Izikulufu ze-nitrided zekhwalithi ephezulu kanye nomgqomo
Inqubo ye-Nitriding: I-Nitriding iwukwelashwa kokuqina kwendawo lapho i-nitrogen isakazwa khona endaweni yokwenza ungqimba lwe-nitride oluqinile.Le nqubo ngokuvamile ihlanganisa ukushisisa umphongolo wesikulufu endaweni elawulwayo yegesi ye-ammonia emazingeni okushisa aphezulu, ngokuvamile phakathi kuka-500°C no-550°C (932°F kuya ku-1022°F).
I-Nitride Layer: Inqubo ye-nitriding yakha isendlalelo sendawo eqinile emgqonyeni wesikulufu ngokuvamile osukela ku-0.1 mm kuya ku-0.4 mm ubukhulu.Lesi sendlalelo siqukethe ama-nitrides, ikakhulukazi i-gamma prime iron nitride (Fe4N).
Ukumelana Okuthuthukisiwe Kwe-Wear: I-Nitriding inyusa kakhulu ukumelana nokugqokwa komgqomo wesikulufu, okubalulekile ezinqubweni zokukhipha lapho isikulufu nomgqomo kuthonywa ukuguga okuphuma ku-polymer nezithasiselo.Isendlalelo se-nitride esiqinile sisiza ukunweba impilo yesevisi ye-screw barrel, ukunciphisa isikhathi sokuphumula kanye nezindleko zokuyilungisa.
Ukumelana Nokugqwala Okuthuthukisiwe: Ungqimba lwe-nitride futhi lunikeza ukumelana okuthuthukisiwe kokugqwala okuvela ku-polymer encibilikisiwe nezinye izakhi ezibolayo ezikhona phakathi nenqubo yokukhipha.Lokhu kusiza ukuqinisekisa ubude besikhathi somgqomo wesikulufu nokugcina ukusebenza okungaguquki ngokuhamba kwesikhathi.
I-Friction Encishisiwe: Isendlalelo se-nitride esibushelelezi nesiqinile sinciphisa ukungqubuzana phakathi kwesikulufu nomgqomo, okuholela ekukhiqizeni ukushisa okuncane nokusebenza kahle kwamandla ngesikhathi senqubo yokukhipha.Lokhu kungahumushela ekusetshenzisweni kwamandla okuphansi kanye nokukhiqiza okuthuthukisiwe kukonke.
Ukudlulisa Ukushisa Okungcono: I-Nitriding ithuthukisa ukuqhutshwa kokushisa komgqomo wesikulufu, okuvumela ukudluliswa kokushisa okuphumelelayo ngesikhathi sokuncibilika nokuxutshwa kwe-polymer.Lokhu kusiza ukuzuza ukuncibilika okungaguquki nokuthembekile, okuholela kukhwalithi yomkhiqizo engcono.
Ukuhlukahluka Okuncane Kokuxhuma Nokuncibilika: Ngokumelana okuthuthukisiwe kokugqokwa kanye nezakhiwo ezithuthukisiwe zangaphezulu, umphongolo wesikulufa se-nitrided awuthambekele kakhulu ekwakhiweni kwezinto ezibonakalayo, ukuxhuma, nokuhluka ekuncibilikeni.Lokhu kubangela izinqubo ezizinze kakhudlwana ze-extrusion, ukunciphisa isikhathi sokuphumula, kanye nokuvumelana komkhiqizo okuthuthukisiwe.
Kubalulekile ukuqaphela ukuthi izinzuzo ezithile ze-nitrided screw barrel zingahluka kuye ngohlelo lokusebenza, impahla ecutshungulwayo, kanye nezimo zenqubo.Ukubonisana nomkhiqizi wemiphongolo yesikulufa ohlonishwayo noma umphakeli kungasiza ekunqumeni ukuthi umphongolo wesikulufa we-nitrided uwukukhetha okulungele yini izidingo zakho ezithize ze-extrusion.
