I. Overview
PCY Plastic Coefficient of Thermal Expansion Tester is used for testing cryogenic expansion performance of solid inorganic, organic material, polymer, rubber or plastics.
Comply with ASTM D696, DIN53752, GB / T1036 "Plastics - Determination of linear expansion coefficient - quartz dilatometer Law". And GB / T2572 "plastic average linear expansion coefficient test method of fiber reinforced. The instrument can complete the sample linear variable, coefficient of linear expansion, coefficient of expansion volume, rapid thermal expansion and softening temperature curve.
II. Main technical parameters:
1, experimental temperature range: -40-200 ℃
2, computer program automatically sets the heating rate, temperature control accuracy 0.1 ℃, with a precision cooling - heating system.
3, computer software automatically calculates the coefficient of expansion, expansion coefficient of volume, coefficient of linear expansion and rapid thermal expansion.
4, automatic calculation and compensation coefficient, also can be manually corrected.
5, automatic recording, storage, printing, printing temperature - expansion coefficient curve.
temperature spacing set free, the minimum spacing 0.1-1 ℃.
6, the expansion measurement range: ± 5mm.
7, the expansion value resolution: 0.1-1um, automatic calibration range.
8, the size of the sample (2-15) × (2-15) × (20-150) mm, cylindrical / square all can be.
9, use imported linear bearing drive, to achieve expansion of value-free friction transmission, transmission accuracy and repeatability is excellent.
10, system measurement error: ± 0.1-0.5%.
11, power supply voltage: AC220V ± 10%, 0.5KW.
12, with a standard computer interface, all test operations are complete by computer software.
