Cov yeeb yaj kiab ua liaj ua teb, ua ib qho tseem ceeb hauv kev tsim khoom ua liaj ua teb, tau hloov pauv thiab tsim kho tshiab, ua ib qho kev txhawb nqa tseem ceeb rau kev ua kom cov qoob loo loj hlob zoo thiab txhim kho cov qoob loo thiab zoo. Cov yeeb yaj kiab ua liaj ua teb feem ntau muab faib ua cov hom hauv qab no:
Zaj duab xis:siv los npog cov tsev cog khoom thiab cov tsev cog khoom kom muab ib puag ncig cog qoob loo zoo.
Zaj duab xis mulch:ncaj qha npog cov av saum npoo, siv rau kev khaws cia cua sov, khaws cia noo noo thiab tswj cov nroj tsuag.
Zaj duab xis tshwj xeeb:xws li zaj duab xis tawg, zaj duab xis tiv thaiv kev laus, thiab lwm yam, nrog rau cov haujlwm tshwj xeeb ntawm zaj duab xis ua liaj ua teb.
Nrog rau kev txhim kho tas mus li ntawm kev ua liaj ua teb, kev ua lag luam thiab cov neeg siv khoom xav tau kev ua tau zoo ntawm cov yeeb yaj kiab ua liaj ua teb. Cov yeeb yaj kiab ua liaj ua teb nrog 10% txog 20% metallocene polyethylene ntxiv rau muaj cov yam ntxwv ntawm lub zog siab, tiv taus kua muag zoo, kis tau lub teeb zoo thiab kaw zoo.
Metallocene polyethylene yog siv dav ua cov khoom siv raw los txhim kho cov yam ntxwv ntawm cov khoom. Muaj cov ntaub ntawv tseem ceeb, metallocene polyethylene siv rau hauv kev ua liaj ua teb zaj duab xis txog li 40%, uas feem ntau yog siv rau hauv nruab nrab thiab siab kawg ntawm zaj duab xis tsev, kev siv zaj duab xis tsuas yog me me xwb, hauv nruab nrab thiab siab kawg ntawm zaj duab xis tsev feem ntau yog PO zaj duab xis, EVA zaj duab xis, PE ob txheej tiv thaiv zaj duab xis thiab lwm yam zaj duab xis ua haujlwm.
Cov txiaj ntsig ntawm metallocene polyethylene hauv cov yeeb yaj kiab ua liaj ua teb:
Lub zog thiab kev tiv thaiv kua muag:Cov yeeb yaj kiab ua liaj ua teb ua los ntawm metallocene polyethylene muaj zog dua thiab tiv taus kua muag zoo, uas pab ua kom lub neej ua haujlwm ntev dua ntawm cov yeeb yaj kiab ua liaj ua teb.
Lub teeb kis tau:Nws muaj lub teeb zoo dua, uas yog qhov zoo rau photosynthesis ntawm cov qoob loo.
Kev laus tiv taus:metallocene polyethylene muaj kev tiv thaiv kev laus zoo, tshwj xeeb tshaj yog nyob rau hauv thaj chaw tiaj tiaj, thiab tuaj yeem hloov kho rau qhov chaw ib puag ncig nrog qhov sib txawv ntawm qhov kub thiab txias ntawm nruab hnub thiab hmo ntuj thiab qhov muaj zog ntawm lub hnub ci.
Metallocene polyethylene (mPE) muaj viscosity yaj siab vim nws qhov kev faib tawm qhov hnyav molecular nqaim thiab cov qauv molecular, uas tuaj yeem ua rau muaj teeb meem ntws tsis zoo. Tshwj xeeb, mPE qhia txog viscosity yaj siab hauv qhov ntau ntawm shear rate thiab tsis muaj kev nkag siab zoo rau shear, uas yuav ua rau ntws tsis zoo thiab muaj teeb meem ua haujlwm thaum lub sijhawm extrusion.
Yuav kom txhim kho cov txheej txheem ua cov metallocene polyethylene, ntau lub tuam txhab xaiv ntxiv cov khoom pab ua cov txheej txheem, xws li fluoropolymer cov khoom pab ua cov txheej txheem (PPAs), uas tuaj yeem txhim kho cov txheej txheem ua cov txheej txheem ntawm mPE (metallocene polyethylene). PPAs txhim kho cov txheej txheem polymer los ntawm kev ua haujlwm hauv lub xeev molten ntawm cov polymer, tshem tawm cov yaj tawg, daws cov teeb meem pwm tsim, thiab txhim kho qhov chaw ua tiav thiab cov txiaj ntsig ntawm zaj duab xis.
Thoob ntiaj teb, PFAS siv dav hauv ntau yam kev lag luam thiab cov khoom siv rau cov neeg siv khoom, tab sis nws cov kev pheej hmoo rau ib puag ncig thiab kev noj qab haus huv ntawm tib neeg tau ua rau muaj kev txhawj xeeb dav dav. Raws li European Chemicals Agency (ECHA) tshaj tawm tsab cai txwv tsis pub muaj PFAS rau pej xeem hauv xyoo 2023, ntau lub lag luam kuj tab tom nrhiav cov khoom siv PPA uas tsis muaj PFAS ua lwm txoj hauv kev.
Yuav kom ua tau raws li qhov sib txawv ntawm lub sijhawm, SILIKE tau tsim kho tau zooCov khoom siv ua cov polymer uas tsis muaj PFAS (PPAs)los ntawm kev siv cov cuab yeej siv thev naus laus zis tshiab kawg thiab kev xav tshiab, ua rau muaj kev pab txhawb zoo rau kev tiv thaiv ib puag ncig thiab kev txhim kho kom ruaj khov. Thaum ua kom ntseeg tau tias kev ua haujlwm zoo thiab qhov zoo ntawm cov ntaub ntawv, cov khoom no zam kev pheej hmoo ib puag ncig thiab kev noj qab haus huv uas cov tshuaj PFAS ib txwm muaj, tsis yog tsuas yog ua raws li daim ntawv txwv PFAS uas ECHA tau tshaj tawm rau pej xeem xwb tab sis kuj muab lwm txoj hauv kev nyab xeeb thiab txhim khu kev qha rau peb cov neeg siv khoom.
