Abstract
The present invention relates to a ceramic filament guider of titanium oxide and a manufacturing process thereof. The ceramic filament guider is prepared from the materials of titanium dioxide, barium carbonate, zinc oxide, calcium carbonate, magnesium oxide and other components, and the manufacturing process comprises the steps of the preparation of the raw materials, injection molding, trimming, wax removal, sintering, polish, etc. The product of the present invention has the advantages of high surface smoothness and moderate ceramic hardness, the tension force of fiber filaments can be adjusted, and a whitening phenomenon can be eliminated, so that the product is a high-quality filament guider.
Description
The present invention relates to the filar guide in a kind of chemical fibre spinning industry.
Used filar guide in the present chemical fibre spinning industry, general is this material with aluminium sesquioxide all, its characteristics are that hardness is big, wear resistance good, but its surfaceness is bigger, lousiness or fracture of wire phenomenon often appear in producing use, most often, in spinning process, because silk had been gone up finish, and the filar guide surface irregularity strengthens the tension force of silk, causes on the filar guide surface and forms a large amount of " white powder " phenomenons, chemical fibre silk grade is descended, have a strong impact on the economic benefit of chemical fiber factory.
The objective of the invention is: a kind of ceramic filar guide based on titanium oxide and manufacturing process thereof are provided, this filar guide surface smoothness height, porcelain hardness is moderate, and adjustable integralization fibril tension force is eliminated " white powder " phenomenon.
Technical scheme of the present invention is:
A kind of ceramic filar guide based on titanium oxide, its material comprises following main component:
A. titanium dioxide 85%--95%;
B. barium carbonate 2%--5%;
C. zinc oxide 1%--3%;
D. lime carbonate 2%--5%;
E. magnesium oxide 1%--3%.
A kind of manufacturing process of ceramic filar guide based on titanium oxide, its technology comprises following key step:
(1) ratio in titanium dioxide 85%--90%, barium carbonate 2%--5%, zinc oxide 1%--3%, lime carbonate 2%--5%, magnesium oxide 1%--3% takes by weighing five kinds of main raw materials, put into the taking-up in about 48 hours of ball milling bottle mill, putting into baking oven dries, temperature remains on about 120 ℃, 3 hours, make that the moisture content in the compound all loses;
(2) take by weighing a certain amount of paraffin and beeswax and melt, sieve falls impurity, puts into stirrer, keep about 80 ℃ of constant temperature, the compound that baking is good slowly adds in the stirrer, and the limit edged stirs, the oleic acid that takes a morsel evenly adds, and stirs and finishes discharging in 4--5 hour, and preparation of raw material is finished;
(3) annotate to press: confected materials is melted, put into the vacuum stirring thermocompressor, the temperature that keeps material is injected mould and is treated to take out product after cold slightly, the release about 70 ℃;
(4) deburring: with gauze product is wiped roughly, unnecessary part is pared off, comprise mould Kazakhstan furan muscle, wipe a time with cotton at last earefully, make product very smooth;
(5) de-waxing: product is deposited in the aluminum oxide powder, maintain a certain distance between product and the product, slowly heat up, allow the wax in the product slowly get rid of, and make product that certain rigidity be arranged, be convenient to clean with water by aluminum oxide, after temperature is reduced to room temperature, take out product, remove the aluminum oxide powder that its surface is gathered, so that become the porcelain sintering;
(6) sintering: product is placed refractory materials by certain loading height, progressively be warmed to 1250 ℃, and kept 2 hours, be cooled to room temperature more gradually, take out product, sintering is finished;
(7) product is polished.
The further manufacturing process of the present invention is:
(1) takes by weighing five kinds of main raw materials in proportion, add in the ball milling bottle, add distilled water again, water is higher slightly than material, and ball milling 48 hours takes out, oven dry, compound after the oven dry enters and burns in the stove to 900 ℃--and 950 ℃, make above five kinds of components be prefabricated into sosoloid, yet compound is put into the taking-up in about 48 hours of ball milling bottle mill again, putting into baking oven dries, temperature remains on about 120 ℃, 3 hours, makes that the moisture content in the compound all loses;
(2) take by weighing the paraffin, 0.05% beeswax that account for compound 20% and melt, sieve falls impurity, puts into stirrer, keep about 80 ℃ of constant temperature, the compound that baking is good slowly adds in the stirrer, and the limit edged stirs, get 0.03% oleic acid and evenly add, stir and finished discharging in 4--5 hour, preparation of raw material is finished;
(3) annotate to press: confected materials is melted, put into the vacuum stirring thermocompressor, the temperature that keeps material is about 70 ℃, and the pressure of air injects mould and treats to take out product after cold slightly, the release more than 0.7Mpa;
(4) deburring: with gauze product is wiped roughly, unnecessary part is pared off, comprise mould Kazakhstan furan muscle, wipe a time with cotton at last earefully, make product very smooth;
(5) de-waxing: product is deposited in the aluminum oxide powder, maintain a certain distance between product and the product, slowly heat up, allow the wax in the product slowly get rid of, progressively be warming up to about 900 ℃ by aluminum oxide, and make product that certain rigidity be arranged, be convenient to clean with water, after temperature is reduced to room temperature, take out product, remove the aluminum oxide powder that its surface is gathered, so that become the porcelain sintering;
(6) sintering: product is placed refractory materials by certain loading height, progressively be warmed to 1250 ℃, and kept 2 hours, be cooled to room temperature more gradually, take out product, sintering is finished;
(7) product is polished: comprise that machine is thrown and hand is thrown:
Machine is thrown and is divided thick the throwing and thin the throwing again:
The thick throwing: product is put in the shake throwing machine, adds silicon carbide again, the ratio of silicon carbide and product is 3: 1, add an amount of water (product and silicon carbide abrasive are all soaked damp getting final product) again, open shake throwing machine, add some liquid detergents again, liquid detergent and product ratio are 1: 400, and shake was thrown about three days;
The thin throwing: the product that will slightly throw is put into shake throwing machine, adds the alumina abrasive of joining different shape again, adds entry and superfine alumina powder again, the ratio of product and alumina abrasive, water, superfine alumina powder is 40: 80: 2: 1, the shake throwing time is about 4 days, and product is pulled out, cleans up;
Hand is thrown: will shake the product thrown with thick iron sand shelling, the rubber granularity is about 150 orders, and next articles for use 320 order superfine Steel Wire Cloths grind again, is stained with the lapping paste product of firmly regrinding with dacron terylene cloth again, wipes clean with clean cloth and gets final product grinding the product of getting well.
Advantage of the present invention is:
1. product surface of the present invention is highly polished, and roughness can reach below 0.2 μ, can not make the chemical fibre silk produce the lousiness phenomenon.
2. product hardness of the present invention is moderate, can bear the high-speed of chemical fibre spinning, can not improve the tension force of silk again, can guarantee the manufacturing technique requirent of chemical fibre spinning.
