Description
Technical field
The invention belongs to base plate glass manufacturing field, it is related to a kind of base plate glass production drainage plate and its construction method.
Background technique
For the base plate glass of flat panel display, for thickness between 0.3mm~1.0mm, it is in flat-panel monitor
One of critical component.FPD is high to the requirement of the optics of base plate glass, mechanical strength, thermal stability and surface smoothness,
Therefore it is even more important in the production process of base plate glass to quality and production stability control.
Overflow downdraw technique can shape the thin plate substrate glass of high quality, these thin plate substrate glass can be used for similar flat
A variety of devices of plate display.Overflow downdraw is the preferred technique for producing base plate glass used in flat-panel monitor,
Because technique thus can produce with the base plate glass produced by other methods compared with surface with more excellent flatness and smoothness
Base plate glass.
A kind of molding machine Refractory blocks of special shape for being commonly referred to as overflow brick are utilized in overflow downdraw, and glass metal is at this
It flows downward on overflow brick from both sides, and meets and forms single base plate glass in bottom.As shown in Figure 1, traditional at shape dress
Setting 100 includes an entrance 102, which receives glass metal 104, and glass metal 104 flows into a slot 106 (for example, weir 106),
Then it overflows, due to the power of gravity and the withdrawing roll for pulling glass metal 104, is fused together forward position two at a referred to as root 110
108a and 108b flow downward on side.Root 110 is both sides 108a assembled with 108b together with two of place and glass metal 104
Hereafter overflow wall pulls downward in conjunction with place and cools down glass metal to form a base plate glass 112.
The glass metal of edge needs to drain, it is therefore desirable to drainage plate be arranged, drainage plate effect is that reduction base plate glass plate is wide
Decaying and to the instable sensibility of flow, while can be to base plate glass side plate state (such as glass adhesion and side plate
Thickness) it is controlled.Base plate glass side plate state determines the stability of base plate glass traction drop-down, with base plate glass plate width ruler
Very little increase, edge bonding glass quality state are even more important.
Existing drainage plate curved surface be easy to cause the fairness of curved surface bad as made of several sections of surface joinings so that
The melt flow for flowing through drainage plate is unsmooth, to cause thin type substrate glass edge board status bad, be easy to cause hole and side
Portion's misalignment, meanwhile, cause base plate glass plate to change again greatly, technique is unstable, the warpage of product and stress poor quality.
