Description
Изобретение относитс к .титейному про- и;1В()дству, в частности к литью по выплавл емым и посто нным модел м, и может быть использовано при шликерном литье керамических изделий.The invention relates to .protect pro- and; 1B (), this, in particular, to casting on produced and permanent models, and can be used in slip casting of ceramic products.
Целью изобретени вл етс повышение точности и упрощение проведени измерений .The aim of the invention is to improve the accuracy and simplify the measurement.
На чертеже представлено предлагаемое устройство.The drawing shows the proposed device.
Устройство состоит из измерительного узла в виде эластичной полой сферы 1, мембраны 2, тензорезисторов 3, патрубка 4, источника 5 питани и регистрирующего прибора 6. Мембрапа 2 закреплепа на корпусе 7 и взаимосв зана с патрубком 4 и сферой I каналами 8. Испытуемое покрытие 9 наноситс на сферу 1.The device consists of a measuring unit in the form of an elastic hollow sphere 1, membrane 2, strain gauges 3, pipe 4, power source 5 and recording device 6. The membrane 2 is fixed to housing 7 and interconnected with pipe 4 and sphere I with channels 8. Test coating 9 applied to sphere 1.
Устройство работает следующим обра:i )M.The device works as follows: i) M.
Через патрубок 4 по каналам 8 в измерительный узел закачиваетс определенное к().1ичество воздуха. Затем на эластичнуюThrough pipe 4 through channels 8, the amount of air defined to () is pumped into the measuring unit. Then on elastic
сферу I наноситс испытуемое влажное керамическое покрытие 9. По мере сушки, в результате усадки покрыти , сжимающие напр жени деформируют сферу 1, умень- П1а ее объем. Возникающее фи этом избыточное давление выгибает мембрану 2. В результате деформации мембрань соответственно измен етс сопротивление и ток в тензорезисторах 3 и пропорпиопально току мен етс показание на регистрирующем приборе 6. Калибровка прибора 6 позвол ет непосредственно производить измерение напр жений в любой момент времени. Кроме того, измер етс объемна усадка керамического покрыти , как разница показаний прибора в начальный и заданный момент времени. По записи сигнала на прибор 6 от тензо- резисторс в 3 во времени суд т о кинетике изменени усадочных напр жений.sphere I applies the test wet ceramic coating 9. As the coating shrinks and shrinks, the compressive stresses deform sphere 1, reducing its volume. The resulting overpressure arises in this way flexing the membrane 2. As a result of the deformation of the membrane, the resistance and current in the strain gauges 3 change accordingly and the reading on the recording device 6 changes proportionally to the current. Calibration of the device 6 allows direct measurement of voltages at any time. In addition, the volume shrinkage of the ceramic coating is measured as the difference in the readings of the instrument at the initial and predetermined point in time. By recording the signal to the device 6 from a strain resistor at 3 in time, the kinetics of the change of shrinkage voltages is judged.
Предлагаемое устройство предназначено дл использовани в услови х предпри ти дл контрол процесса усадки покрытий при сушке и определени ее оптимальных режимов .The proposed device is intended to be used under the conditions of an enterprise to control the process of shrinking of coatings during drying and to determine its optimal modes.
