Semushandisi wechipiri mukurusa wetitanium dioxide, indasitiri yepurasitiki ndiyo inokurumidza kukura mumunda mumakore achangopfuura, ine avhareji yegore rekukura kwe6%.Pakati peanopfuura 500 titanium dioxide mamakisi munyika, anopfuura 50 mamakisi akatsaurirwa kumapurasitiki.Kushandiswa kwetitanium dioxide muzvigadzirwa zvepurasitiki, pamusoro pekushandisa simba rayo rekuvanda, simba guru rechromatic uye zvimwe pigment properties, inogonawo kuvandudza kupisa kwekushisa, chiedza chekudzivirira uye kusagadzikana kwemamiriro ekunze ezvigadzirwa zvepurasitiki, kuitira kuti zvigadzirwa zvepurasitiki zvidzivirirwe kubva. UV chiedza.Kupinda, kunatsiridza michina uye magetsi ezvigadzirwa zvepurasitiki.
Sezvo zvigadzirwa zvepurasitiki zvakakora kupfuura pendi neingi, hazvidi kuwanda kwehuwandu hwemavara epigment, uye zvakare ine simba rekuhwanda uye simba rakasimba rekuita, uye huwandu hwese hwese hunongova 3% kusvika 5%.Inoshandiswa munenge yose ye thermosetting uye thermoplastic mapurasitiki, akadai se polyolefins (kunyanya pasi-density polyethylene), polystyrene, ABS, polyvinyl chloride, nezvimwewo. Inogona kusanganiswa ne resin yakaoma poda kana nekuwedzera.Chikamu chemvura cheplasticizer chakasanganiswa, uye mamwe anoshandiswa mushure mekugadzirisa titanium dioxide mu masterbatch.

Yakanyatso shandiswa ongororo yetitanium dioxide muindasitiri yepurasitiki uye ruvara masterbatch indasitiri

Yakawanda yetitanium dioxide yemapurasitiki ine saizi yakanaka.Kazhinji, saizi yetitanium dhaidhi yehuputi ndeye 0.2 ~ 0.4μm, nepo saizi yetitanium dioxide yemapurasitiki ndeye 0.15 ~ 0.3μm, kuitira kuti bhuruu inogona kuwanikwa.Mazhinji resin ane yero chikamu kana resin ari nyore kutsvuka ane masking maitiro.

Titanium dioxide yemapurasitiki akajairwa kazhinji haaitirwe kurapwa kwepamusoro, nekuti titanium dioxide yakavharwa nezvinhu zvisina kugadzirwa senge zvakajairwa hydrated alumina, kana hunyoro hwehukama huri 60%, iyo adsorption yakaenzana mvura inenge 1%, apo plastiki inosvinwa pakupisa kwakanyanya. .Panguva yekugadzira, kubuda kwemvura kuchaita kuti pores ionekwe pane yakatsetseka yepurasitiki.Iyi mhando yetitanium dioxide isina inorganic coating kazhinji inofanirwa kurapwa organic surface (polyol, silane kana siloxane), nekuti titanium dioxide inoshandiswa kumapurasitiki.Yakasiyana kubva kune titanium dioxide yekuputira, iyo yekutanga inogadziriswa uye yakasanganiswa mune yakaderera-polarity resin nekuveura simba, uye titanium dioxide mushure mekugadziriswa kwepamusoro pevhu inogona kuparadzirwa zvakanaka pasi pesimba rakakodzera rekugera.

Nekuenderera mberi kwekuwedzera kwehuwandu hwekushandisa kwezvigadzirwa zvepurasitiki, zvakawanda zvekunze zvigadzirwa zvepurasitiki, senge magonhi epurasitiki nemahwindo, zvekuvakisa uye zvimwe zvekunze zvigadzirwa zvepurasitiki, zvinewo zvakakwirira zvinodikanwa zvekuramba mamiriro ekunze.Mukuwedzera kune kushandiswa kwe rutile titanium dioxide, kurapwa kwepamusoro kunodiwawo.Uku kurapwa kwepamusoro kazhinji hakuwedzere zinc, chete silicon, aluminium, zirconium, nezvimwe zvinowedzerwa.Silicon ine hydrophilic uye dehumidifying effect, iyo inogona kudzivirira kuumbwa kwepores nekuda kwekubuda kwemvura apo plastiki inobudiswa pakushisa kwepamusoro, asi huwandu hweaya epamusoro ekurapa mishonga inowanzosava yakawandisa.
