The nature and usefulness of coconut shell activated carbon

Coconut shell activated carbon. First of all, we introduce ourselves to ourselves, which are made of high-quality coconut shells and processed through a series of production techniques. The body is black, my body is granular, don't look long ugly, thrown in the ground and dust is similar, but there are many advantages such as developed gaps, good adsorption performance, high strength, easy regeneration, economical and durable. What is more worthy of my pride is that our brothers and sisters are active in the purification of drinking water, pure water, wine, beverages, industrial sewage, decolorization, dechlorination, deodorization, and even desulfurization in the refining industry. It’s great to be able to grow up, and it’s the same as what most people say. Seeing ugly can make a big difference.

We are active in so many industries, and today we mainly introduce our achievements in the water purification industry. Due to our inherent advantages and strong adsorption, we can adsorb toxic gases, some particles and impurities in water. Now our figure will appear in small T33, big T33. And the scope of application is more and more extensive. Moreover, we also have an indispensable position in the pure water machine. The fifth stage is generally post-activated carbon. It also improves the overall taste of pure water while filtering impurities. The high quality coconut shell can make our pure water. It is sweeter and more delicious. I hope that everyone chooses a machine with coconut shell activated carbon when choosing a water purifier. Because there is our existence, as long as there is a pure water machine, we must look for the filter shell of coconut shell activated carbon, because there is its existence.

The shell activated carbon is mainly made up of shells and wood chips, which are carbonized, activated and refined. It has the characteristics of large specific surface area, high strength, uniform particle size, developed pore structure and strong adsorption performance. It can effectively adsorb free chlorine, phenol, sulfur, oil, colloid, pesticide residues and other organic pollutants in water and the recovery of organic solvents. Applicable to pharmaceutical, petrochemical, sugar, beverage, alcohol purification industries, decolorization, purification, purification and sewage treatment of organic solvents.

Shell activated carbon is widely used in deep purification of drinking water, industrial water and wastewater, industrial water purification and gas phase adsorption, such as power plants, petrochemicals, oil refineries, food and beverage, sugar making, medicine, electronics, fish farming, shipping The water purification treatment of the industry can effectively adsorb free chlorine, phenol, sulfur and other organic pollutants in the water, especially the precursor substances of the mutant (THM), to purify and remove impurities and odor. It can also be used for industrial exhaust gas purification, gas desulfurization, petroleum catalytic reforming, gas separation, pressure swing adsorption, air drying, food preservation, gas mask, solvent carrier, industrial solvent filtration, decolorization and purification. Separation, purification, purification of various gases; recovery of organic solvents; decolorization, deodorization, refining of sugar, monosodium glutamate, medicine, alcohol, beverages; refining of precious metals; catalysts and catalyst carriers in the chemical industry. The product has more functions of decolorization, purification, impurity removal, deodorization, odor removal, carrier, purification and recovery.

[What are the principles of activated carbon adsorption]

Activated carbon is an amorphous carbon in the form of black powder or granules. The main components of activated carbon are elements such as carbon, oxygen and hydrogen. The activated carbon is irregularly arranged in structure, has pores between the cross-links, and generates carbon structure defects upon activation. Therefore, it is a porous carbon having a low bulk density, a large specific surface area, and good adsorptivity.

Activated carbon is a very good adsorbent. It uses charcoal, bamboo charcoal, various shells and high-quality coal as raw materials to crush, sieving, catalyst activation, rinsing, drying and screening of raw materials through physical and chemical methods. It is manufactured by a series of processes. It has the dual characteristics of physical adsorption and chemical adsorption, and can selectively adsorb various substances in the gas phase and liquid phase to achieve the purposes of decolorization, purification, disinfection, deodorization and decontamination and purification. Its main property is its strong adsorption. Sex.

Adsorption principle of activated carbon: Since activated carbon uses wood or coconut shell as raw material, the deep activation specific surface area is large, so the activated carbon has rich internal pores and light density, just like many pores inside the sponge have good adsorption; the carbon surface area of ​​activated carbon is very Large, so it can be in full contact with gases (impurities). When these gases (impurities) are adsorbed by micropores, they act as a purifying agent.

[Physical properties of activated carbon]

With adsorption capacity, activated carbon is a non-polar adsorbent. In addition to carbon, the main component contains a small amount of oxygen, hydrogen, sulfur and other elements, as well as moisture and ash. It has good adsorption properties and stable chemical properties. Strong acid, strong alkali, can withstand water intrusion, high temperature, high pressure and will not be destroyed. Activated carbon has a large specific surface area and particularly developed micropores, which are mainly physically adsorbed, but some chemiselective adsorption is also carried out due to the presence of surface oxides.

Its chemical properties:

The elemental carbon is composed of carbon elements and thus exhibits the same chemical nature of carbon. It is very stable at room temperature, and it does not change when exposed to sunlight or contact with moisture, nor does it react with general chemical reagents. However, at high temperatures, its chemical activity is greatly enhanced, manifested by its flammability and reducibility.

(1) Flammability:

a. Complete combustion in oxygen or in the air: carbon dioxide is produced and a large amount of heat is released.

b. Insufficient air and incomplete combustion: in addition to carbon dioxide, it also produces carbon monoxide and exotherms.

(2) Reducing:

a. The dry charcoal powder and the copper oxide are uniformly mixed to enhance the heat.

b. Hot carbon reduces carbon dioxide to carbon monoxide.

c. Hot carbon can reduce water vapor.

Brass Nut

Copper nuts made of all kinds of embossed wire (usually lead brass, such as H59, 3604, 3602). Our daily contact with the embedded knurled copper nuts are processed by precision automatic lathes. The reference standard of embedded knurled copper nut comes from GB/T809, but the technical parameters of all kinds of embedded nuts produced by our company exceed the relevant indexes required by the national standard.

Knurling copper nut is mainly used for hardware Spring, shaped spring, craft gift spring, battery spring, spring antenna,key ring, phosphorus copper spring CNC automatic lathe turning parts (copper car parts, iron, aluminum car parts), metal stamping parts, electronic parts, iron shaft, single Rachel,Rachel, iron pin, non-standard Screw nut,fittings,fasteners, wire forming (wire card holder, Model aircraft landing gear, S hook, R latch, triangle buckle, D buckle) and other hardware products, belonging to the copper nut series.
