PU ua npuas ncauj yog dab tsi?
Polyurethane ua npuas ncauj yog tsim los ntawm ib qho tshuaj tiv thaiv ntawmpolyolsthiabisocyanates, nrog rau cov catalysts, tshuab tshuab, surfactants, thiab lwm yam additives. Thaum lub sij hawm tsim khoom, cov khoom xyaw no hnov qab tsim cov qauv polymer ruaj khov uas muaj ntau lab lub hlwb me me.
Tom qab cov txheej txheem kho tiav lawm, cov tshuaj reactive tsis muaj nyob rau hauv lawv daim ntawv qub. Qhov tshwm sim yog cov khoom siv ruaj khov, ruaj khov uas muaj cov cushioning zoo heev, cuam tshuam kev nqus, rwb thaiv tsev, thiab qhov ntev stability.
Vim tias cov khoom kawg sib txawv ntawm cov tshuaj nyoos siv thaum tsim khoom, nws yog ib qho tseem ceeb kom paub qhov txawv ntawmkev ruaj ntseg ntau lawmthiabkev nyab xeeb ntawm cov neeg siv khoom.
Puas yog tiav PU Ua Npuas Ncauj?
Feem ntau, yog.
Kev kho mob siab polyurethane ua npuas ncauj tsim raws li cov qauv kev lag luam feem ntau suav tias muaj kev nyab xeeb rau kev siv txhua hnub. Nws yog feem ntau siv hauv cov khoom uas tib neeg cuam tshuam nrog txhua hnub, suav nrog:
Automotive sab hauv Cheebtsam
Kev kho mob cushions
rooj zaum
Rooj tog cushions
Memory ua npuas ncauj hauv ncoo
Cov khoom ua si thiab qoj ib ce
Muaj kev tiv thaiv qhov chaw
Thaum kho tau, polyurethane ua npuas ncauj feem ntau yog cov tshuaj ruaj khov thiab tsis tas li tso cov khoom tsis zoo nyob rau hauv ib txwm siv.https://www.custompolyurethanefoam.com/household-pu-foam/pu-bathtub-therapy-pillow.html
Txawm li cas los xij, cov khoom lag luam zoo nyob ntawm kev tsim kom raug, txheej txheem tsim khoom, thiab ua raws li cov cai tswj kev nyab xeeb.
Puas Muaj Kev Nyab Xeeb Kev Nyab Xeeb?
Txawm hais tias ua tiav PU ua npuas ncauj feem ntau muaj kev nyab xeeb, muaj cov xwm txheej uas yuav tsum tau ceev faj.
Thaum tsim khoom
Qhov kev pheej hmoo ntawm kev noj qab haus huv loj tshaj plaws tshwm sim thaum lub sijhawm tsim khoom ntau dua li tom qab cov khoom tiav lawm.
Cov neeg ua haujlwm tuav cov isocyanates nyoos thiab lwm yam tshuaj muaj zog yuav tsum hnav cov khoom tiv thaiv tus kheej tsim nyog (PPE) thiab ua haujlwm hauv qhov chaw zoo - qhov cua. Cov tshuaj no tuaj yeem ua rau daim tawv nqaij, qhov muag, thiab ua pa ua pa ua ntej lawv muaj kev cuam tshuam tag nrho.
Cov kws tshaj lij kev lag luam ua raws li cov txheej txheem kev nyab xeeb nruj kom txo tau cov neeg ua haujlwm raug.
Thaum lub sij hawm pib siv
Qee cov khoom tsim tawm tshiab polyurethane tuaj yeem tso tawm me ntsis tsw thaum xub ntim. Qhov no feem ntau hu uatawm -gassing.
Feem ntau, cov ntxhiab tsw yog los ntawm cov kab mob ntawm cov kab mob tsis haum xeeb (VOCs) uas tseem tshuav tom qab ntau lawm es tsis yog los ntawm polyurethane nws tus kheej.
Cov ntxhiab tsw feem ntau yuav txo qis hauv ob peb hnub yog tias cov khoom muab tso rau hauv qhov dej - qhov cua.
Thaum Hlawv
Zoo li ntau cov khoom siv hluavtaws, polyurethane ua npuas ncauj yuav tsum tsis txhob txhob txwm hlawv.
Thaum raug hluav taws kub los yog kub heev, PU npuas tuaj yeem decompose thiab tsim cov pa taws thiab cov pa phem. Qhov no yog vim li cas cov khoom siv polyurethane siv hauv kev thauj mus los rau pej xeem, kev kho mob, thiab rooj tog zaum feem ntau yuav tsum tau ua raws li cov qauv kev nyab xeeb tshwj xeeb.
Kev tiv thaiv hluav taws zoo yog qhov tseem ceeb rau txhua daim ntawv thov uas muaj cov ntaub ntawv polymer.
PU Ua Npuas Ncauj puas muaj cov tshuaj lom neeg?
Qhov no nyob ntawm cov khoom thiab cov chaw tsim khoom.
Reputable polyurethane manufacturers ua tib zoo tswj cov ntaub ntawv raw thiab cov txheej txheem ntau lawm kom ntseeg tau tias lawv cov khoom ua tau raws li kev nyab xeeb thoob ntiaj teb. Ntau cov khoom lag luam PU ua npuas ncauj raug kuaj xyuas kom ua raws li cov cai muaj feem xyuam rau cov khoom txwv thiab tshuaj lom neeg kev nyab xeeb.
Thaum muab cov khoom siv polyurethane, cov neeg yuav khoom feem ntau thov cov ntaub ntawv xws li:
REACH ua raws
Kev ua raws li RoHS
Cov Ntaub Ntawv Kev Nyab Xeeb Cov Ntaub Ntawv (MSDS / SDS)
VOC cov ntaub ntawv xeem (thaum tsim nyog)
Cov ntaub ntawv no pab xyuas kom meej tias cov khoom ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb ntawm lub khw lub hom phiaj.
Puas yog PU Foam muaj kev nyab xeeb rau kev siv tshuaj kho mob thiab cov neeg siv khoom?
Yog, thaum tshwj xeeb tsim thiab tsim rau cov ntawv thov.
Kev kho mob hauv cushions, kev txhawb nqa kev kho mob, cov cuab yeej orthopedic, thiab cov cuab yeej kho mob feem ntau siv cov ntaub ntawv tshwj xeeb polyurethane ua npuas ncauj vim tias nws muab cov kev faib tawm zoo, kev nplij siab, thiab kav ntev.
Ib yam li ntawd, polyurethane ua npuas ncauj tau siv dav hauv cov khoom siv xws li lub txaj, hauv ncoo, cov rooj zaum hauv chaw ua haujlwm, thiab cov khoom siv kev nyab xeeb rau menyuam yaus.
Qhov tseem ceeb yog xaiv cov ntaub ntawv uas tsim los rau daim ntawv thov thiab ua raws li cov qauv kev lag luam.
Yuav Ua Li Cas Xaiv Cov Khoom Zoo PU Ua Npuas Ncauj
Yog tias koj tab tom yuav cov khoom lag luam polyurethane ua npuas ncauj rau kev lag luam lossis kev lag luam, xav txog cov hauv qab no:
Ua haujlwm nrog cov chaw tsim khoom muaj kev paub zoo uas tswj xyuas kev tswj xyuas zoo.
Thov cov ntaub ntawv pov thawj thiab cov ntaub ntawv ua raws cai.
Paub meej tias cov khoom tau kho tag nrho ua ntej xa khoom.
Tshawb xyuas seb VOC lossis kev ntsuas emission puas muaj yog tias koj xav tau los ntawm koj lub khw.
Xaiv cov qauv tsim ua npuas ncauj raws li cov khoom tsim ib puag ncig thiab kev ua tau zoo.
Ib tus neeg muag khoom ntseeg siab yuav tsum muaj peev xwm muab kev txhawb nqa nrog rau cov ntaub ntawv qhia txog cov khoom lag luam zoo thiab kev ua raws cai.
Cov kev xav tsis zoo txog PU Foam
Ib qho kev nkag siab tsis zoo yog tias tag nrho cov polyurethane ua npuas ncauj yog tshuaj lom vim tias cov tshuaj reactive koom nrog thaum tsim khoom.
Hauv kev muaj tiag, cov khoom siv raw siv hauv kev tsim khoom yog qhov txawv ntawm cov ua npuas ncauj tiav. Thaum cov tshuaj tiv thaiv ua tiav thiab cov khoom tau kho tag nrho, polyurethane dhau los ua cov khoom ruaj khov haum rau ntau yam kev lag luam thiab cov neeg siv khoom siv.
Lwm qhov kev xav tsis zoo yog tias tag nrho cov khoom lag luam polyurethane tso cov pa phem tsis tu ncua. Thaum cov khoom tsim tawm tshiab tuaj yeem muaj cov ntxhiab tsw ib ntus, ua kom zoo PU ua npuas ncauj tsis tu ncua emissions phom sij nyob rau hauv ib txwm siv tej yam kev mob.
Xaus
PU ua npuas ncauj tsis muaj tshuaj lom thaum nws tau raug tsim thiab kho kom zoo. Thaum cov khoom siv raw siv thaum lub sijhawm tsim khoom yuav tsum tau ua tib zoo tuav, cov khoom tiav tau lees paub dav rau nws txoj kev nyab xeeb, ruaj khov, thiab ntau yam thoob plaws ntau qhov kev lag luam.
Rau cov neeg yuav khoom, cov kev txiav txim siab tseem ceeb tshaj plaws yog xaiv cov chaw tsim khoom muaj npe nrov, thov cov ntaub ntawv ua raws li kev cai, thiab xaiv cov qauv polyurethane uas haum rau daim ntawv thov. Los ntawm kev ua li ntawd, kev lag luam tuaj yeem ua kom cov khoom ua tau zoo thiab cov neeg siv kev nyab xeeb.
