Abstract
The invention provides a baking-free once screen printing process for metallization of a ceramic-vacuum tube. The process is implemented as follows: a metal paste is respectively printed on the two end surfaces of the ceramic-vacuum tube once, wherein the metal paste consists of molybdenum, manganese, alumina, silicon oxide, magnesium oxide, barium oxide, phthalate, terpineol and hydrogenated castor oil. The process has the advantages that because the metal paste is improved, the defects existing in the traditional hand work and screen printing processes are completely overcome and heating and baking links are omitted; the process has obvious energy-saving and environmentally-friendly effects, high time-saving work efficiency, good evenness, strong coherence (the error of the thickness isbetween 2 mu m and 4 mu m) and high density; and a good technical basis is provided for a downstream process.
Description
Technical field
This invention relates to ceramic-vacuum tube metallization printing art area.
Background technology
At present, the metal paste application is one of metallized gordian technique of ceramic-vacuum tube, the paste that require to apply after high-temperature roasting good planeness, consistence is strong, density is high.Usually adopt two kinds of production technique in the industry.The one, handwork: ceramic-vacuum tube is placed on the rotating disk with dial rotation through after the pre-treatment; Dip in writing brush and to get paste application on end face; Apply again after the drying; Apply the lower surface again after three to four times so repeatedly, thickness error is at 12um-18um, poor flatness, repeat to apply often, work efficiency is low, long flow path, smell are big; The 2nd, silk-screen printing technique; Traditional reticulated printing technology mainly comprises:
A, ceramic-vacuum tube pre-treatment: with ceramic-vacuum tube through ultrasonic cleaning, drying;
B, inner ribs coated metal paste: brush by hand through the metal paste coated in ceramic vacuum tube tendons, Liang dry, repeated three to four times a coating;
C, the silk screen printing of end plane metal paste: with the metal paste through silk screen printing on an end face of ceramic-vacuum tube; After the oven dry of end plane metal paste; Change silk screen, all over rare slightly metal paste, repeat on the end face of ceramic-vacuum tube, to republish once with more preceding; After the oven dry, use other end more once more with quadrat method printing ceramic-vacuum tube.Its purpose of repeating print is with second time rarer metal paste, revises and fill up the cream plane defect that exists in the first pass printing.
D, muscle ring, upper surface and lower surface all be covered with the metal paste ceramic-vacuum tube again through roasting, burn nickel after test package.
Traditional-handwork operation and the silk-screen printing technique link is many, work efficiency is low, accessory is numerous and diverse; Maximum defective is that the employed thinner of manual coating must be the extremely strong solvent of volatility, is being convenient to repeat apply after volatilization, the drying fast, therefore; Smell is big in the production, harmful HUMAN HEALTH; Traditional silk screen printing paste technology end face must repeat print secondary and baking secondary, energy consumption is big, because of baking also discharges a large amount of obnoxious flavoures, polluted air.
Summary of the invention
The object of the invention is exactly the defective to above-mentioned traditional hand operation and silk-screen printing technique, and provides a kind of ceramic-vacuum tube metallization not have silk-screen printing technique of baking.
No vacuum metallized ceramic baking a screen-printing process, including the end metal paste screen printing process, characterized in that the end face of the metal paste is baked without a screen printing, screen printing metal paste end process steps as follows: the ceramic tube placed on a tray, through the screen printing process of the metal paste is printed on an end face of the ceramic tube, and then turn the ceramic tube with a tray placed on the surface by screen printing process the metal paste is printed on the ceramic tube on the other an end surface Liang dry;
The metal paste is made up of metal-powder and sticker;
The parts by weight of raw materials proportioning of metal-powder is:
Molybdenum 60-78 manganese 8-12 aluminum oxide 3-6 silicon oxide 7-16
Natural manganese dioxide 4-8 barium oxide 2-4;
The parts by weight of raw materials proportioning of sticker is:
Phthalic ester 100 Terpineol 350 140-170 THIXCIN 60-80;
The parts by weight of raw materials proportioning of metal paste is:
Metal-powder 100 sticker 25-45.
The holder tool is made up of base, backing plate, circular cone column bracket dish, spring and one group of cushion block, and backing plate is installed on the base, and circular cone column bracket dish is installed on the backing plate; One group of cushion block is installed in respectively on the circular cone column bracket dish; Spring is installed in the base, and an end of spring is against on the base, and the other end withstands on the backing plate.Cushion block is Mitsubishi's taper, and the angle of cushion block and backing plate is 50 °-60 °, preferred 55 °.Advantage of the present invention is: the present invention is owing to improved the metal paste; The various defectives that exist in traditional hand operation and the silk-screen printing technique have been overcome fully; Saved the heated baking link; Effects of energy conservation and environmental protection significantly, the work efficiency that saves time height, good planeness, consistence strong (thickness error is between 2 μ m-4 μ m), density be high, to lower procedure the good technical basis is provided.

Accompanying drawing 2 is accompanying drawing 1 a sectional structure synoptic diagram.
Embodiment
Concrete process step is:
A, ceramic-vacuum tube pre-treatment: with ceramic-vacuum tube through ultrasonic cleaning, drying;
B, inner ribs coated metal paste: Using a brush with hand painted ceramic metal paste on the inner tube, Liang dry, repeated three to four times a coating;
C, end plane metal paste silk-screen printing technique step are: ceramic-vacuum tube is placed on the holder tool; The metal paste is printed on the end face of ceramic-vacuum tube through silk-screen printing technique; Again ceramic-vacuum tube is turned over a face and be placed on the holder tool, the metal paste is printed on another end face of ceramic-vacuum tube through silk-screen printing technique;
D, the ceramic-vacuum tube that two end faces all are printed with the metal paste are placed on the special car.
