Q:What kinds of fire retardant coatings are there in steel structures?
Because this type of ultra-thin fireproof paint coating, making use of thick and thin fire retardant coating for steel structure is greatly reduced, thereby reducing the total cost of the project, the steel structure has been effective fire protection, fire effect is very good.
Q:Protective clothing is glass cotton wool type
Rock wool, also known as asbestos, is a kind of mineral cotton. A fluffy short staple fiber made from natural rock and minerals. Rock wool is a kind of inorganic fiber made of natural rock, such as Xuan Wuyan, gabbro, dolomite, iron ore, bauxite and so on. It is made by melting and fibrosis at high temperature.
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:Is it dangerous to make mineral cotton mattresses?
You should see the mineral wool mattress, mineral wool is Lord palm mattress, adding mineral wool because of mineral materials with various physical properties under certain conditions, such as far infrared energy and electric energy, magnetic energy, new products, general quality products.
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:Why should the insulation board be spliced when it is installed?
The EPS plate shall be bonded in a vertical arrangement and the vertical seam shall be staggered along the line. Insulation board construction fault seam stitching truth with brick walls are brick seam is a reason for strong security.
Q:Fireproof rock wool board can be used as firewall?
You need to know what material the firewall is made of What are its standards and requirements? What's the function of it? When you know all about it, you won't take a piece of board to make a wall!
Q:What materials should be used for building energy saving? Why?
Energy saving materials are widely used in building energy saving materials development and promotion in China. They have significant social, economic and environmental benefits, with great potential. At present, China's common energy-saving insulation materials are mainly rock wool, glass wool, polystyrene foam, cement, polystyrene board, silicate composite insulation mortar.
Q:The classification of exterior wall insulation and its main categories
1, exterior wall insulation usually(1) external thermal insulation of plate;(2) polyurethane rigid foam exterior insulation;(3) polyphenyl granule external thermal insulation;(4) inorganic insulation mortar external insulation;This is divided into small categories, such as sheet insulation, polystyrene board, inorganic insulation, expansion of glass beads2, rock wool exterior wall insulation, if there are rock wool board belongs to plate insulation, good combustion performance, good heat insulation performance, but relatively waterproof, bad, higher prices.Thin plastering exterior wall insulation does not indicate insulation material.Polyurethane insulation has been mentioned above, but the construction is not very convenient, and the combustion performance is poor and the price is higher.Polystyrene particles are good in every respect, and the only disadvantage is that the combustion performance can not reach the grade A (A1)
Q:The difference between rock wool and mineral wool
By the above two concepts, we should compare the difference between rock wool and slag cotton.1., raw materials are different: to metallurgical slag or fly ash as the main raw material called slag cotton; basalt and other rock as the main raw material called "rock wool"".2. the coefficient of acidity of rock wool and slag cotton is also different. Rock wool acidity coefficient MK generally greater than 1.5, and even up to more than 2; slag cotton MK generally can only be maintained at around 1.2, it is difficult to more than 1.3.3. because of the difference between chemical composition and acidity coefficient of rock wool and slag cotton, they also show some differences in performance.(1) the difference of water resistance(2) difference of heat resistance;(3) difference in corrosion resistance
