Q:How to use glass wool for filtering?
It depends on the filtering materials, if the solid particles are large, you can directly use ordinary funnel but not filter paper, if solid particles are small, you can use filter paper, you can try to use a small amount of filtering materials, and decide in accordance to the filtrate state, the trial is necessary and you will know after lots of trials.
Q:whether the sound insulation is asbestos good or the glass wool good?
Because the main function is the fireproofing), sound absorption cotton belongs to asbestos, but match up with the installation (glass fiber cloth, and we in real life (in fact, we need the material with good sound insulation
Q:Which one among polystyrene boards, rock wool boards and glass wool boards is the best materials for external wall thermal insulation?
Polystyrene boards are better in terms of external wall thermal insulation materials but now polystyrene boards are not allowed to use. Rock wool and glass wool can be used, but they need good waterproofing treatments.
Q:Which has better effect of sound absorption, glass wool or rock wool?
Almost the same, no significant difference. You can send me message if you have some trouble.
Q:Which one has better noise absorption performance, the mineral wool or the glass wool?
And make it applied to spaces meet the requirements (for example conference rooms require clear voice). Glass wool only absorbs sound over 1500HZ. For example, in order to let the sound field to achieve more pleasant effect, sound-absorbing wool (mineral wool, to remove the noises of people in the waiting room (which is intermediate frequency). Professional sound-absorbing boards can absorb the chosen sound according to which part of sound you need. Curtains are ordinary sound-absorbing matter and absorb only 30%. Performance halls require the sound to reverberate enough but it should not be too long while KTV require the sound appealing.
Q:Which thermal insulation materials are the best for air-conditioners? Is it rubber and plastic, PEF or glass wool?
Copper contains rubber and plastic. PEF and glass wool are both suitable, but glass wool is not recommend for its poor waterproofing performance, you'd better use rubber and plastic! You can select them with appropriate thickness according to your local winter temperature, or else it will be frozen in winter for it is too thin.
Q:What are the requirements for the filling thermal insulation material of glass wool?
Q:how to get rid of the fur of the glass wool on the hand?
Stick it out with tape medical tape, rheumatism paste tape, and scotch tape.
Q:how to choose external wall insulation materials for glass wool?
Glass wool insulation materials insulate medium and low temperature. it belongs to A level fireproof materials and non-combustible. the use temperature of glass wool insulation material is-120 ℃ -400 ℃, used in construction, petrochemical, power, metallurgy and other fields of thermal insulation, sound absorption. Glass wool glass fibers is a man-made mineral fiber, a kind of glass fiber. Glass wool is molten glass that undergoes fibration process, cotton-like material. it is a good shaped inorganic fiber with small volume density, low thermal conductivity, thermal insulation property, sound-absorbing properties, corrosion resistance , chemical stability.
Q:What's the difference between the rock wool and glass wool?
Glass wool belongs to a category of glass fiber, and is a kind of man-made inorganic fiber. Taking quartz sand, limestone, dolomite and other FIR stone as main raw materials, and is melted into glass after mixed with some pure alkali, sodium borate and other chemical raw materials. In melting state, transfer them into flocculent fibers under the effect of external force, fiber and fiber are in three-dimensional crossing and winded with each other, presenting many little gaps. The gaps can be regarded as air voids. Therefore, glass wool can be regarded as porous materials, it has good heat insulation and sound absorption performance. Glass wool is a kind of spongiform material shaped by making melten glass fibering, it's chemical content belongs to glass and is a kind of inorganic fiber. It has good molding, small bulk density, low thermal conductivity, good thermal insulation and heat insulation, good sound absorption, corrosion resistance and stable chemical performance. Rock wool is artificial light silicate, not the continuous flocculent fiber material, soft texture, good chemical stability, acid and alkali resistant. Not brittle or pulverization, good elasticity, it can be heat insulation, sound insulation in projects.
