Vermiculite-Coated Fireproof Welding Blanket

Spark isolation for welding and cutting

This blanket is sewn and processed from vermiculite-coated ceramic fiber cloth or vermiculite-coated fiberglass cloth. It combines high-temperature resistance, insulation and weather resistance, with a temperature resistance range of 500 C to 1260 C, and is used in welding operations where sparks are generated to isolate spark spatter, slag and welding spatter and to form a protection for surrounding flammable materials, dangerous goods and decorative surfaces.

The blanket can be customised to the customer's requirement and fitted with handles, eyelets and pull ropes. Other refractory materials can be selected for special usage scenarios. The product is also known as a welding blanket, welding curtain, spark receiving cloth, spark receiving blanket, marine welding blanket or marine welding cloth.

Working condition suitability and restrictions

The blanket isolates welding spatter and does not have the ability to block continuous open flame burning. It is suitable for dry static protection and not for strong acid or alkali corrosion, liquid immersion, high-speed medium erosion or long-term high-temperature burning. 1260 C is the short-term tolerance temperature of the base material; the actual tolerance depends on the base material type and the working environment.

Usage precautions

• Cutting and processing release fiber dust; ventilate, wear dust-proof protection and dispose of waste under local environmental regulations.
• For spatter isolation only; the blanket cannot replace fire prevention and fire extinguishing devices.
• Inspect regularly and replace when damaged, carbonised, delaminated or detached.
• All technical data are for reference; users should test suitability and follow relevant safety regulations.
