I-Titanium Dioxide yokuMakisha eziNdleleni

I-Titanium dioxide (TiO2) yiminerali eyenzeka ngokwemvelo esetyenziswa ngokuqhelekileyo kumashishini ahlukeneyo. Xa kuziwa kumanqaku endlela, i-titanium dioxide sisithako esiyimfuneko ngenxa yeempawu zayo ezizodwa. Isalathiso saso esiphezulu se-refractive siqinisekisa ukukhanya okugqwesileyo kunye nokubonakala, okwenza iimpawu zendlela zibonakale kakhulu nakwiimeko eziphantsi zokukhanya. Oku kubaluleke ngakumbi xa uqhuba ebusuku okanye kwiimeko zemozulu ezimbi apho ukubonakala kuncitshiswa kakhulu.

Ukongeza kokubonakala okuphezulu, i-titanium dioxide inika ukuqina okuhlala ixesha elide. Ukuvezwa kweempawu zendlela kwiimeko ezinzima zokusingqongileyo ezifana netrafikhi enzima, ubushushu obugqithisileyo kunye nemitha ye-UV kunokubangela ukuwohloka ngokukhawuleza. Nangona kunjalo, iimpawu zendlela eziqulethe i-TiO2 zixhathisa kakhulu ekuphelelweni, ukukrazula kunye nokuguga okubangelwa zezi zinto, ziqinisekisa ubomi obude benkonzo kunye neendleko eziphantsi zokulondolozwa.

Enye yeenzuzo eziphambili zokusebenzisa i-titanium dioxide ekuphawulweni kwendlela kukuvumelana kwayo nokusingqongileyo. Ngokungafaniyo nezinye ii-pigments, i-titanium dioxide ayinayo ityhefu, ayinabungozi kwaye ayibeki mngcipheko wempilo kokusingqongileyo okanye kubasebenzi. Ukongeza, imiqondiso yendlela esekwe kwi-titanium dioxide ayikhuphi iikhemikhali ezinobungozi emoyeni, nto leyo ezenza zibe lukhetho oluzinzileyo lweziseko zothutho.

Ukongezelela, i-titanium dioxide inamandla okubonakalisa kunye nokusabalalisa ukukhanya, ukunciphisa imfuno yokukhanya okongeziweyo endleleni. Oku akukongi amandla kuphela kwaye kukhuthaze uzinzo, kukwaphucula ukubonakala kwabaqhubi nabahambi ngeenyawo.

Ngokwesicelo, i-titanium dioxide inokufakwa ngokulula kwizinto ezahlukeneyo zokumakisha zendlela ezifana neepeyinti, i-thermoplastics kunye ne-epoxies. Ingasetyenziselwa iintlobo zeempawu zendlela, kubandakanywa i-centrallines, i-edgelines, i-crosswalks kunye neempawu, ukuqinisekisa ukubonakala okuhambelanayo kunye nobunye kuthungelwano lwendlela.

Kuyilo loyilo lwepeyinti, ngaphezu kokukhetha ibakala elifanelekileyo le-titanium dioxide, omnye umcimbi obalulekileyo yindlela yokumisela ukusetyenziswa ngokufanelekileyo kwe-titanium dioxide. Oku kuxhomekeke kwimfuno yokwaleka kokugquma kodwa kuthengiswa ngezinye izinto ezifana ne-PVC, ukumanzisa kunye nokusabalalisa, ubukhulu befilimu, umxholo wezinto eziqinileyo kunye nobukho bezinye ii-pigments ezinemibala. Ukufudumala kwegumbi lokunyanga i-solvent-based white coatings, umxholo we-titanium dioxide ungakhethwa kwi-350kg / 1000L yokugqoka umgangatho ophezulu ukuya kwi-240kg / 1000L yeengubo zezoqoqosho xa i-PVC i-17.5% okanye umlinganiselo we-0.75: 1. Idosi eqinileyo yi-70% ~ 50%; kuba ipeyinti zokuhombisa latex, xa PVC CPVC, isixa titanium dioxide ingancitshiswa ngakumbi kunye nokwanda amandla yokufihla owomileyo. Kwezinye iifomyulo zokugquma kwezoqoqosho, inani le-titanium dioxide lingancitshiswa libe yi-20kg/1000L. Kwizakhiwo eziphakamileyo zodonga lwangaphandle lwangaphandle, umxholo we-titanium dioxide unokuncitshiswa kwinqanaba elithile, kwaye ukunamathela kwefilimu yokugqoka kunokwandiswa.
