Q:What are the properties of fire-resistant coatings for steel structures?
Thick steel structure fire retardant coating refers to the steel structure fireproof coating with coating thickness greater than 7 mm, less than or equal to 50 mm, granular surface, little density, low thermal conductivity, and refractory limit of 2 h or more. Because of the thick fire retardant coating composition for inorganic materials, so the fire performance is stable, long-term effect is good, but the coating components of larger particles, the coating appearance is not smooth, affect the overall appearance of the building, so most structure for concealed works. In the fire, the material has a granular surface, a smaller density, a low thermal conductivity, or a heat absorbing property in the coating, delaying the temperature rise of the steel and protecting the steel. This kind of fire retardant coating is suitable for inorganic binder (such as water glass, silica sol, aluminum phosphate salt, refractory cement, etc.) together with inorganic light insulation aggregate materials (such as perlite, vermiculite, bouldering, sea and fly ash cenosphere), fire retardant additives, chemicals and materials (enhanced such as rock wool, aluminum silicate fiber, ceramic fiber, glass fiber and filler) mixed together, has the advantages of low cost. Spraying is often used in construction. It is suitable for indoor and outdoor concealed steel structure, high-rise steel structure and multi story steel structure with requirements of fire resistance above 2 h. Such as: high-rise building columns, general industrial and civil buildings in support of multi-storey columns of fire resistance should reach 3 h, the need to use this thick fire-retardant coating protection.
Q:8cm what is the sound volume of the soundproof cotton?
You said if you want to use 8cm cotton insulation wall system to suppress the noise effect, must be added on both sides of the insulation cotton high density (or surface density) of the building materials, such as gypsum board, glass magnesium board, calcium silicate board, fiber cement board and so on. If we want to ensure that the partition wall should not be too thick, and to ensure the sound transmission loss of more than 50dB, it is not up to use the common plate, must use the Chong Ning insulation board and other professional sound insulation board, can achieve the wall thickness in the case of 100~130mm Rw, the weighted sound insulation amount reached more than 50~54dB, and the highest standards of sound insulation value reached the national standard of civil building insulation standards.
Q:The water heater for what the security hole tube
Asbestos exposure to the skin for a long time, harmful to the skin, eating into the body harmful. Pack on the exhaust pipe, do not move it, there is no harm.
Q:How about the appearance of glass wool, mineral wool and asbestos?
A fluffy short staple fiber made from mineral material. Including rock wool and slag cotton. Melting natural rock or metallurgical slag in a cupola or a pool furnace, etc. by blowing or centrifuging.
Q:What kinds of exterior wall thermal insulation materials are there in Northwest China?
Experts from authoritative institutions of Beijing Haina LIAN inorganic fiber spraying technology Co., Ltd. development of ultra-fine inorganic fiber spray identified, it is for the further development of the enterprise is undoubtedly a new impetus. I learned that the evaluation results, both for the enterprise is also happy, for the enterprise how to further enhance their ability of research and development and to further explore this, more hope that the enterprises can take the assessment results in the East, as the struggle to make "Heiner fertility LIAN" on the floor again!
Q:Does water paint spray fire in underground space?
Waterborne paint itself is waterproof, unlike oil paint as security for.
Q:Advantages of exterior wall energy saving and environmental protection heat insulation coating
Although the market is rich in exterior wall insulation products, but inorganic thermal insulation materials in addition to A-class fire retardant performance and good insulation effect, but also has excellent insulation system structure without network. In simple construction, and buildings with life, water resistant anti crack and anti hollowing fields occupy an increasingly important position.
Q:Fireproof rock wool board can be used as firewall?
Rock wool board mainly by hydrophobic rock wool board pendulum method for production of insulation layer material, composite rock wool board is the natural rocks such as gabbro, Xuan Wuyan, dolomite, iron ore, aluminum and vanadium as the main raw materials, inorganic fiber adding binder, hydrophobic agent by high temperature melting, made of fiber the implementation of standards, GB/T25975-2010 is "building exterior insulation rock wool products"; rock cotton in the industrial slag blast furnace slag such as slag, phosphorus slag and fly ash as the main raw material, inorganic fiber after remelting fibrosis made. This paper introduces the main A-fire exterior wall external insulation system on the market (the following text from Chinese architectural design and Research Institute of standards "exterior insulation construction" Standard No. 10J121) the implementation of standards is GB/T11835-2007 "insulation rock wool, slag wool and their products".
Q:What are the differences and prices between rock wool board and mineral wool board?
The habit of speaking, usually will use slag as the main raw materials to produce products known as mineral wool, and the use of natural rocks such as basalt or diabase as the main raw material for the production of a product called rock wool;
Q:What are the types of insulation materials used in pipes and equipment?
Glass wool is a fibrous material made from the melting of glass or crushed glass. It consists of two kinds of short cotton and superfine cotton.Features: glass wool can maintain good insulation performance under high temperature and low temperature; has good elastic restoring force; has good acoustic performance of acoustic noise. Have good sound-absorbing effect; good chemical stability, no aging performance unchanged, thickness, density and shape can be processed according to user requirements.Main applications: short cotton is mainly made of glass wool felt and felt. It is used for heat insulation and sound insulation of buildings, heat preservation and sound insulation of ventilation and air conditioning equipment. Superfine cotton master
