Detailed description of the invention
The invention provides a kind of built on stilts mount height device part skeleton filled-type reinforcement means, adopt hole-opening foaming skeleton filling support pocket part space, use reinforced glue water infiltration foaming skeleton, foam skeleton adsorption reinforcing glue.After the foaming skeleton of absorption glue solidifies, it is filled with the built on stilts frame high-voidage of device, and shows the adhesive strength after glue curing.The method is easy to operate, lightweight compared with the bonding reinforcing of colloid, will not pollute printed board because of glue trickling, serve again the purpose of bonding reinforcing.Mainly solve glue and be difficult to fill open space, the problem that built on stilts mount height device part reinforces difficulty.It is characterized in that: to open space filling-foam skeleton, inject in skeleton and reinforce glue, after glue curing, show strengthening characteristic.
Foaming the adopted material of skeleton is: based on plastics (PE), the open-celled structure expanded material of the aromatic amides polymeric network correction by running through, coefficient of foaming is between 10-30 times, and density is 33-100KG/m3；Disperse and the macromolecular material compound of more uniform pore.
Reinforcing the glue viscosity range of choice wide, can be selected for viscosity at 1500-3000cps acrylic component, for heat cured electronic pastes, solidification temperature is room temperature to 125 DEG C solidification, has adhesive property with foaming skeleton.
Foaming skeleton cutting size is with packing space for benchmark, and because foaming skeleton elasticity is relatively big, it is low to cut out size precision prescribed, and when cutting out, relatively the packing space length of side has more 2-4mm, is tolerance interval, and filling with the skeleton that foams completely needs packing space.
With reinforced glue water infiltration foaming skeleton, foaming skeleton is added glue and can adopt glue injection machine, the artificial mode brushed, certainly infiltrate, all can reach the construction requirement of infiltration foaming skeleton.
Foaming skeleton from as open-celled structure, runs through between foaming materials hole mutually, for the material of a kind of hole framework, is conducive to reinforcing absorption and the infiltration of glue.
Foaming skeleton is material self color, is not added with pigment, yellowish white, it is simple to identify reinforced glue water infiltration region.
Reinforce the color of glue, have notable difference with the color of framework material, can need to add stain reinforcing glue, it is simple to glue injects can differentiate when foaming skeleton and whether infiltrates completely.
The thermosetting performance of glue, normal temperature solidified, it is possible under the middle temperature environment being not more than 150 DEG C, to carry out heat cure.
The compression ratio filling skeleton should at 1.1-1.5.
The instrument perfusions such as glue injection machine can be used, it is possible to adopt the capillarity of framework material micropore to carry out self-priming infiltration.
Below in conjunction with accompanying drawing, built on stilts mount height device part skeleton filled-type reinforcement means provided by the present invention is described in detail:
Embodiment one:
Referring to Fig. 1, being the bonding reinforcing process schematic diagram to certain small-sized built on stilts mount height device part, its concrete reinforcing process is:
1, according to the space such as Fig. 1 a that need to carry out skeleton filling reinforcing device, measurement, 20 times of coefficient of foaming, density 50KG/m are selected3, the polyethylene foams of 6mm thickness, the 6mm being cut out adapting with capacitive bottom space is high, 4mm width, the filling skeleton of 5mm length.
2, foaming skeleton tweezers are clamped, compress, send into device and need packing space, such as Fig. 1 b, it is determined that the foaming skeleton cut out fills full bottom device space.
3, after filling the space completely need to filled, the acrylic component electronic pastes selecting viscosity to be 1700cps, adopt glue injection machine infiltration foaming skeleton, such as Fig. 1 c.
4, after infiltration, room temperature stands 12 hours to reinforced glue water cure, such as Fig. 1 d.
Embodiment two:
Referring to Fig. 2, it is that its concrete reinforcing process is to memory bar reinforcing process schematic diagram bonding with ETX module employing foaming skeleton:
1, in certain computer CPU assembly, memory bar and ETX need to insert draw-in groove and assemble, and memory bar relies on jump ring to be fastened on computer motherboard；There is, in complicated mechanical application environment, loosening grade for unreliable factor in existing jump ring, and memory bar is directly carried out bonding with mainboard or jump ring by the electronics glue being generally adopted with viscosity is bigger for solving problems at present, such as Fig. 2 a；After this kind of method is directly bonding, when electronics glue is bonding, pollute printed board assembly, and because of the bigger glue of direct bonding employing rigidity, Stress Release is big, and makes maintainability decline, it is impossible to meet production development needs.
2, the reinforcing of this product memory bar is adopted foaming skeleton filling mode, according to memory bar lower space, such as Fig. 2 b；Select 15 times of coefficient of foaming, density 67KG/m3, the polyethylene foams of 10mm thickness, the 12mm being cut out adapting with capacitive bottom space is high, 15mm width, the filling skeleton of 40mm length.
3, foaming skeleton is carried out trial assembly with memory bar, ETX, after determining foaming skeleton riding position, after being 2600cps acrylic component reinforced glue water infiltration by viscosity bottom foaming skeleton, fix riding position, reinforcing glue is filled to foaming skeleton again, such as Fig. 2 c so that it is fully infiltrate with glue injection machine, memory bar is installed, it is ensured that the foaming skeleton after infiltration and memory bar, ETX fully in contact with.This kind of method, reinforces glue and is completely filled skeleton absorption, will not trickle and pollute；Secondly bond area is big, adds solidity anti-seismic performance good；Because of foaming skeleton pore space structure, Stress Release is little and readily accessible with maintenance.
4, after memory bar and ETX installation, room temperature stands 12 hours to reinforced glue water cure, completes the reinforcing of memory bar.
Embodiment three:
Referring to Fig. 3, being adopt foaming skeleton to fill the structural representation reinforcing transformer coil, its concrete reinforcing process is:
1, certain type product transformer coil is hollow structure, such as Fig. 3 a, coil use procedure is avoided severe mechanical environment coil is caused damage, the method being generally adopted casting glue landfill is reinforced, this burying method is bad to coil heat radiation, easily cause that coil is overheated to be burnt, and coil has been had been out maintainability.
2, the method adopting foaming skeleton to fill, according to coil interior diameter, selects 10 times of coefficient of foaming, density 100KG/m3, the polyethylene foams of 6mm thickness, cut out diameter 4mm, the cylinder of high 6mm.Bottom 4mm thickness foaming skeleton is cut out the identical diameter of coil outside dimension and is filled base.
3, selecting viscosity is that 2800cps acrylic component reinforces glue, and because need to providing certain bracing reinforcement power to coil from internal diameter, selected foaming skeleton hardness, density are bigger；Reinforce glue viscosity to improve, if first filling skeleton, being difficult on product with the bigger reinforcing glue complete wetting of viscosity, for ensureing product construction quality, therefore need first foaming skeleton to be infiltrated in advance, such as Fig. 3 b, the filling skeleton infiltrated crammed in coil in footpath with tweezers again, such as Fig. 3 c.
4, after end-of-fill, room temperature stands 12 hours to reinforced glue water cure, completes the foaming skeleton reinforcing to transformator, such as Fig. 3 d.The pore space structure run through in foaming skeleton in the method is easy to heat radiation, solves colloid and directly fills the problem that transformator causes transformator heat dispersion to decline；Simultaneously as foaming skeleton is easy to remove and maintenance, the difficulty that after also solving colloid landfill, transformator cannot keep in repair.
