Description
Technical field
The present invention relates to " connection of shell, service wire, base or manufacture " technical field, particularly a kind of manufacture method of ceramic cartridge, further, is a kind of manufacture method being used as the ceramic discharge shell of fluorescent tube.
Background technology
In recent years, along with the requirement that people are thrown light on for indoor large-area, the higher ceramic discharge shell of color developing is by the increasing manufacture for fluorescent tube, although its working temperature and the light efficiency silica glass material all than past employing is higher, but be olive shape because it manufactures shape, and need integral type manufacture, therefore there is very large technical difficulty.
Existing ceramic cartridge method such as the applicant Chinese patent literature CN102543623 disclosed in the 4 days July in 2012, comprise the following steps: (1) provides the external mold and cerul internal mold with container cavity, and the outline shape of cerul internal mold and the outline shape of container cavity match; (2) cerul internal mold is inserted container cavity inner position, between the inwall of container cavity and cerul internal mold, form cavity; (3) material powder is filled with in cavity; (4) remove external mold after powder sclerosis will be expected and form discharge vessel idiosome;
(5) heating is utilized to be removed by cerul internal mold.
There is following defect in such design: as is known to the person skilled in the art, in such as shell series products manufacturing processed, its most critical is also the step that difficulty is the highest is exactly how to remove internal mold, heating means mentioned in technology described in CN102543623 (5) step, the universal means of those skilled in the art is heated by outside to promote the temperature of cerul internal mold, finally makes the melting of cerul internal mold flow out.As everyone knows, cerul internal mold there will be expansion in the process of heating, and the coefficient of expansion of paraffin and other organic materials is comparatively large, and the coefficient of expansion of ceramic idiosome after being shaped is very little, be subject to shape restriction, the opening at cerul internal mold two ends is very little (diameter is generally no more than 1mm), cannot offset its bulging force completely, therefore for avoiding the ceramic powder hardened to burst, the speed that necessary control temperature promotes, this process often needs last from days, and working efficiency is lower, and cost is very high.
For improving this defect, NGK Insulators Ltd Chinese patent literature CN1827330 under one's name discloses a kind of manufacture method (gel method) of molding, its major technique core utilizes soup compound to be contained in forming model as molding material, wherein at least adopt a part of slaking material or solvability material in soup compound, utilize soup compound and internal mold contact surface generation physical-chemical reaction, this contact surface is formed sake cavity, and utilize this cavity to offset the bulging force of internal mold in heat-processed completely, final molding is avoided to burst in the process of de-internal mold.
Undeniable, technology disclosed in Chinese patent literature CN1827330 solves the problem that molding bursts in mold process in taking off substantially, but still it is not enough to there is part: for realizing soup compound and internal mold contact surface generation physical-chemical reaction smoothly, need in soup compound to comprise ceramic powder, metal-powder, or the mixed powder of these two kinds of powders, and dispersion medium and gelating agent etc., the mixing of multiple material must cause the rising of the loaded down with trivial details of technique and cost, simultaneously, also above kinds of ingredients can be comprised in the product of final formation, its effect as fluorescent tube is slightly poor than pure stupalith, also more may to environment.
Equally, for solving the similar defect brought in technology described in CN102543623, General Electric Corporation Chinese patent CN1489558 under one's name discloses a kind of manufacture method (gel method), it produces the inner mould core that namely can bear certain pressure by low molecule and compound through foam process, inner mould core is made again to have hole or present spumescence, the inner mould core of even approximate ghost.Its effect is, when the de-internal mold of postorder heating, the spumescence hole due to inner mould core changes the expansion direction of internal mold, and then counteracts the outside bulging force of internal mold, and the idiosome that same guarantee has been shaped does not burst by External Force Acting.
Equally, technology disclosed in Chinese patent literature CN1489558 also solves the problem that molding bursts in mold process in taking off substantially, but also there is similar deficiency: the foam process of low molecule and compound is higher for the requirement of component, time, the physical-chemical reaction occurred in idiosome manufacturing processed, equally may to environment.
Therefore, in order to cost-saving, reduce pollution on the environment simultaneously, need a kind of internal mold, powder body material component single, chemical reaction does not occur in the fabrication process, and comparatively fast can not there is again the ceramic cartridge manufacture method that shell bursts in demould time.
Summary of the invention
Technical problem to be solved by this invention is that ceramic cartridge manufacture method production efficiency of the prior art is lower, cost is higher and may to environment, and provide a kind of internal mold, powder body material component is single, chemical reaction does not occur in the fabrication process, and comparatively fast can not there is again the ceramic cartridge manufacture method that shell bursts in demould time.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
A manufacture method for ceramic cartridge, comprises the following steps:
