Therefore, the compound method of a kind of fluorescence grinding is provided, to can be by the improvement to coating process, use painting method and the controlled heating of multi-region segmentation looping back streaming, improve the uniformity of dusting, the most successively dusting, improve the control of coating layer thickness, by bisque weight check, reduce substandard product and flow out, just become the problem that those skilled in the art need solution badly.
Summary of the invention
It is an object of the invention to provide the compound method of a kind of fluorescence grinding, to can be by the improvement to coating process, use painting method and the controlled heating of multi-region segmentation looping back streaming, improve the uniformity of dusting, the most successively dusting, improve the control of coating layer thickness, by bisque weight check, reduce substandard product and flow out.
For solving technical problem described in background technology, the present invention by the following technical solutions:
A kind of coating process of glass-tube fluorescent material, the processing step of its dusting is:
Step 1, material select: select the glass-tube 20 of different size and appropriate phosphor slurry, in case using, the specification that its glass-tube is corresponding is:
Diameter includes specification: T8, diameter: 26 ± 0.5；Specification: T9, diameter: 29 ± 0.5；Specification: T10, diameter: 32 ± 0.5, and wall thickness is all between 0.7 0.8, length includes specification: 18/20W, length: 660 ± 1；Specification: 25W, length: 813 ± 1；Specification: 36/40W, length: 1270 ± 1；
Heat before step 2, dusting: before dusting, first once open electric switch, blower fan and heater to heat up, the predetermined temperature of dusting is 80 120 DEG C, when temperature is heated up to predetermined production temperature, open pulp absorbing pump, by carrying out heat treated in advance, it is possible to enable slurry to reach the dusting temperature of requirement at short notice, avoid because local heating's inequality produces the situation of powder and pump housing bonding simultaneously.
Step 3, coating processing: after opening pulp absorbing pump, under the effect of pulp absorbing pump, slurry is evacuated to cone through the pump housing, is coated with in cylinder, flow out when slurry reaches to be coated with cylinder spillwag chute, then in being back to agitator, and constituted circulation with this, then begin through cladding process and glass-tube is carried out uniform dusting, dusting temperature during dusting is divided into four thermals treatment zone, and is respectively as follows:
I district: 70 90；II district: 80 100；III district: 60 80；IV district: 80 100.
Suitably can be turned on and off heating warm area, by looping back painting method and the controlled heating of multi-region segmentation of streaming according to seasonal variations when heating operation, make dusting more uniform, the thermal treatment zone can open and close at any time simultaneously, to reduce the control difficulty of bringing-up section, makes temperature the most various easily-controllable.
Step 4, the inspection of laminated weighting school: after having coated, mark the bright glass-tube of weighing of 3 different sizes, fluorescent material weight is weighed after fully drying, and every 2 hours, it is weighed once, then whether technological requirement is met according to fluorescent material weight, by weighing to the sample timing fluorescent material that carries out the most repeatedly, to judge qualification rate, and produce in enormous quantities.
The invention has the beneficial effects as follows:
1), by the improvement to coating process, use painting method and the controlled heating of multi-region segmentation looping back streaming, improve the uniformity of dusting, the most successively dusting, improve the control of coating layer thickness.
2), by bisque weight check, reduce substandard product and flow out.
