Indawo osebenzisa kuyo amakhoyili ensimbi ingashintsha indlela asebenza ngayo. Usawoti osemoyeni eduze nolwandle uphula i-zinc ngokushesha. Ukungcola okuvela ezimbonini kwenza imvula ene-asidi iqede i-zinc. Ukugcina amakhoyili ezindaweni ezimanzi kungabamba amanzi kubangele nokugqwala okumhlophe. Ukushisa okuphezulu okuvela ekushiseleni noma ekusikeni kungashisa i-zinc futhi kushiye insimbi ivulekele ukugqwala.

Izinkinga Ezivamile
Amakhoyili ensimbi angaba nezinkinga lapho esetshenziswa noma egcinwe:
Ukugqwala okumhlophe kungabonakala uma amanzi ehlala kukhoyili, ikakhulukazi uma ukudlulisa kungenziwanga kahle.
Ukuklwebheka, ukusikeka, noma ukushisela kungalimaza ungqimba lwezinc futhi kwenze ukugqwala kube nokwenzeka kakhulu.
Uma i-zinc ingekho ngisho noma insimbi inokungcola, izindawo ezibuthakathaka zingakheka.
Amabala amnyama angenzeka uma ukugqwala okumhlophe kuqhubeka nokukhula.
Ukugcina amakhoyili ngendlela engalungile, njengasezindaweni ezimanzi, kwenza ukugqwala kube lula.
Qaphela: Bamba amakhoyili ngokucophelela, wahlole njalo, futhi uwagcine ngendlela efanele ukuze umise izinkinga eziningi.
Ikhoyili yensimbi igcina insimbi iphephile ekugqwaleni. Iphinde imise umonakalo. Le nto inamandla futhi ihlala isikhathi eside. Kuyasiza futhi ukonga imali. Abakhi bayisebenzisela uphahla nezindonga. Abakhiqizi bayisebenzisela izimoto nezinto zikagesi. Abathengi badinga ukubheka ubukhulu kanye nesisindo sokugqoka. Kufanele bahlole nebanga. Izindinganiso ze-ASTM zisiza ukuqinisekisa ukuthi ikhoyili ilungile. Umswakamo nosawoti osemoyeni kungashintsha indlela okusebenza ngayo. Ukukhetha ikhoyili efanele kunikeza imiphumela engcono.
FAQ
Iyini injongo eyinhloko yekhoyili yensimbi?
Ikhoyili yensimbi igcina insimbi ingagqwali noma yonakale. I-zinc layer isebenza njengesihlangu. Abakhi nezimboni bayisebenzisela ukwenza izingxenye ezihlala isikhathi eside futhi zihlale ziqinile.
Ukugcotshwa kwe-zinc kukuvimbela kanjani ukugqwala?
I-Zinc ihlangana namanzi nomoya ngaphambi kokuba insimbi ihlangane. Lokhu kwenza isendlalelo esikhethekile phezulu. Ungqimba luvimba amanzi nomoya ukuthinta insimbi.
Abantu basebenzisa kuphi ikhoyili yensimbi kaningi?
Abantu basebenzisa ikhoyili yensimbi ekwakheni, ekwenzeni izimoto, nasekwenzeni izinto zikagesi. Ilungele uphahla, izingxenye zemoto, nezingcezu zemishini.
Ingabe ikhoyili yensimbi ingapendwa?
Ungapenda ikhoyili yensimbi. Indawo engaphezulu idinga ukuhlanzeka futhi yome kuqala. Ama-primers akhethekile asiza ukunamathela kwepende kungqimba lwezinc.
Yiziphi izindinganiso ezisebenza kukhoyili yensimbi?
I-ASTM A653 kanye ne-ISO 3575 yimithetho esemqoka yamakhoyili ensimbi. Le mithetho ikhuluma ngokuthi ukujiya kukhulu kangakanani, ukuthi ubuso bubukeka kanjani, nokuthi bulwa kanjani nokugqwala.
