Yog lawm, Polyurethane cov menyuam yaus cov pob khoom ua si tuaj yeem suav tias yog tus qauv ib puag ncig thiab cov qauv kev nyab xeeb. Cov hauv qab no yog cov ncauj lus kom ntxaws:
🌿 1. Cov khoom siv ib puag ncig
Cov ntaub ntawv Polyurethane lawv tus tuaj yeem hloov kho kom ua tiav cov kev phooj ywg siab ib puag ncig. Piv txwv li, ywg dej {-} Raws polyurethane resin (synthesized los ntawm kev sib txuas nrog polyurethane expolymer) tau kawm txog kev siv hauv cov menyuam cov khoom ua si. Cov ntaub ntawv no tsis - kev ua kom zoo nkauj (xws li cov khoom siv ua kom zoo nkauj (xws li tensene diisocyanate (TDI), Monofluoroethylene, thiab cov hlau hnyav, 5 yog li ua tau txoj kev xav tau nruj kev nyab xeeb rau cov menyuam yaus cov khoom ua si.
🌱 2. Cov txheej txheem ntau lawm thiab rov ua dua tshiab
Kev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb: Cov txheej txheem ntau lawm rau Polyurethane kev ua si cov khoom ua si tuaj yeem ua tau zoo rau kev txo cov pa phem ib puag ncig. Piv txwv li, cov ntaub ntawv raw nrog cov zaub mov tsis tshua muaj zog (VOC) cov pa hluav taws xob tuaj yeem siv, thiab cov txheej txheem uas tsis tas yuav tsum muaj cov pwm hluav taws xob. Txo cov pwm hluav taws xob.
Rov qab siv dua: Polyurethane cov ntaub ntawv muaj cov khoom siv siab dua. Piv txwv, cov dej {-} Raws li Polyurethane Resin tau hais txog saum toj no tuaj yeem txo cov khib nyiab los ntawm kev pov tseg lub cev lossis tshuaj ua dua tshiab .6
📘 3. Ua raws li cov qauv kev nyab xeeb thoob ntiaj teb
Polyurethane Me Nyuam Cov Khoom Ua Si yuav tsum dhau ntau cov ntawv pov thawj kev nyab xeeb thoob ntiaj teb kom ntseeg tau tias lawv cov yam ntxwv ib puag ncig:
Suav Txheej Txheem Suav GB 6675: Yuav tsum muaj cov ntsiab lus phthalate tsawg dua lossis sib npaug 0.1% thiab txhuas tsiv teb tsaws tsawg dua lossis sib luag ntawm 90mg / KG.3
EU Cov Qauv Kawm EN 71: Cov kev cai nruj ntawm cov hlau tsiv teb tsaws chaw, kev nyab xeeb phthalate, thiab kev tiv thaiv lub cev (xws li qhov chaw tiv thaiv me me) .3
US Txheem ATTM F963: Txwv tsis pub siv cov khoom muaj kev phom sij (xws li cov hmoov txhuas thiab phthalates) thiab yuav tsum tau kuaj cov khoom cev.3
Cov qauv no kom cov khoom ua si polyurethane muaj kev phom sij thiab ua tau raws li cov qauv ib puag ncig thaum kev tsim khoom.
⚠️ 4. Kev ceev faj thiab kev lag luam kev lag luam
Additate tswj: Ntau yam kev tsim khoom polyurethane tuaj yeem siv cov tshuaj tiv thaiv lossis cov neeg sawv cev ua npuas dej tau hloov (xws li cov khoom siv ua npuas ncauj (xws li cov nroj tsuag raw (xws li tsob nroj raw {{}} derived Polyether Polyols) .56
Cov ntaub ntawv kev lag luam: Piv txwv li, qee cov tuam txhab tsim cov polyurethane kev ua si ntawm cov khoom lag luam (xws li TPU Comprosite Fabrics) .46
💎 Qhov xaus
Zuag qhia tag nrho, Polyurethane menyuam cov khoom ua si, muab lawv siv cov khoom muaj kev nyab xeeb zoo (xws li tsis muaj kev nyab xeeb rau cov qauv kev nyab xeeb) thiab tsis muaj kuab lom neeg muaj kuab, thiab tsis muaj kuab paug nyob rau hauv kev tsim khoom. Cov neeg siv khoom tuaj yeem paub ntxiv cov kev ua tau zoo ib puag ncig ntawm cov khoom lag luam los ntawm kev kuaj xyuas lawv cov ntawv pov thawj ib puag ncig (xws li ncav cuag thiab ROHS) thiab cov ntawv lo (ROHS)
