Description

(54) СПОСОБ МОДИФИЦИРОВАНИЯ ПИГМЕНТНОЙ ДВУОКИСИ(54) METHOD FOR MODIFICATION OF PIGMENT DIOXIDE

tMTAHA При этом указанные карбоновые кислоты по данному способу берут с концент аиией , описанной вьпие. Предложенный способ позвол ет улучшить диспфгируемость до 10-15 ед, по клину и повысить атмосферостойкость пиг ментной двуокиси титана до 790-820ед. (измерение;по сильному мелению) по сра нению с известным способом, по котором пигмент получают с худшиМи показател ми , имеющими значени ,соответственно, пор дка 20-30 и 780. П р   м е р. 100 г пигментной двуокиси титана суспендируют в 1 л воды. К суспензии пигме 1та добавл ют 1,2 г Шюмйнйта натри  ЙаАЬО2.0,4 г силйката натрл  Мо(251Оз и 0,2 г фиэтаноламина И йопученную смесь далее нейтрализуют 1%-ньш раствором фталевой кислоты. Двуокисьтитана после указанной обработ ки oiitbiBakjiT от Водорастворимых , фильтруют и сушат при . Полученный ййгмеит имеет следующие ПйШентаые показатели} белизну 97%, разбеливающую способность 1985, фотохимическую активность 0,15, перетйраемость по клину 15, атмосффбстойкосУь до сильного мелени  820,3, сбдфжание ЕЮДорастворймых солей ПбСШ ЬдйоТ ратной присйлывки, не обнаружено. Йспбльзбванке предлагаемого изобретени  обеспечивает уменьшение расходаtMTAHA In this case, these carboxylic acids in this method are taken with the concentration described above. The proposed method allows to improve the dispersibility up to 10-15 units, along the wedge, and to increase the weatherability of titanium dioxide pigment dioxide to 790-820 units. (measurement; by strong chalking) in comparison with a known method, in which pigment is obtained with worse indicators having values, respectively, of the order of 20-30 and 780. Ex. 100 g of titanium dioxide pigment are suspended in 1 liter of water. 1.2 g of Sümünite sodium YaAbO2.0.4 g of sylkat sodium stromium Mo (251Oz and 0.2 g of fiethanolamine) are added to the suspension of the 1g pygmy suspension. The mixture is neutralized with a 1% solution of phthalic acid. The titanium dioxide after this treatment is oiitbiBakjiT from Vodor acid. , filtered, and dried at. The resulting yigmeite has the following PICENTIAL indices} whiteness 97%, bleaching ability, 1985, photochemical activity 0.15, permeability over wedge 15, atmospheric resistance to strong meleni 820.3, comparing with eHeating salts PbSSH, cdjing, 820.3, comparing with eHeating salts PbsHydler, ijing, 820.3, comparing with eHeating salts PbSH yd, yd, clearing 820.3, comparing with eHeating salts PbSH yd, yd, clearing 820.3, comparing with eHeating salts PbSH yd, yd, clearing 820.3; The inventive method of the invention provides a reduction in consumption
