Title: Hydraulic cement material setting retarding sheet
Inventor: ISHINO YOSHIAKI
IPC: C04B30/02
Filed: 1996-03-26
Abstract: PROBLEM TO BE SOLVED: To provide excellent water dispersibility without trouble such as clogging of a waste water treatment facility by incorporating setting retarder and water soluble polymer substance in water soluble base material constituted by papermaking water dispersible fiber and water soluble fibrous carboxylalkylcellulose salt. SOLUTION: The hydraulic cement material setting retarding sheet is obtained by incorporating setting retarder and water soluble polymer in water soluble base material constituted by papermaking water dispersible fiber and water soluble fibrous carboxyalkylcellulose salt. Thus, the setting of the surface of the hydraulic cement material molding curable material can be retarded, and can be easily dispersed and removed from the surface of a molding by an automatic washing machine by water injecting. Since the sheet is extremely rapidly dispersed to the size of no fault in a waste water treatment facility, the operating speed of the washing machine can be accelerated.

Filed: 1988-04-18
Abstract: PURPOSE:To cool down vapor for heating a low temperature generator to a saturation temperature to convert it into saturated vapor, to improve heat exchange performance, and to minimize the low temperature generator by spraying a refrigerant liquid condensed by a heat exchanger for heating within the low temperature generator through a sprayer. CONSTITUTION:Refrigerant vapor separated by a high temperature generator 1 passes through the inside of a cooling chamber 21 and is sent into a heat exchanger 23, and then, said refrigerant vapor is condensed by exchanging heat with an absorption liquid within a low temperature generator 3. A refrigerant liquid within the heat exchanger 23 flows, by its own weight, into a sprayer 22 provided at a lower position than the heat exchanger 23. The sprayer 22 sprays the refrigerant liquid to superheated vapor passing through the inside of the cooling chamber 21. A portion of the refrigerant liquid is evaporated by absorbing heat from the superheated vapor in its direct contact therewith. The temperature of the superheated vapor is lowered down to a saturation temperature by this evaporation of the refrigerant liquid or the spray thereof. The refrigerant liquid accumulated in the lower part of the cooling chamber 21 is pushed up through the inside of a tube 27 by the difference between the pressure in the cooling chamber 21 and that in a condenser 4 is fed into the condenser 4.
