Silica gel zvinhu maitiro, kugadzirisa tekinoroji uye kushandisa
Silica gel zvinhu zvine hunhu hwepamusoro adsorption kuita, yakanaka kugadzikana kwekupisa, kugadzikana kwekemikari, kusimba kwemagetsi uye zvichingodaro, uye inoshandiswa zvakanyanya mukugadzirwa kwechigadzirwa. Uye izvo zvinhu zvakagadziridzwa kuita yakakosha silica gel kuti ienderane nezvinodiwa zvinoshanda zvezvigadzirwa zvakasiyana, senge zvinopenya, zvisina kunaka ion, discoloration uye humwe hunhu.
Nhanganyaya kune silica gel
Silica gel imhando yeanoshanda adsorption zvinhu, ndeye amorphous substance, iyo ine polysiloxane, silicone mafuta, silica dema (silica), coupling agent uye filler, nezvimwewo, chikamu chikuru isilika. Insoluble mumvura uye chero inonyungudutsa, isiri-chepfu uye isinganakidze, yakagadzikana yemakemikari, kuwedzera kune yakasimba alkali, hydrofluoric acid haina kuita chero chinhu. Mhando dzakasiyana-siyana dzesilica gel dzinogadzira akasiyana micropore zvimiro nekuda kwemaitiro avo akasiyana ekugadzira. Kuumbwa kwemakemikari uye chimiro chemuviri chesilica gel chinotarisa kuti ine hunhu hwezvimwe zvinhu zvakawanda zvakafanana izvo zvakaoma kutsiva: yakakwira adsorption performance, yakanaka thermal kugadzikana, yakagadzikana makemikari zvimiro, uye yakakwirira mechanical simba.
Kurongeka kwesilica gel
Silicone inogona kuiswa zvichienderana nemhando dzakasiyana siyana:
Zvinoenderana nekuumbwa kunogona kukamurwa kuita: chimwe chikamu uye maviri chikamu silica gel.
Maererano tembiricha vulcanization inogona kukamurwa kuva: yakakwirira tembiricha vulcanization uye kamuri tembiricha vulcanization silicone.
Zvinoenderana nechimiro chechigadzirwa chinogona kukamurwa kuita: mvura uye yakasimba silica gel.
Zvinoenderana neiyo vulcanization reaction inogona kukamurwa kuita: condensation reaction type, platinamu yekuwedzera maitiro emhando uye peroxide yekubatanidza mhando.
Zvinoenderana neiyo huru cheni chimiro chinogona kukamurwa kuita: pure silica gel uye yakagadziridzwa silica gel.
Zvinoenderana nehunhu hwechigadzirwa hunogona kukamurwa kuita: yakakwira uye yakaderera tembiricha yemhando yekudzivirira, anti-static mhando, mafuta uye solvent kuramba, conductive mhando, furo sponge mhando, yakakwira simba rekubvarura rudzi, murazvo unodzoreredza moto wekudzivirira mhando, yakaderera compression deformation mhando. .
