2. Kuramba kwakasimba kwekushisa kwepamusoro, mukukanda, tembiricha yechikamu chinosangana nemvura yesimbi kazhinji inosvika 1200 madhigirii celsius, uye jira rekukanda munzvimbo ino rinofanira kukwanisa kutsungirira kuyedzwa kwekushisa kwepamusoro.
3. Kunaka kwakanaka, kunowanzo shandiswa kugadzira machira ekukanda bentonite, ayo anodiwa anokwana anenge 325 mesh kana kupfuura.Zvimwe zvigadzirwa zvepamusoro zvinoda zviuru zvemaziso.
4. Kuchena kwepamusoro, kunowanzoshandiswa kugadzira machira ekukanda bentonite kunoda kuchena kwepamusoro, kusabvumirwa kuva netsvina yakawanda.Izvi zvinobatsira kukanganisa kunaka kweiyo cast workpiece nekuda kwekunyanya kusvibiswa mukukanda maitiro.
Muchidimbu, bentonite yefoundry coating bentonite yakakwirira kwazvo kupfuura yezvigadzirwa zvakawanda.Mukugadzirwa kwechokwadi, kune yakakwirira-yepamusoro sodium-based bentonite ine kuchena kwepamusoro uye inodhura lithium-based bentonite.Pasinei nechigadzirwa, chiyero che bentonite chinopedzwa neindasitiri iyi ichiri diki.

kushanda kwekuputira bentonite
1. Kuvandudza kumiswa uye thixotropy yejasi, uye kuwedzera nguva yekuchengetedza yejasi;
2. Kuvandudza simba rekuhwanda, brushability uye flatness yejasi;
3. Kuvandudza dhigirii refractory uye kushorwa kwemvura kwekuvhara uye kusungirirwa uye kusungirirwa kwechifukidzo chekuvhara;
4. Bentonite inogona kutsiva heavy calcium powder uye kuderedza mari yekugadzira kupfeka;
5. Kuvandudza kuderera kwekushisa kwekudzivirira kwekuputira.
Kupfekedza bentonite kunoshandisa
Bentonite inogona kuita se dispersant uye thickener mumajasi.Mukuwedzera, inobatawo chimwe chikamu mukunamatira kwekuputira, kukwanisa kwemvura, yakakwirira uye yakaderera kupisa kwekushisa, kutsetseka, etc. Parizvino, kushandiswa kwebentonite mukugadzirwa kwepende kunowedzera zvishoma nezvishoma.Nekuvandudzwa kwesainzi uye tekinoroji, kupfeka bentonite kuchashandiswa zvakanyanya.
Nzira yekusarudza pende bentonite
Kusarudzwa kwekuputira bentonite ndeyekuteerera kune akati wandei ma parameter ari kuchena, fineness, kuwedzera nguva.Bentonite yekuputira inosangana nemiganhu iyi inogona kusangana nezvinodiwa zvekupfeka panguva yekushandiswa.Zvinokurudzirwa kuti ushandise ivhu ace paint bentonite, ine unhu hwakanaka uye mutengo unonzwisisika
