Abstract
The present invention discloses the production process of heat resistant fireproof super strong tempering glass. the tempering glass will not burst up at 1000 deg.c and has high impact strength, and a 5x5 cm area will be crushed into over 400 grains. it is produced in a common tempering furnace and through quick cooling the upper and lowre surfaces of glass plate with strengthened blower pressure, reducing the thickness of tension stress layer while increasing the thickness of pressure stress layer.
Description
Technical field
The invention relates to the method for manufacturing of heat resistant fire-proof super strong safety tempering glass, in particular, the present invention utilizes common annealing furnace, uses new Technology to manufacture heat resistant fire-proof super strong safety tempering glass.
Background technology
Common toughened safety glass plate is that sheet glass is heated in annealing furnace near the cooling of drying rapidly again behind the softening temperature, produces compressive stress layer in the upper and lower surface of sheet glass, thereby produces shatter proof glass.The sheet glass of different thickness is adding man-hour, adopts different blast to the upper and lower surface of the sheet glass chilling of drying rapidly.The thickness that the common tempering glass pane upper and lower surface of producing produces stressor layers is about the sixth of sheet thickness.When sheet glass was broken, the monolithic glass plate all was broken into cellular obtuse angle small-particle, and the crushed particles quantity in 5cm * 5cm area is about 40～50.The physical strength of common tempering glass pane is about 3 times of ordinary plate glass.Common tempering glass pane does not have fire-proof function, can burst about 6～8 minutes after being subjected to flame impingement.
Summary of the invention
The present invention utilizes common annealing furnace, when the sheet glass upper and lower surface of different thickness is dried chilling rapidly, strengthens the pressure of blowing, and the amount that its blast increases is to produce about 4～20 times of the common tempering glass pane of different thickness pressure in the past.Utilize new production technology can increase substantially the thickness of sheet glass upper and lower surface compressive stress layer, reduce the thickness of inside of glass plate tension stress layer.The thickness of the superpower toughened safety glass upper and lower surface of the heat resistant fire-proof compressive stress layer that the new technology condition of employing the present invention is produced is respectively more than or equal to about 1/2nd of sheet thickness.When meeting fire, the superpower toughened safety glass of the heat resistant fire-proof of the technology condition production that employing the present invention is new under 1000 ℃ of high temperature, can adhere to not bursting in 90 minutes.Its resistance to impact shock is more than 1 times of common toughened glass, and when sheet glass was broken, the monolithic glass plate all was broken into cellular obtuse angle small-particle, and the crushed particles quantity in 5cm * 5cm area is more than 400.
Description of drawings
Illustrate the stress diagram of the superpower toughened safety glass of heat resistant fire-proof of the present invention
Embodiment
Below in conjunction with accompanying drawing technological principle of the present invention is described further.
The size that glass pane surface produces stressor layers depends on:
1, the initial temperature of refrigerative speed and tempering;
2,, between the surface of glass and inside, produce enough temperature difference at cooling stages;
3, strengthen the rising property of heat of glass and the density variation that cooling produces;
For this reason, improve the impact resistance of toughened glass, will produce bigger stress in glass pane surface.Sheet glass under the room temperature is sent in the process furnace, made the temperature of sheet glass move closer to tempering blowing temperature, in the temperature uphill process, the glass pane surface temperature is than inside of glass plate temperature height, the stress that this moment, sheet glass produced, the surface is a stress, inside is tension stress.Sheet glass enters cooling section from process furnace, at the cooling stages of sheet glass, glass pane surface is applied rapidly than producing the upper and lower surface of common tempered safety glass greater than 4 to 20 times blast winding-up sheet glass, carries out quick cooling.The glass pane surface cooling is faster than inside, at short notice, will produce the bigger temperature difference in glass pane surface and inside, thereby can increase substantially the thickness of sheet glass 1 bearing stress layer 2, reduces the thickness of sheet glass 1 inner tension stress layer 3.When the thickness of sheet glass 1 upper and lower surface compressive stress layers 2 reach more than or equal to sheet glass 1 thickness 1/2nd the time, under 1000 ℃ of high temperature, can adhere to not bursting in 90 minutes when the superpower toughened safety glass of the heat resistant fire-proof of being produced is met fire.Its resistance to impact shock is more than 1 times of common toughened glass, and the crushed particles quantity in 5cm * 5cm area is more than 400.
Embodiment 1:
When carrying out the production of 12mm thickness glass slab, sheet glass enters cooling section from process furnace, at the cooling stages of sheet glass, blast is brought up to 260mmAq by 12mmAq, to the cooling of drying rapidly of sheet glass upper and lower surface, produce the superpower toughened safety glass of heat resistant fire-proof.
Embodiment 2:
When carrying out the production of 15mm thickness glass slab, sheet glass enters cooling section from process furnace, at the cooling stages of sheet glass, blast is brought up to 200mmAq by 5mmAq, to the cooling of drying rapidly of sheet glass upper and lower surface, produces the superpower toughened safety glass of heat resistant fire-proof.
