Sodium-based bentonite hmoov: 1. Nyob rau hauv lub tshuab casting kev lag luam, nws yuav siv tau raws li casting xuab zeb thiab binder, uas yuav kov yeej lub "sand inclusion" thiab "peeling" phenomena ntawm castings, txo cov seem ntawm castings, thiab xyuas kom meej qhov tseeb thiab tiav ntawm castings. .2. Hauv kev lag luam ntawv, nws yog siv los ua cov ntawv sau los txhim kho qhov ci ntawm daim ntawv.3. Siv lub zog adhesion kev ua tau zoo ntawm cov khoom no, nws yog siv rau zus tau tej cov dawb latex, pem teb kua nplaum, muab tshuaj txhuam, thiab lwm yam raws li ib tug thickening thiab anti- nag lossis daus additive rau dej-raws li txheej.5. Nyob rau tib lub sijhawm, siv nws zoo heev dispersion thiab expansion, siab pulping tus nqi, tsis tshua muaj dej poob, colloidal zog thiab shear dilution muaj peev xwm, nws yuav siv tau raws li sodium av rau drilling av nkos.
Calcium-based bentonite feem ntau yog siv los ua cov ntaub ntawv hauv cov xuab zeb casting thiab thermal rwb thaiv tsev cov ntaub ntawv;radioactive pov tseg absorbent;Tshuaj tua kab raws li cov cab kuj los yog thinners, tshuaj tua kab;Drilling av nkos flushing kua.Cov yam ntxwv ntawm calcium-based bentonite: 1. Txhim kho ntub compressive zog, kub thiab av noo tensile zog thiab crushing Performance index.2. Txo cov dej noo ntawm molding xuab zeb thiab txo cov casting defects tshwm sim los ntawm cov dej noo ntau dhau.3. Txhim kho cov huab cua permeability ntawm ntub molding xuab zeb, tsis tshua muaj roj tiam, thiab tiv thaiv porosity hauv castings.4. Nws muaj zoo toughness, plasticity thiab wettability ntawm cov xuab zeb nto, yog li ntawd lub casting nto yog ntom thiab du, lub zuag qhia tag nrho pwm lub zog yog uniform, thiab cov pwm pib kev ua tau zoo.7. Ua kom cov fluidity ntawm molding xuab zeb, uas tuaj yeem ua rau lub sijhawm sib xyaw ntawm cov xuab zeb thiab txhim kho cov khoom siv tus nqi.8. Zoo collapsibility, yooj yim los ntxuav cov xuab zeb, luv luv txhaj blasting lub sij hawm, txhim kho kev txhaj tshuaj blasting efficiency.9. Txhim kho lub zog qhuav thiab kub thiab ntub tensile lub zog nyob rau hauv thaum ntxov theem ntawm ntub pouring, txo casting defects xws li xuab zeb ntxuav, xuab zeb inclusion, xuab zeb qhov, pores, thiab lwm yam. thiab muaj cov txiaj ntsig ncaj qha kev lag luam zoo dua thiab cov txiaj ntsig kev lag luam zoo.
