Description

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

Technical field

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

Background technology

Along with the development of society, the reinforcement of environmental consciousness, the quality criteria requirements of people to tap water is more and more higher, need less filtering accuracy, require the decontamination effect improving with sterilization and anticorrosion, also more and more higher to the filtering requirement of the purifier that automobile different sites fills, the filter core in purifier plays Main Function simultaneously, need the filter core designing different-effect, meet varying environment demand.

Summary of the invention

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

The present invention adopts following technical scheme:

For purifying a ceramic element for gasoline, it is characterized in that, being 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 the described ceramic element for purifying gasoline, is characterized in that, comprise the following steps:

(1) first pulverize collecting the discarded paper product come, then all joined in ball grinder by starting material by formula rate, add appropriate distilled water, with the rotating speed of 100rpm, ball milling 8 hours, obtains mixed slurry;

(2) mixed slurry is left standstill slaking 10-12 hour, then slowly pour in the die cavity of plaster mould shaping, obtain hollow filter core base substrate; Leave standstill 4-6 hour, the demoulding, obtains filter core green compact;

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

Beneficial effect of the present invention:

Filter core of the present invention with aluminium slag for base-material, make use of waste, save cost, decreased 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, filter core is obtained through grinding, sintering, obtained filter core not only has that aperture is little, Air permenbility is large, resistance is low, efficiency high, and filtration area is large, and Adsorption Filtration Properties is good, have feature that is withstand voltage, erosion resistance, void content reaches 50%-56% simultaneously.

Embodiment

For purifying a ceramic element for gasoline, be prepared from by the raw material of following weight (kg):

Aluminium slag 50, discarded paper product 25, kaolin 12, zeolite powder 8, magnesiumcarbonate 3, carboxymethyl cellulose 2, n-BMA 3, silicon powder 12, soda ash 5, Rhizoma amorphophalli powder 5, honey 6, sulfate powder 1, boric acid powder 2.

For purifying the preparation method of the ceramic element of gasoline, comprise the following steps:

(1) first pulverize collecting the discarded paper product come, then all joined in ball grinder by starting material by formula rate, add appropriate distilled water, with the rotating speed of 100rpm, ball milling 8 hours, obtains mixed slurry;

(2) mixed slurry is left standstill slaking 11 hours, then slowly pour in the die cavity of plaster mould shaping, obtain hollow filter core base substrate; Leave standstill 6 hours, the demoulding, obtains filter core green compact;

(3) by green compact 105 DEG C of dryings 3 hours, then under protection of inert gas, at 1200 DEG C, sinter ceramic element into.

The obtained filter core aperture of the present embodiment at 2 μm-12 μm, void content 55%, filtration velocity 24ml/hr.cm ²(height of water 200mm), folding strength about 16Mpa.
