Isihluzo seemolekyuli

I-molecular sieve yi-adsorbent eqinileyo ekwazi ukwahlula iimolekyuli ezinobukhulu obahlukeneyo. I-SiO2, i-Al203 njenge-crystalline aluminium silicate kunye necandelo eliphambili. Kukho imingxunya emininzi yobukhulu obuthile kwikristale yayo, kwaye kukho imingxunya emininzi yobukhulu obufanayo phakathi kwayo. Iyakwazi ukubhengeza iimolekyuli ezincinci kunedayamitha yepore ukuya ngaphakathi komngxuma, kwaye ingabandakanyi iimolekyuli ezinkulu kunendawo yokuvula ngaphandle, idlala indima yesihluzo.

I-molecular sieve inamandla okufunxa ukufuma, kwaye phantse zonke izinyibilikisi zingasetyenziselwa ukuwomisa, ngoko ke isetyenziswa kakhulu elabhoratri nakwishishini. Indlela ye-molecular sieve adsorption yindlela yokuphelisa amanzi kunye nokusetyenziswa kwamandla aphantsi kunye nokusebenza kakuhle okuphezulu, inkqubo ilula, ifaneleka ngakumbi ukuphelelwa ngamanzi emzimbeni kunye negesi, ukusetyenziswa kobungakanani be-molecular sieve aperture ekhethiweyo yokungena kwamanzi, ukuze ukuzuza ukwahlukana.

Uzinzo lwe-thermal ye-molecular sieve lulungile, olunokumelana nobushushu obufutshane obuphezulu be-600C ~ 700C, kwaye ukushisa kokuvuselela akufanele kudlule i-600C, kungenjalo kuchaphazele umsebenzi we-molecular sieve, kwaye inokukhutshwa (akukho ukuhlaziywa kwe-thermal). I-molecular sieve ayinyibiliki emanzini, kodwa inyibilika kwi-acids eqinile kunye ne-alkali, ngoko ingasetyenziselwa phakathi kwe-pH5 ~ 11. I-molecular sieve ilula ukufunxa amanzi, kufuneka igcinwe itywiniwe, ukusetyenziswa kufuneka kuhlolwe ukuba umxholo wamanzi udlula umgangatho, ukugcinwa kwexesha elide lokufunxa ukufuma, kufuneka kusetyenziswe emva kokusetyenziswa, ukusebenza kwayo kungatshintshi. I-molecular sieve ineempawu zesantya se-adsorption esikhawulezayo, amaxesha amaninzi okuhlaziya, ukutyumza okuphezulu kunye nokunganyangeki, ukuchasana nokungcoliseka okunamandla, ukusebenza kakuhle kokusetyenziswa, ubomi obude benkonzo, njl.
