Q:Can ordinary white glass (Bai Jiuping) replace quartz glass?: 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, mainly because the material used in quartz sand is superior and the iron content is very low (usually under 3/10000)

Q:Does anyone know iPhone's toughened glass production process? Thank you: Chemical strengthening of good products, or the need for ultrasonic cleaning machine cleaning (quality inspection);(if you need a AR antireflection coating processing, processing, without careful confirmation, currently do not know the first AR coated glass is strong, whether it is feasible, if not feasible, AR coating will in strong, should be on the back of the glass doesn't need AR coating; positive surface is there, I'm not sure. There is supposed to be, the film will affect the resistant to scratching, maybe not, I'm not sure)

Q:Is the production of glass materials as thin as possible? Why?: Superfine powder in water, stirring, mixing will form a group, how big a mass is equivalent to how much a grain of sand, that is not melting, and eventually in the glass liquid to leave stones, become impurities.

Q:Why a broken glass film: A ton of glass raw materials, at least 3-4 of nickel sulfide crystals, the number of tons of glass made of pieces of a square size glass, which will have 3-4 to explode, which is self depicting the image of.

Q:What kind of glass material is used in the aquarium?: Toughened glassToughened glass is a kind of high strength safety glass which is heated by glass to softening point and then cooled rapidly. Under the same thickness, the flexural strength of tempered glass is 4-5 times higher than that of ordinary glass, and the impact strength is 5 times higher than that of ordinary glass. Toughened glass has a strong thermal stability and can withstand severe temperature changes without damaging it. The most important feature of tempered glass is safety. This kind of glass is broken into similar honeycomb particles, so it can avoid the harm to human body. Note: after tempering, the glass can not be cut, drilled, slotted and so on. Because glass is broken into honeycomb like particles that are completely irreparable, it is not recommended for use on aquariums!

Q:What material does PCB have?: The surface of the substrate is covered with a layer of high conductivity, good welding of pure copper foil, commonly used thickness of 35 ~ 50 / Ma; copper foil covered in copper clad laminate substrate side called single copper, copper clad laminate substrate on both sides covered with copper foil called double-sided copper clad laminate; copper foil can securely covered on the substrate. The adhesive to complete. Commonly used CCL thickness of 1.0mm, 1.5mm and 2.0mm three.

Q:What's the connection between tempered glass and float glass?: Tempered glass will float glass cutting, grinding, drilling, backward tempering furnace heating to glass softening point, rapid and uniform cooling, change the compressive stress of glass, a mechanical properties of good glass products

Q:There are several appearances of the quality defects of ordinary flat glass: If molten glass contains gas, it forms bubbles when it is formed. Bubbles mainly affect the transmittance of glass, reduce the mechanical properties of glass, but also affect people's vision, resulting in deformation of the biological image, the main reason is that the purity of raw materials is not enough.

Q:The main chemical constituents of ordinary glass: In the process of making glass, if you add some metal oxides, can also be made of colored glass. For example, adding Co2O3 (cobalt oxide) after the glass is blue, after joining the Cu2O glass is red. We see the ordinary glass, generally pale green, this is because the raw material is mixed with two valent iron for the sake of.There are many kinds of glass. Besides the ordinary glass introduced above, there are some other kinds of glass, such as quartz glass, optical glass, and so on

Q:How do you make the glass, please? What is the raw material?: When you look for information, the proportion of raw materials is very important.
