Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearer, below in conjunction with embodiment, to the present invention
It is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain the present invention, is not used to
Limit the present invention.
The embodiment provides the processing technique of a kind of mobile phone safety glass film, comprise the steps:
(1) glass-cutting that 0.2～.5mm is thick is become the glass membrane of certain specification, first glass membrane is carried out punching and
Trimming processes, and then carries out edging process；
Concrete, during cutting, the specification according to mobile phone writes a various sizes of glass membrane of one-tenth, then by carving machine pair
Punching in the setting position of glass membrane, predominantly matches with " boss's key ", front-facing camera, receiver etc., and trimming is then led
Four angles of glass membrane to be, cut into arc limit structure；Edging mainly passes through flat-grinding machine or other grinding machines to glass membrane
Carry out burr and antidamping processes, to increase surface and the edge smoothness of glass membrane, extend its service life.
(2) by step (1) process after glass membrane the pre-heat treatment 30～60 minutes, put into 400～420 after the pre-heat treatment
DEG C liquid potassium nitrate in 90～110 minutes, take out natural cooling；
Can arrange and add hot tank, be placed with in adding hot tank solution glass membrane is positioned over add hot tank in carry out the pre-heat treatment,
It is specially, in 30～60 minutes, glass membrane is heated to 280 DEG C by room temperature, then the glass membrane of 280 DEG C is positioned over
Cure process 90～110 minutes in the liquid potassium nitrate of 400～420 DEG C, can hardness as required and toughness set standing time
Putting, the hardness of the glass membrane of cure process time the longest formation is the biggest, toughness the best.
(3) it is carried out processing at 40～48 DEG C by the glass membrane after cooling；
Concrete, the present embodiment arranges three scrubbing grooves, five cleanings groove, pure water heating tanks.These three scrubbing grooves
Being mainly used in abatement processes, three scrubbing grooves are connected by the present embodiment respectively with three cartridge heaters, cartridge heater by pure water with wash
Wash agent and be heated to 45～48 DEG C, then drive pure water to be entered scrubbing groove with the mixed liquor circulation of detergent by cartridge heater by water pump
Return again in cartridge heater, thus in ensure that scrubbing groove, the temperature of mixed liquor is 45～48 DEG C, during abatement processes, will be fixed with many
The fixed mount of individual glass membrane is positioned in scrubbing groove, opens supersonic generator and mixed liquor in scrubbing groove is carried out ultrasonic place
Reason, the supersound process of the present embodiment mainly makes form multiple micro-bubble in pure water and vibrate, in vibrated by ultrasound wave
During increase and close, vibrated and closing course produce shock wave and the surface of glass membrane are carried out, with
Time by the glass membrane after ultrasonic Treatment, there is more preferable toughness.
During abatement processes, the fixed mount being fixed with multiple glass membrane is sequentially placed respectively in three scrubbing grooves, each
Place 2 minutes in scrubbing groove.Wherein, in the present embodiment scrubbing groove, the temperature of mixed liquor is preferably arranged to 48 DEG C.
During owing to first glass membrane is carried out abatement processes, glass membrane surface impurity is more, and cleaning difficulty is big, at head
Place more abluent in the secondary scrubbing groove carrying out sewage disposal, be specially pure water and abluent in first time abatement processes
Volume ratio is 100:3, and in second time and third time abatement processes, pure water is 100:1 with the volume ratio of abluent.Wherein, abluent
The conventional abluent bought for market.
Being cleaned after abatement processes processing, cleaning processes and is specially and will be fixed with the fixed mount of multiple glass membrane successively
Being positioned in the cleaning groove of five pure water being loaded with 40～42 DEG C, in each cleaning groove, standing time is 2 minutes, each cleaning
It is provided with supersonic generator in groove and carries out supersound process.
After cleaning has processed, glass membrane is slowly immersed in built with in the pure water heating tank of 90 DEG C of pure water, the most again
Slowly propose, make glass membrane be heated to 90 DEG C by the pure water of 90 DEG C by the pure water process of slowly turnover 90 DEG C, in order to after
Continuous drying, it is to avoid during drying, temperature sharply increases and causes glass membrane thermal expansion to crush.And, pure water heating tank is also provided with
Supersonic generator carries out supersound process.
In order to reduce the waste of pure water, five cleaning grooves and pure water heating tank can be sequentially connected with, and a cooling bath is set,
Pure water in pure water heating tank flows in cooling bath, is cooled to 40 DEG C and cleans in groove to entering one of them, then by wherein one
Individual cleaning groove enters in another cleaning groove, flows into last cleaning groove, and the inflow that pure water is between cleaning groove the most successively
Order and glass membrane are sequentially placed into the orders of five cleaning grooves and are reversed, thus ensure that glass membrane is more clean pure
Water cleans successively.
Wherein, in the cleaning groove of the present embodiment, the temperature of pure water is preferably arranged to 40 DEG C, in order to ensure stablizing of its temperature
Property, heater can be set on cleaning trench bottom or sidewall.
Corresponding, the frequency of the ultrasound wave that scrubbing groove, the supersonic generator cleaned in groove, heating tank send is
40KHZ, to ensure its cleaning performance.
(4) glass membrane after cleaning up is dried at 115～125 DEG C, carries out oiling and rubberizing processes.
Wherein, above-mentioned drying temperature is preferably 120 DEG C.After drying, after natural cooling, carry out oiling respectively by flush coater
Process with rubberizing.
Under the conditions of different parameters, ten groups of mobile phone safety glass films are processed respectively by the processing technique of the present embodiment, and by city
The ordinary glass film that field is bought is organized ten groups processed with the present embodiment as a comparison and is contrasted, shown in table specific as follows:
Table 1 (machined parameters)
Table 2 (reduced parameter)
Bending degree in the present embodiment table 2 is the angle of the mobile phone safety glass film one end opposite other end bending after processing
Degree, and from above-mentioned table 2, the mobile phone safety glass film using the present embodiment processing technique to produce substantially has bigger bending
Degree, i.e. the mobile phone safety glass film of the present embodiment has more preferable toughness, and it not only has preferable hardness and anti-crushing more
Good.
The detailed description of the invention of present invention described above, is not intended that limiting the scope of the present invention.Any basis
Various other that the technology design of the present invention is made change and deformation accordingly, should be included in the guarantor of the claims in the present invention
In the range of protecting.
