Tlhahlobo ea Melemo ea Ammonium Polyphosphate (APP) joalo ka Sehlahisoa sa mantlha sa Phosphorus-Nitrogen Flame Retardant.

Selelekela

Ammonium polyphosphate (APP) ke e 'ngoe ea tse sebelisoang haholo ho thibela lelakabe la phosphorus-nitrogen (PN) ka lebaka la thepa ea eona e ntle ea ho thibela mollo le ho lumellana le tikoloho. E sebetsa ka ho khetheha lits'ebetsong tse thibelang lelakabe la intumescent, tse sebelisoang ho lipolymer le liphahlo tse fapaneng. Ka tlase ke tlhahlobo ea melemo ea mantlha ea APP joalo ka sesebelisoa sa mantlha sa lelakabe la PN.

1. Tšebeliso e Ntle ea Lelakabe le Phahameng

• Phello ea Synergistic: APP e sebetsa ka tumellano le metsoako e nang le naetrojene ho theha lesela le sireletsang la char nakong ea ho tuka. Lera lena la char le sebetsa e le thibelo ea 'mele, e thibelang mocheso le oksijene hore li se ke tsa fihla linthong tse ka tlaase le ho thibela ho tuka ho eketsehileng.
• Thepa ea Intumescent: Lits'ebetsong tsa intumescent, APP e khothalletsa ho thehoa ha mokelikeli o ruruhileng, o thibelang mocheso o fokotsang haholo ho hasana ha malakabe le ho fokotsa ho lokolloa ha mocheso.

2. Melemo ea Tikoloho le Polokeho

• Chefo e tlase: APP ha e chefo 'me ha e lokolle likhase tse kotsi tsa halogenated (mohlala, dioxin kapa furan) nakong ea ho tuka, e leng se etsang hore e be sebaka se sireletsehileng ho feta li-halogenated flame retardants.
• Eco-Friendly: APP e nkuoa e le botsoalle ho tikoloho hobane ha e bokelle lintho tse phelang 'me e senyeha ho ba lintho tse seng kotsi, tse kang ammonia le phosphoric acid, tlas'a maemo a tloaelehileng.
• Ho Ikamahanya le Melawana: APP e kopana le litlhoko tsa melaoana e meholo ea machaba ea tikoloho, e kang RoHS (Thibelo ea Lintho Tse Kotsi) le REACH (Ngoliso, Tlhahlobo, Tumello, le Thibelo ea Lik'hemik'hale), e etsang hore e tšoanelehe bakeng sa limmaraka tsa lefats'e.

3. Mefuta-futa ea Likopo

• Mefuta e mengata ea li-polymers: APP e sebetsa hantle ho li-polymer tse fapaneng, ho kenyeletsoa polyolefin (mohlala, polyethylene le polypropylene), polyurethanes, epoxy resin, le litlolo. Ho tenyetseha hona ho etsa hore e be khetho e tsebahalang bakeng sa liindasteri tse fapaneng, joalo ka kaho, lisebelisoa tsa elektroniki le masela.
• Ho lumellana le Li-additives tse ling: APP e ka kopanngoa habonolo le li-additives tse ling tse thibelang mollo, joalo ka melamine kapa pentaerythritol, ho ntlafatsa ts'ebetso ea eona ea intumescent system.

4. Khatello ea Mosi le Khase

• Ho Fokotsa Mosi oa Mosi: APP e fokotsa haholo palo ea mosi o hlahisoang nakong ea mollo, e leng ntho ea bohlokoa bakeng sa ho ntlafatsa polokeho ea mollo le ho fokotsa likotsi tsa bophelo bo botle maemong a mollo.
• Ligase tse sa Senyeng: Ho fapana le li-halogenated flame retardants, APP ha e lokolle likhase tse senyang, tse ka senyang lisebelisoa le lisebelisoa nakong ea mollo.

5. Thermal Stability

• Mocheso o Phahameng oa ho Bola: APP e na le botsitso bo botle ba mocheso, 'me mocheso oa ho bola o ka holimo ho 250°C. Sena se etsa hore e loketse lits'ebetso tse hlokang ho hanyetsa mocheso o itekanetseng ho isa ho o phahameng.
• Endothermic Decomposition: Nakong ea ho bola, APP e monya mocheso, o thusang ho pholile thepa le ho liehisa ts'ebetso ea ho tuka.

6. Litšenyehelo-Ka katleho

• Theko e Batlang e Tlase: Ha e bapisoa le li-retardants tse ling tsa malakabe, APP e na le litšenyehelo tse tlaase, haholo-holo ha e sebelisoa lits'ebetsong tsa intumescent moo maemo a tlaase a ho laela a hlokahalang ho finyella katleho e sebetsang ea lelakabe.
• Ts'ebetso ea Nako e telele: Ho tšoarella le botsitso ba APP linthong tse alafiloeng li kenya letsoho ho baballeheng ha eona ka litšenyehelo ho latela nako ea bophelo ea sehlahisoa.

7. Thepa ea Mechini

• Tšusumetso e Nyenyane ho Thepa ea Lintho: Ha e entsoe ka nepo, APP e na le phello e batlang e le tlase mekhoeng ea mochini (mohlala, matla, ho feto-fetoha ha maemo) ea lisebelisoa tse hloekisitsoeng, e etsa hore e lokele lits'ebetso moo ts'ebetso e leng bohlokoa.

Qetello

Ammonium polyphosphate (APP) e hlahella e le ntho e thibelang lelakabe la phosphorus-nitrogen e sebetsang hantle haholo le e baballang tikoloho. Bokhoni ba eona bo phahameng bo thibelang malakabe, chefo e tlase, ho feto-fetoha ha maemo, le ho latela melao ea machabeng ho e etsa khetho e ratoang bakeng sa lits'ebetso tse fapaneng. Ho feta moo, bokhoni ba eona ba ho fokotsa ho ntšoa ha mosi, ho boloka mocheso o tsitsitse, le ho fana ka katleho ea litšenyehelo ho eketsa boipiletso ba eona. Ha liindasteri li ntse li tsoela pele ho etelletsa pele botsitso le polokeho ea mollo, ho ka etsahala hore APP e lule e le karolo ea bohlokoa mefuteng e thibelang mollo. Leha ho le joalo, lipatlisiso tse tsoelang pele le nts'etsopele lia hlokahala ho sebetsana le mefokolo e ka bang teng, joalo ka kutloelo-bohloko ea mongobo, le ho ntlafatsa ts'ebetso ea eona lits'ebetsong tse hlahang.
