廣東過濾設(shè)備公司◎廣州電鍍過濾設(shè)備-粉狀精密:
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 顆粒精密
通常把粒度大于0.175mm的精密稱作顆料精密。
顆料精密又分為下列幾種。
1.3.2.1 不定型顆料精密
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 園柱形精密
園柱形精密又稱柱狀炭,一般由粉狀原料和粘結(jié)劑經(jīng)混捏、擠壓成型再經(jīng)炭化、活化等工序制成。也可以用粉狀精密加粘結(jié)★劑擠壓成型。柱狀炭又有實心和中空之分,中空柱狀炭是柱狀炭內(nèi)有人造的一個或若干個有規(guī)則的小孔。
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 其它形狀的精密
除了粉狀精密和顆粒精密兩大類外,還有其他形狀的,如精密纖維、精密纖★維毯、精密布、蜂窩狀精密、精密板等等。
1.4 按應用場合分
前已述及精密廣泛應用于幾乎所有國民經(jīng)濟部門和人們的日常生活,正因為如此,按精密應用場合進行分類是很困難的,問題在于同一種精密可以應用于多種場合,而某種場合又可以用多種精密達到相同
