    Fiberglass membranes are manufactured from 100% borosilicate glass fibers and include binder-free, chemically inert and binder-containing types. The purpose of adding binder is to enhance the mechanical strength of the glass fiber membrane. It is mainly used to filter coarse particles (such as macromolecular substances, dust). In order to avoid chemical reactions with the filtered substance, glass with inorganic binder is used when filtering organic substances. Fiber membrane, choose glass fiber membrane with organic binder when filtering inorganic substances. This depth filter membrane has the characteristics of fast flow rate, large load capacity and extremely fine retained particles, which can reach the range of submicron particles. The glass fiber membrane can withstand a temperature of 500°C, and can be used for specific gravity analysis and high-temperature gas filtration that require ignition.

Fiberglass is not made of glass.

Glass fiber is made of pyrophyllite, quartz sand, limestone, dolomite, boronite, and boronite as raw materials through high-temperature melting, wire drawing, winding, weaving and other processes. Its main components are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc. According to the alkali content in the glass, it can be divided into alkali-free glass fibers (0% to 2% sodium oxide, which belongs to aluminum Borosilicate glass), medium-alkali glass fiber (sodium oxide 8% to 12%, which belongs to boron-containing or boron-free soda-lime silicate glass) and high-alkali glass fiber (more than 13% sodium oxide, which belongs to soda-calcium silicate glass) silicate glass).

Fiberglass is an inorganic non-metallic material with excellent performance. There are many kinds. Its advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength. Difference. The diameter of its monofilament is several microns to more than 20 microns, which is equivalent to 1/20-1/5 of a hair, and each bundle of fiber precursors is composed of hundreds or even thousands of monofilaments. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields.

Fiberglass is a glass material similar to the glass in our windows or the glasses we use to drink our favorite beverages. In modern life, the application of glass fiber can be seen everywhere. People know it differently. The best thing about fiberglass is that it is durable, unbreakable, very strong, and lightweight.

• Sound-absorbing applications of fiberglass

Production of glass fibers

From the manufacture of glass fibers, the glass is heated until it begins to melt and melt. It is then further forced through the ultrafine pores. This gives us very fine glass filaments, down to the point of being measured in microns. This is the basis of how fiberglass can serve such a variety of uses. These filament threads are flexible and can be molded into a variety of complex shapes for many different applications.

Application of glass fiber

Fiberglass becomes a widely used material in all industries. In addition to being an excellent insulating material, fiberglass is also very cost-effective.

In our daily life, FRP products are used everywhere: subway bodies, auto parts, medical devices, ships, furniture, structural parts for construction and industrial projects, FRP pipes, etc. Why are the surfaces of these FRP products so flat and smooth? The use of fiberglass as the skin material for these products is a key reason.

Sound-absorbing applications of fiberglass

Fiberglass panels are used in building and decorative acoustic panels. After being coated with calcium powder, it is used as the surface layer of thermal insulation materials such as PU and rock wool boards. Fiberglass board has the advantages of being fireproof, waterproof, and mildew proof, smooth surface, uniform fiber dispersion, good weather resistance, and long service life. It is an ideal acoustic decorative material for residents and public areas.

Fiberglass panels are produced with unrivaled formulations and processes, and the thickness of fiberglass panels can reach 8mm to 10mm, and a layer of porous structure gives fiberglass panels a unique combination of sound absorption. At the same time, glass fiberboard has the characteristics of heat preservation, heat preservation, and fire prevention. Coupled with the excellent properties of stiffness, lightweight, bendability, and ease of cutting, further processing, and installation of fiberglass panels are very easy and simple. All these properties make fiberglass panels an ideal material for improving the acoustic environment, reducing heat loss, and making buildings fire-resistant.

Fiberglass insulation is one of the most popular ways to keep your home warm. Since it's inexpensive, easy to find, and very dense, you can't go wrong with padding your walls. However, it's very squishy, so you might be a little confused about how to cut it. This is a very abrasive material that requires a sharp blade and some safety gear such as a dust mask and glasses. However, with some basic techniques, you can cut insulation board safely and efficiently.

1. Measuring insulating materials

   Choose a piece of plywood that is at least as wide as the fiberglass board. Place it on a flat surface so there is enough room to spread out the fiberglass. The plywood doesn't have to be too big, just make sure it fits underneath the part you're cutting. [
   

   Choose a sturdy piece of material, such as a piece of old plywood

   You can put plywood on the floor for protection.

   Avoid cutting bare surfaces such as concrete.

2. Wear cut-resistant gloves and other protective clothing. Fiberglass insulation is skin irritating, wear long pants and a long-sleeved shirt. Then, put on gloves, and some also wear disposable coveralls to prevent the insulation from spreading onto their clothing.

   If part of your skin is exposed, apply some baby powder on it. The powder prevents glass shards in the insulation from sticking to the skin.

3. Wear a dust mask and safety glasses for protection. A regular N95 cloth dust mask will do just fine, if the mask you're using doesn't cover your eyes, buy separate glasses. Wear safety gear whenever cutting insulation.

   The dust released by the insulation is harmful and can aggravate breathing problems such as asthma.

   If you can, work outside so that dust doesn't settle in your home.

4. Unroll the insulating paper face down. Fiberglass insulation is rolled into a roll. Place the roll over the edge of the plywood. Then, push it through the plywood. Spread out just enough to make the cut you want to make.

   Most insulation has a paper backing on one side. It's usually easier to cut the paper last, and the backing keeps the insulation clean when you unroll it.

5. Use a tape measure to determine where you will cut the insulation. Start by measuring where you plan to install the insulation. Plan to cut the insulation 1 inch (2.5 cm) larger than the insulation on all sides. Because fiberglass insulation is flexible, it can be tucked into tight places. The extra length will help it stay in place.

6. Mark the measurements on the insulator with a permanent marker. Use a tape measure to transfer the measurement to the insulator. Measure along both sides of the insulation, making small marks to indicate where you plan to cut.

   If you roughly cut the insulation to approximate size, you don't need to take any additional measurements. If your goal is a precise cut, you can use a piece of sawdust to make a straight cut in most cases.

The role of Black fiberglass

Black fiberglass is compounded on a glass wool board, which is a special material for heat preservation, sound absorption, and noise reduction. It acts on the lining of the glass wool air duct, absorbs the noise of the air duct system, reduces the loss of heat and cold on the air duct wall, and can meet the requirements of reducing energy consumption. requirements, greatly improving the indoor acoustic environment quality. It is especially suitable for environments with high mute requirements to improve sound quality and speech intelligibility. Such as high-end hotels, office buildings, clubs, and so on.
