Steel Building Cavity PU Injection Line Project in China

Steel-Building Cavity Injection in China project reference: Controlled material delivery and cavity injection for the specified wall construction.

Project Reference and Configuration

Illustration notice. Process illustrations are not verified photographs of this installation.

Project reference basis. Figures and configuration details are reported in the supplied project brief. They are reference values for the stated application, rather than verified acceptance results or a guarantee for another installation. Confirm the source records, material, tooling, operating schedule and test method when assessing a comparable project.

This project reference describes controlled material delivery and cavity injection for the specified wall construction.

Configuration and numerical values are reproduced from the supplied project brief for discussion. Original production, inspection and acceptance records have not been verified; these values do not establish certification or performance for another configuration.

Equipment References in the Project Brief

The supplied brief lists the following equipment references. Model identities, quantities and the actual delivery scope follow the original equipment schedule.

1. High-Output Cavity Injection Machine: Stoichiometric ratio metering, timed shot dosing & high-pressure delivery
2. Multi-Zone Heated Hose Line (60m): Maintaining precursor chemical temperature and pressure across wall scaffolds
3. Long-Reach Cavity Injection Gun: Precision docking into wall injection ports with mechanical clean shut-off
4. Pneumatic Chemical Transfer Skids: Continuous chemical drum feeding to the primary proportioning unit
5. Master Automation PLC Control Cabinet: Complete recipe storage, injection timing, and pressure telemetry monitoring

Installation, training, warranty and service arrangements follow the project agreement; durations in this brief are references.

Project Reference Values

99.8%

Reference: Cavity-Fill

Project-brief reference; original records pending. The brief lists a 99.8% fill ratio and a 72% baseline coverage value. Confirm cavity geometry, inspection method and the original volumetric assessment.

0 reported defects

Reference: Sheet-Deformation

Project-brief reference; original records pending. The brief lists no detected bulging in the inspected 100 mm cavities. Confirm the inspected area and acceptance method; it is not a universal zero-deformation result.

1,000 m²/day

Reference: Daily-Application

Project-brief reference; original records pending. The brief lists 1,000 m² per working day versus a 300 m² baseline. Thickness, actual working hours, staffing and site conditions require production records.
