Its chemical structure is composed of two morpholine rings connected by an ether bond, and this unique structure imparts many excellent properties to BMDEE. Specifically, the presence of morpholine rings gives them strong polarity and hydrophilicity, while the ether bonds enhance their chemical stability.

Parameters Value
Molecular Weight 242.35 g/mol
Density 1.05 g/cm³
Boiling point 290°C
Melting point -18°C

Physical Properties

BMDEE is a colorless to light yellow transparent liquid with a mild odor and is not easy to evaporate. Because its molecules contain multiple polar groups, BMDEE has good solubility and is compatible with a variety of solvents (such as alcohols, ketones and esters). In addition, its low toxicity also makes it safer and more reliable in practical applications.

Physical Properties Description
Appearance Colorless to light yellow liquid
Solution Easy soluble in water and organic solvents
Steam Pressure Extremely low

Chemical Properties

BMDEE has very stable chemical properties and can maintain good tolerance even under high temperature or strong acid and alkali environments. This is due to the synergistic effect of ether bonds and morpholine rings in its molecular structure. For example, during concrete curing, BMDEE can react slightly with minerals in cement to form a stable protective layer, thereby improving the erosion resistance of concrete.

In addition, BMDEE also exhibits certain catalytic activity, especially in epoxy resin curing systems, which can act as an efficient accelerator to accelerate the progress of cross-linking reaction. This characteristic has also made it widely used in the field of composite materials.


Application of BMDEE in rail transit construction

Improving concrete performance

Concrete is the foundation and one of the important materials in rail transit construction. However, traditional concrete often experiences cracking and peeling problems when facing harsh environments, which seriously affects the service life of the facility. The addition of BMDEE can significantly improve these problems, which are reflected in the following aspects:

  1. Enhance the resistance to freeze and thaw
    In cold areas, concrete is prone to damage due to repeated freeze-thaw cycles. BMDEE can reduce the risk of freeze-thaw damage by regulating the pore structure and reducing moisture infiltration. According to experimental data, the strength loss of BMDEE-added concrete after 100 freeze-thaw cycles was only half as high as that of the unadded samples.

  2. Improving corrosion resistance
    Rail transit facilities are often exposed to complex environments such as seawater erosion or industrial waste gas pollution. Hydrophilic groups of BMDEEA dense protective film can be formed on the concrete surface to prevent harmful ions (such as chloride ions) from penetrating, thereby delaying the occurrence of steel bar corrosion.

  3. Optimize mechanical properties
    The introduction of BMDEE can also improve the compressive strength and toughness of concrete. Studies have shown that after adding BMDEE in moderation, the compressive strength of concrete can be increased by 15%-20%, and the fracture toughness is also significantly improved.

Performance Metrics Ordinary Concrete Concrete with BMDEE
Number of freeze-thaw resistance 70 times 150 times
Compressive Strength (MPa) 40 48
Tenability Index 1.2 1.8

Improve construction conditions

In addition to improving the performance of the material itself, BMDEE can also optimize the construction process. For example, in hot weather, concrete may cause surface cracking due to moisture evaporation too quickly. The hygroscopicity of BMDEE can help maintain proper humidity, extend working hours and ensure construction quality. In addition, it improves the flowability of concrete and facilitates pumping and pouring operations.

Extend the life of the facility

Long-term stability is crucial for rail transit facilities. The addition of BMDEE can not only solve problems in short-term construction, but also ensure the safe operation of facilities from a long-term perspective. For example, after using BMDEE-containing concrete in key areas such as high-speed rail piers and tunnel lining, its design life can be extended from the original 50 years to more than 100 years.
