Product Description
The rubber and plastic low temperature brittleness tester is used to measure the highest temperature of rubber and plastic samples when they are damaged by impact under specified conditions, that is, the brittle temperature. It can make comparative identification of the performance of non-hard plastics and other elastic materials under low temperature conditions, and the advantages and disadvantages of temperature and low temperature performance. Therefore, it is indispensable in scientific research materials and production process control. This instrument is designed according to GB/T15256 and GB/T5470 national standards, and is the latest developed compressor refrigeration equipment. This equipment adopts cascade compressor refrigeration technology, uses the principle of heat balance and circulating stirring method to achieve automatic uniform cooling and constant temperature of the sample.
1. This equipment consists of the main body of the refrigeration compressor, a heating device, an electronic control box, a cooling tank, a cooling medium circulation system, an automatic alarm device and other parts. After the refrigeration switch is turned on, the compressor starts working and the refrigeration system enters the formal working state. The refrigeration compressor works continuously. When it approaches the set temperature, the heating device in the cooling tank begins to provide heat in proportion to balance the excess cold generated by the refrigeration system to achieve the purpose of constant temperature. Stirring can make the cooling medium in the cooling tank circulate continuously to make the temperature uniform.
2. Sample holder
Rubber: A sample can hold up to 5 at a time, generally not more than 4;
Plastic: A sample can hold 15 at a time, and B sample can hold 5 at a time.
3. Impact device
The impact device consists of an impact hammer and a self-locking mechanism.
4. Impactor
4.1 Rubber
a) The radius of the impact head is 1.6±0.1mm;
b) During impact, the gap between the impact head and the sample holder is 6.4±0.3mm;
c) The distance between the center line of the impact head and the sample holder is 8±0.3mm.
4.2 Plastic
4.2.1 Sample A:
a) The radius of the punch is 1.6±0.1mm;
b) The radius of the jaws is 4.0±0.1mm;
c) The gap between the center line of the punch and the fixture is 3.6±0.1mm;
d) The gap between the outer side of the punch and the fixture is 2.0±0.1mm
4.2.2 Sample B:
a) The radius of the punch is 1.6±0.1mm;
b) The gap between the center line of the punch and the fixture is 7.87±0.25mm;
c) The gap between the outer side of the punch and the fixture is 6.35±0.25mm
1. Specifications:
1.1 Rubber
The length of the sample is 25.0±0.5mm, the width is 6.0±1mm, and the thickness is 2.0±0.2mm.
1.2 Plastic
A: The length of the sample is 20.0±0.25mm, the width is 2.5±0.1mm, and the thickness is 2.0±0.1mm.
B: The length of the sample is 31.75±6.35mm, the width is 6.35±0.51mm, and the thickness is 1.91±0.13mm
2. Requirements
The surface of the sample should be smooth, free of foreign matter and damage. The finished product should be molded or polished and cut to the corresponding size.
| Temperature control range | -70ºC (room temperature ≤ 25ºC) (there are three models of -60, -70, -80ºC for customers to choose) |
| Cooling speed | 0ºC ~ -20ºC 1.2ºC/min -20ºC ~ -30ºC 1.0ºC/min -30ºC ~ -60ºC 0.7ºC/min -40ºC ~ -60ºC about 0.7ºC/min -60ºC ~ -70ºC about 0.5ºC/min Note: The operating environment is used at room temperature (23-25ºC).
