Abstract
The invention discloses an automatic plane screen paste printing technology for metalizing a ceramic discharge tube. Apart from a paste preparation step, the technology also comprises the following steps of: 1) fixing a ceramic piece; 2) mounting a stainless steel sieve, wherein the screen mesh of the stainless steel sieve is 100, and tension is about 300+/-20 N/cm<2>; 3) adjusting a doctor blade, an objective table and a leakage blade; 4) uniformly distributing the paste; and 5) printing the paste. Through the invention, the metallized paste layer has uniform thickness, good consistency and smooth surface; the technology adopts automatic operation and has high paste coating efficiency; and the process is easy to control, and the quality is easy to guarantee.
Description
Technical field
The present invention relates to ceramic discharge tube metallization seal cream technique, refer more particularly to a kind of ceramic discharge tube metallization automatic plane silk screen seal cream technique.
Background technology
Ceramic metallization silk screen seal cream technique is at ceramic surface printing layer of metal paste, through making it to realize the firm connection between pottery and the metal level behind the annealing in hydrogen atmosphere.Traditional-handwork silk screen brushing technique is that manual work is painted on the ceramic member surface with brush with the metal paste, and annealing in hydrogen atmosphere forms after oven dry.Common practices is: metallization molybdenum manganese cream powder, ethyl cellulose solution, the terpinol that 1, will configure are mixed with paste by a certain percentage; 2, with celloidin solution or methocel solution discharge tube is bonded on the special-purpose plate glass, uses the oven dry of infra-red drying stove; 3, on silk screen, brush the layer of metal paste with row's brush, wipe the surplus cream at the silk screen back side off, again silk screen is placed on the porcelain spare,, make the paste on the silk screen be printed in porcelain spare end face, form in oven for drying again with row's brush or scraper plate extruding silk screen with scraper plate.
The main feature of above-mentioned traditional-handwork silk screen brushing technique is simple to operate, but the cream layer thickness deviation of hand-screen is big, and uniformity is poor, and its thickness deviation reaches ± 15 μ m, and seal cream surface can produce groove, is prone to sagging; Manual seal cream is in the environment of constant temperature, constant humidity, to carry out, and paste needs the water bath with thermostatic control heating, and ceramic whiteware spare also will guarantee certain temperature, and the control parameter is many, difficult quality guarantee; Manual in addition silk screen seal cream inefficiency needs operating personnel many.
Summary of the invention
For overcoming the deficiency that traditional-handwork silk screen brushing technique exists, the object of the present invention is to provide a kind of ceramic discharge tube metallization automatic plane silk screen seal cream technique, it is even that it has metallization cream layer thickness, high conformity, surface smoothing is coated with cream efficient advantages of higher.
In order to realize the object of the invention, technical scheme of the present invention is following:
A kind of ceramic discharge tube metallization automatic plane silk screen seal cream technique except joining the cream step, also comprises the steps:
Porcelain spare is fixed:
Adopt fixedly porcelain spare of special-purpose eccentric fixture;
Stainless steel sift is installed:
Special stainless steel sift is installed on the automatic plane screen process press;
Regulate doctor, objective table, spillage cutter:
Regulate automatic plane screen process press doctor, make and regulate doctor to be pressed on the porcelain spare each position stressed evenly; Regulate and make porcelain spare suitable after objective table rises with the spacing of stainless steel sift silk screen; Regulating the spillage cutter enables to scrape and totally covers the slurry that leaked the stainless steel sift silk screen behind the slurry;
Equal plaster ointment:
Paste is added in the automatic plane screen process press stainless steel sift, start and let the printing machine dry running for several times, make paste evenly be covered with the stainless steel sift silk screen;
Seal cream:
Porcelain spare to be printed is placed on the objective table, start automatic press, begin to print cream;
After calibrator is surveyed the cream layer thickness, regulate the thickness of the pressure of doctor and porcelain spare automatically with fine setting seal cream cream layer.
Wherein, adopt fixedly porcelain spare of special-purpose eccentric fixture, need not dry.Special-purpose eccentric fixture includes clamping plate with holes and eccentric sphere.
In addition, in seal cream step, after automatic plane screen process press polishing wax calibrator is surveyed the cream layer thickness, regulate the thickness of the pressure of doctor and porcelain spare automatically, can realize working continuously with fine setting seal cream cream layer.
The invention has the beneficial effects as follows:
1, automatic plane screen process press institute matel coated cream layer thickness is even, high conformity, and its metallization cream layer thickness is 75 ± 5 μ m, is superior to 85 ± 15 μ m of traditional-handwork serigraphy.
2, automatic plane screen process press institute matel coated cream laminar surface is level and smooth, no groove, and the sagging size is little.
3, to be coated with cream be at room temperature to carry out to automatic screen printing machine, and paste, porcelain spare all are room temperature environments, only needs to guarantee that the viscosity of paste just can guarantee to be coated with the quality of cream.
4, metallizing paste and porcelain spare engaging force is good, and strong adhesion is difficult for falling the cream phenomenon in turn-over and fluvial processes, and the loss of minimizing process improves acceptance rate.
5, automatic screen printing machine can be worked continuously, and carries out automation mechanized operation, and it is high to be coated with cream efficient, and speed is fast, and action required personnel are few.
