Ilaphu liyayikhaba ifayibha yangaphambili ene-oxidized ukumelana nobushushu obuphezulu kunye ne-aramid enamandla amakhulu aphezulu, ukungunda okuphezulu, ukumelana nobushushu obuphezulu kunye nokumelana nokunxiba, okudityaniswe ngokomlinganiselo othile. Ukoyisa ukungalungi kwezi micu mibini. Iinzuzo zazo zombini iintsinga ziyaziswa.
Ibanga elibuyisela idangatye: Ubunzima besi salathisi kukujikeleza kwesilika esele ine-oxygen kunye ne-aramid. Izinto ezinqanda amadangatye kwimpahla yokunxiba abenzi belaphu elingatshiyo emva kokuphunyezwa kokungaphezulu, uqwalaselo kunye netekhnoloji iye yatshintshwa kakhulu, ukuze izinga lokujikeleza kunye nomgangatho womsonto uphuculwe kakhulu, ukujikeleza.umzi-mveliso wephepha we-aramidizinga lifikelele ngaphezu kwama-80%. Emva kovavanyo lombutho omkhulu wamandla, izalathi zelaphu zifikelele kwiimfuno ezisemgangathweni ezifanelekileyo, zinokwenziwa ngobushushu obuphezulu obunganyangekiyo, ukugqunywa kobushushu, impahla ekhuselayo yomlilo. Ilaphu alinawo amandla abalaseleyo, ukuxhathisa ukunxiba, kunye nelangatye eligqwesileyo, ukumelana nobushushu obuphezulu, ukuxhathisa kwimitha ye-thermal, ukuba nje ixabiso lokungenisa uhlobo olufanayo lwe-1113, kukho amathuba amahle kakhulu okusebenza. Eli laphu lingqinwe ngabasebenzisi ukuba lilawule ngokwenyani, kwindawo yelaphu lokhuselo lwe-UV, imitha yobushushu obuphezulu, amathontsi aphezulu anyibilikayo, amadangatye avuthayo njalo njalo. Ilaphu linokuxhathisa ubushushu obuphezulu, ukugqunywa kobushushu, idangatye elibuyiswayo elisebenza ngelaphu elihlanganisiweyo lilungile, amandla aphezulu kunye namandla olawulo olusisigxina ayancipha kancinci.umzi-mveliso wephepha we-aramid
2 Isetyenziswa ngokuqhelekileyo idangatye retardant kunye nelaphu retardant encedisayo ulwahlulo: iintlobo ngeentlobo retardant ilangatye, iindlela zohlelo nazo ezahlukeneyo. Ngokutsho izinto idangatye retardant, inokohlulwa ibe halogenated idangatye retardant, phosphorus idangatye retardant, nitrogen idangatye retardant, njl Ngokutsho ukusetyenziswa idangatye retardant kunye polymer kwifom, yahlulwe yongeza uhlobo kunye nohlobo reaction; Ngokokomelela kwelaphu elibuyiswa ngamadangatya, linokwahlulwa libe ziindidi ezintathu: i-arhente yokugqiba i-retardant engagungqiyo, i-ejenti yokugqiba idangatye ehlala ixesha elide kunye ne-ejenti yokugqiba i-flame retardant. Ngokohlobo lwekhompawundi inokwahlulwa ibe yi-inorganic flame retardant kunye ne-organic flame retardant. Oku kulandelayo kwazisa ngokuyintloko iingubo zokusebenza ze-flame retardant ezihlelwe ngeendlela ezimbini zokugqibela.
1.1 Ukuhlelwa ngokomelela kwamalaphuumzi-mveliso wephepha we-aramid
I-1) i-ejenti yokugqiba i-flame retardant engapheliyo: eyaziwa ngokuba yi-arhente yokugqiba i-flame retardant, uninzi lwazo luyi-soluble yamanzi (okanye i-emulsion) ye-inorganic salts. I-flame retardant inyibilika emanzini, kwaye ilaphu lingasetyenziswa emva kokudipha kunye nokomisa. Kukho kwakhona ukuhlamba kabini, ibhafu yesibini kunye ne-ammonia okanye i-soda ash, ukwenzela ukuba i-oxide ifakwe kwilaphu. Le ndlela ilula kwaye inexabiso eliphantsi, kodwa imvakalelo yelaphu ihlwempuzekile, kwaye isiphumo sokubuyiswa komlilo siyancipha kakhulu emva kokuhlamba. Ihlala isetyenziswa kwimpahla yokukhusela elahlayo.
(2) i-ejenti yokugqiba i-retardant ye-flame retardant: amalaphu angaguquguqukiyo anyangwa ngale nkqubo anokuhlanjwa ngobunono kangange-1 ~ 10 amaxesha, kodwa angaxhathisi kubushushu obuphezulu bokuhlamba isepha. Indlela iquka indlela ye-urea phosphoric acid (edla ngokuba yi-Banflam indlela), indlela ye-phosphate yomchamo, i-ammonium phosphate - i-methyl acetate isisombululo esixubileyo.
(3) I-arhente yokugqiba i-flame-retardant yokugqibezela: Indlela yekhemikhali isetyenziselwa i-polymerization okanye ukudibanisa kwindawo yangaphakathi ye-fiber ukwenza i-polymer enganyibilikiyo yamanzi, kwaye ukuxhathisa ukuhlamba ngokuqhelekileyo kufuneka kube ngaphezu kwamaxesha angama-30. Iindlela eziphambili ziquka indlela yeCiba (CP) kunye nendlela yeProban. Inkqubo ye-CP yenziwe yiNkampani yeCiba, eSwitzerland. Inkqubo kulula ukuyiphumeza kwaye umphumo we-flame-retardant uyamangalisa. Ukungalungi kukuba ukulahlekelwa kwamandla kwengubo kukhulu kwaye impembelelo ekusebenzeni kwengubo inkulu. Indlela yeProban yadalwa yi-British Aubry Wilson Co., LTD., Le ndlela igqityiwe ilaphu, i-flame retardant effect ilungile, ngakumbi emva kokuba unyango lwelaphu luziva kunye nokugcinwa okunamandla alunakuthelekiswa nayo nayiphi na enye indlela yokugqiba, kodwa le ndlela iyingozi ngakumbi, ungcoliseko olunzulu lokusingqongileyo, ngoko ke ukukhuthazwa kulinganiselwe.
2.2 Ukuhlelwa kweeretardants zomlilo ngokohlobo oluxutywe
(1) i-inorganic flame retardant: I-Inorganic flame retardant yeyona ndima iphambili yokufunxa ubushushu, ezona ntlobo ziphambili zine-antibacterial deodorant ilaphu i-aluminium hydroxide, i-magnesium hydroxide, i-phosphorus ebomvu, i-antimony oxide, i-molybdenum oxide, i-ammonia molybdate, i-zinc borate, i-zinc oxide, i-zirconia. , zirconia, zirconia, njl, kunye ne-aluminium i-hydroxide, i-magnesium hydroxide, i-phosphorus ebomvu, i-antimony oxide yeyona nto isetyenziswa kakhulu, ngakumbi i-aluminium hydroxide, i-magnesium hydroxide ayinakudlala kuphela impembelelo yomlilo, kodwa inokudlala Ukuzalisa isenzo. Baneempawu zokuzinza okuhle kwe-thermal, ukusebenza okuphezulu, ukunyanzeliswa komsi, ukuxhathisa ukuvuza, ukuzaliswa ngokukhuselekileyo, ngokusisiseko akukho ngcoliseko lokusingqongileyo kunye nexabiso eliphantsi, njl. Kodwa ukunganyangeki kwelaphu elingaguquguqukiyo kwilangatye lokungaguquki kulunga, oku kungenxa yokuba i-inorganic flame retardant ine-polarity eyomeleleyo kunye ne-hydrophilicity, kwaye ukuhambelana kwelaphu le-non-polar kubi. Kwangaxeshanye, ukuze kuhlangatyezwane neemfuno ezimiselweyo ze-flame retardant, i-inorganic flame retardants yongezwa kwixabiso elikhulu, elinempembelelo enkulu kwiipropathi zoomatshini kunye neepropathi zokucubungula izinto. Ke ngoko, kwiminyaka yakutshanje, uphando malunga nokucokiseka okuphezulu kunye nokwenziwa kwezixhobo zendalo ezibuyisela amadangatye endalo zifumene ingqalelo engazange ibonwe ngaphambili. Ukongeza, ukuze kuncitshiswe inani le-flame retardant kunye nesiphumo esifanayo sokubuyiswa komlilo, ikwayisikhokelo sophando se-flame retardant kwiminyaka yakutshanje ukudibanisa i-flame retardant kunye nokufunda i-synergistic effect ye-flame retardant.
(2) i-organic flame retardants: i-organic flame retardants yahlulwe ibe yi-phosphorus series kunye ne-halogen series. Eyangaphambili ilinganiselwe kakhulu ekusebenziseni kwayo. IHalogenated flame retardants ikakhulu ibandakanya iklorine kunye nebromine. Nangona kunjalo, impembelelo ye-chlorine flame retardants imbi kakhulu kune-bromine flame retardants, kuba akulula ukuvelisa iqela le-chlorine yamahhala. Ilaphu elichasene nemibimbi kunye ne-non-ironing, ukongeza, ngenxa yokubola kunye netyhefu ye-bromide emva kokubola kwe-thermal kuncinci, ngoko ke usetyenziso oluncinci lunokufikelela kwisiphumo esifanayo somlilo ovuthayo njenge-chloride. Ke i-brominated flame retardants ixhaphake kakhulu. Nangona kunjalo, ngokwembono yokusetyenziswa ngokubanzi, ngenxa yeentsilelo ze-halogenated flame retardants, eziqulethe i-asidi ye-halogenated kwiimveliso zabo zokubola, umsi omkhulu kunye nobungozi kumzimba womntu, zitshintshwa ngokuthe ngcembe zezinye i-inorganic flame retardant kunye nelaphu elingatshiyo. izongezo.
