Can float glass be hot bent

hot bending glass is secondary processed by using flat glass (including float glass). And float glass is the base material that can be used to process tempered glass

attachment:

hot bending glass is a curved glass made by heating, bending and softening high-quality glass, forming in a mold, and then annealing to meet the high-quality needs of modern buildings. Beautiful style and smooth lines. It breaks through the singleness of flat glass and is more flexible and diverse in use to achieve comprehensive, harmonious and sustainable development. Suitable for fish tanks. dining table. Balcony. counter. The cosmetics counter. Special requirements for different shapes of hot bending TV cabinet, door, window, ceiling, curtain wall, etc. It can produce hollow, sandwich and other composite hot bending glass products, which can be customized according to the requirements of customers

it appears more and more frequently in some high-end decoration, which requires reservation, and there is no stock. The order time is about 2 days

hot bending glass is a curved glass made by heating and softening flat glass, forming in a mold, and then annealing. Hot bending glass is generally processed in an electric furnace. There are two types of hot bending Furnaces: continuous and intermittent. The continuous hot bending furnace generally has 5~6 rooms and 11~13 stations, and a finished product can be produced in about dozens of minutes. The intermittent hot bending furnace generally has only one room, and the heating, forming and annealing are completed in one room. The processing cycle takes several hours to one or twenty hours, which is suitable for making small batches of super large hot bending glass

technical description

hot bending glass can be divided into three categories: single bending, bending and composite bending

for building glass with a single bend, glass hot bending is relatively easy. However, many manufacturers often fail to match the mold well at the curved edge of the products about 150mm away from the straight edge, and some of them exceed the standard requirements, causing difficulties in installation. To solve this problem, first of all, the electric heating layout of the hot bending furnace should be reasonable, which can realize local heating, and the placement direction of the products should be consistent with the direction of the electric heating wire

the common hot bending glass is aquarium glass and counter glass. The biggest technical difficulty of bending glass is that the straight edge is bent and the corner is prone to mold marks and other defects. Therefore, curved glass is also very common, such as spherical glass, curved arched outline, glass wash basin, etc. this kind of glass requires a high technical level in hot bending operation, making accurate molds, and some require a professional hot bending furnace to complete

what is the difference between ordinary flat glass and float glass

a: both ordinary flat glass and float glass are flat glass. Only the production process and quality are different

ordinary flat glass is a transparent and colorless flat glass produced by using quartz sandstone powder, silica sand, potassium fossils, soda ash, mirabilite and other raw materials in a certain proportion, melting in a furnace at high temperature, and using vertical lead-up method, flat drawing method, calendering method. According to the appearance quality, ordinary flat glass is divided into three categories: special products, first-class products and second-class products. According to the thickness, it is divided into five types: 2, 3, 4, 5 and 6mm

b: float glass is a transparent and colorless flat glass made of sea sand, quartz sandstone powder, soda ash, dolomite and other raw materials in a certain proportion. After melting at high temperature in the furnace, the liquid glass flows continuously from the tank furnace to the metal surface and floats on the metal surface. It is spread into a glass belt with uniform thickness and polished by fire. After cooling and hardening, it is separated from the liquid metal, and then annealed and cut. The glass surface is particularly flat and smooth, the thickness is very uniform, and the optical distortion is very small

according to the appearance quality, float glass is divided into three categories: excellent products, first-class products, and special products used in laboratory machine fixtures

according to the thickness, it is divided into seven types: 3, 4, 5, 6, 8, 10 and 12mm

c: the appearance quality grade of ordinary flat glass is determined according to the number of defects such as wavy bars, bubbles, scratches, sand particles, pimples, and lines. The appearance quality grade of float glass is based on optical deformation, bubbles, inclusions, scratches, some frequently used experimental skills, or the number of defects such as lines and fog spots that we need to master. The desktop database is adopted; Query module

d: ordinary glass, emerald green, fragile, low transparency, easy to age and deform under rain exposure

float glass, transparent float glass is made of glass paste entering the tin bath through the control gate, floating on the surface of molten tin due to gravity and its own surface tension, and then entering the Xu cold bath, so that both sides of the glass are smooth and uniform, and the ripple disappears. Dark green, smooth surface without ripple, good perspective and certain toughness

e: the production process of float glass is different from that of ordinary glass. The advantage is that the surface is hard, smooth and flat. The color of float glass is different from that of ordinary glass when viewed from the side. It turns white, and the object is not distorted after reflection, but generally has water texture deformation
