Q:Which is more suitable for industrial pipe insulation: glass wool or rock wool ?
Glass wool can only be used in about 260℃, but the highest operating temperature of rock wool is about 600℃. It is easy to construct and install, and can be used for many years with good effect of energy conservation, suitable for small storage tanks and cambered surface with small surface curvature radius and equipments with irregular surface. Rock wool has low heat conductivity coefficient, usually used in thermal insulation places at 450℃. Glass wool has lighter unit weight, lower shot content and higher cost performance ratio than rock wool, so it is widely used in insulation of general buildings and low temperature pipes, building air condition piping insulation and wall sound absorption. While rock wool felt is a quality thermal insulation material with low heat conductivity coefficient. Rock wool felt, with excellent insulation property and low price, is widely used in insulation for high temperature heat pipelines or electrical equipments. While glass wool is usually used in insulation places under 200℃。 Suitable for pipes with medium and large diameter. Fiber has strong toughness. That depends on your need.
Q:Could centrifugal glass wool be treated as cold insulation material?
yes, central air conditioning is useful.
Q:Which is more effective in retarding fire, rock wool or glass wool? What is the difference between rock wool and glass wool?
The fireproof performance of these two all reaches A degree. Water absorption rate and heat conductivity coefficient of these two are basically the same. However, glass wool is cleaner than rock wool and rock wool is cheaper than glass wool.
Q:Does anyone clearly know about the construction technology of glass wool blanket, aluminum net and sound-absorbing wall?
1, the technological process: A layer of dry-laid asphalt felt→ wooden keel installation → install gypsum board → stick glass wool blanket → pave and nail a layer of glass fiber cloth→install aluminum net → fix aluminum net. 2. operation key points of construction methods, embed errosion prevention wooden bricks: During masonry construction, embed corrosion prevention wood bricks (40 × 60 × 60) while laying bricks, with horizontal distance of 400 to 500, and the vertical dimension of 400. I hope my answer can help you.
Q:Are foam glass and glass wool the same?
Q:What is the difference between red glass wool and yellow glass wool in terms of technical parameters?
Thermal insulation properties: Red yellow glass VS Yellow glass wool. Thermal conductivity (K): below 0.039 VS over 0.044; Resilience: good VS poor. Distribution: even VS uneven. Irritation: non-irritating VS irritating and cause itching of skin. Dust: without dust VS with dust. Shot content: zero VS non-zero. Red glass wool is an environmental-friendly material.
Q:How about the quoted price of glass wool board of 96kg?
Quoted market price. 1, Sheng Ming glass wool board. Weight: 96kg. The texture is glass fiber. Price: 300 RMB yuan. 2, Sheng Ze glass wool board whose texture is glass fiber. Specifications: 1.2mX2mX50mm. Price: 129 RMB yuan. 3, Li Jing glass wool board. Specifications: 2420 * 1220 * 25mm. The texture is glass fiber. Price: More than 159 RMB yuan.
Q:What advantages do thermal insulation glass fiber wool have?
1, Stability at high temperature. 2, It is in line with environmental-friendly RoHS with no toxicity and with fireproof capability. 3, Non-asbestos or glass fiber wool products are harmless to human body. 4, It is remarkable in thermal insulation effect with low thermal conductivity and low specific heat. 5, It is light in weight, good in flexibility and great in thermal shock.
Q:What are the features of glass wool decorative acoustic panel absorber suspended ceiling?
Features: light weight, sound absorption, thermal insulation, fireproof, beautiful. It can be used as thermal insulation material for suspended ceiling and interior decoration of theaters, hotels, auditoriums, studios, shopping malls, offices, industrial buildings, etc. to improve indoor voice clarity, reduce noise and improve environment.
Q:The difference between glass wool of 50mm and rock wool.
Glass wool belongs to one of the glass fiber. machine-made fiber cotton wool molten glass fibrosis cotton material belong to glass fiber. type, bulk density, low thermal conductivity, thermal insualtion, acoustic insualtion, anticorrosion, stable chemical performance. Rockwool is also called mineral wool. Use Guangde Shida rock wool and mineral raw materials to make fluffy short fine fibers. Basalt rock wool, pyroxenite, dolomite, iron ore, bauxite can be used to make matrix fiber by going through high temperature melting process and fibrosis.
