Girazi microbeads rudzi rutsva rwe silicate zvinhu zvakagadzirwa mumakumi maviri emakore apfuura. Kune marudzi akawanda uye zvakasiyana-siyana zvekushandisa. Vanhu vari kuramba vachiteerera. Nzira yekugadzira inopfupikiswa sezvinotevera. Nzira dzekugadzira magirazi egirazi dzinogona kukamurwa kuita zvikamu zviviri: nzira yehupfu uye nzira yekunyungudika. Iyo nzira yehupfu ndeyekupwanya girazi muzvikamu zvinodikanwa, mushure mekusefa, pane imwe tembiricha, kuburikidza nenzvimbo yekudziya yunifomu, zvimedu zvegirazi zvinonyungudutswa, uye ma microbeads anoumbwa pasi pekuita kwekushushikana kwepasi. Iyo nzira yekunyungudutsa inoshandisa yakanyanya-kumhanya kuyerera kwemhepo kuparadzira girazi mvura mumadonhwe egirazi, ayo anoumba microbeads nekuda kwekunetsana kwepasi. Kupisa nzira: Kune girazi rine huwandu kana hwepamusoro kunyunguduka tembiricha, gasi kupisa kana oxyacetylene murazvo uye oxyhydrogen murazvo wekudziya unogona kushandiswa; yegirazi ine tembiricha yakanyungudika, DC arc plasma mudziyo inogona kushandiswa kupisa. Nzira yehupfu Pakutanga, nzira yakawanda yehupfu yakashandiswa. Iyo girazi rehupfu sehupfu hwakaiswa mudura ndokuyerera kuenda kunzvimbo inopisa yehupfu hwegasi. Magirazi mabhero anodzorwa nemurazvo wakasimba pano uye anosundirwa mukamuri huru yekuwedzera yechishandiso. Kuburikidza nekudziya kwemurazvo, magirazi egirazi anonyungudika ipapo ipapo. Ipapo zvimedu zvinokurumidza kuderedza viscosity uye zvinoumbwa kuita yakanaka spherical shape inosangana nezvinodiwa pasi pechiito chekushushikana kwepasi.
