Hot and cold cycle tester prohibited test items

The hot and cold cycle tester is able to tolerate the product under extremely low temperature and extremely low temperature in a continuous environment. It can detect chemical changes or physical damage caused by thermal expansion and contraction of the sample in a short time.

Hot and cold cycle testing machine prohibited test items (1), explosives:
1. Nitroglycol (ethylene glycol dinitrate), nitroglycerine (glycerol trinitrate), nitrocellulose and other explosive nitrates.
2. Trinitrobenzene, trinitrotoluene, trinitrophenol (picric acid) and other explosive nitro compounds.
3. Peracetic acid, methyl ethyl ketone peroxide, benzoyl peroxide and other organic peroxides.
(b) Combustibles:
1. Spontaneous Combustion: Metals: "Lithium", "Potassium", "Sodium", Yellow Phosphorous, Phosphorous Sulfide, Red Phosphorus. Celluloids: calcium carbide (calcium carbide), phosphatized lime, magnesium powder, aluminum powder, sodium bisulfite.
2. Oxide properties:
(1) Potassium chlorate, sodium chlorate, ammonium chlorate and other chlorates.
(2) Potassium peroxyate, sodium peroxyate, ammonium peroxoate, and other peroxyacid salts.
(3) Potassium peroxide, sodium peroxide, barium peroxate, and other inorganic peroxides.
(4) Potassium nitrate, sodium nitrate and other nitrates.
(5) Potassium hypochlorite and other hypochlorite.
(6) Sodium chlorite and other chlorites.
(III) Inflammables:
(1) Ether, gasoline, acetaldehyde, propylene oxide, carbon disulfide, and other substances that do not burn at -30°C.
(2) Normal ethane, ethylene oxide, acetone, benzene, methyl ethyl ketone, and other substances with a flash point above -30°C but less than 0°C.

Hydrogen, acetylene, ethylene, methane, ethane, propane, butane, and other gases that may combust at 1 atmosphere at 15°C.

Drum Brake Electric Tricycle cheaper, but also in line with traditional design. Tricycle car in the braking process, due to the role of inertia, the front wheel load usually accounts for 70% -80% of the total load of the tricycle, the front wheel braking force than the rear wheel, rear wheel auxiliary brake, so tricycle production Manufacturers in order to save costs, the brake on the front disc drum. High braking efficiency, complex structure, heavy weight, easy to implement hand brake. To slow down the moving parts, stop or keep the device stopped, can play a role in protecting traffic safety.
