Amathangi Ensimbi Eboshwe Nge-Epoxy Ukuvikelwa Kwe-Fbe Emanzini Namanzi Angcolile
Amathangi ensimbi ane-epoxy coated asetshenziswa emanzini nasezinsizeni zamanzi asebenzisa i-fusion bonded epoxy efakwa njenge-electrostatic powder futhi yelashwe cishe ku-200 kuya ku-230 °C. Ifilimu yakheka ibe ngu-180 kuya ku-280 µm, ifaneleka ku-AWWA C550, futhi isidlule ukuhlolwa kwe-salt spray ngaphezu kwamahora angu-4000. Ngenxa yokuthi i-powder iyancibilika futhi ihlangane ibe ifilimu eqhubekayo ebambelela ensimbini elungisiwe kunokuba ihleli phezu kwayo, ithangi eline-FBE lining alinayo ingqimba ye-solvent engangena kuyo futhi alinayo indlela yokugqwala engaphansi kwe-coating. Ifilimu ihlanganisa ububanzi be-pH, ibhekana ne-asidi ne-alkali ezishintshanayo, futhi ihlolwa endaweni ngokutholwa kwe-holiday nangokuhlolwa kokunamathela kwe-pull-off ngaphambi kokuba ithangi ligqitshwe noma ligcwaliswe.
Ukugcinwa kwamanzi angcolile kujezisa ama-coatings ukuze aphile. Amanzi anolaka, i-chemistry iyashintsha ngokushintsha kwesikhathi, ithangi ligcwaliswa futhi lihlanjululwe njalo, futhi ingaphakathi lihlala linomswakama isikhathi esiningi sonyaka. I-coating yegobolondo elipendwe iyaphela phakathi neminyaka embalwa, futhi ukulungisa kusho ukukhipha umkhumbi ekusebenzeni ukuze uqhumise futhi upende kabusha ingaphakathi. I-fusion bonded epoxy ikhona ukuze isuse lowo mjikelezo. Lapho onjiniyela beqhathanisa amathangi ensimbi ane-epoxy coated anokuvikelwa kwe-FBE nama-glass-fused-to-steel ethangini lamanzi noma lamanzi angcolile, isinqumo simayelana ne-coating mechanism kanye ne-interface, hhayi ukuthi iyiphi ifilimu ebukeka kangcono kushadi lemibala. Ukucabanga okufanayo kusetshenziswa kumathangi ensimbi ane-epoxy coated anokuvikelwa kwe-FBE kumanzi namanzi angcolile, lapho i-powder ifakwa ensimbini elungisiwe ku-200 kuya ku-230 °C ukuze kwakhiwe ifilimu. Le ndatshana ihlanganisa ubuchwepheshe be-coating, ukuhlolwa okukufakazelayo, nokuthi kuhambisana kuphi embonini yamanzi namanzi angcolile.
Indlela i-fusion bonded epoxy esetshenziswa ngayo
I-powder, i-electrostatic charge, kanye ne-heat cure yikho okwenza umehluko. I-epoxy powder ifafazwa nge-electrostatic phezu kwensimbi esihlanjululwe futhi elungiselelwe ngomshini, bese iphaneli idlula ku-cure oven cishe ku-200 kuya ku-230 °C. I-powder iyancibilika, igeleze futhi ixhumane ibe ifilimu eqhubekayo, yingakho ibizwa nge-fusion bonded. Ukujiya kwefilimu kuphaneli yethangi ngokuvamile kuba ngu-180 kuya ku-280 µm. Akukho solvent, akukho primer coat elindele ukuphazanyiswa, futhi akukho wet edge engalimala ngaphambi kwempelasonto. Okutholayo esikhundleni salokho ifilimu ebambelela ku-substrate elungiselelwe, ngokunamathela okukalwa nge-megapascal ambalwa ngokuhlolwa kwe-pull-off, kanti ukutholwa kwe-holiday kusetshenziselwa ukuthola izimbobo ezincane ngaphambi kokuba ithangi liqale ukusebenza.
