Zirconium hydroxideyinto ebalulekileyo ye-inorganic compound eye yatsala ingqalelo enkulu kumashishini ahlukeneyo ngenxa yeempawu zayo ezizodwa kunye noluhlu olubanzi lwezicelo.Eli nqaku lijolise ekungeneni kwihlabathi elinomdla lei-zirconium hydroxidekwaye ikhanyise ukusetyenziswa kwayo kwiinkalo ezahlukeneyo.
Zirconium hydroxide, kunye nefomula yemichizaZr(OH)4,yikristale emhlophe eqinileyo enganyibilikiyo emanzini.Ithathwe ngokuyinhloko kwiityuwa ze-zirconium ezifana ne-zirconium oxychloride okanye i-zirconium sulfate nge-hydroxide precipitation.Inkqubo iguqula ityuwa ye-zirconium kwifom yayo ye-hydroxide, ityhila iimpawu zayo ezininzi.
Enye yosetyenziso oluphambili lwei-zirconium hydroxideikwinkalo ye-catalysis.Le khompawundi isebenza njenge-catalyst esebenzayo kwiintlobo ezahlukeneyo zeekhemikhali.Indawo yayo ephezulu kunye neepropathi zeLewis acid ziyenza ibe lolona khetho lubalaseleyo kwi-heterogeneous catalysis.Zirconium hydroxideisetyenziswe ngokubanzi njenge-catalyst kwi-organic synthesis, ngakumbi kwimveliso ye-esters, i-ethers kunye ne-alcohol.
Ukwengeza,i-zirconium hydroxideinokusetyenziswa kwakhona njengento yokunqanda ilangatye.Xa ifakwe kwiipolymers ezifana ne-polyurethane okanye i-epoxy, iphucula iimpawu zabo zokunqanda ilangatye.Ngokukhupha umphunga wamanzi kunye nokuthintela ukuveliswa kweegesi ezinokutsha ngexesha lokutsha,i-zirconium hydroxideisebenza njengesithintelo somlilo kwaye iphucula ukhuseleko kumashishini ahlukeneyo kuquka ukwakhiwa kunye neemoto.
Iimpawu zomphezulu ezizodwa zei-zirconium hydroxideikhokelela ekusebenziseni kwayo kwintsimi ye-adsorption.Ngommandla wayo omkhulu, iyakwazi ukuthengisa iimolekyuli ezahlukeneyo kumphezulu wayo, iyenza ibe luncedo ekucoceni amanzi amdaka kunye nokususa isinyithi esinzima.Zirconium hydroxideIi-adsorbents ezisekelwe kwi-adsorbents zibonise ukusebenza kakuhle ekususeni ukungcola okufana ne-arsenic, i-lead kunye ne-nickel kwimithombo yamanzi, ukuphucula umgangatho wamanzi jikelele kunye nokukhusela indalo.
Olunye usetyenziso olunomdla lwei-zirconium hydroxideikwintsimi yeeseramikhi.Ngenxa yokuzinza kwayo kwe-thermal kunye ne-refractive index ephezulu,i-zirconium hydroxideinokusetyenziswa njenge-opacifier kwi-ceramic glazes.Inika i-opacity kunye nomhlophe kwimveliso yokugqibela.Ukongeza,i-zirconium hydroxide-i-ceramics esekelwe isetyenziswe kukufakelwa kwamazinyo ngenxa ye-biocompatibility yabo kunye nokuxhathisa ukubola.
Ukwengeza,i-zirconium hydroxideidlala indima ebalulekileyo kwimveliso ye-zirconium-based compounds.Ngokulawula ukufudumeza kunye nokubala kwei-zirconium hydroxide, i-zirconium oxide (ZrO2) inokufumaneka.Le oxide, eyaziwa ngokuba yi-zirconia, yinto eguquguqukayo esetyenziswa ngokubanzi ukwenza iiseramics, iiseli eziqinileyo zeoksidi yamafutha, kunye namatye anqabileyo okwenziwa.
Kule minyaka yangoku,i-zirconium hydroxideiinanoparticles ziye zatsala ingqalelo kwinkalo yezonyango.Ezi nanoparticles zineempawu ezizodwa ze-physicochemical kwaye zibonisa amandla kwiinkqubo zokuhanjiswa kweziyobisi, i-antimicrobial coatings, kunye ne-imaging technologies.Abaphandi baphonononga i-biocompatibility kunye ne-controlled-release capabilities yei-zirconium hydroxidei-nanoparticles yonyango olujoliswe kuyo kunye nokuxilongwa.
Isishwankathelo,i-zirconium hydroxideYikhompawundi eguquguqukayo enoluhlu olubanzi lwezicelo kumashishini amaninzi.Ukusuka kwi-catalysis ukuya kwi-flame retadancy, i-adsorption ukuya kwi-ceramics, kunye neyeza, ukuguquguquka kwayo kunye neempawu ezizodwa ziyenza ibe yinto efunwa kakhulu.Njengoko izazinzulu ziqhubeka nokufumanisa ukusetyenziswa okutsha kwei-zirconium hydroxide, ukubaluleka kwayo kwiinkalo ezahlukeneyo kuya kuqhubeka kusanda, kube negalelo ekuphuculweni kobugcisa, ukukhuselwa kwendalo kunye nenzululwazi yezonyango.
