Tlhahlobo ea Melemo ea Ammonium Polyphosphate (APP) e le Phosphorus-Naetrojene e Sitisang Mollo oa Pele

Selelekela

Ammonium polyphosphate (APP) ke e 'ngoe ea li-retant tsa malakabe tsa phosphorus-nitrogen (PN) tse sebelisoang haholo ka lebaka la thepa ea eona e ntle ea ho thibela malakabe le ho lumellana ha tikoloho. E sebetsa haholo-holo lits'ebetsong tsa ho thibela malakabe tsa intumescent, tse sebelisoang li-polymers le liphahlo tse fapaneng. Ka tlase ke tlhahlobo ea melemo ea bohlokoa ea APP e le se-retant sa malakabe sa PN sa mantlha.

1. Bokgoni bo Phahameng ba ho Sireletsa Mollo

• Phello ea ho Kopanela: APP e sebetsa ka kopanelo le metsoako e nang le naetrojene ho etsa lera la char le sireletsang nakong ea ho cha. Lera lena la char le sebetsa e le tšitiso ea 'mele, le thibela mocheso le oksijene ho fihla thepa e ka tlase le ho thibela ho cha ho eketsehileng.
• Matlotlo a Intumescent: Litsamaisong tsa intumescent, APP e khothalletsa ho thehoa ha lera la char le ruruhileng, le sireletsang mocheso le fokotsang ho ata ha malakabe haholo le ho fokotsa ho lokolloa ha mocheso.

2. Melemo ea Tikoloho le Polokeho

• Chefo e Tlase: APP ha e na chefo 'me ha e ntše likhase tse kotsi tsa halogenated (mohlala, dioxin kapa furans) nakong ea ho cha, e leng se etsang hore e be mokhoa o sireletsehileng oa ho sebelisa li-retant tsa malakabe tsa halogenated.
• E Sireletsa Tikoloho: APP e nkuwa e le mosa tikolohong hobane ha e bokellane 'me e fetoha lintho tse seng kotsi, tse kang ammonia le phosphoric acid, tlas'a maemo a tloaelehileng.
• Ho latela Melaoana: APP e fihlela litlhoko tsa melaoana e meholo ea machaba ea tikoloho, joalo ka RoHS (Thibelo ea Lintho tse Kotsi) le REACH (Ngoliso, Tlhahlobo, Tumello, le Thibelo ea Lik'hemik'hale), e leng se etsang hore e lokele limmaraka tsa lefats'e.

3. Ho Feto-fetoha ha Litšebeliso

• Mefuta e Meholo ea Li-polymer: APP e sebetsa hantle ho di-polymer tse fapaneng, ho kenyeletswa di-polyolefin (mohlala, polyethylene le polypropylene), di-polyurethane, di-resin tsa epoxy, le dikobo. Ho feto-fetoha hona ho etsa hore e be kgetho e tsebahalang bakeng sa diindasteri tse fapaneng, tse kang tsa kaho, tsa elektroniki le tsa masela.
• Ho lumellana le Lisebelisoa tse Ling: APP e ka kopanngoa habonolo le lintho tse ling tse thibelang malakabe, tse kang melamine kapa pentaerythritol, ho ntlafatsa ts'ebetso ea eona lits'ebetsong tsa intumescent.

4. Ho Thibela Mosi le Khase

• Ho Fokotsoa ha Mosi o Ntšoang: APP e fokotsa haholo mosi o hlahisoang nakong ea ho cha, e leng ntho ea bohlokoa bakeng sa ho ntlafatsa polokeho ea mollo le ho fokotsa likotsi tsa bophelo bo botle maemong a mollo.
• Likhase tse sa Senyeheng: Ho fapana le di-halogenated flame retardants, APP ha e lokolle dikhase tse senyang, tse ka senyang disebediswa le meralo ya motheo nakong ya mollo.

5. Ho Tsitsisa ha Thermal

• Mocheso o Phahameng oa ho Bola: APP e na le botsitso bo botle ba mocheso, ka mocheso oa ho bola hangata o fetang 250°C. Sena se etsa hore e lokele lits'ebetso tse hlokang khanyetso e mahareng ho isa ho e phahameng ea mocheso.
• Ho Bola ha Endothermic: Nakong ea ho bola, APP e monya mocheso, e leng se thusang ho pholisa thepa le ho liehisa ts'ebetso ea ho tuka.

6. Ho Sebetsa ka Botlalo Litšenyehelo

• Litšenyehelo tse Tlase Haholo: Ha e bapisoa le lintho tse ling tse thibelang malakabe, APP e theko e tlase, haholo-holo ha e sebelisoa lits'ebetsong tsa intumescent moo maemo a tlase a mojaro a hlokahalang ho fihlela ho thibela malakabe ka katleho.
• Tshebetso ea Nako e Telele: Ho tšoarella le botsitso ba APP thepang e phekotsoeng li tlatsetsa ho bolokeng ha eona litšenyehelo nakong eohle ea bophelo ba sehlahisoa.

7. Thepa ea Mekaniki

• Tšusumetso e Fokolang Matlotlo a Thepa: Ha e hlophisitsoe hantle, APP e na le tšusumetso e tlase haholo litšobotsing tsa mechini (mohlala, matla, ho tenyetseha) tsa thepa e phekotsoeng, e leng se etsang hore e lokele lits'ebetso moo ts'ebetso e leng ea bohlokoa.

Qetello

Ammonium polyphosphate (APP) e hlahella e le sesebelisoa se thibelang malakabe sa phosphorus-naetrojene se sebetsang hantle haholo le se sireletsang tikoloho. Bokgoni ba sona bo phahameng ba ho thibela malakabe, chefo e tlase, ho tenyetseha ha maemo, le ho latela melao ea machaba li etsa hore e be khetho e ratoang bakeng sa mefuta e mengata ea lits'ebetso. Ho feta moo, bokhoni ba sona ba ho fokotsa mosi o tsoang, ho boloka botsitso ba mocheso, le ho fana ka ts'ebeliso e ntle ea litšenyehelo bo eketsa botle ba sona. Ha liindasteri li ntse li tsoela pele ho beha pele botsitso le polokeho ea mollo, APP e kanna ea lula e le karolo ea bohlokoa mefuteng ea ho thibela malakabe. Leha ho le joalo, lipatlisiso le nts'etsopele tse tsoelang pele lia hlokahala ho sebetsana le mefokolo e ka bang teng, joalo ka kutloisiso ea mongobo, le ho ntlafatsa ts'ebetso ea eona lits'ebetsong tse hlahang.
