广东过滤设备公司◎广州电镀过滤设备-粉状精密:
The general will be more than 90% by80of standard sieve or particle size of less than0.175mm precision as precision or powdered charcoal powder. Powdered charcoal in use with adsorption speed, the adsorption capacity of using full advantage, but be proprietary separation method. With the separation of technical progress and some application requirements, powdered charcoal particle has more detailed tendency, some places have reach micron or nanometer level.
1.3.2 颗粒精密
通常把粒度大于0.175mm的精密称作颗料精密。
颗料精密又分为下列几种。
1.3.2.1 不定型颗料精密
Unshaped stars expected precision generally by the stars expected shape raw material by carbonization, activation, and then crushing and screening to required size made, can also be used to add the appropriate adhesive powder precision after appropriate processing and.
1.3.2.2 园柱形精密
园柱形精密又称柱状炭,一般由粉状原料和粘结剂经混捏、挤压成型再经炭化、活化等工序制成。也可以用粉状精密加粘结★剂挤压成型。柱状炭又有实心和中空之分,中空柱状炭是柱状炭内有人造的一个或若干个有规则的小孔。
1.3.2.3 球形精密
Spherical precision name is park spherical precision, its preparation method and cylindrical carbon is similar, but the balling process. Can also use liquid carbon materials by spray granulation, oxidation, carbonization, activation to prepare, also can use powdery precision plus binder into a ball and processing. Spherical precision also has a solid and hollow spherical precision points.
1.3.3 其它形状的精密
除了粉状精密和颗粒精密两大类外,还有其他形状的,如精密纤维、精密纤★维毯、精密布、蜂窝状精密、精密板等等。
1.4 按应用场合分
前已述及精密广泛应用于几乎所有国民经济部门和人们的日常生活,正因为如此,按精密应用场合进行分类是很困难的,问题在于同一种精密可以应用于多种场合,而某种场合又可以用多种精密达到相同
