Zeziphi izinto ezisetyenziswayo kwiiNcingo eziRhweba ngamadangatya kunye neeCables?

I-Flame retardant wire, ibhekisela kwi-wire kunye neemeko zokunqanda umlilo, ngokubanzi kwimeko yovavanyo, emva kokuba ucingo lutshiswe, ukuba umbane unqunyulwe, umlilo uya kulawulwa ngaphakathi koluhlu oluthile, awuyi kusasazeka, kunye ne-flame retardant kunye nokuthintela ukusebenza komsi onetyhefu. I-Flame retardant wire njengenxalenye ebalulekileyo yokhuseleko lombane, ukhetho lwemathiriyeli yalo lubalulekile, imarike yangoku isetyenziswa ngokuqhelekileyo i-flame retardant wire materials kuquka.I-PVC, XLPE, irabha ye-silicone kunye nezixhobo zokugquma iiminerali.

I-Flame retardant wire kunye nokukhethwa kwezinto zentambo

Ukuphakama kwesalathiso se-oksijeni yezinto ezisetyenziswe kwikhebula le-flame retardant, ngcono ukusebenza kwe-flame retardant, kodwa ngokunyuka kwesalathisi se-oksijeni, kuyimfuneko ukulahlekelwa ezinye iipropati. Ukuba iipropathi ezibonakalayo kunye nepropathi yenkqubo yezinto ziyancitshiswa, ukusebenza kunzima, kwaye iindleko zezinto zonyuswa, ngoko ke kuyimfuneko ukukhetha ngokufanelekileyo nangokufanelekileyo isalathisi se-oksijini, isalathisi se-oksijini yezinto eziqhelekileyo zokugquma zifikelela kuma-30, imveliso inokudlula kwiimfuno zovavanyo lweklasi C kumgangatho, ukuba i-sheathing kunye nezixhobo zokuzalisa ziyizinto ezinqanda ilangatye, imveliso inokuhlangabezana neemfuno zeKlasi ye-Cable ye-Cable kunye nezixhobo eziphambili ze-Cable. yahlulwe kwizixhobo ze-halogenated flame retardant kunye ne-halogen-free flame retardant materials;

1. Izixhobo ze-halogenated flame retardant

Ngenxa yokubola kunye nokukhululwa kwe-hydrogen halide xa ukutsha kushushu, i-hydrogen halide inokubamba i-root esebenzayo ye-radical HO ingcambu, ukuze ukutshiswa kwezinto kubambezeleke okanye kucinywe ukufezekisa injongo ye-flame retardant. Ngokuqhelekileyo zisetyenziselwa i-polyvinyl chloride, i-rubber ye-neoprene, i-chlorosulfonated polyethylene, i-ethylene-propylene rubber kunye nezinye izinto.

(1) Flame retardant polyvinyl chloride (PVC) : Ngenxa yexabiso eliphantsi le-PVC, ukugquma okulungileyo kunye ne-flame retardant, isetyenziswa ngokubanzi kwintambo eqhelekileyo ye-flame retardant kunye nentambo. Ukuze kuphuculwe i-flame retardancy ye-PVC, i-halogen flame retardants (i-decabromodiphenyl ethers), i-parafini eneklorini kunye ne-synergic flame retardants zihlala zongezwa kwifomula yokuphucula i-flame retardancy ye-PVC.

Irabha ye-ethylene propylene (EPDM) : i-hydrocarbons engeyiyo-polar, eneempawu ezibalaseleyo zombane, ukumelana nokugquma okuphezulu, ilahleko ephantsi ye-dielectric, kodwa irabha ye-ethylene propylene zizinto ezinokutsha, kufuneka sinciphise inqanaba lerabha ye-ethylene propylene enqamlezayo, sinciphise ukuqhawuka kwekhonkco lemolekyuli okubangelwa bubunzima bemolekyuli ephantsi yokuphucula iipropathi ze-flatar;

(2) Umsi ophantsi kunye nezixhobo eziphantsi ze-halogen flame retardant
Ngokukodwa i-polyvinyl chloride kunye ne-chlorosulfonated polyethylene izinto ezimbini. Yongeza i-CaCO3 kunye ne-A (IOH)3 kwifomula ye-PVC. I-Zinc borate kunye ne-MoO3 inokunciphisa ukukhutshwa kwe-HCL kunye nomlinganiselo womsi we-polyvinyl chloride ye-flame retardant, ngaloo ndlela iphucula i-flame retardancy yezinto eziphathekayo, ukunciphisa i-halogen, inkungu ye-asidi, ukukhutshwa komsi, kodwa kunokwenza isalathisi se-oksijini sinciphise kancinci.

2. Izixhobo ze-halogen-free flame retardant

IiPolyolefins zizixhobo ezingenazo ihalogen, eziquka iihydrocarbons eziqhekeza ikharbon diokside kunye namanzi xa zitshisiwe ngaphandle kokuvelisa umsi obalulekileyo kunye neegesi eziyingozi. I-Polyolefin ikakhulu ibandakanya i-polyethylene (PE) kunye ne-ethylene - i-vinyl acetate polymers (E-VA). Ezi zixhobo ngokwazo azinayo i-flame retardant, kufuneka zongeze i-inorganic flame retardants kunye ne-phosphorus series retardants ye-flame retardants, ukuze kuqhutywe kwizinto eziphathekayo ze-halogen-free flame retardant; Nangona kunjalo, ngenxa yokunqongophala kwamaqela e-polar kwitsheyini yemolekyuli yezinto ezingekho phantsi kwe-polar kunye ne-hydrophobicity, ukuxhamla kunye ne-inorganic flame retardants akubi kakhulu, kunzima ukudibanisa ngokuqinileyo. Ukuze kuphuculwe umsebenzi ongaphezulu we-polyolefin, ii-surfactants zingongezwa kwifomula. Okanye kwi-polyolefin exutywe kunye neepolymers eziqulethe amaqela e-polar, ukwenzela ukwandisa inani le-flame retardant filler, ukuphucula iimpawu zomatshini kunye neepropathi zokucubungula izinto, ngelixa ufumana i-flame retardant engcono. Kuya kubonakala ukuba i-flame retardant wire kunye nekhebula isenenzuzo kakhulu, kwaye ukusetyenziswa kuhambelana kakhulu nokusingqongileyo.
