  • Method of determining thermal coefficient of materials
    Patent number: 5005985
    Abstract: A method for determination of the thermal conduction coefficient of a material sample comprises measurement of momentary temperature differences between two opposite surfaces of the material sample and measurement of heat supplied by a heater. Said material sample is placed in a system composed of the heater, two identical reference samples having known thermal conduction coefficient and two heat sinks. The material sample and the heater are sandwiched between the two heat sinks. All of them as so arranged are maintained in thermal contacts with each other. The measurements are made during a continuous linear change of the temperature of the two heat sinks.

  • Method of determination of thermal conduction coefficient and heat capacity of materials and the apparatus for measurements of thermal conduction coefficient and heat capacity of material
    Patent number: 4630938
    Abstract: A method and apparatus for determination the thermal conduction coefficient and the heat capacity of materials. The method comprises the measurements of heat flux across the sample and the momentary temperature difference between both surfaces of the sample perpendicular to the direction of heat flux during continuous change of the temperature of one of sample surfaces. The values of thermal conduction coefficient, heat capacity and thermal diffusivity are determined on the basis of an equation which defines their dependence on measured heat flux across the sample, temperature difference between the sample surfaces and the rate of the change of the temperature of one sample surface. The apparatus for measuring thermal conductivity and heat capacity contains a heater equipped with a temperature sensor of a thickness less than 1 mm, placed between two samples, one of them being the sample of material tested of a thickness less than 10 mm.

  • Process for improvement of adhesion between mineral fillers and thermoplastic polymers
    Patent number: 4411704
    Abstract: The method according to the invention is based upon that the mineral filler, before being mixed with thermoplastic polymer, is coated with a thin layer of liquid ethylene oxide oligomer, optionally in presence of a solvent and then the solvent is evaporated at temperature 50.degree. to 200.degree. C.By the method according to the invention, a product with much better useful properties is obtained. The product is useful in the plastics industry.
