I-Silicone ye-Inorganic
I-silicone ye-inorganic iyinto esebenza kakhulu ye-adsorbent, evame ukusabela nge-sodium sulfate ne-sulfuric acid. Ijeli ye-silica iyinto e-amorphous ene-chemical molecular formula mSiO2.nH2O. Ayincibiliki emanzini nanoma iyiphi i-solvent, ayinabo ubuthi futhi ayinaphunga, inezinto zamakhemikhali ezizinzile, futhi ayisebenzi nganoma iyiphi into ngaphandle kwe-alkali eqinile ne-hydrofluoric acid.
Izinhlobo ezahlukene zejeli ye-silicone zakha ukwakheka okuhlukile kwe-microporous ngenxa yezindlela zazo ezihlukene zokukhiqiza. Ukwakheka kwamakhemikhali kanye nokwakheka komzimba kwejeli ye-silica kunquma ezinye izinto eziningi ezifanayo: ukusebenza okuphezulu kwe-adsorption, ukuzinza okuhle kokushisa, izakhiwo zamakhemikhali ezizinzile, amandla aphezulu emishini, i-desiccant yasekhaya, isilawuli somswakama, isiqedaphunga, njll. ukusetshenziswa kwezimboni njengesikhiphi se-hydrocarbon, isithwali se-catalyst, i-pressure adsorbent, i-ejenti enhle yokuhlanza ukuhlukaniswa kwamakhemikhali, i-stabilizer kabhiya, i-thickener kapende, i-ejenti yokungqubuzana kwe-toothpaste, inhibitor elula, njll.
Ngokobukhulu bomgodi wokuvula, ijeli ye-silica ihlukaniswe yaba ijeli ye-silica yembobo enkulu, ijeli ye-silica yembobo eqinile, ijeli yohlobo B ye-silica kanye nejeli ye-silica yembobo. Ijeli ye-silica eqinile inenani eliphakeme lokukhanga elinomswakama ophakeme kakhulu, kuyilapho ijeli ye-silica ecwebezelayo idonsa ama-oda aphezulu kunejeli ye-silica emahhadla enomswakama ophansi kakhulu, kuyilapho uthayipha ijeli ye-silica engu-B, ngoba ukwakheka kwembotshana kuphakathi kwezimbobo ezimahhadla nezicolekileyo, kanye nenani le-adsorption yalo liphakathi kwezimbobo ezimahhadla nezicolekileyo.
Ngokusetshenziswa kwayo, i-silicone ye-inorganic ingabuye ihlukaniswe ibe i-silicone kabhiya, i-silicone ye-adsorbent eshintsha ukucindezela, i-silicone yezokwelapha, i-silicone yokushintsha umbala, i-silicone desiccant, i-agent yokuvula i-silicone, i-silicone yokuxubha amazinyo, njll.
I-silica Gel enezimbobo ezinhle
Ijeli ye-silica ecwebezelayo ayinambala noma iphuzi kancane ebonisa ngale, eyaziwa nangokuthi ijeli.
Isicelo: ifanele indawo eyomile, umswakama nokuvikela ukugqwala. Ingavimbela amathuluzi, amathuluzi, izikhali, izinhlamvu, okokusebenza kukagesi, izidakamizwa, ukudla, izindwangu nezinye izinto zokupakisha ukuthi zingabi manzi, futhi zingasetshenziswa njengezithwali ze-catalyst kanye nokuphelelwa amanzi emzimbeni kanye nokucwengisiswa kwezinhlanganisela eziphilayo. Ngenxa yobuningi bokuqoqwana okuphezulu kanye nomswakama ophansi, ingasetshenziswa njenge-desiccant ukulawula umswakama womoya. Ibuye isetshenziswe kabanzi endleleni yolwandle, ngoba izimpahla zivame ukulinyazwa umswakama, futhi umkhiqizo ungaba ngokuphumelelayo futhi ube nomswakama, ukuze ikhwalithi yezimpahla iqinisekiswe. I-silicone ene-fine-porous iphinde isetshenziselwe ukususa umswakama phakathi kwezingqimba ezimbili zamaphaneli efasitelana avala uphawu futhi ingagcina ukugqama kwezingqimba ezimbili zengilazi.
B Uhlobo lwe-Silica Gel
Uhlobo B Ijeli ye-Silica iyi-milky ebonisa ngale noma i-translucent eyindilinga noma izinhlayiya zebhulokhi.
Isicelo: sisetshenziswa kakhulu njengesilawuli somswakama womoya, i-catalyst nesithwali, impahla ye-cushion yesilwane, nanjengempahla eluhlaza yemikhiqizo yamakhemikhali emihle njenge-silica chromatography.
I-Gel ye-Hole ye-Silica Gel
Ijeli ye-silica enezimbobo ezimahhadla, eyaziwa nangokuthi i-silica yohlobo lwe-C, iwuhlobo lwejeli ye-silica, iyinto esebenza kakhulu ye-adsorbent, i-amorphous material, i-chemical formula yayo i-mSiO2 · nH2O. Ayincibiliki emanzini nanoma iyiphi i-solvent, ayinabo ubuthi futhi ayinaphunga, inezinto zamakhemikhali ezizinzile, futhi ayisebenzi nganoma iyiphi into ngaphandle kwe-alkali eqinile ne-hydrofluoric acid. Ukwakheka kwamakhemikhali kanye nesakhiwo somzimba sejeli ye-silica enezimbobo ezimahhadlahhadla kunquma ukuthi inezinye izinto eziningi ezifanayo okunzima ukuzishintsha: ukusebenza okuphezulu kwe-adsorption, ukuqina okuhle kokushisa, izakhiwo zamakhemikhali ezizinzile namandla aphezulu emishini.
Isicelo: ijeli ye-silica e-coarse porous imhlophe, i-block, i-spherical and micro spherical products.coarse hole spherical silica gel isetshenziselwa ikakhulukazi ukuhlanza igesi intuthwane, i-desiccant kanye namafutha okuvikela; ijeli ye-silica eyinqwaba ye-coarse-hole isetshenziselwa ikakhulukazi isithwali se-catalyst, i-desiccant, igesi kanye nezintuthwane zokuhlanza uketshezi, njll.
Ibonisa i-silica Gel
Ukubonisa i-Silica Gel inemibala emi-2. Okuluhlaza okwesibhakabhaka nowolintshi.
Isicelo: Uma uyisebenzisa njenge-desiccant, iluhlaza okwesibhakabhaka / i-orange ngaphambi kokumuncwa kwamanzi, futhi ngemva kokuphenduka okubomvu / okuluhlaza ngemva kokumuncwa kwamanzi, okungabonakala ekushintsheni kombala, nokuthi ingabe ukwelashwa kokuvuselela kuyadingeka. I-Silica Gel nayo isetshenziswa kabanzi ekubuyiseleni umhwamuko, ukucwenga uwoyela kanye nokulungiswa kwe-catalyst. I-silica Gel ingasetshenziswa futhi ukwenza igobolondo leselula, enocansi oluphakeme kakhulu lokulwa nokuwa.
I-Silica Alumina Gel
Izakhiwo zamakhemikhali ezizinzile, ezingashi futhi ezingancibiliki kunoma iyiphi i-solvent. Ijeli ye-aluminium ye-silica enezimbobo ezinhle kanye nejeli ye-silica enezimbobo ezinhle iqhathaniswa nevolumu ye-adsorption yomswakama ophansi (efana no-10% we-RH =, RH=20%), kodwa ivolumu yokukhangisa komswakama ophezulu (njenge-RH=80%, RH=90%) I-6-10% ephakeme kunejeli ye-silica enezimbobo ezinhle, sebenzisa: ukuzinza okushisayo kuphakeme kunejeli ye-silica enezimbobo ezinhle (200 ℃), ilungele kakhulu i-adsorption yezinga lokushisa kanye ne-ejenti yokuhlukanisa.
