Application scope of SPD water-based foamed polyurea sound insulation insulation board

SPD water-based foamed polyurea sound insulation insulation board is a new environmentally friendly material. It combines the high strength, weather resistance and lightweight and thermal insulation properties of polyurea technology. It is widely used in construction, industry, transportation and other fields. The following is an analysis of its specific application scope and advantages:

1. Construction field

1. Building exterior wall insulation system

Application scenarios: exterior wall insulation layer for residential, commercial buildings, and public facilities.

Advantages:

High-efficiency heat insulation: The foamed structure forms closed-cell bubbles with low thermal conductivity, effectively reducing heat conduction and energy consumption.

Fire safety: Polyurea materials are resistant to high temperatures, have no droplets or low smoke when burning, and meet Class A fire protection standards (such as GB 8624-2012).

Strong weather resistance: anti-ultraviolet rays, anti-aging, adapt to extreme climates (such as high temperature, severe cold, and humidity).

Convenient construction: it can adopt spraying or pasting technology to bond firmly to the base layer and shorten the construction period.

2. Integration of roof insulation and waterproofing

Application scenarios: thermal insulation layer and waterproof layer of flat roofs and sloped roofs.

Advantages:

Thermal insulation and waterproofing two-in-one: The polyurea coating forms a dense waterproof film, while the foam layer provides thermal insulation performance and reduces the roof thermal load.

Cracking resistance: Good elasticity, can adapt to slight deformation of the base layer, and avoid cracking and leakage caused by temperature changes.

Lightweight: Compared with traditional concrete insulation layer, the weight is reduced by more than 50% and the roof load is reduced.

3. Indoor sound insulation and noise reduction

Application scenarios:

Residential household walls and floor slabs are sound insulation (such as apartments and hotels).

Cinemas, recording studios, conference rooms and other places with high acoustic requirements.

Advantages:

High-efficiency sound insulation: reduces air sound transmission and impact sound transmission (STC value can reach more than 50dB) by increasing material density and damping performance.

Environmentally friendly and non-toxic: water-based formula, free of volatile organic compounds (VOCs), comply with indoor air quality standards.

4. Moisture-proof and thermal insulation in basements and basements

Application scenarios: underground garage, civil defense projects, walls and floors of storage space.

Advantages:

Moisture-proof and impermeable: The polyurea coating seals the pores of the base layer, prevents moisture penetration, and avoids condensation and mold.

Corrosion resistance: Resist the corrosion of salt and chemical substances in groundwater and extend the structural life.

2. Industrial field

1. Industrial equipment insulation

Application scenarios: Insulation layer of boilers, pipelines, storage tanks, reactors and other equipment.

Advantages:

Energy saving and consumption reduction: reduce equipment heat loss and energy consumption (such as reducing heat loss by 30%-50% after steam pipeline insulation).

High temperature resistance: can withstand high temperatures above 150℃ (adjusted according to the formula), and adapt to industrial high temperature environment.

Resistant to mechanical damage: high surface hardness, wear resistance, impact resistance, and protect the equipment from external forces.

2. Cold chain logistics and warehousing

Application scenarios: wall and floor insulation of cold storage, refrigerated truck, fresh storage.

Advantages:

Low temperature stability: stable performance from -40℃ to normal temperature range, without brittleness or shrinkage.

Rapid construction: The spraying process can achieve seamless connection, reduce cold bridges, and improve insulation efficiency.

3. Anti-corrosion and insulation of chemical and petroleum pipelines

Application scenarios: Integration of anti-corrosion and insulation of offshore platforms, oil pipelines, and chemical storage tanks.

Advantages:

Anticorrosion properties: The polyurea coating is resistant to acid, alkali and salt corrosion, protecting the pipeline from chemical media.

Integrated design: The insulation and corrosion protection are completed simultaneously, reducing construction processes and costs.

III. Transportation field

1. Rail Transit Sound Insulation Barrier

Application scenarios: sound barrier structure along subways and high-speed rail.

Advantages:

Lightweight and high strength: Compared with traditional concrete barriers, the weight is reduced by 60%, reducing the load on the track structure.

Good durability: anti-ultraviolet rays, anti-aging, and service life can reach more than 20 years.

Beautiful and easy to maintain: customizable colors and shapes, easy to clean the surface, reducing long-term maintenance costs.

2. Sound insulation and noise reduction for cars and ships

Application scenarios:

The sound insulation layer of the car engine compartment, chassis and doors.

Sound insulation of ship cabins and engine cabins.

Advantages:

Shock and noise reduction: absorb vibration energy through the damping effect to reduce noise (such as 3-5dB reduction in car interior noise).

Waterproof and mildew-proof: Adapt to humid environments and avoid mold and deterioration of interior materials.

4. Application of special environments

1. Polar and high temperature buildings

Application scenarios: Arctic scientific research station, exterior walls and roofs of buildings in desert areas.

Advantages:

Extreme temperature adaptability: stable performance in the range of -50℃ to 80℃, without embrittlement or softening.

Resistant to wind and sand: The surface is dense, resists wind and sand erosion, and is suitable for desert environment.

2. Nuclear power plants and military facilities

Application scenarios: nuclear reactor containment and protective layer of military equipment.

Advantages:

Radiation shielding assistance: Combined with materials such as lead plates to provide additional radiation protection.

Impact Resistance: High-strength polyurea layer can withstand explosion shock waves and debris impacts.

5. Summary of advantages
