Cov iav rwb thaiv tsev, lub teeb kis tau tus mob, kev ua haujlwm ruaj khov, ntau hom vim siv ntau zaus thiab muaj cov yam ntxwv sib txawv, daim ntawv thov ntau yam dav heev. Thaum peb xaiv iav, ntxiv rau kev saib xyuas tus nqi, peb kuj yuav tsum muaj kev nkag siab qee yam ntawm nws hom thiab kev ua tau zoo, txhawb kev muaj zog thiab tsis txhob muaj qhov tsis muaj zog, txhawm rau nrhiav cov khoom tsim nyog. Peb tau sau cov ntaub ntawv los sau cov kab lus no los pab koj nkag siab cov yam ntxwv ua haujlwm thiab cov khoom siv raw ntawm cov iav borosilicate siab.
Cov lus qhia luv luv rau kev ua haujlwm ntawm siab borosilicate iav raj
High borosilicate glass is made by using the conductive characteristics of glass at high temperature, by heating inside the glass to achieve glass melting, and processed by advanced production technology. In the glass tube, SiO2 (silicon oxide) >78%, B2O3 (boron oxide) >10%, cov ntsiab lus ntawm silicon thiab boron yog siab heev.
High borosilicate iav khoom series
1, bar: tuaj yeem siv rau kev ua cov khoom siv teeb pom kev zoo, nyiam nyob hauv tsev thiab txawv teb chaws
2, yeeb nkab: tuaj yeem siv rau cov twj siv tshuaj nrog cov kav dej, cov kav dej tshuaj, khoom siv tes ua nrog cov kav dej.
3, hnub ci lub tshuab nqus tsev raj nrog lub raj dawb: cov khoom siv borosilicate siab tau siv dav hauv hnub ci zog, dav siv hauv hnub ci iav ntim / teeb / cov khoom siv tshuaj yeeb dej caw / cov khoom siv hluav taws xob sib pauv.
4, high technology niaj hnub tsim nyog
Thib ob, siab borosilicate iav raj tsim cov ntaub ntawv raw
Raws li cov khoom ntawm cov oxides qhia, nws tuaj yeem muab faib ua kua qaub oxide raw khoom, alkali hlau oxide raw khoom thiab alkali ntiaj teb hlau oxide raw khoom.
① Acid oxide raw cov ntaub ntawv: muaj SiO2, B2O3, Al2O3 thiab lwm yam ntaub ntawv raw. SiO2 yog lub cev pob txha ntawm cov qauv iav hauv silicate iav. Nws muab lub iav qhov siab, zoo tshuaj stability, tshav kub tsis kam thiab tsis tshua muaj expansion, tab sis nws yuav ua rau kom lub melting kub ntawm lub iav thiab ua rau kom lub viscosity. Cov khoom siv raw ntawm SiO2 yog silica xuab zeb lossis sandstone thiab quartzite. Ntxiv B2O3 rau iav tuaj yeem txo qhov thermal expansion ntawm iav, txhim kho qhov ntsuas qhov ntsuas kub, tiv thaiv tshav kub thiab tshuaj lom neeg yaig, txo cov viscosity ntawm iav ntawm qhov kub siab dua, thiab txhim kho cov viscosity ntawm iav ntawm qhov kub thiab txias. Cov khoom siv raw rau B2O3 yog borax lossis boric acid. Ntxiv Al2O3 rau iav tuaj yeem txo cov iav crystallization nyiam thiab txhim khu kev ruaj ntseg tshuaj, txhim kho qib, thiab ua kom cov iav viscosity. Cov ntaub ntawv raw khoom feem ntau yog feldspar nrog K2O lossis Na2O thiab SiO2, thiab cov khoom siv alumina kuj tseem siv tau. Cangzhou Tianchang technology iav khoom Hoobkas muaj kev paub nyob rau hauv tsim ntau hom siab borosilicate iav raj
② Alkali hlau oxide raw khoom: Na2O, K2O raw khoom. Qhov sib ntxiv ntawm Na2O thiab K2O rau cov iav tuaj yeem txo qhov kub thiab viscosity, tab sis nws yuav ua rau cov tshuaj ruaj khov ntawm cov iav tsis zoo. Cov khoom siv raw yog dej qab zib tshauv (Na2CO3) thiab potassium alkali (K2CO3).
③ Alkaline ntiaj teb hlau oxide raw khoom: muaj CaO, MgO, BaO, ZnO, PbO raw khoom. Ntxiv CaO thiab MgO rau iav tuaj yeem ua rau tsis muaj zog crystallization ntawm sodium-silicon iav, txhim kho cov tshuaj lom neeg ruaj khov, txo cov viscosity ntawm iav ntawm qhov kub thiab txias, thiab txhawb cov melting thiab clarification ntawm iav, tab sis lub viscosity nce sai heev thaum kub txo, thiab kev ua haujlwm molding yog qhov nyuaj. Cov khoom siv raw yog limestone (CaCO3) thiab magnesite (MgCO3), lossis dolomite muaj CaO thiab MgO. BaO thiab ZnO feem ntau ntxiv rau lub khob los kho cov tshuaj ruaj khov thiab qhov ntsuas qhov ntsuas ntawm lub iav, thiab cov khoom siv raw khoom feem ntau yog ZnO thiab BaCO3, BaSO4 lossis Ba (NO3)2. Qhov sib ntxiv ntawm PbO hauv iav tuaj yeem txhim kho qhov ntsuas qhov cuam tshuam thiab tawg, yog li lub iav tuaj yeem nqus cov kab hluav taws xob luv luv, tib lub sijhawm, qhov tshwj xeeb lub ntiajteb txawj nqus tau nce, qhov kub melting yog txo, thiab cov hlau infiltration zoo. Cov khoom siv raw rau PbO yog cov hmoov txhuas liab thiab cov hmoov txhuas daj lossis cov hmoov txhuas nitrate.
Tsis tas li ntawd, cov iav tawg kuj yog cov khoom siv tseem ceeb, feem ntau hu ua clinker, tuaj yeem yaj ntawm qhov kub thiab txias, ua rau cov iav sib xyaw ua ke.
