In the realm of industrial and laboratory equipment, the choice of material for the outer shell of polishing machines plays a crucial role in determining the long - term stability, durability, and safety of the equipment. There is a common misconception among many that stainless steel is the most durable material for the outer shell of polishing machines. However, this might not always be the case.
Let's break down the performance parameters of three common materials: plastic, stainless steel, and fiberglass - reinforced plastic (FRP). We'll compare them in terms of acid - alkali resistance time, wear - resistance index, and maintenance frequency.
| Material | Acid - Alkali Resistance Time | Wear - Resistance Index | Maintenance Frequency |
|---|---|---|---|
| Plastic | About 1 - 2 years in mild acid - alkali environment | Low (easily scratched) | High (frequent replacement may be needed) |
| Stainless Steel | 3 - 5 years in general acid - alkali environment | Medium | Medium |
| FRP | Over 5 years in harsh acid - alkali environment | High | Low |
From the above table, we can see that FRP has significant advantages in terms of acid - alkali resistance and wear - resistance, which means it can better withstand the test of time in harsh environments.
Let's take a look at some real - world examples. A well - known industrial laboratory in the chemical industry has been using polishing machines with FRP shells. According to their feedback, in an environment where they frequently come into contact with acid and alkali reagents and are exposed to high - dust conditions, the FRP - shelled polishing machines have a much lower failure rate compared to those with plastic or stainless - steel shells. Third - party test reports also show that FRP can significantly extend the service life of the equipment in complex working conditions.
"Since we switched to the Jincheng P - 2T double - disc manual polishing machine with a high - strength FRP shell, which is specially designed for harsh environments, we've noticed a significant reduction in equipment failures. It has greatly improved our sample preparation efficiency." - A satisfied customer
To ensure the long - term performance of FRP - shelled polishing machines, here are some daily maintenance suggestions:
