If you’ve kind enquiries, please don’t hesitate to let us know. ^_^

Q:Who knows what is the requirement for fireproofing of interior decoration materials ?: In addition to the underground building, combustion performance level of interior decoration materials inside windowless room , in addition to a class, should advance 1 level based on the original provisions . Library, archives and rooms storing artifacts, ceilings, walls should use class A decoration materials, and the ground should use decoration materials no lower than class B. When high temperature parts of lighting and lighting lamps and lanterns are close to non - grade A decoration materials should be taken, fire prevention measures such as thermal insulation and heat dissipation must be taken. Combustion performance level of materials used for lighting should be no lower than B. Kitchen ceiling, wall and floor should used class a decoration materials.

Q:What are unshaped fire-resisitance materials?: Refractory castable, refractory plastic material, usually classified according to construction and manufacture method, unfired bricks precast block, refractory pressed into material, refractory cast material, refractory coating, refractory ramming material there are many classification methods

Q:What kind of refractory materials are used in metallurgy industry?: Argon-blowing rod, siliceous dry vibrating materials, desulfurizer, slag-stopping ball, stainless steel thermal insulating agent with high efficiency, dry vibration material, sizing nozzle heat-insulating panel, chrome refractory , refractory carstables for ladles, magnesia carbon refractory, package castable, siliceous drainage agent, tundish block, iron trough, deoxidizer, compound deoxidizer,silicon manganese alloy , stemming, floating plug,slagging agent. The main materials are as follows: recarburizer, covering agent, intermediate frequency furnace burden, mould fluxes, insulation thin slag agent, skimmer repair material, joint sealant.

Q:What are the fire protection standards of insulation materials?: According to the three versions of GB8624 (1997,2006,2011), the fire rating of external walls can be basically divided into: A1-, A2-, B1-, B2-, B3-level. The detailed divisions are determined by many technical indicators. It is a very professional and technical long story. Please contact QINGDAO SHANFANG INSTRUMENT CO., LTD for detail information, they are specialized in manufacturing fire rating testing instruments of external walls.

Q:What are the specific steps of stirring the steel ladle castable?: Steps are as follows. 1 Compulsory mixer is used to stir the castable and bags, rope and other debris can not mix in the castable when stirred. 2, Castable should be unpacked on the scene. Stirred volume depends on the capacity of the mixer. Castable should be accurately measured and put into a blender. 3 The process of first dry mixing and then wet mixing is adopted. After the castable is added to the mixer, it is dryly mixed for 2 minutes, add about 5.2 to 5.5 percent of water and continue to add water while stirring. Water that is 80% of the total should be added, and then decide whether to continue to add or not depending on the consistence (noting that the water must be clean water and sewage can not be used). Then it is wetly mixed for 4 minutes and stirred for not less than 6 minutes at one time, until castable is even. In general, the bottom is slightly dry and the wall of the ladle is slightly dilute (the amount of water is only for reference). 4, The amount of water and mixing time should be controlled strictly when stirred to ensure that the needs of the consistency are met. If castable is too thin, it will seriously affect the quality of the material. The stirred volume, stirring time and water that is added should be consistent and they can not suddenly be thick or suddenly be thin. If the consistency does not meet the requirements, the castable should be put back to the mixer and stirred with appropriate water or dry materials. 5, It should be stirred evenly and casting should finish in 20 minutes, in order to avoid sclerosis, affecting structural strength of ladle lining 6, After each completion of construction, varieties of castable should be changed and the mixer should be cleaned 7, Stirring can stop in halfway. If the mixer breaks down and it can be repaired in a short time, some of the materials have to be removed before the machine is opened. If the machine can be repaired on time, castable refractory should all be removed.

Q:Refractories for iron-making blast furnace?: Cement kilns?

Q:What's the fire endurance of fire windows?: That is fire resistance rating, fire-resistant time in the case of fire! It can be basically classified into the following levels and the fire endurance of the fire window is as follows as well: A class fire window: no less than 1.2h; B class fire window: no less than 0.9h; C class fire window: no less than 0.6h. This is in accordance with the latest specification of gb16809-2008 fire windows.

Q:I am a refractory material manufacturer, sold products, money is always not back, anxious to die, what is the way?: Metallurgical industry downturn. There is fierce competition in the refractory industry.

Q:Which are roofing fireproofing material?: (1) Foamed concrete is a kind of fire-proof thermal inuslation matertial featured by good fire resistance and thermal insulation. Besides, it is also characterized by excellent sound proofing, penetration resistance, easy construction, safety and environmental protection without toxin and pollution. (2) Foam glass is featured by light weight, small heat conductivity coefficient and water absorbption, non-inflammability, fire resistance, high strength, no moulding, corrosion resistance, non-toxin and stable physical and chemical properties and thus widely used petroleum, chemical engineering and underground construction. It is also featured by thermal insualtion, heat/cold preservation and sound absorbption and thus can be used for thermal insulation of external wall and roof of civil builduing. Foam glass is featured by stable chemical property, easy to be processed and not easy to deforme, and durable. (3) With slag, basalt and other natural ore as the main raw material, rock wool, mineral wool and its products are made by high temperature melting into fiber, and then processing with binder. It has low thermal conductivity, fire resistance, easy construction and good effects of energy saving and thus is highly cost-effective. (4) With phenolic foam material as main material, phenolic resin plate is made by foaming thermoset phenolic resin. It is featured by light weight, fire resistance, no burning in the air, no smoking, non-toxin, no dropping and non-embrittlement and thus is an ideal thermal insulation material used in HAVC projects. Due to its high obturator formamen rate, low heat conductivity coefficient, good thermal insulation, water resistance and water vapor permeability, phenolic foam is an ideal thermal insulation material.
