Abrasive Walnut in shell 150 mesh for glass polishing 

 

 

Description:

 

Walnut shell is developed and produced to lightweight filter material aiming at oily sewage treatment.

Raw material is based on superior quality thick pecan shell, produced through degreasing, crushing,

polishing, thermophilic digesting and many times screening. It is yellowish-brown, not decay, without

spot, and has high tenacity.  

 

Application:

 

Walnut shell is used as an abrasive blast media similar to sand for cleaning, but without the negativities

 associated with other abrasive materials. In many typical cleaning applications the substrate is metal,

 fiberglass, wood, plastic or stone. Walnut shell can be utilized without scratching or pitting the substrate

 material / underlying surface. The walnut shell is ground to various sizes from coarse to extra fine depen

ding the application.

 

Property :

1. High hardness, wear resistance, and good pressure resistance. 
2. Easy to dissolve in acid and alkali solution. 
3. Strong adsorption and dirt-cutting ability. Its adsorption rate is 27-50%. 
4. Good hydrophilic, resistant to oil immersed. 
5. Easy to backwashing and regeneration. It can be directly used for backwashing before filtering. 
6. Low operation cost, and easy to manage.
