Izinhlayiya ze-Colloidal, okungekho lula ukuzixazulula ngokwemvelo emanzini amdaka.

Kungani izinhlayiya ze-colloidal emanzini amdaka kungabi lula ukuzixazulula ngokwemvelo?


Emanzini angcolile, izinto eziningi ezinamandla adonsela phansi angaphezu kwe-1 zingasuswa ngokudilizwa kwendalo, i-centrifugation kanye nezinye izindlela. Isibonelo, ama-solids amisiwe, izinhlayiya ezinkulu, nezinsimbi ezimisiwe okulula ukuzixazulula.


Kodwa-ke, kunzima ukuthi izinhlayiya zemvelo zixazulule ngokwemvelo uma izinhlayiya ezilengisiwe ezinamandla athile adonsela phansi okungaphansi koku-1 zincane noma zingabonakali ngamehlo enyama.


Such as colloidal particles are extremely small particles, which are very stable in water. Its settlement speed is extremely slow, and it takes 200 years to settle 1m.


Kunezizathu ezimbili eziyinhloko zokuxazululwa kancane:


(1) Ngokuvamile, izinhlayiya ze-colloidal zonke zinecala elibi. Ngoba baxoshwa abobulili obufanayo, bangavimbela izinhlayiya ze-colloidal ukuthi zixhumane futhi aziboshelwe komunye, ngakho-ke zimisiwe emanzini.


(2) Kukhona futhi ungqimba lwama-molecule ebusweni bezinhlayiya ze-colloidal azungeze ngokuqinile. Lolu ungqimba lwe-hydration luphinde luphazamise futhi luhlukanise ukuxhumana phakathi kwezinhlayiya ze-colloidal, ukuze lungakwazi ukunamathela komunye nomunye, bese lumiswa emanzini.
