Zomangira zapamwamba za nitrided ndi mbiya
Nitriding Njira: Nitriding ndi mankhwala owumitsa pamwamba pomwe nayitrogeni amagawanika pamwamba pa zinthu kuti apange wosanjikiza wolimba wa nitride.Njira imeneyi nthawi zambiri imaphatikizapo kutenthetsa mbiya ya screw mu mpweya wolamulidwa ndi ammonia kutentha kwambiri, nthawi zambiri pakati pa 500 ° C ndi 550 ° C (932 ° F mpaka 1022 ° F).
Nitride Layer: Njira yopangira nitriding imapanga chosanjikiza cholimba pa mbiya ya screw nthawi zambiri kuyambira 0.1 mm mpaka 0.4 mm mu makulidwe.Chigawochi chimakhala ndi nitrides, makamaka gamma prime iron nitride (Fe4N).
Kukaniza Kuvala Kowonjezera: Nitriding imawonjezera kukana kwa mbiya ya screw, yomwe ndiyofunikira kwambiri pakutulutsa komwe wononga ndi mbiya zimavalidwa ndi ma polima ndi zowonjezera.The hard nitride layer imathandizira kukulitsa moyo wautumiki wa screw barrel, kuchepetsa nthawi yocheperako komanso mtengo wokonza.
Kulimbana ndi Kuwonongeka kwa Corrosion: Gawo la nitride limaperekanso kukana kwa dzimbiri kuchokera ku polima wosungunuka ndi zinthu zina zowononga zomwe zimakhalapo panthawi yotulutsa.Izi zimathandiza kuonetsetsa moyo wautali wa screw barrel ndikusunga magwiridwe antchito pakapita nthawi.
Kuchepetsa Kugundana: Kusanjikiza kosalala ndi kolimba kwa nitride kumachepetsa kukangana pakati pa wononga ndi mbiya, zomwe zimapangitsa kuti kutentha kuchepe komanso kutulutsa mphamvu kwamphamvu panthawi yotulutsa.Izi zitha kutanthauzira kuchepetsa kugwiritsa ntchito mphamvu komanso kupititsa patsogolo zokolola zonse.
Kusamutsa Kwabwinoko Kutentha: Nitriding imathandizira kutenthetsa kwa mbiya ya screw, kulola kusamutsa kutentha koyenera panthawi yosungunuka ndi kusakanikirana kwa polima.Izi zimathandiza kukwaniritsa kusungunuka kosasinthasintha komanso kodalirika, zomwe zimatsogolera ku khalidwe labwino la mankhwala.
Kuchepa Kwa Pulagi ndi Kusungunula Kusiyanasiyana: Pokhala ndi kulimbikira kukana kuvala komanso kusinthika kwapamwamba, mbiya ya nitrided screw simakonda kumangidwa kwazinthu, plugging, ndi kusiyanasiyana pakusungunuka.Izi zimabweretsa njira zokhazikika za extrusion, kuchepetsa nthawi yopumira, komanso kusasinthika kwazinthu.
Ndikofunikira kudziwa kuti zabwino zenizeni za mbiya ya nitrided screw zitha kusiyanasiyana kutengera ntchito, zinthu zomwe zikukonzedwa, komanso momwe zimakhalira.Kufunsana ndi wopanga migolo yodziwika bwino kapena woperekera zinthu kungathandize kudziwa ngati mbiya ya nitrided screw ndiye chisankho choyenera kwambiri pazosowa zanu zakutulutsa.
