摘要： PURPOSE:To enable the easy recovery of a volatile binder, by a method wherein a gas generated from the volatile binder is adhered and solidified on the surface of the base plate of a heat exchange arranged pipe in a cooling apparatus and the obtained condensate is recovered in a state dissolved in an org. solvent. CONSTITUTION:A volatile binder gas is introduced into a cooling apparatus 6 along with a N2 gas through an arranged pipe 5 and the former is adhered to and solidified on one surface of a base plate 8 having a heat exchange arranged pipe 7 fixed thereto cooled to 0 deg.C or less. On the other hand, an org. solvent in an org. solvent tank 9 is fallen onto the base plate 8 having the binder fixedly deposited and coagulated thereon from a nozzle 11 arranged to the upper part of the cooling apparatus 6 through a pump P and an arranged pipe 10 to dissolve the coagulated binder and discharged from the lower part of the cooling apparatus 6 as a binder liquid at a room temp. or less to be recovered in the org. solvent tank 9. As the result, the volatile binder can be easily recovered.

摘要： PURPOSE:To provide a vacuum heat treatment furnace which purifies a heat treatment atmosphere at high degrees by providing a panel which is cooled by a cryogenic refrigerant in the same space as that of a heat treatment chamber or the one communicating therewith. CONSTITUTION:A vacuum heat treatment chamber 2 is operated by maintaining the pressure therein at 1-760Torr by gaseous Ar or gaseous N2, and the surface temp. of a cryogenic panel 4 is controlled to 173-214 deg.K by a cooling gas 6. Namely, the H2O partial pressure and CWHV partial pressure in the atmosphere in the chamber 2 are controlled to 1X10 Torr (corresponding to 173 deg.K dew point)-1X10 Torr (corresponding to 214 deg.K dew point) irrespectively of the partial pressure in the chamber 2. As a result, the atmosphere necessary for oxidation-free heat treatment operation is easily obtained without flowing a large amount of high purity inert gas or reducing gas into the chamber 2 or without lowering the entire pressure of the atmosphere in the chamber 2 down to 5X10 Torr by the use of a large diameter oil diffusing pump. Here, 1 in the figure denotes the object to be treated, and 5 an agitating fan, respectively.
