Project Record: Solving Rail Maintenance Pain Points with GRB-833 for Brake Valve Cleaning

In the maintenance of the braking systems of EMUs, subways and ordinary railways, the brake valve is a core safety component. However, traditional cleaning methods have always faced three major problems.

Case Details

Stubborn oil stains are hard to remove:
When silicone oil, silicone grease, rolling oil and carbon dirt are mixed, they will form stubborn oil stains in the valve body gaps and blind holes. Manual brushing can only clean the surface, and the residual hidden dangers in the inner cavity directly affect the braking accuracy.
Material compatibility risk:
The valve body is composed of various materials such as steel, copper, and aluminum. Strong acid and strong alkali cleaning agents can easily corrode the components, causing secondary damage.
Efficiency is in conflict with cleanliness:
When cleaning, either there is too much foam, making rinsing difficult, or the cleaning time is long, which is hard to match the fast-paced maintenance cycle.

How does GRB-833 achieve high efficiency and cleanliness?

1. This product is compounded from powerful emulsifiers, high-quality surfactants, cleaning AIDS, PH regulators, deionized water, etc., and contains no heavy metals

2. It has no corrosive effect on valve body materials such as steel, copper and aluminum, and can extend the service life of components

Core Advantage: Why Choose GRB-833?
1. It is used for quickly and effectively cleaning silicone oil, grease, oil stains and dirt on the surface of braking system components of EMUs, conventional railways, subways, maglev and other rail vehicles.

2. Low foam, anti-static, no residue after rinsing, and no water marks will be left on the surface of the workpiece.

3. The pressure for waste liquid treatment is low, which complies with the environmental protection and safety regulations of the rail transit industry
