Txias hydrogenation yog dav siv rau kev rov qab zoo ntawm high-purity silicon hmoov los ntawm cov khoom. Ntawm cov neeg tsim khoom hauv tsev, cov txheej txheem txias hydrogenation yuav luag siv los kho cov khoom lag luam. Nyob rau hauv peb lub xyoos dhau los, tag nrho cov txias hydrogenation muaj peev xwm ntawm xws li producers tau mus txog 31.45 lab tonnes ib xyoo, nrog rau qhov loj hydrogenation muaj peev xwm ntawm ib chav tsev mus txog 150,000 tonnes / xyoo, nrog ib tug Kev siv hluav taws xob ntawm kwv yees li 0.5 kWh / kg-TCE, uas yog ntau dua 70% qis dua qhov kub hydrogenation.
Kev siv dav dav ntawm cov khoom lag luam. Nyob rau hauv cov txheej txheem high-purity silica hmoov, lub pob khoom los ntawm cov khoom yog huv si thiab xa rov qab mus rau qhov system siv; nyob rau hauv feem ntau cov tuam txhab, cov by-products silica thiab silicon tetrachloride yog disproportionated nyob rau hauv lub xub ntiag ntawm ib tug catalyst los tsim silica, uas yog purified thiab xa rov qab mus rau lub system siv. hCl raug xa mus rau synthesis lossis ncaj qha mus rau txias hydrogenation. Los ntawm qhov kev ntsuas no, cov khoom siv raw tau txo qis heev.
Txoj kev loj hlob thiab kev siv ntawm adsorption thiab tshem tawm impurities, pressurized distillation los purify siab purity silica hmoov nrog zoo sieve phaj incorporating fillers, thiab purification coupling txheej txheem tau txhim kho cov khoom zoo thiab txo lub zog noj. Kev lag luam ib txwm siv chav ua noj los ntawm 200 tonnes / tonne hauv 2009 - txo mus rau tam sim no 30 tonnes / tonne lossis tsawg dua, chav noj haus txo qis dua 70%. Cov txheej txheem kev sib txuas ua kom huv kuj raug tshem tawm lossis txo qhov saum toj kawg nkaus ntawm tus pej thuam circulating dej noj 45% ~ 70%.
Safe thiab environmentally friendly. Kev tsim cov khoom zoo li no yog ib zaug suav tias yog kev lag luam "muaj kuab paug heev", uas yog tshwm sim los ntawm silicon tetrachloride, ib qho khoom siv los ntawm cov txheej txheem ntau lawm ntawm high-purity silicon hmoov. Silicon tetrachloride tuaj yeem siv los ua cov khoom siv raw rau polysilicon, thiab tuaj yeem hloov mus rau hauv silicon trichloride ntawm tus nqi qis los ntawm cov txheej txheem hydrogenation thiab rov qab mus rau qhov system siv; nws tseem tuaj yeem siv rau kev tsim cov khoom siv high-tech. Cov no yog cov txiaj ntsig zoo los txo cov nqi tsim khoom. Nyob rau hauv xyoo tas los no, cov tuam txhab lag luam hauv tsev tau hloov kho lawv cov txheej txheem, kev tswj hwm tau muaj zog, cov chaw tiv thaiv ib puag ncig tau tswj hwm kev saib xyuas online, thiab tib neeg kev paub txog kev tiv thaiv ib puag ncig tau maj mam nce.
