Okwamanje,16Mn ipayipi lesikwele elingenamthungoubuchwepheshe bukhule ngokwedlulele, futhi kukhona amazinga omkhiqizo ahambisanayo kanye nezinhlobo ezahlukene zobuchwepheshe bokusebenzisa.Izinkambu zayo zokusebenza nazo zibanzi kakhulu.Ngenxa yethonya lesimo sezulu nemvelo, ingaphezulu lepayipi lesikwele elingenamthungo elingu-16Mn lizogqwala ngemva kokusetshenziswa okuqhubekayo.Ungazisusa kanjani izindawo zokugqwala zamashubhu ayisikwele angenamthungo angu-16Mn?Ngizokhuluma ngayo ngikuhlaziyele yona.
1.Ukuze kuzuzwe umphumela omuhle wokuqeda i-16Mn ngaphandle komthungoipayipi lesikwele, kuyadingeka ukunquma i-abrasive ngokusho kokuqina, i-corrosion degree yasekuqaleni, ubulukhuni obudingekayo kanye nohlobo lokumboza lwepayipi ye-alloy, njenge-epoxy yongqimba olulodwa, ungqimba olubili noma ungqimba lwe-3-layer polyethylene.Ukuze kuzuzwe umphumela omuhle wokuqeda amandla, kuyadingeka ukusebenzisa i-abrasive exubile yesihlabathi sensimbi nesibhamu sensimbi.Njengoba isibhamu sensimbi singaqinisa ingaphezulu lensimbi, isihlabathi sensimbi singagqwalisa indawo yensimbi.
2.Ibanga le-Derusting: uma kuqhathaniswa nenqubo yokwakha ye-epoxy, i-ethylene, i-phenolic nezinye izigqoko ezilwa nokugqwala ezivame ukusetshenziselwa i-16Mn engenamthungo.amapayipi ayisikwele, imfuneko eyisisekelo iwukwenza ubuso bamapayipi e-alloy bufinyelele eduze nezinga elimhlophe.Ukuzijwayeza kufakazele ukuthi ibanga lokukhipha ukugqwala lingasusa cishe sonke isikali se-oxide, futhi ukungcola okunjengokugqwala kungahlangabezana ngokugcwele nezimfuneko zokunamathisela ze-anti-corrosion coating kanye ne-alloy pipe.Ubuchwepheshe bokukhipha ukugqwala kokufutha bungenza ngokuzinza nangokuthembekile ikhwalithi ifinyelele ezingeni elimhlophe eliseduze, futhi izindleko ziphansi.
3.Ngaphambi kokufafaza ukwelashwa, isikali samafutha ne-oxide sisusiwe ebusweni bepayipi lesikwele elingenamthungo elingu-16Mn.Idinga futhi ukushisisa ku-40-60 ℃ ngesithando somlilo ukuze igcine ingaphezulu lepayipi lengxube yomile.Njengoba indawo yepayipi ye-alloy ayinawo amafutha nokunye ukungcola, umphumela wokukhipha ukugqwala ungathuthukiswa.Ngaphezu kwalokho, indawo eyomile yepayipi ye-alloy nayo inenzuzo ekuhlukaniseni isibhamu sensimbi, isihlabathi sensimbi, ukugqwala kanye nesilinganiso se-oxide, okuzokwenza ipayipi ye-alloy ngemva kokususwa kokugqwala.
4.Ukuze kutholwe ukuhlanzeka okungcono okufanayo kanye nokusatshalaliswa kokuqina kwepayipi eliyisikwele elingenamthungo elingu-16Mn, ucwaningo nokusungulwa kosayizi nengxenye yezinhlayiyana eziqhuma kubaluleke kakhulu.Ngenxa yokuthi ubugwebu bukhulu kakhulu, i-anti-corrosion coating kulula ukuba izacile esiqongweni sentambo okusetshenzwa kulengwa kuyo, futhi ngenxa yokuthi intambo okusetshenzwa kulengwa kuyo ijule kakhulu, amabhamuza akheka kalula enqubweni yokulwa nokugqwala, okuthinta kakhulu ukusebenza. we-anti-corrosion coating.
Umongo wokwelapha okuqinisa ukuguga uwukuthela izinhlayiya eziningi ezinhle kakhulu ezinezimvula ezivela kusisombululo esiqinile esine-supersaturated ukuze zakhe indawo efanayo yokucebisa i-athomu encane encibilikayo.Ukuze uqinisekise ukuthi i-solute ayincibiliki kakhulu esixazululweni esiqinile lapho kushiswa ishubhu lesikwele esingu-16Mn esingenamthungo, bese kuba nesilinganiso sokuncibilika ekupholiseni okusheshayo, ukuze i-solute eyeqile eyethulwe sekwephuze kakhulu izokwakha isisombululo esiqinile esine-supersaturated, ukucisha kudinga kwenziwe ngaphambi kokwelashwa kokuguga.Enqubweni yokwelashwa kokushisa kwe-16Mn yesikwele seshubhu engenamthungo, izinga lokushisa lokushisa kufanele lilawulwe ngokuqinile ngesikhathi sokwelashwa kokuguga ukuze kwenziwe i-solute inyibilike ibe yisixazululo esiqinile ngangokunokwenzeka ngaphandle kokuncibilika ingxubevange.
