Bgd 880-S Programmable Salt Spray Cabinets Programmable Salt Spray Corrosion Test Chamber

1.Description

Programmable Salt Spray(Fog)Cabinets is currently a widely used method to examine the corrosion resistance of coated metal substrates. It is suitable for rapid analysis of discontinuities, pores and damages that occur during application in organic and inorganic coatings. It is regarded as the most effective method for evaluating the properties of materials closely related to the Marine atmosphere, because it can simulate the basic conditions of certain accelerating effects caused by humidity or temperature, or both. Many special coatings (anti-corrosion coatings for steel structures/Marine coatings/automotive coatings and some coatings for heavy industry) clearly stipulate the number of hours of salt spray resistance tests that must be passed when formulating corresponding standards.
Biaogeda has many years of rich experience in the production of salt spray test chambers. All of our products are manufactured strictly in accordance with the national standard GB/T 1771 "Determination of Resistance to Neutral Salt Spray of Paints and varnishes" and the international standard ISO 7253 "Paints and varnishes - Determination of Resistance to Neutral Salt Spray". At present, more than thousands of Geda salt spray corrosion test chambers are in operation all over the world. The extremely low failure rate and good consistency have earned our products high recognition from customers.

*Test chamber material: The working chamber is made of imported 5mm thick PVC polyethylene board (Taiwan Nanya), with a thickness of 5mm and a durable temperature range of 85ºC.
*The sealing cover of the studio is made of imported European acrylic sheet with a thickness of 6mm.
*It is fabricated with a 100° Angle sealing cover at the top, effectively preventing condensation water from dripping onto the sample surface during the test and affecting the test results.
*In addition, the properties of this material ensure that the test chamber can not only perform neutral salt spray tests but also acidic salt spray (copper-accelerated acetic acid salt spray /CASS) tests.
*Spray liquid (salt water) tank: Made of PVC, it is hidden and has a liquid level monitoring port. It is easy to clean and not easy to break.
*Pressure air tank (saturation tank) : The SUS304# stainless steel high-pressure resistant tank has the best heat preservation effect.
* Sample rack: It adopts a planar dividing rack, which can be adjusted at any Angle for four-sided fogging and receiving, allowing for the placement of a large number of samples
*The sealing of the laboratory adopts a water sealing method to ensure that the corrosive gas inside the box does not leak
*The control box and the test chamber are integrated, with a left-right structure for convenient operation
*It adopts an isolation design for water and electricity components, effectively preventing water from entering the electrical control box and damaging the accessories
*Spray principle and route: It adopts Bernoult's principle to draw brine and then atomize it. Air compressor → Primary oil-water separator → Air storage tank → Pressure reducing valve → main solenoid valve → secondary oil-water separator → saturator → Pressure regulating valve → Spray solenoid valve → Nozzle
*Spray tower: To ensure the uniformity and volume of the spray, air atomizing nozzles are used to finely atomize the salt water, which then enters the conical spray tower and is evenly distributed into the test space.
*The height of the spray tower can be adjusted to achieve the purpose of precisely controlling the spray volume.
*The installation positions of the spray towers are evenly distributed at the bottom of the test area.
*Manual spraying can be set or automatic spraying can be set according to the program.
*Nozzle: Made of special glass material, it is anti-crystallization and can control the size and Angle of the spray volume
*Collector: The spray volume collector (a conical funnel with a diameter of 100mm and an area of 80cm ²) is installed in the working chamber to monitor the spray volume in real time.
*A silicone hose is installed at the bottom of the funnel and connected to the outdoor graduated cylinder, allowing for real-time viewing of the spray volume and ensuring the accuracy of the test samples
*Heating system: Titanium alloy armored electric heating tube (heating at the bottom of the test chamber); SUS316# stainless steel armored heating tube (saturation bucket) Steam heating method, with heating capacity controlled by P.I.D; Heating tube control mode: SSR (solid State relay) contactless periodic pulse width modulation
*Salt spray liquid supply system: The prepared salt spray solution is stored in the salt water tank and supplied to the salt water supply container through the water level difference. This supply container can automatically control the upper limit of the water level by setting the water level control switch valve to maintain the distance from the nozzle.
* Air saturation bucket: SUS304 stainless steel, adjustable working temperature RT to 63ºC; The heating time is ≤60 minutes. It can achieve automatic water replenishment and has the functions of liquid level monitoring and liquid level limit alarm.
Temperature controller: Japanese Omron E5CC digital display, controlling the temperature of the laboratory and the saturation bucket (display resolution 0.1ºC)
*Spray cycle program controller: Digital display, spray time and interval cycle can be set arbitrarily, infinite cycle; The timing units can be switched between seconds, minutes, ten hours, hours and ten hours. The maximum timing for each group is 999 hours and the minimum is 1 second
Protection function: Control circuit short-circuit protection fuse; Upper limit temperature alarm and over-temperature protection setter Heater anti-dry burning device, saturated air barrel heater anti-dry burning device, heater short circuit and overload protection; Laboratory water shortage protection and low water level protection for saturated air tanks
*Others: The total running time of the experiment can be set. After the experiment, manual defogging can be run or automatic defogging can be set according to the program
