Umthengisi wenhlabathi we-Foundry bentonite
Ukusakaza i-bentonite esekelwe kwi-sodiumiyisibopho esidingekayo sokubumba isikhunta sesihlabathi, futhi ukukhethwa kwe-bentonite efanelekile ngokusho kwekhwalithi yokukhipha akukwazi kuphela ukuqinisekisa ikhwalithi, kodwa futhi kunciphise izindleko.Ngakho-ke, ukukhetha i-bentonite efanele ngokuya ngekhwalithi yokubunjwa yiyona nto ehamba phambili yomsebenzi wesikhunta sesihlabathi.
Izimpawu nezici:
Lo mkhiqizo uyimpushana emhlophe noma ephuzi ekhanyayo, impushana ebomvu yomhlaba.
Isigaba somkhiqizo:
(1) Izinga le-sodium: lingele-high-thermal stability casting ne-sodium-based bentonite, lo mkhiqizo ulungele ukukhishwa okunemba okuphezulu,ukulingisa ngokunemba, ngokufaka okuncane (ngaphansi kuka-5%), ukucindezela okumanzi, amandla aphezulu okushisa nokushisa okumanzi, ukungena komoya, ukusebenza okuhle kokusetshenziswa kabusha, kuyadingeka ekusakazeni okunembayo okuphezulu, abakhiqizi bokusakaza ngokunemba.
(2) Izinga lesibili le-sodium: lingele-bentonite ejwayelekile esekelwe ku-sodium, lo mkhiqizo ulungele ukubunjwa okunembayo, ukulingisa okuvamile, okokufaka okumaphakathi (5-8%), ukungena komoya, ukusebenziseka kabusha okuhle, ukukhetha okuyinhloko kokusakazwa okunembayo. , abakhiqizi abajwayelekile be-casting.is umkhiqizo uyimpushana ephuzi emhlophe noma ekhanyayo, impushana ebomvu yomhlaba.
3) I-calcium-based: Ingowe-bentonite ejwayelekile esekelwe ku-calcium, lo mkhiqizo ulungele ukulingwa okuvamile, ukulingwa okungekuhle, futhi ungumkhiqizo okhethwayo wokulingisa ama-rough.
Ukupakisha nokugcina:
Kusetshenziswa ifilimu yepulasitiki yangaphakathi, isikhwama esilukiwe sangaphandle sipakishwa ngezingqimba ezimbili noma sipakishwe ngokwezidingo zomsebenzisi, kanti isisindo sokupakisha singu-400.25kg, 500.25kg, 10001.0kg.

I-bentonite esekwe ku-sodium yokusakaza
I-Bentonite iyibumba elikhethekile lamaminerali eline-viscosity, ukunwetshwa, i-lubricity, ukumuncwa kwamanzi kanye ne-thixotropy nezinye izici, ukusetshenziswa kuye kwahlanganisa izinto zokuphonsa, ama-pellets e-metallurgical, ama-chemical coatings, imboni yokumba udaka kanye nokukhanya kanye nezolimo emikhakheni ehlukahlukene, kamuva ngenxa yobubanzi bayo. ukusetshenziswa, okwaziwa ngokuthi "inhlabathi yendawo yonke", leli phepha lixoxa ngokuyinhloko ngokusetshenziswa kanye nendima ye-bentonite ekubunjweni.
Ukwakheka kwesakhiwo se-bentonite
I-Bentonite yenziwe nge-montmorillonite ngokusho kwesakhiwo sayo se-crystal, ngoba i-crystal yayo eyingqayizivele inokunamathela okuqinile ngemva kokumuncwa kwamanzi, ngakho-ke isetshenziswa kabanzi ekukhipheni isihlabathi, isihlabathi sihlanganiswe ndawonye ukuze senze amandla amanzi kanye ne-plasticity, namandla omile ngemva kokumisa.Ngemuva kokuthi i-bentonite isomile, ukuhlangana kwayo kungabuyiselwa ngemva kokwengeza amanzi.
