Insimbi engaphekiwe isetshenziswa kakhulu ekwakheni, ekukhiqizeni, kwezolimo nasekusetshenzisweni kwansuku zonke ngenxa yokumelana nokugqwala okuqinile. Abathengi abaningi bakhetha insimbi enamapulangwe kumaphrojekthi angaphandle, ukufulela, ama-guardrails, izinhlelo ze-HVAC, nezakhiwo zensimbi. Kodwa umbuzo owodwa ovamile uvela njalo: Ingabe insimbi engagqwala ingagqwala?
Nakuba insimbi eyisithako iklanyelwe ukumelana nokugqwala, ayivikelekile ngokuphelele ekugqwaleni ngaphansi kwezimo ezithile. Ukuqonda ukuthi insimbi ethathiwe izivikela kanjani—kanye nezimo ezingase zibangele ukugqwala—kukusiza ukuthi wenze izinqumo ezingcono zokuthenga futhi wandise isikhathi sokuphila samaphrojekthi akho. Lesi sihloko sihlinzeka ngencazelo ecacile yokuthi kungani insimbi engagqwala ingagqwala, ukuthi ihlala isikhathi esingakanani ingenayo ukugqwala, izici ezivamile ezibangela ukugqwala, kanye nemikhuba yokuvikela engcono kakhulu. Iphinde ihlanganise amacala okusetshenziswa komhlaba wangempela namathiphu okulungisa asebenzayo, okwenza lo mhlahlandlela ulungele onjiniyela, osonkontileka, nabasebenzisi bokugcina.
Iyini Insimbi Yensimbi?
Insimbi eyi-galvanized empeleni iyi-carbon steel ehlanganiswe nongqimba lwe-zinc. I-zinc coating isebenza njengesithiyo esivikelayo sokuvimbela umswakama, amakhemikhali, nomoya-mpilo ukuthi ungathinteki ngokuqondile endaweni yensimbi. Lokhu kunamathela kubambezela ukufakwa kwe-oxidation futhi kwandisa kakhulu impilo yesevisi yensimbi.
Izinhlobo ezivame kakhulu zihlanganisa:
Phakathi kwazo, insimbi eyakhiwe ngothayela eshisayo inikezela ngokujiya kakhulu kanye nokumelana nokugqwala okungcono kakhulu, okuyenza idume ngamashidi okufulela, ikhoyili yensimbi, imishayo yesakhiwo, uthango, nezinhlelo zokufulela zensimbi.
