Tam sim no epoxydaim ntawvntawm kev ua lag luam tuaj yeem muab faib ua halogen-dawb thiab halogen-free.The halogen epoxydaim ntawvyog ntxiv nrog fluorine, chlorine, bromine, iodine, astatine thiab lwm yam halogen ntsiab los ua lub luag hauj lwm nyob rau hauv nplaim hluav taws.Txawm hais tias lub halogen lub ntsiab yog nplaim retardant, nyob rau hauv cov ntaub ntawv nws yog kub hnyiab, nws yuav tso tawm ib tug ntau ntawm toxic gases, xws li dioxins. , benzofurans, thiab lwm yam., nrog hnyav saj thiab cov pa luam yeeb tuab, nws yooj yim ua rau mob qog noj ntshav thaum nws nkag mus rau tib neeg lub cev thiab ua phem rau lub neej thiab kev noj qab haus huv.
Halogen-dawb epoxydaim ntawvTxhawm rau kom ua tiav cov txiaj ntsig ntawm cov nplaim hluav taws xob, qhov sib ntxiv tseem ceeb yog phosphorus nitrogen caij.Thaum cov phosphorous resin raug hlawv, nws yog rhuab thiab decomposed los ua polyphosphoric acid.Poly phosphoric acid tuaj yeem tsim ib txheej ntawm cov yeeb yaj kiab tiv thaiv ntawm qhov chaw. ntawm epoxy phaj, muab xaus rau kev sib cuag ncaj qha nrog huab cua, tsis muaj oxygen txaus, hluav taws yog ib txwm tua.Thiab cov phosphorus-muaj resin nyob rau hauv lub combustion yuav tsim incombustible gas, ntxiv mus cuag cov nyhuv ntawm nplaim retardant.
Ntxiv nrog rau kev ua tus phooj ywg environmentally thiab nplaim retardant,epoxy tsis muaj halogendaim ntawvmuaj ntau lwm yam zoo.Nws yog feem ntau siv raws li ib tugcov khoom siv insulating, yog li cov rwb thaiv tsev ua tau zoo heev.Nws tuaj yeem ua lub luag haujlwm ntawm kev txhawb nqa thiab rwb thaiv tsev ntawm ntau yam khoom siv hluav taws xob, hauv qhov chaw hnyav, xws li av noo, kub kub, tab sis kuj tuaj yeem ua haujlwm ib txwm. stability, ua tsaug rau cov nitrogen thiab phosphorus ntsiab, lub peev xwm ntawm nitrogen thiab phosphorus resin molecules txav thaum rhuab. Tsis tas li ntawd, nws tsis nqus dej, muaj zog yooj thiab lwm yam zoo.
Raws li thaum ntxov li ob peb xyoos dhau los, European Union tau txwv tsis pub siv halogen-dawb epoxy nplooj ntawv, tab sis vim yog tus nqi siab ntawm halogen-dawb epoxy.nplooj ntawv, nws tsis tau siv dav hauv Suav teb, thiab ntau lub tuam txhab tseem siv halogen epoxydaim ntawvs. Nrog rau kev txhim kho ntawm Tuam Tshoj txoj kev lag luam thiab kev txhim kho ntawm tib neeg kev paub txog kev tiv thaiv ib puag ncig, kev ua tau zoo ntawm halogen-dawb epoxy board tau txais txiaj ntsig zoo los ntawm cov neeg.Kuv ntseeg hais tias nyob rau hauv lub neej yav tom ntej, nws yeej yuav nrov.
