Kushandiswa kweTitanium Dioxide muindasitiri yepurasitiki

Kushandiswa kwetitanium dioxide (TiO ₂) muindasitiri yepurasitiki kunonyanya kuratidzwa muzvinhu zvinotevera: sepigment huru, inogona kuvandudza kuchena uye simba rekufukidza zvigadzirwa zvepurasitiki, kuwana chiedza chakawanda kuburikidza nekupararira uye kupinza chiedza, kunyanya mumaresini anotsvedza, titanium dioxide ine dhayamita ye0.15-0.3 μ m inogona kugadzira chikamu chebhuruu chemashure kuti chiwedzere mhedzisiro yekufukidza; Panguva imwe chete, titanium dioxide inonyatsononoka kukwegura kwepurasitiki uye inovandudza kusimba kwemamiriro ekunze nekupinza chiedza cheultraviolet. Zvigadzirwa zvekunze zvinoda kushandisa rutile type uye kuwedzerwa matekinoroji ekurapa pamusoro akadai sesilicon, aluminium, uye zirconium kudzivirira matambudziko emaburi anokonzerwa nekubuda kwemvura panguva yekugadzirisa tembiricha yepamusoro; Panyaya yekugadzikana kwekupisa, titanium dioxide inogona kuvandudza mashandiro epurasitiki munzvimbo dzine tembiricha yepamusoro nekuderedza mashandiro e photochemical kuburikidza nenzira dzekugadzirisa pamusoro (senge inorganic coating), kuve nechokwadi chekuti zvigadzirwa zvine simba remuchina uye kugara kwenguva refu kwemavara mumamiriro ezvinhu akaomarara. Maitiro ekushandisa titanium dioxide akasiyana pamhando dzakasiyana dzepurasitiki - mapolyolefins anoda kutariswa kuti anogona kupararira sei uye kudzivirira kusviba kwemavara, zvinhu zvakaoma zvePVC zvinoenderana nekugona kwetitanium dioxide kudzivirira kusviba, nepo ABS ichinyanya kutarisa pakuenzanisa maitiro ekuona uye emakanika. Mukushandiswa kwakajairika, huwandu hwetitanium dioxide inowedzerwa hunowanzo dzorwa pa3% ~ 5% kuti huenzane nekushanda zvakanaka, uye huwandu hwemavara akakosha hunogona kusvika 40% ~ 70%; Nekugadzirisa kugoverwa kwehukuru hwezvidimbu (senge 2-35 μ m) uye maitiro ekurapa pamusoro, Bontecn Group China titanium dioxide yakawana kuchena kwakanyanya, kuramba mamiriro ekunze, uye kugadzikana kwekugadzirisa munzvimbo dzakadai semafirimu epurasitiki, ma profiles emasuo nemahwindo, uye zvikamu zvemotokari.
