Description
СПОСОБ ПОВЫШЕНИЯ ПРОЧНОСТИ METHOD OF IMPROVING STRENGTH
Известны способы повышени прочности силикатного кирпича путем введени добавок в сырьевую смесь.Methods are known for increasing the strength of silicate bricks by introducing additives into the raw mix.
С целью использовани отходов химической промышленности предложено в качестве добавок в сырьевую смесь вводить растворы нитрит-нитратов кальци 40%-пой концентрации в количестве 0,1-0,5% от веса сухой массы.In order to use the wastes of the chemical industry, it was proposed to introduce calcium nitrite-nitrate solutions of 40% concentration in an amount of 0.1-0.5% by weight of dry weight as additives to the raw mix.
Дл повышени прочности силикатного кирпича были использоваиы добавки растворов нитрит-нитратов кальци 40%-ной концентрации , получаемых при улавливании окислов азота па химических заводах известковым мо .локом. Растворы с этими добавками 1- 5%-ной концентрации были использованы вместо воды дл увлажнени сырьевой массы перед прессованием. Количество 40%-кого раствора солей, расходуемое на 1000 шт. кирпича (5,8 т сухой массы), колеблетс от 0,1 до 0,5%.To increase the strength of silicate bricks, additives of calcium nitrite-nitrate solutions of 40% concentration were used, which are obtained by trapping nitrogen oxides in chemical plants with a lime stone. Solutions with these additives of 1–5% concentration were used instead of water to moisten the raw mass before pressing. The amount of 40% solution of salts consumed in 1000 pcs. brick (5.8 tons dry weight), ranges from 0.1 to 0.5%.
При проведении лабораторных исследований было установлено, что прочность силикатного кирпича с добавками нитрит-нитратов кальци повышаетс на 17-29% в зависимости от количества добавки.In laboratory studies, it was found that the strength of silicate bricks with calcium nitrite-nitrate additives increased by 17-29%, depending on the amount of the additive.
Прочность кирпича в присутствии рассматриваемых добавок повышаетс за счет образовани при автоклавной обработке гидропитроалюмипатов кальци .The strength of the brick in the presence of the additives in question is increased due to the formation of calcium hydro-nitroaluminate during autoclave treatment.
Новизпа и принципиальное отличие предла гаемого способа повышени прочности сили катпого кирпича заключаетс в применениновых видов добавок - нитрит-нитратов, ЯЕ л ющихс отходами промышленности, которые способствуют образованию при автоклавной обработке химических соединений, придающих кирпичу повышенную механическую прочность.The novelty and the fundamental difference between the proposed method of increasing the strength of silica brick is the use of new types of additives - nitrite-nitrates, which are used in industry, which contribute to the formation of chemical compounds during autoclave processing, which give the brick increased mechanical strength.
