Tsopano epoxypepalapa msika akhoza kugawidwa mu halogen-free ndi halogen-free.The halogen epoxypepalaimawonjezeredwa ndi fluorine, klorini, bromine, ayodini, astatine ndi zinthu zina za halogen kuti zithandize kuchepetsa moto wamoto. , benzofurans, etc., ndi kukoma kolemera ndi utsi wandiweyani, n'zosavuta kuyambitsa khansa ikalowa m'thupi la munthu ndikuwopseza kwambiri moyo ndi thanzi.

Epoxy wopanda halogenpepala, pofuna kukwaniritsa zotsatira za moto woyaka moto, chowonjezera chachikulu ndi phosphorous element nitrogen element.Pamene utomoni wa phosphorous watenthedwa, umatenthedwa ndikuwonongeka kuti ukhale wa polyphosphoric acid.Poly phosphoric acid ikhoza kupanga filimu yotetezera pamwamba. wa mbale ya epoxy, kuthetsa kukhudzana mwachindunji ndi mpweya, palibe mpweya wokwanira, moto umazimitsidwa mwachibadwa.Ndipo utomoni wokhala ndi phosphorous mu kuyaka udzatulutsa mpweya wosayaka, komanso kukwaniritsa zotsatira za kutentha kwa moto.

Kuwonjezera pa kukhala wochezeka ndi chilengedwe komanso kuletsa moto,epoxy wopanda halogenpepalakukhala ndi maubwino ena ambiri.Nthawi zambiri amagwiritsidwa ntchito ngatizipangizo zotetezera, kotero kuti ntchito yotsekemera ndi yabwino kwambiri.Ikhoza kugwira ntchito yothandizira ndi kutsekemera kwa zipangizo zosiyanasiyana zamagetsi, m'malo ovuta, monga chinyezi, kutentha kwambiri, komanso kugwira ntchito bwino. kukhazikika, chifukwa cha zinthu za nayitrogeni ndi phosphorous, kuthekera kwa mamolekyu a nayitrogeni ndi phosphorous resin kusuntha akatenthedwa.

Zaka zingapo zapitazo, European Union yaletsa kugwiritsa ntchito mapepala a epoxy opanda halogen, koma chifukwa cha kukwera mtengo kwa halogen-free epoxy.mapepala, sichinagwiritsidwe ntchito kwambiri ku China, ndipo opanga ambiri akugwiritsabe ntchito halogen epoxypepalas.Ndi chitukuko cha chuma cha China ndi kusintha kwa kuzindikira kwa anthu za chitetezo cha chilengedwe, ntchito yabwino ya halogen-free epoxy board yalandiridwa bwino ndi anthu.Ndikukhulupirira kuti posachedwa, idzakhala yotchuka.
