Iyini i-Epoxy Coatings

Izembatho ezisekelwe ku-epoxy zingaba izinhlelo ezinezingxenye ezimbili (eziphinde zibizwe ngezingxenye ezimbili ze-epoxy coating) noma zisetshenziswe njenge i-powder coating. Izingxenye ezimbili ze-epoxy coatings zisetshenziselwa izinhlelo zokusebenza eziphezulu ku-substrate yensimbi. Ziyindlela enhle yokuhlanganisa ukwakheka kokumboza ngempushana ezinhlelweni zezimboni nezimoto ngenxa yokuguquguquka okuphansi kwazo kanye nokuhambisana nokwakheka kwamanzi. I-epoxy powder coating isetshenziswa kakhulu ekuhlanganisweni kwensimbi ezinhlelweni "zezimpahla ezimhlophe" njengezifudumezi namaphaneli ezinto zikagesi ezinkulu. I-epoxy coating nayo isetshenziselwa kabanzi ukuvikela ukugqwala kwamapayipi nokufakwa: embonini kawoyela negesi, kodwa futhi kumapayipi amanzi, ukhonkolo oqinisa i-rebar ukubiza ezimbalwa.

I-epoxy iyi-copolymer etholakala ngokuphindaphinda kwe-epoxide (resin) nge-polyamine (hardener). Baziwa kakhulu ngezinga labo eliphezulu lokunamathela, ikakhulukazi ensimbi, ukumelana namakhemikhali aphezulu kanye nokushisa, nekhono elihle kakhulu lokuhlukanisa ugesi. Ngakho-ke ukwakheka kwe-epoxy kuyisixazululo esikhethwayo sezingxenye eziningi zikagesi nezinto zikagesi (isb: ukufakwa ikhoyili, imaski ye-solder kumabhodi esekethe). KudluleralIzingubo ze-epoxy zibiza kakhulu kunezinye izinhlelo ezifana ne-Alkyd noma i-Acrylic, kodwa futhi zibonisa ukusebenza okuphezulu. Ngakolunye uhlangothi, i-epoxy coatings ihlale ihlushwa imishayo ye-UV. Lobu buthakathaka bunxeshezelwa ngokusebenzisa isendlalelo esivikela i-UV noma ijazi eliphezulu
