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.
Grade GF/A: For high-efficiency routine filtration, including waste water pollution detection, for filtered water, algae and bacterial culture, food analysis, protein filtration and radioimmunoassay of weak beta emitters, recommended for particulate matter in air pollution monitoring Gravimetry, stack sampling and adsorption, etc.
Grade GF/B: Used to retain fine particles, fast flow rate. Especially suitable for sample processing with high suspended fine particles in liquid clarification or particle quantification. It can be used for pre-filtration of fine particles before membrane filtration, as a stationary phase in LSC (liquid-solid chromatography), and for protein binding.
Grade GF/C: Standard filter paper for collecting suspended solids in drinking water, natural water and industrial wastewater. Quickly and efficiently clarifies aqueous solutions containing small to moderately fine particles. Widely used in cell harvesting, liquid scintillation counting and binding assays when higher loads are required.
Grade GF/D: A common membrane pre-filtration material that can be used with GF/B to provide a very effective graded pre-filtration protection for the membrane.
Grade GF/F: Commonly used for DNA binding, adsorption and purification, protein binding, and the effect of filtering fine precipitated proteins is obvious. The combination of GF/F and GF/D can be used as a pre-filter membrane to purify extremely difficult to clarify biochemical solutions, fluids and nucleic acids .
Grade GF10: Commonly used in roll filter membranes in automatic air filtration devices.

Glass fiber is an organic substance, which itself is not harmful to the human body. But fine fiberglass dust is breathed into a person's lungs. Because glass cannot be absorbed and decomposed at all, it will form deposits for a long time, which will cause occupational diseases similar to silicosis. Although the damage is not fatal, it will affect people's respiratory function. Contact dermatitis often occurs in glass fiber workers, and a few people Skin sensitization occurs, but the fibers themselves have not been proven to be allergens so far.
If it's just pure skin contact, there are generally no other problems, the main reason is that it irritates the skin to a certain extent.
The opposite of Glass fiber is an inorganic non-metallic material with excellent performance. There are many kinds. The advantages are good insulation, strong heat resistance, good corrosion resistance and high mechanical strength, but the disadvantages are brittleness and poor wear resistance. It is made of glass balls or waste glass through high-temperature melting, wire drawing, winding, weaving and other processes. The glass fiber is often used as reinforcing material of composite material, electrical insulation and heat insulation materials, substrate and other national economy fields.

Why is fleece used in fiberglassing.
1. It is a reinforcing material
In the process of GRG production, gypsum slurry and glass fiber are used alternately, layer by layer. The glass fiber helps to strengthen the firmness of the gypsum block and prevent the gypsum from being scattered after solidification.
2. It has high temperature resistance
It has been tested that when the temperature reaches 300°C, it has no effect on the strength of the glass fiber
3. It has high tensile strength
The tensile strength of glass fiber is 6.3~6.9 g/d in standard state and 5.4~5.8 g/d in wet state.
4.It has good electrical insulation
Glass fiber has excellent electrical insulation and is an advanced electrical insulation material. It is also used in heat insulation materials and fire shielding materials.
5. It is not easy to burn
Glass fiber can be melted into glass beads at high temperature, which meets the requirements of fire prevention and control in the construction industry.
6. It has good sound insulation
The combination of glass fiber and gypsum can achieve a good sound insulation effect.
7. It’s cheap
Regardless of the industry, cost control is the most important link, and products with high quality and low price will definitely be favored.
Well, the above are the seven advantages of why glass fiber can be widely used in the construction industry. Glass Fiber is a very good substitute for metal materials.

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.
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.
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.
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.
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.
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.
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.
