Material characteristics:
High temperature resistance: High-quality PVC welding screens usually add flame retardants or high-temperature resistant materials to withstand the high temperature and sparks during welding, and are suitable for multiple uses. Ordinary PVC may deform or damage at high temperatures, limiting its reuse.
UV protection: The ultraviolet rays generated by welding are destructive to the screen. Professional screens will enhance the UV protection coating to extend the service life.
Reusage conditions:
Appearance inspection: No holes, cracks, deformations or severe discoloration.
Functional testing: Ensure that the barrier effect is not weakened, such as being able to block sparks or strong light.
Cleaning and maintenance: Regularly remove attachments (such as welding slag) to avoid affecting transparency or structure.
Disposable use scenario
If the screen is damaged due to high temperature, impact or chemical corrosion during a single use, or the manufacturer clearly marks it as "disposable", it needs to be replaced.
Post-use inspection:
Damage assessment: Check for burns, perforations or deformations after use. Minor wear can be cleaned and reused. However, for safety reasons, major damage should be replaced.
Maintenance Notes: To extend the service life, slag and dirt should be removed regularly. However, avoid using irritating or corrosive cleaning products.
Safety first
Even if the appearance is intact, if the material ages (such as hardening or becoming brittle) after long-term use, there may be hidden risks. It is recommended to follow the manufacturer's guidance or industry standard replacement cycle.
