Ukufafaza nge-zinc kubhekisela kubuchwepheshe bokwelapha obungaphezulu bokunamathisela ungqimba lwezinc phezu kwensimbi, ingxubevange noma impahla yayo ebanzi ukuze kudlale indima yobuhle nokuvimbela ukugqwala.Indlela eyinhloko esetshenziswayo i-hot dip galvanizing.
Ngakho-ke uyini umphumela wokufafaza kwe-zinc epayipini lensimbi elomile le-nodular cast iron?
Ngenxa yokuqukethwe kwekhabhoni ephezulu ye-iron cast, ama-alloys e-iron-carbon agqwala ngokushesha kakhulu ezimeni ezimanzi.Uma ubheka insimbi yengulube endaweni etholakala kuyo, nakanjani izogqwala ngaphandle.I-Zinc isebenza kakhulu ngamakhemikhali kune-ayoni nethusi, ngakho ukunameka insimbi nge-zinc kungayivikela ekugqwaleni.Le nqubo isetshenziswa ikakhulukazi embonini yokwakha neyokwakha imikhumbi, lapho ukusabela kwamakhemikhali kwenzeka lapho insimbi ihlanganiswe ne-zinc, emboza insimbi ngongqimba oluyisivikelo lwe-ZnC03, 3Zn (OH) 2 nokunye okunjalo.Yehlisa ukugqwala kwangaphandle ukuze zome.
Ingqimba ye-Zinc idlala indima ebaluleke kakhulu ekusebenzeni kwe-anticorrosion: ngakolunye uhlangothi, ukwakheka kwefilimu yokuzivikela eminyene engancibiliki exhunywe odongeni lweshubhu, kunganciphisa kakhulu ukugqwala kwe-electrochemical kanye ne-microbial;Ngakolunye uhlangothi, i-zinc yensimbi nayo inokumelana nomthelela wekhono le-deformation yepulasitiki, iqinise ukuvikelwa kwepayipi.Ikhono le-Zinc + asphalt anti-corrosion libonakala futhi ekusebenzelaneni phakathi kwalokhu okubili: phakathi kwe-zinc ne-cast iron naphakathi kwe-zinc ne-asphalt inokunamathela okuhle, epayipini nasemhlabeni wangaphandle ukuze kwakhiwe umgoqo ophelele wokuzivikela, futhi kuvimbele i-anti- ukwehluleka ukugqwala.
