Yintoni kanye kanye iTitanium Dioxide?
I-Titanium dioxide (TiO2)yi-inorganic compound eyenziwe nge-titanium kunye ne-oxygen esebenza njengeyona pigment imhlophe isebenzayo kwimizi-mveliso yanamhlanje. Ngamafutshane, yi-powder emhlophe ecocekileyo ethi, xa ifakwe kwiipeyinti, iiplastiki, iphepha, okanye nayiphi na enye into, inike ubumhlophe obukhethekileyo, ukukhanya, kunye nokungacaci.
I-TiO2 ifezekisa oku ngenxa yesalathisi sayo esiphezulu sokuqaqamba -- ukusuka kwi-2.55 ukuya kwi-2.76 kuxhomekeke kwimo yekristale -- ephezulu kunayo nayiphi na enye i-pigment emhlophe. Ukuthelekisa, i-zinc oxide inesalathisi sokuqaqamba se-2.0, i-calcium carbonate 1.6, kunye ne-talc 1.57. Oku kuthetha ukuba i-TiO2 isasaza ukukhanya okubonakalayo ngokufanelekileyo, yiyo loo nto nokuba incinci iphucula kakhulu amandla okugubungela kunye nokukhanya.
>> Impendulo yeNugget: I-Titanium dioxide (TiO2) yipigment emhlophe engaphiliyo ene-refractive index ephezulu (2.55-2.76) phakathi kwazo zonke iipigment ezimhlophe, nto leyo eyenza ukuba ingabi nakutshintshwa ukuze ibonelele ngobumhlophe, ukukhanya, kunye nokungabonakali kwezinto ezigqunywayo, iiplastiki, iphepha, nezinye izinto.
Ngokwembono yeekhemikhali, iTiO2 izinzile ngendlela emangalisayo. Ayisebenzi kwiiasidi ezininzi, iialkali, okanye izinyibilikisi zendalo phantsi kweemeko eziqhelekileyo. Ayinatyhefu, ayitshi, kwaye ayimelani nokubola kwe-UV -- iipropati ezenza ukuba ikhuseleke ukusetyenziswa kwiipakethe zokutya, izinto zokuthambisa, kwaneepilisi zamayeza, ukongeza kwizicelo zayo eziphambili zoshishino.
Iifom ezimbini zeCrystal: iRutile vs. iAnatase
I-TiO2 ikhona ngokwendalo kwizakhiwo ezintathu zekristale, kodwa zimbini kuphela ezibalulekileyo kwezorhwebo: i-rutile kunye ne-anatase. Umahluko phakathi kwazo awukho nje kwizifundo -- imisela ngokuthe ngqo ukuba loluphi uhlobo umzi-mveliso wakho omele uluodole.
>> Impendulo yeNugget: I-Rutile TiO2 ine-refractive index ephezulu (2.76), ukumelana nemozulu ephezulu, kwaye yeyona ndlela ikhethwayo kwiingubo zangaphandle, iiplastiki, kunye nokusetyenziswa okuhlala ixesha elide. I-Anatase TiO2 ine-refractive index ephantsi kancinci (2.55) kodwa inika umbala omhlophe othambileyo kwaye ixabisa kancinci kwiimveliso zangaphakathi ezifana neepeyinti zephepha kunye nezangaphakathi.
I-Rutile TiO2 imalunga ne-85-90% yemveliso ye-TiO2 yehlabathi ngobuninzi bayo kuba ukuzinza kwayo kwifoto kwenza ukuba ifaneleke ukusetyenziswa ngaphandle. Kwiminyaka yam eli-10 ndisebenza nabavelisi bokugquma, ndisoloko ndibona ukuba iiprojekthi ezichaza amanqanaba e-rutile kwiingubo zoyilo zangaphandle zihlangabezana nezikhalazo ezimbalwa kakhulu zokuphela kombala xa kuthelekiswa neeprojekthi ezazama ukusebenzisa amanqanaba e-anatase ngaphandle.
Umahluko ophambili kwezobuchwepheshe usekwe kumsebenzi we-photocatalytic: i-anatase TiO2 iphantse ibe ngaphezulu ngokuphindwe kalishumi kune-rutile, oko kuthetha ukuba ivelisa ii-free radicals ezingaphezulu xa ivezwa kukukhanya kwe-UV -- ezi radicals zihlasela i-organic binder kwiipeyinti nakwiiplastiki, zibangela ukutshixeka, ukulahleka kwe-gloss, kunye nokunyamalala kombala. Yiyo kanye le nto ii-anatase grades zenziwe ngonyango olongezelelweyo lomphezulu xa zisetyenziswa kuyo nayiphi na indlela ene-UV exposure engalindelekanga.
Isetyenziswa phi iTitanium Dioxide? Iinkampani Eziphambili Ezithandathu
>> Impendulo yeNugget: I-titanium dioxide isetyenziswa kumashishini amathandathu aphambili -- ii-coating (35% yemfuno yehlabathi), iiplastiki (25%), iphepha (12%), ii-inki (5%), irabha, kunye ne-masterbatch -- kunye nomthamo oseleyo oya kwiizicelo ezikhethekileyo ezifana nezimonyo, ukutya, kunye namayeza.
1. Iingubo kunye neepeyinti (35% yeMfuno yeTiO2 yeHlabathi)
Ishishini leengubo zokwaleka lilona lisebenzisa kakhulu iTiO2. Kwindlela eqhelekileyo yokupenda yoyilo, iTiO2 ibandakanya i-15-25% yobunzima befomyula iyonke kwaye ixabisa malunga ne-40-50% yexabiso lezinto ezikrwada. Oku kungenxa yokuba iTiO2 inika amandla okufihla kunye nobumhlophe obujongwa ngabathengi bepeyinti ngamehlo abo.
Ngokwedatha evela kwi-American Coatings Association, imakethi yehlabathi yepeyinti kunye neengubo ichithe malunga ne-2.6 yezigidi zeetoni ze-TiO2 ngo-2025. Kutyelelo lwam kumzi-mveliso kubavelisi beengubo eIndiya naseTurkey, ndiqaphele ukuba nabavelisi bepeyinti abasebenzisa iifomyula zomgangatho wokuqala abayi kuphazamisa umgangatho we-TiO2 -- kuba umgangatho ophantsi we-TiO2 uthetha ukufaka iingubo ezintathu endaweni yezimbini, nto leyo ephinda kabini iindleko zomsebenzi kunye nexesha kubathengi babo.
2. Iiplastiki kunye neMasterbatch (25% yeMfuno yeTiO2 yeHlabathi)
Kwishishini leplastiki, iTiO2 isebenza imisebenzi emibini: inika umbala omhlophe oqaqambileyo abathengi abawulindeleyo kwiimveliso ezifana nemibhobho yePVC, iiprofayili zeefestile, kunye neefilimu zokupakisha, kwaye ikwakhusela i-polymer matrix ekuwohlokeni kwe-UV. ITiO2 ifunxa imisebe ye-UV kwaye iyitshabalalise njengobushushu obungenabungozi, nto leyo eyandisa kakhulu ubomi benkonzo yeemveliso zeplastiki zangaphandle.
Kubavelisi be-masterbatch, amanqanaba okulayisha e-TiO2 adla ngokuba phakathi kwe-50-70% ngobunzima, oko kuthetha ukuba ukusasazeka, ukuhamba kwamanzi, kunye nokuzinza kobushushu be-TiO2 kumisela ngokuthe ngqo ukusebenza kakuhle kwemveliso. I-TiO2 grade enokusasazeka kakubi inokubangela ukuvaleka kwesikrini, iziphene zomphezulu, kunye nokungafani kombala -- iingxaki ezinokubiza umvelisi we-masterbatch amawaka eedola ngosuku ngexesha lokungasebenzi.
3. Ukwenziwa kwephepha (12% yeMfuno ye-TiO2 yeHlabathi)
Kwishishini lephepha, iTiO2 isetyenziswa kakhulu kwiphepha lokuhombisa elikumgangatho ophezulu, iphepha le-laminate, kunye nephepha lebhayibhile apho kufuneka i-opacity ephezulu kubukhulu obuncinci. ITiO2 inika i-opacity ephindwe kalishumi kune-calcium carbonate kwinqanaba elifanayo lokulayisha, nto leyo evumela abenzi bephepha ukuba bavelise iphepha elincinci nelikhaphukhaphu ngaphandle kokunciphisa ukumelana nokuprintwa.
4. Ii-inki zokuprinta, irabha, kunye nezicelo ezikhethekileyo
Kwishishini le-inki yokushicilela, i-TiO2 isebenza njenge-pigment emhlophe esisiseko kwii-inki ze-flexographic kunye ne-gravure zokupakisha okuguquguqukayo. Ngenxa yokuba ubukhulu befilimu ye-inki buncinci kakhulu kunefilimu yepeyinti -- ngesiqhelo yi-1-5 microns xa kuthelekiswa ne-50-100 microns -- uhlobo lwe-TiO2 olusetyenziswa kwii-inki kufuneka lube nokusasazwa kobukhulu be-particle obucolekileyo kakhulu kwaye bufanayo ukuze kufezekiswe ukungabonakali ngokwaneleyo kwii-film weights eziphantsi kangaka.
Kwishishini lerabha, iTiO2 isetyenziswa njengepigment emhlophe kunye ne-reinforcement filler kwiimveliso ezifana namatayara amhlophe eludongeni, izihlangu, kunye nomgangatho zerabha. Iiklasi ze-Anatase zihlala zikhethwa xa kusetyenziswa irabha apho umbala omhlophe othambileyo kancinci uthandeka ngokobuhle kwaye ukumelana nemozulu embi akuyomfuneko iphambili.
Injani iI-Titanium DioxideYenziwe?
>> Impendulo yeNugget: I-TiO2 yenziwa ngeenkqubo ezimbini zoshishino -- inkqubo ye-sulfate (kusetyenziswa i-ilmenite ore kunye ne-sulfuric acid, ivelisa zombini iiklasi ze-rutile kunye ne-anatase) kunye nenkqubo ye-chloride (kusetyenziswa i-rutile ephezulu okanye i-rutile yokwenziwa enegesi ye-chlorine, ivelisa kuphela iiklasi ze-rutile ezinobunyulu obuphezulu kunye nolawulo oluqinileyo lobungakanani bamasuntswana).
Inkqubo ye-sulfate, ebanga malunga ne-40% yemveliso yehlabathi, iqala nge-ilmenite (FeTiO3) egayiweyo kwi-sulfuric acid exineneyo. Le nkqubo iguquguquka ngakumbi -- ingasebenzisa ii-ore ezikumgangatho ophantsi kwaye ivelise imveliso ye-rutile okanye ye-anatase ngokuxhomekeke kwiimeko ze-calcination. Nangona kunjalo, ivelisa iimveliso ezingaphezulu zenkunkuma, ngakumbi i-iron sulfate, ekufuneka ilawulwe ngokurisayikilisha okanye ukulahla.
Inkqubo ye-chloride, ebalelwa malunga ne-60% yemveliso ye-TiO2 yehlabathi, iqala nge-rutile ephezulu okanye i-ilmenite ephuculweyo esabela kwigesi ye-chlorine kubushushu obuphezulu (900-1,000 C) ukuvelisa i-TiCl4, ethi emva koko i-oxidized ukuvelisa i-TiO2 ecocekileyo kakhulu. Inkqubo ye-chloride ivelisa imveliso enokusasazwa kobukhulu beesuntswana eziqinileyo kunye nokukhanya okuphezulu ngokubanzi, kodwa ifuna ukutya okubiza kakhulu kunye nolawulo lwenkqubo oluyinkimbinkimbi.
Apha e-SUN BANG, sigcina ubudlelwane nabavelisi besebenzisa zombini ezi teknoloji, nto leyo esivumela ukuba sicebise imveliso engabizi kakhulu nefanelekileyo ngobuchwephesha kwisicelo somthengi ngamnye endaweni yokuba sivaleleke kwinkqubo enye.
IMarike ye-TiO2 yeHlabathi: Kutheni Oku Kubalulekile kwiShishini Lakho
>> Impendulo yeNugget: Imveliso ye-TiO2 yehlabathi idlule kwi-7.3 yezigidi zeetoni ze-metric ngo-2025, apho iTshayina ivelisa malunga ne-45% yetotali iyonke. I-TiO2 ithathwa njenge-barometer yemisebenzi yemizi-mveliso kuba ukusetyenziswa kwayo kuhambelana ngokuthe ngqo neengubo, ulwakhiwo, kunye nemveliso yokuvelisa.
Ngokutsho kwe-Titanium Dioxide Manufacturers Association (TDMA), imfuno yehlabathi ye-TiO2 ikhule ngesantya sokukhula sonyaka esidibeneyo (CAGR) esimalunga ne-3.5-4.0% kwiminyaka elishumi edlulileyo, eqhutywa ikakhulu kukukhula kwabantu basezidolophini kumazwe asakhasayo. Isakhiwo ngasinye esitsha seeflethi, imoto nganye entsha, kunye nesixhobo ngasinye esitsha sifuna i-TiO2 ndaweni ithile kuluhlu lwayo lokubonelela.
