Lwm cov kev daws teeb meem rau PPA nyob rau hauv Pfas kev txwv
PPA (polymer ua ntxiv) uas yog fluoropolymer ua kev pabcuam, ua kom cov fluoropolymer cov qauv kev ua tau zoo, txhim kho cov shoarchskin tuag, txhim kho cov sharkskin, thiab lwm yam. Nws yog thawj zaug tsim los ntawm Dupont nyob rau xyoo 1961 thiab muab tso rau hauv kev ua haujlwm ntawm cov tshuab, PPA txuas ntxiv rau cov tshuaj lom neeg ntxiv rau hauv kev ua yeeb yam ...... Nrog rau kev ua yeeb yam zoo tshaj plaws ...
Lub pfas (perfluoro thiab polyfrookyl tshuaj) cov lus thov kev txwv, Finland, thiab Sweden, tau xa mus rau hauv lub Ib Hlis 13, tau xa mus rau hauv lub Ib Hlis 13, tau xa mus rau hauv lub Ib Hlis 13, 2023, nrog rau kev txo cov khoom lag luam thiab cov txheej txheem sib luag Cov tshuaj (PFAs) uas muaj tsawg kawg ib qho perfluorinated carbon atom (kwv yees yuav yog 10,000 molecules nyob rau hauv tag nrho), suav nrog cov lus fluoropolymers. (Pfas), suav nrog cov lus pom fluoropolymers. Cov Tswv Cuab Lub Ntsiab Lus yuav pov npav rau ntawm kev txiav tawm hauv 2025. Kev siv tshuaj tua kab mob zoo li PTFE, txwv tsis pub siv cov ntaub ntawv fluoropolymers tshwj tsis yog siv cov ecology ntawm tag nrho cov saw.
Hauv kev teb, silike tau qhia aFluorine-pub dawbrau fluorine-raws PPA --APfas-dawb polymer ua pab (PPA)Cov. NoFluorine-dawb ppa mb, PTFE-dawb additive yog ib qho kev hloov kho polysiloxane masterbatch uas muaj kev sib cav sib ceg thiab ua yeeb yaj kiab, thiab ib qho me me ntawm qhov no cov khoom lag luam zoo ntxiv tau txhim kho lub resin Fosicity thiab txheej txheem, ntxiv rau lubrication thiab cov yam ntxwv saum npoo ntawm cov plastics tau extruded. Qhov sib ntxiv ntawm cov nyiaj me me tuaj yeem txhim kho cov neeg cov neeg uas muaj zog, muaj txiaj ntsig thaum lub ntiaj teb cov khoom siv thiab cov ntiaj chaw thaum nce ntau lawm thiab khoom lag luam zoo.
Silike Fluorine-Free PPA MB, Pfas-dawb ppa, thiabPTFE-dawbCov khoom ntxiv tuaj yeem hloov kho fluorine ppa masterbatch, ppa mb, fluoropolymer, fluorine raws li cov yeeb yaj kiab yas, cov xaim, xaim ... thiab lwm yam.
Raug ua yeeb yam:
Txhim kho kev ua kom haum thiab tshuaj ntsuab ua tiav;
Txo cov torque thiab khoom siv;
Txo cov quav tuag thiab txhim kho shark daim tawv nqaij tshwm sim.
Hu rau Silike thiab tau txais kojPTFE Lwm txoj kev daws teeb meem!
