Kodi Titanium Dioxide ndi chiyani?
Gawo lalikulu la Titanium dioxide ndi TiIO2, yomwe ndi utoto wofunikira wa inroric mu mawonekedwe a cholimba kapena ufa. Sikuti ndi poizoni, imakhala yoyera kwambiri komanso yowala, ndipo imawerengedwa kuti khungu loyera labwino kwambiri la kulemera. Amagwiritsidwa ntchito kwambiri m'mafakitale monga zokutira, mapulasitiki, pepala, pepala, inki, galasi, gramics, etc.
Ⅰ.Titanium Dioxide Fayilo Check:
(1) Kukweza kwa Titanium dioxide dlowero timakhala ndi zopangira, kuphatikiza ismentite, titanium ng'anjor, etile, ndi zina;
(2) Midgerm imatanthawuza zinthu za Titanium dioxide.
(3) Kutsikira ndi gawo la ntchito Titanium dioxide.Titanium Dioxide imagwiritsidwa ntchito kwambiri m'minda yosiyanasiyana monga zokutira, mapulagiti, pepala, inki, etc, etc.
Ⅱ.
Titanium dioxide ndi mtundu wa polymousphous pawiri, yomwe ili ndi mitundu itatu yodziwika bwino mwachilengedwe, yomwe ili ndi matundu atatu achilengedwe mu chilengedwe, omwe ali ndi vuto la matchalitchi, omwe ndiatate, okhwima ndi Brookite.
Onse awiri a Rutule ndi Anatase ndi a Crystal Shorstal, womwe uli wokhazikika pansi kutentha wamba; Brookite ndi ya ma kristal shortal shortal, yokhala ndi kristal yosakhazikika, chifukwa chake ilibe phindu pakugulitsa pakadali pano.
Mwa zina zitatuzo, gawo la Runile ndi lokhazikika. Gawo la Anatase lisasinthidwe kuti liziyenda bwino pamwamba pa 900 ° C, pomwe gawo la Brookite lisasinthidwe kukhala gawo la Rutile Pamwamba 650 ° C G.
(1) Gawo la Rutule Titium Dioxide
M'magawo a Crudule DIATHID DIOXID TIOXID TIMODZI YA Crystal, ndi ma atomu asanu ndi limodzi a ocygen amapezeka m'makona a Titanium-octagen. Octahedroni iliyonse imalumikizidwa ndi octadroni ozungulira (kuphatikizapo ma vertios asanu ndi atatu ogawana), ndi mamolekyu awiri a Tio2 amapanga selo ya unit.

(2) Anatase phase Tinium Dioxide
Ku Anatase PESE Titanium dioxide, chilichonse cha titanium - ocygen octahedron ozungulira (4 akugawana mabowo), ndi mamolekyu 4 a TiO2 amapanga selo ya unit.

Njira za Titanium Dioxide:
Kupanga kwa Titanium dioxide makamaka kumaphatikizapo kusintha kwa sulfuric acid ndi njira yolembera.
(1) sulfuric acid ndondomeko
Njira ya sulfuric acid ya kupanga Titanium Dioxide ya acidium ya inning ndi sulfuric ad acid, yomwe imapangidwa kuti ipange metatithanic acid. Pambuyo kuwerengedwa ndi kuphwanya, zinthu za catanium dioxide zimapezeka. Njirayi imatha kupanga anatose ndi Rutule Titanium dioxide.
(2) Njira ya chlorinan
Njira yopangira titanium dioxide ya Titaniium imaphatikizapo kusakaniza rutle kapena kwambiri-titanium slag ufa ndi coke kenako ndikugwira chlorinad chlorin tetrachloride. Pambuyo pa oxidation kwambiri, mafuta a Titanium dioxide amapezeka kudzera mu kusefedwa, kutsuka madzi, kuyanika, ndi kuphwanya. Njira yopangira titanium dioxium imangotulutsa zinthu zopingasa zokha.
Kodi mungasiyanitse bwanji tanthauzo la Titanium Dioxide?
I. Njira zakuthupi:
(1)Njira yosavuta kwambiri ndikufanizira mawonekedwe ndi kukhudza. Zabodza za titanium dioxide kumva bwino, ngakhale titanium daoxide ya Tioxide imamva bwino.
(2)Pakukatula ndi madzi, ngati mungayike tiinium dioxide pa dzanja lanu, zabodza ndizosavuta kuchapa, pomwe weniweni siophweka kuchapa.
(3)Tengani chikho cha madzi oyera ndikutsitsa titanium dioxide mu izo. Yemwe amayandama pamwamba ndi weniweni, pomwe amene akukhazikitsa pansi ndi wabodza (njirayi silingagwire ntchito zoyendetsedwa kapena zosinthidwa).
(4)Onani kusungunuka kwake m'madzi. Nthawi zambiri, titanium dioxide imasungunuka m'madzi (kupatula kwa titanium daoxide dayoxide yopangidwa mwachindunji kwa ma pulasitiki, inks, ndi zina zopangidwa ndi titanium daoxide, yomwe ili yopanda madzi).
Ii. Njira zamankhwala:
.
.
. Komabe, mutaziziritsa ndi ethanol kenako ndikuwonjezera hydrochloric acid, ngati thovu limapangidwa, zimatsimikizira kuti chitsanzo chili ndi calcium calbonate ufa wa carbonate.
Iii. Palinso njira zina ziwiri zabwino:
.
. Yerekezerani mawonekedwe ake opepuka. Kuchepetsa kuwala ndi, zenizeni ufa wa Titanium dioxium ndi.
