Q:Glass fiber raw material price increases, the impact on the glass fiber industry?

A group of small and medium enterprises will face great pressure, especially the focus will be on reducing costs and expanding production, often ignoring product quality and marketing strategy, in the market competition in a disadvantageous position.

Q:Ask the glass making processWhat kind of material is the glass made of? What material is good?

The glass production process mainly includes: raw material pre processing. The massive raw material crushing, wet material drying, iron containing raw materials for iron removal treatment, in order to ensure the quality of glass batch preparation. 2. The melting of glass batch. High temperature heating in the furnace or crucible kiln, to form a uniform, no bubble, and meet the requirements of molding liquid glass. The forming of liquid glass products. Processed into the required shape, such as tablet, a variety of utensils. The heat treatment by annealing and quenching process, eliminate the internal stress generated or glass phase separation or crystallization, and the change of glass structure.

Q:Is flat glass the main material or structural component in raw materials?

In addition, the glass door glass cabinet for calculation of the force, to ensure safe and effective, can also be seen as a structural member, but it is not in the strict sense of flat glass, because has been processed, should be called glass semi-finished products or components, according to whether the main responsible carrying tasks, not to calculate the bearing capacity and determine its structure or not.

Q:Tile selection, paving process

The base should be clean, irregularities to chisel and repair, base should be clean, not a mortar, especially lime mortar, oil, and water wet ground.When laying stone or ceramic tile, standard blocks shall be placed. Standard blocks shall be placed at the intersection of cross lines and diagonally installed.Paving operation to each line in line, the stone must be soaking wet, dry wipe back.

Q:How is glass made? What material is it made of?.

Bullet proof glass is made of glued laminated material, which is glued together with many pieces of glass or high strength organic board. Generally has the following three layers of structure:Bearing layer: firstly, the layer is broken by impact, and the glass with large thickness and high strength is used. It can destroy warhead or change warhead shape, and make it lose the ability to move forward.Transition layer: the general use of organic adhesive material, strong adhesion, light fastness, can absorb part of impact energy, change the direction of the bullet forward. A very strong and transparent chemical film is sandwiched between laminated glass. This can not only effectively prevent bullet shooting, but also has the properties of surge resistance, explosion resistance, shock resistance and no cracks after impact.Safety protection layer: this layer is made of high strength glass or high strength transparent organic material. It has better elasticity and toughness, can absorb most impact energy, and ensure that the bullet can not penetrate the layer

Q:Aluminum alloy window material is good, how to assemble?

Glass: used for aluminum alloy doors and windows, ordinary flat glass, it is best to float process produced by flat glass. There are toughened glass, pointed glass, heat reflective glass, etc..Auxiliary material: filling material, glass cushion block, sealing material.Filling material: it is used as the backing material for filling seam. It belongs to R polymer foam, and its shape is generally round, semicircle, oval and triangle. Specifications are lOmm, 30mm and 50mm three kinds of polyethylene foam. The elongation is 50% and tensile strength is between 0.359 and 0.517MPa.

Q:How is glass made? I heard that sand is used, but what is the concrete principle?

Technological process:1, raw materials broken: the above raw materials broken into powder;2, weighing: according to the list of ingredients, called a certain amount of powder;3, will be called: the mixed powder mixing, stirring into a batch (colored glass and colorant);4, melting: the mixture into the glass furnace, melting at 1700 degrees into glass;5, forming: the glass liquid into a tin bath (float), pull machine (lattice method), rolling machine (rolling method, adding metal wire is wire glass), forming the flat glass;6, annealing: the molding of glass products into the annealing furnace annealing, balance the stress, to prevent self cracking.

Q:Is glass steel pipe used for re examination?

The main construction phase: a layer structure (scheme, technical disclosure basis has been included, steel raw materials, testing report report, flash butt welding, electroslag welding sampling, sample, steel concealed, reinforcing steel bar, batch inspection, template technology review).

Q:What kind of material is glass made of?

1. isotropic particles of glass are arranged irregularly in general, but are statistically uniform, so that their physical and chemical properties are the same in any direction. The crystal is anisotropic. Examples: resistivity, thermal conductivity, transmissivity, refractive index, etc..2. there is no fixed melting point. Glass changes from solid to liquid and varies gradually over a range of temperatures. The crystal is determined by melting point, for example, (water ice crystals) in C melt 0 Eve joy. This property of glass makes it possible to be shaped by blowing, pulling, pressing, and other methods.3. tunability of composition and properties. The properties of the glass may vary continuously and gradually within a certain range with their properties. The crystal has a fixed component and a definite performance. In this way, we can adjust the composition of the glass, so that its performance meets the requirements of the use.

Q:Civil construction projects, exterior wall glass curtain wall raw materials, or construction process, or the end of the construction, what tests should be done?

Do material testing (including stone moisture content, strength, steel and aluminum, chemical anchor pullout test, compatibility test of sealant, epoxy resin structural adhesive test), four test (water tightness, air tightness, wind pressure, plane deformation etc.)
