Umgangatho ophezulu we-nitrided screw kunye nebhere
Inkqubo yeNitriding: I-Nitriding lunyango lokuqina komphezulu apho initrogen isasazwa kumphezulu wemathiriyeli ukwenza umaleko oqinileyo we-nitride.Le nkqubo idla ngokubandakanya ukufudumeza i-screw barrel kwindawo elawulwayo yegesi ye-ammonia kumaqondo obushushu aphezulu, phakathi kwe-500 ° C kunye ne-550 ° C (932 ° F ukuya ku-1022 ° F).
I-Nitride Layer: Inkqubo ye-nitriding yenza umaleko womphezulu oqinileyo kwi-screw barrel oqhele ukuqala ukusuka kwi-0.1 mm ukuya kwi-0.4 mm ubukhulu.Lo maleko uqulathe ii-nitrides, ingakumbi i-gamma prime iron nitride (Fe4N).
Ukuchasana nokuNxibelelana okuYomeleziweyo: I-Nitriding yonyusa kakhulu ukuxhathisa kokunxitywa kwe-screw barrel, eyona nto ibalulekileyo kwiinkqubo ze-extrusion apho i-screw kunye ne-barrel iphantsi kokunxitywa kwe-abrasive evela kwi-polymer kunye nezongezo.Umaleko onzima we-nitride unceda ukwandisa ubomi benkonzo ye-screw barrel, ukunciphisa ixesha lokuphumla kunye neendleko zokugcina.
Ukuchasana nokuNcitshiswa kwe-Corrosion: Umaleko we-nitride ukwabonelela ngokuphucuka kokumelana nokubola kwipolymer etyhidiweyo kunye nezinye izinto ezidlayo ezikhoyo ngexesha lenkqubo yokukhupha.Oku kunceda ukuqinisekisa ubomi obude be-screw barrel kunye nokugcina ukusebenza okungaguqukiyo ngexesha.
I-Friction eNcitshisiweyo: Umaleko we-nitride ogudileyo kunye nolukhuni unciphisa ukungqubana phakathi kwe-screw kunye ne-barrel, okukhokelela ekuveliseni ubushushu obuncinci kunye nokusebenza kakuhle kwamandla ngexesha lenkqubo yokukhupha.Oku kunokutolika ekunciphiseni ukusetyenziswa kwamandla kunye nokuphuculwa kwemveliso jikelele.
Ukutshintshwa kobushushu obungcono: I-Nitriding iphucula ukuqhutyelwa kwe-thermal ye-screw barrel, ivumela ukuhanjiswa kobushushu okusebenzayo ngexesha lokunyibilika kunye nokuxuba i-polymer.Oku kunceda ukufezekisa ukunyibilika okuhambelanayo kunye nokuthembekileyo, okukhokelela kumgangatho ongcono wemveliso.
UkuPlaga okuncinci kunye nokwahluka okunyibilikayo: Ngokuxhathisa ukunxitywa okuphuculweyo kunye neempawu eziphuculweyo zomgangatho, i-nitrided screw barrel ayithandeki kangako ekwakhiweni kwezinto, ukuplaga, kunye nokwahluka ekunyibilikeni.Oku kubangela iinkqubo ezizinzileyo ze-extrusion, ukunciphisa ixesha lokunciphisa, kunye nokuphucula ukuhambelana kwemveliso.
Kubalulekile ukuqaphela ukuba izibonelelo ezithile ze-nitrided screw barrel zinokwahluka ngokuxhomekeke kwisicelo, imathiriyeli eqhutyelwayo, kunye neemeko zenkqubo.Ukubonisana nomenzi webhareli othembekileyo okanye umboneleli kunokunceda ukufumanisa ukuba i-nitrided screw barrel lolona khetho lufanelekileyo kwiimfuno zakho ezithile ze-extrusion.
