Ishidi lensimbi elakhiwe ngensimbikuwuhlobo lwempahla yokwakha abantu abaningi abazokhetha ukuyithenga. Lapho ukhetha ishidi lensimbi elinama-galvanized, abantu bazonaka izici nezici zalo. Ngakho-ke yiziphi izici zeshidi lensimbi elinamandla? Yiziphi izici ze-galvanized steel plate?
1, Yiziphi izici zensimbi yamapulangwe
1. Amapuleti ensimbi ane-galvanized anokwethenjelwa okuhle, futhi ungqimba lwama-galvanized luhlanganiswe nensimbi, lube yingxenye yendawo yensimbi. Ngakho-ke, ukuqina kwe-coating kuqhathaniswa nokwethenjelwa.
2. Ipuleti lensimbi eliphehliwe linokumelana nokugqwala. Amapuleti ensimbi enziwe ngensimbi ambozwe ngongqimba lwezinc eyinsimbi ukuvimbela ukugqwala endaweni futhi andise impilo yayo yesevisi. Lolu hlobo lwepuleti yensimbi eboshwe lubizwa ngokuthi i-galvanized steel plate. I-galvanizing iyindlela eyongayo nephumelelayo yokuvimbela ukugqwala evame ukusetshenziswa, futhi cishe ingxenye yokukhiqizwa kwe-zinc emhlabeni isetshenziswa kule nqubo. Ipuleti lensimbi eliphehliwe wuhlobo olubalulekile lweipuleti lensimbi lokulwa nokugqwala, hhayi kuphela ngenxa yokuthi i-zinc ingakha ungqimba oluqinile oluvikelayo ebusweni bensimbi, kodwa futhi ngoba i-zinc inomphumela wokuvikela we-cathodic. Uma ungqimba olunothayela lonakalisiwe, lusengakwazi ukuvimbela ukugqwala kwezinto eziyisisekelo ezisekelwe kunsimbi ngokuvikelwa kwe-cathodic.
3. Ukumbozwa kwepuleti lensimbi enamapulangwe kunokuqina okuqinile, okwenza isakhiwo esikhethekile se-metallurgical esingamelana nokulimala komshini ngesikhathi sokuthutha nokusetshenziswa.
I-2, Yiziphi izici zepuleti lensimbi elinamandla
1. Ipuleti lensimbi elakhiwe kahle linokumelana ne-oxidation. Ukumelana ne-oxidation engaphezulu kwepuleti lensimbi elinamandla kunamandla, okungathuthukisa ukumelana nokugqwala kanye nekhono lokungena lezingxenye.
2. Ipuleti lensimbi elakhiwe ngensimbi linenzuzo yokuvikela ngokuphelele, futhi yonke ingxenye yengxenye epuletiwe ingagcotshwa nge-zinc, inikeze ukuvikeleka okuphelele ngisho nasezindaweni eziphansi, emakhoneni abukhali, nasezindaweni ezifihliwe.
Ishidi lensimbi eliphehliwe liqinile futhi lihlala isikhathi eside, futhi ezindaweni zasemadolobheni, ungqimba olujwayelekile lokuvikela ukugqwala okungama-galvanized lungagcinwa iminyaka engaphezu kwengu-50 ngaphandle kwesidingo sokulungiswa. Ezindaweni zasemadolobheni noma ezingasogwini, ungqimba olujwayelekile lokuvimbela ukugqwala okungaba yizinsimbi lungagcinwa iminyaka engama-20 ngaphandle kwesidingo sokulungiswa.
