Discrimination of activated carbon filter cotton filter

Mar 06, 2020

There are usually three index values for the quality of carbon filter products: iodine adsorption value, ccl4 adsorption value, and ethylene blue adsorption value. If these index values on the filter element, the higher the index value, the stronger the adsorption capacity, the better the quality of the carbon filter product. The values of these values represent the ability to absorb organic compounds, vapors, and discoloration, respectively. Sometimes the adsorption of carbon filter element has a life span. Remember to replace it on time.

Carbon filter is a true positive deep structure, with dual basic functions of filtering and purification. The precision of the filter is 10 micron nominal filtering precision. There is no need to add filter aids during application, nor does it need to be filtered after carbon treatment. Each carbon filter contains 160 grams of plant sulfur-free activated carbon filter cotton particles. It is suitable for purification treatment of electroplating solution, because the filter element does not precipitate fibers or other substances, which causes pinholes or brittle fracture of the plating layer. Compressive strength: 0.4Mps Application temperature: 52 ° C

Carbon filter in actual life, with the serious pollution of water sources, everyone attaches great importance to drinking water ideology and China's full support and popularization of drinking water nutrition and health, because carbon filter is an important component of water purifiers, Therefore, it is especially important to choose a reliable water purifier filter. The carbon filter manufacturer, Sanbi Filter Materials, teaches you to identify the authenticity of the water purifier activated carbon filter cotton filter.

1. Gravimetric method

The most obvious feature of activated carbon filter cotton is its high internal structure porosity, which also determines its strong adsorption capacity. The more porosity and the more complex the structure, the stronger the adsorption capacity, the better the quality of the carbon filter product. However, we can't identify it with the naked eye when buying, and from the perspective of material density, the more the internal structure porosity, the smaller its density, and the lighter the weight of the same volume of filter element. Therefore, we can tell by the feel of the hand. The quality of advanced carbon filter products is relatively light.

2. Ignition method

The combustion method is a commonly used method when we identify the quality of a certain product? It is a destructive test and is suitable for activated carbon filter cotton. First break a little filter, then take a little activated carbon filter cotton from the filter, burn it on the fire, and then take it away. If it turns black immediately, it is true that the activated carbon filter cotton turns white and is still very The fiery red is ordinary charcoal. This is because charcoal is generated when combustion is insufficient, and the internal structure has much less pores than activated carbon filter cotton, so its adsorption capacity is naturally greatly reduced.

3. Observe the indicator values carefully

Carbon filter element generally has several index values to measure the quality of carbon filter product: iodine adsorption value, ccl4 adsorption value, methylene blue adsorption value. If these index values on the filter element, the higher the index value, the stronger the adsorption capacity, the better the quality of the carbon filter product. The values of these values represent the ability to adsorb organic compounds, vapors, and discoloration, respectively. Sometimes carbon adsorption has a life span, so remember to replace it on time.
