Kwidiphu eshushu yeepleyiti zedyokhwe ezisetyenziswa kwiintambo zothumelo lombane, ukuphunyezwa okusemgangathweni kwenkqubo yediphu eshushu-yediphu imisela ngokuthe ngqo ubomi benkonzo yemveliso kunye nokusebenza kokhuseleko. Eli nqaku liza kunika isingeniso esicacileyo kwiinkalo zemigaqo yenkqubo, iinkqubo eziphambili, amanqaku aphambili okulawula umgangatho, iingenelo zenkqubo, kunye nemigangatho yokuthotyelwa kwezorhwebo lwangaphandle.
Kushushu-dip galvanizing ngokubalulekayo kukusabeleko lwentsimbi. Xa umphezulu -idyokhwe yentsimbi ecociweyo intywiliselwa kwi-zinc etyhidiweyo malunga ne-450 degree, i-iron (Fe) kwi-substrate yentsimbi kunye ne-zinc (Zn) kwi-zinc etyhidiweyo ingena kwi-diffusion eqhubekayo kunye ne-alloying reaction, isenza umaleko wesithathu{4}} Ukusuka ngaphakathi nangaphandle, ezi maleko zezi:
I-Iron-I-Zinc Alloy Layer (I-Inner Layer): Idityaniswe ngokuthe ngqo kwi-substrate yentsimbi, ikakhulu eyenziwe yi-Fe3Zn10 kunye ne-FeZn7, ixinene kwaye inoncamathelo eyomeleleyo, inika isiqinisekiso esingundoqo sokuxhathisa umhlwa kunye ne-anti{4}}ipropathi yokukrazula yomaleko we-galvanized.
I-Zinc-I-Iron Alloy Layer (i-Middle Layer): Yenziwe nge-FeZn13, inobungqingqwa obuphakathi kwaye idibanisa ukuqina kunye nokuqina.
I-Zinc ecocekileyo (i-Outer Layer): Ukugubungela umgca ongaphandle, ithambile kwaye i-ductile, yenza ifilimu ekhuselayo ye-zinc oxide ebusweni. Ngaphezu koko, xa kwenzeka imikrwelo yendawo, inika ukhuseleko oluqhubekayo kwindawo ekhutshiweyo ngokusebenzisa umphumo wokukhuselwa kwe-anodic.
KwiiPleti zeYoke ezishushu zeDip, ubukhulu bubonke bezinto ezintathu-isakhiwo somaleko kufuneka silawulwe ngokungqongqo ukuba sibe ngaphezulu kwe-65μm. Kwizicelo eziphezulu-ezifunekayo, ubukhulu bunganyuswa ukuya kwi-85μm ukuhlangabezana neemfuno zesitshizi setyuwa ephezulu kunye nemekobume ezonakalisa kakhulu.
Inkqubo yemveliso yeHot Dip yeePlati zeYoke ezivuthelweyo kufuneka ilandele inkqubo esemgangathweni yonyango lwangaphambili - kushushu{1}}dip galvanizing - posttreatment - yokuhlolwa. Phakathi kwabo, ukunyangwa kwangaphambili kuyinyathelo eliphambili elimisela umgangatho we-galvanizing kwaye lichaphazela ngokuthe ngqo ukunamathela kunye nokufana kwengubo.
Ukunciphisa unyango: Sebenzisa i-alkaline degreasing agent ukuze ufunxe kwi-60-80℃for 5{3}}10 imizuzu, okanye usebenzise{5}uxinzelelo oluphezulu lokucoca ukutshiza ukususa i-oyile yestamping, i-oyile ethintela umhlwa, uthuli kunye namabala e-oyile kumphezulu wepleyiti yokudibanisa. Iimida ezigxininisiweyo zeplate yejoka kunye neendonga zangaphakathi zemingxuma ye-bolt ziindawo ezixhomekeke kwi-oyile ye-oyile, efuna ixesha lokutshiza elongezelelweyo okanye ukucocwa kwe-ultrasonic.
Ukuvasa nokucocwa kwamanzi: Sula ngetanki yokuhlamba amanzi esisiseko kunye neyesibini ukuze ususe i-arhente yokucoca intsalela. Le nkqubo kufuneka iqinisekise ukuba akukho kuqokelelana kwamanzi okanye i-arhente eshiyekileyo kwimingxuma yeebholiti.
Ukucholwa kweasidi kunye nokususa umhlwa: Sebenzisa i-hydrochloric acid ukukha, ukuntywiliselwa kwiqondo lobushushu legumbi kangange-10{2}}imizuzu eyi-15 ukususa isikali seoksidi, irusi, kunye ne-rolling oxide layer ukusuka kwipleyiti yedyokhwe. Kwisikali se-oxide esityebileyo, ixesha lokukhetha linokwandiswa ngokufanelekileyo, kodwa ulawulo olungqongqo luyafuneka ukuze kuthintelwe ukucolwa ngokugqithisileyo, okunokukhokelela kuburhabaxa bomphezulu kunye nokuncipha kokuncamathela kokwambathisa.
Ukuhlanjwa kwamanzi kunye nokungathathi hlangothi: ntywiliselwa kwitanki ye-alkaline yokungathathi hlangothi ukuze unciphise izinto ezishiyekileyo ezineasidi, uqinisekise umgangatho ongathathi hlangothi. Iindonga zangaphakathi zemingxuma yebholithi kufuneka zihlanjululwe ngokucokisekileyo ukuze kuthintelwe intsalela ye-asidi ekubangeleni amadyunguza kumaleko egalvanized.
Drying and preheating: Dry at 120-150℃ for 10-15 minutes to completely remove surface moisture. The surface must be free of water stains and oxidation; otherwise, the galvanized layer may show signs of blistering or exposure to oxidized material. Defects such as those mentioned above; Zinc immersion: The zinc immersion temperature is strictly controlled at 445-460℃. The immersion time is adjusted according to the thickness of the plate. When the thickness is ≤6mm, the immersion time is 1-2 minutes. When the thickness is >6mm, ixesha lokuntywiliselwa yimizuzu emi-2-3. Unyango lokupholisa: Sebenzisa ukupholisa umoya okanye ukupholisa inkungu yamanzi ukupholisa kwiqondo lobushushu begumbi. Ngexesha lenkqubo yokupholisa, kunqanda ukungqubana phakathi kweHot Dip Galvanized Yoke Plates ukuthintela imikrwelo kwi-coating.
KwiiPlati zeYoke ezishushu zeDip ezithunyelwa ngaphandle, inkqubo yokuvelisa kufuneka ihlangabezane nemigangatho efanelekileyo kunye neemfuno zesatifikethi semarike ekujoliswe kuyo; kungenjalo, abayi kuba nako ukungena emarikeni. Njengomvelisi oyingcali, inkampani yethu ibeka phambili umgangatho wemveliso; nceda uzive ukhululekile ukuthenga.
