    Temperature Deviation ≤2.0 °c Salt Spray Test Box Composite Type Testing Machine


    Compound salt spray test machine series


    product description:


    The cyclic corrosion test is a more realistic salt spray test than conventional constant state exposure. Because actual outdoor exposure usually involves both dry and wet environments, it is meaningful to speed up the laboratory to simulate these natural, periodic conditions. Studies have shown that after cyclic corrosion testing, the relative corrosion rate, structure, morphology and outdoor corrosion results of the samples are very similar. Therefore, the cyclic corrosion test is closer to real outdoor exposure than the traditional salt spray method. They can effectively evaluate many corrosion mechanisms such as general corrosion, galvanic corrosion and crevice corrosion.


    The purpose of the cyclic corrosion test is to reproduce the type of corrosion in an outdoor corrosive environment. The test exposes the sample to a series of different conditions in a circulating environment. A simple exposure cycle, such as the Prohesion test, exposes the sample to a cycle consisting of salt spray and dry conditions. More complex automotive testing methods require a cycle of humidity and rest, in addition to salt spray and drying cycles. Initially these test cycles were performed manually, and the laboratory operator moved the sample from the salt spray chamber to the wet test chamber and then to a dry or stand-up unit. Microprocessor-controlled test chambers automate these test steps, reducing test uncertainty.

    According to GB, ISO, IEC, ASTM, JIS standards, the spray test conditions can be set and meet: GB/T 20854-2007, ISO14993-2001, GB/T5170.8-2008, GJB150.11A-2009, GB/ T2424.17-2008, GBT2423.18-2000, GB/T2423.3-2006, GB/T 3423-4-2008.

    Introduction to the work process:


    Spray process for cyclic corrosion testing:


    The salt spray system consists of a solvent tank, a pneumatic system, a water tank, a spray tower, a nozzle, etc., and the brine is transported from the water storage tank to the test chamber by the Bernotte principle. The spray nozzle and the heat pipe work to provide the required humidity and temperature in the tank. The salt solution is atomized by compressed air by spraying.

    The temperature inside the box is raised to the specified requirements through the bottom heating rod. After the temperature is stable, the spray switch is turned on. At this time, the salt spray test is performed. Compared with the ordinary salt spray test machine, the temperature in the test chamber is heated by the heating rod. While ensuring temperature uniformity, the effect of water vapor on the test results of the ordinary salt spray test machine is minimized.

    The movable spray tower is designed for easy removal and maintenance, and the use of the test space is more flexible and convenient.


    The salt spray test system has the following characteristics:


    1. Control instrument: The controller adopts Korea imported "TEMI-880" 16-bit true color touch screen, the program group is 120 groups, and the total number of cycles is 1200 times.


    2. Temperature sensor: anti-corrosion platinum resistance PT100Ω/MV


    3, heating method: using titanium alloy high-speed heating electric heater, multi-point layout, stable uniformity


    4, spray system: tower spray system, high-grade quartz nozzle, no work for a long time, no uniform distribution of fog particles


    5, salt liquid collection: in line with the national standard funnel and standard metering cylinder, the settlement can be adjusted and controlled


    6, two-pole intake decompression, to ensure the spray gas


    The damp heat process of the cyclic corrosion test:


    The humidity system consists of a water steam generator, a blast, a water circuit, a condensing device, etc. After the salt spray test, the machine will set up a defogging process to discharge the salt spray of the salt spray test to the test room as soon as possible; then the water evaporator will root The temperature and humidity set by the controller are suitable for temperature and humidity output. Generally, the humidity is relatively accurately calibrated and constant after the temperature is stabilized.


    The instrument humidifier system has the following features:


    Micro-motion humidification system using electronic parallel mode


    The humidifying cylinder is made of whole PVC and is corrosion resistant.


    Evaporator coil dew point humidity (ADP) laminar flow contact dehumidification


    With double protection device for overheating and overflow


    Water level control uses mechanical float ball valve to prevent electronic malfunction


    The wet water adopts an automatic water supply system, which is suitable for continuous and stable operation of the machine for a long time.


    Resting and drying process:


    The static and drying system adds drying blowers, heating wires, air filters and other devices to the damp heat system. For example, it is required to simulate a standard atmospheric pressure environment test: temperature 23 ° C ± 2 ° C, humidity 45% ~ 55% RH, first The damp heat test of the previous paragraph is quickly removed by setting a defogging process to create a relatively clean test environment, and then the humidifier or dehumidification system is coordinated under the controller to produce an environment that meets the test requirements.


    Test conditions:


    Spray test conditions can be set:


    A. Salt spray test: NSS * Laboratory: 35 °C ± 2 °C * Saturated air tank: 47 °C ± 2 °C


    B, damp heat test:


    1, test temperature range: 35 ° C - 60 ° C.


    2, test humidity range: 80% RH ~ 98% RH can be adjusted.


    C. Rest test:


    1, test temperature range: 20 ° C - 40 ° C


    2, test humidity range: 35% RH-60% RH ± 3%.


    Use materials:

    1. Enclosure shell material: imported 8mm grade A PVC reinforced hard board, the surface is smooth and flat, and resistant to aging and corrosion;


    2. Liner material: 8mm Class A corrosion-resistant PVC board.


    3. Cover material: The cover is made of 8mm grade A corrosion-resistant PVC sheet, with two transparent observation windows. The cover and the box are made of special foam sealing ring to prevent salt spray from leaking out. The tip angle is 110° to 120°.


    4, heating for multi-point air heating, heating up quickly, temperature distribution is even.


    5, three-dimensional observable reagent supplement tank, you can observe the salt consumption at any time.


    6. The well-designed water storage and water exchange system ensures smooth and reliable operation of the waterway.
