Embodiment Construction

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

[0013] Perlite 14, Bauxite 22, Aluminum Nitride 4, Sodium Bicarbonate 6, Medical Stone Powder 4, Nano Carbon 2, Rapeseed Oil 5, Clay 26, Sodium Tripolyphosphate 3, Propylene Glycol 6, Ethylene Glycol 2, Tantalum boride 2, ammonium chloride 3, modified attapulgite 30, appropriate amount of water.

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

[0015] Calcinate attapulgite at 460-480°C for 3-4 hours, take it out, cool it, soak it in 10-12% sodium hydroxide solution for 2-3 hours, take it out, wash it with pure water, dry it and grind it into powder; add aluminum nitride equivalent to attapulgite powder weight 40%, 20% dandelion powder, 4% sodium tripolyphosphate, 3% medical stone powder, 3% graphite, 4% copper powder, Mix and stir for 30-40 minutes, then spray soybean oil equivalent to 5% of the weight of attapulgite, and stir at 13000-16000 rpm for ...

Abstract

The invention discloses a perlite filter element and a preparation method thereof. The perlite filter element is characterized by being prepared from the following raw materials in parts by weight: 12-14 parts of perlite, 20-22 parts of bauxite, 4-6 parts of aluminium nitride, 4-6 parts of sodium hydrogen carbonate, 3-4 parts of medical stone powder, 2-3 parts of nano carbon, 5-6 parts of colleseed oil, 24-26 parts of clay, 3-4 parts of sodium tripolyphosphate, 4-6 parts of propylene glycol, 2-3 parts of ethylene glycol, 1-2 parts of tantalum boride, 2-3 parts of ammonium chloride, 30-35 parts of modified attapulgite clay and a proper amount of water. The stress in the filter element is uniform through regional sintering, and the phenomena of breakage and the like are avoided; bubble holes are uniform; the perlite filter element has excellent high-temperature resistance and corrosion resistance and has the outstanding advantages of high purification efficiency, high-temperature resistance, low pressure loss, corrosion resistance, long service life, capability of removing micro dust from air and the like.

Description

technical field [0001] The invention belongs to the technical field of filter materials, in particular to a perlite 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 environments, and redu...
