Kini titanium oloro?
Ẹya akọkọ ti titanium dioxide jẹ TIO2, eyiti o jẹ pigmenti kẹmika ti ko ni nkan pataki ni irisi funfun tabi lulú. Kii ṣe majele, ni funfun giga ati imọlẹ, ati pe a gba pe awọ funfun ti o dara julọ fun imudarasi ohun elo funfun. O ti wa ni lilo pupọ ni awọn ile-iṣẹ bii awọn aṣọ, awọn pilasitik, roba, iwe, inki, awọn ohun elo amọ, gilasi, ati bẹbẹ lọ.

Ⅰ.Titanium dioxide pq aworan atọka:
(1(Iwọn oke ti pq ile-iṣẹ oloro titanium ni awọn ohun elo aise, pẹlu ilmenite, ifọkansi titanium, rutile, ati bẹbẹ lọ;
(2) Aarin ṣiṣan n tọka si awọn ọja titanium oloro.
(3) Isalẹ jẹ aaye ohun elo ti titanium oloro.Titanium dioxide jẹ lilo pupọ ni awọn aaye oriṣiriṣi bii awọn aṣọ, awọn pilasitik, ṣiṣe iwe, inki, roba, ati bẹbẹ lọ.

Ilana kirisita ti titanium oloro :
Titanium dioxide jẹ iru agbopọ polymorphous, eyiti o ni awọn fọọmu gara mẹta ti o wọpọ ni iseda, eyun anatase, rutile ati brookite.
Mejeeji rutile ati anatase jẹ ti eto kirisita tetragonal, eyiti o jẹ iduroṣinṣin labẹ iwọn otutu deede; brookite jẹ ti eto kirisita orthorhombic, pẹlu eto kristal riru, nitorinaa o ni iye iwulo diẹ ninu ile-iṣẹ lọwọlọwọ.

Lara awọn ẹya mẹta, alakoso rutile jẹ ọkan ti o ni iduroṣinṣin julọ. Ipele Anatase yoo yipada laisi iyipada si ipo rutile loke 900 ° C, lakoko ti alakoso brookite yoo yipada ni aiṣe-pada si ipo rutile loke 650°C.
(1) titanium oloro alakoso rutile
Ni rutile alakoso titanium oloro, Ti awọn ọta wa ni aarin ti awọn kirisita lattice, ati mẹfa atẹgun awọn ọta wa ni be ni awọn igun ti titanium-oxygen octahedron. Octahedron kọọkan jẹ asopọ si awọn octahedrons 10 agbegbe (pẹlu awọn inaro pinpin mẹjọ ati awọn egbegbe pinpin meji), ati awọn ohun elo TiO2 meji ṣe apẹrẹ sẹẹli kan.

Ọna asopọ ti titanium oxide octahedron (ọtun)
(2)Anatase alakoso titanium oloro
Ni ipele titanium oloro anatase, titanium-oxygen octahedron kọọkan ni asopọ si 8 octahedrons agbegbe (awọn egbegbe pinpin 4 ati awọn igun pinpin 4), ati awọn moleku TiO2 4 ṣe apẹrẹ sẹẹli kan.

Ⅲ.Awọn ọna Igbaradi ti Titanium Dioxide:
Ilana iṣelọpọ ti titanium oloro ni akọkọ pẹlu ilana sulfuric acid ati ilana chlorination.

(1) Ilana Sulfuric acid
Ilana imi-ọjọ sulfuric ti iṣelọpọ titanium oloro pẹlu ifaseyin acidolysis ti irin titanium irin lulú pẹlu sulfuric acid ogidi lati ṣe agbejade imi-ọjọ titanium, eyiti o jẹ hydrolyzed lẹhinna lati ṣe agbejade acid metatitanic. Lẹhin calcination ati fifun pa, awọn ọja titanium oloro ti gba. Ọna yii le ṣe agbejade anatase ati rutile titanium dioxide.
(2) Ilana chlorination
Ilana chlorination ti iṣelọpọ oloro oloro titanium pẹlu dapọ rutile tabi lulú slag titanium giga pẹlu coke ati lẹhinna gbejade chlorination otutu otutu lati ṣe agbejade tetrachloride titanium. Lẹhin ifoyina iwọn otutu ti o ga, ọja titanium oloro ni a gba nipasẹ sisẹ, fifọ omi, gbigbe, ati fifun pa. Ilana chlorination ti iṣelọpọ oloro oloro titanium le ṣe awọn ọja rutile nikan.
Bii o ṣe le ṣe iyatọ ododo ti titanium dioxide?
I. Awọn ọna Ti ara:
(1)Ọna ti o rọrun julọ ni lati ṣe afiwe ifarakanra nipasẹ ifọwọkan. Iro titanium oloro rilara dan, nigba ti onigbagbo titanium oloro rilara rougher.

II. Awọn ọna kemikali:
(1) Ti a ba fi lulú kalisiomu kun: Fifi hydrochloric acid yoo fa ifarahan ti o lagbara pẹlu ohun ti n pariwo, ti o tẹle pẹlu iṣelọpọ nọmba nla ti awọn nyoju (nitori pe kaboneti kalisiomu ṣe atunṣe pẹlu acid lati gbejade carbon dioxide).
![微信图片_202405301437546](http://www.sunbangtio2.com/uploads/微信图片_202405301437546.png)
(2) Ti a ba fi lithopone kun: Ṣafikun sulfuric acid dilute tabi hydrochloric acid yoo mu õrùn ẹyin ti o bajẹ.

III. Awọn ọna ti o dara meji tun wa:
(1) Nipa lilo agbekalẹ kanna ti PP + 30% GF + 5% PP-G-MAH + 0.5% titanium dioxide lulú, agbara isalẹ ti awọn ohun elo ti o ni abajade jẹ, diẹ sii ni otitọ titanium dioxide (rutile) jẹ.
(2) Yan resini sihin, gẹgẹbi ABS ti o ni itara pẹlu 0.5% titanium dioxide lulú ti a fi kun. Ṣe iwọn gbigbe ina rẹ. Isalẹ gbigbe ina jẹ, diẹ sii ni ododo ti lulú oloro titanium jẹ.
