Tsopano epoxypepalapa msika akhoza kugawidwa mu halogen-free ndi halogen-free.The halogen epoxypepalaimawonjezeredwa ndi fluorine, chlorine, bromine, ayodini, astatine ndi zinthu zina za halogen kuti zithandize kuchepetsa moto wamoto.

Epoxy wopanda halogenpepala, kuti tikwaniritse zotsatira za lawi retardant, Kuwonjezera waukulu ndi phosphorous chigawo nayitrogeni element.Pamene phosphorous utomoni kuwotchedwa, ndi mkangano ndi decomposed kupanga polyphosphoric acid.Poly phosphoric asidi akhoza kupanga wosanjikiza woteteza filimu pamwamba pa mbale epoxy, kuthetsa mwachindunji kukhudzana ndi mpweya, palibe zachilengedwe zozimitsa moto-phosphorous. mu kuyaka adzatulutsa mpweya incombustible, zina kukwaniritsa zotsatira za lawi retardant.

Kuwonjezera pa kukhala wochezeka ndi chilengedwe komanso kuletsa moto,epoxy wopanda halogenpepalakukhala ndi zabwino zina zambiri. Nthawi zambiri amagwiritsidwa ntchito ngatizipangizo zotetezera, kotero ntchito kutchinjiriza ntchito zabwino kwambiri.Ikhoza kuchita mbali ya thandizo ndi kutchinjiriza mbali zosiyanasiyana pakompyuta, m'malo nkhanza, monga chinyezi, kutentha kwambiri, komanso ntchito normally.Halogen-free epoxy mapepala amakhalanso wabwino matenthedwe bata, chifukwa nayitrogeni ndi phosphorous zinthu, luso nayitrogeni ndi phosphorous utomoni mamolekyu kusuntha pamene kutenthedwa, ubwino si kusinthasintha madzi.

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.
