Cold bending and hot bending, how much do you know about curved glass?

I believe that everyone will not be unfamiliar with the material of glass. You can also see many office buildings, commercial buildings, and landmark buildings that use glass curtain walls when walking on the street. And with the development of design concept and technology, people's requirements for the installation of glass is no longer limited to the plane, curved glass came into being, and by many people's favor, in the indoor space is widely used in screen and partition, partition wall and other forms. Curved glass not only has the function of separating space, but also highlights the effect of artistic decoration, and the design choice is diversified. You can choose characteristic patterns or draw art paintings on the screen to show your personality and give people visual stimulation, fashion and beauty. The light transmittance of glass is used to create a delicate and noble atmosphere, full of art and sentiment; the glass surface can also be sandblasted and carved to highlight the overall design of the exquisite and design sense. The curved glass has a natural and beautiful arc, which can not only extend the visual effect of the space, but also the smooth arc can make the space more designed. Compared with the traditional plane, it breaks the curing thinking and creates a new and unique effect. The use of curved glass design has a soft sense and flow form, ripples, bumps and bends. These elements show the inherent strength of the material, giving people a higher level of beauty and style. Manufacturing method of curved glass The production method of curved glass can be divided into hot bending and cold bending. Hot bending technology has been used since the 19th century, but it was not widely used until the 1990 s. However, this process is still very expensive, and the logistics of transporting bent glass is also very complicated. About a decade ago, people developed an alternative technology, cold-bending glass. Cold bending technology has low cost, convenient transportation, and better geometric and visual quality than hot bending. Although it seems that cold bending technology has great advantages, it still has great limitations in practical use as a new technology. The application of cold-formed glass has strict requirements on the glass material, design team and construction team. The maximum warpage value needs to be strictly measured and controlled, and the residual stress should also be ensured within the controllable range. In the actual application process, it is necessary to go through strict design calculation, test verification and process control to ensure safety and reliability. glass hot bending Hot bending glass from the shape of the classification, can be divided into single bending, bending, bending three categories. For single bend glass, glass hot bending is relatively easy. Common hot bending glass are aquarium glass and counter glass. The main technical difficulties of bending glass are bending of straight edges and defects such as mold marks at corners. Such as spherical glass, turning arched profile, glass wash basin, etc., in the hot bending operation requires a high level of technology, the need to make accurate mold, professional hot bending furnace can be completed. Cold bending of glass The principle of glass cold bending is to use the flat glass itself has a certain elastic and bendable characteristics, the installation of artificial reasonable bending installation in place, through the bending and distortion of a number of flat glass to achieve the effect of fitting the curtain wall surface. The interior of the installed plate, including glass and profiles, has allowable internal stress. In the design process, the BIM system should be used to accurately simulate all plates and connection points and systematize the data, and all connection points should be accurately positioned during construction, so that the glass plates can be cold-bent and crimped with each other.

Behind the recent doubling of the number of home appliance glass buyers

Recently, the number of home appliance glass buyers has doubled, mainly concentrated in small appliances. As a sub-industry of the glass industry, the home appliance glass industry has gradually developed and grown with the application of glass in home appliances and the entry of various home appliances into thousands of households. With the continuous development of the economy, people's living standards have been greatly improved. The application of home appliance glass in daily life is becoming more and more extensive, and the application products are gradually diversified, such as fingerprint locks, induction cookers, health pots, air conditioners, refrigerators, microwave ovens, etc. At present, the home appliance glass industry is widely used, the technical requirements are also higher products are mainly for all kinds of low-temperature storage equipment (freezer, wine cabinet and refrigerator, etc.) supporting the glass door body and electronic touch panel and other deep-processed glass products. Low temperature storage equipment supporting the glass from the initial pure pursuit of beautiful, cheap, to the current appearance, function, energy saving, environmental protection and other functions and factors, and according to the end user's consumer demand for upgrading and continuous improvement. With the export of freezers, wine cabinets and refrigerators supporting the glass door body and the competition with foreign products, the relevant indicators of the glass door body are further in line with international standards, and the production level and product quality of the whole domestic industry are constantly improving.
