The B1-level flame-retardant rating refers to the GB/T17591-2006 standard "Flame-Retardant Textiles." Based on the product's performance across multiple indicators—including calorific value during combustion, flame spread, peak heat release rate, and the fire growth rate index FIGRA—it is classified. Flame-retardant performance is classified into four grades: B3, B2, B1, and A.

 

Class A: Non-combustible material

A material that hardly ever combusts.

 

Class B1: Flame-retardant material

Flame-retardant materials have excellent flame-retardant properties. When exposed to open flames or high temperatures in air, they are difficult to ignite and do not spread rapidly. Moreover, once the ignition source is removed, combustion immediately ceases.

 

Class B2: Combustible Materials

Combustible materials have a certain flame-retardant effect. When exposed to an open flame or high temperatures in the air, they will immediately catch fire and burn, easily leading to the spread of a fire.

 

Class B3: Flammable Materials

It has no flame-retardant effect, burns extremely easily, and poses a significant fire hazard.

 

 

Flame Retardancy Performance Test Report A conformity assessment refers to the product quality inspection report issued by a nationally accredited testing organization after conducting tests on a product in accordance with the applicable national quality standards and using nationally prescribed testing methods.

 

 

Halogenated flame retardant and halogen-free flame retardant

 

 

To achieve a certain level of flame retardancy, textiles need to be treated with an appropriate dosage of flame-retardant agents. Flame retardants can be classified into halogenated flame retardants and non-halogenated flame retardants based on their chemical composition.

Halogen-based flame retardants mainly include bromine-based and chlorine-based types. These flame retardants work by capturing free radicals generated in the gas phase during combustion; at the same time, the gases they release can dilute flammable substances in the gas phase, thereby achieving a flame-retardant effect. However, during combustion, they produce large amounts of smoke, and the hydrogen halides released are highly corrosive. It is corrosive and can produce toxic, carcinogenic substances. Not only does it cause certain harm to human health, but it also has adverse effects on the environment.

Therefore, more environmentally friendly flame-retardant materials are now emerging as alternatives to halogen-based flame-retardant materials.

 

 

 
 

 

All-Degradable Flame-Retardant Wiping Cloth for Exploration

 

 

(1) It achieves flame retardancy at B1 level and is non-corrosive, stable against heat and ultraviolet radiation.

During operations such as welding, grinding, and spraying in enclosed spaces, as well as inspection and maintenance at nuclear power plants, wind farms, hydropower stations, military ships and submarines, and aircraft maintenance, the confined environment and the tendency to generate sparks make fires highly likely if the auxiliary materials and consumables have low fire resistance ratings. Moreover, the presence of mechanical oil stains in the environment further complicates matters—once a fire breaks out, it becomes extremely difficult to bring under control.

Tanzhu Technology Flame-Retardant Wiping Cloth, Under an open-flame test, it is difficult to ignite and will not burn continuously for more than 5 seconds. Once removed from the flame source, it will automatically extinguish without sustaining combustion, effectively helping to reduce the spread of fire.

(2) Pure viscose fully biodegradable material, free of harmful gases, and more environmentally friendly.

Made entirely from viscose, a fully biodegradable material whose raw material is plant roots and stems (glucose monomers).
