Description
Technical field
The present invention relates to tube cell preparation technical field more particularly to a kind of powder-coating methods free of cleaning of T8 straight tube LED tube cell.
Background technique
The tube cell of LED light during the preparation process, needs to carry out dusting to the inner wall of glass tube, the quality of dusting directly affects
To the translucent effect of fluorescent tube.Slurry is usually poured into pump from the upper end of glass tube, makes slurry by weight by current coating process
Power leaves, and flows out from the lower end of glass tube, and after then toasting, one layer of bisque is thus formed on glass inside pipe wall.
Such as application No. is 200910182998.0 Chinese patents to disclose a kind of powder coating method of fluorescent lamp tube, including following
Step: (1) washed bright pipe is put into starching machine on, is blown into hot wind and dries bright pipe;(2) when bright pipe advances to upper powder position
When, by one end nozzle of spraying pump pipette tips insertion fluorescent tube, starting pump carries out the slurry that dusts, and when slurry is sprayed at the top of fluorescent tube, stops
Dust slurry, and removes lance head;(3) by the other end nozzle of the pipette tips insertion fluorescent tube of air draught pump, starting air draught pumps air draught, works as powder
When slurry is flowed at nozzle, then stop air draught, and remove air draught pipette tips;(4) tube cell enters drying area drying.
Since the both ends of fluorescent tube are needed when in use for assembling, it cannot be coated with slurry at the both ends nozzle of fluorescent tube,
Bright pipe needs to carry out later period cleaning to the both ends bisque of bright pipe after the dusting by above-mentioned technical proposal.This method and process
Complexity, it is not convenient enough, reduce working efficiency.
In addition, after the dusting of above-mentioned technical proposal, the powder layer thickness that slurry is formed after solidifying in glass inside pipe wall is not equal enough
One, cause the light transmittance at each position of tube cell different, causes of low quality.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of powder-coating methods free of cleaning of T8 straight tube LED tube cell.This
The powder-coating method simple process of invention, without being cleaned to the bisque of tube cell both ends nozzle after dusting;And T8 straight tube obtained
The caliper uniformity of LED tube cell, bisque is good, and each position light transmittance of tube cell is essentially identical;The conjugation of bisque and glass tube simultaneously
It is good, it is not easily to fall off.
The specific technical proposal of the invention is: a kind of powder-coating method free of cleaning of T8 straight tube LED tube cell, including following step
It is rapid:
A, match powder: weighing the raw material of following volumes part respectively: 750-850 parts of resin glue dilutions, 1-2 parts of levelling agents,
