Q:What kind of material is used on the road zebra crossing

In tile production, feldspar mainly acts as a "flux". During the heat treatment, the flux begins to melt at a lower temperature, so it increases the strength of the ceramic body as a bonding element. In the production of ceramic industry, but also the use of a large number of other natural minerals and some synthetic chemical raw materials, of which the more important raw materials and their molecular formula as follows: Raw material table Chemical composition of natural minerals Synthetic chemical composition of chemical composition of clay (three Alumina - two silicon dioxide - two water molecules) alumina (alumina) feldspar (potassium oxide or sodium oxide - aluminum oxide - six silica molecules) (Calcium Oxide) Tin Oxide (Calcium Oxide) Tin Oxide (Calcium Oxide) Tin Oxide (Tin Oxide) Magnesite (Magnesium Carbonate) Barium Titanate (Barium Oxide - Titanium Oxide) Talc (Three Oxidation) Magnesium oxide - four silica - water molecules) lead zirconate (lead oxide - zirconia) nepheline syenite (potassium oxide - three oxide nano - four aluminum oxide - nine silica + feldspar ) Iron oxide (ferric oxide) zircon (zirconia-silica) silicon carbide (silicon carbide) anhydrous borax (sodium oxide - boron oxide - ten water molecules) barium carbide (barium carbide) pyrophyllite (Aluminum oxide - four silica - water molecules) boron nitride (boron nitride) spodumene (lithium trioxide - aluminum oxide - six dioxins Silicon oxide) cobalt oxide (cobalt oxide) beryl (beryllium oxide - aluminum oxide - six silica)

Q:For the hotel, hospitals, office buildings, residential and other buildings, for the wire tube material selection, there is no relevant specification is clearly what material? Whether it is PVC pipe or galvanized pipe, or other materials, in the unknown. Detailed, I will give more points more

Hello there. The problem you are talking about is a matter of fire. Generally for the use of public places in the wire pipe, the fire department is provided, need to achieve a certain fire rating. If you meet the fire rating, use galvanized pipe or use PVC pipe can be. In other words, if you are using a PVC pipe, you need to send this pipe to the fire department. If it is allowed to use, but can not be used - this is the quality of the material problems. In addition, if the building property designated construction unit must use galvanized pipe, also need to use galvanized pipe construction. Of course, the use of galvanized pipe to do wire tube, in the fire more easily through the acceptance. Specific details, you can directly query the relevant fire regulations.
