Nibihe Bikoresho Byakoreshejwe Muri Flame Retardant insinga ninsinga？

Flame retardant wire, bivuga insinga zifite uburyo bwo kwirinda umuriro, mubisanzwe mugihe cyibizamini, nyuma yo gutwikwa, niba amashanyarazi yahagaritswe, umuriro uzagenzurwa murwego runaka, ntuzakwirakwira, hamwe na retardant kandi ikabuza gukora umwotsi wuburozi. Flame retardant wire nkigice cyingenzi cyumutekano wamashanyarazi, guhitamo ibikoresho byayo ningirakamaro, isoko ryubu rikunze gukoreshwa ibikoresho bya flame retardant wire harimoPVC, XLPE, silicone rubber nibikoresho byo kubika amabuye y'agaciro.

Flame retardant wire hamwe no guhitamo ibikoresho

Iyo urwego rwo hejuru rwa ogisijeni yibikoresho bikoreshwa mu mugozi wa flame retardant, niko imikorere ya retardant ikora neza, ariko hamwe niyongera rya ogisijeni, ni ngombwa gutakaza indi mitungo. Niba ibintu bifatika nibintu bitunganijwe bigabanutse, imikorere iragoye, kandi nigiciro cyibikoresho byiyongereye, bityo rero birakenewe guhitamo muburyo bukwiye kandi bukwiye guhitamo indangagaciro ya ogisijeni, igipimo cya ogisijeni yibikoresho rusange bigera kuri 30, ibicuruzwa birashobora gutsinda ibizamini byicyiciro cya C mubipimo ngenderwaho, niba ibikoresho byo gutwika no kuzuza ibikoresho bigizwe na flame ya retarda hamwe na A. ibikoresho nibikoresho bya halogen bidafite flame retardant;

1. Halogenated flame retardant ibikoresho

Bitewe no kubora no kurekura hydrogène halide mugihe umuriro ushushe, hydrogène halide irashobora gufata umuzi wa radical radical radical yubusa, kugirango gutwika ibintu bitinde cyangwa bizimye kugirango ugere ku ntego yo kuzimya umuriro. Bikunze gukoreshwa ni chloride polyvinyl, reberi ya neoprene, chlorosulfonated polyethylene, reberi ya Ethylene-propylene nibindi bikoresho.

. Mu rwego rwo kunoza urumuri rwa PVC, halogen flame retardants (decabromodiphenyl ethers), paraffine ya chlorine na synergic flame retardants ikunze kongerwaho formula kugirango tunoze umuriro wa PVC.

Rubber ya Ethylene propylene (EPDM): hydrocarbone idafite polar, ifite ibikoresho byiza byamashanyarazi, irwanya insulire nyinshi, igihombo cya dielectric nkeya, ariko reberi ya etylene propylene ni ibikoresho byaka umuriro, tugomba kugabanya urugero rwo guhuza imiyoboro ya etilene propylene reberi, kugabanya imiyoboro ya molekile iterwa nibintu bifite uburemere buke bwa flame;

(2) Umwotsi muke nibikoresho bya halogen flame retardant ibikoresho
Ahanini kuri polyvinyl chloride na chlorosulfonated polyethylene ibikoresho bibiri. Ongeramo CaCO3 na A (IOH) 3 kuri formula ya PVC. Zinc borate na MoO3 birashobora kugabanya irekurwa rya HCL hamwe numwotsi mwinshi wa chloride polyvinyl chloride ya flame retardant, bityo bigatuma flame idasubira inyuma yibikoresho, bikagabanya halogene, igihu cya aside, imyuka y’umwotsi, ariko birashobora gutuma igipimo cya ogisijeni kigabanuka gato.

2. Ibikoresho bya Halogen bidafite umuriro

Polyolefine ni ibikoresho bitarimo halogene, bigizwe na hydrocarbone isenya dioxyde de carbone n'amazi iyo yatwitse idatanga umwotsi mwinshi na gaze zangiza. Polyolefin ikubiyemo polyethylene (PE) na Ethylene - vinyl acetate polymers (E-VA). Ibi bikoresho ubwabyo ntabwo bifite flame retardant, bikeneye kongeramo flame retardants hamwe na fosifore ikurikirana ya flame retardants, kugirango itunganyirizwe mubikoresho bifatika bya halogene bidafite umuriro; Ariko, kubera kubura amatsinda ya polar kumurongo wa molekuline yibintu bidafite polar hamwe na hydrophobicity, isano iri hagati yumuriro utagira ingufu ni muke, biragoye guhuza byimazeyo. Kugirango tunoze ibikorwa byubuso bwa polyolefin, surfactants zirashobora kongerwaho formula. Cyangwa muri polyolefin ivanze na polymers irimo amatsinda ya polar, kugirango wongere umubare wuzuza flame retardant wuzuza, utezimbere imiterere yubukanishi hamwe nuburyo bwo gutunganya ibintu, mugihe ubonye umuriro mwiza. Birashobora kugaragara ko flame retardant wire na kabili biracyari byiza cyane, kandi gukoresha ibidukikije byangiza ibidukikije.
