Isifudumezi seAluminiyam/seCopper

Kwishishini leplastiki, esi heater sisixhobo esiphambili sokufudumeza kwiimashini zokubumba ngenaliti, ii-extruders kunye neemashini zokubumba nge-blow molding. Ngexesha lenkqubo yokubumba ngenaliti, sinokufudumeza ngokukhawuleza amasuntswana eplastiki kwi-barrel ukuya kwimeko efanelekileyo yokunyibilika, ukuqinisekisa ukusebenza kakuhle kunye nokuzinza kwe-injection molding. Kwi-extruder, ubushushu be-screw kunye ne-barrel bunokulawulwa ngokuchanekileyo ukuthintela iplastiki ekuboleni ngenxa yokushisa kakhulu kwendawo okanye ukufudumala okungalinganiyo, okunokubangela iziphene kwiimveliso. Xa isetyenziswa kwiimashini zokubumba nge-blow molding, inokubonelela ngobushushu obufanayo nobuzinzileyo kwi-mold, iqinisekisa ukuchaneka kokwakheka kunye nomgangatho womphezulu weemveliso zeplastiki.

Kwicandelo lobunjineli beekhemikhali, izifudumezi ze-aluminium ezenziwe nge-copper/cast nazo zisebenza kakuhle kakhulu. Xa zisetyenziswa kwimikhumbi ye-reaction, zinokufikelela ekufudumaleni okuchanekileyo nokuzinzileyo ngokweemfuno zobushushu ezingqongqo zeempendulo ezahlukeneyo zeekhemikhali, zikhuthaza inkqubela epheleleyo yeempendulo zeekhemikhali. Kwimibhobho enyibilikayo, inokuthintela ngempumelelo ukunyibilika ekuqineni nasekunyukeni kwe-viscosity ngenxa yokwehla kobushushu ngexesha lenkqubo yokuthutha, iqinisekise ukuthuthwa kwezinto ezithambileyo kunye nokuphucula ukusebenza kakuhle kwemveliso yeekhemikhali kunye nomgangatho wemveliso.

Izifudumezi ze-aluminium ezixotyulweyo/ezixotyulweyo zithatha iityhubhu zokufudumeza zombane njengezinto eziphambili zokufudumeza kwaye zizifaka kwizinto zesinyithi ezikumgangatho ophezulu ezifana ne-aluminium okanye ubhedu ngeenkqubo zokuxotyulwa ezichanekileyo. Olu lwakhiwo luhlukanisa ngokupheleleyo ucingo lokufudumeza emoyeni. Kwelinye icala, luphucula kakhulu amandla okulwa ne-oxidation kunye nobomi benkonzo yento yokufudumeza, luthintela ngempumelelo ukwehla kokusebenza kakuhle kokufudumeza okanye umonakalo wento obangelwa yi-oxidation. Kwelinye icala, ukuhanjiswa kobushushu okuhle kakhulu kweentsimbi ezifana ne-aluminium kunye nobhedu kunika i-heater iimpawu zokuba yomelele kwaye ihlale ixesha elide, ibonelela ngokufudumeza okufanayo kunye nokutshintshiselana kobushushu ngokukhawuleza, okunokudlulisa ubushushu ngokulinganayo kwindawo ekujoliswe kuyo ngexesha elifutshane.

Ukuze kuhlangatyezwane neemfuno zeemeko zokusebenza ezikhethekileyo, isifudumezi senzelwe ukwandiswa okuguquguqukayo kokusebenza. Kwiindawo ezikhethekileyo ezifana nezo zitshayo neziqhumayo, kusetyenziswa iibhokisi zokudibanisa ezingoochwephesha ezingaqhumiyo, ezinamathela ngokungqongqo kwimigangatho yokhuseleko engaqhumiyo ukuze kupheliswe iingozi ezinokubakho ezibangelwa ziintlantsi zombane ezivela kumthombo. Kwiimeko ezineemfuno zobushushu, iileya zobushushu ezisebenzayo kakhulu nazo zinokucwangciswa ukunciphisa ukulahleka kobushushu, ukunciphisa ukusetyenziswa kwamandla, kwaye kwangaxeshanye kugcinwe ubushushu bomphezulu wezixhobo ngaphakathi koluhlu olukhuselekileyo, oko kuphucula ukhuseleko lokusebenza.
