Silicon dioxide Siv nyob rau hauv Pharmaceutical Industry

Silicon dioxide, tseem hu ua colloidal silica lossis nplua silica, yog siv dav hauv kev lag luam tshuaj. Nws qhov me me me me thiab qhov chaw siab saum npoo ua rau nws zoo tagnrho rau kev txhim kho cov dej ntws ntawm cov hmoov qhuav, xws li hauv cov ntsiav tshuaj compression. Nws kuj tuaj yeem siv los ua kom ruaj khov emulsions, ua thixotropic thickener thiab tshem tawm tus neeg sawv cev hauv cov gels thiab cov txheej txheem ib nrab.

Thaum ua ke nrog lwm cov khoom siv nrog cov ntsuas zoo sib xws, silicon dioxide tuaj yeem tsim cov gels pob tshab. Qhov nce hauv viscosity nyob ntawm qhov polarity ntawm cov kua, nrog cov polar solvents xav tau ntau dua ntawm silica dua li cov kuab tshuaj tsis yog polar. Viscosity tsis cuam tshuam los ntawm qhov kub thiab txias, tab sis kev hloov pauv hauv pH tuaj yeem cuam tshuam rau nws.

Nyob rau hauv cov kaus poom aerosols, silicon dioxide yog siv los txhim kho kev ncua ntawm cov khoom thiab txo cov nozzle blockages. Nws kuj tseem siv tau los ua cov tshuaj disintegrant hauv cov ntsiav tshuaj, ua kua adsorbing dispersant hauv cov hmoov, thiab ua kom cov viscosity ntawm lipophilic suppositories los tiv thaiv sedimentation thiab txo qis tso tawm. Kev nyab xeeb colloid silicon dioxide yog dav siv hauv qhov ncauj thiab qee cov tshuaj pleev ib ce thiab feem ntau suav tias yog cov tshuaj tsis muaj tshuaj lom thiab tsis ua rau khaus.

Hauv kev xaus, silicon dioxide yog cov khoom muaj ntau yam hauv kev lag luam kws tshuaj nrog ntau yam khoom tsim nyog, suav nrog cov dej ntws zoo, ruaj khov emulsions, thixotropic zog, tshem tawm cov khoom, thiab tswj kev tso tawm ntawm cov tshuaj. Tag nrho cov yam ntxwv no ua rau muaj kev txhim kho ntawm kev nyab xeeb thiab kev siv tshuaj zoo.
