Zeolite Natural: Iimpawu, Iimpawu, Sebenzisa Industrial

Zeolite libhekisela kwiqela kwezimbiwa lentlenga mlilo, ukuba nobuninzi iintlobo zezakhiwo. Ezi zilandelayo zeolites zixhaphakileyo zendalo: lomonit, erionite, ferrierite, chabazite kunye nabanye. Ngokwembono chemistry, zeolites ezi non-stoichiometric isakhiwo iikhompawundi njengekristale. Iimpawu ezizodwa izimbiwa ngokupheleleyo ngenxa isakhiwo zangaphakathi - lwendibaniso eziphezulu tetrahedra aluminiyamu oxide kunye nefom lesilicon amajelo amaninzi ezaliswe iimolekyuli zamanzi, kunye amasuntswana kakuhle ityala.

iimpawu lomgangatho zeolites baziwa kangangamakhulu eminyaka. Kumaxesha amandulo abantu kongezelelwa rocks zeolite aqulethe ekutyeni, esazi malunga ngamandla aphilisayo kwezimbiwa. Kwiinkulungwane ezadlulayo micinga baphawula ukuba isityalo kumhlaba uhlaza kunye iidipozithi of zeolite.

Kude kube kamva nje, imveliso woshishino zeolite zendalo zange kwenziwa, i izimbiwa kuhlelwe kusetyenziswa - zeolites zokwenziwa. Ukusetyenziswa zeolites isekelwe phezu kwiipropati imichiza ngokwasemzimbeni ngenxa wokumbiwa. Okokuqala - yinto adsorbent yendalo. Inkqubo emzimbeni iguqulelwa ibe microporous into nezimbiwa kunye nenkqubo nemingxuma lwangaphakathi, nto leyo kusichukumisa molecule iikhompawundi eziphilayo nezingaphiliyo. It anazo umthamo omkhulu izifunxi ingubo iigesi kunye ulwelo ezahlukeneyo.

Izazinzulu ziye sungula uphando iipropati ezibubhayoloji neziphathekayo kunye imichiza yezi kwezimbiwa ngenjongo izicelo mveliso. Xa ukutya kunye noshishino lwezolimo, zeolites zisetyenziselwa ukuvelisa iimveliso indalo. Eyona isicelo zeolite:

• enemfuyo, iinkukhu, njengokuba additive feed kwi feed, deodorizing soPhuculo iinkomo;
• njengento lokucoca ekulungelelaniseni kweenkqubo kwamanzi;
• ngokuba adsorption of izinto eziyityhefu;
• kwi unyango amdaka avela kwimizi;
• kushishino - ukuveliswa eziphathekayo, isamente, irabha, iplastiki, iphepha nekhadibhodi;
• amayeza njengoko hemosorbents kunye nezinye ubuchwepheshe sorption.

Umthamo yehlabathi kwimveliso zeolite liyanda minyaka 20-25%. Uqwalaselo zeolite ngendlela engazange mveliso yenziwa phezu zonke iidipozithi kwezimbiwa. Ngaloo yinxenye idiphozithi wawusembiwa iliwa ukuya kwisiqulatho abakhoyo asebenzayo 60%. Ngokomthetho eli nani lingaphumi ngentla-50%. Ngaloo ndlela, ukusetyenziswa kwezimbiwa zeolite-mveliso eyahlukeneyo ukusebenza evelisa umiselwa ipesenti enkulu isithako esebenzayo.
