S6 obtains electronic-grade glass by the glass fabric after shaping and drying after silane coupling agent impregnation
Cloth.
Specifically, the glass fabric after shaping and drying is impregnated through silane coupling agent using dipping tank 7 in this step
Processing.
It as depicted in figs. 1 and 2, further include having holding net in the process flow of vibration spun lacing fiber opening method of the present invention
Band 2, pick trough 4, pre- press pump 8, filter 9, multistage pressure pump 10 and control operating device 11.
For example and without limitation, the pick trough 4 can be a rectangular groove body, and main function is recycle-water
Pierce fluid；The spun lacing fluid includes the pure water that pure water pipe provides and recycling pure water.Further, it is set in the top of the pick trough 4
It is equipped with holding mesh belt 2.
The pre- press pump 8 is by piping connection pick trough 4, for the fluid in pick trough 4 to be sucked circulation line；Into one
Step, pre- press pump 8 are also connect by pipeline with filter 9, and the filter 9 is used to filter the spun lacing fluid recycled in pick trough 4
In impurity, to guarantee that vibration spun lacing fluid is clean, and make to vibrate spun lacing fluid and become reusable resource, while can be with
4 notch of pick trough is allowed to have certain suction, being allowed to faster will be in the fluid sucking pick trough on 2 surface of holding mesh belt.Preferably,
The frequency of use 2000Hz of pre- press pump 8.
The multistage pressure pump 10 is to provide operating pressure for the high-velocity flow of vibration spun lacing；Specifically, multistage pressure
Pump 10 can be by the fluid pressurized of the pre- suction line from wash water slot 4 of press pump 8, and provides the fluid of a steady pressure.
In the present invention, the control operating device 11 is not located in fluid circulating line, be placed in figure it is merely meant that this
Device and entirely recycle it is relevant, to control pre- press pump 8, multistage pressure pump 10 and vibrate spun lacing device 3 operation；Specifically
, it is responsible for pre- press pump 8, the unlatching of multistage pressure pump 10 and vibration spun lacing device 3 and stopping and the setting of running parameter.
For example and without limitation, which can be set in the side of vibration spun lacing device 3.
As shown in Fig. 3 a, Fig. 3 b and Fig. 3 c, vibration spun lacing device 3 of the present invention includes water jet device 31, eccentric wheel
32 and eccentric wheel-drive motor 33.Wherein, eccentric wheel-drive motor 33 is connect with eccentric wheel 32, and eccentric wheel 32 is fixed by pedestal
On water jet device 31.When work, eccentric wheel-drive motor 33 is rotated with movable eccentric wheel 32, and eccentric wheel 32 drives water jet dress
31 side-to-side vibrations are set, while water jet device 31 makes the fluid with certain steady pressure for pumping 10 by multistage pressure form ratio
More stable water jet, the water jet strike carry out fibrillation processing to it on glass fabric bundle surface.
Further, there is row's aperture under water jet device 31 of the present invention, after water flow is by 10 pressurization of multistage pressure pump,
The multiple water columns of row pattern are formed, water jet is constituted；Water jet of the present invention is small column water flow as a result, can be from top to bottom
Strike ties up side in glass fabric.
In a preferred embodiment, opening vibration spun lacing device 3 makes it with the 1000-2000Hz (frequency of this frequency converter
Rate, vibration spun lacing device pass through the frequency control eccentric revolving speed of frequency converter, and eccentric wheel can reach preferred revolving speed under this frequency)
Starting, and make the eccentric wheel 32 for vibrating spun lacing device 3 with the revolution of 900r/min-1500r/min or so work in the direction of the clock
Make；At this point, the side-to-side vibrations under the drive of eccentric wheel 32 of water jet device 31, and oscillation distances are 1cm or so, specifically be can be
0.8cm-1.2cm；Water jet device 31 itself is also 10kg/cm with pressure simultaneously2-50kg/cm2, aperture 0.1mm-0.3mm,
The high-speed jet that water temperature is 15 DEG C -80 DEG C, spun lacing pump frequency is 25Hz-50Hz works, to carry out to glass fabric
Vibrate the processing of spun lacing fibrillation.
In the present invention, the velocity of rotation of the rotational frequency control eccentric 32 of eccentric wheel-drive motor 33, eccentric wheel 32
Velocity of rotation control water jet device 31 Oscillation Amplitude, the rotational frequency of eccentric wheel-drive motor 33 is higher, eccentric wheel 32
Velocity of rotation it is faster, the side-to-side vibrations amplitude of water jet device 31 is also bigger.
(flow direction that arrow direction is spun lacing fluid) as shown in Figure 2, during vibrating spun lacing fibrillation, spun lacing fluid
It first passes through pre- press pump 8 and is sucked into filter 9, then be admitted to multistage pressure pump 10, and then vibration is squeezed by multistage pressure pump 10
In spun lacing device 3, and by the water jet of the vibration one group of double swerve of formation of spun lacing device 3, strike ties table in glass fabric
Uniform fibrillation processing is carried out in face of it, spun lacing fluid passes through holding mesh belt 2 again and is sucked into pick trough 4 later；Then, it repeats
Above-mentioned steps are to complete the fibrillation processing to glass fabric.
Further, such as Fig. 4 a and Fig. 4 b it is found that through the processed glass fibre of vibration spun lacing fiber opening method of the present invention
Cloth B has better uniformity compared with using the glass fabric A of non-vibration spun lacing fiber opening method processing.Because non-
It vibrates in spun lacing fibrillation treatment process (as shown in fig. 4 a), water column strike is total between water column and water column while cloth ties surface
Gap can be generated, causes some yarns that can not be hit by water column and arrives, and then cause fibrillation uneven；And in vibration spun lacing fibrillation processing
(as shown in Figure 4 b) in the process, water column can have the side-to-side vibrations of certain amplitude while hitting cloth bundle, and generate one group of vibration
Dynamic spun lacing keeps fibrillation more uniform so that water column be allow to hit on each glass fibre.
The present invention also provides a kind of electronic-grade glass fiber cloths, are obtained using vibration spun lacing fiber opening method above-mentioned.
