Abstract

The invention provides a ceramic filter core used for purifying gasoline. The ceramic filter core is prepared from the following raw materials by weight: 40 to 50 parts of aluminum slag, 20 to 30 parts of a waste paper product, 10 to 15 parts of kaolin, 5 to 10 parts of zeolite powder, 3 to 4 parts of magnesium carbonate, 1 to 2 parts of carboxymethyl cellulose, 2 to 4 parts of n-butyl methacrylate, 10 to 15 parts of silica powder, 4 to 6 parts of sodium carbonate, 4 to 6 parts of konjak flour, 5 to 8 parts of honey, 1 to 2 parts of sulfuric acid powder and 2 to 3 parts of boric acid powder. A preparation method for the filter core comprises the following steps: step-by-step ball milling and mixing of the raw materials; slip casting; molding; and sintering. The filter core provided by the invention is prepared with the aluminum slag as a base material and konjak powder, honey and the like as a binder and a pore forming agent, so the prepared filter core has the characteristics of a small bore diameter, a great permeation volume, small resistance, high efficiency, a great filtering area, good adsorption and filtration performance, pressure resistance, corrosion resistance, etc. and has porosity of 50 to 56%.

Description

A kind of ceramic element for purifying gasoline and preparation method thereof

Technical field

The present invention relates to the filter core manufacture field, be specifically related to a kind of ceramic element for purifying gasoline and preparation method thereof.

Background technology

Development along with society, the reinforcement of environmental consciousness, people are more and more higher to drinking the quality standards for water requirement, need less filtering accuracy, require simultaneously to have the decontamination effect improving of sterilization and anticorrosion, the filtration of the purifier that the automobile different sites is filled requires also more and more higher, and the filter core in purifier plays Main Function, need to design the filter core of different-effect, satisfy the varying environment demand.

Summary of the invention

The invention provides a kind of ceramic element for purifying gasoline and preparation method thereof.

The present invention adopts following technical scheme:

A kind of ceramic element for purifying gasoline is characterized in that, is prepared from by the raw material of following weight part:

Aluminium slag 40-50, discarded paper product 20-30, kaolin 10-15, zeolite powder 5-10, magnesiumcarbonate 3-4, carboxymethyl cellulose 1-2, n-BMA 2-4, silicon powder 10-15, soda ash 4-6, Rhizoma amorphophalli powder 4-6, honey 5-8, sulfate powder 1-2, boric acid powder 2-3.

The preparation method of described ceramic element for purifying gasoline is characterized in that, comprises the following steps:

(1) the discarded paper product that at first will collect are pulverized, and then by formula rate, starting material are all joined in ball grinder, add appropriate distilled water, and with the rotating speed of 100rpm, ball milling 8 hours obtains mixed slurry;

(2) with the standing slaking 10-12 of mixed slurry hour, then slowly pour moulding in the die cavity of plaster mould into, obtain hollow filter core base substrate; Standing 4-6 hour, the demoulding obtained the filter core green compact;

(3) with green compact at 90-105 ℃ of dry 3-4 hour, then under protection of inert gas, sinter ceramic element under 900-1300 ℃.

Beneficial effect of the present invention:

Filter core of the present invention is take the aluminium slag as base-material, utilized waste, saved cost, reduced the pollution of environment, added the auxiliary materials such as discarded paper product, kaolin, zeolite powder, then add Rhizoma amorphophalli powder, honey as binding agent, pore-forming material, obtain filter core through grinding, sintering, prepared filter core has not only that the aperture is little, Air permenbility is large, resistance is low, the efficient high, and filtration area is large, and Adsorption Filtration Properties is good, have simultaneously characteristics withstand voltage, erosion resistance, void content reaches 50%-56%.
