I-casting coating iyinto eyisizayo ehlanganiswe ebusweni besikhunta noma i-core, edlala indima ebalulekile ekuthuthukiseni izinga eliphezulu le-castings.Izingcweti zakuqala zaseShayina, eminyakeni engaphezu kuka-3000 edlule, zilungiselele futhi zasebenzisa ngempumelelo i-casting coating, zenza umnikelo obalulekile ekuthuthukisweni kobuchwepheshe bokuphonsa.
Ngokuthuthuka kokukhiqiza nobuchwepheshe, izidingo zekhwalithi yokulingisa ziyanda usuku nosuku.Ukuze kuthuthukiswe ukuncintisana kwemikhiqizo yabo, izikhungo eziningi zizinikela ocwaningweni lwezingubo zokugqoka ngenxa yezinkinga ekukhiqizeni.
Okulandelayo, kafushane mayelana nokukhishwa kwe-casting yezinkinga eziningana.
Okokuqala, okuqukethwe okuqinile namandla okunamathela
Manje, ukunamathela okusetshenziselwa isihlabathi esiboshwe nge-resin kudinga okuqukethwe kwayo okuqinile okuphezulu namandla aphezulu, okubangelwa ikakhulukazi ukucatshangelwa okubili.
1. Zivumelanise nezici zesikhunta sesihlabathi
Esikhathini esedlule, isihlabathi sobumba esimanzi uhlobo lwesihlabathi hhayi upende, upende lwalusetshenziselwa kuphela uhlobo lobumba lwesihlabathi esomile.Ngenxa yamandla esihlabathi sobumba uhlobo elomile liphansi kakhulu, futhi ukwenza castings kubalulekile noma castings ezinkulu, imfuneko enamathela hhayi kuphela ukwakha ungqimba wokuzihlukanisa, futhi kudinga ngokungena ngokunyenyeza Casting enamathela ebusweni okulandelayo, best okubandakanya isihlabathi esingu-3 ~ 4, yenza ubuso besikhunta buthuthukisiwe, ngakho-ke, i-viscosity kapende ayikwazi ukuphakama kakhulu, okuqukethwe okuqinile akuphakeme kakhulu.
2. Cabangela ukonga ugesi, ukuvikelwa kwemvelo kanye nokunciphisa izindleko zokukhiqiza
Izithwali eziwuketshezi ezisetshenziswa embotsheni, ikakhulukazi amanzi notshwala.Iminyaka engu-20 70 ~ 80 isikhathi, esetshenzisiwe ayidingi ukomiswa noma ukuthungela, ingashisa ama-hydrocarbon esizukulwane se-chlorine, njenge-dichloromethane, njengomthwali wopende.Ngenxa yobuthi bayo, umthelela wayo omubi endaweni ezungezile njengoba ihwamuka emoyeni, kanye nezindleko zayo eziphakeme, manje ayisasetshenziswa kakhulu.
Okwesibili, izinto zokusetshenziswa ezisetshenziselwa ukunamathela
Kunezinhlobo eziningi zezinto zokusetshenziswa ezisetshenziswa ekujikeni, futhi zizokwengezwa njalo ngesisekelo sokuthuthukiswa kwemboni yezinto ezibonakalayo.
1. i-refractory aggregate
I-refractory aggregate iyisici esiyinhloko ekugqokeni, futhi ikhwalithi nokukhethwa kwayo kunethonya elikhulu ekusetshenzisweni komphumela wokugqoka.Ngesikhathi esifanayo, lapho sikhetha i-aggregate, kufanele futhi senze ukuhlaziya okubanzi ekuhlanzekeni kwezimboni kanye nomnotho.
2. umthwali,
Izithwali eziyinhloko ezisetshenziswa ekujikeni kwezingubo ngamanzi, utshwala nama-hydrocarbons ane-chlorine.Njengamanje, ngenxa yokucatshangelwa kwentengo kanye nezici zemvelo, ezisetshenziswa kakhulu ku-chlorine hydrocarbon njengomthwali we-coating, okujwayelekile kuwukunamathela emanzini kanye ne-alcohol based coating.
