Изобретение относитс  к промышлен НОС .ТИ строительных материалов и может быть использовано в производстве изделий из  чеистого бетона.The invention relates to the industrial sphere of technical materials. Building materials and can be used in the manufacture of cellular concrete products.

Известен способ контрол  и регулировани  процесса вибровспучивани   чеистой смеси путем измерени  интенсивнос т-й газовыделени .There is a method of controlling and regulating the process of vibration of the cell mixture by measuring the intensity of the gas emission.

Недостатком такого способа  вл етс  необходимость установлени  преобразователей электропроводности и температуры во вспучивающейс  смеси, что св зано со сложностью их фиксации и последующего извлечени  из отформованной смеси. Кроме того, при извлечении преобразователей повреждаетс  изделие. По известному способу не учитываетс  газовыделение с поверхности смеси.The disadvantage of this method is the need to install transducers of electrical conductivity and temperature in the intumescent mixture, which is associated with the difficulty of their fixation and subsequent extraction from the molded mixture. In addition, when removing the transducers, the product is damaged. By a known method, gas evolution from the surface of the mixture is not taken into account.

Целью изобретени   вл етс  упрощение способа и повышение его точностиThe aim of the invention is to simplify the method and increase its accuracy.

Поставленна  цель достигаетс  TeMj что интенсивность газовыделени  измер ют с поверхности вспучивающейс  смеси.The goal is achieved by TeMj that the intensity of gas evolution is measured from the surface of the intumescent mixture.

Интенсивность газовыделени  с поверхности смеси измер ют поплавком, представл ющим собой перевернутый вверх дном стакан, плавучесть и герметичность которого с определенной осадкой обеспечиваетс  с помощью крыла, установленного по периметру поплавка. Выдел ющийс  из смеси газ, попада  под поплавок, выходит в атмосферу через измеритель количества газа.The intensity of gas evolution from the surface of the mixture is measured by a float, which is an upside-down cup, the buoyancy and tightness of which with a certain draft is provided by a wing installed along the perimeter of the float. The gas released from the mixture, released under the float, is released into the atmosphere through a gas quantity meter.

Поплавок в начале виброформовани  устанавливают на поверхности смеси, а по окончании вспучивани  снимают.At the beginning of vibro-forming, the float is placed on the surface of the mixture, and after the end of the swelling is removed.

В зависимости от скорости выделени  газа с поверхности смеси устанавливают необходимую интенсивность и про дол ительность вибраций.Depending on the rate of gas release from the surface of the mixture, the required intensity and duration of vibrations are set.

Процесс автоматического регулировани  осуществл етс  следующим образом.The process of automatic control is carried out as follows.

Смесь заливают в форму и включают диброустановку. От измерител  интенсивности газоввделени  на узел сравнени  передаютс  данные о выделении газа с поверхности смеси. Узел сравнени  сравнивает количество выдел ющегос  газа с заданной допустимой величиной задатчика, а результат сравнени  передаетс  на регулирующий орган, который, .воздейству  на виброустановку, измен ет интенсивность вибраций таким образом , чтобы поддерживать газовыделение с поверхности смеси в заданных пределах . Допустимые пределы газовыделени  установлены экспериментально и наход тс  в пределах 0,001-0,1 г/см . Воздействие вибраций прекращают в момент, когда при интенсивности вибрации, равной нулю, наблюдаетс  процесс газовыделани  через поверхность в количестве превышающем вышеуказанную норму газовыделени , что совпадает с моментом стабилизации вспучивани .The mixture is poured into the mold and turn on the dibunit. Data on the emission of gas from the surface of the mixture is transmitted from the gaseous intensity meter to the comparison unit. The comparison unit compares the amount of released gas with a predetermined allowable setpoint value, and the result of the comparison is transmitted to the regulator, which, on a vibrating unit, changes the intensity of vibrations in such a way as to maintain gas evolution from the surface of the mixture within specified limits. Allowable gassing limits are set experimentally and are in the range of 0.001-0.1 g / cm. The effect of vibrations is stopped at the moment when, at a vibration intensity equal to zero, the process of gas evolution through the surface is observed in an amount exceeding the aforementioned rate of gas evolution, which coincides with the moment of stabilization of swelling.
