Acid silica ramming zvinhu kuvira kwepakati pefrequency

Iyo asidhi silica ramming zvinhu zvepakati frequency choto inogadzirwa neyepamusoro-kuchena quartz uye yakasanganiswa silica seyakanyanya mbishi zvinhu, uye composite additives anoshandiswa senge sintering agents.

Ramming kuvaka ine acidic silica ramming zvinhu zvepakati frequency choto: Shandisa ichi chinhu uye wedzera nezve 4% yepombi mvura kusanganisa zvizere uye kutanga kuvaka.

Mushure mekugadzira ramming, bvisa iyo core mold, zvishoma nezvishoma bika ovheni, yakanyatsooma, uye zvishoma nezvishoma kupisa kana ovheni yakavhurwa isati yaiisa mukushandisa.
