Difference between ceramic, mineral wool and glass wool

Ceramic fiber wool, rock wool and glass wool are becoming increasingly popular insulation materials. Do you know how to distinguish between ceramic fiber wool, rock wool and glass wool, do you know their performance characteristics and applications?

Differences in production processes

Ceramic fiber cotton is a fibrous lightweight refractory material whose main components are Al2O3 and SiO2. It is made by firing and melting hard clay, mainly consisting of kaolin and fired sapphire, and then blowing it with air at high pressure or rotating it with three rolls. form fibers of pure inorganic fibrous material.

Минеральная — это изысканный базальт в качестве основного сырья, высокотемпературное плавление, изготовление неорганических волокон с помощью высокоскоростного центробежного оборудования, а затем добавление специального связующего и пылевидного масла путем качания ленты для распространения войлока и изменения структуры расположения волокон с помощью специального оборудования, и, наконец, изготовление легких теплоизоляционных материалов путем отверждения и придания формы.

Glass wool is also an inorganic fiber, using silica sand, limestone, dolomite and other natural ores as the main raw materials, with some soda ash, borax and other chemical raw materials melted into glass. In the molten state, with the external force of blowing type piles into flocculent thin fibers, fibers and fibers of three-dimensional intersection, intertwined with each other, showing a lot of small gaps. This gap can be regarded as pores, so glass wool can be regarded as a porous material with good thermal insulation and acoustic characteristics.

Difference in characteristics

Glass wool is usually used in ambient temperature below 200℃ and mainly used to insulate general purpose buildings or low temperature pipes; mineral wool is usually used in environments above 500℃ and mainly used to insulate high temperature heat pipes or electrical equipment; ceramic fiber wool. It can be used at a temperature of 200℃, 500℃ or 1000℃.

Difference in product utilization

Glass wool is generally used for insulation parts below 200℃, mainly used for general building or low-temperature piping insulation; mineral wool is generally used for temperature in 500℃ insulation parts, mainly used for high-temperature heat piping or power equipment insulation; ceramic fiber wool can be used in both 200℃ low-temperature insulation, also can be used in 500℃ medium-temperature insulation, but also can be used in 1000℃ fireproofing; ceramic fiber wool can be used in both 200℃ low-temperature insulation, but also can be used in 1000℃ fireproofing.
