The dining table is a place for gathering and eating. It must be in harmony with the gems and phases of Feng Shui. A person can enjoy three meals a day. The feng shui layout of the restaurant is very knowledgeable. In addition to the table layout, the ceiling of the restaurant is often overlooked by people. However, the ceiling of the restaurant has a great influence on the feng shui layout of the entire restaurant. What is the detailed explanation of the restaurant's ceiling feng shui learning? Follow Xiao Bian to learn about the restaurant's integrated ceiling feng shui.
The restaurant integrated Feng Shui learning detailed ceiling
1, color
The color of the ceiling must be light-colored. The color of the ceiling should be shallow, and the color of the floor should be deep, so that it is in line with Feng Shui's sense of “light weight and weight†and there is no top-heavy pressure on the roof to help people’s physical and mental health.
2, height
The feng shui theory is tempting to use the “beam compression roofâ€, but if the ceiling of the false ceiling is pressed too low in order to relocate the roof beam, it is not appropriate in terms of feng shui or design. In this case, the use of four-sided low-middle high ceiling shapes will not only make it more comfortable visually, but also create a “Tianchi†that gathers water in the middle of the ceiling and belongs to Feng Shui.
3, shape
The ceiling of the dining room is forbidden to use the mouth type, and the mouth-shaped ceiling is added to the center to become a prisoner. This is a big culprit in feng shui. Therefore, it is recommended that people avoid ceiling-shaped ceiling when designing the ceiling.
4, decoration
Many people like to decorate the ceiling of a restaurant for decoration. This is understandable, but it is worth noting that fish bones should be avoided. Fish bones represent poverty and hardship, and there is no fish to eat. Therefore, the bone itself That is why, of course, it cannot be used in the restaurant ceiling.
5, lamps
Lamp selection is very important, it is best to use a round chandeliers or ceiling lamps, because the circle has a full meaning of doing things, which is conducive to a complete family harmony, but also in line with Feng Shui in the Kyrgyzstan.

Introduction
The most common inorganic flame retardants are the hydroxides or aluminium and magnesium. Aluminium trihydroxide (ATH) is by far the most widely used Flame Retardant on a tonnage basis. It is inexpensive, but usually requires higher loadings in polymers of up to more than 60%, because the flame retardant mechanism is based on the release of water which cools and dilutes the flame zone. Magnesium hydroxide (MDH) is used in polymers which have higher processing temperatures, because it is stable up to temperatures of around 300 C versus ATH which decomposes around 200 C.
Fine precipitated ATH and MDH (grain size < 2um) are used in melt compounding and extrusion of thermoplastics like cable PVC or polyolefins for cables. For use in cable, ATH and more often MDH are coated with organic materials to improve their compatibility with the polymer. Coarser ground and air separated grades can be used in liquid resin compounding of thermosets for electrical applications, seats, panels and vehicle parts.
A number of other inorganic substances show flame retarding effects and are used in commercial applications. Most of them are used as synergists i.e. they enhance the performance of other flame retardants or they are used for specific effects like the suppression of smoke formation. For example, borates are used as mixtures of boric acids and borax as flame retardants for cellulose (cotton) and of zinc borate for PVC and other plastics like polyolefins, elastomers, polyamides, or epoxy resins. In halogen-containing systems, zinc borate is used in conjunction with antimony oxide, while in halogen-free systems it is normally used in conjunction with aluminium trihydroxide, magnesium hydroxide, or red phosphorus. In some particular applications zinc borate can be used alone. Boron containing compounds act by stepwise release of water and formation of a glassy coating which protects the surface.
Zinc compounds were initially developed as smoke suppressants for PVC (Zinc hydroxystannate). Later it was found that they also act as flame retardants in certain plastics mainly by promoting char formation.
Intumescent Flame Retardant systems expand to produce foams. They are used as coatings not only to protect combustible materials such as wood and plastics, but also steel structures in buildings, because steel loses its strength when exposed to high temperatures in a fire. The intumescent effect is achieved by combining an acid source like ammonium polyphosphate, a source of carbon, compounds which release noncombustible gases for blowing the foam on thermal decomposition and resin binders to stabilise the foam.
Expandable graphite is manufactured from flake graphite by treatment with strong acids like sulphuric or nitric acid. The acid is trapped in the crystal layers of the graphite ("intercalated"). When it is heated, the graphite starts to expand up to several hundred cm3 per gram, forming a protective layer for the polymer. Expandable graphite is used in plastics, rubbers (elastomers), coatings, textiles and especially in polymeric foams. To achieve an optimum flame retarding effect, the use of synergists like ammonium polyphosphate or zinc borate is often necessary. The black colour of graphite limits its applicability in some cases.
Nanocomposites have been gaining increasing attention since the late 1990s as potential new flame retardants. Nanocomposites
are polymer layered silicates based on aluminosilicate clay minerals like montmorillonite, composed of layers with gaps (gallery spaces) in between. These silicates have the ability to incorporate polymers. Research with nanocomposites has focused on plastics like polymethylmethacrylate (PMMA), polypropylene, polystyrene, and polyamides. Nanocomposites particularly prevent dripping and promote char formation. Therefore, they have been used as synergists in some polymer / flame retardant combinations. However, they require special processing and for the time being are not considered to become viable stand-alone flame retardants.
Other inorganic fillers like talcum or chalk (calcium carbonate) are sometimes denoted as flame retardants, but they do not specifically interact with the ignition process. On the contrary, simply by diluting the combustible polymer they reduce its flammability and fire load.
