Emergency method of folding safety hammer Edit this paragraph: a closed chamber in the auxiliary escape tool. It is usually installed in a closed compartment cars and other content easily accessible to the place, the car in the event of fire or a car fell into the water and other emergency situations, you can easily remove the door and smashed windows to escape successfully. Uses: mainly used for smashing glass in an emergency escape glass with a hammer handle tail blade for cutting the seat belt to escape. Scope: Mainly used for buses, passenger vehicles, trains and other vehicles configuration. Use: safety hammer mainly using its conical tip, the tip is small because the contact area, so when the time with a hammer Za Boli, the contact point of the glass pressure (not pressure 12mm tempered glass, but the unit area on The pressure) is quite large, this is somewhat similar with the principles of thumbtacks glass, film can easily be punctured glass factory, and make the car glass at the point under great external force and a slight crack, and for glass cracking, it means a little bit of stress distribution inside the glass block has been destroyed, resulting in countless spider web-like cracks in an instant, then just gently hit with a hammer and then a few will be able to get rid of the glass fragments . In addition, the middle part of the glass is the most solid, corners and edges are the weakest. The best way is to use safety glass hammer edges and corners, especially the middle of the top edge of the glass where once the glass has cracked, it is easy to block smashed. Flexible glass is much larger than ordinary glass, a 1200mm × 350mm × 6mm tempered glass, can occur by the force of the deflection of up to 100mm, when the external force is removed, still restitution, but there can be only ordinary glass bending a few millimeters. Good thermal stability, thermal shock when the subject, less prone to burst is another characteristic of tempered glass. This is because stress can offset part of the glass so that the tensile stress generated due to thermal shock. Tempered glass thermal shock, the maximum safe operating temperature of 288 ℃, can withstand 204 ℃ of temperature changes. 88 tempered glass, glass sunshine, Yaohui specializing in the production (Views) provided by Jinan Glass Co., Ltd.
