Background technology
LED lamp is replacing traditional luminescent lamp as a kind of novel energy-conserving and environment-protective lighting source and is entering interior lighting field.With Glass tubing, make the straight pipe type LED lamp of shell owing to exchanging with traditional T8 fluorescent tube, the lighting source that has business and domestic lighting to be worth as a kind of utmost point obtains just rapidly human consumer's approval.
Because the brightness of LED is very high, can not directly as lighting source, use, must by outer cover, utilize frosted or diffuse-reflectance coating that light is carried out to secondary distribution through installing additional after outer cover, form soft light output.Traditional coating manufacture craft is first powder and solvent to be made to suspension, then adopts the method for spraying or extrusion to be coated to the inwall of Glass tubing suspension, becomes uniform diffuse-reflectance coating (being also light diffusion coating) after heated-air drying and shaping.Because the suspension rate of drying with water as solvent is slow, form top coating compared with the thin and poor problem of thickness up and down that bottom coating is thicker, cause luminous (diffused light) non-uniform phenomenon, simultaneously, coating very easily produces bubble in technological process, causes coating after dry, to form bubble and prints, and has seriously affected appearance of coat quality, become unacceptable product or waste product, thereby make manufacturing cost greatly increase.Traditional technology is after Glass tubing inwall applies, to utilize to the method for Glass tubing inwall blowing hot-air to make coating dry gradually from top to bottom, and the upper and lower thickness of coating is poor larger.
Utility model content
The utility model relates to the device of water-soluble smooth diffusion coating in a kind of LED of making fluorescent tube, has effectively eliminated bubble, makes again that the upper and lower thickness of coating is poor is less than 5%.
In a kind of LED of making fluorescent tube, the device of water-soluble smooth diffusion coating comprises powder slurry storage pool, stirrer, surge pump, a ultrasonic wave froth breaking bucket, the first magnetic valve, twice ultrasonic ripple froth breaking bucket, the second magnetic valve, power collecting bucket, the 3rd magnetic valve, Glass tubing and blowing hot-air mouth device, powder slurry storage pool respectively with surge pump, one time ultrasonic wave froth breaking bucket connects, surge pump is connected with a ultrasonic wave froth breaking bucket, in powder slurry storage pool, be provided with stirrer, powder slurry storage pool one side is provided with and takes back powder groove, a ultrasonic wave froth breaking bucket, the first magnetic valve, twice ultrasonic ripple froth breaking bucket, the second magnetic valve, power collecting bucket, the 3rd magnetic valve, Glass tubing is connected in turn with blowing hot-air mouth device.
Preferably, on a described ultrasonic wave froth breaking bucket and twice ultrasonic ripple froth breaking bucket, be respectively equipped with anti-overflow hole.
The beneficial effects of the utility model are:
1. ultrasonic wave froth breaking bucket and twice ultrasonic ripple froth breaking bucket utilize ultrasonic wave principle that the small bubbles in coating are removed, by twice ul-trasonic irradiation in liquid, produce two kinds of effects, a underbalance effect, be exactly that the interior part of liquid occurs tensile stress and forms negative pressure, the reduction of pressure makes to be originally dissolved in the dissolved gas supersaturation of liquid, and overflow from liquid, another effect is that powerful tensile stress " tears " a cavity liquid, be called cavitation, in cavity, be liquid vapour or the another kind of gas that is dissolved in liquid, it may be even vacuum, the small bubbles that form because of cavatition can constantly move with the vibration of surrounding medium, grow up or overflow suddenly and vanish,
2. the utility model is flowing downward after the relation of rate of drying and temperature in process fully having studied powder slurry, use the inside and outside blowing hot-air simultaneously technique of heating can allow upper end coating be dried rapidly, make upper end thickening, reduce so upper and lower thickness poor, make that upper and lower thickness is poor can equal zero.
Accompanying drawing explanation
Fig. 1 is one-piece construction schematic diagram of the present utility model;
Fig. 2 be of the present utility model be to coordinate schematic diagram for reducing the poor blowing hot-air mouth of upper and lower thickness with the fluorescent tube after dusting.
