Q: What is the strength of high strength refractory material?: Refers to constrcuting through ramming, and a refractory materials that is hardened in temperature higher than normal. mixed through a certain grade of refractory aggregate, powder, binder, additives, water or other liquids. Can be classified into high alumina and fireclay, magnesite, dolomite, zirconium and silicon carbide by the standard of texture.

Q: How long does it take for refractory cement to solidify?: 1. First you should be aware of the concepts of condensation and condesation time. Refractory cement belongs unshaped refractories, which when added water or liquid binding agent to mix, the agitation material will gradually lose thixotropy or plasticity and become in a state of solidification, thus is solidified. The time needed to finish the process is called solidification time. The whole process is divided into initial and final set. When beginning to lose plasticity called the initial setting, when called plasticity completely lost the final setting. 2. For refractory cement, the solidification time depends on the matching of the material and the parts and using methods. Under normal circumstances, in order to meet the requirements of time of construction, the initial set time should be no shorter than 40min, and the final set time should be no longer than 8H 3. There are also some exceptions. When refractory cement is used for spraying and injection operation together with other refractory castable, the set time is required as short as possible, sometimes flash set is required to prevent the occurrence of peeling or collapse of the spraying layer.

Q: Where is the distributing center of refractory materials in China?: The infrastructure is perfect, service and refractory chemical industry professional market ancillary services, information, transportation, food, housing, and other one-stop perfection. The business service center, Yongan business city, Fukang company, Xu Bai Anlong logistics center and the market has been basically formed, the market in more than 200 dressing rooms at the end of September put into use, logistics center, warehouse industry nearly twenty thousand square meters can use for customers. The Fasthotel, the dormitory and the information center will be ready for delivery, and large transport teams will be built to provide accommodation, freight and other convenient services for the owners.

Q: How long is the duration of fire resistance that fireproof window of level B can endure?: Level B refers to the fire resistance rating and different hours in fireproofing of the fireproof window. Fireproof window of level A can endure fire for 1.5 hours while level B, 1.2 hours

Q: Which brand of AAA refractory is good?: Foshan Nanhai Yanbu Shuying fire-resistant insulation material is very good, and it is a professional company of the production and sale of refractories. Our company specializes in the production of refractory bricks, refractory bricks, refractory castable, refractory aggregate, refractory materials, bauxite, alumina bricks and to undertake the production of various common refractory bricks and non-sizing bricks. The Zhengzhou Fire High Temperature Materials Co., Ltd. is also a good company. It is a collection of R & D and production company. The company mainly produces refractories, refractory bricks, refractory castable, refractory aggregate, refractory materials, special refractory bricks.

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. It can be sawed, nailed, and glued. 3, the use of glass magnesium plate: Glass magnesium board is a basic intermediate materials Main occasions for applications: HPL Series: Top of the tunnel ceiling. Decorative plate series: Decoration in hotels, office buildings, residential buildings Board series: Ceiling, partitions, fire proof doors and other products. Sound-absorbing panels: Subway, railway stations, theaters, factories and other public buildings.

Q: What is neutral refractory? Can refractory suppliers tell the main components of it?: // Baike? Url x3d CQ3i6_yUCWUMgk3aaRGGLURNtvKPl5IdZpj35Yvommk7Nyif0IJD-SkdIW29GCHwLpb9cT9Ii25GLcEJg-ZHcq "target x3d" _blank "x26gt; http://baike.baidu.baidu.

Q: What are the specifications of fireclay bricks?: 1. The various classification criteria of clay bricks. First, according to the physical and chemical indicators, they can be divided into these types: (NZ) -42, (NZ) -40, (NZ) -38. Second, the classification of specifications of clay bricks is in line with the stipulations in "general shape and size of refractory bricks". Finally, according to the stipulations of relevant state departments, the clay bricks can be divided into standard bricks, ordinary bricks, special-shaped bricks, special bricks. Second, level of refractory temperature of refractory bricks The refractoriness of refractory bricks is divided into four levels according to changes of alumina content. We know that the components in clay bricks include Al2O3. Alkali metals are also included. The refractoriness of AAA-level clay bricks in Ruitai Refractory Material Factory is 1750 ℃; A-level bricks is 1730 ℃; B-level bricks is 1670 ℃; and C-level bricks is 1580 ℃. The softening temperature under a fixed load of Clay bricks is about 1350 ℃. Clay bricks, also known as sintered bricks, are small size artificial bricks for modern architecture. Clay bricks have good properties and high thermal stability, in which Fe2O3 content is less than 2.0 to 2.5%. Overall dimensions: 230 * 115 * 65mm

Q: Does the aluminum silicate thermal insulation material fireproof?: How does its fireproof?performance? this is the material that the decoration master worker recommands to me, how do you think of it?
