产品详细说明:
核 桃 壳
核桃壳滤料采用优质山核桃壳为原料，经过破碎、抛光、蒸洗、药物防腐处理，两次筛选加工而成。此滤料坚韧、耐磨、抗压（抗压力为23.4kgf），化学性能稳定，吸附截污性强（吸附率为27-50％），抗油浸，易反洗再生，反冲洗强度低(6.7L/Sm2)，滤速快（24-26m/h），不板结，不腐烂，永不更换，每年只需补充5-10%即可。油去除率达95％，含油降至5mg/g以下。适用于油田、节油环保设备等方面。

一． [pore-forming materials] walnut shell particles
Our factory using foreign advanced technology specialized in vitrified bond grinding wheel hole porosity materials - walnut shell grains. Compared with the old pore-forming material-- refined naphthalene, our product has uniform pores, and it is odorless, non-polluting, easy to use, inexpensive and safe. Moreover, the pore size of the grinding wheel can be arbitrarily selected. Thus, in 60 years abroad, it has been widely adopted in abrasives industry.Physical and chemical performance indexBulk Density: 16 # - 36 # 0.85 ± 0.05g/cm46 # - 80 # 0.80 ± 0.05g/cmSize: 16 # - 36 # ，the screen overflow of 16# is 0, the screen underflow of 36# is no more than4%
