[0028] Example one
[0029] A household water treatment slow-release vitamin C filter material, which is composed of the following components by weight percentage: polyethylene glycol (molecular weight: 20000) 72.5%, vitamin C 10%, vitamin E5%, molecular sieve 10%, sodium bicarbonate 2%, tartaric acid 0.5 %.
[0030] The preparation method of the sustained-release vitamin C filter material includes the following steps:
[0031] 1. After mixing polyethylene glycol (molecular weight 20000), vitamin C, vitamin E, molecular sieve, baking soda and tartaric acid in a drum mixer according to the ratio, they are put into the screw extruder for extrusion, and then passed through the granulator Granulation to make granular materials.
[0032] 2. Dry the produced granular material in an oven at 50°C for 3 hours to obtain a slow-release vitamin C filter material.
[0033] Fill 150g of this slow-release vitamin C filter material in a shower filter container, control the water flow rate to 8L / min, ...
