What is the difference between high-purity ceramic fiber blanket and ordinary ceramic fiber blanket? As the name suggests, high-purity ceramic fiber blankets have higher purity than ordinary ceramic fiber blankets. The main differences between high-purity ceramic fiber blankets and ordinary ceramic fiber blankets are raw material purity, production process, temperature resistance, mechanical strength, and application scenarios; In terms of price, high-purity models have higher costs due to complex processes, while standard models are more economical.

Application fields of high-purity ceramic fiber blanket and ordinary ceramic fiber blanket:


Pure needle punched blankets are mainly used in fields that require high material purity, high temperature resistance, and thermal insulation performance. For example, in the aerospace field, the insulation system used for aircraft, such as the insulation protection around the engine, can withstand the high temperature during engine operation and reduce the weight of the aircraft. In high-end industrial furnaces, such as those producing monocrystalline silicon, it can provide a stable high-temperature environment to ensure production purity.

The standard needle punched blanket has a wider range of applications and is more common. In the construction industry, insulation used for buildings can reduce indoor and outdoor heat exchange and play an energy-saving role. In terms of insulation for ordinary industrial equipment, such as external wrapping of pipelines and small reaction vessels, it helps to maintain equipment temperature and reduce energy consumption.

Is the sound insulation effect of glass wool better than that of insulation materials

Is the sound insulation effect of glass wool better than that of insulation materials? Whether it is industrial decoration or home decoration, insulation and sound insulation materials not only affect the indoor temperature, but also have a huge impact on the sound insulation effect during decoration. The sound insulation effect of glass wool in insulation materials belongs to the middle and upper reaches, especially in the isolation of medium and high-frequency noise (such as human voice, equipment operation sound, traffic noise), which has obvious advantages. It is a commonly used integrated material for sound insulation and thermal insulation in the industrial and construction fields.

Sound absorbing and noise reducing rock wool roll felt

Sound absorbing and noise reducing rock wool roll felt: Rosetexwool safeguards silent fire safety

In industrial production workshops, large equipment rooms, and building pipeline installation scenarios, noise pollution and fire safety have always been the core issues of concern for enterprises. When industrial equipment with high temperature and large vibration operates, it will produce harsh noise, which not only affects the physical and mental health of workers, but may also interfere with the surrounding environment; During pipeline transportation, the flow and vibration of the medium can also cause noise, and if there is a fire hazard, ordinary insulation materials are difficult to effectively prevent fire. The sound-absorbing and noise reducing rock wool roll felt launched by Rosewool Insulation Refractory Co.,Ltd provides dual protection of silence and fire prevention for multiple scenarios, thanks to its A-level fire retardant performance and glass aluminum foil steel wire mesh structure advantages. ​
