Q:What are the chemicals in glass?

(some of these ingredients are repeated, and the content of the active ingredients should be carefully calculated when firing the glass) In addition, there are some trace elements, such as metal oxides, used for colored glass, shielding electromagnetic, optical glass and so on. Some other types of special glass materials account for a large proportion of raw materials, and may even contain quartz sand.

Q:Chemical materials and additives needed for the production of glass

Production process of 1.3.1 glass1. Raw material pretreatment. The bulk raw materials (quartz sand, soda ash, limestone, feldspar, etc.) grinding, so that dry wet raw materialsDry, iron containing raw materials for iron removal, in order to ensure the quality of glass.2, batch preparation. According to the product, the composition of the mixture is slightly different. For example, ordinary float glass batch (calculated in accordance with 1 weight boxes of 50 kilograms), need to consume 33.55 kg of quartz sand, limestone, dolomite, 2.96 kg 8.57 kg 11.39 kg of soda, Glauber's salt 0.55 kg, 3.45 kg, 0.03 kg of feldspar powder etc..3, melting. The glass mixture is heated in a bath or crucible furnace at a high temperature (1550-1600 degrees) to form a liquid glass that is uniform, free of bubbles and conforms to the molding requirements.

Q:Tempered and reinforced glass

Tempered glass is a safety glass. It is very small and won't cause serious damage when broken. Toughened glass does not belong to safety glass. Large pieces of debris can cause serious damage.

Q:Not man-made destruction, why toughened glass suddenly broken?

This is because of containing nickel sulfide crystal glass raw material, manufacturing technology in the world is any existing can not be completely avoided, only reduce the exploding probability through control of the purity of raw materials and processing technology to a.It blew the concept of rate, the national standard of our country only glass project on the wall, I do not know whether the other foreign industry to use the toughened glass also has detailed provisions.

Q:What kind of glass is alkali free high borosilicate?

Alkali free borosilicate glass has the characteristics of high surface smoothness, low coefficient of expansion, high temperature resistance, no alkali precipitation and good insulation. Without potassium and nano plasma, it is an important glass raw material for the electronics and Optoelectronics industries. In addition, they do not contain arsenic, antimony, barium, and halides.

Q:Who has information about power plants chimneys, water glass, acid resistant concrete?

Water glass acid resistant concrete raw material: water glass, acid resistant concrete raw materials, including cementation material, curing agent, acid resistant aggregate and admixture. The composition of water glass and acid resistant soil is different, and the prepared concrete will have different properties and range of application. 1) cement material - water glass: building engineering usually use sodium silicate glass (including Na20). Divided into powder water glass and liquid water glass according to their different states. Liquid water glass is a fine quartz sand, S102 (or quartzite) mixed with sodium carbonate in a certain proportion, placed in a furnace of 1350 - 1400 DEG C, and cooled by melting reaction to be a semi-finished product of solid water glass. The solid water glass is put into the autoclave, and the water vapor is dissolved into water so that a practical liquid water glass can be obtained. The liquid water glass can be obtained by two times of spray drying, which is usually called sodium silicate powder. The modulus and specific density of water glass have great influence on the properties of concrete. In order to guarantee the technical performance of acid proof concrete, the water glass of suitable modulus and specific density must be chosen. According to the experience of acid proof construction, water glass modulus 2 is recommended. From 6 to 3.O, the corresponding specific density is from 1.38 to 1.40. Water glass appearance is colorless, slightly blue transparent or translucent viscous liquid.

Q:What are the materials for car windshields? Is there anything different than ordinary glass?

Area of toughened glass is a new type of toughened glass, it through special treatment, can impact rupture, crack the glass can still maintain a certain clarity, ensure the driver's field of vision is not affected, has been widely used in the front windshield of the car, but with the demand for vehicle safety and the car environment continues to improve, with the safety performance of laminated glass with good heat insulation and sound insulation performance has gradually become the mainstream of the front windshield.

Q:What is the raw material of glass made of?

The glass raw materials used for the natural ore, so the manufacture of glass, first of all to all kinds of ore crushing, processing into powder, then according to the glass component, made with the material into the glass melting furnace for melting glass forming liquid. Qualified glass flows through the feed tank and flows out of the feed port to form the stock. The temperature of the stock is 1150~1170 degrees centigrade and the alkali free glass is 1200~1220 degrees centigrade. The material shares every minute near '200 times cut into ball billet. The billet passes through the chute, the ball distributor and the ball plate, and then rolls into different funnels respectively, then falls into a groove formed by three rollers with the same rotating direction. When the ball is rotated on the roller and its surface tension, the ball glass is formed gradually. Its diameter is determined by the thickness, velocity, and shear velocity of the glass stream.

Q:What is the density of glass flake cement?

The bulk density of glass flake increases with the decrease of particle size.Glass flake resin (Glass flake mastic) is made of resin as binder, glass flake and powder, etc. it can be scraped and mixed with construction materials.

Q:The shell of glass steel electric cars will not be on the poor out of the glass Sizha?

There are 2 kinds of process for making automobile shell with glass fiber reinforced plastic, 1. hand paste forming process and 2. pressing processThe choice of raw materials is reasonable, according to the operating procedures, the product is not defective, will not appear exposed fiber, it will not cause skin itchingA small number of unscrupulous manufacturers, technical level is low, Jerry built products must be betterYou can spray a layer of resin or a layer of dry adhesive tape on the exposed surface of the fiber when you encounter inferior products
