Mtundu wa Rutile
Titanium dioxide ndi inorganic chemical raw material, yomwe imagwiritsidwa ntchito kwambiri popanga mafakitale monga zokutira, mapulasitiki, mphira, kupanga mapepala, inki zosindikizira, ulusi wamankhwala, ndi zodzoladzola. Titanium dioxide ili ndi mitundu iwiri ya kristalo: rutile ndi anatase. Rutile titanium dioxide, ndiko kuti, R-mtundu wa titaniyamu woipa; anatase titanium dioxide, ndiko kuti, mtundu wa A-titanium dioxide.
Rutile titanium dioxide ili ndi zinthu zabwino kwambiri monga kukana kutentha kwambiri, kukana kutentha pang'ono, kukana kwa dzimbiri, mphamvu yayikulu, ndi mphamvu yokoka yaying'ono. Poyerekeza ndi anatase titanium dioxide, imakhala ndi kukana kwanyengo komanso kuchita bwino kwa photooxidative. Mtundu wa Rutile (mtundu wa R) uli ndi makulidwe a 4.26g/cm3 ndi index refractive ya 2.72. R-mtundu wa titaniyamu woipa ali ndi makhalidwe abwino kukana nyengo, madzi kukana ndi zovuta kutembenukira chikasu. Rutile titaniyamu woipa ali zambiri ubwino zosiyanasiyana ntchito. Mwachitsanzo, chifukwa cha kapangidwe kake kake, mtundu wa pigment umene umatulutsa umakhala wosasunthika komanso suvuta kuukongoletsa. Zili ndi mphamvu zokongoletsa zamphamvu ndipo siziwononga kumtunda. Mtundu wapakati, ndipo mtundu wake ndi wowala, osati wosavuta kuzimiririka. -
Anatase
Titanium dioxide ndi inorganic chemical raw material, yomwe imagwiritsidwa ntchito kwambiri popanga mafakitale monga zokutira, mapulasitiki, mphira, kupanga mapepala, inki zosindikizira, ulusi wamankhwala, ndi zodzoladzola. Titanium dioxide ili ndi mitundu iwiri ya kristalo: rutile ndi anatase. Rutile titanium dioxide, ndiko kuti, R-mtundu wa titaniyamu woipa; anatase titanium dioxide, ndiko kuti, mtundu wa A-titanium dioxide.
Titaniyamu yamtundu wa titaniyamu woipa ndi wa pigment-grade titanium dioxide, yomwe imakhala ndi mphamvu zobisala, mphamvu zopangira kwambiri, zotsutsa kukalamba komanso kukana nyengo yabwino. Anatase titaniyamu woipa, mankhwala dzina titaniyamu woipa, molekyulu chilinganizo Ti02, molekyulu kulemera 79.88. ufa woyera, kachulukidwe wachibale 3.84. Kukhalitsa sikuli bwino ngati rutile titaniyamu woipa, kukana kuwala ndi osauka, ndipo wosanjikiza zomatira n'zosavuta pulverized pambuyo pamodzi ndi utomoni. Choncho, nthawi zambiri amagwiritsidwa ntchito pazinthu zamkati, ndiko kuti, amagwiritsidwa ntchito makamaka pazinthu zomwe sizidutsa dzuwa.
