Xyoo tsis ntev los no, ntau hom ntaub ntawv polymer tau siv dav hauv ntau qhov chaw lag luam thiab thaj chaw hauv peb lub neej niaj hnub, kev tsim khoom thiab kev tsim kho hauv zej tsoom, thiab tau ua lub luag haujlwm tseem ceeb hauv kev tsim kho kev lag luam hauv lub teb chaws. Txawm li cas los xij, cov ntaub ntawv zoo li polymer feem ntau yog nplaim taws, thiab daim ntawv thov ntawm cov nplaim hluav taws tuaj yeem daws qhov teeb meem no kom zoo.
Yav dhau los, feem ntau ntawm lawv tsuas yog brominated nplaim taws retardants, tab sis lawv tsis yog-cov khoom siv ib puag ncig. Xyoo tsis ntev los no, ntau lawm tau raug txwv los ntawm txoj cai. Kev txhim kho kev cia siab ntawm halogen-nplaim taws nplaim hluav taws xob rau PC tau maj mam hloov chaw ua lag luam ntawm ABS brominated nplaim taws teeb meem.
Halogen-nplaim nplaim retardant mov yog nyob rau hauv luv luv thiab kev txhim kho zeem muag tau zoo dua
Lub ntiaj teb ua lag luam' s loj hlob xav tau rau phosphorus nplaim taws retardants tsuas yog vim:
1. Kev siv tus nqi zoo ntawm halogen tsis pub nplaim retardant engineering yas polycarbonate PC yog txhim kho tau zoo heev
Xyoo tsis ntev los no, vim tias qhov kev lag luam hauv PC muaj peev xwm ntau ntxiv, tus nqi tau poob qis. Tus nqi ntawm PC tau poob los ntawm 38,500 yuan / tuj hauv 2005 mus txog 14,000 yuan / tuj, thiab tus nqi ntawm decabromodiphenylethane tau nce siab dua nyob rau xyoo tas los no. Tus nqi sawv ntawm kwv yees li 30,000 yuan / ton hauv 2017 txog 60,000 yuan / tuj.
Lub PC tam sim no + BDP nplaim hluav taws kev ua haujlwm yog li 0.18 lab yuan / tuj qis dua ABS + bromine nplaim taws kev ua haujlwm. Tus nqi kom zoo dua ntawm PC + halogen-tsis muaj phosphorus nplaim taws retardant yog pom tseeb heev. Nyob rau tib lub sijhawm, kev ua tau zoo ntawm PC halogen tsis muaj nplaim taws ua kom rov zoo li qub tshuab hluav taws xob, suav nrog cov khoom siv kho tshuab, nws tseem zoo tshaj ABS engineering plastics.
2. EU' s txoj cai tsis pub muaj halogen yuav tau siv sai los txhawb kev lag luam txhim kho cov nplaim taws cov neeg tsis ua haujlwm.
Lub Kaum Ob Hlis 5, 2019, European Union tau muab cov kev cai (EU) 2019/2021, uas tau tsim cov eco-tsim cov cai rau cov khoom siv hluav taws xob hauv EU Eco-Design Directive rau cov khoom siv hluav taws xob (ErP Directive, 2009/125 / EC) )). Halogen-based nplaim taws rov qab siv lub plhaub thiab pluaj taub; yas qhov chaw ntau dua 50g yuav tsum tau muab cim kom meej meej nrog hom khoom. Yog tias lawv muaj cov nplaim taws retardants, cov ntaub ntawv sib raug ntawm cov nplaim retardants yuav tsum cim. Txoj cai tshiab yuav tau ua tiav txij li lub Peb Hlis 1, 2021.
Txawm hais tias EU txoj cai tsis pub hloov txoj haujlwm halogen yuav raug coj los siv rau lub Peb Hlis 1 xyoo tom ntej, cov tuam txhab cuam tshuam yuav tsum npaj ua ntej. Rau cov tuam txhab no, nws siv sijhawm los hloov lub pwm, kev sim ntau lawm thiab kev tsim tawm huab hwm coj thaum kawg. Txij li ib nrab xyoo kawg ntawm xyoo tas los no, vim tias qhov kev txhaj tshuaj sib txawv txo cov nqi ntawm cov tshuab hluav taws xob sib txawv, cov tuam ntxhab tau maj mam rov pib hloov pwm. Qhov tseem ceeb halogen-tsis muaj phosphorus nplaim taws rov qab los ntawm ntau lub tuam txhab ua tshuab hloov kho lub tuam txhab kev lag luam tau ntsib qhov kev loj hlob loj.
3. Xyoo tsis ntev los no, cov cai tiv thaiv ib puag ncig ntawm kev tiv thaiv ib puag ncig tau ua rau txo qis kev muaj peev xwm ntawm cov nplaim hluav taws;
Los ntawm cov khoom siv sab, txoj kev tsim khoom tshiab ntau ntxiv rau 2-3 xyoos tom ntej no tau txwv heev. Hauv ob xyoos dhau los, tshwj tsis yog 20,000-tuj lub tshuab hluav taws xob yas nplaim retardant ntau lawm kab hauv kev tsim kho los ntawm Wansheng, tsis muaj lwm qhov muaj peev xwm loj uas tuaj yeem tso rau hauv ntau lawm. Nws yog deb ntawm ua tau raws li kev ua lag luam xav tau. Tam sim no, phosphorous nplaim retardant tuam ntxhab tsim tawm ntawm qhov muaj peev xwm tag nrho, thiab lub khw kev lag luam yog nquag, uas tau ua rau cov nqi tsis ntev los no nce ntxiv. Raws li tam sim no, kev lag luam kev hais lag luam tawm yog 25,000 yuan / tuj. Cov nce zuj zus xyoo no tau Ntau dua 45%, txawm tias qhov tshwm sim ntawm qaij mus rau kev txiav txim.
4. Qhov kev thov rau phosphorus nplaim taws rov qab hauv cov tsheb tshiab lub zog hluav taws xob, khoom siv hluav taws xob thiab lwm yam lag luam txuas ntxiv tau nce ntxiv
Raws li qhov chaw lag luam, cov neeg muas zaub qis yog ua nws pib qhov chaw tuam txhab thiab cov khoom siv hauv tsev. Keeb kwm, txhua tus neeg' s lub tswv yim kev tiv thaiv ib puag ncig tsis muaj zog, thiab bromine nplaim taws teeb meem tau siv ntau ntawm tus nqi qis. Tabsis zaum no nws txawv lawm. Nrog rau qhov yuav tsum tau tshaj tawm cov cai tswjfwm, peb yuav tsum kho cov txheej txheem ntau lawm thiab siv cov nplaim hluav taws xob tsis muaj teeb meem halogen.
