JL-1 building material combustion calorific value tester
Introduction: JL-1 type building material combustion calorific value tester, also known as building material product combustion calorific value tester, building material combustion calorific value calorimeter, is to place a specific quality building material pattern in the test environment under standard conditions to test the type of combustion heat value. Under standard conditions, the test is based on the test temperature and the heating value of the model is calculated taking into account all heat losses and latent heat of vaporization. JL-1 type building material combustion calorific value tester meets the technical indexes and requirements specified in GB/T14402-2007 "Determination of Combustion Heat Value of Building Materials and Products", and is applicable to the test of building material combustion calorific value. . Its equivalent standard is: ISO1716-2002 The test method specified in this standard is used to test the absolute calorific value of the combustion of the test article, regardless of the form of the product. Features: 1. Microcomputer automatic control, 2. Compact structure, beautiful appearance, easy installation and maintenance, and low failure rate. 3. Small size, a large number of molds are used, and the precision is high. 4. The repeatability and reproducibility of the heat test of building materials is better than the requirements of GB/T14402-2007. 5. High degree of automation, automatic use of the amount of water in the built-in container, Technical Parameters: Power supply voltage: AC220V ± 10% 50Hz; Maximum operating power: 0.5KW; Ambient temperature: (10 ~ 35) ° C, humidity ≤ 80%; Instrument heat capacity: about 10000J/K; Heat capacity repeatability error: ≤0.2%; Temperature range: (4.5-42) °C; Temperature resolution: 0.0001K; Heat capacity stability <0.2% Precision <0.1% Oxygen bomb volume: 300ml; Inner cylinder volume: 2000ml; Oxygen bomb sealing: oxygenation pressure 2.5 ~ 3.5MPa, no air leakage; Oxygen bomb pressure resistance: 20MPa water pressure; Stirring power: 3W; Stirring speed: inner cylinder (375r/min); Standard material for measurement: benzoic acid powder.
