Ndeapi mabasa makuru etitanium dioxide pamapombi?

1, Mabasa epakati
Kuvandudza kusimba kwemamiriro ekunze uye kusimba kwekukura: titanium dioxide (TiO2) inogona kunonotsa kukwegura kwemapaipi (akadai semapaipi ePVC nePE) munzvimbo dzekunze, kudzivirira kutsvuka, kusviba uye kuchekwa pamusoro, uye kuwedzera hupenyu hwebasa nekupinza chiedza che ultraviolet uye kudzivirira kuitika kwe photochemical. Rutile titanium dioxide ine simba rakasimba rekudzivirira UV nekuda kwekurapa kuputira (senge zirconia/alumina).
Kuvandudza kufukidzwa uye kuchena: Hunhu hwe high refractive index hunoita kuti titanium dioxide iparadzire chiedza chinoonekwa, ichifukidza ruvara rwepasi pepombi substrate (senge ruvara rweyero yakajeka rwepasi pePVC), zvichiita kuti chigadzirwa chive chichena, ruvara rwakafanana, uye chitarisiko chakajeka. Muenzaniso webhuruu phase base tone unogona kugadzirisa kuchena kwekuona.
Kuvandudza mashandiro ekugadzirisa uye kugadzikana: Kusanyanya kupinza mafuta (≤ 23g/100g) uye nzira dzekugadzirisa pamusoro pemvura (dzakadai sekuwedzera chiedza TR-36) zvinowedzera kupararira kwetitanium dioxide mupurasitiki inonyunguduka, kuderedza kushandiswa kwesimba rekugadzira, uye kudzivirira zvikanganiso zvakaita semaburi nemavanga ekuyerera kwemvura pamusoro pemapaipi.
2, zvinodiwa zvekushandisa zvakakosha
Kugadziriswa kwekudzivirira mamiriro ekunze: Mapaipi ekunze anofanira kushandisa rutile titanium dioxide (yakadai seSR-236, R-838), iyo ine coating inogona kuramba kuora kwe resin kunokonzerwa neUV catalysis; Rudzi rwetitanium rwakapinza runowanzo kurumidza kukwegura kwepaipi nekuda kwekusagadzikana kwemamiriro ekunze.
Ruvara uye kudzora simbi inorema: Titanium dioxide yechikamu chebhuruu (yakadai seR-248) inogona kurwisa ruvara rweyero rwemapaipi ePVC uye kuvandudza kuchena kwawo; Kutarisirwa kunofanirwa kupihwa kune huwandu hwesimbi inorema (yakadai sechromium nelead) yetitanium dioxide mumapaipi ane chekuita nemvura kudzivirira kusvibisa hunhu hwemvura.
Kuenderana kwekuwedzera: Mapaipi ePVC ane zvinhu zvinosimbisa munyu we lead anofanira kusarudzwa nemamodheru akakodzera kudzivirira kusawirirana pakati pe titanium dioxide nezvinodzivirira.
4, Mazano ekushandisa
Huwandu hwekuwedzera: kazhinji 3% -5% yehuremu hwezvinhu, zvinogadziriswa zvichienderana nezvinodiwa zvekudzivirira mamiriro ekunze;
Dziviriro pakushanda: Kuchengetedza hunyoro kunodiwa, uye magirovhosi ekudzivirira nemagogorosi zvinofanira kupfekwa panguva yekushanda.
Cherechedza: Kufamba kwesimbi ine titanium dioxide mumvura kunofanirwa kuongororwa zvakasimba kuitira kuti pave nechokwadi chekuti mitemo yehutsanana inotevedzwa.
