Okwamanje,16Mn ipayipi lesikwele elingenamthungoubuchwepheshe bukhule ngokwedlulele, futhi kukhona amazinga omkhiqizo ahambisanayo kanye nezinhlobo ezahlukene zobuchwepheshe bokusebenza. 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.
