Gypsum plaster board is characterized by light weight, sound insulation, heat insulation, strong processing performance and simple construction method. 2, Gypsum block Gypsum block is a kind of lightweight building gypsum product which is mainly made of building gypsum, and by adding water, stirring, casting and drying. During the process, , the fiber reinforced materials or light aggregates are allowed in, and the foaming agent can also be added. It has many advantages, such as sound insulation and fire prevention, convenient construction and so on. It is a kind of new and healthy wall material which produces low carbon, enhances environmental protection, and caters to the the times. 3, Fly ash brick is a new type of wall material, and bulk density is one of the main technical indexes. The weight of bulk density can be controlled according to the need of construction and adjustment of technical formula. The dry bulk density of the fly ash brick is about 1540 to 1640 kg / m 3, slightly lighter than the clay brick (1601800 kg /m 3). The flexural and compressive strength of fly ash brick is mainly determined by the production process, the formula and the hydrothermal synthesis reaction mode as well as the need of construction. According to the standards of architectural material industry (JC239 - 2001) released by People's Republic of China, the average value of the flexural strength is 2.5 ~ 6.2Mpa, compressive strength is between 10 ~ 30Mpa. I hope this will be helpful to you
Q:What is the role of adding chromium oxide green in unshaped refractory materials
Generally, less is added in corundum or corundum spinel refractory material, but it can significantly improve the material performance such as high temperature strength, erosion resistance, thermal and shock stability, etc.
Q:What 's the highest temperature can magnesium plate glass resist ?
Glass magnesium plate (commonly known as magnesium oxide or glass magnesium plate) is a magnesium jointing material with stable performance made by adding modifier and processing ternary system composed of magnesium oxide, magnesium chloride. It is a new non-combustible decorative materials comprounded by moderately alkaline fiberglass net as enhanced material and lightweight material as filler. 1, Applications Wall panels, ceiling panels, fire-resistance boards, water-proof boards, boxes, etc.. It can replace wooden plywood panel and be made into dado, door panels, furniture, etc., or into distemper paint water paint to one's need, and can akso be processed into various types of plate surface. It is also applicable to projects undertaken in damp environment such as basement, civil air defense, mines. It can be comprounded with a variety of thermal insulation materials into compround thermal insulation materials 2, Product features: Magnesium plate glass is high temperature resistant, sound absorbing, and capable of preventing water, pests, dampness, corrosion, poison, pollution. Paint can directly be applied to the surface of the plate. Air nails are usable for the plate, to which ceramic tile can also be applied with good pigmentation High strength, flexibility when bending, convenient for decoration.

Q:What are the differences between intensive refractory busway and other busways?
Compact busway is named according to its structure, and fire-resistant busway is named after its uses. Compact busway especially refers to busway which is closely laminated between phases and between phase and shell, and use thin insulating material to achieve the insulation result. suitable for power supply system of alternating current three-phase four-wire, three-phase five-wire system, frequency of 50 ~ 60Hz, rated voltage up to 690V, rated operational current of 250 ~ 5000A, as auxiliary equipment for mining, enterprises and high-rise buildings, and especially suitable for the transformation of workshop and old enterprises. Fire-resistant busway is composed of shell coated with fire retardant paint, bus line wrapped with fire-resistant mica tape and bracket made by refractory insulating material. Bracket has a plurality of grooves where inbedding the bus line and fixed it. There is a busway connecting box at one end of the busway and there is a bus line splitter box in the busway. Fire-resistant busway has excellent insulation properties, which can not only be used continuously in a normal environment, but also can be used in the fire environment continuously for more than one hour, suitable for high-rise buildings and important facilities, replacing the fire-resistant cables to transmit and distribute power .
Q:Which industry does refractory belong to?
It belongs to decoration industry.
Q:Graphite and other carbon materials may be oxidized to CO or CO2 at high temperatures. But why can they be refractories?
There is no contradiction for this. Any substance can be combustible, but different materials have different ignition points.There are many types of graphite. Pyrolytic graphite has a much lower ignition point. Therefore, as long as it reaches at a certain temperature, it can convert into graphite. Mostly, in practical applications (such as brake pads will add a certain amount of graphite), graphite is required to have refractoriness of below 1000 ℃. Graphite can serves as both the combustible and refractory material. So, it can be used as a fire-resistant and high-temperature-resisrant material because graphite (lamellar graphite) has a ignition point of at least 3000 degrees in an oxygen free condition. The above information is for reference only and is offered by Xin Ruida Graphite Company.
Q:What are the requirements when producing fireproof materials by kaolin?
Kaolin refractories in fact play a role in two aspects, one is to improve the refractoriness, the second is to improve plasticity of the the refractory . Aluminum content the higher the better, of course, but kaolin is not the only material to improve the content of aluminum, using materials that contain higher content of aluminum such as the bauxite chamotte. So the content of kaolin aluminum does not have to be too high. over 38% is fine. viscosity is important and strong viscidityis better without having to add bentonite. Refractoriness above 1400 degrees is enough.
