Description
Изобретение касаетс способа Получени строительного гипса с заранее установленными показател МИ (в зависимости от назначени материала) путем введени различного рода добавок к высокопрочному гипсу.The invention relates to a method for obtaining gypsum with a predetermined MI index (depending on the purpose of the material) by introducing various kinds of additives to high-strength gypsum.
Заводы, производ щие высокоарочный гипс, могут при размоле гипса в мельнице или после помола вводить в него добавки такой же тонкости помола, как и сам гипс, при тщательном смешении.Plants that produce high-quality gypsum can, when grinding a gypsum in a mill or after grinding, add additives of the same fineness to it as the gypsum itself, with careful mixing.
При введении в высокопрочный гипс добавки в виде каменной муки активность гипса снижаетс в пр мом соответствии с увеличением водогипсового отнощени (В/г) при неизменной консистенции смеси. Это позБол ет раздел ть по маркам выпускаемый строительный гипс.When a stone flour additive is introduced into high-strength gypsum, gypsum activity decreases in direct accordance with an increase in water-gypsum ratio (V / g) with a constant mixture consistency. It possesses to break down the grades of manufactured building plaster.
Пример. Гипс высокопрочный марки «300 с водогипсовым отношением 0,4 и схватыванием: начало 7,5 мин., конец 11 мнн.Example. High-strength gypsum brand “300 with a water-gypsum ratio of 0.4 and setting: start 7.5 minutes, end 11 pl.
Мен дозировку добавки, можно получить гипс различных марок, напршмер , гипс марки с водогипсовым отношением 0,32 и схватыванием: начало 10 мин., конецMening the dosage of the additive, you can get various types of plaster, naprmer, brand of plaster with a water-gypsum ratio of 0.32 and setting: start 10 minutes, end
16 .мин. при составе 1 : 0,5 (гипс и каменна мука).16 minutes with a composition of 1: 0.5 (gypsum and stone flour).
Гипс марки «200 с водогипсовым отношением 0,30 и схватыванием: начало 12 мин. и конец 16 мин. при составе 1:1.“200” gypsum with a water gypsum ratio of 0.30 and setting: start 12 min. and the end of 16 min. with a 1: 1 composition.
Эти разновидности марки гипса могут быть использованы .дл различных назначений.These varieties of gypsum brand can be used for various purposes.
Некоторые марки относ.чтс к категории высокопрочных; они такл ;е улучшают свои свойства, благодар введению тонкомолотой камеи ной муки, и отвечают требовани м, предъ вл емым к материалам при изготовлении гипсовых деталей и изделий.Some brands relate to high strength category; they improve their properties due to the introduction of finely ground cameo meal, and meet the requirements of materials for the manufacture of gypsum parts and products.
При желании в качестве добавки может быть введен краситель, а также различные карбонатные горные породы.If desired, a colorant may be added as an additive, as well as various carbonate rocks.
Предмет изобретени Subject invention
Способ изготовлени строительного гипса, отличающийс тем, что высокопрочный гипс разбавл ют карбонатом кальци , например, известн ком , измельченным до степени размола гипса, в количестве от 30% и выше.A method of making gypsum, characterized in that high-strength gypsum is diluted with calcium carbonate, for example, lime, crushed to the degree of grinding gypsum, in an amount of 30% or more.
