Cast iAluminiyam/Isifudumezi sobhedu

Kwishishini leplastiki, esi sifudumezi siyinxalenye engundoqo yokufudumeza koomatshini bokubumba inaliti, ii-extruders kunye noomatshini bokubumba. Ngexesha lenkqubo yokubumba inaliti, inokutshisa ngokukhawuleza amasuntswana eplastiki kumbhobho ukuya kwindawo efanelekileyo etyhidiweyo, iqinisekisa ukusebenza kakuhle kunye nokuzinza kwesitofu sokubumba. Kwi-extruder, ukushisa kwe-screw kunye ne-barrel kunokulawulwa ngokuchanekileyo ukukhusela iplastiki ukuba ingaboli ngenxa yokushisa kwendawo okanye ukufudumeza okungalinganiyo, okunokubangela iziphene kwiimveliso. Xa isetyenziselwa ukubetha koomatshini bokubumba, inokubonelela ngobushushu obufanayo kunye nozinzile kwisikhunta, iqinisekisa ukuchaneka kokubumba kunye nomgangatho ophezulu weemveliso zeplastiki.

Kwinkalo yobunjineli bemichiza, izifudumezi zobhedu/i-aluminium ephosiweyo nazo zisebenza kakuhle kakhulu. Xa isetyenziswe kwiinqanawa zokusabela, inokufezekisa ukufudumeza okuchanekileyo kunye nozinzile ngokweemfuno ezingqongqo zeqondo lokushisa kwiindlela ezahlukeneyo zemichiza, ukukhuthaza inkqubela epheleleyo yeekhemikhali. Kwimibhobho enyibilikayo, inokuthintela ngokufanelekileyo ukunyibilika ekuqinisweni nasekunyukeni kwe-viscosity ngenxa yokuhla kweqondo lokushisa ngexesha lenkqubo yokuthutha, ukuqinisekisa ukuthuthwa kwezinto eziphathekayo kunye nokuphucula ukusebenza kakuhle kokuveliswa kweekhemikhali kunye nomgangatho wemveliso.

Izifudumezi ze-aluminiyam yobhedu/i-aluminiyam zithatha iityhubhu zokufudumeza zombane njengezona zinto ziphambili zokufudumeza kwaye zizifake kwizinto ezikumgangatho ophezulu zentsimbi ezifana ne-aluminiyam okanye ubhedu ngokusebenzisa iinkqubo zokugalela ezichanekileyo. Esi sakhiwo sihlukanisa ngokupheleleyo ucingo lokufudumeza emoyeni. Ngakolunye uhlangothi, iphakamisa kakhulu amandla okulwa ne-oxidation kunye nobomi benkonzo yento yokufudumeza, ngokufanelekileyo ukuthintela ukuhla kokusebenza kokufudumeza okanye umonakalo obangelwa yi-oxidation. Kwelinye icala, eyona conductivity ye-thermal yesinyithi efana ne-aluminiyam kunye nobhedu inika isifudumezi iimpawu zokuqina kunye nokuqina, ukubonelela ngokufudumeza okufanayo kunye nokutshintshana kobushushu obukhawulezayo, obunokudlulisa ubushushu ngokulinganayo kwindawo ekujoliswe kuyo ngexesha elifutshane.

Ukuhlangabezana neemfuno zeemeko ezikhethekileyo zokusebenza, i-heater yenzelwe kunye nokwandiswa kokusebenza okuguquguqukayo. Kwiindawo ezikhethekileyo ezifana nezinokutsha kunye neziqhumayo, iibhokisi zesiphambuka ezinobungqina bokudubula ziyamkelwa, zithobela ngokungqongqo imigangatho yokhuseleko olunoqhushumbo ukuze kupheliswe iingozi ezinokubakho zokhuseleko ezibangelwa ziintlantsi zombane ezivela kumthombo. Kwiimeko ezineemfuno ze-insulation, i-high-effect-efficiency layers inokuthi iqwalaselwe ukunciphisa ukulahleka kobushushu, ukusetyenziswa kwamandla aphantsi, kwaye kwangaxeshanye kugcinwe ubushushu bomphezulu besixhobo ngaphakathi koluhlu olukhuselekileyo, ukuphucula ukhuseleko lokusebenza.
