Accompanying drawing explanation
Fig. 1 is the process chart of the present invention.
Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, with
Lower combination drawings and Examples, are further elaborated to the present invention.Should manage
Solving, specific embodiment described herein only in order to explain the present invention, is not used to
Limit the present invention.
With reference to Fig. 1, details are as follows for the concrete technology of the dosing technology of the present invention.
Step (1), high-pressure discharge light source is dry with the installed surface cleaning of trigger
Only, installed surface coats one layer of 703 silicon rubber, place under natural environment and treat 703
Silicon rubber solidifies.The material used when being cleaned the installed surface of light source is preferred
For absolute ethyl alcohol, its cleaning effect is good, uses safety.703 silicon rubber are a kind of viscous
Connecing property is good, high intensity, free from corrosion single-component room-temperature-vulsilicone silicone rubber, has excellent
Electrical insulation capability, sealing property and ageing-resistant performance, can be at-50 DEG C-+250 DEG C
In the range of Long-Time Service.703 silicon rubber solidification process be one from surface internally
Solidification process, within 24 hours (room temperature and 55% relative humidity) will solidification 2～
The degree of depth of 4mm, if site location is relatively deep, is especially being less easily accessible to air
Position, the completely crued time will extend, if temperature is relatively low, hardening time
Also will extend.Thin layer is only needed in view of 703 coated silicon rubber, because of
Only need to place under natural environment during this step (1) solidification and be not less than 4h.
Step (2), the high-pressure discharge light source being coated with 703 silicon rubber is put into
In baking oven, take out after toasting 2h ± 0.5h under the conditions of 70 DEG C ± 10 DEG C.This step energy
Enough guarantee that 703 silicon rubber cling on light source surface.
Step (3), is placed on encapsulating die on high-pressure discharge light source, by pressure
Sensitive tape cements in the outer contacting face position of encapsulating die with high-pressure discharge light source.
Step (4), is placed on trigger in encapsulating die, by the output line of trigger with
The extraction electrode silk scolding tin of high-pressure discharge light source welds, and is coated with at pad
Cover 703 silicon rubber, place under natural environment and treat 703 silicon rubber solidifications.Same step
(1), 703 silicon rubber are placed under natural environment and are not less than 4h so that it solidifies.
After step (3) and (4) complete, light source and trigger complete tentatively in encapsulating die
Location.
Step (5), puts into high-pressure discharge light source, trigger and encapsulating die
In baking oven, take out after toasting 2h ± 0.5h under the conditions of 70 DEG C ± 10 DEG C.This step is true
703 silicon rubber of Bao Hanjiedianchu can reliably cement.
Step (6), takes appropriate casting glue and stirs, put into vacuum defoamation machine
Carry out degasification deaeration, inclined heated plate 30min ± 5min.This step is the standby of casting glue
With the stage, when implementing this step, need to grasp according to required casting glue amount
Making, when required amount is bigger, this step needs to repeat 3-5 time, to reach enough
Usage amount.Furthermore, it is contemplated that high pressure to be met is fire-retardant, seal, resistant to elevated temperatures want
Ask, it is preferred to use the famous model in south is the casting glue of ND-313.
Step (7), pours in encapsulating die by the casting glue of deaeration, and inside is empty
Between completely fill out, under natural environment place treat that casting glue solidifies, needed for solidification time
Between be not less than 48h, during practical operation, casting glue solidification time by natural environment
The impact of humidity, humidity is the biggest, and casting glue is the fastest for hardening time.
Step (8), removes encapsulating die, by high-pressure discharge light source excess surface
Casting glue remove, and surface wipes is clean, complete embedding work.
The technique of the present invention solves High-Voltage Insulation, firmly installing property and thermal characteristics and asks
