Prevention:
(1) Install glass spacers as required so that the weight of the glass can be supported to avoid deformation of the window sash. The glass mounted in the mullion should have two bearing pads below it, and the distance from the vertical edge of the glass is l/4 and not less than 150mm. The other direction should be set bit block, in order to fix the glass to ensure evenly around the gap.
(2) The glass spacer should use hard rubber with a hardness of 80 degrees Nah, and its width should be greater than the thickness of the supported glass. The length is not less than 25 mm, and the thickness is generally 2-6 mm.
(3) Before the glass is in place, check the position of the pad to prevent the pad from falling off due to impact and vibration. The position is inaccurate and the drainage hole is blocked.
(4) Strictly control the cutting size of the glass. The difference between the size of the glass and the size of the frame fan should be equal to the thickness of the two pads.
Glass installation loose, rubber seal off
The glass installation is not centered, the gap of the glass frame is uneven, the rubber seal is not close to the glass and the window frame, and the installation is not smooth. Hit the glass with your hand and let loose.
The reason for this situation:
(1) When installing the glass, the debris in the notch is not removed in time, so that the glass and the notch are not aligned.
(2) The gap between the glass and the glass notch is uneven, the rubber strip is in poor contact with the glass and the glass notch, and the glass notch protrudes, and the seal can be easily pulled off by hand.
(3) The rubber strip is not disconnected at the corner and is not glued.
Remedial measures:
(1)Before installing the glass, carefully remove the debris in the slot, such as mortar, brick, wooden block, etc., and carefully center the glass when it is placed to ensure that the gap on both sides is even and fixed in time to prevent collision and displacement. Deviation from the center of the slot.
(2) The rubber seal cannot be pulled too tightly and the length of the blanking is 2O-3Omm longer than the assembly length. The installation should be in place, the surface straight, and glass, glass notch close contact, so that the glass around the force. The rubber strips should be cut off at the corners and glued firmly at the disconnection.
(3) When the glass is sealed by sealant, the glass should be squeezed with a rubber strip or a rubber block to leave gaps in the plastic injection. The depth of the plastic injection should not be less than 5mm. Before the adhesive is cured, the glass should be kept from vibration. .
