Description

Насто щее предложение относитс  к приборам дл  поддержани  посто нной температуры проб искусственных смол во врем  определени  скорости их полимеризации .The present proposal relates to instruments for maintaining a constant temperature of artificial resin samples during the determination of their polymerization rate.

На чертеже фиг. 1 изображает вид прибора сбоку с частичным разрезом и фиг. 2-вид прибора сверху.In FIG. 1 is a side view of the device with a partial section; and FIG. 2-view of the device from the top.

Прибор представл ет собой цилиндр 1, изготовленный из железа,к которому плотно привинчена крышка 2. На крышке выточено цилиндрическое углубление 4 дл  испытуемой смолы и отверстие 5 дл  помещени  термометра. В самом цилиндре сделано отверстие 6 дл  вывода трубки 3, соединенной с обратным холодильником.The device is a cylinder 1 made of iron, to which the lid 2 is tightly screwed. A cylindrical recess 4 for the test resin and a hole 5 for placing the thermometer are machined on the lid. A hole 6 is made in the cylinder itself to lead out a tube 3 connected to a reflux condenser.

Прибор нагреваетс  на любом источнике тепла и в него загружено посто нно кнп щсе, не разлагающеес  при температуре .кипени  вещество. Когда жидкость кипит, ее пары омывают нижнюю поверхность крыщки 2 и, так как парыThe device heats up on any heat source and is constantly loaded into it, which does not decompose at a boiling point. When the liquid boils, its vapors wash the bottom surface of the lid 2 and, since the vapors

имеют всегда строго посто нную температуру , а теплоизлучение и радиаци  при одинаковых услови х-величины также посто нные, то крыщка во всех точках углублени  4 будет иметь одинаковую температуру.always have a strictly constant temperature, and the radiation and radiation under the same conditions, the magnitude is also constant, then the lid at all points of the recess 4 will have the same temperature.

В- углубление 4 помещаетс  испытуема  смола и хронометром отсчитываетс  врем  перехода от стадии А, через В, до С (неплавкой).B-depression 4 is placed on the test resin and the transition time from stage A, through B, to C (non-melting) is counted by a chronometer.

Предмет изобретени .The subject matter of the invention.

Прибор дл  поддержани  посто нной температуры проб искусственных смол во врем  определени  скорости их полимеризации , отличающийс  тем, что в крышке 2 железного цилиндра 1 с жидкостью, имеющгй посто нную тем пературу кипени , выточено углубление 4 дл  помещени  испытуемой пробы при температуре, определ емой температурой кипени  жидкости. к авторскому свидетельству 1Г. М. Козлова Л 36692A device for maintaining a constant temperature of artificial resin samples during the determination of their polymerization rate, characterized in that the lid 2 of an iron cylinder 1 with a liquid having a constant boiling temperature is machined with a recess 4 for placing the test sample at the temperature determined by fluid. to copyright certificate 1G.
