Manufacturing process of colored glass
Glass is an amorphous inorganic nonmetallic material, which is generally made of a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, and a small amount of auxiliary raw materials are added. Its main components are silicon dioxide and other oxides. The chemical composition of ordinary glass is Na2SiO3, CaSiO3, SiO2 or Na2O · Cao · 6sio2, etc. the main component is silicate double salt, which is an amorphous solid with irregular structure. It is widely used in buildings to isolate wind and transmit light, and belongs to mixture. There are also colored glass that shows color by mixing oxides or salts of certain metals, and tempered glass made by physical or chemical methods.
With the continuous development of the manufacturer's production technology, there are also various new types of glass, which have more and stronger functions and gradually replace ordinary glass. For example, ordinary glass windows that can only transmit light and wind, after using laminated glass, have the function of noise reduction and heat insulation, which is more convenient and practical. We will briefly introduce the manufacturing process of colored glass in the following to let you know the advantages and disadvantages of colored glass
The colored glass mentioned here mainly refers to the deeply processed products of colored glass. The manufacturing process of the original colored glass sheet is introduced separately.
First of all, it is necessary to draw a small window sketch - usually a watercolor painting - for the customer's confirmation, and then draw a full-size pattern or base drawing to explain the shape and color of the glass and the position of the lead bar used to fix the glass. Then remove the pattern from the base drawing, place it on the colored window glass or white glass, and then cut the pattern. Next, an image may be drawn on a part of the glass and baked in the kiln to combine the pattern with the glass.
Then insert the glass into the lead bar slot (i.e. lead frame), and then weld the joint. The lead sealed glass is assembled in blocks for easy handling. Then, install each piece of glass on the iron fence or support frame of the window. The geometric pattern formed by the lead bar and bracket is part of the overall design of the window.
There are three kinds of common processes in the market today: welding wire, color painting and inlay. The metal strips used for inlay can be divided into zinc strip inlay, copper strip inlay and lead strip inlay! In addition, there are electroplating black bar inlay, electroplating white bar inlay, electroplating gold bar inlay and so on. You can understand that the same pattern can have different processes. If you don't really touch the product, you can't distinguish it carefully by looking at the picture. Of course, there are more processes that can make the same pattern. Each has its own advantages and disadvantages. It depends on your own needs and products
According to the actual demand, foreign customers usually have a very large demand for lead bars, and domestic customers are mainly zinc bars and copper bars.
What are the advantages and disadvantages of painted glass
There are two main types of painted glass, one is synthesized by using modern digital technology through industrial adhesive bonding, and the other is the traditional method of pure hand painting. It can be painted on colored glass or on colorless glass.
Use glass as a canvas, use special pigments, paint, and then burn at low temperature. The colors will not fall off, and the degree of goodness will be longer. There is no need to worry about acid and alkali corrosion, and it is also easy to clean. Customized, the size, color and pattern can be matched at will, which is safe and more personalized, not easy to be identical but also fast. Its advantages are simple operation and low price; The disadvantage is that it is easy to fade and does not last long.
