Is it fiberglass or asbestos 50

Glass fiber (original name in English: glass fiber or fiberglass) is an inorganic non-metallic material with excellent performance, with a wide range of advantages, good insulation, strong heat resistance, good corrosion resistance, and high mechanical strength, but the disadvantage is brittleness and poor wear resistance. It is made of glass balls or waste glass as raw materials by high-temperature melting, drawing, winding, weaving and other processes, the diameter of its monofilament is a few microns to more than 20 meters of microns, equivalent to 1 20-1 5 of a hair, each bundle of fiber precursor is composed of hundreds or even thousands of monofilaments.

Glass fiber is commonly used as a reinforcing material in composite materials, electrical insulating materials and thermal insulation materials, circuit substrates and other fields of the national economy.

According to the ** you sent, it can be determined that it is the common chrysotile asbestos (white asbestos), not fiberglass; The diameter of glass fiber monofilament ranges from a few microns to more than 20 meters of microns, which is equivalent to 1 20-1 5 of a human hair, and each bundle of fiber precursors is composed of hundreds or even thousands of monofilaments, so it can be judged from the diameter of the monofilament that it is not glass fiber.

This should be fiberglass. You can check the ** of asbestos and glass fiber, asbestos looks obviously dirty, impure in color, and messy arrangement, while glass fiber is more smooth and neat.

Distinguish between glass fiber and asbestos: Glass fiber is an inorganic non-metallic material with excellent properties. The ingredients are silica, alumina, calcium oxide, boron oxide, magnesium oxide, sodium oxide, etc.

The main raw material of glass wool is glass, which is mixed with other auxiliary materials in a certain proportion and then sent to the glass melting furnace to begin melting. The molten solution is sieved through a drain plate to separate impurities and finally sent to a centrifuge.

The centrifuge is full of power. In advanced operations, glass is thrown into a thin glass stream by a rotational force. By processing with high temperatures and high-velocity flames, these fine glass streams will form rows of fibers.

At the same time, atomized adhesives are used. Due to the negative pressure wind of the polyester-cotton mesh belt, the chemical fibers adhered to the epoxy resin glue adhered to the moving mesh belt, resulting in a well-balanced cotton felt. Finally, the product is cured in a constant temperature curing oven and cut to predetermined specifications.

The cut product is packaged and ready for sale.

glass wool and rock wool.

There are the following differences: different raw materials and processes, different product performance. Glass wool has a lower bulk density, less slag ball content, and lower thermal conductivity than rock wool.

Longer service life and greater fiber toughness, but the maximum service temperature of stone wool is about 600 degrees Celsius.

Glass wool is only about 260 degrees Celsius. The purpose of the product is different. Glass wool is generally used for the insulation of general buildings or low-temperature pipes, while rock wool is generally used for the insulation of high-temperature heat pipes or power equipment.

Rock wool is also a kind of insulation material, which is different from fiberglass.

Cotton. It is an artificial light silicate with a soft texture, more stable chemical properties, good elasticity, acid and alkali resistance, no chalking, and better elasticity. Its main raw material is fine basalt.

After melting at high temperature, it is made into inorganic fibers, and then special binders are added to become a new type of lightweight insulation material after curing and molding. Rock wool can be made according to different uses: felt, strips, tubes, granules, boards, etc.; industrial applications for thermal insulation of nuclear power plants, power plants, chemical plants and large kilns; The building is used for exterior wall insulation, roof and curtain wall insulation and isolation belts; Ships are used in cabins, sanitary units, crew lounges and power rooms; Agriculture is applied to factory soilless cultivation of vegetables, fruits, and flowers.

Glass wool is a type of glass fiber, just like a man-made inorganic fiber. Its main raw material is quartz sand.

Limestone, dolomite, etc. These are natural ores that can be made with soda ash.

Some chemical raw materials such as borax are smelted into glass. In the whole state, the fibers will form a three-dimensional intersection with the help of external forces, so that they are intertwined with each other to present tiny voids. This gap in glass fiber wool is often called a gap, so it can be regarded as a porous material with good thermal insulation and good sound absorption.

The chemical classification of glass wool is glass, which is an inorganic fiber. It has good formability, small bulk density, excellent thermal insulation performance, especially corrosion resistance and stable chemical properties.

What is the difference between fiberglass wool and rock wool? First, the raw materials and process of glass fiber wool, the main raw material of glass fiber wool is glass, mixed with other auxiliary materials in a certain proportion, put into the glass furnace through high-temperature and high-speed flame processing, these glass streams will be formed - the fiber. At the same time, the atomization binder is used, and due to the negative pressure wind of the polycotton mesh belt, the chemical fibers adhered to the epoxy resin binder adhere to the moving mesh belt, resulting in a uniform cotton felt.

2. The difference between the hydrophobic properties of glass fiber wool and rock wool board 1. The hydrophobic performance of glass fiber wool is not easy to break due to soaking and rain, and it is easy to dry out spontaneously when it is soaked, and its characteristics are stable. 2. The hydrophobic properties of rock wool rock silk wool collapsed immediately after being soaked, and many characteristics were missing. 3. The difference between the service life of glass fiber wool and rock wool board 1. The service life of glass fiber wool is stable in the performance of glass wool, under normal circumstances, it will not be chalking and the performance will decline sharply, and its service life can reach 30 years.

2. Rock wool is easy to crush, after a period of time, the slag ball will fall off or even disintegrate, and its service life is generally about 10 years.

The production process of the two is different, the density of the two is different, the way of use of the two is different, the content of the ingredients of the two is different, and the quality of the two is also different.

Glass fiber wool is an inorganic non-metallic material with excellent performance, and rock wool products are made of high-quality basalt, dolomite and other raw materials. And there is a big difference in the material, and the use is also different.

The production methods, structures, uses, and efficacy between the two are all different, and the materials between the two are also very different, and they are used in different handicrafts at the same time.

Hello, I'm glad to answer for you, I'm sorting out the relevant information, I'll get back to you right away.

1。To be sure, glass wool has a negative impact on human health. In actual construction work, or after the aluminum foil is damaged, a large amount of glass fiber will float.

And this kind of glass fiber wool will definitely affect air quality and harm human health. Lung biopsy surfaces of workers exposed to fiberglass were accepted by the relevant medical institutions. The lungs contain fiberglass dust cell foci, mild collagen hyperplasia, lung cancer, and lung abscesses.

In addition, people exposed to glass fibers may also have conjunctivitis and keratitis and, if severe, corneal opacity and local abscesses. What's even more terrible is that once the particle size and length of the fibers are similar, glass fiber wool will produce similar toxicity and carcinogenicity to asbestos, and its harm is not optimistic. Fiberglass wool is a material that is forbidden in Olympic venues because it is not environmentally friendly.

The Beijing Municipal Health Bureau has also issued corresponding regulations. For the sake of health and environmental protection, the previous Beijing Olympics and Sydney Olympics were banned. It is forbidden to use glass wool as a thermal insulation material.

The inside of glass wool is an open-cell structure. The outer aluminum foil is very easy to break. Once damaged, water vapor can easily enter.

The wet resistance coefficient is 0At this point, the insulation effect will be reduced, which will waste energy and be equivalent to operation. Increased costs.

I hope mine can help you, if you are satisfied with my service, please give a thumbs up, I wish you all the best!

Glass fiber, or "glass fiber" for short, is a new material and metal replacement material that plays a reinforcing role.

Asbestos refers to silicate mineral products with high tensile strength, high flexibility, resistance to chemical and thermal attack, electrical insulation, and spinnability. It is a general term for naturally fibrous silicate minerals. It is restricted in use because it is harmful to the human body when it is mined and used.

The former is made by artificial technology, and the latter is natural.

Hello dear: Glad to answer for you. The way to distinguish asbestos and glass fiber is to burn it with fire, generally glass six will be softened, glass fiber because of its small diameter, it is easier to soften and shrink into small beads; The melting point of asbestos is more than 1,000 degrees, and ordinary lighters cannot burn. This is the most common method.

They are all harmful to the human body, especially when inhaled into the lungs.
