1、 What is the difference between sponge sandpaper and regular sandpaper

Sponge sandpaper is a type of sandpaper. Compared to ordinary sandpaper, sponge sandpaper is not made of paper or cloth as an abrasive carrier, but is made of sponge and abrasive. The main difference between sponge sandpaper and ordinary sandpaper is that it is ground on the sponge. In addition, the differences between the two are:


1. Generally, sandpaper is often used to polish rough surfaces, while sponge sandpaper is more suitable for surface grinding.


2. Generally, sandpaper is in the form of sheets, while sponge sandpaper can be made into various shapes and standards.


3. General sandpaper is usually dry ground, while sponge sandpaper can absorb water and has good water resistance. It can be ground dry or wet.


4. The service life of sponge sandpaper is usually longer than that of general sandpaper of the same standard.

2、 Can sponge sandpaper replace sandpaper

With the invention and development of sponge sandpaper, more and more occasions have begun to use sponge sandpaper. Can sponge sandpaper replace sandpaper?


Sponge sandpaper, like ordinary paper sandpaper, has a layer of sand planted on the paper and another layer of sand planted on the sponge. It can be said that sponge sandpaper is an advanced product of ordinary sandpaper. Relatively speaking, sponge sandpaper is more durable, softer, and has a better draft than ordinary sandpaper. Moreover, because sandpaper is made of sponge, it has a very good pressure sensation and evenly distributed force during polishing, Although the polishing efficiency is similar to that of regular paper sandpaper, it feels better when polishing than paper sandpaper, and sponge sandpaper of the same thickness is more evenly polished than regular sandpaper.


Therefore, in summary, sponge sandpaper is better than regular sandpaper and can replace regular sandpaper. However, sponge sandpaper has a higher cost compared to regular sandpaper. Therefore, it is mainly used for craft polishing of furniture, surface polishing of plastic products, polishing of car repair paint areas, surface treatment of metal rust spots and plastic, and other areas with high polishing requirements. Generally, sandpaper is more economical and cost-effective for polishing.
