Hoʻomaka a me nā ʻano nui o ka Titanium Dioxide

ʻO ka Titanium dioxide (TiO2) kahi huahana kemika inorganic koʻikoʻi, nona nā hoʻohana koʻikoʻi i ka uhi ʻana, ka inika, ka hana pepa, ka palaki palaki, ka fiber kemika, ka seramika a me nā ʻoihana ʻē aʻe. ʻO Titanium dioxide (inoa Pelekane: titanium dioxide) he puaʻa keʻokeʻo nona ka mea nui he titanium dioxide (TiO2). ʻO ka inoa ʻepekema ʻo titanium dioxide (titanium dioxide), a ʻo ka molecular formula ʻo TiO2. He pūhui polycrystalline nona nā ʻāpana i hoʻonohonoho mau ʻia a loaʻa kahi ʻano lattice. ʻO ka liʻiliʻi loa ka liʻiliʻi o ka titanium dioxide. ʻO ke kaʻina hana o ka titanium dioxide he ʻelua ala kaʻina: sulfuric acid method a me chlorination method.

Nā hiʻohiʻona nui:
1) Pili pili
Ma waena o nā puaʻa keʻokeʻo maʻamau, ʻo ka liʻiliʻi loa o ka titanium dioxide. Ma waena o nā puaʻa keʻokeʻo o ke ʻano like, ʻo ka ʻili o ka titanium dioxide ka nui loa a ʻo ka nui o ka puaʻa ka nui loa.
2) Lae hehee a me ka lae paila
Ma muli o ka hoʻololi ʻana o ke ʻano anatase i ʻano rutile i ka wela kiʻekiʻe, ʻaʻole ʻike maoli ka helu heheʻe a me ka paila o anatase titanium dioxide. ʻO ka rutile titanium dioxide wale nō ka helu heheʻe a me ka helu paila. ʻO ka helu hoʻoheheʻe o rutile titanium dioxide he 1850 ° C, ʻo ka helu hoʻoheheʻe ʻana i ka ea he (1830 ± 15) ° C, a ʻo ka helu hoʻoheheʻe ʻana i ka oxygen-waiwai he 1879 ° C. ʻO ka helu heheʻe e pili ana i ka maʻemaʻe o ka titanium dioxide. . He (3200 ± 300)°C ka paila paila o ka rutile titanium dioxide, a he maalea iki ka titanium dioxide i keia wela wela.
3) Dielectric mau
Loaʻa i ka Titanium dioxide nā waiwai uila ma muli o kona mau dielectric kiʻekiʻe. Ke hoʻoholo nei i kekahi mau waiwai kino o ka titanium dioxide, pono e noʻonoʻo ʻia ke kuhikuhi crystallographic o nā kristal titanium dioxide. He haʻahaʻa haʻahaʻa ka dielectric mau o anatase titanium dioxide, 48 wale nō.
4) Ka hoʻokō
Loaʻa i ka Titanium dioxide nā waiwai semiconductor, piʻi wikiwiki kona conductivity me ka mahana, a ua maʻalahi hoʻi ia i ka nele o ka oxygen. ʻO ka dielectric mau a me nā waiwai semiconductor o rutile titanium dioxide he mea nui loa ia i ka ʻoihana uila, a hiki ke hoʻohana ʻia kēia mau waiwai e hana i nā mea uila e like me nā capacitors ceramic.
5) Paʻakikī
E like me ka paʻakikī o Mohs, ʻo ka rutile titanium dioxide he 6-6.5, a ʻo ka anatase titanium dioxide he 5.5-6.0. No laila, i ka pau ʻana o ka fiber kemika, hoʻohana ʻia ke ʻano anatase e pale aku i ka ʻaʻahu o nā lua spinneret.
6) Hygroscopicity
ʻOiai he hydrophilic ka titanium dioxide, ʻaʻole ikaika loa kona hygroscopicity, a ʻoi aku ka liʻiliʻi o ke ʻano rutile ma mua o ke ʻano anatase. He pilina ko ka hygroscopicity o ka titanium dioxide me ka nui o kona ili. ʻO ka ʻili nui a me ka hygroscopicity kiʻekiʻe e pili pū ana i ka mālama ʻana i ka ʻili a me nā waiwai.
7) Paʻa wela
ʻO ka Titanium dioxide kahi mea me ke kūpaʻa wela maikaʻi.
8) ʻO Granularity
ʻO ka hāʻawi ʻana i ka nui o ka titanium dioxide he kikoʻī kikoʻī, e pili nui ana i ka hana o ka titanium dioxide pigments a me ka hana noi huahana. No laila, hiki ke nānā pono ʻia ke kūkākūkā e pili ana i ka uhi ʻana i ka mana a me ka dispersibility mai ka puʻunaue ʻana o ka nui o nā ʻāpana.
He paʻakikī nā mea e pili ana i ka puʻunaue nui o ka titanium dioxide. ʻO ka mua ka nui o ka nui o ka nui o ka hydrolysis. Ma ka hoʻoponopono ʻana a me ka hoʻoponopono ʻana i nā kūlana kaʻina hana hydrolysis, ʻo ka nui o ka ʻāpana kumu i loko o kahi kikoʻī. ʻO ka lua ka mahana calcination. I ka wā o ka calcination o ka metatitanic acid, loaʻa nā ʻāpana i kahi manawa hoʻololi aniani a me kahi wā ulu, a mālama ʻia ka mahana kūpono e hana i nā ʻāpana ulu i loko o kahi ākea. ʻO ka hana hope loa ka pulverization o ka huahana. ʻO ka maʻamau, hoʻohana ʻia ka hoʻololi ʻana o ka mill Raymond a me ka hoʻoponopono ʻana i ka wikiwiki analyser e hoʻomalu i ka maikaʻi pulverization. I ka manawa like, hiki ke hoʻohana ʻia nā mea hana pulverizing ʻē aʻe, e like me: pulverizer kiʻekiʻe, pulverizer jet a me nā wili hāmare.
