Kugwiritsa ntchito njira yoyeretsera sieve ya molekyulu mu gawo lolekanitsa mpweya
Mpweya wopanikizika ndi compressor ya mpweya umagwiritsa ntchito alumina yolumikizidwa ndi adsorbent ndi sefa ya molekyulu kuti ichotse madzi, carbon dioxide, acetylene, ndi zina zotero. Monga sefa ya adsorbent, sefa ya molekyulu imatha kuyamwa mpweya wina wambiri, ndipo imakhala ndi chizolowezi chodziwikiratu mu njira yoyamwa. Pamene m...Werengani zambiri -
Kodi zeolite yachilengedwe ndi poizoni? Kodi imadyedwa?
Kodi zeolite yachilengedwe ndi poizoni? Kodi imadyedwa? Mu 1986, ngozi ya ku Chernobyl inachititsa kuti tawuni yonse yokongola iwonongedwe usiku wonse, koma mwamwayi, ogwira ntchito anathawa, ndipo anthu ena okha ndi omwe anavulala ndi kulumala chifukwa cha ngoziyi. Inalinso ngozi yaikulu yomwe inachititsa...Werengani zambiri -
Zinthu zazikulu zomwe makampani angapo otchuka padziko lonse lapansi amapanga popanga zinthu zothandizira
Ndi kupititsa patsogolo kosalekeza kwa mphamvu yoyeretsera padziko lonse lapansi, miyezo yokhwima kwambiri yamafuta, komanso kuwonjezeka kosalekeza kwa kufunikira kwa zinthu zopangira mankhwala, kugwiritsa ntchito zinthu zoyeretsera kwakhala kukukula mosalekeza. Pakati pa izi, kukula kwachangu kwambiri kuli mu ...Werengani zambiri -

Sefa ya molekyulu ndi chinthu chokhala ndi mabowo (mabowo ang'onoang'ono kwambiri) ofanana kukula
Sefa ya mamolekyulu ndi chinthu chokhala ndi ma pores (mabowo ang'onoang'ono kwambiri) ofanana kukula. Ma pores awa ali ndi kukula kofanana ndi mamolekyu ang'onoang'ono, motero mamolekyu akuluakulu sangalowe kapena kulowetsedwa, pomwe mamolekyu ang'onoang'ono amatha. Pamene chisakanizo cha mamolekyulu chimasuntha kudzera mu ...Werengani zambiri -

Kodi Maselo a Molecular Sieves amagwira ntchito bwanji?
Sefa ya molekyulu ndi chinthu chokhala ndi mabowo omwe ali ndi mabowo ang'onoang'ono kwambiri, ofanana. Imagwira ntchito ngati sefa ya kukhitchini, kupatula pa sikelo ya molekyulu, kulekanitsa zosakaniza za mpweya zomwe zili ndi mamolekyu akuluakulu. Mamolekyu ang'onoang'ono okha kuposa ma pores ndi omwe angadutse; pomwe mamolekyu akuluakulu amatsekedwa. Ngati ...Werengani zambiri
