Ukuqonda Umahluko phakathi kweRutile, Anatase, kunye neBrookite: Ukutyhila Iimfihlakalo zeTitanium Dioxide

Intshayelelo:

I-Titanium dioxide (I-TiO2) sesona sixhobo sisetyenziswa kakhulu kwaye sisetyenziswa kakhulu kwimizi-mveliso eyahlukahlukeneyo, kuquka iipeyinti nezaleko, izinto zokuthambisa, kwanokutya.Kukho izakhiwo ezintathu eziphambili zekristale kusapho lweTiO2:rutile anatase kunye nebrookite.Ukuqonda umahluko phakathi kwezi zakhiwo kubalulekile ekusebenziseni iimpawu zazo ezizodwa kunye nokuvula amandla azo.Kule bhlog, siza kujonga ngakumbi kwiipropati kunye nokusetyenziswa kwe-rutile, i-anatase, kunye ne-brookite, ityhila ezi ntlobo zintathu zinomdla ze-titanium dioxide.

1. Rutile Tio2:

I-Rutile yeyona ndlela ininzi kwaye izinzile ye-titanium dioxide.Ibonakaliswe yi-tetragonal crystal structure, equkethe i-octahedron esondeleyo.Olu lungiselelo lwekristale lunika ukuxhathisa okugqwesileyo kwimitha ye-UV, kuyenza ibe lolona khetho lubalaseleyo lokwenziwa kwe-sunscreen kunye ne-UV-blocking coatings.Rutile Tio2Isalathiso serefriactive ephezulu sikwanyusa ukungafihli kunye nokuqaqamba, iyenza ilungele ukuvelisa ipeyinti ekumgangatho ophezulu nee-inki zoshicilelo.Ukongezelela, ngenxa yokuzinza kwayo kweekhemikhali eziphezulu, i-Rutile Tio2 inezicelo kwiinkqubo zenkxaso ye-catalyst, i-ceramics, kunye nezixhobo zokukhanya.

2. Anatase Tio2:

I-Anatase yenye indlela eqhelekileyo yekristale ye-titanium dioxide kwaye inesakhiwo esilula se-tetragonal.Xa kuthelekiswa ne-rutile,Anatase Tio2inoxinaniso olusezantsi kunye nommandla ophezulu, unika umsebenzi ophezulu we-photocatalytic.Ke ngoko, isetyenziswa kakhulu kwizicelo zefotocatalytic ezifana nokucocwa kwamanzi nomoya, iindawo zokuzicoca, kunye nokucocwa kwamanzi amdaka.I-Anatase iphinda isetyenziswe njenge-agent emhlophe ekwenzeni iphepha kunye nenkxaso ye-catalyst kwiindlela ezahlukeneyo zemichiza.Ngaphezu koko, iimpawu zayo zombane ezikhethekileyo zenza ukuba zilungele ukuveliswa kweeseli zelanga zelanga kunye nezinzwa.

3. Brookite Tio2:

I-Brookite yindlela encinci ye-titanium dioxide kwaye ine-orthorhombic crystal structure ehluke kakhulu kwi-tetragonal izakhiwo ze-rutile kunye ne-anatase.I-Brookite idla ngokuvela kunye nezinye iifom ezimbini kwaye ineempawu ezidibeneyo.Umsebenzi wayo we-catalytic uphezulu kune-rutile kodwa ungaphantsi kune-anatase, iyenza ibe luncedo kwezinye izicelo zeeseli zelanga.Ukongezelela, i-crystal structure ye-brookite ivumela ukuba isetyenziswe njenge-mineral specimen kwizinto zobucwebe ngenxa yembonakalo enqabileyo kunye neyodwa.

Isiphelo:

Ukushwankathela, izinto ezintathu ze-rutile, i-anatase kunye ne-brookite zinezakhiwo ezahlukeneyo ze-crystal kunye neempawu, kwaye nganye ineenzuzo zayo kunye nokusetyenziswa kwayo.Ukususela ekukhuselweni kwe-UV ukuya kwi-photocatalysis kunye nokunye, ezi ntlobo zetitanium dioxidedlala indima ebalulekileyo kumashishini ahlukeneyo, ukutyhala imida yokusungula izinto ezintsha kunye nokuphucula ubomi bethu bemihla ngemihla.

Ngokuqonda iipropati kunye nokusetyenziswa kwe-rutile, i-anatase kunye ne-brookite, abaphandi kunye neenkampani banokwenza izigqibo ezinolwazi xa bekhetha uhlobo lwe-titanium dioxide olulungele iimfuno zabo ezithile, ukuqinisekisa ukusebenza kakuhle kunye neziphumo ezilindelekileyo.
