Masikelo a Molecular: Phunzirani Za Magwiritsidwe Awo ndi Kagwiritsidwe Ntchito Kawo

 

dziwitsani

 Masifa a mamolekyu, omwe amadziwikanso kuti ma zeolite opangira, ndi zida za porous zomwe zimasankha mamolekyu adsorb kutengera kukula kwake ndi polarity. Katundu wapaderawa amalolasieve maselokupeza ntchito zosiyanasiyana m'mafakitale osiyanasiyana. M'nkhaniyi, tikambirana mozama funso lakuti, "Kodi masikelo a molekyulu amagwiritsidwa ntchito bwanji?" ndikuwunika mwatsatanetsatane mapulogalamu omwe wamba.

 

Mapulogalamu a mafakitale

Chimodzi mwazinthu zofunika kwambiri zosefa ma molekyulu ndi m'makampani amafuta ndi gasi. Sieve za mamolekyulu zimagwira ntchito yofunika kwambiri pochotsa chinyezi ndi zonyansa za gasi, zomwe zimapangitsa kuti zikhale zoyenera kuyenda ndi kugwiritsidwa ntchito. Momwemonso, masefa a ma molekyulu amagwiritsidwa ntchito pochotsa Mowa m'thupi komanso poyeretsa ma hydrocarbons, zomwe zimapangitsa kupanga mafuta ndi mankhwala apamwamba kwambiri.

Kuphatikiza apo, sieve zama cell amagwiritsidwa ntchito kwambiri pakulekanitsa mpweya, kuphatikiza kupanga nayitrogeni, mpweya ndi mpweya wina wamakampani. Kuchuluka kwa adsorption kwa masieve a maselo kumathandiza kulekanitsa mpweya ndi mpweya, kutulutsa mpweya wabwino kwambiri womwe umakwaniritsa zofunikira za mafakitale angapo kuphatikizapo zaumoyo, kuwotcherera ndi kudula zitsulo.

M'makampani a petrochemical,sieve maselochitani ngati chothandizira kapena adsorbents panthawi yotembenuka ndi kuyeretsa. Amathandiza kuchotsa zonyansa monga sulfure ndi carbon dioxide ndi kupititsa patsogolo ntchito ya catalysts, kupititsa patsogolo kupanga mankhwala ndi mafuta.

Kugwiritsa ntchito zachilengedwe

Kuthekera kwa ma molekyulu kutengera mamolekyu amadzi kuchokera ku zakumwa ndi mpweya kumawapangitsa kukhala ofunikira pakugwiritsa ntchito zachilengedwe zosiyanasiyana. Mwachitsanzo,sieve maseloamagwiritsidwa ntchito mufiriji ndi makina oziziritsira mpweya kuchotsa madzi, motero amapewa dzimbiri ndi kuzizira.

 

Kuphatikiza apo, ma sieve a molekyulu amagwiritsidwa ntchito kwambiri ngati ma desiccants muzonyamula kuti zinthu monga mankhwala ndi zamagetsi ziume. Maonekedwe a hygroscopic a sieve a ma molekyulu amatsimikizira kusungidwa kwabwino ndikukulitsa moyo wa alumali wazinthu zovutirazi.

 

mapulogalamu azachipatala

Muzachipatala,sieve maselozimagwira ntchito yofunika kwambiri popanga mpweya wamankhwala ndikuchotsa mpweya woipa mu mpweya wotuluka panthawi ya anesthesia. Amathandiza kusamalira mpweya wamankhwala mosamala komanso moyenera, kukonza chisamaliro cha odwala.

 

Pomaliza

Mwachidule, ma sieve a molekyulu ali ndi ntchito zosiyanasiyana ndipo ndi zinthu zofunika kwambiri pa gasi, mafuta, petrochemical, kuteteza chilengedwe, mankhwala ndi mafakitale ena. Kutha kwawo kutsatsa mamolekyu motengera kukula ndi polarity kumawapangitsa kukhala ofunikira kwambiri panjira kuyambira pakutaya madzi m'thupi ndi kuyeretsa mpaka kupatukana ndi mpweya komanso momwe zimachitikira. Pamene kufunikira koyeretsa, matekinoloje ogwira mtima akupitilira kukula, masikelo a ma molekyulu akadali gawo lofunikira pamafakitale ambiri ndi chilengedwe.
