Qhov tseem ceeb thiab kev txhim kho keeb kwm ntawm nplaim taws - Cov khoom siv retardant

Hauv lub neej niaj hnub no, kev nyab xeeb hluav taws yog qhov tseem ceeb tshaj plaws. Raws li lub ntsiab lus tseem ceeb los tiv thaiv thiab tswj hluav taws kub, nplaim taws - cov khoom siv hluav taws xob tau siv dav hauv ntau yam xws li kev tsim kho, kev thauj mus los, hluav taws xob thiab khoom siv hluav taws xob, thiab aerospace. Piv txwv li, hauv kev tsim kho, nplaim taws - retardant khoom yog siv los ua qhov rooj hluav taws, hluav taws kub, thiab hluav taws kub-tiv thaiv txheej, uas tuaj yeem tiv thaiv kev sib kis ntawm hluav taws thiab nce sijhawm rau cov neeg khiav tawm thiab cawm hluav taws. Hauv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob, kev siv cov nplaim hluav taws xob - cov khoom siv hluav taws xob hauv cov xov hlau, cables, thiab cov khoom siv hluav taws xob txo qhov kev pheej hmoo ntawm hluav taws xob hluav taws xob. Nrog rau kev txhim kho ntawm ib puag ncig kev paub thiab kev nrov ntawm lub tswv yim ntawm kev txhim kho kom ruaj khov, cov kev xav tau siab dua tau muab tso rau pem hauv ntej rau kev ua phooj ywg ib puag ncig thiab rov ua dua lub peev xwm ntawm cov nplaim hluav taws - cov khoom siv hluav taws xob. Kev soj ntsuam lub neej voj voog (LCA) tau dhau los ua ib qho cuab yeej tseem ceeb rau kev ntsuas qhov cuam tshuam ib puag ncig thiab rov ua dua cov nplaim taws - cov ntaub ntawv tsis zoo.

Methodological Foundation ntawm LCA

Cov Lus Txhais thiab Cov Ntsiab Cai ntawm LCA

LCA yog ib txoj kev ntsuam xyuas “cradle – to – grave”. Nws npog tag nrho lub neej voj voog ntawm ib yam khoom lossis kev pabcuam, los ntawm cov khoom siv raw, kev tsim khoom, kev thauj mus los, siv rau kev pov tseg zaum kawg. Nws lub hom phiaj yog txhawm rau txheeb xyuas thiab ntsuas qhov kev siv peev txheej, kev siv hluav taws xob, thiab emissions rau ib puag ncig hauv txhua theem, thiab ntsuas kev ntsuas lawv qhov cuam tshuam rau ib puag ncig.

Cov kauj ruam tseem ceeb ntawm LCA

1. Lub hom phiaj thiab Scope txhais: Qhia meej lub hom phiaj ntawm qhov kev ntsuas, xws li seb nws puas yog los sib piv qhov kev ua haujlwm ib puag ncig ntawm cov nplaim hluav taws sib txawv - cov khoom siv hluav taws xob los yog txhim kho cov txheej txheem tsim khoom ntawm cov nplaim hluav taws - cov khoom siv retardant. Txiav txim siab tus ciam teb, txhais cov txheej txheem thiab theem twg muaj nyob rau hauv qhov kev ntsuam xyuas, xws li seb puas yuav xav txog cov theem ua ntej ntawm cov khoom siv raw thiab cov khoom siv rov ua dua tom qab cov khoom siv ua haujlwm tiav. Nyob rau tib lub sijhawm, txiav txim siab lub luag haujlwm ua haujlwm raws li tus qauv ntsuas rau kev ntsuas qhov cuam tshuam ib puag ncig, xws li kev cuam tshuam ib puag ncig tsim los ntawm kev tsim txhua 1 tuj ntawm cov nplaim taws - cov khoom siv retardant.
