Iyo itsva ASTM chiyero ichashandiswa kuyedza mhando yesilica, chinhu chakasvibirira chinoumba hwaro hwe "girinhi" matai.Makambani eTire uye vagadziri vesilica vanova ivo vekutanga vashandisi veiyo chiyero chitsva (D8016, Test Method yeSilica, Yakanaya, Yakanatswa - Sears Nhamba).Sekureva kwenhengo yeASTM Jorge Lacayo-Pineda, tekinoroji yesilika inovandudza mashandiro mukupikisa-kutenderedza matayi pasina kuderera mukuita braking.Izvi zvinotungamira kune nani mafuta ekufambisa, pamwe nekudzikiswa kwekabhoni dhaidhirosi kubuda mumotokari.Makambani eRubber, ivo vanonyanya kushandisa silica yakanaya, vanogona kuvandudza mataurirwo avo uye nekuona mhando yechigadzirwa nekuyedza kune iyo nyowani chiyero, anodaro.Iyo ASTM subcommittee yakagadzira D8016 inoronga kuita kutenderera robin kuyedzwa kwechirimo chinotevera kuti iongorore iyo chiyero chitsva.Rubber company labs, vagadziri vesilica uye masangano ezvidzidzo anokurudzirwa kujoina.Vatori vechikamu muchidzidzo vachapihwa sampuli dzekuongorora zvinoenderana nechiyero chitsva.
Precipitated silica
Bonding, anti adhesion, anti caking, coagulation, inodzorwa kusunungurwa, mutakuri, kuyerera rubatsiro, kuvandudza kudhinda maitiro, mechanic chiito, akakosha ekuwedzera e thermoplastic, kusimbisa, rheological control uye kuchena.Hydrophobic silica inobatwa nekugadziriswa kwepamusoro inonyungudika zviri nyore muoiri.Kana ichishandiswa sekusimbisa kuzadza murabha nemapurasitiki, iyo mechanic simba uye kubvarura kuramba kwezvigadzirwa zvayo inovandudzwa zvakanyanya.
Precipitated silica ine dzakasiyana siyana dzekushandisa, uye zvigadzirwa zvakasiyana zvine mashandisiro akasiyana.Seyakanaka inosimbisa mumiriri werabha yekugadzira, kuita kwayo kwekusimbisa ndeyechipiri chete kune kabhoni nhema, uye yakatonaka kupfuura kabhoni dema mushure mekupedzisira-kwakanaka uye kwakakodzera kwepamusoro kurapwa.Inonyanya kukodzera kugadzira zvichena, ruvara uye chiedza chemavara erubha zvigadzirwa.Inoshandiswa seyakakora kana thickener, kusanganisa ajenti yemafuta ekugadzira uye insulating pendi, dimming agent yepende, thixotropic agent weelectronic component packaging materials, precipitant of phosphor panguva yekuputira fluorescent screen, filler yeruvara kudhinda rabha ndiro uye mold kuburitsa ajenti yekukandira. .Kuwedzera muresin kunogona kuvandudza hunyoro-huchapupu uye kusungirira zvimiro zveresin.Kuzadza zvigadzirwa zvepurasitiki zvinogona kuwedzera skid kuramba uye kuramba mafuta.
