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 lag luam nyob rau hauv lub 80 tsaus ntuj los nthuav tawm cov khoom siv hluav taws xob ntxiv ...... Nrog kev ua haujlwm txuas ntxiv ntawm cov pa roj mpastomer ppa. Maj mam nyob ib txoj haujlwm tseem ceeb heev hauv kev ua cov yeeb yaj kiab, cov hlab, hoses, cables, thiab lwm thaj teb.
Lub pfas (perfluoro thiab polyfluoroyls) kev txwv tawm, lub teb chaws Yelemees, Finland, tau xa mus rau lub Ib Hlis 13, 2023, nrog lub homphiaj, tau xa mus rau lub sijhawm tso tawm hauv ib puag ncig thiab Ua cov khoom lag luam thiab cov txheej txheem kev nyab xeeb dua los ntawm kev siv tshuaj tsw qab (pfas) thiab polyfredorined carbon thiab kwv yees kom muaj 10,000 molecules nyob rau hauv tag nrho), suav nrog cov lus fluoropolymers. (Pfas), suav nrog cov lus pom fluoropolymers. Cov Tswvcuab Lub Xeev yuav pov npav rau hauv kev txiav tawm hauv 2025. Kev siv tshuaj fluoropolymers tshwj tsis yog rau cov khoom siv tshuaj fluoropolymers tsuas yog siv cov khoom siv kho mob, cov khoom siv tau zaub mov, roj cell, lwm yam, thiab muaj kev cuam tshuam loj heev rau qhov chaw ecology ntawm tag nrho cov saw hlau.
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 siv rau tib qho kev ua tau zoo ib yam li fluorine-dawb-muaj Additive nyob rau hauv qhov extrusion ntawm xaim thiab cabing, thiab zaj duab xis, thiab ib qho me me ntawm cov kev ua kom zoo thiab cov yam ntxwv saum npoo ntawm cov plastics ua 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!
