Description
(54) СПОСОВ ПОЛУЧЕНИЯ СТАБИЛЬНОЙ ЗАРОДЫШЕВОЙ СУСПЕНЗИИ(54) WAYS OF OBTAINING STABLE EMERGENCY SUSPENSION
1зобретение относитс к TekHononiH получени двуокиси титана по сернокислотной схеме, преимушественно может быть использовано при Получении пиг- 5 ментной двуокиси титана рутильной модификации .The invention relates to TekHononiH for the preparation of titanium dioxide according to a sulfuric acid scheme, which can be mainly used for the preparation of pigmental titanium dioxide of rutile modification.
В современном производстве пигментной двуокиси титана рутильной модификации пЬодукт с высокими качественны- ю ми показател ми получают с использованием зародышевой суспензии - кислого , зол двуокиси титана 1,которкй ввод т в гидратированную двуокись титана перед ее прокалкой или в сер- д нокисльпй раствор титана на стадии его гидролиза 2 . Во всех случа х лучшими технологическими свойствг1ки обладает высокодисперсна стабильна зародышева суспензи , и более 20 высокое качество двуокиси титана достигаетс при введении ее на стадии гидролиза раствора. Дл предотвращени коагул ции и укрупнени частиц зародышевой суспензии обычно ее 25 стабилизируют органическими соединени ми . . , ,In modern production of pigmentary titanium dioxide, a rutile modification of the product with high quality indicators is obtained using a germ suspension - an acidic, titanium dioxide sol 1, which is introduced into hydrated titanium dioxide before calcining it or in a sulfur-doped titanium solution at the stage its hydrolysis 2. In all cases, the best technological properties of a highly dispersed, stable germinal suspension, and more than 20 high quality titanium dioxide is achieved with the introduction of it at the stage of solution hydrolysis. To prevent coagulation and coarsening of germ suspension particles, it is usually stabilized 25 with organic compounds. . ,,
Наиболее близким к описываемому изобретению по технической сущности и достигаемому результату вл етс . JQThe closest to the described invention to the technical essence and the achieved result is. Jq
.способ получени стабильной зародышевой суспензии путем введени в неё спиртов или водорастворимых полимеров в количестве 1-10 вес.% от содержани двуокиси титана 3.Однако при использовании зародышевой суспензии с таким содержанием органических стабилизаторов на стадий гидролиза сернокислого раствора титана происходит также стабилизаци части образующихс частиц гидратированной двуокиси титана. Эти стабилизированные частицы не удаетс выделит в осадок ни отстоем , так как они не осаждаютс , ни фильтрацией, так как они проход т через фильтрующий слой вместе с фильтратом. В результате потери двуокиси титана возрастают на 2-5%.A method of obtaining a stable germ suspension by introducing alcohols or water-soluble polymers into it in an amount of 1-10 wt.% based on titanium dioxide content 3. However, when using germinal suspension with this content of organic stabilizers, during the hydrolysis of titanium sulphate a solution also part of the resulting particles is stabilized hydrated titanium dioxide. These stabilized particles are not precipitated as precipitates, as they are not precipitated, or by filtration, as they pass through the filter bed with the filtrate. As a result, the loss of titanium dioxide increases by 2-5%.
Целью изобретени вл етс снижение потерь пигмента на стадии фильтрации гидратированной двуокиси титана . , The aim of the invention is to reduce pigment losses in the filtration phase of hydrated titanium dioxide. ,
Поставленна цель достигаетс описываемым способом получени стабильной зародышевой суспензии, включающим введение в кисльлй золь двуокиси титана добавки органического спирта триэтаноламина в смеси с гексаметаThe goal is achieved by the described method of obtaining a stable germ suspension, including the introduction into the acidic sol of titanium dioxide of an additive of organic alcohol triethanolamine in a mixture with hexamet
