A kind of preparation method of ultra-clear glasses brick
Technical field
The invention belongs to building material technical field, be specifically related to a kind of preparation method of ultra-clear glasses brick.
Background technology
Plate glass is the glasswork of a kind of " class brick shape ", comprises the bulk material suppressed by colourless or coloured glass and with the block member of glass in surperficial glazing.Principal item has hollow glass block, solid glass brick, glass facing brick and glass mosaic tile (mosaic) etc.Hollow glass block is partly gone back high temperature training by two blocks of spill glass and is connect or form by adhesive bond, the cavity that inner formation is airtight.The hollow glass block welding method production is produced because its ultimate compression strength is high, be convenient to procedure and is widely used.
Hollow glass block has that surperficial brilliant fluorescent is clean, printing opacity and do not have an X-rayed, the advantage such as sound insulation, heat preservation compression resistance intensity are high, fire prevention, can be applicable to external wall or partition.Product internal surface has projection, recessed floral designs, can also can, all hook soft by light diffusion indoor everywhere by printing opacity.For partition, unique delicate fragrance; Be used for constructing external wall, attractive in appearance firm, daylighting is good; Especially night uniqueness " lamp decoration " effect, brilliant, magnificent mansion, makes people infatuated, is subject to the favor of many design masters.In recent years, along with the change of consumption concept, " whiteness " of glass becomes the problem that user more and more pays close attention to, and proposes requirements at the higher level to the light transmission of plate glass and tone stability.Plate glass thickness is generally more than 8cm, and its color generally presents partially bluish-green feature because of its iron content.
Ultra-clear glasses brick has the stable feature of high transmission rate, high whiteness, tone, has catered to the consumers demand of people, has become market new lover.Exploitation ultrawhite product, improving product class, captures high-end market, increases economic efficiency, thus the competitive power of enhancing enterprise in the same industry has important practical significance.
Summary of the invention
