Cov tuab tuab ntawm cov iav txhuas yog 10mm 12mm 15mm 18mm 20mm.10mm sib haum rau 2 txhuas sib npaug, 12 hli yog 2.5 txhuas sib npaug, 15 hli yog 3 txhuas sib npaug, 18 hli yog 4 txhuas sib npaug, thiab 20 hli sib npaug. Ntau tshaj 20mm tuab tuaj yeem kho tau.Feem ntau, 3-4 txhuas sib npaug yog siv hauv CT chav, thiab 2-3 txhuas sib npaug yog siv hauv tsev kho mob stomatological.
Tam sim no, ZF2 txhuas iav thiab ZF3 txhuas iav siv nyob rau hauv Tuam Tshoj yog yuav luag tib yam, cov hlau lead sib npaug thiab ceev yog tib yam, qhov ceev yog 4.2, thiab lub teeb transmittance mus txog 95%, yog li peb tsis tas yuav entangle. kev sib raug zoo ntawm zf2 thiab zf3 lead iav, uas yog tiag tiag iav.
ZF6 txhuas iav muaj cov yam ntxwv ntawm cov ntsiab lus txhuas siab, kev tiv thaiv zoo, lub teeb yuag, thiab muaj zog thiab ruaj khov, feem ntau yog siv rau hauv nuclear fais fab nroj tsuag, atomic zog siv thiab lwm yam kev lag luam nuclear.
Lead iav yog tshuaj ruaj khov zoo dua li cov iav ntshiab phosphate.Txawm li cas los xij, yog tias cov txheej txheem phosphate ua ke nrog lub tshuab silicate, lub tshuab desalination, lossis lwm cov tshuab, cov phenomena miscible tshwm sim tam sim ntawd -7.4.3 siab lead silicate iav, xim nyob ntawm cov qauv.High lead silicate iav feem ntau yellowish ntsuab.Hauv cov iav pob tshab, qhov cuam tshuam ntawm tooj liab lossis ions ntawm iav thiab kev hloov ntawm iav qauv muaj qhov cuam tshuam loj rau kev xa cov iav txhuas.
Txij li thaum nws tsim, peb lub Hoobkas tau tsim thawj cov khoom lag luam hauv ntiaj teb nrog kev ua raws li lub hauv paus ntsiab lus zoo ua ntej.Peb cov khoom tau txais lub koob npe nrov hauv kev lag luam thiab muaj txiaj ntsig zoo ntawm cov neeg siv khoom tshiab thiab qub ..
