I-Bentonite yokugqoka
Izici ze-bentonite zokugqoka izingubo
1. Ukusebenza kahle kokumiswa, ekufakeni i-casting coatings, umsebenzi oyinhloko we-bentonite ukumiswa, okungenza izici ze-casting coating ngokwazo zifanane.Ngale ndlela, ukuqedwa okungaphezulu kwe-casting workpiece kungaqinisekiswa.
2. Ukumelana nokushisa okuphezulu okuqinile, enqubweni yokuphonsa, izinga lokushisa lengxenye ethinta uketshezi lwensimbi ngokuvamile lifinyelela ku-1200 degrees Celsius, futhi ukumbozwa kokuphonsa kule ndawo kufanele kukwazi ukumelana nokuhlolwa kokushisa okuphezulu.
3. Ubuhle obuhle, ngokuvamile obusetshenziselwa ukwenza i-casting coatings i-bentonite, izidingo zayo zokucwenga okungenani ziyi-325 mesh noma ngaphezulu.Eminye imikhiqizo esezingeni eliphezulu idinga izinkulungwane zamehlo.
4. Ukuhlanzeka okuphezulu, okuvame ukusetshenziselwa ukwenza i-casting coatings bentonite kudinga ukuhlanzeka okuphezulu, okungavunyelwe ukuba nokungcola okuningi.Lokhu kulungele ukuthikameza ikhwalithi yesicucu sokusebenza ngenxa yokungcola okweqile enqubweni yokulingisa.
Ngamafuphi, i-bentonite ye-foundry coating bentonite iphakeme kakhulu kunemikhiqizo evamile.Ekukhiqizeni kwangempela, kukhona i-bentonite esekelwe kwi-sodium ephezulu enokuhlanzeka okuphezulu kanye ne-bentonite esekelwe e-lithium ebizayo.Kungakhathaliseki ukuthi umkhiqizo unjani, inani le-bentonite elidliwe yilo mboni lisencane kakhulu.

| I-calcium-based | >30 | > 60 | >10 | 6.5-7.5 | <10 | >180 |
ukusebenza kokugqoka i-bentonite
1. Thuthukisa ukumiswa kanye ne-thixotropy yokugqoka, futhi ukwandise isikhathi sokugcina sokugqoka;
2. Thuthukisa amandla okucasha, ukuxubha kanye nokugcwala kwe-coating;
3. Thuthukisa i-refractory degree kanye nokuphikiswa kwamanzi kwe-coating kanye nokunamathela nokunamathela kokugqoka okunamathelayo;
4. I-Bentonite ingakwazi ukufaka esikhundleni se-calcium powder esindayo futhi inciphise izindleko zokukhiqiza ukugqoka;
5. Thuthukisa ukumelana nokushisa okuphansi kwe-coating.
Ukusebenzisa i-bentonite yokugqoka
I-Bentonite ingakwazi ukusebenza njenge-dispersant kanye ne-thickener in coatings.Ngaphezu kwalokho, iphinde idlale indima ethile ekunamatheleni kokugqoka, ikhono lokungangeni manzi, ukumelana nokushisa okuphezulu nokuphansi, ukushelela, njll. Njengamanje, ukusetshenziswa kwe-bentonite ekukhiqizeni upende kujula kancane kancane.Ngokuthuthukiswa kwesayensi nobuchwepheshe, i-bentonite yokugcoba izosetshenziswa kabanzi.
Indlela yokukhetha i-bentonite yepende
Ukukhethwa kwe-coating bentonite ukunaka imingcele eminingana kukhona ubumhlophe, ubucwebe, izikhathi zokunwetshwa.I-Bentonite yezingubo ezihlangabezana nale mingcele zingahlangabezana nezidingo eziyisisekelo zokugqoka ngesikhathi sokusetshenziswa.Kunconywa ukuthi usebenzise inhlabathi ye-ace paint bentonite, enekhwalithi enhle kakhulu kanye nentengo enengqondo
