Makhalidwe oyimitsidwa
Zitsanzo za kuyimitsidwa

Mu chemistry, a kuyimitsidwa Ndi mtundu wosakanikirana wosakanikirana wopangidwa ndi chinthu chimodzi kapena zingapo zolimba zomwe zimamwazika mu chinthu chamadzimadzi kapena chamadzimadzi. Mu kuyimitsa, gawo lolimba (lomwazika) silimasungunuka mumayendedwe amadzi (gawo lobalalitsa). Mwachitsanzo: madzi a lalanje, popeza zamkati zimayandama ndipo siziphatikizidwa ndi madzi amadzimadzi, opaka ufa.

Kuyimitsidwa ndikosakanikirana kwakukulu chifukwa ndizotheka kusiyanitsa tinthu timene timapanga. Amakhala osakanikirana osakhazikika, chifukwa, chifukwa cha kukula kwake, tinthu tating'onoting'ono tomwe timayimitsidwa timatha kukhazikika mosavuta pomwe chisakanizocho chikupuma.

Itha kukutumikirani: Zosakaniza zolimba ndi zakumwa

Makhalidwe oyimitsidwa

Ndiosakanikirana mosavuta chifukwa nthawi zambiri amakhala opaque.
Ngakhale zambiri zimapangidwa ndi zinthu zolimba komanso zamadzimadzi (kuyimitsidwa kwamakina), imathanso kukhala yamadzi + yamadzi komanso yolimba kapena yamadzi. Chitsanzo cha chinthu cholimba chomwazika mu mpweya ndi aerosol.
M'mafakitale osiyanasiyana, zinthu monga opanga mafunde ndi ma thickeners amagwiritsidwa ntchito poletsa zolimba zosakanikirana kuti zitheke.
Ambiri amafunika kusakanizidwa kapena kugwedezeka kuti abwerere kuimidwe awo oimitsidwa.
Amasiyana ndi mayankho chifukwa ma particles olimba ndi akulu, ndipo m'mayankho ake olimba amasungunuka m'madzi, ndikupangitsa kuti pakhale chisakanizo chimodzi.
Amasiyana ndi ma colloids, chifukwa mwa iwo ma particles olimba ndiabwino (m'mimba mwake pakati pa 10⁻⁹ ndi 10⁻⁵ nanometer).
Zinthu zomwe zimapanga izi zitha kusiyanitsidwa ndi njira zakuthupi monga kusefera, centrifugation ndikuchotsa.
