Description
При работе со строительным гипсом быстрые сроки его схватывани создают неудобства при. производстве строительных работ, заставл готовить гипсовое тесто небольшими порци ми.When working with gypsum plaster, its quick setting time is inconvenient when. construction, forced to prepare gypsum dough in small portions.
При изготовлении же гипсовых форм быстрые сроки схватывани не дают возможности изготовл ть сложные и крупные гипсовые отливки .In the manufacture of gypsum forms, however, the quick setting time makes it impossible to manufacture complex and large gypsum castings.
Примен емые в таких случа х дл замедлени сроков схватывани гипса увеличенные добавки воды в большем количестве, чем это требуетс , значительно снижают прочность изделий.Used in such cases to slow down the time it takes for gypsum to set, the increased additions of water in larger quantities than is required significantly reduce the strength of the products.
Известно применение в качестве замедлителей схватывани стол рного кле , декстрина, а также таких отходов производства как сульфитно-спиртова или картофельна барда.It is known to use as retarders for the setting of table glue, dextrin, as well as such production wastes as sulphite-alcohol or potato bard.
По описываемому способу предлагаетс примен ть в качестве добавки в воду затворени строительного гипса отход спиртовых заводов-паточную барду в количестве от 0,05 до 0,3% от веса гипса, в пересчете на сухое вещество в барде.According to the described method, it is proposed to use as a additive to the water of mixing gypsum distillery waste distillery distillery grains in an amount of from 0.05 to 0.3% by weight of gypsum, calculated on the dry matter in bard.
Введение указанной добавки не только энергично замедл ет схватывание гипса, но и повышает механическую прочность изделийПредмет изобретени ,The introduction of this additive not only vigorously slows down the setting of gypsum, but also increases the mechanical strength of the products.
Способ улучшени свойств строительного гипса путем введени добавок в воду затворени , отличающийс тем, что, с целью замедлени сроков схватывани и повышени механической прочности, в качестве добавки примен ют паточную барду в количестве от 0,05 до 0,3% от веса гипса, в пересчете на сухое вещество в барде.A method for improving the properties of gypsum by adding additives to the mixing water, characterized in that, in order to slow down the setting time and increase the mechanical strength, a bard in an amount from 0.05 to 0.3% by weight of gypsum is used as an additive. in terms of dry matter in bard.
