[knowledge] semi-enclosed fire protective clothing can prevent acid and alkali

Semi-enclosed fire protection chemical protective clothing is a protective clothing worn by firefighters when they enter the scene of a chemical dangerous goods or corrosive article fire or accident and perform fire extinguishing and rescue. The garment is made of modified pvc double-sided coated fabric, not only has anti-acid and alkali properties, but also has good flame-retardant performance and strong performance. Its technical indicators all meet the Q/02MKF001-2005 standard requirements.

a structural feature

1. One-piece semi-closed structure, except for bare face, the rest of the parts are sealed.

2. Gloves are detachably connected with snap rings, which not only ensure airtightness but also facilitate replacement.

3. All sewing seams are sealed with inner and outer sealing strips to ensure the sealing performance of the garment.

4. The entire chemical protection suit consists of a hooded bodysuit, chemical-proof gloves, and chemical-resistant rubber boots.

Second technical characteristics

1. The main performance: Anti-acid, flame retardant and other properties. It can be used for emergency rescue operations in organic media such as gasoline, acetone, and ethyl acetate as well as in corrosive liquids such as sulfuric acid, hydrochloric acid, nitric acid, phosphoric acid, and sodium hydroxide.

2. The main parameters

Anti-acid permeation performance: The fabric does not penetrate for 1 hour under 80% H2SO4, 60% HNO3, 30% HCI acid.

Alkaline penetration resistance: The fabric does not penetrate for 1 hour under 6.1 mol/L NaOH lye.

Flame-retardant properties: Damaged length ≤ 10cm, continuous burning time ≤ 5s; smoldering time ≤ 10s and no droplets.
