Tsvagiridzo pamusoro pekushandiswa kwe silica gel desiccant

Mukugadzirwa uye hupenyu, silica gel inogona kushandiswa kuomesa N2, mhepo, hydrogen, gasi rechisikigo [1] zvichingodaro. Zvichienderana neacid nealkali, desiccant inogona kukamurwa kuita: acid desiccant, alkaline desiccant uye neutral desiccant [2]. Silica gel inoita kunge neutral dryer inoita seinoomesa NH3, HCl, SO2, nezvimwewo. Zvisinei, kubva pamaonero ekutanga, silica gel inoumbwa ne three-dimensional intermolecular dehydration yema orthosilicic acid molecules, muviri mukuru iSiO2, uye pamusoro payo pane hydroxyl groups (ona Mufananidzo 1). Chikonzero nei silica gel ichigona kunwisa mvura ndechekuti boka resilicon hydroxyl riri pamusoro pe silica gel rinogona kuumba intermolecular hydrogen bonds nemamorekuru emvura, saka rinogona kunwisa mvura uye nokudaro richiita basa rekuomesa. Silica gel inochinja ruvara ine cobalt ions, uye mushure mekunge mvura ye adsorption yasvika pakuzara, cobalt ions mu silica gel inochinja ruvara inova hydrated cobalt ions, zvekuti blue silica gel inova pink. Mushure mekudziya gel repingi resilica pa200℃ kwenguva yakati, chisungo chehydrogen pakati pegel resilica nemamorekuru emvura chinotyoka, uye gel resilica rakashanduka ruvara rinoshanduka kuita bhuruu zvakare, kuitira kuti dhizaini yechimiro chesilicic acid negel resilica zvigone kushandiswazve sezvakaratidzwa paMufananidzo 1. Saka, sezvo pamusoro pegel resilica gel paine hydroxyl groups, pamusoro pegel resilica gel zvinogonawo kugadzira intermolecular hydrogen bonds neNH3 neHCl, nezvimwewo, uye pangave pasina nzira yekushanda se desiccant yeNH3 neHCl, uye hapana mushumo wakakodzera mumabhuku aripo. Saka mhedzisiro yacho yaive ipi? Nyaya iyi yakaita tsvakiridzo inotevera yekuyedza.
