Embodiment Construction

[0012] A tourmaline functional ceramic filter element is made of the following raw materials in parts by weight (kg):

[0013] Tourmaline powder 40, bamboo charcoal powder 14, medical stone powder 8, potassium feldspar powder 9, polyvinyl alcohol 6, zeolite powder 3, sodium persulfate 3, urea 13, modified bentonite 20, appropriate amount of water.

[0014] Described modified bentonite is made by following method:

[0015] Calcinate bentonite at 520-540°C for 3-4 hours, take it out, cool it, soak it in 10-12% hydrochloric acid solution for 2-3 hours, then soak it in 10-12% sodium hydroxide solution for 1-2 hours , take it out, wash it with pure water, dry it and grind it into powder; then add aluminum nitride equivalent to 40% of the weight of bentonite, 18% of apocynum powder, 3% of brown sugar, 3% of chromium boride, and 4% of Tungsten carbide powder, mixed and stirred for 30-40 minutes, and then sprayed with 7% bentonite weight Cross-linking agent TAC , Sti...

Abstract

The invention discloses a tourmaline functional ceramic filter core and a preparation method thereof, and is characterized in that the tourmaline functional ceramic filter core is prepared from the following raw materials, in parts by weight: 40-45 parts of a tourmaline powder, 12-14 parts of a bamboo charcoal powder, 6-8 parts of a medical stone powder, 7-9 parts of a potassium feldspar powder, 4-6 parts of polyvinyl alcohol, 3-4 parts of a zeolite powder, 2-3 parts of sodium persulfate, 12-13 parts of urea, 20-25 parts of modified bentonite, and a proper amount of water. The tourmaline powder is fully contacted with filtered matters, thus the contact area is greatly improved, and the infrared radiation and negative ion release of tourmaline are fully exerted and are beneficial to human body. The tourmaline functional ceramic filter core has the outstanding advantages of high purification efficiency, high temperature resistance, low pressure loss, corrosion resistance, long service life and the like, and can also remove micro-dust in air.

Description

technical field [0001] The invention belongs to the technical field of filter materials, in particular to a tourmaline functional ceramic filter element and a preparation method thereof. Background technique [0002] Filter materials are widely used in chemical industry, electric power, metallurgy, petroleum, electronic appliances, machinery and other industries; the most common ones are automotive air filters, which are used to filter the air entering the engine, and remove particulates and particles in the air. Mechanical impurity components are blocked, preventing these components from entering gasoline, diesel or engine oil, and ensuring the normal operation of the engine. There are also a large number of filter materials used in air conditioning systems. Now the environmental air pollution is very serious, which greatly endangers human health. Air filter materials can absorb various harmful particles in the air, prevent them from entering people's living or working env...
