Dimethyltin dichloride siv rau dab tsi?
Cov ntawv thov tseem ceeb ntawmdimethyltin dichloride(CAS No. 753-73-1) feem ntau yog tsom mus rau kev tiv thaiv cov khoom siv, kev ua yas thiab cov ntaub ntawv tshwj xeeb, uas tuaj yeem muab faib ua peb pawg loj.
Hauv kev tiv thaiv hlau: "Hnav khaub ncaws tiv thaiv" rau cov hlau magnesium los pab txhawb kev txhim kho kev lag luam sib dua
Hauv cov teb uas muaj qhov xav tau siab heev rau cov khoom siv uas tsis hnyav, xws li kev tsim khoom siv dav hlau thiab tsheb, cov hlau magnesium tau txais kev nyiam dav vim lawv qhov zoo ntawm qhov hnyav sib dua thiab lub zog siab. Txawm li cas los xij, qhov khoom siv corrosion ntawm cov hlau magnesium tau dhau los ua "bottleneck" txwv lawv cov kev siv loj. Lub sijhawm no, kev tshwm sim ntawm DMCT tau muab kev daws teeb meem zoo rau qhov teeb meem nyuaj no.
Raws li cov ntaub ntawv kev lag luam, qhov kev thov hauv tebchaws rau DMCT siv rau hauv kev tiv thaiv xeb magnesium alloy yuav ncav cuag 6,000 tons hauv xyoo 2024, uas sawv cev rau kev loj hlob txhua xyoo ntawm 12%. Nrog rau kev nce ntxiv ntawm qhov kev thov rau cov khoom siv sib dua hauv kev lag luam xws li cov tsheb fais fab tshiab thiab cov tsheb tsis muaj neeg tsav, nws xav tias qhov kev thov loj hlob ntawm DMCT hauv daim teb no yuav nyob siab dua 10% hauv ob xyoos tom ntej, muab kev txhawb nqa zoo rau kev siv loj ntawm kev lag luam magnesium alloy.
Kev lag luam ua yas: PVC stabilizers yog "lub zog tseem ceeb", ua kom cov khoom zoo thiab kev nyab xeeb
Polyvinyl chloride (PVC), yog ib yam khoom siv dav dav uas muaj cov khoom tsim tawm ntau tshaj plaws hauv ntiaj teb, dimethyl tin Dichloride siv dav hauv cov teb xws li cov kav dej, cov profile, thiab cov yeeb yaj kiab. Txawm li cas los xij, thaum lub sijhawm ua thiab siv PVC, nws yooj yim puas tsuaj vim muaj ntau yam xws li kub thiab raug lub teeb, ua rau cov khoom tsis zoo, tawv thiab ua haujlwm poob qis. dimethyltin dichloride DMTC, ua lub hauv paus nruab nrab ntawm PVC cov khoom cua sov, tuaj yeem tiv thaiv kev puas tsuaj ntawm PVC thiab ua "lub zog tseem ceeb" los xyuas kom meej qhov zoo thiab kev nyab xeeb ntawm cov khoom PVC.
Kev tsim cov khoom siv zoo tshaj plaws: Muaj zog los ntawm cov ntaub ntawv ua ntej, pab txhawb kev tsim kho tshiab hauv kev lag luam hluav taws xob thiab lub zog tshiab
Ntxiv rau cov teb siv ib txwm muaj, kev siv dimethyltin dichloride DMCT hauv kev tsim cov khoom siv siab heev maj mam tshwm sim, tshwj xeeb tshaj yog hauv kev lag luam hluav taws xob thiab lub zog tshiab, qhov twg nws qhov txiaj ntsig ua cov khoom siv ua ntej tau raug tshawb nrhiav tas li.
Hauv kev ua haujlwm ntawm cov khoom siv hluav taws xob, cov yeeb yaj kiab tin oxide uas muaj cov khoom siv pob tshab yog cov khoom tseem ceeb ntawm cov khoom xws li cov kua siv lead ua kua thiab cov ntxaij vab tshaus kov. Tom qab ua tiav los ntawm cov txheej txheem tshwj xeeb,dimethyltin dichloride DMCT siv tau ua cov khoom siv zoo rau kev npaj cov yeeb yaj kiab tin oxide pob tshab. Piv nrog cov khoom siv ib txwm muaj, cov yeeb yaj kiab uas npaj los ntawm DMCT ua cov khoom siv raw muaj kev ua hluav taws xob siab dua thiab kev xa hluav taws xob ntau dua, uas tuaj yeem txhim kho qhov zoo ntawm daim duab thiab kov qhov rhiab heev ntawm cov khoom tso saib. Tam sim no, cov thev naus laus zis no tau siv rau ntau qhov chaw hauv ntau lub tuam txhab tso saib hauv tsev uas paub zoo, txhawb kev lag luam tso saib hauv tsev kom txhim kho mus rau qhov zoo dua.
Hauv kev lag luam ntawm lub zog tshiab, dimethyl tin dichloride kuj qhia tau tias muaj peev xwm siv tau zoo. Qee lub koom haum tshawb fawb tau qhia tias DMCT-derived organotin compounds tuaj yeem siv rau hauv kev npaj cov khoom siv electrode rau lub hnub ci cell, uas xav tias yuav txhim kho kev hloov pauv photoelectric ntawm lub hnub ci cell. Tam sim no, cov thev naus laus zis cuam tshuam tau nkag mus rau theem tsim khoom sim. Yog tias nws raug siv rau hauv kev lag luam yav tom ntej, nws yuav txhaj tshuaj tshiab rau hauv kev txhim kho ntawm kev lag luam zog tshiab.
Cov kws tshaj lij hauv kev lag luam taw qhia tias nrog kev nce qib tas mus li ntawm thev naus laus zis thiab kev txhim kho sai ntawm cov lag luam cuam tshuam, cov teb thov ntawmDMCTyuav raug nthuav dav ntxiv. Txawm li cas los xij, tib lub sijhawm, yuav tsum tau them sai sai rau cov teeb meem kev tiv thaiv ib puag ncig thaum lub sijhawm tsim khoom thiab siv. Los ntawm kev tsim kho tshiab, kev lag luam DMCT yuav tsum tau txhawb nqa kom txhim kho mus rau hauv kev coj ua ntsuab thiab ruaj khov, kom thiaj li muaj zog rau kev txhim kho ntawm ntau yam kev lag luam.
