Izici zezinto ezibonakalayo ze-silica gel, ubuchwepheshe bokucubungula kanye nokusetshenziswa

I-silica gel impahla inezici zokusebenza okuphezulu kwe-adsorption, ukuzinza okuhle kokushisa, ukuqina kwamakhemikhali, amandla aphezulu emishini nokunye, futhi isetshenziswa kabanzi ekwakhiweni komkhiqizo. Futhi impahla yaguqulwa yaba ijeli ye-silica ekhethekile ukuze ivumelane nezidingo zokusebenza zemikhiqizo ehlukene, njengama-ion akhanyayo, ama-negative, ukushintsha kombala nezinye izici.

Isingeniso sejeli ye-silica

Ijeli ye-silica iwuhlobo lwezinto ezisebenza kakhulu ze-adsorption, iyingxenye ye-amorphous substance, equkethe i-polysiloxane, uwoyela we-silicone, i-silica emnyama (i-silica), i-coupling agent kanye ne-filler, njll., ingxenye eyinhloko i-silica. Ayincibiliki emanzini nanoma iyiphi i-solvent, engeyona enobuthi futhi ayinambitheki, izinzile kumakhemikhali, ngaphezu kwe-alkali eqinile, i-hydrofluoric acid ayiphenduli nganoma iyiphi into. Izinhlobo ezahlukahlukene zejeli ye-silica zakha izakhiwo ezihlukene ze-micropore ngenxa yezindlela zazo ezihlukene zokukhiqiza. Ukwakheka kwamakhemikhali kanye nesakhiwo somzimba sejeli ye-silica inquma ukuthi inezici zezinye izinto eziningi ezifanayo okunzima ukuzishintsha: ukusebenza okuphezulu kwe-adsorption, ukuqina okuhle kokushisa, izakhiwo zamakhemikhali ezizinzile, namandla aphezulu emishini.

Ukuhlukaniswa kwejeli ye-silica

I-Silicone ingahlukaniswa ngokuya ngezici ezahlukahlukene:

Ngokusho ukwakheka zingahlukaniswa zibe: ingxenye eyodwa kanye izingxenye ezimbili silica gel.
Ngokusho izinga lokushisa vulcanization ingahlukaniswa: izinga lokushisa eliphezulu vulcanization futhi ekamelweni lokushisa vulcanization abicah.
Ngokusho kokuma komkhiqizo kungahlukaniswa: ijeli ye-silica ewuketshezi futhi eqinile.
Ngokusho kokusabela kwe-vulcanization kungahlukaniswa: uhlobo lokusabela kwe-condensation, uhlobo lwe-platinum kwalokho lokusabela kanye nohlobo lokuhlanganiswa kwe-peroxide.
Ngokusho kwesakhiwo esikhulu seketango singahlukaniswa sibe: ijeli ye-silica ehlanzekile kanye nejeli ye-silica eguquliwe.
Ngokwezici zomkhiqizo zingahlukaniswa zibe: uhlobo lokumelana nokushisa okuphezulu nokuphansi, uhlobo lwe-anti-static, ukumelana nowoyela kanye ne-solvent, uhlobo lwe-conductive, uhlobo lwesipontshi segwebu, uhlobo lokumelana nezinyembezi eziphakeme, uhlobo lokuvikela umlilo olubushelelezi, uhlobo oluphansi lokucindezelwa komlilo. .
