Abstract
The present invention provides a kind of TFT LCT glass substrate forming carry-over pinch rolls, carry-over pinch rolls roller core outer cladding high silica fiber layer, high silica fiber layer is used to contact and clamp glass plate.Wherein, its softening point of high silica fiber layer is 1500 DEG C~1700 DEG C.The present invention substitutes asbestos fibre material using high silica fiber, to realize the molding job stability of ultrathin glass and security of carry-over pinch rolls clamping liquid crystal substrate glass class, realizes and stablizes and improve the purpose of clamped shaping glass sheets quality.The invention also discloses the preparation methods of the TFT LCT glass substrate forming carry-over pinch rolls.
Description
Technical field
The invention belongs to the manufacture of TFT-LCD glass substrates and field shaping technique, more particularly to a kind of TFT-LCT glass bases
Sheet metal forming carry-over pinch rolls and preparation method thereof.
Background technology
In TFT-LCT glass substrate manufacturing processes, the carry-over pinch rolls of drop-down traction shaping glass sheets play clamping glass edges of boards
Portion, the effect for ensureing shaping glass sheets.
Carry-over pinch rolls external cladding material can be based on asbestos fibre (various metals such as iron content, magnesium ingredient), specifically to have following
Shortcoming：
1. use is with covering materials such as asbestos fibres, at 1000 DEG C, though thermal stability is higher, deformation easy to wear is wrapped
Cover that the frictional force of material surface is unstable, to the traction force malleable of glass plate, work persistence is poor, and the short cycle is needed to use
After replace.
2. use is with covering materials such as asbestos fibres, the dust-like object after abrasion, adherency is on a glass or contaminated equipment
Furnace body is not easy to be cleaned, remove.
3. use does not possess production security and the feature of environmental protection with covering materials such as asbestos fibres.
The content of the invention
It is an object of the invention to provide a kind of TFT-LCT glass substrate formings carry-over pinch rolls, use high silica fiber
Substitute asbestos fibre material, with realize carry-over pinch rolls clamping liquid crystal substrate glass class the molding job stability of ultrathin glass with
Security is realized and stablizes and improve the purpose of clamped shaping glass sheets quality.
The present invention is to be achieved through the following technical solutions：
A kind of TFT-LCT glass substrate formings carry-over pinch rolls, carry-over pinch rolls outer cladding high silica fiber, high silica fiber are used for
It contacts and clamps glass plate.
Preferably, its softening point of high silica fiber is 1500 DEG C~1700 DEG C.
The preparation method of the TFT-LCT glass substrate forming carry-over pinch rolls：High silica fiber makes slabbing, dehumidifying
It is sleeved on afterwards in laminated on carry-over pinch rolls roller core, pressurization sizing.
Preferably, after pressurization is shaped, the high silica fiber after sizing is processed into required size.
Compared with prior art, the present invention has technique effect beneficial below：
The present invention substitutes asbestos fibre material using high silica fiber, does finished product and is drawn for being clamped to glass plate.High silicon
Oxygen fiber is a kind of inorfil, there is higher thermal stability, and chemical stabilization, high temperature resistant, resistance to ablation, percent thermal shrinkage is low,
Job stability is high.When contacting at high temperature, clamping glass plate, the wear resistance of high silica fiber is higher than asbestos fibre,
When being processed into carry-over pinch rolls, density of texture, case hardness can reach necessary requirement, can guarantee that work persistence is strong.High silica is fine
Tie up it is safe to use, it is more environmentally friendly.High silica fiber dust adhesion is also easy to cleaning removal after glass pane surface.
Description of the drawings
Fig. 1 is a kind of TFT-LCT glass substrate formings carry-over pinch rolls operating diagram provided by the invention.
Wherein, 1 is high silica fiber layer, and 2 be carry-over pinch rolls roller core, and 3 be glass substrate.
Specific embodiment
With reference to specific embodiment, the present invention is described in further detail, it is described be explanation of the invention and
It is not to limit.
As shown in Figure 1, the present invention provides a kind of TFT-LCT glass substrate formings carry-over pinch rolls, including two groups of carry-over pinch rolls rollers
Core 2 and the high silica fiber layer 1 being coated on outside carry-over pinch rolls roller core 2.Two groups of high silica fiber layers 1 for clamp 3 edge of glass base,
Ensure that glass base 3 is molded.
High silica fiber substitutes asbestos fibre material, its main feature is that：High silica fiber is a kind of inorfil, softening point
For 1500 DEG C~1700 DEG C, there is higher thermal stability (carry-over pinch rolls of clamping glass are generally operational at 1000 DEG C).Its chemistry
Property stablize, high temperature resistant, resistance to ablation, percent thermal shrinkage is low, and job stability is high.When contacting at high temperature, clamping glass plate, high silica
The wear resistance of fiber is higher than asbestos fibre, when being processed into carry-over pinch rolls, required for density of texture, case hardness can reach
It asks, can guarantee that work persistence is strong.High silica fiber is safe to use, more environmentally friendly.High silica fiber dust adhesion is in glass
After plate surface, cleaning removal is also easy to.
The preparation method of high silica fiber layer 1 is：High silica fiber is made into slabbing, is in after dehumidifying at a certain temperature
Laminated is sleeved on carry-over pinch rolls roller core 2, and pressurization sizing is reprocessed into required size, does finished product for being led to glass plate clamping
Draw.Wherein, high silica fiber contacts and clamps glass plate.
