Kwinkqubo yokucubungula nokuvelisa isikhunta, isiseko segranite sisebenza njenge "stabilizer" yezixhobo, sichaphazela ngokuthe ngqo ukuchaneka kokufakwa kwesikhunta kunye nomgangatho wemveliso. Ngoko ke, ungayikhetha njani isiseko segranite esifanelekileyo?
Okokuqala, ukuchaneka yeyona nto ibalulekileyo. Ukufakelwa kwesikhunta kuneemfuno ezichanekileyo kakhulu. Ingqwalasela ekhethekileyo kufuneka inikwe ekuthe tyaba nasekuthe tyeni kwesiseko. Isiseko segranite esisemgangathweni ophezulu sithe tyaba ngaphakathi kwe-±0.5μm/m kunye nempazamo yokuthe tye engadluli kwi-±0.3μm/m. Njengokwakha ngeebhloko, xa isiseko sithe tyaba, kokukhona isikhunta siya kufakelwa ngokuchanekileyo, kwaye ubukhulu beemveliso eziveliswayo buya kuhambelana ngakumbi nemigangatho.
Okwesibini, umthamo wokuthwala awunakutyeshelwa. Ubunzima bemifucu eyahlukeneyo buyahluka kakhulu. I-mold encinci yokujova inobunzima obuziikhilogram ezimbalwa kuphela, ngelixa i-mold enkulu yokuphosa i-die-casting inobunzima beetoni ezininzi. Xa ukhetha isiseko, kubalulekile ukulinganisa umthamo wokuthwala umthwalo ngokusekelwe kubunzima be-mold kwaye ugcine umda wokhuseleko we-20% ukuya kwi-30%, njengokuthenga ishelufu enomthamo omkhulu wokuthwala umthwalo ukuthintela ukugqithisa umthwalo kunye nokuguquguquka.
Ukongeza, ukungcangcazela kwenzeka ngexesha lokucubungula isikhunta, nto leyo efuna ukuba isiseko sibe nokusebenza kakuhle kokungcangcazela. I-Granite ngokwendalo ineempawu ezintle zokungcangcazela kwaye inokufunxa ngaphezulu kwe-90% yokungcangcazela okuphezulu. Ukukhetha isiseko esinomlinganiselo wokungcangcazela ongaphezulu kwe-0.02 kunokunciphisa ngempumelelo amabala okuphaphazela kumphezulu wesikhunta kwaye kwenze umphezulu wemveliso ube buthelezi.
Kwakhona, ukuhambelana kofakelo kubaluleke kakhulu. Ngokwendlela yokulungisa isikhunta, khetha isiseko esineendawo ezifanelekileyo ze-T kunye nemingxunya enemisonto. Ukuba yisikhunta esinemilo ekhethekileyo, isiseko esinobume obungacwangciswanga naso singenziwa ngokwezifiso. Kwangaxeshanye, xa kujongwa imeko yokucubungula, ukuba siza kudibana nezinto zeekhemikhali ezifana ne-coolant, i-granite eye yafumana unyango lokungangeni kwamanzi kufuneka ikhethwe ukuthintela ukuba isiseko singabi namanzi.
Ukuba nje uyaziqonda ezi ngongoma zibalulekileyo, ungakhetha isiseko segranite esifanelekileyo kwizixhobo zokufakela isikhunta, ukuqinisekisa imveliso esebenzayo!
