In daily life, we often come into contact with various types of glass materials. In addition to traditional flat glass, there are glass materials with special properties such as ultra-white glass and borosilicate glass, as well as hollow glass and laminated glass. Common materials. In order to let everyone know more about the characteristics of curved steel and hot bending glass
Glass selection for duplex and spiral staircases can exclude flat tempered glass
The Mohs hardness of hot-bent glass and curved tempered glass is the same 6.8
The impact resistance of curved tempered glass is 2-5 times that of hot-bent glass, and the bending of steel is greater than or equal to 90 kg/cm 2. The hot bending is less than or equal to 45 kg/m 2 cm, which means that the bent steel has no hot bending and is easily broken. More extensive
Heat resistance stability: The molten lead liquid (327 ° C) was poured on glass at room temperature without breaking. The tempered glass was heated to 200 ° C and placed in 25 ° C water without breaking the glass.
Tempered hot bending glass
Performance: 1. Safety: When the qualified tempered glass is broken, the fragments are very small. The number of fragments in the 50mm×50mm area is not less than 40. The fragment cross section is basically perpendicular to the surface, and there is no sharp sharp corner. hurt.
2, impact strength: withstand 1040g steel ball from 1 meter high free fall impact is not broken.
3, bending strength: bending strength can reach 200Ma.
4. Optical properties: The optical properties of the glass do not change during the tempering process.
Uses: Widely used in construction, automobiles, ships, aircraft, instruments, instruments and furniture.
Standard for tempered glass: tempered glass: GB/T9963-1998 "tempered glass"
Curtain wall glass: GB/17841-1999 "Toughened and semi-tempered glass for curtain wall"
Heat-enhanced glass: Q/YH27-1999 "heat-enhanced glass"
