Q:What is the difference between anti-high temperature glass wool and ordinary glass wool?

Difference: High-temperature glass wool is made up of glass fibers and special high-temperature adhesive. It is yellowish with curing agent as the high temperature adhesive and with a small quantity of glue. While ordinary glass wool is dark yellow with ordinary resin adhesive as the binder.

Q:There is an engineering air-condition air duct which uses aluminum foil glass wool for heat conservation, supervor require that it should be added a protective layer made by glass fiber cloth. according to peremptory norms,

Aluminum foil layer itself is a protective layer, which has no need to be increased more protective layers, is using glass cloth for heat conservation layer, you can buy glass fiber cloth without aluminum foil protective layer. However, the protective layer of aluminum foil is really easy to damage, but its impact on air duct is not larger than water pipe, which is acceptable.

Q:Does rock wool board refer to the glass wool ?

same properities, glass wool belongs to glass fiber, and rock wool, rock and mineral raw materials such as short and thin fiber in fluffy shape.

Q:Are rubber and plastic thermal insulation material and glass wool in air conditioner energy-saving materials ?

They almost are.

Q:What harm dose glass fiber cotton do to human body?

We are glad to answer your questions.1 Glass wool damages human health 1 Lots of glass fibers float out during the construction or after the aluminium foil is damaged.The glass fibers may cause serious damage to air quality and human health. According to the lung biopsy for workers who contact glass fiber, there are dust-cell focus, mild hyperplasia of collagen, lung cancer and lung abscess in the lung tissue.People who contact glass fibers may suffer from conjunctivitis and keratitis which will develope into corneal opacity and local abscess when the situation worsens.When the fiber diameter and the length is similiar, the glass fiber can also produce similar toxicity and carcinogenicity with asbestos.2 it is not environmentally friendly and is forbidden to be used in the Olympic venues.In view of the environmental factors, Ministry of Construction and the Beijing Municipal Health Bureau released the relevant documents to regulate the use of glass wool.In line with environmental protection, International Olympic Committee prohibit the use of glass wool in Sydney Olympics and Beijing 2008 Olympic Games.3 it dose not save energy.The aluminum foil covering the glass wool breaks easily. Besides, glass wool has an open cell structure. once it is damaged, water vapor will enter and the wet resistance factor is 0, which means that the insulation effect is reduced, energy is wasted and operating costs increases.

Q:How about the sound insulation performance of glass wool felts?

The direct relationship between sound level and the density of glass wool. It has sound absorption penetrability, also can be wall.

Q:What's the necessary performance tests lass wool used for steel structure need to do?

Generally it doesn't need to do the experiment, but some party A will demand for thermal insulation test, you can ask the local supervisor for samples manual and show it to party A, there is no test on steel structure columns.

Q:What environmental pollutions will be created during the production of glass wool?

There are harmful health hazards in the exhaust gas during the production of glass wool, such as phenol, formaldehyde, and glass fiber dust. Glass wool is very small. If it is on the skin, it will be atingle and itchy. If it gets into lungs, it will be quite dangerous.

Q:What is the thermal insulation material of glass wool?

It is a cotton-like material which has advantages of low thermal conductivity, chemical stability, good sound absorption. The glass wool is an inorganic fiber which has a excellent welding performance. Glass wool which is a man-made inorganic fiber fiberizes melten glass, it is a insulation material that has advantages of corrosion resistance, thermal insulation and small bulk density. I tell you that it belongs to glass in terms of chemical composition: The thermal insulation material, glass wool belongs to glass fiber.

Q:How to use glass wool for filtering?

Buchner funnel, but not filter paper.
