Description
Предметом изобретени вл етс способ получени сухой гипсовой штукатурки из порошкообразного гипса и йаполнителей, укладываемых в форму в сухом виде, с последующим увлажненисМ.The subject of the invention is a method for producing dry gypsum plaster from powdered gypsum and honey fillers laid in a mold in a dry form, followed by wetting.
Отличительна особенность предлагаемого способа состоит в том, что увлажнение гипса производитс путем прососа воды, подаваемой в необходимом количестве сверху издели , дл чего с противоположной стороны издели создаетс разрежение.A distinctive feature of the proposed method is that the gypsum is moistened by pumping water supplied in the required amount from the top of the product, for which a vacuum is created on the opposite side of the product.
На фиг. 1 изображена установка дл изготовлени сухой гипсовой штукатурки дл осуществлени описываемого способа; на фиг. 2-то же, в поперечном разрезе.FIG. Figure 1 shows a plant for making dry gypsum plaster for carrying out the described method; in fig. 2 is the same in cross section.
Сущность предлагаемого способа заключаетс в том, что гипсовую смесь 2, состо щую из гипсового порошка с добавлением 5-10% олилок (по весу), закладывают в форму 1 на мешковину 3, уложенную на решетчатое днище 4 и разравнивают гладилкой 5 до намеченной толщины- Слой гипса закрывают мешковиной и прижимают крышкой 6, в которой имеютс отверсти . На крышку 6 наливаетс вода (60-70% от веса смеси) и через патрубок 7 подключаетс вакуум (пор дка 20- 50 мм).The essence of the proposed method lies in the fact that the gypsum mixture 2, consisting of gypsum powder with the addition of 5-10% olilok (by weight), is laid in form 1 on sackcloth 3, laid on trellised bottom 4 and smoothed with a leveling pad 5 to the intended thickness. A layer of gypsum is closed with sacking and pressed against the lid 6, in which there are holes. Water is poured on the lid 6 (60-70% by weight of the mixture) and a vacuum is connected through the nozzle 7 (on the order of 20-50 mm).
Отсос воды продолжаетс 3-4 мин., после чего вакуум отключаетс , избыток воды сливаетс через патрубок 8, и снимаетс крышка 6.The suction of water continues for 3-4 minutes, after which the vacuum is turned off, the excess water is drained through the pipe 8, and the cover 6 is removed.
Схватившеес изделие вынимаетс из формы (выталкиваетс или вырезаетс нолсом), после чего с него снимаетс мещконина, вл юща с посто нным фильтром дл формы.The griped product is removed from the mold (pushed out or cut out by the knot), after which the mesherconin, which is a permanent filter for the mold, is removed.
Листы гипсовой штукатурки, полученные описываемым способом, при выемке из формы содержат 15-20% воды и имеют (в высушенном состо нии) временное сопротивление изгибу кг/см.The sheets of gypsum plaster obtained by the described method, when removed from the mold, contain 15-20% water and have (in the dried state) a temporary flexural strength of kg / cm.
