Yintoni i-Epoxy Coatings

Iingubo ezisekelwe kwi-epoxy zinokuba ziinkqubo zamacandelo amabini (ezikwabizwa ngokuba ziinxalenye ezimbini zokwaleka kwe-epoxy) okanye zisetyenziswe njengendawo yokwaleka. yengubo. Iingubo ezimbini ze-epoxy zisetyenziselwa iinkqubo zokusebenza eziphezulu kwi-metal substrate. Ziyeyona ndlela ilungileyo yokwakheka komgubo kwimizi-mveliso kunye nezicelo zeemoto ngenxa yokuguquguquka okuphantsi kwazo kunye nokuhambelana nokuqulunqwa kwamanzi. I-epoxy powder isetyenziselwa ukugquma ngesinyithi kwiinkqubo "zempahla emhlophe" njengezifudumezi kunye neepaneli zezixhobo ezinkulu. I-epoxy coating nayo isetyenziselwa ukhuseleko lomhlwa lwemibhobho kunye nokufakelwa: kwishishini leoli kunye negesi, kodwa nakwimibhobho yamanzi, i-concrete yokuqinisa i-rebar ukubiza ezimbalwa.

I-epoxy yi-copolymer efunyenwe ngokuxutywa kwe-epoxide (i-resin) kunye ne-polyamine (i-hardener). Baziwa kakhulu ngezinga labo eliphezulu lokuncamathelisa, ngakumbi kwintsimbi, imichiza ephezulu kunye nokumelana ne-thermal, kunye nobuchule obugqwesileyo bokufakelwa kombane. I-epoxy formulations ngoko ke isisombululo esikhethiweyo kuninzi lwamalungu ombane kunye ne-electronics (umzekelo: i-coil coil, i-solder mask kwiibhodi zesekethe). OveralIingubo ze-epoxy zibiza kakhulu kunezinye iinkqubo ezifana ne-Alkyd okanye i-Acrylic, kodwa nazo zibonisa ukusebenza okuphezulu. Kwelinye icala, iingubo ze-epoxy zihlala zihlupheka ngenxa yemitha ye-UV. Obu buthathaka bubuyekezwa ngokusetyenziswa kwe-UV ekhuselayo okanye i-topcoat
