Chiedza Weight Silica Insulation Brick inotora zvakakamurwa zvakakamurwa silica ore seyakagadzirwa zvinhu. iyo yakakosha particle size haina kupfuura 1mm, imomo inopfuura 90% particle size isingasviki 0.5mm. silicate insulation zvidhinha inogadzirwa nekuwedzera chinhu chinopfuta mukuremedza kana kutora gasi bubble nzira yekugadzira porous chimiro kuburikidza nekupfura, silicate insulation zvidhinha zvakare inogona kuitwa isina kupiswa chigadzirwa.
Light Weight Silica Insulation Brick inoisa mbishi uye mvura mumudziyo wekukanyira zvinoenderana nechimwe chikamu uye wozokanya mudhaka, kuumba dhaka kuita zvidhinha kuburikidza nekuumbwa nemuchina kana manpower. wobva waomesa zvidhinha kusvikira mvura yakasara yakaderera kupfuura 0.5%, iyo inodzivirira kuwedzera kwevhoriyamu kubva pakushandurwa kwekristaro yeSiO2 uye kupisa zvidhinha zvakaumbwa mukupisa kwepamusoro.
