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.

Yuan Lei's Little Knowledge | Performance Requirements and Types of Fillers for Coatings

2024-06-12


Fillers in coatings are usually white or slightly colored pigments with a refractive index less than 1.7. It has the basic physical and chemical properties of pigments used in coatings, but due to its refractive index being similar to the film-forming material, it is transparent in coatings and does not have the coloring and covering power of coloring pigments. It is an indispensable pigment in coatings.

2024-06-04


In architectural coatings, commonly used mineral materials include barium sulfate, calcium carbonate, kaolin, mica powder, talc powder, quartz powder, silica micro powder, transparent powder, glass powder, wollastonite powder, etc. Reasonable application of various mineral materials can effectively improve or enhance the performance of coatings. Let's take a look at the application of different mineral materials in coatings.

Yuan Lei's Little Knowledge | Characteristics of Mineral Materials

2024-05-21


Mineral materials refer to the material products obtained by processing and transforming natural minerals (mainly non-metallic minerals) or rocks as the main raw materials, or minerals or rocks that can be directly used as materials and aim to utilize their main physical and chemical properties. This meaning mainly includes the following four aspects: first, natural minerals and rocks that can be directly utilized or processed to be utilized; Secondly, finished or semi-finished materials made mainly from natural non-metallic minerals and rocks through physical and chemical reactions; Thirdly, artificially synthesized minerals or rocks; Fourthly, the direct utilization targets of these materials are mainly their own physical or chemical properties, not limited to individual chemical elements.
