本系列产品选用木屑为原料，采用化学法活化工艺生产，经后处理科学配方精制而成的高吸附性能粉状活性炭。
粉状活性炭产品介绍
木质粉状活性炭是一种黑色粉状，粒状或丸状的无定形具有多孔的碳，主要成分为碳，还含少量氧、氢、硫、氮、氯。也具有石墨那样的精细结构，只是晶粒较小，层层间不规则堆积。具有较大的表面积(500～1000米2/克)，有很强的吸附性能，能在它的表面上吸附气体、液体或胶态固体；对于气体、液体，吸附物质的质量可接近于活性炭本身的质量。其吸附作用具有选择性，在同一系列物质中，沸点越高的物质越容易被吸附，压强越大温度越低浓度越大，吸附量越大。反之，减压，升温有利于气体的解吸。常用于气体的吸附、分离和提纯，溶剂的回收，糖液、油脂、甘油、药物的脱色剂，饮用水及冰箱的除臭剂，防毒面具中的滤毒剂，还可用作催化剂或金属盐催化剂的载体。早期生产活性炭的原料为木材、硬果壳或兽骨，后来主要采用煤，经干馏、活化处理后得到活性碳生产方法有：①蒸汽、气体活化法。利用水蒸气或二氧化碳在850～900℃将碳活化。②化学活化法。利用活化剂放出的气体，或用活化剂浸渍原料，在高温处理后都可得到活性炭。
production process of powdered activated carbon
this series of products uses wood chips as raw materials, the chemical activation process is adopted, and the high adsorption capacity of the product is refined by the post-treatment scientific formulation.
introduction of powdered activated carbon product
wood powdery activated carbon is a kind of black powdery, granular or pellet shape has porous carbon, the main composition is carbon, also contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine. it also has a fine structure like graphite, which is only small and irregular in layers. it has a large surface area (500 ~ 1000m 2/ gram). it has a strong adsorption property and can adsorb gas, liquid or colloidal solids on its surface. for gases and liquids, the mass of the adsorption material can be close to the quality of the activated carbon itself. the adsorption effect is selective. in the same series of substances, the higher the boiling point is, the more likely it is to be adsorbed. the higher the pressure is, the higher the temperature is, and the more adsorption is. conversely, decompression, heating is beneficial to the gas desorption. often used in gas adsorption, separation and purification, solvent recovery, liquid sugar, petroleum oil, glycerin, drugs, drinking water and refrigerator deodorant, gas masks in the filter poison, also can be used as a catalyst or the carrier of metal salt catalysts. early production of activated carbon was made of wood, hard nut shell or animal bones, and then coal was mainly used, and the production methods of activated carbon after distillation and activation were: steam and gas activation method. the use of steam or carbon dioxide carbon activation in 850 ~ 900 ℃. chemical activation method. the activated carbon can be obtained by using the gas released by the activator or by using the active agent to impregnate the raw material.
