Building curtain seal strip

Building curtain wall sealing strips are sealing materials specially designed for building curtain wall systems. They are used to fill the gaps between curtain wall structures to prevent external environmental factors such as water vapor, wind, sand and dust from penetrating into the building, while improving the building's airtightness, sound insulation and thermal insulation.

Raw material inspection: Strictly inspect the purchased materials to ensure that the materials meet the quality standards.

Production process control: Strictly implement the production process to ensure that each link meets the quality requirements.

Finished product inspection: Perform appearance inspection and dimension measurement on the finished product to ensure that the product quality meets the standards.

Performance testing: Perform performance tests such as high and low temperature resistance, aging resistance, and UV resistance to ensure that the product has stable performance in various environments.

  • Applicable scenarios:

Building curtain wall sealing strips are suitable for various building curtain wall systems, such as glass curtain walls, aluminum curtain walls, stone curtain walls, etc. It is widely used in building exterior wall sealing projects such as high-rise buildings, office buildings, and commercial complexes, and plays a role in waterproofing, windproofing, sound insulation, and heat preservation.

  • Installation method:

The installation method of building curtain wall sealing strips is flexible and diverse:

1. Paste installation: Paste the sealing strip on the sealing groove or joint seam of the curtain wall structure to ensure that the sealing strip fits tightly with the structure.

2. Clamping and fixing: Use clamping or fixing parts to fix the sealing strip on the curtain wall structure to ensure that the sealing strip is not easy to loosen or fall off.

3. Embedded installation: Embed the sealing strip into the sealing groove of the curtain wall structure, and then seal it with sealant to ensure the sealing effect.

  • Notes:

1. When installing the sealing strip, ensure that the surface of the curtain wall structure is clean, dry, free of oil and dust to ensure a good sealing effect.

2. The length of the sealing strip should match the length of the curtain wall structure to avoid being too long or too short, which will affect the sealing effect.

3. During the installation process, care should be taken to protect the sealing strip to avoid damage or deformation, which will affect the sealing effect.

  • FAQ:

1. Is the sealing strip weather-resistant?

- Yes, the building curtain wall sealing strip is usually made of weather-resistant materials, which can maintain stable performance under various climatic conditions and is not easy to age and deform.

2. Will the color of the sealing strip fade?

- The color of the sealing strip is generally specially treated, with a certain durability and not easy to fade. However, slight fading may occur after prolonged exposure to strong sunlight.

Sealing Strip Production Process

Raw Material Procurement
The company rigorously selects high-quality suppliers to procure rubber, plastics, and various additives that meet national and international standards, ensuring material quality.
Raw Material Inspection
Advanced equipment and a professional team are employed to comprehensively inspect raw materials, including their physical and chemical properties, ensuring they meet production requirements. Only materials that pass inspection proceed to the production phase.
Compounding and Mixing
Accurate compounding and mixing are conducted according to product formulation ratios. High-efficiency mixing machines ensure thorough blending of raw materials to achieve uniform consistency. The mixed materials undergo a maturation period to ensure material stability.
Extrusion Molding
Maturation-treated mixed materials enter the extrusion molding process. Different extruders and molds are used based on product shapes and specifications. Stringent control of parameters such as temperature, pressure, and speed ensures products meet design requirements in terms of size and appearance.
Vulcanization and Cooling
Products after extrusion molding undergo vulcanization to enhance their physical properties and durability. Vulcanization occurs under high temperature and pressure conditions using vulcanization machines to ensure uniform curing. Post-vulcanization, products undergo cooling to further stabilize performance.
Cutting and Processing
Cooled products enter the cutting and processing stage. Precision cutting and further processing such as edge trimming and hole punching are performed according to specific product requirements. During processing, strict control of dimensions and accuracy ensures products meet design specifications.
Surface Treatment
Processed products undergo surface treatment as required, such as spraying, impregnation, or bonding. Surface treatment enhances product appearance and improves properties such as corrosion resistance, waterproofing, and wear resistance.
Final Inspection
All finished products undergo rigorous final inspection. The company utilizes advanced testing equipment and a professional quality inspection team to comprehensively test dimensions, physical properties, chemical properties, etc. Only products that pass inspection are packaged and ready for shipment; non-conforming products are reworked or scrapped.
Packaging and Storage
Inspected and approved products proceed to packaging. Suitable packaging materials and methods are selected based on product characteristics and customer requirements to ensure products remain undamaged during transportation and storage. After packaging, products are stored in the warehouse awaiting shipment.
