Over Temperature Protection ISO7253 PVC Rigid Plastic Board

Over-temperature protection ISO7253 PVC rigid plastic board Corrosion Test Chamber

Product Description:

Over-temperature protection ISO7253 PVC rigid plastic board Corrosion Test Chamber  is the use of salt spray corrosion way to detect corrosion, respectively, the reliability of the sample, salt spray refers to the atmosphere by diffusion system composed of tiny droplets of salt, artificial environment of three anti-series one of many companies need to simulate the destructive product of marine climate surrounding the product caused by salt spray chamber so the line should run. Salt spray test is divided into neutral and acidic salt spray two, the difference lies in the different standards and test methods to comply, respectively, said "NSS" and "CASS" test, three anti-artificial climate the most common test method

Do Test Method:

Neutral salt spray test (NSS test) salt spray test (SS test)
Acetic acid salt spray test (ASS test)
Copper accelerated vinegar instinct test

As a neutral salt spray test (NSS test), reinforced with PVC rigid plastic board when the salt spray test (SS test).
Using as acetic acid salt spray test (ASS test), copper accelerated vinegar instinct test (CASS test) when the PP plate.
Compared PP board PVC board and more resistant to corrosion at high temperatures.

Characteristics:

1. with low water level automatic charging function of the water level,
2. precision glass nozzle (PYREX) 4000 hours, with many no crystallization of obstruction of concern,
3. are in the same instrument control panel, simple operation, and can glance,
4. with dual over-temperature protection, water shortage warning to ensure safe use,
5. digital temperature display, SSR control accuracy of 0.1 ℃,
6. trough direct steam heating method, heating speed, shorten the standby time spray tower with conical diffuser, a guide fog adjust the amount of fog, and even off the fog and other functions.

Specification:

Standards:
CNS, 3627,3885,4159,7669,7670,8886,JIS,D020,H8302,H8610,K5400, Z2371,ISO,3768,3769,3770,ASTM,B117, B268

Precautions
1, regular cleaning and maintenance of salt spray chamber pressure tank, brine tank nozzle.
2. Do not pressure sodium chloride solution from the barrel manually add water poured out, the first transfer solution within the cylinder and then further cleaned with distilled water.
3, Do not test the exhaust pipe behind the blockage, in order to avoid too much pressure to make the cabinets housing deformation.
4, do not put inflammable and explosive materials inside.
5, salt spray chamber behind the pressure gauge is 2 kg, 1 kg in front, factory in Wuhan still test test Equipment Co., Ltd. has designed, do not tamper with.
6, spray amount is less than set the spray tower to increase, reduce excessive spray spray tower (spray amount collected standard is 1 ~ 2ml / h, takes in 16-hour average)
