I-Silica Gel ye-Macroporous

Izici
Ijeli ye-silika ye-macroporous iwuhlobo olukhethekile lwejeli ye-silica.Njengamanye ama-silica gels, iyimpahla ye-adsorption esebenza kakhulu.Kuyinto e-amorphous futhi ifomula yayo yamakhemikhali ithi mSiO2 · nH2O.Ijeli ye-silika ye-macroporous ayincibiliki emanzini nanoma iyiphi i-solvent, ayinabuthi, ayinambitheki, izinzile kumakhemikhali, futhi ayisebenzi nanoma yiziphi izinto ngaphandle kwe-alkali eqinile ne-hydrofluoric acid.Njengoba indlela yokukhiqiza yejeli ye-silika ye-macroporous ihlukile kuneyamanye ama-silica gels, kwakhiwa izakhiwo ezihlukene ezincane.Umehluko omkhulu phakathi kwayo namanye ama-silica gels ukuthi ivolumu yembotshana inkulu, okungukuthi, umthamo we-adsorption mkhulu, futhi amandla adonsela phansi ngobuningi alula kakhulu.


Imininingwane Yomkhiqizo

Omaka bomkhiqizo

Igama lomkhiqizo: Ijeli ye-silika ye-macroporous
into: Ukucaciswa:

Isicelo:i-petrochemical, amathuluzi kagesi, izinto zasendlini, amalabhorethri aphathekayo/amakhemikhali, i-biopharmaceuticals, izingubo zokugqoka, izicathulo nezigqoko, izikhwama zezandla nezimboni zokudla.
Lo mkhiqizo usetshenziswa kabanzi ku-stabilizer kabhiya, i-catalyst kanye ne-catalyst catalyst, i-macromolecule protein adsorption emikhiqizweni yokuvutshelwa, ukuhlanzwa kanye nokuhlanzwa kwezinto eziphilayo ezisebenzayo, ukuhlanzwa kwamanzi kanye nokubuyiswa kwezinsimbi eziyigugu, imithi ye-herbal yaseShayina nezidakamizwa zokwenziwa, ukuhlukaniswa nokuhlanzwa kwezingxenye ezisebenzayo. , okokusebenza okunamathelayo okungamelana namanzi okuyimpahla yokuhlukanisa komoya.

Ukunaka: Umkhiqizo awukwazi ukuvezwa emoyeni ovulekile futhi kufanele ugcinwe endaweni eyomile nephakheji elifaka umoya.
Iphakheji:Isikhwama esilukiweyo / izigubhu zamabhokisi noma izigubhu zensimbi
