Description
Technical field：
The present invention relates to the technique of voltage equalizing ball, balance pipe covering insulating layer, is specifically related to a kind of covering voltage equalizing ball, balance pipe one
The technique of body formula structure ultrathick insulating layer.
Background technology：
Voltage equalizing ball, the thickness of insulating layer of balance pipe are ultrathick insulating layer at 20 millimeters.Existing voltage equalizing ball, balance pipe insulating layer
There are the following problems for covering process：The moisture of insulating layer cannot leak out completely, can cause to produce between each layer of insulating layer
Gap forms air cavity, and product can not use, and cause the qualification rate of product low, wastes more.In addition drying time is grown, and work efficiency is low.
The content of the invention：
The technical problems to be solved by the invention, which are to provide a kind of moisture of insulating layer, to be leaked out completely, each layer of insulating layer
Between will not form air cavity, drying time is short, the high covering voltage equalizing ball of product qualification rate, balance pipe integral structure ultrathick insulating
The technique of layer.
The object of the present invention is achieved like this：
One, mold clean：
The inside and outside portion of mould need to be carried out to clean to remove repeatedly to depollute using giant or dedicated cleaning equipment between mould
Thing, the mould after cleaning must ensure surfaces externally and internally cleanliness without any pollution thing；
Two, the detection of wet paperboard, prepare：
Wet paperboard is detected using X-ray machine, it is ensured that in the wet paperboard used during shaped piece production without metallic foreign body and
Pollutant；
Three, wet paperboard is cut：
The wet paperboard of correspondingly-sized is cut according to the specification of product, tears 1~2 layer of wet paperboard outer surface off, and ensures l Water Paper thickness
Degree meets that wet paperboard is required with finished product thickness than defined.
Four, wet paperboard immersion：
By the wet paperboard stripped tiling in the sink, soaking time 5-8min；
Soaked wet paperboard is taken out tiling on the table, with hand roller wet paperboard rolling, bubble is discharged, l Water Paper is scratched with hand
One end of plate, scratches out the overlap joint groove that width is 60-80 ㎜, and the outer peripheral thickness of overlap joint groove is the half of l Water Paper plate thickness,
L Water Paper plate surface is patted with deionized water and is fluffed；
Five, make at balance pipe and improving bud grafting：
Wet paperboard is surrounded into balance pipe one week, then to being handled at the overlap joint groove of wet paperboard, i.e., scratches wet paperboard with hand
The other end, equally scratches out the overlap joint groove that width is 60-80 ㎜, the overlap joint groove at wet paperboard both ends overlap after thickness
Degree is identical with the thickness of wet paperboard, then the wet paperboard lap of splice carries out half lap binding between 60-80mm with nylon bandage；
Three layers of binding；
Process of binding pays attention to lap-joint's groove direction, ensures that nylon bandage binding direction is consistent with groove lapping direction, clockwise
Direction is spirally bound from top to bottom.
Six, make at voltage equalizing ball and improving bud grafting：
Feeding, from light to heavy, moderately will firmly be patted according to the humidity of wet paperboard, wet paperboard is being pressed when patting wet paperboard
Surrounded one week on ball；Overlapping part at the overlapping part at wet paperboard both ends and R angles is pounded paste, then appropriateness is patted with hand
And press repeatedly, until the fiber of wet paperboard fully merges（Close slurry）, then with nylon bandage half lap binding is carried out, make nylon bandage
Wet paperboard is completely covered；Three layers of binding；
When nylon bandage winds the lower edge of voltage equalizing ball, opposite side is wound to from voltage equalizing ball side, coordinates personnel to pin at this time
Nylon bandage, then loops back to origination side lower edge by nylon bandage, and whole process will ensure that nylon bandage continues stress；
After covering first layer, the voltage equalizing ball of disjunctor, balance pipe are put into vacuum (-tight) housing and carry out vacuumizing dehydration, dewatering time is
10min, pulls down nylon bandage after dehydration, and second of covering is carried out in the way of the 5th step and the 6th step；Cover the second layer
When, the binding number of plies of nylon bandage is three layers, and the dewatering time in vacuum (-tight) housing is 15min；During overlays third layer, nylon bandage
The binding number of plies be four layers, the dewatering time in vacuum (-tight) housing is 20min；When covering the 4th layer, the binding number of plies of nylon bandage
For five layers, the dewatering time in vacuum (-tight) housing is 30min；When covering layer 5, the binding number of plies of nylon bandage is seven layers, true
Dewatering time in sky cover is 40min；When covering layer 6, the binding number of plies of nylon bandage is nine layers, de- in vacuum (-tight) housing
The water time is 50min；
A small amount of water is sprayed to nylon bandage after dehydration, nylon bandage is lashed with cardboard, can so improve the smooth of insulating layer outer surface
Degree, and the outer surface of insulating layer is formed reticulate pattern；
Then product is sent in baking room and sizing is dried, drying time is 7 days or so, and drying temperature is 120 DEG C；So
After take out product, after it is completely cooled down to room temperature, nylon bandage is extracted out, covering complete.
It is an advantage of the invention that：Bind and all carry out vacuum dehydration due to each layer, so moisture can leak out completely
Come, drying time can be reduced, air cavity will not be formed between each layer of insulating layer.In addition its technique is simple, and work efficiency is high, and product is qualified
Rate is high.
