Izinzuzo kanye Nobubi be-Inorganic Flame Retardants

Ukusetshenziswa okubanzi kwezinto ze-polymer kusheshise ukukhula kwemboni ye-flame retardant. Ama-flame retardants ayisigaba esibaluleke kakhulu sezithasiselo ezibonakalayo emphakathini wanamuhla, avimbela ngokuphumelelayo imililo, alawule ukusabalala kwawo, futhi anikele ngokuphawulekayo ekuphepheni kokukhiqiza kanye nempilo yansuku zonke. Izinto ezilashwa ngezinqamuli zomlilo zingavimbela ngempumelelo, zingasheshi, noma zimise ukubhebhetheka kwamalangabi lapho zivezwe emithonjeni yomlilo yangaphandle, ngaleyo ndlela kuzuze imiphumela yokunqanda ilangabi. Kunezinhlobo eziningi zamalangabi, futhi yonke into inezinhlangothi ezimbili—ama-flame retardants nawo anobuhle nobubi bazo. Ngezansi ukuhlaziya okuhle nokubi kwezinhlobonhlobo ze-inorganic flame retardants.

Ububi be-Inorganic Flame Retardants:
Umphumela oyinhloko wama-inorganic flame retardants umthamo wawo ophezulu odingekayo (ikakhulukazi ongaphezu kuka-50%) ezintweni ze-polymer, ezingakhinyabeza kalula ukusebenza kokucubungula kanye nezakhiwo zomzimba. Izixazululo zihlanganisa ukwelashwa okungaphezulu ngama-ejenti ahlanganisayo, ukucolisiswa kwezinhlayiyana ze-ultrafine, kanye ne-nanotechnology, emele inkomba ebalulekile yentuthuko yesikhathi esizayo.

Izinzuzo zama-Inorganic Flame Retardants:

1. I-Aluminium Hydroxide (ATH): Ihlanganisa ukubambezeleka komlilo, ukucindezela intuthu, nemisebenzi yokugcwalisa ibe yinto eyodwa. Ayinabuthi, ayigqwali, izinzile kakhulu, ayikhiqizi amagesi anobuthi emazingeni okushisa aphezulu, ayibizi kakhulu, futhi itholakala kabanzi.
2. I-Magnesium Hydroxide (MTH): Ibola phakathi kuka-340–490°C, ihlinzeka ngokuzinza okuhle kakhulu kokushisa kanye nokuncipha komlilo okuvelele kanye nemiphumela yokucindezela intuthu. Ifaneleka ikakhulukazi ukucubungula amapulasitiki e-polyolefin emazingeni okushisa aphezulu.
3. I-Phosphorus Ebomvu: Ihlinzeka ngokucindezelwa kwentuthu, ubuthi obuphansi, kanye nokunqanda ilangabi elisebenza kahle kakhulu. Kodwa-ke, i-phosphorus ebomvu ithambekele ekungeneni kwe-oxidation emoyeni, ingase izishise ngokuzenzakalelayo, futhi kancane kancane ikhiphe igesi ye-phosphine enobuthi ekugcinweni kwesikhathi eside. Ukuhambisana kwayo nezinto ze-polymer kubi, kanti i-microencapsulation iyisixazululo esiyinhloko.
4. I-Ammonium Polyphosphate (APP): Futhi i-intumescent retardant, iqukethe amazinga aphezulu e-nitrogen ne-phosphorus, ibonisa ukuzinza okuhle kwe-thermal, futhi ayithathi hlangothi ekwakhekeni. Ingaxutshwa nezinye izinqamuleli zomlilo, inikeza ukuhlakazeka okuhle, futhi inobuthi obuphansi, iqinisekisa ukusetshenziswa okuphephile. Kodwa-ke, uma idigri ye-polymerization ye-APP yehla, iba nokuncibilika emanzini. Ukwengeza, i-APP ine-acidic kancane futhi ijwayele ukumuncwa umswakama ezindaweni ezinomswakama.
