Ruzivo rweChigadzirwa

Matagi eChigadzirwa

Nhanganyaya:
Silica (makemikari fomura: SiO2) iacidic oxide, uye hydrate inoenderana nayo i silicic acid (H2SiO3). Silica ndiyo chinhu chakakosha zvikuru che silicon. Silica yechisikigo iripo panyika inokwana 12% yehukuru hweganda repasi. Kuvapo kwayo kwakasimba uye kusina morphous. Inonzi silica pamwe chete.

Silica yemhando yechikafu inonyanya kushandiswa semushonga wekudzivirira kubikwa kwemukaka muupfu hwezai, hupfu hwemukaka, hupfu hwekoko, bhota rekoko, hupfu hweshuga, hupfu hwemafuta, kofi inokurumidza, soup yehupfu uye poda.

Zvidimbu zveupfu hwechikafu zvinowanzobatana pamwe chete uye kuungana nekuda kwekuchinja kwetembiricha, hunyoro hwakawanda hwenzvimbo, kana kumanikidzwa pakati pemapakeji, izvo zvinokanganisa kunaka kwechigadzirwa uye hupenyu hwekuchengetera. Silicon dioxide ine simba rekudzivirira kubatwa kwechikafu, kunyanya nekuparadzanisa zvidimbu zvega zvega zvichibva pakuvharwa kwezvidimbu zveupfu hwechikafu, kuchengetedza upfu huri mumamiriro ezvinhu ekuti hunofanira kuyerera zvakasununguka uye huchibudirira mukudzivirira kubatwa kwechikafu.

Pamusoro pezvo, silica yakavharirwa kunze kweupfu inogayiwa uye inonyudzwa nehunyoro hwemagasi akaipoteredza kuburikidza nemaburi madiki, zvichidzivirira chikafu kuti chisanyorove uye chisaungane panguva yekuchengetwa.

Danho rekuchengetedza:

Silicon dioxide (SiO2) imushonga wepasi rose uye unotenderwa neFDA unodzivirira kubikwa kwechikafu. Silicon dioxide inoshandiswa muzvigadziro zvekudya ihupfu huchena hwakaita semukaka hwesilicon dioxide yakagadzirwa nenzira yakagadzirwa nemaoko.

Silica yakagadzirwa ine hunhu hwenzvimbo yakakura, porosity yakakwira, adsorption yakasimba, hunhu hwakasimba hwemuviri, haina chepfu, haina hwema, uye haina mhedzisiro mumuviri wemunhu mushure mekudyiwa.

Cherechedza:Zvikafu zvinojairika zvinoshandisa silica zvinosanganisira zvinonhuwira zveupfu, upfu hwemafuta emuriwo, chikafu chekupfapfaidza, zvinhu zvakavharirwa muzvikamu zvidiki, zvinonhuhwirira zveupfu, nezvimwewo, nehuwandu hwekushandisa hunosvika 0.25~2%.
