The latest price of roofing rock wool board
manufacturers - Rock wool board products are chemically stable and will not deliquesce even if used for a long time in humid conditions. Due to the addition of a hydrophobic agent, rock wool products almost do not absorb water. According to the
- method, the hydrophobicity rate is above
. Rock wool board products contain almost no corrosive ions such as fluorine and chlorine, so they have no corrosive effect on equipment. Among many insulation materials, Beijing rock wool board and rock wool pipe products have light bulk density, small thermal conductivity, and good thermal insulation properties. , non-flammable, wide operating temperature range, long service time and other outstanding advantages. It is estimated that every cubic meter of rock wool board products used as insulation material in industrial thermal equipment can save energy
- kilocalories
- hours, which is equivalent to saving
- tons of standard coal per year. For every ton of rock wool boards and rock wool pipes used by builders for insulation, at least one ton of oil is saved a year. Therefore, it is widely used in industries such as construction, petrochemical industry, shipbuilding, metallurgy, electric power, urban heating network protection, and agriculture

- Conventionally produced rock wool boards are divided into two types: machine-made rock wool boards and handmade rock wool boards. The equipment to produce handmade rock wool boards only costs tens of thousands of yuan, while the equipment to produce machine-made rock wool boards costs more than 100 million yuan. The equipment to produce hard rock wool boards requires at least 100 million yuan. The rock wool products produced by our company have complete specifications, stable quality, and are non-irritating to the human body. They are ideal thermal insulation materials for industry and construction, and are also good sound-absorbing and filtering materials.
- Scope of application of rock wool insulation boards
- Rock wool products are widely used in construction, petroleum, electric power, metallurgy, textile, national defense, transportation and other industries. They are ideal for pipeline storage tanks, boilers, flues, etc. It is an ideal material for heat insulation and sound insulation of industrial equipment such as heat exchangers, fans, vehicles and ships.
- Rock wool insulation board uses natural rock and blast furnace slag as the main raw materials, plus a certain amount of auxiliary materials. It is melted and blown at high temperature to produce fibers, which are then used to make rock wool products. The maximum operating temperature of rock wool can reach
℃. Rock wool boards, rock wool felts, rock wool pipe shells, rock wool granular wool, etc. made from it can withstand high temperatures and are suitable for insulation of industrial high-temperature equipment. , At present, rock wool is also widely used in the external wall insulation, fire prevention, and heat insulation of buildings.
- Before the construction of external wall insulation begins, the base surface of the wall is required to meet the construction requirements of the external insulation system. If it does not meet the requirements, the following inspections and treatments are required: If the wall is dusty, powdery, or dirty, it is required to be cleaned. If there is oil stain, it is required to clean it with detergent and wait for it to dry. If the surface layer is loose, it is required to remove it. If there is a leveling layer, It is required to check on site whether the bonding strength between the leveling layer and the wall meets the requirements.
- The maximum service temperature of rock wool board refers to the maximum temperature allowed for its long-term use. The softening point of rock wool board fibers is
-, and there will be no change after long-term use at
-.
- Hard rock wool board is called hard rock wool board because its hardness is higher than rock wool board. The so-called hardness actually refers to the density of rock wool board. The higher the density of rock wool board, the better. The hardness is relatively high. The hardness of normal rock wool boards cannot be higher than that of hard rock wool boards.
