Q:what are the types of piping insulation material fire rating?
Pipe insulation material Fire rating: heat conductivity coefficient(at room temperature) 0.025 grade non-combustible Class A low temperature bending ≤ 5000 breaking elongation 5,000 specifications 5000 anti-bending strength 5000 compressive strength 5000 special brand of high use temperature -250 ~ 150 ℃ core material, phenolic foam, form, stratiform, shape,flake.
Q:What is the common inorganic fireproof and thermal inuslation matertial?
inorganic materials of insulation materials 1, inorganic thermal insulation materials are mainly concentrated in the materials that have a certain insulation effect and can achieve level A fireproofing, such as aerogel blanket, glass wool, rock wool, expanded perlite and micro-nano thermal baffle. 2, rock wool production is harmful to human body, workers also do not want to occure the situation under the construction. The cycle of rock wool construction plate is long about 2 years from construction to production. The supply of the domestic wool market also cannot meet the requirements for use. 3, expanded perlite has great weight and high water absorption. 4, the insulation performance of micro-nano insulation panels is 3-5 times that of conventional insulation materials, commonly used in high temperature environment, but is more expensive. 5, aerogel blanket is level A1 inorganic fireproofing building materials, thermal conductivity at room temperature is 0.018W / (K · m), and absolutely waterproofing, its insulation performance is 3-8 times of traditional materials, which can replace the unenvironment-friendly froconventional flexible material with poor insulation properties, such as glass fiber products, asbestos insulation felt and silicate products.
Q:What's the A grade fireproofing material?
A grade fireproofing material: 1. fire-proof plate; 2. fireproof wooden door; 3. fireproof wooden window frame; 4. fire resisting shutter; 5. fireproof and mothproof wood; 6. fireproof glove compartment; 8. fire retardant coating; 9. fire-proof sealing material.
Q:How many kinds of A-level fireproof and thermal insulation materials are there?
Please give us some information about the kinds of A-level fireproof and thermal insulation materials in the market.
Q:whether the fire resistant level of aerated concrete building blocks can reach the grade one?
the fire resistant level of aerated concrete building blocks can reach the grade one level. Aerated concrete strength grade shall be divided according to the concrete cubic compressive strength value. Use the symbol C and the cube compressive strength value (in N / mm2 or MPa gauge) to express. According to GB50010-2002 "concrete structure design specifications" provisions, ordinary concrete is divided into fourteen levels, namely: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75, C80 .
Q:What are the main components of refractory cement?
Refractory cement, also known as aluminate cement, can also be gray. Aluminate cement is often yellow or brown. Aluminate cement takes bauxite and limestone as raw materials, alumina content of about 50% as the clinker. And it is a hydraulic cementing material made by grinding. The main mineral of aluminate cement is mono calcium aluminate (CaO · Al2O3, abbreviated CA) and other aluminates, and a small amount of dicalcium silicate (2CaO · SiO2), etc.
Q:The history of refractory material
Q:What are the fire protection standards of insulation materials?
The combustion performance of thermal insulation materials for exterior walls of all civil buildings, within the scope of fire design auditing and fire control acceptance, should be brought into the auditing and acceptance. As for the "Management Regulations on Supervisions of Fire Prevention and Control for Building Projects" (Ministry of Public Order No. 106) , all civil buildings which are out of the scope of Article 13 and 14 are included in the random check. Before the release of new standard, it must be strictly implemented the Article II of the "Fire prevention Interim Provisions on civil external wall insulation system and external wall decorative" ([2009] No. 46), namely, the insulation materials of civil buildings must use materials with A-level combustion performance.
Q:What's the classification of refractory material?
Magnesium aluminum is complex and mainly seeing what classification standard is like according to the appearance shape can be divided into two categories, setting and not setting according to the acid alkali can be divided into acidic, magnesia, high aluminum, ramming expected, spinel, spray coating, plastic, just the quality of the jade, daub material according to the chemical composition is divided into, such as clay, neutral and alkaline according to the operation mode can be divided into different castable, magnesium, calcium, magnesium chrome
Q:How to count the construction costs of refractories?
In winter, the temperature of the the fire-resistant masonry, fire-resistant plastic, sodium silicate, phosphoric acid castable should be maintained above 5 ℃. Usually greenhouses in which heating facilities are installed to maintain the appropriate temperaturere for the construction environment should be erected in refractory masonry. The temperature around the construction site of the industrial furnace and refractory masonry shall not be lower than 5 ℃.
