FAQ

Cov iav dub ua los ntawm dab tsi?
Lawv yog tsim los ntawm borosilicate iav (Hom 3.3) nrog rau qhov sib ntxiv ntawm cov xim inorganic, xws li kev hloov pauv hlau oxides, kom ua tiav cov xim tsis sib xws, opaque xim dub thoob plaws tag nrho lub ntim ntawm lub pob.

Puas yog xim dub yog txheej lossis hauv cov khoom siv?
Cov xim tsis yog txheej txheej. Nws yog ib qho khoom vaj khoom tsev, homogeneous ntawm cov khoom siv iav nws tus kheej, txhais tau tias nws yuav tsis ploj, tev, lossis hnav tawm raws li kev siv ib txwm, kom ntseeg tau tias muaj qhov tsis zoo.

Dab tsi yog qhov txiaj ntsig tseem ceeb ntawm cov pob iav dub tshaj qhov tseeb?
Qhov txiaj ntsig tseem ceeb yog lawv qhov ua tiav opacity rau ultraviolet (UV) thiab pom lub teeb. Qhov no ua rau lawv qhov tseem ceeb rau cov ntawv thov uas xav tau lub teeb thaiv kom tsis txhob muaj cov tshuaj tiv thaiv photochemical, tiv thaiv lub teeb - cov ntaub ntawv rhiab heev, lossis tshem tawm cov teeb pom kev tsis zoo hauv cov tshuab kho qhov muag, thaum khaws tag nrho cov tshuaj thiab thermal zog ntawm borosilicate iav.

Cov pob iav dub puas muaj tib lub thermal shock tsis kam zoo li cov pob ntshiab borosilicate?
Yog lawm. Lawv tau tsim los ntawm tib lub borosilicate iav 3.3 cov khoom siv hauv paus, uas muaj cov coefficient tsawg heev ntawm thermal expansion (~ 3.25 x 10⁻⁶ / K). Yog li ntawd, lawv muaj qhov zoo tib yam thermal shock tsis kam thiab tuaj yeem tiv taus qhov kub thiab txias hloov.

Cov pob no puas yog hluav taws xob conductive?
Tsis yog. Zoo li txhua iav, lawv yog cov hluav taws xob zoo heev. Cov cuab yeej no ua rau lawv tsim nyog rau kev siv hluav taws xob thiab hluav taws xob ib puag ncig uas tsis yog -conductive, static-dissipative, lossis spark- cov khoom pov thawj yuav tsum tau.
