Description
Technical field
The present invention relates to a kind of repair technology of Glass fabre reinforced plastic water tank crackle, belong to the technical field of metallurgical equipment.
Background technology
At present, the cooling circulation water tank used by the small-sized smelting equipment such as domestic vacuum drying oven, intermediate frequency furnace, adopts smc glass mostly
Glass steel combination water tank, it is assembled by the smc moulded glass steel veneer of overall high-quality, and smc molding veneer is using tree
Fat, glass fiber cloth, through High Temperature High Pressure, mechanical compaction forms, and Glass fabre reinforced plastic water tank by long-term use, easily produces suddenly and splits
Stricture of vagina, caused by reason is mainly the comprehensive function of aging and internal stress of reinforced plastic plate.After crackle produces suddenly, cooling circulating water
Fast leak, causes the smelting equipments such as vacuum drying oven, intermediate frequency furnace to stop production.Therefore, existing Glass fabre reinforced plastic water tank is because cracking needs
Change, original old Glass fabre reinforced plastic water tank removed, the Glass fabre reinforced plastic water tank more renewing, implementation cost is high, wastes time and energy, the cycle is long,
Impact produces.
Cn101890816a discloses a kind of method for repairing and mending of glass fiber reinforced plastics product, and it comprises the following steps: (1) judges glass
The defect of steel part expands the need of artificial, entering step 2 if necessary, if do not needed, leaping to step 3；
(2) cut open scrape at defect and its peripheral position so that at defect expand；(3) with powder and the strength of prefabricated glass-reinforced plastic material
Binding agent is alternately smeared at defect, until the mixture of the powder of glass-reinforced plastic material and strength adhesive fills up and exuberant defect
Place；(4) part at the mixture overflow defect of the finishing powder of glass-reinforced plastic material and strength adhesive is so that glass steel
The exterior contour of product meets design requirement；(5) smear white oil outside at the defect trimming.But, the method is only applicable to glass
The preparation of glass steel part, processing, the defect causing in installation process.The repairing of the crackle using rear generation can not be used for.
Content of the invention
For above technical deficiency, the present invention relates to a kind of repair technology of Glass fabre reinforced plastic water tank crackle.
Term illustrates:

Press polish layer, until exposing ground floor glass fiber cloth, boring fabrication hole in the plate face of the destination county of crackle, wiping clean polishing table
Face；
(2) cutting metal screen is a piece of and polishes totally, cutting glass fiber cloth 4-6 piece, and cutting area at least can cover
Lid crackle occupied area, glass fiber cloth area ground floor is minimum, is successively incremented by, metal screen and third layer glass fiber
Cloth size is identical；
(3) prepare resin binder, by following components mix homogeneously by weight ratio:
(4) resin binder of step (3) is uniformly scratched one layer in crack site with putty scraper plate, then paste first
Layer glass fiber cloth, strikes off compacting with putty scraper plate；One layer of resin binder is scratched on ground floor glass fiber cloth again,
Paste second layer glass fiber cloth, continue to paste one layer of glass fiber cloth operation by one layer of resin binder, paste the 3rd
Paste layer of metal filter screen during layer glass fiber cloth simultaneously, continue to paste one layer of glass fiber cloth by one layer of resin binder
Operation, until the 4th～6 layer of glass fiber cloth is pasted and finished, scratches one layer on the glass fiber cloth of that layer last again
Resin binder, solidifies 20-24 hour, and repairing completes.
After repairing finishes, water tank is cleaned out and fills water, can come into operation.
In resin binder described in step (3) of the present invention, 191# unsaturated-resin is major ingredient, and methyl ethyl ketone peroxide is solid
Agent, cobalt naphthenate is accelerator, and filler made by Pulvis Talci.Filler made by further preferred 325 mesh Pulvis Talci.
According to currently preferred, described glass fabric thickness 0.2 ± 0.05mm.
It is stainless steel filtering net according to currently preferred, described metal screen；Further preferably 80-120 mesh metal filter
Net, thickness 0.2 ± 0.05mm.
According to currently preferred, it is to be polished with angle grinder clamping emery disc to crack site polishing in step (1)；Institute
The angle grinder stated is Bosch tws6000, power 620w, rotating speed 11000r/min.Described emery disc is BAIYE chip polishing sand disk,
Specification is 100x16mm (a diameter of 100mm of emery disc, a diameter of 16mm of installing hole).
According to currently preferred, the aperture boring fabrication hole described in step (1) is φ 3-5mm.When one end of crackle is whole
When point is in water tank corner, only bore a fabrication hole in the other end crackle terminal away from water tank corner.
According to currently preferred, cutting metal screen tinsmith snips in step (2).
According to currently preferred, the width of the putty scraper plate described in step (4) is 160-170mm.
According to currently preferred, the thickness that in step (4), resin binder scratches one layer is 0.5-0.8mm.
According to currently preferred, the weight of water tank bottom Crack Repairing resin binder is: 191# insatiable hunger

Be 90mm and width be 30mm.
Crack site is polished with angle grinder clamping emery disc, crackle occurs on one of reinforced plastic plate, glues
Two verticals need to be pasted simultaneously during patch, sticking veneer b3 and its sticking veneer b5 of adjoining vertical surface that polishing corner crack is located,
Polishing area is sufficiently large, and grinding depth will remove press polish layer, till exposing ground floor glass fiber cloth.Away from corner
Crackle one end terminal bore fabrication hole b4, aperture is φ 4mm, wipes clean polishing surface with dry cloth.
A piece of with tinsmith snips cutting metal screen, with shears cutting glass fiber cloth 5, cutting area splits according to corner
Depending on the adjacent two vertical b3 of stricture of vagina and b5 occupied area size, b3 a size of 90mm × 40mm, b5 a size of 40mm × 40mm；Glass
Glass silk fiber cloth ground floor minimum (110mm × 60mm), is successively incremented by (periphery extends out 10mm), and layer 5 is maximum, metal screen
Occupy third layer.Polish after metal screen cutting clean, needed metal screen 90-degree bent according to repairing.
The weight of resin binder: 100 parts of 191# unsaturated-resin, 2 parts of methyl ethyl ketone peroxide, cobalt naphthenate 2
Part, 325 25 parts of mesh Pulvis Talci；Pour in plastics keg, stirred with electric hand drill clamping agitator.
Using handss paste technique, personnel enter inside Glass fabre reinforced plastic water tank, in adjacent two verticals of corner crack, use putty respectively
Scraper plate uniformly scratches one layer of resin binder, and thickness is about 0.7mm, then pastes one layer of glass fiber cloth and covers crackle and prolong
Extend adjoining vertical surface, strike off compacting with putty scraper plate；One layer of resin binder is scratched on ground floor glass fiber cloth again,
Method continues like this, during third layer, pastes metal screen, after five layers of glass fiber cloth paste List, strike off, be compacted after, also
With putty scraper plate, resin binder need to be scratched on last layer of glass fiber cloth, the resin binder thickness of each layer is equal,
The gross thickness of repair layer is about 4.7mm.After repairing finishes 24 hours, water tank is cleaned out and fills water, can come into operation.
Embodiment 3, Glass fabre reinforced plastic water tank crackle produce in side, such as Fig. 3, and the repair technology step of crackle is as follows:
