Benziwa kanjani ababhali bobunjiniyela?

Izinto zokwakha
	Ithiphu yokumaka Kunezinhlobo ezine zezinto ezisetshenziselwa ukwenza amathiphu ombhali wobunjiniyela: insimbi eqinile, insimbi yamathuluzi, i-tungsten carbide, nensimbi enamachopho edayimane. Umzimba wokumaka Umzimba wombhali wobunjiniyela ungenziwa ngezinto ezimbalwa, ezivame kakhulu insimbi noma i-aluminium. Ababhali abanemizimba yensimbi bane-nickel-plated ukumelana nokugqwala, kuyilapho imizimba ye-aluminium ingenziwa i-anodized, nakuba lokhu ikakhulukazi okobuhle. Abanye ababhali abangabizi kakhulu banomzimba wepulasitiki we-PVC.
Ukwelashwa kokushisa
	Ukwelashwa kokushisa nokushisa kuyizinqubo zokukhiqiza ezisetshenziselwa ukushintsha izakhiwo ezibonakalayo zensimbi nezinye izinto. Ukwelashwa kokushisa kuhlanganisa ukushisa insimbi ezingeni lokushisa eliphezulu kakhulu bese uyiqinisa (ukupholisa ngokushesha). Lokhu kwandisa ubulukhuni bensimbi, kodwa ngesikhathi esifanayo kwenza kube brittle kakhudlwana.
ukuthukuthela
	Ukushisa kwenziwa ngemva kokwelashwa kokushisa futhi kuhilela ukushisa insimbi, kodwa ekushiseni okuphansi kunokwelashwa kokushisa, okulandelwa ukupholisa kancane. Ukuqina kunciphisa ubulukhuni kanye nokuqina kwensimbi, okwandisa ukuqina kwayo. Ngokulawula izinga lokushisa insimbi eshiselwa kulo ngesikhathi sokushisa, ibhalansi yokugcina phakathi kokuqina nokuqina kwensimbi ingashintshwa.
	Kungani ukwelashwa nokushisa kubalulekile konjiniyela bezakhiwo? Amathiphu omaka bonjiniyela aphathwa ngokushisa ukuze aqine. Lokhu kuqina kuyadingeka ukwenza ithiphu libe lukhuni kune-workpiece esetshenziswa kuyo, okuvumela ithiphu ukuthi idwebe umugqa. Ababhali baqina kancane ukuze basuse okunye ukonakala okunikezwa ngesikhathi senqubo yokushisa ukuvimbela ukuphuka ngesikhathi sokusetshenziswa.
i-nickel plating
	I-nickel plating yilapho impahla (imvamisa eyinsimbi) imbozwa ngongqimba lwenikeli. Lokhu kungenziwa ngezizathu eziningana ezifana nokuvikela ukugqwala, ukumelana nokugqoka nokubukeka.
	i-electroplating Ukufakwa kwe-nickel kuvame ukwenza inqubo ebizwa ngokuthi i-electroplating, ngezinye izikhathi ebizwa ngokuthi i-electroplating. Lokhu kwenziwa ngokubeka i-workpiece kwisisombululo se-electrolyte lapho bese kuthiwa i-cathode kanye nenduku ye-nickel ebizwa ngokuthi i-anode.
	I-current eqondile isetshenziswa ku-anode ne-cathode, ngenxa yalokho i-anode ikhokhiswa kahle, futhi i-cathode ikhokhiswa kabi. Ama-nickel ions ku-electrolyte akhangwa ku-cathode futhi afakwe endaweni yokusebenza. Lawa ma-ion ku-electrolyte athathelwa indawo yi-nickel anode ions, ngenxa yalokho i-anode ye-nickel incibilika ku-electrolyte.
	I-electronic coating Ukufakwa kwamakhemikhali akudingi ukusetshenziswa kwamandla kagesi. Esikhundleni salokho, i-preform ifakwe kwisisombululo samanzi esiqukethe i-nickel ions, futhi i-ejenti yokunciphisa (imvamisa i-sodium hypophosphite) yengezwe kwisixazululo.
	Indawo yokusebenza isebenza njenge-catalyst yokusabela, okwenza ama-nickel ion abe isisombululo ukuthi afake kucezu lokusebenza. Isixazululo esinamanzi esiqukethe ama-nickel ion singashiswa sibe ngu-90°C ukusheshisa ukusabela.
	Yiziphi izinzuzo nezingozi zenqubo ngayinye yokumboza? I-Chemical Plating ikhiqiza ungqimba oluningi lwe-nickel olulinganayo futhi olufana kakhulu kunokucwenga, ikakhulukazi ezindaweni ezincibilikisiwe, izimbobo, namaphethelo womsebenzi. Ukugqoka kwamakhemikhali akudingi ukuthi i-workpiece inikwe amandla, ngakho-ke izingxenye eziningi ezincane zingagqunywa kalula ngesikhathi esifanayo kwisisombululo esinamanzi. Kodwa-ke, i-electroplating ngokuvamile iyindlela eshibhile yokugqoka impahla.
I-Anodizing
	I-anodizing yilapho insimbi (imvamisa i-aluminium noma i-magnesium) imbozwe ngesendlalelo se-oxide esizinzile phakathi nenqubo ye-electrolysis. I-anodizing ingasetshenziselwa ukuvikela ukugqwala kodwa isetshenziswa kakhulu ngezinjongo zokuhlobisa.
	I-anodizing yenziwa kanjani? I-anodizing yenziwa ngenqubo ebizwa ngokuthi i-electrolysis. Lokhu kuhlanganisa ukubeka ucezu lokusebenza ku-electrolyte ene-asidi lapho iba i-anode lapho ixhunywe kutheminali ephozithivu yomthombo we-DC. I-cathode yensimbi ifakwa ku-electrolyte ene-asidi futhi ixhunywe kutheminali engalungile yomthombo we-DC.
	Ukugeleza kwamanje kubangela ukuvela kwegesi ye-hydrogen ku-cathode eshajiwe kabi nomoya-mpilo ku-anode preform eshajwe kahle, ebese yenza ungqimba lwe-alumina ku-preform. Kodwa-ke, ungqimba lwe-alumina lugcwele izimbotshana ezincane ezingase zikhuthaze ukugqwala. Lezi zimbotshana zibe sezigcwaliswa ngodayi abanemibala nama-corrosion inhibitors, okunikeza izingxenye ezifakwe i-anodized imibala ehlukahlukene.
Iyiphi impahla engcono?
	Omaka bomzimba be-PVC abagqwali, kodwa amathiphu alezi zimpawu ngokuvamile awanakushintshwa, ngakho awafaneleki kulabo abahlose ukusebenzisa ithuluzi lokumaka njalo. Ababhali bomzimba wensimbi bangagqwala uma bengafakwanga i-nickel plated, okungadala izinkinga nge-cartridges ebenza bajame, ngakho-ke ukushintsha amathiphu kungaba nzima kakhulu. Ababhali be-Aluminium abanako ukonakala kwensimbi noma i-PVC, kodwa abanye abantu bakuthola kulula futhi bakhetha ababhali abasinda kakhulu. Lokhu, vele, ukukhetha komuntu siqu.
