Abstract
The present invention relates to a manufacturing technique of an electric light source, particularly to a glass clamping and sealing technology for maintaining a passage of a gas discharge tube in the gas-tight sealing and connecting process of a glass tube and the gas discharge tube. The glass clamping sealing technology is characterized in that high temperature resistance powder layer materials are uniformly coated on the inner wall of the gas discharge tube, and the high temperature resistance powder layer materials are prepared from Al2O3, SiO2 or CaCO3, etc. and binding liquid. Coating length is 60% to 110% of sealing length, and the coating thickness of the high temperature resistance powder layer materials is from 15 to 50 micrometers. The present invention has the principle that when the outer surface layer of the gas discharge tube is burnt, a coating layer of the gas discharge tube is solidified into a supporting thin shell, and 95% to 100% of original passage of the gas discharge tube can be maintained. Therefore, the present invention solves the defects of gas leakage, large stress and small hole diameter and enhances the qualified rate of products.
Description
The present invention relates to the electric light source manufacturing technology, is a kind of glass clamping ﹠ sealing technology that keeps the blast pipe latus rectum when carrying out hermetic seal about glass-tube and blast pipe.
At present, clamping ﹠ sealing technology is adopted in the blast pipe sealing-in of producing electricity-saving lamp, electric light source bulb and vacuum device both at home and abroad mostly.Because domestic raw material consistency and equipment precision problem often can not satisfy the requirement of existing clamping ﹠ sealing technology, therefore, factors such as the diameter of glass material, wall thickness, flame-worked position, intensity change, and make existing clamping ﹠ sealing technology can not keep the blast pipe exhaust pipe passage, often cause that the blast pipe latus rectum diminishes, disadvantage such as gas leakage, glass strain are big, its latus rectum only can reach the 25%-30% of exhaust pipe passage, also can only reach 65% abroad.
For addressing the above problem, the invention provides a kind of simple and easy to do, obvious results glass clamping ﹠ sealing technology, making it extensively to fit can be in the processing and manufacturing of electricity-saving lamp, electric light source bulb and vacuum device, and reliability of products and qualification rate can increase substantially.
The present invention realizes by following steps, it is characterized in that the high temperature resistant bisque 3 of blast pipe 2 coated inner wall in fusion process blast pipe 2 by the flame scorification, high temperature resistant bisque 3 wedging surface layer of glass, be solidified under the softening temperature of glass, when the shell that supports blast pipe 2 under the extruding of shell soften glass in clamping during with blast pipe 2 fusion.Described high temperature resistant bisque 3, its powder slurries are chosen Al
2O
3, SiO
2Or CaCO
3Formulated etc. one of binding liquid such as high temperature resistant powder and pure water, ethanol or acetate butyl, powder, liquid weight ratio are 1: 0.4-0.85, powder slurries need stir and keep even.The particle mean size of high temperature resistant dusty material may be selected to be the 5-15 micron.The thickness and the adhesion firmness of an amount of selection decision coating bisque of the shape of this material, granularity, binding liquid and weight ratio.Select exotic material all can not play the adverse chemical reaction with various materials in the lamp.The preparation of powder slurries finishes, and blast pipe one end is immersed in the powder slurries, and immersion depth is the 60%-110% of blast pipe sealing-in length.Take out the blast pipe that immerses the powder slurry, get rid of surplus powder in the pipe, powder layer thickness is controlled in the 15-50 micrometer range, the horizontal positioned blast pipe is put into baking oven or natural draft drying, treat that the bisque intensive drying is solidified in the blast pipe after, remove the powder that the pipe outer wall attaches, in order to avoid cause sealing-in gas leakage.Adhesion firmness falls the back bisque with blast pipe from 0.3 meter not to be had obvious dry linting and is as the criterion.The blast pipe of inwall dusting, outer wall cleaning is come in the hopper by the sealing-in direction, carry out the clamp operation with outer casing shell 1, its manufactured goods as shown in Figure 1.Except that above-mentioned coating method, also can adopt methods such as spraying, obliterating to form bisque.
Principle of the present invention be in fusion process blast pipe by the flame scorification, at this moment, be coated in the high temperature resistant bisque wedging surface layer of glass of inwall, be solidified into shell, this shell has very strong support force under the softening temperature of glass, so that the shell soften glass is under the extruding of clamping, with the blast pipe alloying process in, can keep the 95%-100% of exhaust pipe passage.
The invention has the beneficial effects as follows:
1, can guarantee between outer casing shell and the blast pipe fully welding, make blast pipe keep the 95%-100% of exhaust pipe passage, thereby avoid gas leakage, stress is big, the aperture is little defective.
2, technological operation is easy, reliable, does not need change equipment, need not often regulate flame, can directly use stronger flame-worked, has alleviated labor strength, under the prerequisite of ensuring the quality of products, can relax the requirement to the glass material size.
3, because the blast pipe aperture becomes big, the quite domestic raising of admittance ability 3-4 doubly than 1.5 times of external raisings, therefore, helps improving the vacuum degree of manufactured goods in the exhaust air technique process; Again because the fusion of blast pipe and outer casing shell is fine and close, firm, manufactured goods do not have and leak phenomenon slowly, and residual stress is little, do not burst, and the intensity height, thus product percent of pass is increased substantially.
