Abstract

The invention provides a method for waxing and powder coating of a lamp tube of a fluorescent energy-saving lamp. Powder tube processing is carried out on a well formed transparent glass tube which is a light tube, namely, the light tube is coated with fluorescent powder, and fluorescent powder coating is a necessary link of manufacturing of the lamp tube of the fluorescent energy-saving lamp. Before powder coating, a pin port of the light tube is immersed in molten wax, the immersion depth is determined according to requirements of the sealing procedure, the lamp tube is cooled through air after being taken out from the molten wax so that the molten wax is attached to the pin port of the light tube, and accordingly a layer of wax film is formed in the pin port. The waxed light tube is coated with the powder, and powder slurry flowing out can not be attached to the pin port due to the fact that the wax is not hydrophilic. Accordingly, during powder coating, the situation that when the powder slurry is discharged, a powder tube is stained, and accordingly a defective product is caused is avoided.

Description

The method of tube of energy-saving fluorescent lamp applying wax dusting

Technical field

The present invention relates to the method for a kind of tube of energy-saving fluorescent lamp applying wax dusting, belong to the electric light source industry of chemical field.

Background technology

The dusting of energy-saving fluorescent lamp in the market adopts without accumulated powder dusting machine more, but because the powder falling of its technological design reason tube cell lamp base often can cause floral tube, the powder falling of outside causes in fluorescent tube and can not coat fluorescent material exactly, affects the qualification rate of lamp tube powder coating; Tube cell needs crocus link simultaneously, and crocus also can produce the electricity charge and labour cost, and produces fluorescent tube breakage in crocus operation, and production efficiency is low.

Summary of the invention

In order to overcome the deficiency of existing energy-saving fluorescent lamp exposed conduit coating process, the invention provides the method for a kind of tube of energy-saving fluorescent lamp applying wax dusting, be exposed conduit by the transparent glass tube of forming, carry out tube cell processing, namely exposed conduit is coated to fluorescent material, this is the necessary link that tube of energy-saving fluorescent lamp is manufactured, before dusting, the lamp base mouth of pipe of exposed conduit is immersed in the wax liquid melting, the degree of depth immersing is determined according to the requirement of sealing process, air-cooled after fluorescent tube is taken out from wax liquid, wax is attached on the mouth of pipe of exposed conduit lamp base, the inside and outside one deck cere that forms of the mouth of pipe of lamp base like this, exposed conduit after applying wax is carried out to dusting, due to this not hydrophilic characteristic of wax, the powder slurry flowing out just can not be attached on the mouth of pipe of lamp base, so can not producing, dusting cause the floral tube of tube cell to cause waste product because of powder slurry blanking.

When exposed conduit coat powder from powder coating machine out, now the binding agent of powder slurry is ineffective, powder slurry has been fixed on exposed conduit inside, now fluorescent tube has completed the operation of tube cell substantially, be that tube cell enters tube-baking machine baking by the exposed conduit that coats powder, because the temperature highest region of baking box is at 500 ° more than C, this temperature is higher than the volatilization peak of wax, the temperature of baking can be melted volatilization by the wax of tube cell, fluorescent tube entire body white now, and applying wax position after wax volatilization can reserve glass true qualities by nature, again tube cell is carried out to crocus operation with regard to not needing like this.

The invention has the beneficial effects as follows, not only saved the electricity charge, artificial and time, also saved fluorescent material, reduced production cost, and material is easily purchased simultaneously.

Accompanying drawing explanation

Fig. 1 is energy-saving fluorescent lamp exposed conduit, and wherein 1 is fluorescent tube, and 2 is lamp base;

Fig. 2 is the exposed conduit of applying wax of energy-saving fluorescent lamp, and wherein 1 is fluorescent tube, and 2 is lamp base, and 3 is lamp base applying wax place;

Fig. 3 is energy-saving fluorescent lamp tube cell, and wherein 1 is fluorescent tube, and 2 is lamp base, and 3 is lamp base applying wax place.

Embodiment

Before 1 dusting of Fig. 1 fluorescent tube, the lamp base of exposed conduit 2 mouths of pipe are immersed in the wax liquid melting; Fig. 2 takes out fluorescent tube 1 rear air-cooled, and wax is attached on the mouth of pipe of fluorescent tube 1 lamp base 2, so inside and outside one deck cere, i.e. the lamp base applying wax place 3 of forming of the mouth of pipe of lamp base 2.Fluorescent tube after applying wax 1 is carried out to dusting, and powder slurry is pumped into the inside of fluorescent tube 1 by the position at lamp base applying wax place 3, and due to this not hydrophilic characteristic of wax, the powder slurry of outflow just can not be attached on the mouth of pipe of fluorescent tube 1 lamp base 2.

Fig. 3 enters tube-baking machine baking after fluorescent tube 1 coats powder, because the temperature of baking box is at 500 ° of C, the wax on fluorescent tube 1 lamp base 2 is melted volatilization by temperature after baking, the now inner dusting of fluorescent tube 1 completes, fluorescent tube 1 is entire body white also, and vitreous true qualities have been reduced at lamp base applying wax place 3, tube cell needs the part of crocus naturally to reserve, and has carried out the operation of fluorescent tube crocus like this with regard to not needing again.

Claims

1. the method with the dusting of tube of energy-saving fluorescent lamp applying wax, it is characterized in that: before dusting, the lamp base mouth of pipe of exposed conduit is immersed in the wax liquid melting, air-cooled after fluorescent tube is taken out from wax liquid, wax is attached on the mouth of pipe of exposed conduit lamp base, the inside and outside one deck cere that forms of the mouth of pipe of lamp base like this, exposed conduit after applying wax is carried out to dusting, due to this not hydrophilic characteristic of wax, the powder slurry flowing out just can not be attached on the mouth of pipe of lamp base, and dusting can not produce and cause the floral tube of tube cell to cause waste product because of powder slurry blanking.
