Ngoku,16Mn umbhobho wesikwere ongenamthungoitekhnoloji ikhule ngokugqithisileyo, kwaye kukho imigangatho yemveliso ehambelanayo kunye neentlobo ezahlukeneyo zetekhnoloji yesicelo. Imimandla yesicelo sayo nayo ibanzi ngokugqithisileyo. Ngenxa yempembelelo yemozulu kunye nokusingqongileyo, umphezulu we-16Mn umbhobho wesikwere ongenamthungo uya kuhlwa emva kokusetyenziswa ngokuqhubekayo. Ungawasusa njani amabala erusa ee-16Mn ezingenamthungo zeetyhubhu zesikwere? Ndiza kuthetha ngayo ndikuhlalutyele yona.
1.Ukuze kuphunyezwe isiphumo esifanelekileyo sokuthotywa kwe-16Mn ngaphandle komthungoumbhobho wesikwere, kuyimfuneko ukumisela i-abrasive ngokobulukhuni, i-degree ye-corrosion yasekuqaleni, uburhabaxa obufunekayo bomgangatho kunye nohlobo lokugquma lombhobho we-alloy, njenge-epoxy yomgca omnye, i-two-layer okanye i-3-layer polyethylene. Ukuze ufezekise umphumo ofanelekileyo wokutshatyalaliswa, kuyimfuneko ukusebenzisa i-abrasive edibeneyo yesanti yensimbi kunye ne-steel shot. Ekubeni i-steel shot inokomeleza umgangatho wensimbi, isanti yensimbi inokugqwala indawo yentsimbi.
2.Ibakala lokulahla: xa kuthelekiswa nenkqubo yokwakhiwa kwe-epoxy, i-ethylene, i-phenolic kunye nezinye iingubo ezichasene nomhlwa eziqhelekileyo ezisetyenziselwa i-16Mn engenamthungo.imibhobho yesikwere, imfuneko esisiseko kukwenza umphezulu wemibhobho ye-alloy ifikelele kufuphi nenqanaba elimhlophe. Ukuziqhelanisa kuye kwabonisa ukuba ibakala lokususa umhlwa linokususa phantse yonke imilinganiselo ye-oxide, kwaye ukungcola okufana nomhlwa kunokuhlangabezana ngokupheleleyo neemfuno zokuqhotyoshelwa kwe-anti-corrosion coating kunye ne-alloy pipe. Iteknoloji yokususa i-rust yokutshiza inokuzinza kwaye ithembekileyo yenza umgangatho ufikelele kwinqanaba elimhlophe elikufutshane, kwaye ixabiso liphantsi.
3.Ngaphambi kokutshiza unyango, igrisi kunye nesikali se-oxide sisusiwe kumphezulu we-16Mn umbhobho wesikwere ongenamthungo. Kwakhona kufuneka ifudunyezwe kwi-40-60 ℃ ngesithando sokufudumala ukugcina ubuso bombhobho we-alloy womile. Ekubeni umphezulu wombhobho we-alloy awunayo igrisi kunye nolunye ukungcola, umphumo wokususwa kwe-rust unokwandiswa. Ukongezelela, umbhobho we-alloy owomileyo uluncedo kwakhona ekuhlukaneni kwentsimbi yensimbi, isanti yensimbi, i-rust kunye ne-oxide scale, eya kwenza umbhobho we-alloy emva kokususwa kwe-rust.
4.Ukuze kufumaneke ukucoceka okufanayo kunye nokusabalalisa uburhabaxa be-16Mn yombhobho wesikwele ongenamthungo, uphando kunye nokuveliswa kwesayizi ye-abrasive particle kunye nomlinganiselo kubaluleke kakhulu. Ngenxa yokuba uburhabaxa bukhulu kakhulu, i-anti-corrosion coating kulula ukuba ibe yincinci kwincopho yomgca we-ankile, kwaye ngenxa yokuba umgca we-ankile unzulu kakhulu, amaqamza akhiwa ngokulula kwinkqubo yokuchasana nomhlwa, echaphazela kakhulu ukusebenza. yokwaleka okuchasene nomhlwa.
Undoqo wonyango lokomelezwa kokwaluphala kukugalela amasuntswana amaninzi acolekileyo asuka kwisisombululo esiqinileyo esine-supersaturated ukwenza indawo efanayo yokutyebisa i-athomu encinci yesolute. Ukuze kuqinisekiswe ukuba i-solute ayinyibiliki kakhulu kwisisombululo esiluqilima xa kufudunyezwa i-16Mn ityhubhu yesikwere esingenamthungo, kwaye ke umlinganiselo wokunyibilika kwi-solute ekhawulezayo yokupholisa, ukuze i-solute egqithisileyo yaziswa kade kakhulu iya kwenza isisombululo esiluqilima, ukucinywa kufuneka lwenziwe phambi konyango lokuguga. Kwinkqubo yonyango lobushushu lwe-16Mn ityhubhu yesikwere esingenamthungo, ubushushu bokufudumala kufuneka bulawuleke ngokungqongqo ngexesha lonyango lokuguga ukwenza i-solute inyibilike kwisisombululo esiqinileyo kangangoko kunokwenzeka ngaphandle kokunyibilikisa i-alloy.
