Dispers sistemalar. Kolloid dispers sistemalarni olinishi va hossalari. Kolloid dispers sistemalarning barqarorligi

Dispers sistemalarning turlanishi

• Faza va muhit agregat holati bo`yicha:
• Gaz-gazda - eritma
• Gaz-suyuqlikda - ko`pik
• Gaz-qattiq moddada - qattiq ko`pik (pemza, g`isht)
• Suyuqlik-gazda - aerozol (tuman)
• Suyuqlik-syuqlikda - emulsiya
• Suyuqlik-qattiq moddada -gel
• Qattiq modda-gazda - aerozol (chang, kukun)
• Qattiq modda-syuqlikda - suspenziya, zol
• Qattiq modda-qattiq moddada - qotishma

Dispers sistemalarning turlanishi

• Dispers faza va dispers muhit ta`sirlashishi bo`yicha:
• Liofil - oqsil, krahmal, agar-agar
• Liofob - metallar (oltin, kumush), temir sulfid, kumush hlorid zollari
• Dispers muhit (erituvchi) tabiati bo`yicha:
• Gidrozollar (suv), benzozollar (benzol),
• alkozollar (spirt), eterozollar (efir)

Kolloid dispers sistemalarning olinish usullari

• Dispersion usullar:
• Mehanik (kolloid tegirmonda, havonchada yirik zarrachalarni kolloid zarracha kattaligigacha maydalash) usuli
• Ultratovush yordamida yirik zarrachalarni kolloid zarracha kattaligigacha maydalashusuli
• Peptizatsiyalash (kimyoviy usul) - yangi tayorlangan cho`kmani elektrolit (peptizator) yordamida geldan yana zolga o`tkazish usuli
