Ukugqwala Kwepayipi Lensimbi Elivunyiwe

Ipayipi lensimbi eliphehliwe ukugqwala kungokwe-zinc encibilika ku-asidi futhi kuphinde kuncibilike ku-alkali, ngakho kubize ngensimbi yobulili.I-Zinc emoyeni owomile cishe ayishintshi.Emoyeni onomswakama, indawo engaphezulu ye-zinc izokhiqiza ifilimu eliminyene le-zinc carbonate eyisisekelo.Iqukethe i-sulfur dioxide, i-hydrogen sulfide kanye nomkhathi wasolwandle, ukungaphatheki kahle kokugqwala kwe-zinc, ikakhulukazi emkhathini oshisayo noswakeme oqukethe ama-organic acid, i-zinc enamathela kalula ingaba nokugqwala.I-Zinc standard electrode potential of-0.76V, i-substrate yensimbi, i-zinc enamathela i-anodic coating, esetshenziselwa ukuvimbela ukugqwala kwensimbi nensimbi, ubuhle nobubi bezakhiwo zayo zokuzivikela zobudlelwane bokujiya kwe-coating mkhulu.

I-Zinc enamathela, i-passivation, staining noma i-coating egcina i-ejenti yokukhanya, ingathuthukisa kakhulu ukuzivikela nokuhlobisa.I-Zinc oxide emoyeni, ubuso bokwakheka kokugqwala okumhlophe, lesi simo sivamile.Kuncike strip yakho kuyinto idiphu hot lashukumisa noma electro-lashukumisa, dip hot lashukumisa, ke ngenxa ungqimba kuqhathaniswa obukhulu zinc ukukhiqiza ukugqwala okumhlophe akuphazamisi iwaranti evamile, ngoba izinga oxidation of zinc emoyeni kancane kakhulu.Electro-galvanized akulula ukusho.Ungaboni ukugqwala ngeke kuthinteke.Lapho ufuna ukusindisa insimbi lashukumisa ukuba uqaphele ungabeki komoya omanzi futhi hot sezulu kulula kakhulu ukubumba, abanye ebusika, bese unamathela eside.

Izidingo zobuchwepheshe zepayipi Lensimbi Eyisithako

Ukuze uthole inqubo yokuhlola ikhwalithi yamapayipi ensimbi ediphozi ashisayo, iphuzu eliyinhloko ukusebenza kwepayipi lensimbi elinamandla.
Iphuzu lokugoba lediphu elishisayo eliphehliwe libhekisela entweni yensimbi enesivuno, izinga lokugoba lesampula ensimbini eyakhiwe ekuqaleni ibaluleke kakhulu, ngoba ingahlola ipayipi lensimbi elinamandla ngokucindezela kwangaphandle lapho ukusabela. , uma test lashukumisa steel ipayipi ingcindezi iphuzu esibucayi, singaba efanele ukuqinisa lashukumisa ipayipi lensimbi ukuze ukuthengeka okukhulu ngokuvumelana nezidingo zamakhasimende.
Uma amandla ehla, kufanele ahlukanise phakathi kwephuzu lokukhiqiza eliphezulu neliphansi.Iphuzu eliphezulu lesivuno liyisampula lokukhipha amandla okokuqala ngqa ngaphambi kokuba kwenzeke ukucindezeleka okukhulu;Iphuzu lesivuno esiphansi liwukucindezeleka okuncane lapho ungafaki umphumela wesikhashana wokuqala, isigaba sesivuno.Inkomba yezinto zensimbi yobulukhuni ukumelana nezinto eziqinile ihlobisa ikhono lendawo, eyaziwa ngokuthi ubulukhuni.
Ngokuya ngezindlela zokuhlola kanye nobubanzi bobulukhuni bungahlukaniswa ngokuqina kwe-Brinell, ukuqina kwe-Rockwell, ukuqina kwe-Vickers, ukuqina koShore, ubulukhuni obuncane kanye nobulukhuni bezinga lokushisa eliphezulu.Okuvame ukusetshenziselwa ipayipi Brinell, Rockwell, Vickers ubulukhuni.
