Description
(54) ЗАМЕДЛИТЕЛЬ СРОКОВ СХВАТЫВАНИЯ ГИПСА(54) DEADLINES FOR PLUGGLING
Изобретение относитс к составам замедлителей сроков схватывани в жущих веществ и может быть использовано в промышленности строительных материалов . Известен нзвестково-клеевой замедлитель схватывани гипса l. Недостатком вл етс мала подвижность строительных растворов с добавкой клеевого замедлител . Наиболее близким по технической сутцности и достигаемому результату вл етс замедлитель сроков схватывани гипса сульфитно-дрожжева бракка (С ДБ) 2. Применение СДБ повышает подвижность гнпсового теста. Однако зaмeдлs ющa способность СДБ не достаточна дл укладтш гипсовых раст воров. Целью насто щего изобретени - вл етс устранение указанных недостатков и удлинение сроков схватывашш гипса. Указанна цепь достигаетс тем, что замедлитель сроков схьаты&анил. гипса, ючающий СДБ , дополнительно содергашеную известь, при следующем тношении компонентов, вес .ч: Сульфитно-дрожжева бражка2-10 Известь гашена 1-6 Пример. Дл получени замедел приготавливают несколько смесей; ержащие кажда , вес.ч.: 1)Высушенный порошок СДБ2 гашеной извести6 2)Высушё нный порощок СДБ5 гашеной извести4 3)Высушенный порошок СДБ10 гашеной извести1 4) Высушенный По .роиюк СДБ10 гашеной извести6 Каждую смесь отдельно заливают О вес .4. воды. Полученной суспензией вор ют 100О,О вес.ч. гипса.The invention relates to compositions of retarding time setting in earthing substances and can be used in the building materials industry. Known well-adhesive retardant seizure of gypsum l. The disadvantage is the low mobility of mortars with the addition of an adhesive retarder. The closest in technical value and the achieved result is a time delay setting of gypsum sulphite-yeast defective gypsum (C DB) 2. The use of BDB increases the mobility of the gnpsum dough. However, the substitute capacity of the SDB is not sufficient for placing gypsum plants. The purpose of the present invention is to eliminate these drawbacks and lengthen the time for setting gypsum. This chain is achieved in that the time delayer is skated & anil. gypsum, yuchuyuschiy SDB, additionally containing lime, with the following treatment of components, weight. h: Sulphite-yeast mash 2-10 Lime is slaked 1-6 Example. Several mixtures are prepared to produce a retarder; Each of them is harvested by weight, including: 1) Dried lime powder SDB2 hydrated lime6 2) Dried powder SDB5 hydrated lime 4 3) Dried powder SDB10 hydrated lime 4 4) Dried Allowed Hydrated lime SDB10 hydrated lime6 Each mixture was poured separately. water. The suspension obtained is thrown 100 O, O weight.h. gypsum.
Замед иггели испытывают на врем схватывани и имеют следующие пока .зателн: l) 7 мин; 2) 22 мин; З) 28 мин; 4) 90 мин.Sluggish iggels are tested for setting time and have the following results: l) 7 min; 2) 22 min; H) 28 min; 4) 90 min.
Кроме того, с дополнительным введением извести в СДБ снижаетс водопотребность гипсового теста дл достижени нормальной консистеншш (120 ммIn addition, with the addition of lime to the RRM, the water requirement of the gypsum dough is reduced to achieve normal consistency (120 mm
