Ordinary glass tableware is not completely reliable. In a specific environment that is immersed in water for a long time, it will produce a "mold" phenomenon. This is because the glass is eroded by water for a long time, and the sodium silicate in the glass reacts with carbon dioxide in the air to form white carbonic acid crystals, which are harmful to human health. The way to get rid of these carbonic acid crystals is to wash them with alkaline detergents. Although ordinary glass may also contain trace amounts of lead, it is not harmful to health under normal use. If you are worried, soak ordinary glass tableware in vinegar water before use to make the lead precipitate out. For acidic beverages or food, use ordinary glassware and try to avoid lead-containing glassware.

What is the production process principle of colored glass?

There are various production processes for color flat glass. For body-colored flat glass, float method and flat drawing process and casting calendering process are mainly used at present. Float and levelling Float and flat glass are the main production processes of flat glass, and they are also the main production methods of color flat glass. We mix the colorant and glass raw materials evenly, and then send them to the glass tank kiln through a feeder for melting, clarification, molding, etc. The process obtains colored flat glass. Since colored glass is different from ordinary flat glass, the melting system and annealing process should be different from ordinary flat glass. In addition, some transition glass will be produced during the production and conversion of colored glass. Color change in glass production In the flat glass production line, the conversion production of colored glass mainly adopts the "production process refueling method". The method is: according to the color uniformity and quality requirements of good products, without affecting production, put the newly composed batch into the original glass liquid, so as to gradually replace and change the color of the glass in the shortest possible time. Convert to another color. Generally, it takes 6-14 days for all the molten glass in the whole kiln to be converted into the newly composed molten glass. The time is related to the time that the molten glass stays in the kiln, that is, the ratio of the total capacity of the molten glass in the kiln to the production certificate; it is also related to the amount of colorant added. Practice has proved that the speed of glass coloring conversion is not only related to the unique glass flow of each kiln, but also depends on the coefficient of blending excess colorant, which is generally 2-3 times the amount of standard colorant. Since changing the addition amount of the colorant has little effect on the composition of the base glass, the blending excess coefficient of the colorant can be adjusted within a wide range. The greater the amount of colorant added, the faster the colorant content in the finished glass rises, and the faster the glass is colored. The colorant content Cx in the glass is expressed by the following formula. Cx=T×Co/R(B)/Tr In the formula, T is the coloring time, hours; C. is the design content of colorant in the finished glass; R(B) is the coefficient related to the blending excess coefficient B; Tr is the ratio of the production capacity of the kiln to the off-duty output. According to production experience, the relationship between B and R(B) is as follows. If B is too large, it will cause difficulty in melting at the front end of the glass melting furnace, so B is usually not greater than 5: B=l,R(B)=2; B=2,R(B)=0.1; B=3,R(B)=0.4; B=4, R(B)=0.3. Among them, T, is a ratio, which is equivalent to the average time that the molten glass stays in the kiln. For a 400t/d float glass production line, if the total volume of molten glass in the kiln is 2400t, Tr=2400/400=6 days. In addition, if starting coloring with the blending excess coefficient B, the entire glass kiln already contains the same glass colorant components uniformly, and the colorant-related components in the finished glass have reached Cy, then Cx=T×Co/R( The formula B)/Tr+Cy is the estimation formula for the coloring rate of float glass.

What is tempered glass?

Glass can be seen everywhere in our life, it can be said to be all over the world. We all know that glass is a kind of thing that is easily broken. How much do you know about tempered glass? What is the difference between the two types of glass? Tempered glass definition: Tempered glass, also known as tempered glass, is actually a kind of prestressed glass. It is made by heating ordinary glass electrically in a tempering furnace and rapidly cooling it with a fan. It is commonly used as flat tempered glass. Tempered glass application areas: Tempered glass is widely used in furniture, electronic appliances, construction, decoration, bathrooms, cars, escalators, and other places that require special safety and have drastic changes in temperature, and can be used as a raw material for insulating glass and laminated glass. piece. Brief Description of Tempered Glass: Tempered glass is a physical or chemical method to form a compressive stress layer on the surface of the glass. The glass itself has a high compressive strength and will not cause damage. When the glass is subjected to external force, this pressure layer can offset some tensile stress and avoid glass breakage. Although the tempered glass is in a state of large tensile stress, the interior of the glass has no defects and will not cause damage. , and then arrive at the intention of increasing the strength of the glass. Tempered glass classification: According to the original glass used, it can be made into general tempered glass, endothermic tempered glass, color tempered glass, tempered insulating glass, etc. Tempered glass market prospects: Most of the tempered glass on the market is used in the decoration industry, and its products are mainly bonded to the glass surface through a reinforced film, so that it can strengthen the explosion-proof effect. If the glass is damaged due to external force, the glass fragments will be tightly adhered to the high-strength and high-strength polymer film, and will not fall off, and the safety function is high. There are countless types of reinforced film. Compared with the typical colored reinforced film, commonly known as "photo film", this product uses ink modification skills, so that the color painting is reflected on the film, and then reaches the role of stained glass. Eco-friendly features are low. There are also color films made of printing composite technology. There are many such products on the market, and the types of these products vary from manufacturer to manufacturer. The typical "Diwei film", "Meidi color film", "Dia film" etc., its product characteristics are better than "photo film", the substrate is mostly made of environmentally friendly PET, and the environmental protection and safety functions are ideal. Currently, this product is mostly used in the production of tempered glass.

5 methods of how to detect high temperature tempered glass

High temperature resistant tempered glass is a common auxiliary tempered glass product for industrial boilers and industrial furnaces. There are five main inspection methods: 1. Scale inspection: use a ruler or tape measure with a minimum scale of 1mm to measure the diameter of the glass, Length, width and thickness. When it comes to high precision, it can be measured with a micrometer or an instrument of equal precision, with millimeters (mm) as the unit and accurate to two decimal places. 2. Anti-shock function inspection: including wind pressure resistance function inspection and anti-heavy object falling ball function inspection. 3. Bending inspection: put the high temperature resistant tempered glass upright, and place the ruler horizontally against the surface of the glass for measurement. The bow is expressed as a percentage of the ratio of the height of the arc to the length of the chord. Waveform, expressed as a percentage of the ratio of the trough-to-peak height to the peak-to-peak (or trough-to-trough interval). 4. Fragment condition inspection: place the high temperature resistant tempered glass sample on another sample of the same shape and size, bond the two samples with photosensitive paper, and use scotch tape to stick around the periphery. On the longest side and base line of the sample at a distance of about 20mm around the periphery, impact with a small hammer or punch with a tip curvature radius of 0.2mm ± 0.05mm to break the sample. 5. Appearance inspection: take the product as the real object, and inspect it with the naked eye under better natural light or scattered light conditions. Today's tempered glass not only integrates into our life, but also adds a color to our home. The emergence of tempered glass has deeply driven the development of the glass industry. After many of our homes have such a home, we can be safer and more assured.
