Kev txhais ntawm colloidal av nplaum . A av nplaum , xws li bentonite, uas, thaum tov nrog dej, tsim ib gelatinous zoo li kua.
Kuj paub, puas yog tag nrho cov av nplaum colloidal?
Av nplaum minerals thiab colloids yog cov xuab zeb ntau tshaj plaws; av nplaum minerals suav nrog feem ntau ntawm zoo tag nrho detrital mudrocks. Vim lawv cov feeb me me (feem ntau av nplaum yog <0. 004 mm (8 Ф-qhov siab tshaj ntawm av nplaum -size particles raws li Wentworth scale) feem ntau tsis yog av nplaum cov ntxhia.
Tsis tas li ntawd, colloidal txhais li cas? Hauv chemistry, a colloid yog ib qho sib xyaw uas ib yam khoom ntawm microscopically dispersed insoluble los yog soluble hais raug tshem tawm thoob plaws lwm yam khoom. Lub dispersed-theem hais muaj ib txoj kab uas hla ntawm kwv yees li 1 thiab 1000 nanometers.
Tsis tas li ntawd, koj ua li cas nrog av nplaum hauv dej zoo?
Ntxiv cov coagulant xws li txhuas sulfate rau koj dej zoo ntawm tus nqi ntawm 1/8 teaspoon rau txhua nkas loos ntawm dej yog tias lub lim micron ib leeg tsis tsim nyog tshem tawm av nplaum . Ferric chloride thiab lwm yam coagulants kuj muaj rau siv.
Cov av colloids yog dab tsi thiab vim li cas lawv tseem ceeb?
Cov av colloids yog cov active feem ntau ntawm cov av thiab nws txiav txim siab lub cev thiab tshuaj muaj zog ntawm lub av . Lawv yog tseem ceeb vim lawv qhov chaw nyiam av cov as-ham dissolved nyob rau hauv av , dej raws li zoo them cov ntxhia ions, los yog cations.

Lub zog ntawm hlau nplaum yog dab tsi?
Sib nqus quab yuam, attraction los yog repulsion uas tshwm sim ntawm hluav taws xob nqi hais vim lawv cov lus tsa suab. Nws yog lub hauv paus quab yuam lub luag haujlwm rau cov teebmeem xws li kev txiav txim ntawm lub tshuab hluav taws xob thiab kev nyiam ntawm cov hlau nplaum rau hlau
Dab tsi yog cov hlau nplaum uas ua los ntawm qhov kev npaj ntawm electrons yog dab tsi?
Electrons yog teem rau hauv plhaub thiab orbitals nyob rau hauv ib tug atom. Yog hais tias lawv sau lub orbitals kom muaj ntau spin taw tes rau hauv qab (los yog vice versa), txhua atom yuav ua zoo li ib tug me me hlau nplaum. Thaum ib daim ntawm cov hlau tsis muaj hlau nplaum (lossis lwm yam khoom siv ferromagnetic) raug rau sab nraud magnetic teb, ob yam tshwm sim
Cov av nplaum yog dab tsi?
Cov av nplaum nyoos yog cov av nplaum dawb huv, tsis muaj pob zeb, sticks lossis lwm yam kab mob. Peb cov qauv kev sim tau muab Sheffield Clay nrog lwm cov av nplaum ntau dua, ua rau muaj qhov sib txawv, zoo ntawm cov av nplaum lub cev tsis sib npaug hauv Northeast. Cov av nplaum ntuj yog ces muab tso rau hauv lub hnub kom pib ziab
Cov hlau nplaum ruaj khov puas poob hlau nplaum?
Yog lawm, nws muaj peev xwm ua tau rau cov hlau nplaum ruaj khov kom poob nws cov hlau nplaum. Muaj peb txoj hauv kev rau qhov no tshwm sim: 2) Ntawm qhov demagnetizing magnetic teb: cov hlau nplaum tas mus li nthuav tawm cov yam ntxwv hu ua coercivity, uas yog lub peev xwm ntawm cov khoom siv los tiv thaiv demagnetized los ntawm kev siv magnetic teb
Dab tsi yog cov khoom tseem ceeb ntawm av nplaum?
Cov ntxhia hauv av yog hydrous aluminium phyllosilicates, qee zaum muaj ntau yam ntawm cov hlau, magnesium, alkali hlau, alkaline ntiaj teb, thiab lwm yam cations pom ntawm lossis ze ntawm qee qhov chaw ntawm lub ntiaj teb. Av nplaum minerals tsim nyob rau hauv lub xub ntiag ntawm dej thiab muaj ib tug tseem ceeb rau lub neej, thiab ntau txoj kev xav ntawm abiogenesis koom nrog lawv
