ukuhlukaniswa
Ishubhu yesikwele ekhandwe ngensimbi ihlukaniswe yaba ishubhu lesikwele elishisiwe kanye neshubhu lesikwele elibandayo elibandayo elivela kunqubo yokukhiqiza.Kungenxa yokuthi ukucutshungulwa kwala mashubhu ayisikwele amabili anezinsimbi kuhlukile ukuthi anezakhiwo eziningi ezihlukene zomzimba namakhemikhali.Ngokuvamile, zihlukile ngamandla, ukuqina kanye nezakhiwo zemishini.
Ishubhu eliyisikwele elishisayo lediphu eliyisikwele: liyishubhu eliyisikwele elishiselwa ngemva kokuba ipuleti lensimbi noma umucu wensimbi ugoqwe futhi wakheke, futhi lakheka ngemva kochungechunge lokusabela kwamakhemikhali echibini elishisayo lediphu elinothayela ngesisekelo saleli shubhu lesikwele.Inqubo yokukhiqiza ye-hot-dip galvanized square tube ilula, futhi ukusebenza kahle kokukhiqiza kuphezulu kakhulu, futhi kunezinhlobonhlobo eziningi kanye nokucaciswa.Le tube yesikwele idinga imishini embalwa kanye nezimali, ezifanele ukukhiqizwa kwabakhiqizi be-tube square galvanized square.Kodwa ngokwamandla, amandla alolu hlobo lwepayipi lensimbi aphansi kakhulu kunalawo epayipi eliyisikwele elingenamthungo.
Ipayipi elibandayo le-galvanized square
Futhi ishubhu yesikwele esibandayo esiwuthayela ukusebenzisa umgomo wokubanda okubandayo eshubhuni lesikwele elisetshenziselwa ukwenza ishubhu lesikwele libe nokusebenza kokuqeda ukugqwala.Ihluke ekushiseni okushisayo, i-galvanizing coating ebandayo ikakhulukazi isebenzisa isimiso se-electrochemical ukuvimbela ukugqwala, ngakho-ke kuyadingeka ukuqinisekisa ukuthintana okugcwele phakathi kwe-zinc powder nensimbi ukukhiqiza umehluko ongaba khona we-electrode, ngakho-ke ukwelashwa kwendawo yensimbi kubaluleke kakhulu.
Umehluko phakathi kwe-galvanizing eshisayo nebandayo
Amashubhu ayisikwele aphekiwe afaka phakathi ishubhu yesikwele eshisiwe ne-electrogalvanized square tube.Ishubhu yesikwele esishisayo sediphu ihlanganisa indlela emanzi, indlela eyomile, indlela ye-zinc eholayo, indlela yokunciphisa i-oxidation, njll. Umehluko omkhulu phakathi kwezindlela ezihlukene zediphu ezishisayo ukuthi iyiphi indlela esetshenziswayo ukuze kusebenze ubuso bomzimba wepayipi ukuze kuthuthukiswe ikhwalithi. yokugcoba emva kokuhlanza i-asidi yepayipi yensimbi.Njengamanje, indlela eyomile kanye nendlela ye-redox isetshenziswa kakhulu ekukhiqizeni, futhi izici zabo ziboniswa etafuleni.Ubuso be-zinc layer bushelelezi kakhulu, buminyene futhi bufana;Izakhiwo ezinhle zemishini nokumelana nokugqwala;Ukusetshenziswa kwe-zinc kuphansi ngo-60% ~ 75% kunaleyo yokufaka ama-galvanizing ashisayo.I-Electrogalvanizing inobunzima obuthile bobuchwepheshe, kodwa kufanele isetshenziselwe ukunamathela ohlangothini olulodwa, ukunamathela okunezinhlangothi ezimbili ezinogqinsi oluhlukene lokumboza endaweni yangaphakathi nengaphandle, kanye nokufaka uthayela kweshubhu eludongeni elincanyana.
