Kev soj ntsuam ntawm qhov zoo ntawm Ammonium Polyphosphate (APP) raws li Thawj Phosphorus-Nitrogen Flame Retardant

Taw qhia

Ammonium polyphosphate (APP) yog ib qho ntawm feem ntau siv phosphorus-nitrogen (PN) nplaim retardants vim nws zoo heev nplaim-retardant zog thiab ib puag ncig compatibility. Nws yog tshwj xeeb tshaj yog zoo nyob rau hauv intumescent nplaim-retardant systems, uas yog siv nyob rau hauv ntau yam polymers thiab coatings. Hauv qab no yog ib qho kev ntsuam xyuas ntawm qhov zoo ntawm APP raws li thawj PN nplaim taws retardant.

1. High nplaim taws retardant efficiency

• Synergistic nyhuv: APP ua haujlwm sib koom ua ke nrog cov khoom sib txuas nrog nitrogen los tsim cov txheej txheem tiv thaiv char thaum lub sij hawm combustion. Cov txheej char no ua raws li lub cev thaiv kev tiv thaiv, tiv thaiv tshav kub thiab oxygen kom ncav cuag cov khoom siv hauv qab thiab inhibiting combustion ntxiv.
• Intumescent Properties: Nyob rau hauv intumescent systems, APP txhawb kev tsim ntawm o, insulating char txheej uas ua rau kom qeeb ntawm cov nplaim taws thiab txo cov cua sov.

2. Cov txiaj ntsig ntawm ib puag ncig thiab kev nyab xeeb

• Tsawg toxicity: APP tsis muaj tshuaj lom thiab tsis tso cov pa phem halogenated (piv txwv li, dioxins lossis furans) thaum lub sij hawm combustion, ua rau nws muaj kev nyab xeeb dua rau cov nplaim hluav taws halogenated.
• Eco-Friendly: APP yog suav tias yog ib puag ncig tus phooj ywg vim nws tsis bioaccumulate thiab tawg mus rau hauv cov khoom tsis muaj kev phom sij, xws li ammonia thiab phosphoric acid, nyob rau hauv ib txwm muaj.
• Ua raws li Txoj Cai: APP ua tau raws li qhov yuav tsum tau muaj ntawm cov kev cai loj thoob ntiaj teb ib puag ncig, xws li RoHS (Tshwj xeeb ntawm cov khoom phom sij) thiab REACH (Kev Sau Npe, Kev Ntsuas, Kev Tso Cai, thiab Kev Txwv Cov Tshuaj), ua rau nws tsim nyog rau kev lag luam thoob ntiaj teb.

3. Versatility nyob rau hauv daim ntawv thov

• Ntau yam ntawm Polymers: APP siv tau rau ntau yam polymers, suav nrog polyolefins (piv txwv li, polyethylene thiab polypropylene), polyurethanes, epoxy resins, thiab coatings. Qhov kev ua tau zoo no ua rau nws muaj kev xaiv nrov rau ntau hom kev lag luam, xws li kev tsim kho, hluav taws xob, thiab textiles.
• Compatibility nrog lwm yam additives: APP tuaj yeem yooj yim ua ke nrog lwm cov nplaim hluav taws xob ntxiv, xws li melamine lossis pentaerythritol, txhawm rau txhim kho nws cov kev ua tau zoo hauv cov kab mob intumescent.

4. Kev haus luam yeeb thiab roj

• Txo cov pa luam yeeb: APP txo qis cov pa luam yeeb uas tsim thaum lub sij hawm combustion, uas yog ib qho tseem ceeb rau kev txhim kho hluav taws kev nyab xeeb thiab txo cov kev pheej hmoo ntawm kev noj qab haus huv nyob rau hauv cov xwm txheej hluav taws.
• Tsis-Corrosive Gases: Tsis zoo li cov nplaim hluav taws halogenated, APP tsis tso cov roj corrosive, uas tuaj yeem ua rau cov khoom siv thiab cov khoom siv puas tsuaj thaum muaj hluav taws kub.

5. Thermal stability

• High Decomposition Kub: APP muaj qhov zoo thermal stability, nrog rau qhov decomposition kub feem ntau siab dua 250 ° C. Qhov no ua rau nws haum rau cov ntawv thov uas xav tau nruab nrab mus rau siab thermal kuj.
• Endothermic decomposition: Thaum lub sij hawm decomposition, APP absorbs cua sov, uas yuav pab kom txias cov khoom thiab ua rau kom cov txheej txheem combustion qeeb.

6. Nqi-zoo

• Tus nqi qis: Muab piv rau lwm cov nplaim hluav taws, APP yog tus nqi tsim nyog, tshwj xeeb tshaj yog thaum siv hauv cov tshuab intumescent uas yuav tsum muaj cov khoom qis qis kom ua tiav cov nplaim hluav taws xob zoo.
• Kev Ua Haujlwm Ntev: Lub durability thiab stability ntawm APP nyob rau hauv cov ntaub ntawv kho mob pab txhawb rau nws cov nqi-zoo tshaj lub lifecycle ntawm cov khoom.

7. Mechanical Properties

• Kev cuam tshuam tsawg kawg nkaus rau cov khoom vaj khoom tsev: Thaum tsim tau zoo, APP muaj qhov cuam tshuam tsis zoo rau cov khoom siv kho tshuab (xws li, lub zog, kev hloov pauv) ntawm cov ntaub ntawv kho, ua rau nws tsim nyog rau cov ntawv thov uas qhov kev ua haujlwm tseem ceeb.

Xaus

Ammonium polyphosphate (APP) sawv tawm raws li qhov ua tau zoo thiab ib puag ncig tus phooj ywg phosphorus-nitrogen nplaim taws retardant. Nws cov nplaim hluav taws kub-retardant efficiency, tsis tshua muaj toxicity, versatility, thiab ua raws li cov kev cai thoob ntiaj teb ua rau nws nyiam xaiv rau ntau yam kev siv. Tsis tas li ntawd, nws lub peev xwm los txo cov pa luam yeeb, tswj cov thermal stability, thiab muab cov nqi-zoo ntxiv txhim kho nws qhov kev thov. Raws li kev lag luam txuas ntxiv tseem ceeb rau kev ruaj khov thiab kev nyab xeeb hluav taws, APP zoo li yuav nyob twj ywm tseem ceeb hauv cov qauv hluav taws xob. Txawm li cas los xij, kev tshawb fawb tsis tu ncua thiab kev txhim kho yog tsim nyog los daws cov kev txwv muaj peev xwm, xws li ya raws rhiab heev, thiab txhawm rau txhim kho nws cov kev ua tau zoo hauv cov ntawv thov tshiab.
