How to Choose Fireproof Cloth for Blocking Welding Slag and Sparks?

When selecting fireproof cloth, we should choose based on our specific needs:

    1. For vertical use with lower performance requirements, you can opt for fiberglass-coated triple-proof cloth. Fiberglass is a flame-retardant material that does not burn itself, but the surface coating is made of PVC plastic, which only achieves a Class B flame-retardant rating. The advantage is its low cost.

    2. For horizontally catching welding slag, you should choose a Class A flame-retardant fireproof cloth. Since freshly fallen welding slag is still very hot, using Class B flame-retardant cloth may cause smoking or even ignite. If the fireproof cloth is used overhead, you can choose Class A flame-retardant silicon-titanium fireproof cloth. Silicon-titanium fireproof cloth is a high-temperature-resistant inorganic fiber with an SiO2 content exceeding 96%. Its softening point is close to 1,700°C, allowing for long-term use at 900°C. It can remain intact after working for 10 minutes at 1,450°C or 15 seconds at 1,600°C. The advantages are excellent fire resistance and moderate pricing.

    3. If there are heat-sensitive items below the welding operation, you should choose ceramic fiber sintered cloth with fireproof and heat insulation effects. Ceramic fiber sintered cloth is made by further processing ceramic fiber cloth to naturally volatilize organic matter, resulting in a fireproof and heat-insulating cloth. It ensures no discoloration or black smoke emission when used in high-demand environments.
