Abstract

The invention relates to a preparation method of a sintered activated carbon water purification filter core, wherein a rod-like activated carbon water purification filter core is prepared. The preparation method comprises the preparation steps: (1) grinding coconut shell activated carbon powder, ultra-high molecular polyethylene, negative ion powder and tourmaline powder respectively; (2) mixing the raw materials; (3) drying after moulding; (4) carrying out sintering heat treatment; (5) cooling and demoulding to obtain moulded rod-like activated carbon; (6) cutting into sections, adhering andprocessing into the finished product, and thus obtaining the sintered activated carbon water purification filter core. The coconut shell activated carbon powder, ultra-high molecular polyethylene, negative ion powder, tourmaline powder and silver-loaded 4A zeolite are mixed, subjected to press sintering moulding to prepare the rod-like activated carbon water purification filter core. The filter core has the advantages of high strength, good purification effect, and good antibacterial performance, and the functional material negative ion powder and tomaline make purification and activation integrated, and have antioxidant effect. The preparation method has the advantages of simple and feasible implementation, easily obtained raw materials, low cost, strong pollution removal ability, and long service life, and is suitable for large-scale industrialized production.

Description

technical field [0001] The invention relates to a preparation method of a water purifier filter element, in particular to a preparation method of a sintered activated carbon water purification filter element. Background technique [0002] Activated carbon, as a carbonaceous material with well-developed pores and adsorption, has been widely used in the field of water purifiers. Activated carbon is equivalent to the liver outside the human body and plays a role in removing toxins. [0003] In the process of water purification, if granular activated carbon is used, there will be many disadvantages. For example, under a certain water pressure, due to the fast water flow, the contact time between water and granular activated carbon is very short, the adsorption force is not strong, and the granular activated carbon During the washing process of the water flow, a gap filter will be formed, so that a part of the water cannot touch the activated carbon when passing through the carbo...
