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, ukutshitshwa 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 lwamadonga, umxholo we-titanium dioxide unokuncitshiswa kwinqanaba elithile, kwaye ukunamathela kwefilimu yokugqoka kunokwandiswa.
