Abstract
A kind of helix fluorescent lamp powder-coating method, purpose is that to overcome the luminous efficiency that the serious became uneven of bisque that certainly led to owing to common coating process causes low, waste the defective of the valuable fluorescent material and the increase roasted tube energy, technical scheme is: a port to the double helix exposed conduit quantitatively injects the powder slurry earlier, blow to this port in limit rotation exposed conduit limit then, quantitative powder in this port is starched under the acting in conjunction of gravity and gas pressure, move to the part that does not still have the powder slurry to apply along the exposed conduit inwall, the place that needs fluorescent material in exposed conduit is all evenly applied, and quantitative powder slurry uses up, in xeraphium slurry and roasted tube step, need blow (heat) gas and rotation tube cell to a port of tube cell.
Description
Technical field
The present invention relates to make helix fluorescent lamp particularly superfine pipe diameter (the dusting field of external diameter of pipe in 1.8 ~ 6mm) helix fluorescent lamp technologies, concrete is a kind of powder-coating method of improved helix fluorescent lamp.
Background technology
In the prior art, fluorescent lamp all need apply fluorescent material at its glass tube inwall, and fluorescent material produces visible light ultraviolet exciting down, brings light to the world.The glass tube that we generally will also not apply fluorescent material is called exposed conduit, the method that applies fluorescent material at present is to prepare phosphor slurry earlier substantially, be coated with by filling again or vacuum is inhaled and to be coated with, make and be full of phosphor slurry in the exposed conduit, unnecessary powder slurry is discharged under the effect of gravity, so just forms the relatively thinner phosphor powder layer of one deck at the exposed conduit inwall.The method that unnecessary powder slurry is discharged in this dependence action of gravity is reasonable when making straight tube fluorescent lamp, but when making the double helix fluorescent lamp, because glass tube is seriously crooked, cause phosphor slurry not flow out smoothly, just produced the serious uneven situation of bisque thickness, both influence light efficiency, wasted the valuable fluorescent material and the waste roasted tube energy again.200620126617.9 pairs of this defectives of patent have been carried out relevant improvement, and we think that the weak point of this patent is an inefficiency, is not suitable for large-scale production substantially; And be not suitable for the dusting of superfine pipe diameter especially, because superfine pipe diameter can be referred to as capillary substantially, if its inner powder slurry has only the effect of gravity, it is mobile to be quite difficult.Patent application 200710068965.4 also propose to improve dusting, and it at first will fill with the powder slurry again with unnecessary pouring out in the pipe, compare some waste with the quantitative injection powder slurry of this law and work efficiency low, superfine pipe diameter is not then gone out unnecessary powder substantially starches.
Summary of the invention:
In order to overcome the deficiency in the existing technology, the invention provides novel dusting method of bi-helix fluorescent lamp, concrete steps are as follows:
Step 2, xeraphium slurry: in a port of the exposed conduit (hereinafter referred to as tube cell) of completing steps one, blow hot gas (30 ~ 80 ℃) and rotation tube cell, in 40 ~ 100 ℃ environment, make the powder slurry drying progressively in the tube cell.
Step 3, roasted tube: in a port of completing steps two tube cells, blow, and make its temperature of bearing progressively reach about 500 ℃ progressively to reduce to room temperature again, make materials such as binding agent volatilization in the powder slurry, decompose until whole removals.This step should be rotated tube cell, makes being heated of tube cell more even; When high temperature is reduced to about 250 ℃ of left and right sides, preferably air blowing is changed into nitrogen blowing or inert gas, make moist to avoid fluorescent material.
Said (heat) gas that blows in a port of the present invention should clearly be only to blow to one of two ports, can not replace port.Because for superfine pipe diameter, be used in the method for the alternately port blowing of adopting usually in the extra heavy pipe footpath, the wind that then is blown into is difficult to enter from a port, comes out from another port, thereby is difficult to the xeraphium slurry and influences the roasted tube effect.
Advantage of the present invention is: because bisque is even, do not had thick powder to the stopping of light, the luminous flux of lamp is improved; Owing to there has not been thick powder, the energy that roasted tube needs reduces; Owing to there has not been thick powder, used fluorescent material is reduced, reduced cost.

Fig. 2: to the schematic diagram of exposed conduit rotation, air blowing
Numeral among the figure is:
1, quantitative powder is starched
Embodiment:
The present invention solves the technical scheme that its technical problem recommends to adopt: the method for inhaling with perfusion or vacuum, quantitative powder slurry is injected in the port of double helix exposed conduit, the outer presumable powder slurry of this port is removed, be connected on this port with a flexible pipe, by flexible pipe in exposed conduit, blow (can be hot gas), rotate exposed conduit simultaneously, powder in the exposed conduit is starched under the effect of gravity and gas pressure, move to the part that does not still have the powder slurry to apply along the exposed conduit inwall, the place that needs fluorescent material in exposed conduit is all coated, and quantitative powder slurry uses up substantially.Quantitative what of powder slurry can obtain by test several times, and the size of air blowing and the speed of rotation also obtain by test, and it is full according to being that the powder slurry substantially evenly is coated with.Place it in then on the device of a rotation, make a port of tube cell keep logical 30 ~ 80 ℃ hot gas, under 40 ~ 100 ℃ environment, make the powder slurry dry.Carry out roasted tube according to step 3 again, tube cell should rotate during roasted tube, also can not rotate.
The present invention mainly illustrates the new method in the double helix coating powder of fluorescent lamp technology, and for the cleaning in the coating process, be coated with steps such as diaphragm, pipe cutting, crocus, owing to be known technology, the present invention does not do new improvement to it, so do not give unnecessary details at this paper.
The present invention to the electrode of fluorescent tube is respectively: the dusting of the helix fluorescent lamp of hot cathode, cold cathode, external electrode, electrodeless and combination electrode all is suitable for; Profile to helix fluorescent lamp is respectively: it is that the dusting of the garden garden cylindricality or non-cylindricality all is suitable for that (parallel with the helix tube center line) pin, full spiral, snail and main projection envelope helix tube are arranged, therefore all in protection scope of the present invention.
