Yuan Lei Small Classroom | Introduction of New Exterior Wall Thermal Insulation Materials: Composite Magnesium Silicate

 


  

Composite magnesium silicate insulation material is a new type of insulation material in recent years, it is simple construction, good performance and soon be used in the construction industry.

 

  1, low thermal conductivity, good thermal stability

Compared with traditional thermal insulation materials such as asbestos, perlite, aluminum silicate fiber, etc., the heat transfer mode of traditional thermal insulation materials is convection through many capillary holes, and heat radiation exchange between surfaces, thus increasing greatly with the rise of medium temperature, and the loss will also increase a lot. However, the three-dimensional closed holes of magnesium silicate thermal insulation materials hinder the convection of gas and have the ability to fold and radiate heat, therefore, with the increase of medium temperature, the increase is very small, the characteristic of slow rise, the heat loss increases very little, and the thermal conductivity curve shows a gentle upward trend.

 

  2. Good mechanical properties

Magnesium silicate insulation material paste and profile two categories. The paste can be directly applied to the special-shaped equipment in cold and hot states, and after drying, it forms a closed microporous structure and a reticular fiber structure. The profiles have various specifications of tube shells and plates. The compressive strength is greater than 0.5Mpa, and the flexural strength is greater than 0.35 Mpa, which fully meets the requirements of the national standard "Code for Construction of Pipelines and Equipment.

 

 

  3. Convenient construction

Composite magnesium silicate thermal insulation materials can be processed into shell (plate) products of various specifications and sizes according to the needs of users, so that all kinds of pipelines and equipment have corresponding profiles, which brings convenience to construction, improves the sanitary conditions of construction personnel, and greatly improves the construction speed and quality. Moreover, the composite magnesium silicate thermal insulation material does not contain toxic and harmful substances and has no damage to the health of construction personnel and post operators, moreover, it has good waterproof performance and high compressive strength. Therefore, the loss during packaging and transportation and construction is small, thereby improving the overall economic benefits of the insulation project.

 

  4. Long service life

Composite magnesium silicate insulation material, not afraid of the sun, no powder, can be easy to use any special-shaped equipment and pipes. It has strong adhesion, anti-vibration, no cracking, no shedding, no deformation and other beautiful. The service life is more than 3 times that of traditional insulation materials, and the service life can reach more than 10 years.

 

  5, non-toxic, tasteless, does not pollute the environment, does not harm the human body, does not corrode the equipment

Composite magnesium silicate thermal insulation material is a new type of mineral and sepiolite synthesized by high quality calcium and silicon materials and corresponding auxiliary agents under dynamic hydrothermal conditions. It does not add surfactant, which does not cause corrosion to pipelines and equipment. It has good thermal stability at high temperature, does not produce harmful substances, does not split, does not pollute the environment, and is harmless to human body.

Different applications and specifications of washed kaolin and calcined kaolin

2024-01-31


Kaolin is a non-metallic mineral, which is a kind of clay and clay rock mainly composed of kaolinite clay minerals. Because it is white and delicate, also known as white earth. It is named after Gaoling Village, Jingdezhen, Jiangxi Province.

Barium sulfate is based on barite as the main raw material, through beneficiation, ore washing, crushing and other processes. Barium sulfate has a hardness of 3~3.5 (Mohs) and a specific gravity of 4.3~4.7. It has the characteristics of high specific gravity, low hardness and brittleness. Barite is almost insoluble in water, ethanol and acid, soluble in hot concentrated sulfuric acid. With the development of some high-performance barium sulfate products, the application field of barium sulfate is constantly expanding.
