Q:What material can not be sprayed on the glass?
If you want to spray characters on the glass, it is impossible to follow the glass unless it is frosted. If you really want to spray words on the glass, you can go directly to the print shop, do the word, and then stick it up.
Q:What are the production processes and raw materials of float glass?
Float glass production process refers to the glass liquid in molten metal floating on the surface of the flat glass production process. The production process of float glass is to select the raw material needed for the production of glass according to the designed glass composition, and weigh various raw materials according to the designed material, and then prepare the mixture by mixing.
Q:What kind of material is the glass made of? Is the price relative to the quality?
The main constituents of the glass are calcium silicate, sodium silicate and silicaExpensive and not expensive must be related to quality (at least with impurities)
Q:What are the raw materials for making glass?
Sandstone fused glass has a bright luster, and has a good transparency, acid resistance and mechanical strength.
Q:What are the ingredients of photovoltaic solar glass? What's the function of each?
Furthermore the limestone calcium carbonate and Magnesium Oxide, whose main role is to adjust the viscosity of the glass in a suitable value, so that the glass forming time is shorter or longer, in order to meet the requirements of molding; also the introduction of alumina materials, improve the physical and chemical properties of glass, such as strength, chemical stability, etc.;
Q:Why are most of the chemical instruments made from glass?
Of course, the glass is colorless and transparent is also very important, the front of some people said that the glass is cheap, I would like to deny, in fact, this glass is not often in general glass, high temperature, the cost is much higher than that
Q:The difference between natural crystal and crystal glass, merits and demerits!
Crystal glass according to PBO (lead oxide) content is divided into high (24%PBO and above), medium (18%PBO), low (12%-16%PBO) three grades. Grading standards are similar to gold. International standard crystal glass is 24%PBO, so merchants will also call this class "24K"". If you go to buy, say some similar "jargon", the other party will feel that you are more adept, encountered illegal businesses, nor dare to fool you.
Q:Glass factory raw materials specific to do?
The glass is the main component in the manufacturing process of quartz sand, quartz sand is combined with other chemical materials at high temperature (1300 degrees Celsius) crystallized after firing the cooling of the body, with a hard, abrasion resistance, corrosion resistance and high transmittance characteristics, its wide application has a long history. The manufacturing technology of the use of glass a thousand li a day, increasing by the clock, glass, doors and windows, lamps, such as high-tech electronic components and space technology, are indispensable glass. Our daily contact with most of the "flat glass is" thick to thin for doors and windows, clocks and the use of medical tests, the manufacturing method is that the furnace in the glass slurry level or traction method (also called float) and vertical traction method. After the dissolution of soluble traction after furnace also has the cooling system, cooling after the completion into a "flat glass, flat glass thickness mainly depends on the speed of traction, traction faster, can be manufactured and thinner. Although the ordinary flat glass from the front appears bright transparent, but from the side near the edge is slightly blue, because the amount of glass color depends on the main raw material in the manufacture of glass - quartz sand and iron content of purity. Generally, the thin glass used in the watch industry is superior in quality but expensive in value. The main difference is that the raw material used in the quartz sand is superior and the iron content is very low (usually under 3/10000)
Q:Ceramic pots are sprayed glaze, or the whole porcelain crystallization good?
Spray glaze workshop generally volatile material is relatively small, so, as long as a good protection, do not spray out of the glaze and lungs can be. Ceramic factory occupational disease is mainly pneumoconiosis, but now most of the ceramic dust prevention in this area is much better than before.
Q:What are the chemicals in glass?
Common raw materials are quartz sand, feldspar, calcite, calcium carbonate, three, two aluminum oxide, sodium carbonate, borax and so on.
