How to distinguish coconut shell activated carbon0dingxinda92020-12-16 23:27:57
1. Coconut shell activated carbon belongs to the type of nut shell activated carbon. Its main characteristics are low density and light touch. The weight in the hand is significantly lighter than coal-based activated carbon. yongruida granular carbon   For the same amount of activated carbon, the volume of coconut shell activated carbon is usually larger than that of coal-based activated carbon.  2.The shape of coconut shell activated carbon is usually broken granules and flakes, while shaped activated carbon, such as columnar and spherical activated carbon, is mostly coal-based carbon.  3.Because the coconut shell activated carbon has a low density and a light hand feel, it can be put into water. Coal-based carbon usually sinks faster, while coconut shell activated carbon floats in the water for a longer time, as the activated carbon absorbs water molecules to reach fullness. powdered activated carbon for water treatment  It will gradually sink to the bottom of the water when the weight is increased. When the activated carbon is fully sinked, you will see a small bubble wrapped around each activated carbon, which is bright and transparent, which is very interesting.  4.Coconut shell activated carbon has a small molecular pore structure. When activated carbon is placed in water, many very fine blisters (just visible to the naked eye) will occur when the activated carbon is placed in the water, and they will continuously float to the surface of the water. Activated carbon usually has a macromolecular pore structure, and the bubble phase that occurs is also relatively large.

What is activated carbon usually made of? bamboo or coconut shell? 02020-10-10 00:08:28
Imagine this: You’ve got one hour to pack for your dream vacation, and all you can take with you is a carry on – what do you toss in your bag? I can tell you one item that would definitely be in mine, whether I’m headed to Iceland’s hot springs or a beach in Bali – activated charcoal.granular activated carbon price The stuff is basically the Swiss Army knife of natural living – one bottle can serve as first aid, a portable spa treatment, and a tooth whitener. And that’s just a few of the uses for activated charcoal. Although it sounds similar to the charcoal bricks you throw in a BBQ grill to make dijon rosemary marinaded shish kabobs, it’s actually very different. Sometimes called activated carbon, activated charcoal is made by burning natural materials – often hardwood, bamboo or coconut shells – at high temperatures until they transform into adsorbent granules that are ground into powder. To understand how activated charcoal works, let’s talk about absorption and adsorption. You already know what absorption is – when fluid is dissolved into a liquid or solid, like water being absorbed by a paper towel. Adsorption is a little different – think of it more like a magnet binds strongly to the surface certain substances, grabbing onto them so they can’t get away. Millions of micropores in activated charcoal grab onto heavy metals, viruses, poisons, certain types of bacteria, and other substances. Just two grams (about 4 capsules of coconut-derived activated charcoal) has a larger surface area than an entire football field.ningxia yongruida carbon co. ltd 
How to regenerate coconut shell activated carbon in brine0dingxinda92021-03-09 21:48:09
