Ngabe ipuleti lensimbi elinemibala lifinyelela kanjani ukulwa nokugqwala? Ipuleti lensimbi elinamekwe ngombala, elibuye laziwe ngokuthi ipuleti lensimbi elinamekwe ngombala, liwumphumela wesenzo esihlanganisiwe sokumboza, isendlalelo sokwelashwa kwangaphambilini, i-primer, nejazi eliphezulu. Siyibiza ngokuthi "uhlelo olune-anti-corrosion olulodwa lwepuleti lensimbi elihlanganiswe ngombala". Ibhodi lethu elihlanganiswe ngombala lenziwe ngemikhiqizo ehlukahlukene yokugcotshwa futhi lihlanganiswe ngezigaba ezi-5 nezinqubo ezingama-48, ezinezakhiwo ezinhle kakhulu zokulwa nokugqwala.
Ukumelana nokugqwala kanye nokumelana nokufiphala okuhlala isikhathi eside.

Siyithola kanjani i-anti-corrosion yamapuleti ensimbi ahlanganiswe ngombala? Ipuleti lensimbi elinamekwe ngombala, elibuye laziwe ngokuthi ipuleti lensimbi elinamekwe ngombala, liwumphumela wesenzo esihlanganisiwe sokumboza, isendlalelo sokwelashwa kwangaphambilini, i-primer, nejazi eliphezulu. Siyibiza ngokuthi "uhlelo olune-anti-corrosion olulodwa lwepuleti lensimbi elihlanganiswe ngombala".
Ukufakwa kwepuleti lensimbi lombala kudlala indima yomhlatshelo yokulwa nokugqwala. Kalula nje, inweba impilo yesevisi yepuleti lensimbi ngokuqhubeka lisebenzisa ukunamathela kwayo. Yiqiniso, uhlobo, ikhwalithi, kanye nokuqina kwe-coating yizici ezibalulekile ebude besikhathi sokusetshenziswa kokugqoka. Amapuleti ethu ensimbi ahlanganiswe ngombala ikakhulukazi asebenzisa i-galvanized, i-aluminium zinc, i-aluminium galvanized magnesium nezinye izingcwecwe zensimbi ezinamekwe ezivela ezitshalweni ezinkulu zensimbi zasekhaya, ezinamandla aphezulu kanye nokumelana nokugqwala okungcono.
Ake sikhulume ngongqimba lwangaphambi kokwelashwa futhi. Lena yingxenye ebalulekile yokunqanda ukubola kwamapuleti ensimbi anombala, okuvame ukunganakwa. Isendlalelo sokwelashwa kwangaphambili, okwaziwa nangokuthi ungqimba lwe-passivation, ludinga ukusetshenziswa kwezixazululo ze-passivation ezifana ne-phosphate noma i-chromate ukuze kudlule indawo engaphansi ngaphambi kokumbozwa kombala. Lokhu akugcini nje ukwandisa ukunamathela kokugqoka, kodwa futhi kudlala indima ekuphikiseni ukugqwala. Ucwaningo selukhombisile ukuthi ocwaningweni lokungamelani nesifutho sikasawoti esingathathi hlangothi samapuleti afakwe umbala, izinga lomnikelo wekhwalithi yongqimba lwangaphambi kokwelashwa lifinyelela ngaphezu kwama-60%.
Ake sikhulume nge-primer futhi. Ngakolunye uhlangothi, i-primer idlala indima ekwandiseni ukunamathela kokugqoka. Ngemuva kokuthi ifilimu yepende ikwazi ukungena, ngeke isuke ekugqokeni, ivimbele ama-blistering kanye ne-detachment of the coating. Ngakolunye uhlangothi, ngenxa yobukhona bemibala ekhishwa kancane njengama-chromates ku-primer, ingadlula i-anode futhi ithuthukise ukumelana nokugqwala kwentolo.

Ekugcineni, ake sikhulume nge-topcoat. Ngaphezu kobuhle, i-topcoat ikakhulukazi isebenza ukuvimba ukukhanya kwelanga futhi ivimbele ukulimala kwe-UV enamathela. Ngemuva kokuthi ijazi langaphezulu lifinyelele ukushuba okuthile, linganciphisa ukukhiqizwa kwama-micropores, ngaleyo ndlela livikele ukungena kwemithombo yezindaba ezonakalisayo, linciphise ukungena kwamanzi nomoya-mpilo wento enamathelayo, futhi livimbele ukugqwala kokumboza. Ukumelana ne-UV kanye nokuminyana kwezingubo ezihlukene kuyahlukahluka, futhi ohlotsheni olufanayo lokunamathela, ukushuba kwefilimu kapende kuyisici esiyinhloko esithinta ukugqwala. Amabhodi ethu ahlanganiswe ngombala enziwa ngokukhetha izinhlobo ezihlukahlukene zezingubo ezilashwe emazingeni okushisa aphezulu, okuholela ekumelaneni nokugqwala okuphakeme nokusebenza okuhlala isikhathi eside kokubola.
