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.

Fiberglass has a great application in the field of decoration. Fiberglass floor towels and fiberglass carpet towels are examples, so when you cut a PVC floor or PVC carpet, you will find a thin layer of glass fiber in the middle of the PVC. The glass fiber makes the surface of the PVC floor flat and effectively avoids the deformation of the PVC floor and carpet. This is why PVC floors and carpets with a fiberglass core do not deform and blister in flooring applications.
Here is the content list:
Characteristics of fiberglass
Various applications of glass fibers
1. The fiberglass is uniformly dispersed and the surface is smooth
2. Excellent bonding performance with coatings
3. Waterproof and weather resistance, long service life
1.The glass fiber veneer paper directly covers the surface of the inner wall, making the wall smooth and textured. Fiberglass joint tapes are used as joint tapes for wall panel joints and wall crack/hole repair. Coated fiberglass mats are coated with a CaCO3 compound on the fiberglass mats. The coated fiberglass mat is used as a decoration mat to directly cover the uneven wall surface to avoid falling off of the decoration layer. Coated fiberglass mats are a quick and easy solution for updating walls.
2. Fiberglass filter media is also widely used in the field of air filtration. One of the applications is to use glass fiber filter paper as the skeleton layer, and the primary filter layer is laminated with glass fiber paper. The laminate is the functional part of the filter element. The second filter application is the use of glass fiber filter paper towels in environmental engineering to chemically remove VOC gases.
3. Fiberglass mat, polyester fiberglass mat, and CaCo3-coated fiberglass are ideal wallboard covering materials. Using these materials instead of kraft paper to cover the surface of the wallboard can effectively improve the breaking strength of the wallboard, and at the same time endow the wallboard with excellent characteristics such as waterproof, fireproof, heat insulation, and mildew resistance. Proven, scratch-resistant, etc.
4. Fiberglass battery separator paper towel is the first choice for all battery rooms, used as a separator for lead-acid batteries.
5. Glass fiber black paper towels, glass fiber yellow paper towels, and coated glass fiber mats are used as insulation materials for the surface of insulation boards such as mineral wool boards and polyurethane boards, giving insulation boards excellent breaking strength, and other functional properties, such as Fire and waterproof.
6. The fiberglass roof is used as the core material of the bituminous membrane. Also used as reinforcement for waterproof coatings. Asphalt can quickly impregnate fiberglass roof tissue, which retains and reinforces asphalt.
All in all, fiberglass has many uses and is recognized as the most important choice in all industries.

Fiberglass is an inorganic non-metallic material with excellent performance. It is made of pyrophyllite, quartz sand, limestone, dolomite, boro site, and boro site as raw materials through high-temperature melting, wire drawing, winding, weaving, and other processes. The diameter of the monofilament is several microns to twenty microns, which is equivalent to 1/20-1/5 of a hair, and each bundle of fiber strands is composed of hundreds or even thousands of monofilaments. Fiberglass is usually used as reinforcing materials in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates, and other fields of the national economy.
Here is the content list:
Main features of glass fiber
Melting point: glass is a kind of amorphous, with no fixed melting point, it is generally considered that its softening point is 500~750℃
Boiling point: about 1000 ℃
Density: 2.4~2.76 g/cm3
When fiberglass is used as a reinforcing material for reinforced plastics, the biggest feature is its high tensile strength. The tensile strength is 6.3 to 6.9 g/d in the standard state and 5.4 to 5.8 g/d in the wet state. Good heat resistance, no effect on strength when the temperature reaches 300 ℃. It has excellent electrical insulation, is an advanced electrical insulation material, and is also used for thermal insulation materials and fire shielding materials. Generally only corroded by concentrated alkali, hydrofluoric acid, and concentrated phosphoric acid.
Compared with organic fibers, fiberglass has higher temperature resistance, non-combustibility, corrosion resistance, good heat insulation, and sound insulation, high tensile strength, and good electrical insulation. These characteristics make the use of glass fiber far more extensive than other types of fibers, and the development speed is also far ahead.
(1) High tensile strength and small elongation.
(2) High elastic coefficient and good rigidity.
(3) The amount of elongation within the elastic limit is large and the tensile strength is high, so the absorption of the impact energy is large.
(4) Fiberglass is an inorganic fiber, which is non-flammable and has good chemical resistance.
(5) Low water absorption.
(6) The dimensional stability and heat resistance are all good.
(7) Good processability, can be made into different forms of products such as strands, bundles, felts, and woven fabrics.
(8) Transparent and permeable to light.
(9) Good adhesion to resin.
(10) The price is cheap.
(11) It is not easy to burn, and can be melted into glass beads at high temperatures.
