Q:Glass fiber, glass wool, what is the difference

It is made of glass ball or waste glass as raw material by high temperature melting, drawing, yarn, weaving and other processes made of its monofilament diameter of a few microns to twenty meters a few microns, the equivalent of a hair Of the 1 / 20-1 / 5, each bundle of fiber raw silk by hundreds or even thousands of monofilament composition

Q:What is the density of glass wool?

Glass wool, a man-made inorganic fiber, belongs to a kind of glass fiber. It is a spongiform material made through fibration of melten glass. It is an inorganic fiber whose chemical components belong to glass, having good formability, low bulk density, low thermal conductivity, good thermal insulation and sound absorption, corrosion resistance and chemical stability. For centrifugal glass wool whose thickness exceed 5 cm and unit weight is 16Kg / m3, the sound absorption coefficient of low frequency125Hz is about 0.2, and that of middle and high frequency is close to 1. When the thickness continues to increase from 5cm, the low-frequency sound absorption coefficient also increase gradually. When the thickness is greater than 1m or more, 125Hz low frequency sound absorption coefficient will also be close to 1. Thicknesses of acoustic glass wools often used in architectural acoustics are 2.5cm, 5cm, 10cm, and unit weights are16,24,32,48,80,96,112kg / m3. centrifugal glass wool whose thickness is 5 cm and unit weight is 12-48kg / m3 is usually used.

Q:What is the density of high-temperature glass fiber

Density 2.4 ~ 2.7g / cm3 Glass fiber is used as reinforced materials in reinforcing plastic. the biggest feature is strong tensile strength. standard tensile strength is 6.3 ~ 6.9 g / d,in a wet state 5.4 ~ 5.8 g / d. Density 2.54. Good heat resistance. the tensile strength remains unchanged even if the temperature reaches as high as 300℃. It is high duty electrical insulation material. It is also used for thermal insulating and fireproof. it is only corroded by concentrated?alkaline,hydrofluoric?acid and concentrated phosphoric?acid.

Q:How to construct when apply rock wool board to glass curtain wall?

Base treatment--Coat interfacial agent on both sides of rock wool boards and the side - hang vertical line and flip the controlling line- Paste rock wool boards with the adhesive- Plastering the first rendering coat mortar--Pressing the alkali-resistant glass fiber mesh in it-- Anchoring rendering coat mortar composite alkali-resistant glass fiber mesh--Plastering the second rendering coat mortar and press alkali-resistant glass fiber mesh into it-- Plastering the third rendering coat mortar

Q:How can I fix the glass cotton insulation board to the wall?

The method to fix the thermal insulation partitions to the wall: 1: metal components are buried in the wall, set separators (movable method), or side drilling in thick plates and embed them in wall(movable method, IKEA separators use the same method), or carpenter fixes and decorates in accordance with components(they can not be removed once fixed). They are strong and stable. This method is suitable for new masonry walls. 2: Drill wall and insert rebar to the wall, set separators (movable method), or side drilling in thick plates and embed them in wall(movable method, IKEA separators use the same method), or carpenter fixes and decorates in accordance with components(they can not be removed once fixed). This method is suitable for most of wall with separators on it. 3: Use expaned anchor bolts on the wall to fix slotted-angle shelvings, set separators (movable method), or carpenter fixes and decorates in accordance with components(they can not be removed once fixed). The disadvantage of this method is that slotted-angle shelvings are ugly, but books and other objects can be put there to cover the diagonal bracings. The advantage of it is good bearing capacity, is suitable for heavy items and decorations. 4: Buy finished products of iron bracket or special mounting bracket, cantilever bracket(commonly used in stores), drill walls and use plastic bolts or fix with wooden chocks and screws. Glass partitions can be used, the cost is slightly higher, beautiful, carrying capacity is not too high, strong variability (upper and lower adjustable baffle spacing). Glass partitions can be used, though they are a little bit expensive, and have relatively lower bearing capacity, they are beautiful and have strong variability(the interval between the upper and lower partitions can be changed).

Q:Are foam glass and glass wool the same?

Different.

Q:How many types of centrifugal glass wool?

Centrifugal glass wool board is centrifugal glass wool made by curing treatment after a certain strength plate products, whether in high or low temperature environment, it can maintain good thermal insulation and sound absorption properties, and it is mainly used for advanced architectural interior compartment, suspended ceiling, the thermal insulation of metal duct or wind box, studio room, machine room, etc. all are the noise reduction and absorption.

Q:The main application of glass wool

Glass wool insulation is mainly used for water pipes

Q:What are the differences between glass wool felts and rock wool board in terms of appearance, and how to distinguish them?

First, the color. environmental glass wool is while, while rock wool is dark.

Q:Which is more expensive between glass wool and rock wool?

Glass wool board is more expensive than rock wool, but it is lighter in volume-weight than rock wool, which has the advantages that it will not cause itching of skin if exposed to skin, and its color is relatively bright with good thermal insulation and sound insulation.
