The temperature shock test chamber is used to test the material structure or composite material, and it can be tolerated in a continuous environment of high temperature and low temperature in an instant. It is suitable for use in scientific research, schools, factories, military and other units for electricians, electronic products, semiconductors, Adaptability tests of various materials such as electronic circuit boards, metal materials, and bearings in a temperature-changing environment.
1. Test purpose: To determine the adaptability and destructiveness of the test product when the ambient temperature changes rapidly.
2, test conditions: high temperature box: RT ~ 150 ° C, low temperature box: RT ~ -40 ° C, test temperature retention time: 1h or until the test sample reaches temperature stability, whichever is longer, the number of cycles: for different industries Different manufacturers have different test requirements and are tested according to the test methods on the standard.
3. Recovery: After the test product is taken out from the hot and cold impact box, it should be restored under normal test atmospheric conditions until the test sample reaches temperature stability.
4. Reference standard for high and low temperature impact test chamber:
GB/T2423.1.2, GB/T2423.2, GB10592, GJB150.3, GJB150.4
5. Requirements for temperature shock test chamber:
a. The thermal shock test is performed using a high temperature chamber and a low temperature chamber to provide an ambient temperature at which the test sample is subjected to abrupt changes in ambient air temperature.
b. The requirements of the high temperature zone shall comply with the requirements specified in the provisions of Chapter 3 of GJB150.3-86 "High Temperature Test for Environmental Test Methods for Military Equipment".
c. The requirements of the low temperature zone shall comply with the requirements specified in Articles 3 of GJB 150.4-86 "Cryogenic Tests for Environmental Test Methods for Military Equipment".
d. Provide the high temperature test section and the low temperature test section, which shall comply with the requirements specified in Articles 3 of GJB150.3-86 and GJB150.4-86, respectively.
e. The volume of the test chamber should be such that the test sample (room) temperature within the test sample (room) can reach the test condition tolerance specified in 3.2 of GJB150.1-89 when the test sample is placed in the candidate for more than 10% of the test temperature holding time.
6. Temperature shock test chamber control system:
The conversion time of low temperature zone and high temperature zone is ≤15s.
Temperature recovery time ≤ 5min.

For a variety of medical and knitwear
In civilian use, can be blended or purely woven into a variety of medical and knitwear. Nylon filaments are used in knitting and silk industry, such as weaving single stockings, elastic stockings and other wear-resistant nylon socks, nylon scarves, mosquito nets, nylon lace, elastic nylon coats, a variety of nylon silk or interwoven silk products. Nylon short fibers are mostly used to blend wool or other chemical fibers into wool-type products, making a variety of wear-resistant clothing materials.
In industry, nylon is used to make a large number of cords, industrial cloth, cables, conveyor belts, tents, fishing nets and so on. It is mainly used as parachute and other military fabrics in national defense.Polyamide is mainly used in synthetic fibers, its most prominent advantage is that wear resistance is higher than all other fibers, 10 times higher than cotton wear resistance, 20 times higher than wool, in mixed textiles slightly added some polyamide fiber, can greatly improve its wear resistance;
