iketanga lensimbi elinamandla lilungele iphrojekthi yakho
Iketango lensimbi elikhangayo liwukusabela kwensimbi encibilikisiwe kanye ne-iron matrix ukukhiqiza ungqimba lwengxubevange, ukuze i-matrix ne-coating kuhlanganiswe.Iketanga lensimbi eliphehliwe liyiketango lokuqala lokuqoqwa, ukuze kukhishwe i-iron oxide ebusweni beketango, ngemuva kokukhetha, nge-ammonium chloride noma i-zinc chloride isixazululo samanzi noma i-ammonium chloride kanye ne-zinc chloride exutshwe nethangi lesisombululo samanzi sokuhlanza, bese kuthi ethangini lokucwilisa elishisayo.Iketanga lensimbi eliphehliwe linezinzuzo zokuhlanganisa umfaniswano, ukunamathela okuqinile nempilo ende yesevisi.
Iketango lensimbi eliphehliwe liyidiphu elishisayo eliphehliwe ngesisekelo seketanga lensimbi elishiselwe (okungukuthi, i-zinc iyancibilika ebhodweni le-zinc, bese iketango licwiliswa ku-zinc ewuketshezi isikhathi eside ukuze likhiphe, bese lipholisa futhi limiswe. ).
Izindonga zangaphakathi nezangaphandle zeketango zinesendlalelo se-zinc esinamathiselwe ngesikhathi esifanayo.Amaketanga ensimbi asetshenziswa ngokuvamile ukudlulisa uketshezi olunomfutho ophansi (okungukuthi, amanzi, igesi ewuketshezi).
Izakhiwo ezingokomzimba zamaketanga avamile namaketanga anathayela ziyafana, kodwa ngenxa yokuthi ukumbozwa kwendawo kuhlukile, ukumelana nokugqwala kwawo akufani ncamashi.
Eyodwa, iketango elivamile: i-chromium iyinsimbi yombala wesiliva, izinzile kakhulu emkhathini, ngisho naku-alkali, i-nitric acid, i-sulfide, isisombululo se-carbonate nayo ingagcina isimo esizinzile.I-Chrome inokwakheka okuqinile, ukumelana nokugqokwa okuqinile, futhi ingagcina ukucwebezela kwayo isikhathi eside.Ububi be-chromium plating ukuthi ayivikeli isisekelo sensimbi ekugqwaleni.Ngakho-ke kwandulelwa ukugqoka kwethusi noma i-copper-tin alloy ebopha kahle ensimbi eyisisekelo.Ngokuvamile, i-chrome-plated chain inezici zezindleko eziphakeme kancane, izimoto zasekhaya ezisezingeni eliphezulu, izimoto eziphathwayo ikakhulukazi nazo, ngokuvamile ezinganconywa ukuthi zisetshenziswe.
Okubili, iketango likathayela: ukubukeka kweketango eliwuthayela lombala oluhlaza.Lokho kuwumphumela wokwehliswa kwe-zinc enamathela okulandelwa ukufiphala.I-zinc coating ishintsha kancane emoyeni owomile.Emoyeni onomswakama, emanzini aqukethe i-carbon dioxide nomoya-mpilo, indawo yayo yakha ifilimu elincanyana le-zinc carbonate eyisisekelo.Le filimu inomphumela wokuvimbela ukugqwala.Ingavimbela ukugqwala okwengeziwe kwensimbi.Siyabona ukuthi amanye amaketanga anathayela ashintsha asuka kwabamhlophe abe nsundu ngokushesha ngemva kokusetshenziswa, kodwa alukho ushintsho olukhulu ngemva kwalokhu, isizathu siwukuthi.
Uma kuqhathaniswa namaketanga avamile, amaketanga othayela ekukhiqizeni nasekucutshungulweni ngemva kokwelashwa okukhethekile kwama-galvanized, ekusetshenzisweni kwezici ezinhle kakhulu, ukuze kungakhathaliseki ukuthi kusukela empilweni yomkhiqizo noma ukusetshenziswa kwangempela kwalokhu okungenhla kunamazinga ahlukene okuthuthukisa.Inqubo ye-galvanized ilula, izindleko ziphansi, ngakho-ke uhlobo olujwayelekile, ibhayisikili elisindayo lisetshenziswa nalo.
