Kwimveliso yemizi-mveliso. IiCasters, njengenxalenye ebalulekileyo yobuchwepheshe bayo bonyango lomphezulu, kubalulekile ukuphucula ubuhle, ukuqina kunye nokumelana nokugqwala kwemveliso. IGalvanizing njengonyango oluqhelekileyo lomphezulu. Isetyenziswa kakhulu kunyango lomphezulu lwee-alloys ze-caster. Eli nqaku liza kuchaza iindlela ezahlukeneyo eziqhelekileyo zokugaya ii-casters, eziquka i-cyanide galvanizing, i-zincate galvanizing, i-chloride galvanizing, kunye ne-sulfate galvanizing. Yenzelwe ukunika abafundi isalathiso esibanzi sobugcisa.
1, i-Cyanide galvanization
I-Cyanide galvanizing, ngenxa yamandla ayo aphezulu okusasazeka kunye nomgangatho olungileyo wokugquma. Ngaxa lithile yayikwindawo ebalulekileyo kushishino lwe-electroplating. Nangona kunjalo. Ngenxa yendalo enobuthi kakhulu ye-cyanide ngokwayo kunye nosongelo olunokubakho kwindalo esingqongileyo. Ukusetyenziswa kwayo kuthintelwe kakhulu. Nangona kunjalo, uphuhliso lweenkqubo ze-low-cyanide (microcyanide) galvanizing. Ukwenza kube nokwenzeka ukuqinisekisa umgangatho wemveliso ngelixa kunciphisa iingozi kwindalo esingqongileyo. Phantsi kwenkqubo ye-cyanide galvanizing, umgangatho wemveliso ulungile emva kokugquma inxalenye yehardware ye-caster. Ingakumbi emva kokuba i-color plating ingasebenzi, imibala ihlala ikhanya ixesha elide.
2, amagama anxulumene ne-zincate galvanized caster welding kunye neengcamango
Inkqubo ye-zincate galvanizing yindlela enobuhlobo nokusingqongileyo endaweni ye-cyanide galvanizing. Okwangoku, zahlulwe ngokubanzi zibe luchungechunge lwe-"DPE" lwe-Wuhan Institute of Materials Protection kunye nochungechunge lwe-"DE" lwe-Guangdian Institute. Zombini zenziwe nge-zincate galvaning kunye nezongezo ze-alkaline. Ineempawu zesakhiwo se-columnar lattice sokugquma, ukumelana nokugqwala okuhle, kwaye ifanelekile kwi-color galvanizing. Indlela yayo eqhelekileyo ibandakanya i-NaOH, i-ZnO, kunye nezongezo ezithile. Umzekelo, indibaniselwano ye-"DPE-II" kunye ne-ethanolamine. Le nkqubo ifuna ulawulo oluqinileyo lokwakheka kwesisombululo sokugquma kunye neemeko zenkqubo, ezifana ne-pH, ubushushu, kunye noxinano lwangoku, ukuqinisekisa umgangatho wokugquma. Emva kokuba imveliso iphumile etankini, kufuneka idlule kuthotho lwamanyathelo okucubungula emva kokucubungula, njengokuhlamba, ukupolisha, ukuthambisa kunye nokomisa, ukuze kufunyanwe iziphumo ezilungileyo.
3, i-chloride galvanization
Inkqubo yokugaya i-chloride isetyenziswa kakhulu kushishino lwe-caster hardware plating. Ipesenti ingaphezulu kwe-40%. Inkangeleko yenkqubo engasebenziyo (eluhlaza okwesibhakabhaka okanye emhlophe okanye esilivere) iyafana neye-chrome plating. Kwaye ixabiso liphantsi. Iifomyula eziqhelekileyo zokugaya i-chloride ziquka i-KCl, i-ZnCl_2, i-H_3BO_3 (i-buffer), kunye nee-brighteners ezithile. Le nkqubo ifanelekile ngokukodwa kwi-white passivation (eluhlaza okwesibhakabhaka, emhlophe, emhlophe). Phakathi kwazo, i-silver-white passivation ngenxa yombala wayo ozinzileyo. Ihlala ikhethwa njengokhetho lokuqala. Nangona kunjalo, kubalulekile ukuqaphela ukuba i-Chloride galvanized coatings, xa ivezwe emoyeni ixesha elide, i-membrane ithambekele ekutshintsheni umbala. Ichaphazela imbonakalo kunye nokumelana nokugqwala kwemveliso. Ke ngoko, kuyimfuneko ukuthatha amanyathelo afanelekileyo ukuthintela ukujika kombala.
4, i-sulfate galvanization
Inkqubo ye-sulfate galvanizing, enexabiso layo eliphantsi kunye nokufaneleka kwayo kwi-plating eqhubekayo (umz., ucingo, umcu, njl.njl.). Indawo kwishishini le-electroplating. Iifomyula eziqhelekileyo zale nkqubo ziquka i-ZnSO_4, i-H_3BO_3, kunye nee-brighteners ezithile. Ixabiso le-pH ye-sulfate galvanizing ngokubanzi lilawulwa phakathi kwe-4.5 kunye ne-5.5. Ngokulungisa ukwakheka kwesisombululo se-plating kunye neemeko zenkqubo, i-A coating enokumelana nokugqwala okuhle kunye nokukhanya inokufumaneka. Nangona kunjalo. Xa kuthelekiswa nezinye iinkqubo ze-galvanizing, i-Sulfate galvanizing inokuba ngaphantsi kancinci ngokwe-gloss kunye nokufana kwe-coating.
amagqabaza okuqukumbela
Ngamafutshane. Ii-casters zenziwe nge-galvanised ngeendlela ezahlukeneyo. Indlela nganye ineenzuzo zayo ezizodwa kunye nobubanzi bokusetyenziswa. Ngokwesiqhelo. Kufuneka isekelwe kwindawo ethile yokusetyenziswa kunye neemfuno zokusebenza kwe-caster. Khetha inkqubo efanelekileyo ye-galvanised. Okwangoku. Ngemithetho yokusingqongileyo engqongqo ngakumbi kunye nokuqhubela phambili kwitekhnoloji ye-plating, inkqubo ye-galvanised enobuhlobo nokusingqongileyo, esebenza kakuhle kwaye engabizi kakhulu iya kuba yindlela yophuhliso lwexesha elizayo.
