Muaj ob hom iav ntaub ntawv: kub tsis kam thiab kub tsis kam.Tsis yog-siab kub resistant iav kub yog feem ntau "-5 mus rau 70 degrees Celsius", yog hais tias nws yog ua los ntawm high borosilicate cov ntaub ntawv, ces nws siv kub yuav ua tau 400 mus rau 500 degrees siab dua, thiab muaj peev xwm tiv taus lub instant "-30 mus rau 160 degrees. Celsius” kub txawv.
Qhov sib txawv ntawm lub khob thiab cov khoom siv cua sov yog qhov yooj yim heev: Lub khob kub-resistant nrog dej kub ntawm nws qhov chaw tsis kub, thiab cov iav uas tsis muaj cua sov nrog dej kub ntawm nws qhov chaw yog kub.Tom qab paub qhov txawv ntawm qhov ntsuas kub ntawm ob hom iav no, cia peb saib cov yam ntxwv ntawm ob hom iav no.
Qhov kev pabcuam kub ntawm lub khob ib txwm muaj
Cov khoom siv zoo tib yam iav yog cov khoom siv hluav taws xob tsis zoo ntawm cov cua sov, raws li ib feem ntawm cov iav phab ntsa dheev ntsib cua sov (lossis txias), txheej txheej ntawm lub khob yog rhuab tsawg dua kev nthuav dav tab sis cov cua sov sab nraud txaus, ua rau cov iav kub sib txawv ntawm cov khoom yog loj dua, thiab vim yog vim li cas ntawm cov cua sov bilges txias shrink ntawm cov khoom, uas ua rau iav tsis sib xws thaum tshav kub kub expansion ntawm qhov chaw, qhov tsis sib xws, qhov sib txawv loj heev Nws yuav tawg lub iav.
Nyob rau tib lub sijhawm, iav yog cov khoom siv nruj heev, cov cua sov hloov mus qeeb qeeb, lub khob tuab dua, vim qhov kub ntawm qhov sib txawv, qhov kub nce sai, qhov yooj yim dua yog tawg.Qhov no txhais tau hais tias qhov kub ntawm qhov sib txawv ntawm cov dej kub npau npau thiab lub khob loj heev thiab lub khob yuav tawg.Yog li ntawd, qhov kub ntawm cov iav tuab feem ntau yog "-5 txog 70 ° C", lossis ntxiv dej txias me ntsis thiab tom qab ntawd me ntsis dej kub ua ntej nchuav dej npau npau.Thaum lub khob sov, ncuav dej tawm thiab ntxiv boiling dej dua.
Kev pabcuam kub ntawm lub khob kub kub
Cov yam ntxwv zoo dua ntawm cov iav borosilicate siab yog tias nws muaj cov coefficient tsawg heev ntawm thermal expansion, uas yog li ib feem peb ntawm cov iav zoo tib yam.Nws yog insensitive rau kub thiab tsis muaj thermal expansion thiab contraction ntawm cov khoom, yog li nws muaj kub tsis kam thiab siab thermal stability.Nws tuaj yeem siv los tuav dej kub.
Txawm li cas los xij,Uplusceeb toom rau koj, tsis txhob siv cov iav tempered ntawm kev ua lag luam ua lub khob uas tsis muaj qhov kub thiab txias.Kev siv kub ntawm cov iav tempered thiab iav zoo tib yam yog tib yam, feem ntau hauv qab 70 degrees, thiab koj yuav tsum tau ceev faj siv nws.
Koj tuaj yeem tso siab rau xaivUplus siab boron iavtsom iav los muab kev ruaj ntseg rau koj tsev neeg.
Nws kuj txhawb cov txheej txheem xws li thermalsublimation
