Ukusetyenziswa kwenkqubo yokucoca isihluzo se-molecular kwiyunithi yokwahlula umoya
Umoya ocinezelwe yi-air compressor usebenzisa i-alumina esebenzayo evuselelayo kunye nesihluzo se-molecular ukususa amanzi, i-carbon dioxide, i-acetylene, njl. Njenge-adsorbent, isihluzo se-molecular sinokufunxa ezinye iigesi ezininzi, kwaye sinotyekelo olucacileyo kwinkqubo yokufunxa. Okukhona inkulu i-polarity ye-m...Funda ngokugqithisileyo -
Ngaba i-zeolite yendalo inetyhefu? Ngaba iyatyiwa?
Ngaba i-zeolite yendalo inetyhefu? Ngaba iyatyiwa? Ngo-1986, isiganeko saseChernobyl sabangela ukuba yonke idolophu entle itshatyalaliswe ngobusuku obunye, kodwa ngethamsanqa, abasebenzi basinda, kwaye ngabantu abathile kuphela abenzakeleyo nabakhubazekileyo ngenxa yengozi. Yayikwayingozi enkulu eyabangela...Funda ngokugqithisileyo -
Iimpawu eziphambili zeenkampani ezininzi ezidumileyo kwihlabathi liphela ze-catalysts
Ngenxa yokuphuculwa okuqhubekayo kwamandla okucocwa kwehlabathi, imigangatho yemveliso yeoyile eqinayo, kunye nokwanda okuqhubekayo kwemfuno yezinto ezikrwada zamakhemikhali, ukusetyenziswa kwezinto eziphuculayo kuye kwaba sendleleni yokukhula okuqhubekayo. Phakathi kwazo, ukukhula okukhawulezayo kukwi...Funda ngokugqithisileyo -
Tyhila abavelisi be-10 abadumileyo kwihlabathi liphela bokucoca ioyile
Ngenxa yokuphuculwa okuqhubekayo kwamandla okucocwa kwehlabathi, imigangatho yemveliso yeoyile eqinayo, kunye nokwanda okuqhubekayo kwemfuno yezinto ezikrwada zamakhemikhali, ukusetyenziswa kwezinto eziphucula ukucocwa kuye kwaba sendleleni yokukhula okuqhubekayo.

Isihluzo semolekyuli sisixhobo esineembobo (imingxunya emincinci kakhulu) ezinobukhulu obufanayo
Isihluzo semolekyuli sisixhobo esineembobo (imingxunya emincinci kakhulu) ezinobukhulu obufanayo. Ezi dayamitha zembobo zifana ngobukhulu neemolekyuli ezincinci, ngoko ke iimolekyuli ezinkulu azinakungena okanye zifunxwe, ngelixa iimolekyuli ezincinci zisenako. Njengoko umxube weemolekyuli uhamba nge...Funda ngokugqithisileyo -
Yintoni iSilicone?
Ijeli yeSilica ngumxube wamanzi kunye ne-silica (iminerali efumaneka rhoqo kwisanti, kwi-quartz, kwi-granite nakwezinye iiminerali) eyenza amasuntswana amancinci xa ixutyiwe. Ijeli yeSilica yi-desiccant enomphezulu ogcina umphunga wamanzi endaweni yokuwufunxa ngokupheleleyo. I-silicone bead nganye...Funda ngokugqithisileyo -
Ii-Sieves zeMolekyuli
IZINTO EZINOKUGCINA IIMBINERAL, II-FILTER AGENTS, KUNYE NEE-DRYING ARAGENS Ii-molecular seeves zii-crystalline metal aluminosilicate ezine-threedimensional interconnecting network ye-silica kunye ne-alumina tetrahedra. Amanzi endalo okufunxa amanzi asuswa kule netwekhi ngokufudumeza ukuze kuveliswe imingxunya efanayo evumela...Funda ngokugqithisileyo -
Zisebenza njani iiMolecular Sieves?
Isihluzo semolekyuli sisixhobo esineembobo ezinemingxuma emincinci kakhulu, enobukhulu obufanayo. Sisebenza njengesihluzo sasekhitshini, ngaphandle kwesikali semolekyuli, esahlula imixube yegesi equlethe iimolekyuli ezinobukhulu obuninzi. Ziimolekyuli ezincinci kuneembobo kuphela ezinokudlula; ngelixa iimolekyuli ezinkulu zivaliwe. Ukuba ...Funda ngokugqithisileyo
