uas muaj ntau cov hlau hnyav ions, thiab nws zoo li txawv ntawm cov iav zoo tib yam, pom nws tawm ntawm qhov nyuaj thiab nkig ntawm "raws iav".
Cov khoom zoo siab borosilicate iav thickness uniform, hnub ci yog pob tshab, cov nyhuv refractive yog qhov zoo, thiab lub suab ntawm khob nkig.
2, lub iav tsis yog qhov thicker qhov zoo dua
Cov khob khob tuab los tuav cov zaub mov txias yog qhov tsim nyog, cov khob haus dej kub nyias dua li tuab zoo.
Cov khob khob tuab vim yog cov txheej txheem, hauv kev tsim cov txheej txheem ntawm "kev kho annealing" (kom cov tshuaj yej teeb kub maj mam thiab poob qis, tshem tawm kev ntxhov siab) tsis zoo li tshuab khob khob nyias.Cov iav tuab tsis dissipate cua sov sai li cov iav nyias, thiab thaum cov dej kub npau npau rau hauv nws, sab hauv ntawm lub khob phab ntsa yog rhuab ua ntej thiab nthuav dav sai, tab sis sab nraud tsis nthuav ib txhij, yog li nws tawg.Nyias khob khob rau hauv dej npau npau, tshav kub sai sai, lub khob sib npaug synchronized expansion, nws tsis yooj yim rau tawg.
High borosilicate iav kuj feem ntau tsis ua kom tuab heev, vim tias ntau cov tshuaj yej teeb tuaj yeem ua kom sov los ntawm qhov qhib hluav taws, lub khob yog tuab heev, rwb thaiv tsev zoo dhau lawm, nws yuav tsis tuaj yeem ua si zoo ntawm qhov qhib hluav taws kub rwb thaiv tsev.Tsab ntawv Source.
Txawm li cas los xij, kev cuam tshuam kuj tseem yog qhov taw qhia tseem ceeb heev, koj tsis tuaj yeem hais tias koj tuaj yeem tiv taus qhov kub thiab txias txawm tias qhov cuam tshuam tsis zoo, cov iav nyias nyias kuj tseem tsis muaj zog.Yog li ntawd, lub thickness ntawm cov iav-resistant iav tshuaj yej teeb yog tsim tom qab kev txiav txim siab ntawm cov kws tshaj lij, nyias nyias los yog tuab heev tsis pom zoo rau kev yuav khoom.
Tsis tas li ntawd, feem ntau yuav tshwm sim nyob rau hauv ntau yam articulated qhov chaw ntawm kev ntxhov siab sab hauv tsis raug tshem tawm kuj yog ib qho laj thawj rau bursting.Hauv kev yuav khoom yuav tsum tau them sai sai rau tus kov, spout thiab lwm yam articulation yog du thiab ntuj.
3, qhov nruj ntawm lub hau yuav tsum tsim nyog
Thaum muas lub khob lauj kaub, xyuas qhov nruj ntawm lub hau thiab lub caj dab ntawm lub lauj kaub.Yog tias lub hau thiab lub caj dab xoob dhau lawm, lawv yuav yooj yim poob thaum koj siv lawv.Thiab yog hais tias nws haum kiag li, nws kuj yog ib qho yooj yim rau jam, thiab kuj yooj yim rau kev puas tsuaj.
Yog li ntawd, lub hau thiab lub cev ntawm lub khob lauj kaub yuav tsum tswj kom muaj qee qhov kev xoob, thiab qhov tseeb tias lub hau tsis nruj tsis tau txhais hais tias nws yog qhov tsis zoo.
Tsis tas li ntawd, iav teaware tsis yog lub thawv ntim uas muaj peev xwm tiv taus siab, yog tias lub hau nruj dhau thiab kaw dhau lawm, tom qab ntawd thaum kub sab hauv hloov pauv (txawm tias nws yog txias lossis cua sov los ntawm qhov qhib hluav taws), qhov cua yuav undergo thermal expansion thiab contraction, thiab qhov sib txawv ntawm huab cua tsis tuaj yeem sib npaug, tom qab ntawd tag nrho cov iav iav dhau los ua lub nkoj siab, thiab qhov tawg yuav tshwm sim yog tias lub siab tiv taus siab dhau.
Txawm hais tias lub hau tsis tuaj yeem npog nruj nreem tsis cuam tshuam rau kev siv ib txwm siv tshuaj yej teeb, tab sis kom ua tau raws li kev xav ntawm tib neeg tsis npog nruj tsis txhob txhawj, muaj ntau lub khob tshuaj yej teeb ntawm lub khw nrog lub hau. ua ke ntawm xyoob hau + sealing nplhaib, tsis yog ib qho kev xaiv zoo heev.
4, xyuam xim rau lub khob qhov ncauj lossis khob hauv qab ntawm lub pob me me
Cov pob no, hu ua "iav poob" hauv cov lus siv ntau lawm, yog ib qho ntawm cov khoom siv iav xuas tes ua tom qab ua tiav, txiav tawm qhov kawg ntawm cov iav ntau dhau, uas yog ib qho ntawm cov iav xuas tes ua ua ntej lub cub tawg.
Tawm ntawm qhov kaw ntawm lub qhov ncauj ntawm lub khob los yog lub lauj kaub tuaj yeem tiv thaiv qhov nqus ntawm cov iav thiab zam qhov xwm txheej tau piav qhia saum toj no uas cov cua kub siab hauv lub lauj kaub tsis tuaj yeem tso tawm thaum lub sijhawm cua sov, ua rau tawg.Txawm li cas los xij, rau qhov laj thawj zoo nkauj, muaj ntau lub khob tshuaj yej xuas tes ua uas txhob txwm tso cov iav tso rau hauv qab ntawm lub khob.
Qhov no yog qhov tshwm sim tshwj xeeb rau iav teaware siv kev lag luam centuries-laus ua ntej cub tawg txheej txheem, uas yog ib txwm muaj thiab muaj nyob rau hauv tag nrho cov tes-blown glassware, thiab yog ib qho tseem ceeb feature ntawm lub qhov muag liab qab kom paub qhov txawv handmade iav los ntawm mechanism glassware.
5 、 Tso cai rau cov khoom siv tes ua los yog cov npuas me me
Zoo iav teaware yog ua los ntawm cov ntaub ntawv ntshiab, xws li cov khoom tsis huv, lub khob yuav tsim cov kab, npuas, xuab zeb tsis zoo.Ripple, hais txog qhov chaw ntawm cov iav zoo li kab txaij;npuas, hais txog cov iav zoo li kab noj hniav me me;xuab zeb, hais txog iav tsis muaj molten dawb silica xuab zeb.Cov teeb meem no yuav cuam tshuam rau qhov nthuav dav coefficient ntawm iav, uas yuav yooj yim ua rau lub iav tawg, thiab tej zaum yuav tshwm sim vim qhov kub thiab txias thiab tsis siv neeg tshuab.
Tau kawg, tus naj npawb thiab qhov loj ntawm npuas yog qhov kev xav ntawm qhov zoo, tab sis qhov tshwm sim ntawm kev tsim "tsis muaj phau ntawv qhia tsis muaj npuas me" nyob rau hauv qhov chaw ua haujlwm kub kub yuav luag xoom, thiab txawm tias cov tshuaj yej kub-resistant tshaj plaws. cov teeb yuav muaj qhov xwm txheej zoo ib yam.Txawm li cas los xij, tsuav nws tsis cuam tshuam rau kev zoo nkauj thiab kev siv, peb yuav tsum tso cai rau qee qhov kev qhia uas tsis tuaj yeem zam tau thiab muaj npuas me me.
