Analysis of Common Pathological Phenomena of Roadside Stones

Many people notice various spots and blemishes on the surface of curb stones. Many find this appearance quite pleasing, but unaware that if such phenomena spread, it can affect our use of curb stones, impacting their value and lifespan. This kind of phenomenon is referred to as a pathological change.

Common types of defects in curbstone mainly include the following.

The most common defect in curbstone manufacturers is rust spots. The key to preventing rust is to apply effective surface treatment after curbstone processing to prevent the oxidation of iron minerals from渗出 to the surface. Generally, an oil-based protective agent is used. When dealing with rust spots, we typically use rust removers, but many contain acidic or alkaline substances that can erode the internal structure of the curbstone. Therefore, special attention must be paid when selecting rust removers for curbstone.

The phenomenon of discoloration is water spots and damp stains. Preventing water spots mainly involves injecting resin to make curb stones waterproof, thereby blocking the contact between moisture in the air and the internal substances of the curb stones or cement, reducing the conditions for chemical reactions.
