Sintering, compression extrusion activated carbon, activated carbon, activated carbon was named for their production process characteristics, the CTO, net carbon is said they eventually forming the appearance of the form of words.

Though their appearance, inner quality and production process.

Sintering: activated carbon is to use activated carbon powder materials and polymer melt mixed pore forming material, into a special mould, in 200-300 ℃ high temperature sintering; Because of this polymer bonded materials can be formed in the sintering process has open hole, mixes with activated carbon, maintained the characteristic of large specific surface area activated carbon powder, good pore forming, filtering effect is better, contact with the liquid more fully; Because of its complicated processing technology, production capacity is limited.

Compression: activated carbon is activated carbon powders mixed with inorganic liquid adhesive materials, made a special mold, with the high pressure compression molding press and the mold after drying; The high content of technology of activated carbon, filtering effect is good, but the use of inorganic binding material PM plus high pressure forming, make the filter aperture is hard to control, filter pressure drop is too large, affect the use.

Extrusion activated carbon, activated carbon and the ordinary hot-melt resin blend, into the heating screw extruder extrusion molding. The production technology of activated carbon appearance is hot melt resin after high temperature melting packages, blocked the microporous activated carbon, lost the adsorption effect, low production cost, high output. Use is a decoration, there is no any effect.

CTO (is short for chlorine, taste, and she, i.e., the chlorine, taste and smell), net carbon, extrusion and sintering, compressed activated carbon activated carbon in the broad sense they are activated carbon rod shape, can be referred to as forming activated carbon.

At present, forming activated carbon filter is becoming more and more attention in the use of the water treatment industry, the main reason is: a, forming activated carbon adsorption and intercept at an organic whole, with activated carbon adsorption is not only because it has a compact space, which can effectively intercept larger particles of impurities, effectively reduce the pollution of the water quality of physics; Second, the pore size can be adjusted, minimum 0.2 microns, is bigger than on the market of the so-called hollow ultrafiltration membrane flux is better; Three, outflow of blackwater less than granular activated carbon, the first time in the carbon black powder, after being out of later won't appear the blackwater, more not like granular activated carbon for water scour off after absorption of adsorption, the formation of secondary pollution; Four, is less than 80 purpose activated carbon powder processing, specific surface area is big, to give full play to the performance of activated carbon.

Sintering is really has the function of formed activated carbon, activated carbon as we squeeze sintering activated carbon and activated carbon, many manufacturers in order to avoid confusion, some called sintering activated carbon drill carbon Conrad (guangzhou) environmental protection, and some call BLACK MAGIC (MAGIC in BLACK carbon bar (3 m).

Sintering activated carbon technology because of its special technology, forming can be developed with activated carbon as the main body and a variety of ultrafine filter material powder mixture of compound filter. Its varieties have dedicated decoloring flavor, in addition to the organic matter, softening water quality of special filter; Remove the water of heavy metals such as arsenic, mercury, manganese, aluminum special metal filter, the light of the regional special fluoride in filter of high fluoride water; In view of the well water, soft water adding trace elements, minerals special mineralization filter; Restrain bacterial growth, adding antibacterial antibacterial filter material.

Sintering activated carbon filter for its twists and turns of cage micro aperture channel, obvious effect, filtering impurities due to the accumulation of impurities, filter easy to block the water flow will be less, therefore, water treatment companies abroad (such as 3 m) is put forward "will be blocked filter is a good filter"; To prolong the life time of the filter to reduce congestion, sintering activated carbon filter before the due effect good preprocessing prefiltering filter, such as: 1 um pp cotton filter.

Sintering activated carbon filter for appearance and low-end extrusion shape similarity, to distinguish the main there are two ways: one, the hydrophilic experiment, sintering activated carbon good hydrophilicity, drop a drop of water, immediately into the filter, and extrusion activated carbon water droplets will always float above the filter; Second, sintering activated carbon filter just water flow of the water is hot, extrusion activated carbon filter will not appear this kind of circumstance.

Sintering activated carbon filter experiment:

: 1. The coke (ink) experiment filter erect on the prepared white paper in advance, the coke directly into the experimental filter within the middle hole, later filter walls evenly seep limpid water, coke sweet thin obviously. Ordinary filter didn't this advantage.

2. Bleaching water drift stains (liquid) experiment: take a large glass (500 ml), filled with water, drip into the bleach water drift stains (liquid) 2-4 drops, stirring, pour the mixture less than half a cup to one-time cup spare; Put the filter in another big glass, then put the mixture into a large glass filter experiment middle hole, later filter walls evenly seep limpid water, fluid enough from experimental filter of big cup after (from the bottom of the cup 1 cm high), remove the filter, this time try to come up with residual chlorine liquid into the water seepage and reserve the original mixture into 2-3 drops, respectively, can be found in the exudate color clear, mixture immediately turn yellow in color. That sintering activated carbon filter with super to remove the effect of residual chlorine and its derivatives.
