Acceptance points and common risks
- Use the temperature to focusUncorrosive materials do not represent long-term mechanical and antioxidant qualification.
- The paper is exposed for a long timeThe effects of packaging damage, deformation of the cylinder core and local heat accumulation have been observed.
- Fixed brake parametersChanges in membrane surface temperature on the same day may also require re-testing.

Project judgments and procurement conclusions
The key for high-temperature areas is not to ask how much zinc is resistant to heat, but to differentiate between the operating temperature of the medium, the temperature of the sub-membrane under the sun's radiation, the short-term construction temperature and the temperature of the container closure. The burning of the HDPE film should focus on the time of oxidation induction, carbon black dispersion and stress resistance cracking; long-term exposure systems also need to be specifically verified for UV, thermal oxidation aging and wind hardening.

Key parameters and quick judgement tables
| Source of risk | Procurement controls | Action on the ground |
|---|---|---|
| High UV exposure | Carbon black, UV retention rate, design life | Cover the soil or set up a protective layer as soon as possible |
| High-temperature liquid | Resin compatibility, long term temperature boundaries | Special confirmation by mediation |
| Hot containers | Packaging, rolling core, stack code restrictions | Windshield, check on the shipment |
| Hot welding | Testing of the membrane surface temperature | Avoid the midday dynamic mode |

Steps to landing
- Working conditions at the temperature
The system provides the environment, membrane surface, liquid and transport temperature respectively.
- Confirmed exposure period
Distinguish between construction exposure, periodic exposure and permanent exposure.
- Requesting long-term data
Verify the standard version, sample thickness and batch report.
- Developing a window for construction
The program is designed to be used for testing, shading and temporary load.
