Изобретение относитс  к получению кле  из сухих гипсовых смесей, используемого дл  устройства перегородок из плит с любой конфигурацией соединени .The invention relates to the production of dry gypsum glue mixtures used for the installation of slab partitions with any joint configuration.

Целью изобретени   вл етс  повышение жизнеспособности, водо- и морозостойкости .The aim of the invention is to increase the viability, water and frost resistance.

Дл  приготовлени  сухой смеси в качестве гипсового в жущего используют о -полугидрат из фосфогипса Воскресенского ПО Минудобрени  и - полугидрат Новомосковского гипсового комбината, в качестве замедлител  твердени  - триполифосфат натри . Дл  повышени  водоудерживающей способности клеевого состава используютFor the preparation of a dry mixture, the o-hemihydrate of phosphogypsum of the Resurrection ON of the Fertilizer and the Novomoskovsk gypsum combine hemihydrate are used as a gypsum in a binder, and sodium tripolyphosphate as a retarder. To increase the water retention capacity of the adhesive composition is used

технический казеин и твердые лигно- сульфонаты марки Т.technical casein and solid T. brand lignosulfonates

Сухую смесь дл  кле  готов т смешением предварительно отдозированных сухих компонентов состава путем помола в шаровой мельнице в течение 15-20 мин.The dry glue mix is prepared by mixing the pre-dosed dry ingredients of the composition by grinding in a ball mill for 15-20 minutes.

Приготовленную сухую гипсовую смесь затвор ют водой при водогип- совом отношении 0,6. После 10-15 мин вьщержки клей приобретает рабочую консистенцию.The prepared dry gypsum mix is shut off with water at a water – gypsum ratio of 0.6. After 10-15 minutes of delivery, the glue acquires a working texture.

Составы кле , приготовленные из сухих гипсовых смесей, приведены в табл.1, а их основные технические свойства - в табл.2.The compositions of glue prepared from dry gypsum mixes are given in table 1, and their main technical properties are given in table 2.

Как видно из табл.2, сочетание выбранных компонентов сухих гипсовых смесей позвол ет повысить жизнеспособность кле  в 4-10 раз, при этом адгезионные показатели кле  на гипсо бетонной подложке улучшаютс  в сравнении с прототипом в 1,5-2 раза. Однако у составов 1 и Г наблюдаетс  снижение растекаемости, а у составов 5 и 5 происходит заметное увеличени растекаемости кле  на подложке, что ухудшает их технологичность. Формула изобретени As can be seen from Table 2, the combination of the selected components of dry gypsum mixtures makes it possible to increase the viability of the adhesive by 4-10 times, while the adhesive characteristics of the gypsum adhesive to the concrete substrate are improved in comparison with the prototype by 1.5-2 times. However, in formulations 1 and G, a decrease in flowability is observed, and in formulations 5 and 5, there is a noticeable increase in the flowability of the adhesive on the substrate, which impairs their processability.
