Abstract
Description
Изобретение относится к области изготовления защитных покрытий стальных труб, используемых в частности к теплосетях. The invention relates to the field of manufacture of protective coatings for steel pipes used in particular for heating systems.
Известна мелкозернистая смесь, включающая мас.%: портландцемент М400 35,7; песок 52,3; жидкое стекло 0,34; винилацетат 0,34; суперпластификатор С-3 0,34; воду остальное (RU 2091344, 1997). Known fine-grained mixture, including wt.%: Portland cement M400 35.7; sand 52.3; water glass 0.34; vinyl acetate 0.34; superplasticizer C-3 0.34; the rest of the water (RU 2091344, 1997).
Недостатком данной смеси является низкая стойкость к воздействию изменяющейся температуры теплоносителя до 150oС.The disadvantage of this mixture is the low resistance to changing temperatures of the coolant up to 150 o C.
Задачей изобретения является устранение данного недостатка за счет более рационального подбора гранулометрического состава и соотношения компонентов смеси для обеспечения близких значений коэффициентов температурного расширения. The objective of the invention is to eliminate this drawback due to a more rational selection of particle size distribution and the ratio of the components of the mixture to ensure close values of the coefficients of thermal expansion.
Технический результат достигается тем, что мелкозернистая смесь для антикоррозионного покрытия внутренней поверхности труб, включающая вяжущее, песок, воду и добавки, в качестве вяжущего содержит цементную композицию, а в качестве добавки - водный раствор суперпластификатора С-3 и сахарной патоки при следующем соотношении компонентов, мас,%:
Цементная композиция
Вяжущее низкой водопотребности ВНВ-100 - 22,3 - 18,2
Вяжущее низкой водопотребности ВНВ-70 - 13,4 - 10,9
Портландцемент М400 ДО - 8,47 - 6,9
Суперпластификатор С-3 - 0,03 - 0,028
Сахарная патока - 0,22 - 0,072
Песок - 44,6 - 54,7
Вода - 10,98 - 9,2
Свойства предлагаемой смеси в сопоставлении с прототипом приведены в таблице.The technical result is achieved in that a fine-grained mixture for anticorrosive coating of the inner surface of pipes, including a binder, sand, water and additives, contains a cement composition as a binder, and an aqueous solution of S-3 superplasticizer and molasses as an additive in the following ratio of components, wt%:
Cement composition
The binder of low water demand VNV-100 - 22.3 - 18.2
The binder of low water demand VNV-70 - 13.4 - 10.9
Portland cement M400 DO - 8.47 - 6.9
Superplasticizer C-3 - 0.03 - 0.028
Sugar syrup - 0.22 - 0.072
Sand - 44.6 - 54.7
Water - 10.98 - 9.2
The properties of the proposed mixture in comparison with the prototype are shown in the table.
Предлагаемую смесь приготавливают в смесителях принудительного перемешивания. При нанесении ее на внутренюю поверхность труб целесообразно использовать метод центрифугирования и торкретирования. The proposed mixture is prepared in mixers forced mixing. When applying it to the inner surface of the pipes, it is advisable to use the method of centrifugation and shotcrete.
Использование изобретения позволяет повысить стойкость смеси к воздействию изменяющейся температуры теплоносителя до 150oCтThe use of the invention improves the resistance of the mixture to the effects of changing temperature of the coolant up to 150 o
