Indlela khetha ibhodi le-epoxy fiberglass?

Ibhodi le-epoxy glass fiber emakethe ngokuvamile lihlukaniswe: 3240 epoxy glass fiber board kanye ne-FR4 epoxy glass fiber board.

Uma sithenga, kuzoba nomehluko phakathi kwe-halogen-free kanye ne-halogen-free, ngakho-ke yiziphi izakhi ze-halogen ezisetshenziswa ku-epoxy glass fiberboard? Uyini umehluko phakathi kwe-halogen-free kanye ne-halogen-free? Kufanele sikhethe kanjani lapho sithenga?

Ake siqale sikhulume ngokuthi iyini i-halogen? Iyini indima yawo?

Izakhi ze-halogen ezishiwo lapha zibhekisela ku-fluorine, i-chlorine, i-bromine, i-iodine, ne-astatine. Angadlala umphumela wokunqanda ilangabi, kodwa anobuthi. Uma zisha, zizokhipha amagesi ayingozi njengama-dioxin nama-benzofuran. , Iphinde ibe nentuthu enzima nephunga, okulula ukuyibangela umdlavuza kanye nokulimala okukhulu. Kuphinde kwadala ingozi embi emvelweni.

Njengoba izakhi ze-halogen ziyingozi, kungani abantu abaningi kangaka bekhetha lolu hlobo lwento? Yiqiniso, into ebaluleke kakhulu intengo. Nakuba i-halogen-free inhle kuzo zonke izici, intengo ibiza kancane. Kepha awukho umehluko obalulekile phakathi kwe-halogen-free kanye ne-halogen-free.

Ngenxa yokuthi i-halogen-free epoxy glass fiber board yengezwe nge-phosphorus, i-nitrogen nezinye izakhi, ingadlala nomphumela wokunqanda ilangabi. Lapho i-resin equkethe i-phosphorus ivutha, izobola ibe yi-metaphosphoric acid ngokushisa ukuze yakhe ifilimu evikelayo, evimbela ibhodi le-epoxy glass fiber ukuthi lingathintani nomoya. , Ngaphandle komoya-mpilo owanele, izimo zokuvutha azikwazi ukufinyelelwa, futhi ilangabi lizicisha ngokwalo. Kodwa i-halogen-free ihambisana kakhulu nemvelo futhi isiza kakhulu ekuthuthukisweni kwesikhathi esizayo kwezinto zokuvikela.

Akukhona lokho kuphela, ibhodi ye-halogen-free epoxy glass fiber board inezinzuzo eziningi njengokumelana nomswakama, ukumelana nokushisa okuphezulu, nokusebenza okushisayo okuzinzile. Ingasetshenziswa endaweni enomswakama, ngisho noma uthinte amakhemikhali ngephutha, akudingeki ukhathazeke ngokugqwala. Kodwa-ke, ngenxa yentengo ephezulu ye-halogen-free epoxy glass fiber board, ivinjelwe. Kodwa-ke, ngokuthuthukiswa kobuchwepheshe kanye nokuthuthukiswa kwezinto zokufakelwa, sikholelwa ukuthi leli bhodi elinobungani bemvelo lizokhuthazwa kabanzi.
