Molecular formula : (NH4)nε♦+2PnO3n+1 n<20 CAS No.: 68333-79-9 EINECS No.: 269-789-9 HS CODE: 2835.3990 Model No.: TF- 303, 304
Product introduction
Other name : polyphoφ∏sphoric acids ,ammonium salts$ Properties: Ammonium polypho♣≤sphate with short chain and low polymer€¶₹ization degree, PH value is neutral. ↓÷ Appearance : White powder o∏∞r lumps, easy to absorb water and goo÷ αd solubility. The water solution is •↓'clear.
Features
1. Lump solid, stable proper¥<•¶ty, convenient for transportation©♥★, storage and use ;
2. pH value is ne★ε∑×utral, safe and stable during productio'β±φn and use, good compatiblen↕≥×ess, not to react with other£α flame retardant and auxiliary ;
3. High P-N content, appropriate× ÷★ proportion, excellent synergist✘∏"ic effect and reasonab☆↓← le price.
Product Usage
Aqueous solution is u¥≤↓sed for the fire retardant treatment ©↓π.To prepare 20-25%P-N flame retardant, ≈♥used solely or together with≥ other materials in the fl¥ε✘Ωameproof treatment for textil →↕≥es, papers, fibers and woods☆∏♠∞, etc. To apply by autoclave, immerε<αsion or by spray both ok. If sπ≠♦←pecial treatment, it ca↕πn be used to prepare high-≥ concentration flameproof liquid to 5σελ×0% to meet the flameproof req€☆uirement of special ≠☆≠production.
Can be widely used in water-sol©£≈₹uble fire retardant c♦γ§×oating, but also used as a hβ£igh concentration of binary compound fertilizer, slow release fe★€₽rtilizer, ion-exchange age↕®δ nt and dispersants in mining industry"×♣¥.
Can be used for water based ×↔extinguisher.
