Iinkcukacha zenkqubo yokuvelisa izitena eziphikisayo
Iinkcukacha zenkqubo yemveliso ye izitena ezikhanyelayo:
Izitena eziphikisayo zizitena ezenziwe ngezinto ezinqabileyo (i-aggregates), izinto ezincedisayo kunye nokongeza izibophelelo ngomlinganiselo othile ngokuxuba, ukwenza i-pi, ukomisa kunye nezinye iinkqubo kwaye emva koko i-sintered okanye i-non-sintered.
Ukukhetha izinto ezikrwada-ukulungiselela umgubo (ukutyunyuzwa, ukutyunyuzwa, ukuhluzwa) -izithako ezilungelelanisiweyo-ukuxuba-pi ukubumba-ukomisa-sintering-ukuhlola-ukupakishwa
1. Ekubeni zininzi izinto ezisetyenziswayo zokwenza izitena eziphikisayo, ukhetho lwezinto ezibonakalayo kukumisela ukuba zeziphi iinkcukacha zezitena eziphikisayo ezenziweyo kunye nokukhusela izinto eziluhlaza. Qaphela apha umxholo wezinto eziluhlaza kunye nomxholo we-particle kunye nobukhulu bezithako.
2. Inkqubo yokulungiselela umgubo kukuqhubela phambili ukutyumza kunye nokukhusela imathiriyeli ekrwada ukuhlangabezana neemfuno zemveliso.
3. Izithako ezilinganayo kukulungiswa okuchanekileyo kwezinto eziluhlaza, izibophelelo kunye namanzi ngomlinganiselo othile ukuqinisekisa ukusebenza kwezitena eziphikisayo ezisetyenziswayo.
4. Ukuxuba kukudibanisa ngokulinganayo izinto eziluhlaza, i-binder kunye namanzi ukwenza udaka lube yinto efanayo.
5. Emva kokuxuba, udaka kufuneka luvunyelwe ukuba lume ixesha elithile, ukwenzela ukuba udaka lufanane ngokupheleleyo kwaye lubunjwe, olwandisa iplastiki yodaka kunye namandla emveliso ephikisayo.
6. Ukubunjwa kukubeka udaka kwi-mold emiselweyo ukumisela imilo, ubukhulu, ubuninzi kunye namandla emveliso.
7. Isitena esibunjiweyo sinomswakama ophezulu, kwaye kufuneka somiswe ngaphambi kokudubula ukuze kugwenywe ukuqhekeka okubangelwa ukufudumeza okugqithiseleyo ngokukhawuleza komswakama ngexesha lokudubula.
8. Emva kokuba izitena zomisiwe, umthamo wokufuma kufuneka uncitshiswe ube yi-2% yokungena kwi-oven ukuze utshise. Inkqubo ye-sintering inokwenza izitena zidibanise, ukunyuka kwamandla kunye nokuzinza kumthamo, kwaye zibe zizitena eziphikisayo ezineenkcukacha ezithile.
9. Emva kokuba izitena ezivuthayo ezivuthayo zikhutshwe kwi-oven, zinokufakwa kwindawo yokugcina emva kokuhlolwa ngumhloli wekhwalithi.
