Description
Изобретение относитс к области технологии строительных материалов, а именно к составам дл замедлени схватьюа- ни гипсовых и цементных растворных смесей.The invention relates to the field of building materials technology, namely to compositions for retarding the scooping of gypsum and cement mortar mixes.
Известен замедлитель схватьгаани минеральных в жущих, включающий натриевую соль сополимера салициловой кислоты с формальдегидом и воду ij .A known inhibitor of skvvatgani mineral in the food, including the sodium salt of a copolymer of salicylic acid with formaldehyde and water ij.
Известный замедлитель схватывани требует строгой дозировки препарата, так как превышение его оптимального количества приводит к пониженной прочности в проектные сроки.The known retarder requires a strict dosage of the drug, since exceeding its optimal amount leads to a reduced strength in the design period.
Наиболее близким к изобретению по технической сущности и достигаемому результату вл етс замедлитель схватьшани , включающий поваренную соль, щелочь и воду. Кроме того известный замедлитель схватывани содержит и сульфитноспиртовую бражку 2. Однако такой замедлитель не обеспечивает длительное сохранение подвижности растворных сме- сей. Кроме того, прочностные показатели :строительных изделий при использованииClosest to the invention in technical essence and the achieved result is a skhvatshan retarder, including table salt, alkali and water. In addition, the known setting retarder also contains a sulfite alcohol brew 2. However, such a retarder does not ensure the long-term preservation of the mobility of the mortar mixtures. In addition, strength indicators: building products when using
известного замедлител несколько снижаютс .the known retarder is somewhat reduced.
Целью изобретени вл етс повьииение подвижности и сохранени прочностных показателей растворных смесей.The aim of the invention is to increase mobility and preserve the strength characteristics of mortar mixes.
Это достигаетс тем, что замедлитель схватывани гипсовых и цементных в жущих , преимущественно дл растворных смесей, включающий хлористый натрий, щелочь и воду, содержит дополнительно кубовые остатки производства карбокси- метилцеллюлозы при следующем соотношении компонентов, вес.%:This is achieved by the fact that the retarder of setting gypsum and cement in the cement, mainly for mortar mixes, including sodium chloride, alkali and water, contains addition bottoms of carboxymethylcellulose in the following ratio of components, wt.%:

Технологи введени предлагаемого замедлител схватьгоанг сводитс к тому/ что поступающий с завода-изготовител замедлитель схватывани (препарат КО-1),The introduction technology of the proposed skvvagoang retarder is reduced to the fact that the retarder coming from the manufacturer (setting KO-1),
имеющий плотность 1,1-1,13 г/см, вводитс в растворную смесь с водой аатво-i рени в количестве 5-10% от массы гипсовбго или цементного в жущего.having a density of 1.1-1.13 g / cm, it is introduced into the solution mixture with ato-i water of rhenium in an amount of 5-10% by weight of gypsum or cement cement.
Примерные составы замедлител схватывани приведены в табл. 1. В табл. 2 приведены свойства получен- ее Exemplary retarder formulations are given in Table. 1. In table. 2 shows the properties obtained

Как видно из таблицы, введение замедлител схватывани увеличивает нача . ло схватывани с 2 час, 25 мин. до 6 час. 5 мин.As can be seen from the table, the introduction of a setting retarder increases the beginning. Lo seized from 2 hours, 25 minutes. till 6 o'clock 5 minutes.
Замедлитель схватьюани сохран ет подвижность смеси до 56 минут, повыша The scavenger retardant retains the mobility of the mixture for up to 56 minutes, increasing
