Overview
The ZHONGKEBODA BD/QL-225 ozone aging test chamber is a test device used to simulate and accelerate the aging process of materials in an ozone environment. The device has precise temperature and humidity control, ozone concentration adjustment, and static and dynamic tensile testing functions, suitable for evaluating the ozone aging performance of Non-metallic materials such as rubber and plastics.
Features
1. The box body is sprayed with A3 steel plate, and the studio is made of SUS304 stainless steel, which is beautiful and durable.
2, using high density fiberglass cotton insulation, equipped with long axis fan motor to achieve intensity convection circulation.
3. The door body adopts double-decked high temperature resistant sealing strip, and the observation window is multi-layer hollow tempered Glass to ensure airtightness and observation clarity.
4. Built-in 360-degree swirl/spin sample holder and swirl/spin sample fixture, support static and dynamic tensile testing.
5. The heating system adopts Far infrared nickel alloy high-speed heating electric heater, which is controlled by microcomputer calculation and has high accuracy.
6. The humidification system adopts a built-in boiler steam type, with automatic water level compensation and water shortage alarm functions.
7. The refrigeration system adopts a fully enclosed French Taikang Compressor, uses environmentally friendly refrigerants, and the system is independent and has undergone strict leak detection tests.
8, the control system adopts imported 7.0 inch touch screen, P.I.D microcomputer S.S.R controller, high accuracy and automatic calculation function.
9. The ozone system adopts a silent discharge tube generator, which is cooled down and equipped with imported British CT Electrochemical sensors for High Accuracy Testing.
10. Equipped with multiple safety protection systems, including over-temperature, under-phase/reverse-phase, overload, overvoltage, timing, and leakage protection.
Principle
The device generates ozone at a set concentration through an ozone generator and injects it into a test chamber with constant temperature and humidity. The specimen is mounted on a swirl/spin sample holder and can be tested for static stretching (fixed elongation) or dynamic stretching (cyclic stretching) according to the test requirements. Under the set temperature, humidity, ozone concentration and time conditions, the specimen is exposed to an ozone environment to accelerate its aging process, thereby evaluating the material's ozone-resistant checking performance.
Applications
Rubber, Plastic Products, Wire and cable, Coating coatings, Polymer materials and other Non-metallic materials ozone aging performance test
Standards
GB/T7762-2014 Static test method, GB/T13462-2015 Dynamic test method
Steps
1. Clamp both ends of the sample on a special fixture and set the required elongation (static test) or tensile frequency (dynamic test).
2. Fix the clamps for installing the samples on the swirl/spin sample holder inside the equipment.
3, through the touch screen control system to set the test required temperature, humidity, ozone concentration, test time and sample rack speed and other parameters.
4. Start the equipment, ozone generator, temperature and humidity control system, and sample holder to start running according to the set program.
5. After the test reaches the set time, the device automatically stops or issues a prompt.
6. Take out the sample, check and record its surface checking and other aging conditions.
Notice
Equipment operating environment should be below 28 ℃ and well ventilated.
• When the equipment is placed, 80 cm of space needs to be reserved for the front, rear, left and right, and items cannot be placed.
• Before use, please confirm that the power supply is AC380V +/- 10% 50Hz three-phase five-wire system.
• The humidification system needs to ensure that the water source is sufficient, and pay attention to the water shortage alarm prompt.
• During the operation of the equipment, do not open the door frequently to avoid affecting the Stability of the test conditions.
• Regularly check whether the safety protection function of the equipment is normal.
• When handling samples and maintaining equipment, follow relevant safety operating procedures.
