Njengoba umphakathi uqhubeka uthuthuka, indlela yokukhiqiza yezolimo yendabuko ayisakwazi ukuhlangabezana nezidingo zentuthuko yempucuko yanamuhla, futhi ezolimo ezintsha zifunwa ngabantu abasembonini. Eqinisweni, lokho okubizwa ngokuthi imishini yezolimo ikakhulukazi yizindawo zokugcina izithombo. Akunqunyelwe isikhathi nendawo. Ingenza ukukhiqizwa kwezolimo ezindaweni ezikhethekile njengethafa, izintaba ezijulile kanye nogwadule. Njengomthombo wephrojekthi yokugcina izithombo, izinto kufanele zilawule ikhwalithi yephrojekthi, okokuqala, kusukela ekukhetheni izinto. Isibonelo, ngezingxenye zensimbi ezisetshenziswa kuphrojekthi yokugcina izithombo, insimbi esezingeni eliphezulu izocutshungulwa futhi isuswe. Ngemva kokufaka i-hot plate esitshalweni sobuchwepheshe sokugaya, umnyango wokuhlola ikhwalithi uzoyihlola futhi. Ngemva kokudlula ukuhlolwa, izothuthwa iye endaweni yokwakha ukuze isetshenziswe.

1. Isakhiwo sepayipi lensimbi egayiwe eshisayo: ipayipi eligayiwe elishisayo lenza insimbi encibilikisiwe isabela ne-iron matrix ukukhiqiza ungqimba lwe-alloy, ukuze kuhlanganiswe i-matrix kanye ne-coating. Ipayipi eligayiwe elishisayo elihlinzekwa yi-Tianjin Feilong Pipe Co., Ltd. liqala lifakwe ku-pickle. Ukuze kususwe i-iron oxide ebusweni bepayipi lensimbi, ngemva kokuyigaya, ihlanzwa ngesisombululo samanzi se-ammonium chloride noma i-zinc chloride noma ithangi le-ammonium chloride kanye ne-zinc chloride exubile, bese ithunyelwa ethangini eligayiwe elishisayo. I-hot dip galvanizing inezinzuzo zokugqoka okufanayo, ukunamathela okuqinile kanye nokuphila isikhathi eside kwenkonzo. I-matrix yepayipi lensimbi egayiwe eshisayo inezimpendulo eziyinkimbinkimbi zomzimba nezamakhemikhali ngesisombululo se-melted plating ukuze kwakhiwe ungqimba lwe-zinc ferroalloy olumelana nokugqwala olunesakhiwo esiqinile. Ungqimba lwe-alloy luhlanganiswe nengqimba ye-zinc emsulwa kanye ne-matrix yepayipi lensimbi. Ngakho-ke, inokumelana okuqinile kokugqwala.

2. Isakhiwo sepayipi le-galvanized strip: ipayipi le-galvanized strip lilungisa inqubo yokukhiqizwa kwepayipi le-galvanized elifakwa ngokushisa. Okokuqala, insimbi ye-strip esetshenziselwa ukwenza amapayipi kufanele ihlungwe ukuze kususwe i-iron oxide ebusweni bensimbi ye-strip. Bese yomiswa ngomoya bese kwenziwa ipayipi. Isembozo sifana futhi sikhanya, kanti inani le-zinc plating lincane, elingaphansi kwezindleko zokukhiqiza ipayipi le-galvanized elifakwa ngokushisa. Ukumelana kwayo nokugqwala kubi kancane kunokwepayipi le-galvanized elifakwa ngokushisa.
