Flame retardants spray

The acid process has three advantages over the alkaline process, ie, (/) higher yield of phosphine (60 vs 25%) (2) more pure gas for use in subsequent reactions (95 vs 40%) and (J) by-product phosphoric acid is relatively valuable and can be sold into a number of markets, eg, in the manufacture of fertilizers and flame retardants. There is no ready outlet for the mixture of phosphites produced via the alkaline route and additional processing by oxidative spray drying is needed to produce phosphates for sale (3). 

Each substrate was saturated or sprayed with binder or binder-flame retardant to attain a 40% dry add-on. The high loft polyester was tested using the MVSS-302 protocol as this type material often is utilized in applications requiring this test. The rando rayon was tested using NFPA-701 protocol, as this test is one of the most stringent used with nonwovens.

Other fibrous and porous materials used for sound-absorbing treatments include wood, cellulose, and metal fibers foamed gypsum or Portland cement combined with other materials and sintered metals. Wood fibers can be combined with binders and flame-retardent chemicals. Metal fibers and sintered metals can be manufactured with finely controlled physical properties. They usually are made for applications involving severe chemical or physical environments, although some sintered metal materials have found their way into architectural applications. Prior to concerns regarding its carcinogenic properties, asbestos fiber had been used extensively in spray-on acoustical treatments. 

APB solution can be sprayed on paper or the paper can be dipped into the solution to yield fire-retardant products. In addition to the cellulose, it has also been used as a flame retardant in polyurethane foam and epoxy intumescent coatings. 

Furniture fabrics are back-coated with non-slip finishes, often with polymer-based ones. The formulation may include thickeners and flame retardants. Back-coating is mostly achieved by nip-padding or using a doctor (squeegee) or by foam application or spray techniques (for a lower add-on). Another one-side application is rotary printing (screens with regular perforation). 

PYROBAN K Special represents an aqueous high temperature stable flame retardant. It is miscible with water in any concentration and can be applied to cloth etc., by spraying, dipping or any other means available at the plant. Thorough penetration is important for good results. 

Stir and mix thoroughly before applying. NO. 5 FABRIC FLAME RETARDER may be applied by brush, spray or dipping. In all cases, fabric should be completely saturated. 

Commercially, antimony trioxide (Sb203) is the most important compound of antimony. It is used primarily in the manufacture of flame-retardant materials. It is usually sprayed on or added to a fabric to make it flame retardant. 

Products and Uses Utilized in flame retardant coatings, sprays, fungicides, and pesticides for camping equipment and tent fabric coatings, insecticides, and additives.

Another series of experiment was devoted to the selection of the most favourable construction of the least incendiary flame-retarded polystyrene foam with respect to fire protection. Sprayed asbestos wool, mortar, aluminium sheet, asbestos slate, and fibreboard were used as outer covers. 5 dm of gasoline was ignited successively in iron trays of 0.3, 0.6, and 1.0 m then an additional 10 dm in the last tray. 

It was concluded from this series of experiments that the fire hazard of a building was not increased by a flame-retarded grade of polystyrene foam when covered with sprayed asbestos or mortar.

Zinc enhances the flame retardancy of triaryl phosphate in m-PPO, leading to the highest LOI values. Zinc powder, however, is coated with zinc oxide. Woik has shown that zinc oxide enhances the decomposition of m-PPO. Thus a zinc coating (zinc arc spray) is perfiaps more representative of the effect of zinc with triaryl phosphate than zinc powder, with the latter having a greater zinc oxide surface.
