Isingeniso Flame retardants

I-Inorganic Flame RetadadantsIsebenza ngokomzimba, okusebenzayo okuphansi kanye nenani elikhulu lesengezo. Inomthelela othile ekusebenzeni kwezinto zokwakha. Kodwa-ke, ngenxa yentengo ephansi ingasetshenziswa emikhiqizweni ephansi ephansi enezidingo eziphansi zokusebenza, njengePlastics PE, PVC, njll. Thatha i-aluminium hydroxide (ath) njengesibonelo Inqubo yokubola ibamba ukushisa nokushibilika kwamanzi, ukuze ivimbela ukukhuphuka kwezinga lokushisa kwezinto ezibonakalayo, yehlisa izinga lokushisa lendawo ebonakalayo, yehlise ijubane lejubane lokuphendula okuqhekekayo okushisayo. Ngasikhathi sinye, umphunga wamanzi angaphonsa i-oksijini yokuhlushwa futhi avikele ukuhlanganiswa kwe-oxygen futhi avikele ukuhlanganiswa kwe-

I-Organic Halogen Flame retadadantsKakhulu yamukela indlela yamakhemikhali. Ukusebenza kwayo kuphakeme futhi ukwengeza kunguSamll ngokuhambisana okuhle nama-polymers. Zisetshenziswa kabanzi ezindaweni ezisetshenziselwa ama-elekthronikhi, amabhodi wesifunda aphrintiwe nezinye izinto zikagesi. Kodwa-ke, bazokhipha amagesi anobuthi futhi awonakalisayo, anezinkinga ezithile zokuphepha nezemvelo.I-Bromalited Flame Retadadants (BFRS)ikakhulukazi zinomusa amalangabi amalangabi amalangabi. EnyeI-Chloro-Series Fire Retardants (CFRS). Ukushisa kwabo kokubola kuyafana nalokho kwezinto ze-polymer. Lapho ama-polmers efudumele futhi ebolile, ama-BFRs aqala ukubola, faka indawo yokuvungulwa kwegesi yegesi kanye nemikhiqizo yokubola kwe-thermal, vimbela ukusabela nokuvimbela ukusakazwa kwelangabi. Ngasikhathi sinye, igesi ekhishwe ihlanganisa ingaphezulu lezinto ezibonakalayo ukuze ivimbe futhi ithele okuhlushwa umoya-mpilo, bese ekugcineni yehlisa ukusabela kwe-combustion kuze kube kunqanyulwe. Ngaphezu kwalokho, ama-BFR avame ukusetshenziswa ngokuhlanganiswa ne-antimony oxide (ato). I-ato ngokwayo ayinayo i-flame retardancy, kepha ingasebenza njenge-catalyst ukusheshisa ukubola kwe-bromine noma i-chlorine.

I-Organic phosphorus flame retardants (OPFRS)Isebenza ngokomzimba nangokomzimba nangomakhemikhali, ngokusebenza okuphezulu kanye nezinzuzo zobuthi obuphansi, ukuqina kanye nokusebenza kwezindleko eziphakeme. Ngaphezu kwalokho, futhi kungathuthukisa ukucubungula uketshezi lwe-alloy, kunikeze umsebenzi wepulasitiki kanye nokusebenza okuhle kakhulu.

Yize ukwengeza uFr kungeke kwenze lokho okushiwo ngumlilo ngokugcwele, kungakugwema ngempumelelo i- "Flash Burn Burn" Penomenon, yehlisa ukuvela komlilo futhi uzuze isikhathi esibalulekile sokubaleka kubantu abasendaweni yomlilo. Ukuqiniswa kwezidingo zikazwelonke ze-Flame Retardant Technology futhi kwenza ithemba lokuthuthuka kwama-frs abanzi kakhulu.
