Features and application of curved tempered glass
The development of tempered glass originally dates back to the mid-17th century, when King Rhine discovered it, also known as toughened glass. After the tempered glass is broken, it is broken with small obtuse angle particles, which will not cause great harm to the human body.
After years of development, tempered glass technology has been fully promoted and popularized in the world, tempered glass began to be put into use in many fields, especially in the construction and automobile aspects of the fastest development, with people's development needs, curved tempered glass should also need to be produced.
The production method of curved tempered glass is to put the cut glass of good size (the glass that requires water jet cutting and drilling holes need do first), into the tempered heating furnace, heating to softening temperature, make the glass softening, placed in the radian of curved tempered glass mold using cold wind will its fast uniform cooling molding, can be made into curved tempered glass.
The surface of the tempered glass forms uniform compressive stress, while the interior forms tensile stress, which multiplies the surface strength of the glass and effectively improves the bending resistance and impact resistance of the glass, with a strength of four times that of float glass. When curved tempered glass breaks, it splits into small particles that are uniform, small and obtuse shape and not easy to hurt people, which is safety glass.
Curved tempered glass is widely used in daily life. Single pieces of low iron glass, color glass, coated glass and printing glass can be made into curved tempered glass, or combined products such as curved tempered insulating glass, curved tempered laminated glass and curved tempered laminated insulating glass. It is mainly used for interior and exterior decoration, light roof, sightseeing elevator, arched corridor, revolving door, curtain wall, etc.
The difference between curved tempered glass and hot bending glass
The processing method is different
Hot bending glass using hot bending furnace processing, at present, most glass processing plants use electric heating hot bending furnace, this hot bending furnace temperature control is convenient, easy to operate, do not pollute the glass, the quality of products and product consistency is high. The hot bending furnace can only process a piece of glass at once.
The curved tempered glass is made by bending the tempering furnace, heating the glass to the softening point and then placing it in a tuned mold, which is quickly and evenly cooled by hot pressing.
Different strength, hardness and safety performance
Curved tempered glass has been tempered, and hot bending glass is not tempered treatment, which is equivalent to ordinary glass. Therefore, the strength of curved tempered glass is 4 times that of hot bending glass. When the curved tempered glass is broken, it will also form small fragments at obtuse angles, which greatly reduces the harm to the human body and has higher safety. However, hot bending glass has not been tempered, so has poor safety performance.
The appearance shape is different
The appearance of curved tempered glass is arc-shaped, and the shape is limited; hot bending glass can be made in any shape.
