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:What kind of glass is alkali free high borosilicate?

At present, abroad can produce high quality non alkali borosilicate glass company, Corelle, the German Schott companies, domestic Changsha have a precision glass raw material sales, precision glass processing company, alkali borosilicate glass, Schott two sales of Corelle company.

Q:Is toughened glass dish loaded with food harmful to human body?

Taking into account the raw materials for the production of glass, as long as the regular manufacturers of products, do not worry about glass tableware precipitation problem is not to precipitate harmful products, but as the glass products, even tempered glass, the first priority is the safety problem, because even tempered glass, also has a certain rate of suicide therefore, strongly recommended the toughened glass into the use of microwave heating.

Q:What are the raw materials for producing edible glass bottles (such as pickles bottles, fermented beancurd bottles, etc.), and glass is the kind of glass material?

The production of glass bottles industry, its raw materials are stone powder, quartz sand, soda ash, waste glass and coalA variety of materials used in the preparation of glass batch, collectively referred to as glass raw materials. In general by the 7-12 component, the main material is 4-6, such as quartz sand, limestone, feldspar, sodium carbonate, boric acid, lead compounds, barium compounds, according to the introduction of oxides in the glass structure effect, can be divided into glass forming oxide materials, intermediate oxide materials, network oxides materials, according to the the properties of oxide, can be divided into raw material, acid alkali metal oxide oxide materials. The glass batch is obtained some necessary properties and accelerate the melting process of raw materials, although less, but it is very important that these materials as clarifying agent, fluxing agent, coloring agent, bleaching agent, emulsifying agent, oxidizing agent and reducing agent etc..The same raw materials, different formulations, the same raw materials, different habitats and different indicators, will affect product quality and production costs. In the case of a small gap in raw material costs, the glass bottles produced are very different from each other in the comparison of small samples, and the difference can only be seen in batch production.

Q:What's the difference between crystal and ordinary glass?

To strike lightly or with fingers. Crystal glass can produce metal crisp sound, and waves a beautiful lingering in the air. We will see at the reception banquet, high-end glasses scenes in the movie, a kind of glass between the collision sound is. And high school, low grade crystal glass sound is also different. Like some low-end crystal glass or ordinary glass voice is relatively boring.

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:How to distinguish between good and bad glass fiber reinforced plastic?

Glass fiber reinforced plastic used for raw materials, resin, glass fiber reinforced plastic fiber silk, filler, calcium powder to 1:1:1 ratio configuration, high-quality glass fiber reinforced plastic choose high-quality resin: unsaturated ortho benzene resin 196, colorless transparent. Low viscosity, low heat release, low shrinkage, high speed cure, high speed compatibility and gloss.

Q:Glass raw materials processing equipment, glass raw materials crushing equipment prices generally sell how much?

Glass raw material processing technology and equipment, advanced at present, glass raw material (quartz sandstone, feldspar, silica) processing generally adopts the following process: A, wet rodmill; B, by the back breaking or jaw crusher and roll composed of multi-stage crushing and screening line.

Q:What is the raw material of glass?

We know that solid materials can be divided into two categories: organic materials and inorganic materials. Organic materials are wood, plastic, plexiglass, cotton, wool, nylon and so on. Inorganic materials can be divided into three categories: single crystal, polycrystal and glass according to the structure. A single crystal has regular shapes and strict rules, such as the ruby is an alumina single crystal, the crystal is a silica single crystal, and the diamond is a single crystal of carbon. Polycrystal is a collection of large amounts of small single crystals, and all kinds of ceramics and metals are polycrystalline materials. Glass is a noncrystalline solid obtained by melting, cooling, and curing. Its structure has certain rules (short-range order) in the atomic and molecular range, but there is no rule (long-range disorder) in the macroscopic range.

Q:Why is toughened glass 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.
