Basa re titanium dioxide muzvigadzirwa zverabha

1, Mabasa epakati
Kupenda uye Kuchenesa
Ipa zvigadzirwa zverabha mavara machena kana anopenya, wedzera runako rwechitarisiko, uye wedzera kunaka kwechigadzirwa.
Anti UV uye anti-kukwegura
Inwa mwaranzi ye ultraviolet, inononoka kutsvuka kwerabha, kutsemuka, uye kudzikira kwekushanda kwayo kunokonzerwa nekuratidzwa nechiedza, uye inowedzera hupenyu hwayo hwekushanda.
Nyaya: Kuwedzera rutile titanium dioxide kumatayi emotokari kunogona kuwedzera simba rawo rekudzivirira ozone nemwaranzi ye ultraviolet.
Kusimbisa uye kuzadza
Wedzera simba remuchina (sekusimba kwekusimba uye kuramba kupfeka) kwezvigadzirwa zverabha, uye zvishandise sezvishandiso zvinozadza zvinhu kuti uderedze mari yekugadzira.
2, nzvimbo dzakakamurwa dzekushandisa
Matayi emota
Rutile yakanyanya, yakasanganiswa nerudzi rwerutile (senge R-350 grade) kuti iwedzere kusimba kwemamiriro ekunze uye kudzivirira kukwegura kwematairi kunokonzerwa nemwaranzi ye ultraviolet.
Zvinodiwa zvezuva nezuva uye zvigadzirwa zvemaindasitiri
Shangu/Magirovhosi: Yakapinza titanium dioxide inopa kuchena uye kudzivirira zuva;
Midziyo yemitambo/pasi perabha: inowedzera runako rwepamusoro uye kuramba kupfeka.
3, Kiyi yekuvandudza mashandiro
Sarudzo yemhando yekristaro
Rudzi rwetitanium rwakapinza: rudzi rwepasi rose, mutengo wakaderera, runoshandiswa pakugadzira zvigadzirwa zvine ruvara rwakajeka;
Rutile type: Munzvimbo dzine mamiriro ekunze akasimba (senge mativi ematairi), ine simba rakanaka rekudzivirira kutsvuka kweyero.
Tekinoroji yekurapa pamusoro
Kurapa kwesilicon/aruminiyamu coating passivation (senge titanium dioxide R-350) kunogona kuderedza reaction nerabha additives uye kudzivirira yero.
Kushandira pamwe kwefomura
Zvinosanganiswa ne carbon black uye zvinorwisa kukwegura kuti zvienzane nemutengo uye kuramba kupfeka;
Kudzora saizi yezvikamu (zvidimbu zvidiki) kunoita kuti zvipararire zvakaenzana uye zvinochengetedza rabha ichipfava.
4, Kudzivirira
Huwandu hwekuwedzera: Huwandu hwakawandisa hunogona kukanganisa ductility yerabha uye hunoda kugadziriswa zvichienderana nezvinodiwa nechigadzirwa;
Kuchengetedza: Inoda nzvimbo yakaoma kudzivirira kunyungudika kwehunyoro uye kuungana kwevhu;
Hushamwari kune zvakatipoteredza: Inosangana nezvinodiwa zvisina chepfu uye yakakodzera zvigadzirwa zvekusangana zvakaita semagirovhosi.
Cherechedza: Titanium dioxide ine basa rakapetwa kaviri sepigment uye functional filler murabha, ine high refractive index (rutile type ≈ 2.71) uye chemical stability ndiyo hwaro hwekushanda kwayo.
