High Temperature Resistance Phase II Ammonium Polyphosphate/APP Flame Retardant

Category: Chemicals/Inorganic Salts/Other Inorganic Salts
Company: Jiangxi Dstone Minerals Technology Co.,Ltd.
Product Description: EINECS 269-789-9Ammonium Polyphosphate (APP) is primarily utilized as a highly efficient core component of intumescent flame retardants (IFR). This represents its most critical and widely adopted application across industries. Flame Retardant Mechanism When exposed to high temperatures, APP undergoes thermal decomposition to generate phosphoric acid and polyphosphoric acid. These decomposition products initiate two key protective reactions: They promote the dehydration and carbonization of polymer materials, forming a dense, intumescent char layer on the material surface. This char barrier effectively isolates oxygen and heat transfer, preventing further combustion of the underlying substrate. Simultaneously, non-flammable gases are released during decomposition, which dilute the concentration of combustible gases in the surrounding environment. Through the synergistic effect of physical isolation and gas dilution, APP achieves superior flame retardancy, inhibiting flame spread and reducing smoke generation. more>

Category: Chemicals/Inorganic Salts/Other Inorganic Salts
Company: Longxilong New Materials (Liaocheng) Co., Ltd.
Product Description: Product Name: Ammonium PolyphosphateAlias: Polyphosphoric Acid Ammonium SaltMolecular Formula: (NH4,H)n+2PnO3n+1CAS NO.: 68333-79-9Ammonium polyphosphate, also known as polyphosphoric acid ammonium salt, is a mixture of ammonium orthophosphate and various ammonium polyphosphates. The polyphosphates present mainly include ammonium pyrophosphate, ammonium tripolyphosphate, and ammonium tetrapolyphosphate, with longer-chain polyphosphates existing only in small amounts. It is highly soluble in water, with solubility greater than that of ammonium orthophosphate, and can chelate metal cations, keeping them in solution.PreparationIt is produced by reacting superphosphoric acid with ammonia or by dehydrating ammonium orthophosphate. Thermal process phosphoric acid containing 76% P₂O₅ is neutralized with ammonia at 0.17–2.07 MPa and 185–215°C to yield ammonium polyphosphate containing 16%–18% nitrogen and 59%–61% P₂O₅, of which 43% of the P₂O₅ is ammonium orthophosphate, 54% is pyrophosphate, and 2%–3% is long-chain polyphosphate. When preheated wet-process phosphoric acid containing 54% P₂O₅ is used, 30% of the P₂O₅ in the resulting product is ammonium polyphosphate.ApplicationsAmmonium polyphosphate is used not only as an ingredient in various fertilizers but also as a key chemical for extinguishing forest and mountain fires, as well as a fire-retardant impregnating agent for wood.An ammonium polyphosphate solution containing 11% nitrogen and 37% P₂O₅, produced from thermal process superphosphoric acid, is used as a primary chemical for extinguishing forest and mountain fires and as a fire-retardant impregnating agent for construction wood.A base solution of ammonium polyphosphate containing 10% nitrogen and 34% P₂O₅, made from wet-process phosphoric acid, is used as a raw material for formulating various grades of liquid compound fertilizers.Packaging:Standard packaging is 25 kg/bag.

China Steel Reinforced Polyethylene Composite Pipe with Perforated Web - China Supplier
Steel Reinforced Polyethylene Composite Pipe with Perforated Web
Negotiable
Category: Others
Company: Sichuan Dongtai Pipe Industry Co., Ltd.
Product Description: Research and manufacturing of perforated steel strip polyethylene composite pipes for over 20 years1) For Cold Water Use Perforated Steel Strip Polyethylene Composite PipeThe perforated steel strip polyethylene composite pipe is a composite pipe that uses a perforated pipe welded from cold-rolled steel strip as the reinforcing skeleton and is combined with thermoplastic plastic. Due to the introduction of the reinforcing skeleton, the heat resistance and strength of the pipe are significantly improved. In terms of process, this product introduces an adhesive layer between the steel strip and polyethylene, and uses argon protection during steel strip welding to prevent oxidation of the molten steel during high-temperature welding. This solves the problem of water channeling in composite pipes, making the performance of the composite pipe even better.1. Has higher rigidity and impact resistance than plastic pipes, with a low expansion coefficient and creep resistance similar to steel pipes.2. Double-sided anti-corrosion, with the same anti-corrosion performance as plastic pipes, and is corrosion-resistant. Operating temperature is increased.3. Low thermal conductivity.4. Smooth inner wall, no scaling, head loss is 30% lower than that of steel pipes.5. Pipe connections use electrothermal fusion, a mature technology, with a wide variety of pipe fittings.6. Lightweight, easy to transport and construct.7. By adjusting the thickness of the steel plate and plastic, pipes of different pressure grades can be manufactured. It is very convenient to change the parameters of the reinforcement to produce pipes of various pressure resistance levels.8. Using plastics with high temperature resistance, such as heat-resistant PE-RT polyethylene, random copolymer polypropylene (PP-R), etc., can produce temperature and pressure resistant pipes.9. High overall reliability of the pipe, with a service life of up to 50 years under normal conditions.   2、For Hot Fluids Perforated Steel Strip Heat-Resistant Polyethylene (PE-RT) Composite Pipe (Dongtai Pipe Industry)This product uses a perforated pipe welded from cold-rolled punched steel strip as the reinforcing skeleton and heat-resistant polyethylene (PE-RT) as the main material. Due to the introduction of the reinforcing skeleton and heat-resistant polyethylene (PE-RT), the pressure resistance and heat resistance of the pipe are significantly improved. This allows composite pipes originally only suitable for low-temperature (≤40°C) water supply to be used for hot water transportation, secondary heating pipelines, and pipelines in chemical and pharmaceutical industries for transporting high-temperature media.3) Application Areas1、Chemical Industry: Process and discharge pipes for transporting corrosive gases, liquids, and solid powders in industries such as acid, alkali, salt manufacturing, petroleum, fertilizers, pesticides, pharmaceuticals, chemicals, mining, rubber, and plastics.2、Oil and Gas Fields: Gathering and transportation pipelines for oil-containing wastewater, gas field wastewater, oil-gas mixtures, and polymer solution reinjection in oil wells, as well as secondary and tertiary oil recovery and gathering process pipelines.3、Mining: Slurry, tailings, ventilation pipes, and engineering pipes.4、Textile, Printing, and Paper Industries: Process distribution and discharge pipes for transporting corrosive media.5、Municipal Engineering: Urban building water supply and drainage, drinking water, and hot water return transportation.6、Non-Ferrous Metals: For transporting corrosive media in non-ferrous metal smelting.7、Agriculture: Deep well pipes, filter pipes, drainage pipes, ballast water pipes, ventilation pipes, etc.8、Seawater Transportation: Seawater desalination plants, coastal power plants, seawater transportation in port cities, submarine pipelines, and optical fiber (cable) conduits.9、Thermal Power Engineering : Process water return transportation, waste slag transportation.10、Highways: Buried water supply and drainage pipes, cable conduits. more>

Company: Nanchang Jinyi Audio-Visual Technology Co., Ltd.
Product Description: How much does the RBX HK-1050 Home Theater Karaoke Sound System cost?The HK Series 2.1/5.1 Home Theater K System is a product designed to resemble traditional bookshelf speakers. Why did we retain the appearance of classic bookshelf speakers? The reason is simple: bookshelf speakers blend more seamlessly with rosewood furniture. Through careful market analysis, we found that some villas lack dedicated home theater or karaoke rooms, forcing homeowners to use the living room as a multipurpose family space. Professional speakers often clash with the interior decor and furniture style in such settings. This is why some homeowners prefer to forgo such speakers rather than compromise their interior design. The HK Series Bookshelf-style Theater K Audio System meets the needs of these customers.How much does the RBX HK-1050 Home Theater Karaoke Sound System cost? more>
