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:Is centrifugal glass wool board suitable for home use?
It can be easily broken and produce fine suspended particles. If the glass wool is of poor quality, you'd better use plastic bags or non-woven fabric to wrap it when using. So you must choose brand whose products are of good quality. Also if it is for the acoustics, it will do harm to the human body if inhaled into the lungs. So be sure to choose a renowable brand o centrifugal glass wool.
Q:What's the difference between glass wool board and rock wool board ?
In fact, it is very simple. Glass wool is processed from glass (silicon dioxide) , while rock wool is made from basalt or diabase through high temperature refining equipment, which are two completely different products. Hope it is helpful.
Q:What is the highest temperature that the fireproof glass cotton can resist?
It is certain that A level is the highest. A level indicates that it is non-combustible. Level B indicates that it is fire retardant. Rock wool can resist 800 ℃ and glass wool can resist 450 ℃. The hest perservation effect of matetials of B level is relatively better.
Q:Does rock wool refer to the glass wool?
Rock wool is not glass wool, ~ ~ ~ two kinds of products, appearance, price, performance are different, have obvious difference.
Q:What is the difference between high density glass wool board and stereoplasm rock wool board?
The main raw material of rock wool products is fine basalt rock. The basalt rock is made into inorganic fiber after meited under high temperature and processed in the high-speed centrifugal device. he rock wool board can be made into wool board and rock wool pipe shells.Technical characteristics of rock wool board are as follows.1, good thermal insulation property, mechanical property and fireproof performance.2, It has high the coefficient of acidity and better chemical stability and fiber durability.3, It has good sound-absorbing performance.Rock wool is widely used for thermal insulation in boilers and equipment pipelines of petroleum, chemical, metallurgy, textile industries. It is also used for thermal insulation and sound absorption of partition,suspended ceiling, inner wall and external wall in the construction industry.Rock wool board's main products and specifications are as follows.1, the density of rock wool board:80 -180kg / m3 2, the thickness of rock wool board :50mm-100mm 3, specifications of rock wool board :1000mm × 600mm. The thickness is 10mm-100mm; the length is 1m; width is 0.63m; density is 100-220kg and diameter is 27mm-1080mm.
Q:What are the standards of glass wool board?
The thickness of glass wool board are 0.7 mm and 0.5m m, and it will soon enter the thinner (eg 0.4mm) thickness process. Basically, a TFT- LCD panel needs two glass substrates, they are used for bottom glass substrate and the base plate of color filter. Generally, the supply proportion of liquid crystal plate assembling factory and processing factory of the color filter glass substrate by glass substrate manufacturing suppliers is about 1:1.1 to 1:1.3.
Q:Does rock wool board refer to the glass wool ?
The difference between rock wool and glass wool 1. same raw material, 2, same products performance, the unit weight of glass wool is lower than rock wool, less slag ball, low heat conductivity coefficient, good fiber tenacity, and the using temperature of rock wool is about 600 degrees centigrades, glass wool is about 260 degrees centigrades, 3, products application: glass wool is used for the thermal insulation parts below 200 degrees centigrades,such as construction or low temperature pipe thermal insulation, rock wool is used in thermal insulation parts under 450 degrees centigrades, such as high temperature heat pipe or electric power equipment thermal insulation.
Q:What environmental pollutions will be created during the production of glass wool?
The thermoset resin used in the production of glass wool contains various free formaldehydes which are harmful to the environment.
Q:What kind of glass wool pipe is this? Where is it sold?
The glass wool pipe is made of extra-fine glass wool. I do not know this brand. Maybe it is a korean brand.
