巖棉是以精選的玄武巖為主要原料,經(jīng)高溫熔融加工制成的人造無(wú)機纖維。具有質(zhì)輕、導熱系數小、吸聲性能好、不燃、化學(xué)穩定性好等特點(diǎn)。它是一種新型的保溫、隔燃、吸聲材料。巖棉制品除具有一般巖棉所具有的特點(diǎn)之外,還具有防水、保溫、絕熱隔冷等性能,有一定的化學(xué)穩定性,即使在潮濕情況下長(cháng)期使用也不會(huì )發(fā)生潮解。
Rock wool is an artificial inorganic fiber made mainly from selected basalt and processed by high-temperature melting. It has the characteristics of light weight, low thermal conductivity, good sound absorption performance, non flammability, and good chemical stability. It is a new type of insulation, flame retardant, and sound-absorbing material. Rock wool products not only have the characteristics of ordinary rock wool, but also have properties such as waterproofing, insulation, thermal insulation, and cold insulation. They have a certain degree of chemical stability and will not undergo deliquescence even when used for a long time in humid conditions.
根據JISA9512-1979方法試驗,其憎水率在98以上。由于其制品不含氟(F-)、氯(Cl-),因而它對設備無(wú)腐蝕作用。經(jīng)*部天津消防研究所檢驗認定為不燃性材料,是建筑物、管道、貯罐、蒸餾塔、鍋爐、煙道、熱交換器、風(fēng)機和車(chē)船等工業(yè)設備優(yōu)良的保溫、絕熱、隔冷、吸音的理想材料
According to the JISA9512-1979 method test, its hydrophobicity is above 98. Due to the absence of fluorine (F -) and chlorine (Cl -) in its products, it has no corrosive effect on equipment. According to the inspection and certification of the Tianjin Fire Research Institute, it is an ideal material for excellent insulation, cooling, and sound absorption of industrial equipment such as buildings, pipelines, storage tanks, distillation towers, boilers, flues, heat exchangers, fans, and vehicles
巖棉用于建筑外墻.保溫巖棉板的三種絕熱方式:內絕熱、中間夾芯絕熱和外絕熱。
Rock wool is used for building exterior walls. There are three insulation methods for rock wool panels: internal insulation, intermediate sandwich insulation, and external insulation.
巖棉保溫材料是以精選的玄武巖為主要原料,經(jīng)后天融化后,采用*的四輥離心制棉工序,將玄武棉巖高溫溶體甩拉成4~7μm的非連續性纖維,再在巖棉纖維中加入一定量的粘結劑、防塵油、憎水劑,經(jīng)過(guò)沉降、固化、切割等工藝,根據不同用途制成不同密度的系列產(chǎn)品。 其中巖棉板是有一定強度的預制板材,而巖棉氈則是以卷式包裝而易于大面積安裝。兩種產(chǎn)品皆可按要求生產(chǎn)成不同的密度和厚度,并貼上各種不同的飾面材料進(jìn)行施工應用!建筑用巖棉板和巖棉氈廣泛適用于各種建筑物中的不同建筑結構:應用于鋼結構屋面、外護墻體、室內隔墻、吸音吊頂、浮設夾層地板等的防火、保溫、吸音降噪、防冷凝結露。低密度(40 - 80kg/m3)的巖棉板和巖棉氈尤其適用于鋼結構框架中間的填充,具有降低熱傳遞和吸收聲音等良好性能。
Rock wool insulation material is mainly made of selected basalt as the main raw material. After being melted, it adopts a four roll centrifugal cotton making process to shake and pull the high-temperature solution of basalt into 4-7 μ m discontinuous fibers. Then, a certain amount of binder, dustproof oil, and hydrophobic agent are added to the rock wool fibers. After sedimentation, solidification, cutting and other processes, a series of products with different densities are made according to different uses. Among them, rock wool board is a prefabricated board with a certain strength, while rock wool felt is packaged in rolls and easy to install on a large area. Both products can be produced in different densities and thicknesses according to requirements, and various decorative materials can be applied for construction! Rock wool boards and felt for construction are widely used in various building structures, including steel roofs, exterior walls, indoor partitions, sound-absorbing ceilings, floating sandwich floors, etc., for fire prevention, insulation, energy conservation, sound absorption and noise reduction, and anti condensation and condensation. Low density (40-80kg/m3) rock wool board and rock wool felt are particularly suitable for filling in the middle of steel structure frames, with good properties such as reducing heat transfer and absorbing sound.
巖棉板的應用范圍為廣泛,用于多種領(lǐng)域的防火保溫。巖棉的主要性能有保溫性能、隔音性能、以及防水性能這三大特點(diǎn)是比較突出的。在建筑防水中,防水巖棉板憑借優(yōu)越的防潮性能有主要的應用。生產(chǎn)廠(chǎng)家根據不同的用途對巖棉進(jìn)行加工制作,其工藝主要是采取在巖棉纖維中添加不同的化學(xué)劑,經(jīng)過(guò)沉降、固化切割等工藝來(lái)制作不同密度的巖棉產(chǎn)品。
The application range of rock wool board is wide, used for fire prevention and insulation in various fields. The main properties of rock wool include insulation, sound insulation, and waterproofing, which are quite prominent. In building waterproofing, waterproof rock wool board has a major application due to its superior moisture-proof performance. The manufacturer processes and produces rock wool according to different uses, mainly by adding different chemical agents to the rock wool fibers, and producing rock wool products with different densities through processes such as sedimentation, solidification, and cutting.
巖棉板是由涂層鋼板和玄武巖礦物等無(wú)機礦物加工成的纖維,經(jīng)人工復合而成的建筑板材,由于占主要成分的鋼板、巖棉是非燃燒材料,所以巖棉板應視為非燃燒體。巖棉板的耐火極限有他的判定條件。失去支持能力、失去完整性和失去隔火作用三個(gè)。非承重構架失去支持能力表現為自身解體或垮塌,非承重墻、隔墻本身具有分隔作用的構件,當出現穿透裂縫或穿火的孔洞、孔隙時(shí),表明試件的完整性遭到破壞。當巖棉板失去絕熱性時(shí),具有防火分隔作用的構件,平均溫度升到140攝氏度或超過(guò)初始溫度180時(shí),則表明試件失去隔火作用。
Rock wool board is a building board made by artificially composite fibers processed from coated steel plates and inorganic minerals such as basalt. As the main components of steel plates and rock wool are non combustible materials, rock wool board should be considered as a non combustible material. The fire resistance limit of rock wool board has its own criteria for determination. Loss of support, loss of integrity, and loss of fire isolation. The loss of support ability of non load-bearing structures is manifested by their own disintegration or collapse. Non load-bearing walls and partition walls, which have a separation function, indicate that the integrity of the specimen is damaged when penetrating cracks or fire holes or pores appear. When the rock wool board loses its insulation, the component with fire separation function, when the average temperature rises to 140 degrees Celsius or exceeds the initial temperature by 180 degrees, indicates that the specimen has lost its fire separation function.
