Product Overview

 

carbon molecular sieves (CMS) is a carbon adsorbent with a relatively uniform microporous structure developed in the late 20th century. It has wedge slit micropores close to the diameter of the adsorbed molecules, which can separate the molecules with different three-dimensional structure sizes. Carbon molecular sieve is mainly based on the principle of gas molecular size, polarity and diffusion speed difference for gas separation, has the advantages of high adsorption strength, high hardness, heat resistance, acid resistance and chemical stability. As a new adsorbent, carbon molecular sieve is mainly used for the separation of some gas components in the air, and can also be used for the separation of some organic compounds. At present, it has been widely used in food hygiene, medical treatment, catalysis, air separation, nitrogen production, hydrogen recovery in coke oven gas and so on.

Product Features

 

High adsorption selectivity: The adsorption capacity of carbon molecular sieve for nitrogen is much higher than that of other gases, and nitrogen can be separated through selective adsorption, thus providing high purity nitrogen.

Rapid adsorption and release: The surface of the carbon molecular sieve has many micropores and mesoporous pores, and nitrogen molecules can quickly enter these pores, so as to achieve rapid adsorption. Similarly, carbon molecular sieves can release adsorbed nitrogen molecules very quickly, so that it can provide a continuous supply of nitrogen.

High storage capacity and long service life: Due to the large surface area and high selectivity of carbon molecular sieve, it can adsorb a large number of nitrogen molecules, and because of its chemical stability, high temperature resistance, corrosion resistance and other characteristics, the service life of carbon molecular sieve is relatively long.


Application Fields

 

Air separation: Carbon molecular sieves can be used to separate oxygen and nitrogen from the air, which is one of its main applications. Through pressure swing adsorption (PSA) process, carbon molecular sieves can efficiently adsorb oxygen and achieve nitrogen enrichment.

Petrochemical: In the petrochemical industry, carbon molecular sieves can be used for gas separation, purification and purification processes. For example, the removal of carbon dioxide and hydrogen sulfide from natural gas, and the separation of ethylene and propylene from petroleum cracking gas, etc.

Metal heat treatment: In the process of metal heat treatment, nitrogen is often used as a protective atmosphere. The carbon molecular sieve nitrogen machine can provide high purity nitrogen to ensure that the metal material is not oxidized during the treatment process.

Electronic manufacturing: The electronics industry has high purity requirements for nitrogen, and carbon molecular sieve nitrogen machines can meet this demand. Nitrogen is used in chip manufacturing, semiconductor packaging and other processes to prevent oxidation and contamination of products.

Food preservation: Nitrogen can be used for food preservation and storage to extend the shelf life of food. Carbon molecular sieve nitrogen machines can provide nitrogen for food processing and storage.

Hydrogen recovery: In some industrial processes, exhaust gas containing hydrogen is produced. Carbon molecular sieves can be used to recover these hydrogen and improve resource utilization.

Medical field: Carbon molecular sieves also have certain applications in the medical field, such as for oxygen concentrators to provide a high concentration of oxygen for patients who need oxygen inhalation.

Great value and easy to install!
Color: Black, Color: Black
I only needed 3 of the 4 shelves so I have one as a backup! Very easy to install as well. The shelves feel sturdy and I’ve never had any issues!

quality matches cost + instructions unnecessarily tedious
Color: Brown, Color: Brown
The material is real wood but don't assume that means quality - it's still very cheap feeling, and very lightweight. But once installed they are quite stable, and they look great from afar. I got a darker colored one and the stain does come off very easily. One of the shelves had a huge manufacturer sticker on it and it took off the stain when I removed it, and a bit of the stain also came off when I wiped the shelves down with a wet cloth. It'll be dry dusting from now on, I suppose. Also, they did not fit snugly into the corner - when one side is pushed flush to the wall, it forces the other side to pull away from the wall a little bit. It wasn't a drastic space, maybe like 1/8th of an inch, but it is still something to note. I am fine with the cheap quality as they are, after all, pretty cheap, so I'd say they are worth exactly as much as they cost. Personally I am happy with the purchase - just thought I'd warn. Secondly - if you want to follow the instructions exactly, you will need two people unless you have inhuman agility. But I also think the instructions were a bit asinine and tedious. They want you to line up the LOOSE shelf and brackets with a leveler to mark where the brackets go on the wall, then put in the wall screws, hang the brackets on them, balance the shelf on the brackets to mark on the SHELF where the brackets will be attached, take the brackets off the wall to screw them into the shelf, then put the combined shelf-bracket unit once again on the wall screws and finally screw those in tight. In hindsight, you can just mark where the brackets should go on the SHELF (not wall), screw the brackets into the shelves, THEN level the shelf on the wall and screw the whole unit into the wall together. We were really baffled why the instructions didn't have us do that instead of spending extra time (and frustration) trying to juggle all the loose pieces and tools. But I'm not engineer-minded, nor have I ever installed corner shelves before, so maybe there would be some kind of issue with doing it that way that I can't predict.

Good shelving decor
Color: Black
Easy to install and perfect for a corner display of Disney decor. They are lightweight, so we didn't put anything heavy on them, but the brackets seem sturdy enough that we could probably put something moderately weighty on them.

GREAT BUY
Color: Natural Wood
LOVE these shelves! Got them for each side of the bed to put books. Really elevates the room, and is cuter than just a simple straight book shelf.

Not made well
Color: Natural Wood
Not made well. Wood had some warping. Only 2 screws per bracket. Not very sturdy.
