Does water immersion in high temperature glass wool affect its performance?

Difference: The high-temperature resistant glass wool insulation material is lightweight, durable, and superior in thermal insulation performance composed of uniformly slender, elastic glass fiber and special high-temperature adhesive. It is widely used in the thermal insulation and thermal insulation of equipment and pipelines in electric power, petroleum, chemical industry, light industry, metallurgy and other industries.

The outer protective layer of the insulation structure can be selected according to the specific situation, white iron sheet, aluminum skin, stainless steel or plastered surface material high-temperature glass wool is composed of slender glass fiber, without slag balls, compared with other types of insulation materials, will not be broken due to immersion or rain, and its thermal insulation performance remains unchanged after drying (the insulation material has, hydrophobicity does not mean that the insulation material does not absorb water, but indicates the ability to drain the water it absorbs). High-temperature resistant glass wool: High-temperature glass wool insulation material is a lightweight, durable, and high-temperature insulation material with superior thermal insulation performance composed of uniformly slender, elastic glass fiber and special high-temperature adhesive.

Features: High insulation efficiencyThe fibers of high-temperature glass wool are uniform and slender, and the fibers are arranged perpendicular to the direction of heat transfer, so that they can effectively prevent the transfer of heat and reduce the loss of heat. The lightweight and lightweight high-temperature glass wool is extremely easy to install, and can be cut into any size according to your requirements with an ordinary paper cutter during construction.

The fibers that will not be broken and elongated evenly and elongated ensure that they are tightly intertwined with each other, so there is no need to worry about the position of a nail hole in the fixed place, and the common insulation material is elongated due to fiber disconnection after a period of vibration or after a period of use, resulting in a phenomenon that heat loss increases with the use time. The pH value of high-temperature glass wool is between 7-8, and its soluble chloride ion content is very small, which has no corrosive effect on equipment and pipelines. Compared with other types of thermal insulation materials, it will not be broken by immersion or rain, and its thermal insulation performance remains unchanged after drying (the thermal insulation material has, hydrophobicity does not mean that the thermal insulation material does not absorb water, but indicates the ability to drain the water it absorbs).

Healthy high-temperature glass wool insulation material is non-toxic and harmless to the human body. Common glass wool: Glass wool belongs to a category in glass fibers and is a man-made inorganic fiber.

Glass wool is a molten glass fiber, forming a cotton-like material, the chemical composition belongs to the glass class, is an inorganic fiberIt has good molding, small bulk density, thermal conductivity, thermal insulation, good sound absorption, corrosion resistance, and stable chemical properties. The sound absorption characteristics of centrifugal glass wool are not only related to thickness and bulk density, but also related to the covering material, structural structure and other factors.

In the construction application, it is also necessary to take into account the cost, beauty, fire prevention, moisture resistance, dust, aging resistance and other issues. Cut at will, antibacterial and mildew-proof, anti-aging, anti-corrosion, to ensure a healthy environment. It can be cut and molded at will.

Centrifugal glass wool is made of glass as the main raw material, and then mixed with other auxiliary materials in a certain proportion, and then sent to the glass furnace to fully melt, and the melted solution flows out through the leakage plate and enters the centrifuge. Driven by the high-speed running centrifuge, the high-speed operation of the centrifuge throws the glass into a glass stream, under the action of high-temperature and high-speed flame, the glass stream is further stretched into fibers, and then the atomization binder is applied, under the action of the negative pressure wind of the cotton collection mesh belt, the fiber attached to the resin binder is settled on the moving mesh belt, forming a uniform cotton felt, and then through the constant temperature curing oven, the curing process is completed, the product is finalized, and the product is cut after being cut into a predetermined product, and then packaged.

Rock wool products are a new type of lightweight thermal insulation material made of fine basalt as the main raw material, melted at high temperature, made of inorganic fibers by high-speed centrifugal equipment, and then added with special binders and dust-proof oil, paved with a swing belt and changed by special equipment. According to different uses, it can be processed into rock wool boards, rock wool seam felts, rock wool tube shells and other products.

Second: the product performance is different.

Glass wool has a lower bulk density, less slag ball content, low thermal conductivity, long service life and large fiber toughness than rock wool, but the maximum use temperature of rock wool is about 600 degrees Celsius, and glass wool is only about 260 degrees Celsius.

Three: the use of the product is different.

Glass wool is generally used for insulation parts below 200 degrees Celsius, mostly used for insulation of general buildings or low-temperature pipelines, rock wool is generally used for insulation parts with a temperature of 500 degrees Celsius, and is mostly used for insulation of high-temperature thermal pipelines or power equipment.
