Embodiment

[0031] The natural dolomite produced in Huairou, Beijing was weighed, crushed to below 35 mesh, put into a sagger, calcined in a tunnel kiln at 450°C for 3 hours, cooled to room temperature, and set aside.

[0032] Sieve to take 15 grams of dolomite powder with a particle size of 40-60 mesh (the particles can pass through the 40-mesh sieve but not through the 60-mesh sieve, the same below), take 100 grams of medical activated carbon with a particle size of 140-170 mesh, and a molecular weight of 250 1000. Put 200 grams of ultra-high molecular weight polyethylene with a particle size of 100 to 140 meshes into a stirrer equipped with a cooling jacket. After stirring at a slow speed for 90 minutes, take out the mixture and put it into a mold for extrusion molding. After sintering for 150 minutes, cool to 60°C and demould to obtain a filter element with many fine pores.

[0033] After testing, the filter element prepared by the present invention can adjust the acidic drinking wate...

Abstract

The filter medium is prepared with ultrahigh molecular weight polyethylene in 50-75 wt%, active carbon in 20-45 wt% and calcined dolomite powder in 1-8 wt%, and through mixing, sinteing at 180-280 deg.c for 60-180 min and cooling. The filter medium and the filter element therewith can regulate pH value of drinking water. The present invention is used in purifying drinking water, improving water quality and regulating pH value of drinking water to make it in slight alkaline, and has high efficiency, no secondary pollution, use convenience and low cost.

Description

technical field [0001] The invention relates to a filter medium and a preparation method thereof, a filter core formed by the filter medium, and a method for adjusting the pH value of drinking water by using the filter medium or the filter core of the invention. Background technique [0002] The pH value of a normal human body is between 7.35 and 7.45, which is weakly alkaline. Due to the increasingly refined diet of modern people, the frequent consumption of acidic substances such as meat, and the acidification of water quality caused by environmental pollution, people's physique has begun to tend to be neutral or acidic. No matter where the blood is, it should be weakly alkaline. If the blood is neutral, we cannot live; if the blood is acidic, it will cause various diseases and even death. [0003] One of the standards for good water proposed by the World Health Organization (WHO) is that the pH value is slightly alkaline. Drinking weak alkaline water for a long time ca...
