Description
Technical field
The present invention relates to a kind of canopy and the method for repairing crack of porthole.
Background technology
Its main component of organic glass is polymethyl methacrylate (PMMA), is a kind of exploitation important thermoplasticity earlier
Plastics.Organic glass surface is smooth, and intensity is high, and good corrosion resistance is moisture-proof, and chemical property is stablized, also have it is good it is heat-insulated, every
Audio fruit, thus it is widely used in every field.In terms of aviation, most of aircrafts using organic glass as canopy,
The components such as windscreen and porthole.In civilian, it is mainly used as lampshade, window of automobile, steamer etc. etc..Go out from angle safe to use
Hair, the damage of organic glass can bring very big harm, or even jeopardize the life security of pilot, driver.
Organic glass will produce different outer damages in application process, and inevitable, and common outer damage has
It scratches, rupture etc..When pmma material in aviation field in application, these damages can not only influence the whole outer of aircraft
It sees, can also reduce the transmitance of organic glass, the flight sight during pilot driver aircraft is interfered, to flight
Cause security risk.Currently, the major way repaired for the outer damage of organic glass is to be ground polishing to it
Machine finishing first removes the fragmented parts of glass surface to solve irregularities, then with soft with flat and hard bistrique
Soft air supported head removes grinding marks.Such method treated organic glass Surface haze increases, and finish reduces, wearability
It can decline, and the amount of grinding being machined is larger, and the thickness of organic glass can be made to reduce, its mechanical performance is caused to decline.It is aobvious
Right such method also the rapid-maintenance to aircraft cockpit and porthole and is not suitable for, while being adopted this method to canopy and porthole
It needs to dismantle when repairing, to substantially prolong the time of repair.
Invention content
The present invention is to solve the method for repairing crack of existing organic glass canopy and porthole to need from frame
Upper dismounting organic glass, extends maintenance time, and treated the reduction of organic glass finish, wear resistance decrease, machinery
The technical issues of performance declines, and the method for repairing crack of a kind of organic glass canopy and porthole is provided.
The organic glass canopy of the present invention and the method for repairing crack of porthole carry out according to the following steps：
One, organic glass of the washing with crackle removes surface blot；
Two, the polishing of sample：
When the crack depth of organic glass is less than or equal to 100 μm：
1., add with the waterproof abrasive paper of 600#~800# the crackle on organic glass to surface after water polishing cleaning to remove；
2., add with the waterproof abrasive paper of 1000#~3000# water polishing to remove organic glass 1min~10min after face crack,
Then the surface for adding water to continue to be polishing to organic glass with the waterproof abrasive paper of 4000#~5000# is smooth；
When the crack depth of organic glass is more than 100 μm and is less than 600 μm：
1., add with the waterproof abrasive paper of 400#~600# the crackle on organic glass to surface after water polishing cleaning to remove；
2., add with the waterproof abrasive paper of 800#~2000# water polishing to remove organic glass 1min~10min after face crack,
Then the surface for adding water to continue to be polishing to organic glass with the waterproof abrasive paper of 3000#~5000# is smooth；
When the crack depth of organic glass is more than or equal to 600 μm and is less than or equal to 1000 μm：
1., add with the waterproof abrasive paper of 150#~400# the crackle on organic glass to surface after water polishing cleaning to remove；
2., add with the waterproof abrasive paper of 800#~1000# water polishing to remove organic glass 1min~20min after face crack,
With the waterproof abrasive paper of 2000#~3000# add water continue polish 1min-10min, then with the waterproof abrasive paper of 4000#~5000# add water after
The continuous surface for being polishing to organic glass is smooth；
Three, the cleaning and drying of sample：
Ultrasonic power be 200W~400W under conditions of, the organic glass after step 2 is polished be sequentially placed into alcohol and
It is respectively washed 10min~15min in deionized water, then dries organic glass；
Four, liquid is repaired in sample surfaces spraying：
Liquid is repaired in the surface even application of organic glass 1 time~2 times；
Five, sample surfaces repair liquid solidification：
Spraying is repaired into the organic glass of liquid in room temperature and cures 5min~15min under conditions of avoid ultraviolet light direct projection,
Organic glass is heated to 30 DEG C~50 DEG C solidification 5min~10min again.
Step 4 repairs the C8130 headlight renovation agents that liquid is Wuhan Che Anchi automobile services Co., Ltd in the present invention.
Present invention employs a kind of simple and rapid methods to organic glass canopy and porthole surface different depth
Crackle repaired, first use different model waterproof abrasive paper carry out quickly polishing removal surface crackle, it can be achieved that organic
The in-situ immobilization of glass, and amount of grinding is reduced, improve raw sheet quality；Then spraying repairs liquid to increase the transmission of organic glass
Rate.Organic glass surface smoothness is good after such method is repaired, transmitance is high (87% or more), while the organic glass method work
Skill is easy to operate, at low cost, is suitble to emergent rapid-maintenance.
