Izitena zomlilo ezigqumayo ezikhaphukhaphu zisetyenziswa kakhulu kwinkqubo yokukhusela ii-oven. Ukusetyenziswa kwezitena zomlilo ezigqumayo ezikhaphukhaphu kufezekise iziphumo ezithile zokonga amandla kunye nokukhusela okusingqongileyo kwishishini lobushushu obuphezulu.
Isitena somlilo esikhaphukhaphu esilula sisixhobo sokukhusela esinobunzima obuphantsi, iimbobo eziphezulu, kunye nobushushu obuphantsi. Iimpawu zaso zobunzima obuphantsi kunye nobushushu obuphantsi zenza ukuba singathathelwa indawo kwii-oven zemizi-mveliso.
Inkqubo yokuvelisaisitena somlilo esikhaphukhaphu esilula
1. Linganisa izinto ezikrwada ngokwemilinganiselo efunekayo, gquba into nganye ibe yimpuphu. Yongeza amanzi kwisanti yesilika ukuze wenze i-slurry uze uyifudumeze kubushushu obuyi-45-50 ℃;
2. Yongeza izinto eziseleyo kwi-slurry uze udibanise. Emva kokuxuba ngokupheleleyo, galela i-slurry exutyiweyo kwi-mold uze uyifudumeze ukuya kuma-65-70 ° C ukuze iphume i-foam. Ubungakanani be-foam bukhulu kune-40% yenani lilonke. Emva kokuphuma i-foam, yigcine kuma-40 ° C iiyure ezi-2.
3. Emva kokuma ungashukumi, ngena kwigumbi lokufutha ukuze uphuze, ngoxinzelelo lokufutha oluyi-1.2MPa, ubushushu bokufutha obuyi-190 ℃, kunye nexesha lokufutha eliyiiyure ezili-9;
4. Ukutshisa okushushu okuphezulu, ubushushu obuyi-800 ℃.
