Foundry bentonite tov av tswv
Casting sodium-based bentoniteyog ib qho tsim nyog binder rau casting xuab zeb pwm, thiab kev xaiv ntawm bentonite haum raws li qhov zoo ntawm casting tsis tsuas yog xyuas kom zoo, tab sis kuj txo nqi.Yog li ntawd, xaiv txoj cai bentonite raws li qhov zoo ntawm cov casting yog qhov tseem ceeb tshaj plaws ntawm cov xuab zeb pwm ua haujlwm.
Cov yam ntxwv thiab cov yam ntxwv:
Cov khoom no yog dawb los yog lub teeb daj hmoov, lub ntiaj teb liab hmoov.
Cov khoom lag luam:
(1) Sodium qib: belongs rau siab thermal stability casting nrog sodium-based bentonite, cov khoom no yog tsim rau high-precision castings,precision castings, nrog cov tswv yim tsawg (tsawg dua 5%), ntub dej, siab thermal thiab ntub tensile zog, huab cua permeability, zoo reusability kev ua tau zoo, yog ib tug yuav tsum rau high-precision castings, precision casting manufacturers.
(2) Sodium theem nrab: belongs rau qhov zoo tib yam casting sodium-based bentonite, cov khoom no yog tsim rau precision castings, zoo tib yam castings, nrog nruab nrab input (5-8%), huab cua permeability, zoo reusability, yog lub ntsiab kev xaiv ntawm precision castings. , zoo tib yam casting manufacturers.is khoom yog dawb los yog lub teeb daj hmoov, lub ntiaj teb liab hmoov.
3) Calcium-raws li: Nws belongs rau qhov zoo tib yam casting calcium-raws li bentonite, cov khoom no yog tsim rau zoo tib yam castings, ntxhib castings, thiab yog cov khoom nyiam rau ntxhib castings.
Ntim thiab khaws cia:
Cov yas zaj duab xis sab hauv yog siv, lub hnab woven sab nrauv yog ntim rau hauv ob txheej los yog ntim raws li cov neeg siv yuav tsum tau, thiab lub ntim hnyav yog 400.25kg, 500.25kg, 10001.0kg.

Sodium-based bentonite rau casting
Bentonite yog cov av nplaum tshwj xeeb nrog cov viscosity, nthuav dav, lubricity, nqus dej thiab thixotropy thiab lwm yam ntxwv, kev siv tau npog cov ntaub ntawv casting, metallurgical pellets, tshuaj coatings, drilling av nkos thiab lub teeb kev lag luam thiab kev ua liaj ua teb hauv ntau yam, tom qab ntawd vim nws qhov dav. siv, hu ua "universal av", daim ntawv no tsuas yog tham txog daim ntawv thov thiab lub luag haujlwm ntawm bentonite hauv casting.
Cov qauv tsim ntawm bentonite
Bentonite yog tsim los ntawm montmorillonite raws li nws cov qauv siv lead ua, vim hais tias nws cov cim crystal muaj zog adhesion tom qab dej nqus, yog li nws yog dav siv hauv casting xuab zeb, cov xuab zeb yog sib koom ua ke los tsim lub zog ntub thiab plasticity, thiab lub zog qhuav tom qab ziab.Tom qab bentonite qhuav lawm, nws cov cohesion tuaj yeem rov qab tau tom qab ntxiv dej.
