Ururimi 
Usibye ubwoko buke bwa reberi yubukorikori, byinshi ibikoresho bya rubber , nka reberi , ni gutwikwa cyangwa gutwikwa . Mu nganda nka imbaraga nshya, sisitemu ya batiri , na ibikoresho bya elegitoroniki , flame-retardant ibisabwa bisabwa kubikoresho bya reberi, cyane cyane kubicuruzwa nka Amashanyarazi na Halogen-Yubusa Flame-Retardant Vibration Dampers.
Kugeza ubu, inzira nyamukuru ya tekiniki yo kunoza i flame retardancy of rubber shyiramo:
Ongeraho flame retardants cyangwa flame-retardant yuzuza
Guhindura hamwe nibikoresho bya flame-retardant
Kumenyekanisha flame-retardant amatsinda akora mugihe cya polymerizasiyo
Kongera ubucucike Ibikoresho bya rubber
Ibice bikurikira bitanga ibyiciro bigufi nibisobanuro bya rubber flame-retardant tekinoroji.
1. Ikoreshwa rya Flame-Retardant Technologies ya Hydrocarubone
1.1 Ibiranga amabuye ya hydrocarubone
Rubber harimo:
NR (Rubber Kamere)
SBR (Styrene-Butadiene Rubber)
BR (Butadiene Rubber)
IIR (Butyl Rubber)
EPR / EPDM (Rubanda ya Ethylene Propylene)
Nubwo NBR (Nitrile Rubber) ntabwo isanzwe ya hydrocarubone reberi, yayo uburyo bwo kuvura flame-retardant birasa kandi mubisanzwe biganirwaho hamwe mubikorwa bya injeniyeri.
Ibintu nyamukuru biranga amabuye ya hydrocarubone arimo:
Kugabanya Oxygene Yerekana (LOI): hafi. 19–21
Ubushyuhe bwo kubora: 200-500 ° C.
Kurinda umuriro nabi no kurwanya ubushyuhe
Igisekuru kinini imyuka yaka umuriro mugihe cyo gutwikwa
Kubwibyo, iyo bikoreshejwe Amashanyarazi, inganda zangiza , cyangwa rusange muri vibration kwigunga , flame-retardant guhindura ni ngombwa.
1.2 Uburyo busanzwe bwa Flame-Retardant Uburyo bwa Hydrocarubone
(1) Kuvanga na Flame-Retardant Polymers
Muguhuza hydrocarbon reberi na flame-retardant polymers nka:
Polyvinyl Chloride (PVC)
Chlorine Polyethylene (CPE)
Chlorosulfonated Polyethylene (CSM)
Ethylene-Vinyl Acetate (EVA)
gucana umuriro birashobora kunozwa kurwego runaka. Mugihe cyo kuvanga, hagomba kwitabwaho byumwihariko:
Guhuza ibikoresho
Igishushanyo mbonera cya sisitemu
Ubu buryo bukoreshwa cyane Ibikoresho bya Batiri cyangwa ibice bitari hejuru-byoroshye.
(2) Kwiyongera kwa Flame Retardants (Uburyo bwibanze)
Inyongera ya flame retardants nuburyo bwingenzi cyane bwo kongera ububobere bwa flame muri rebero ya hydrocarubone kandi birashobora kurushaho kunozwa binyuze sisitemu yo guhuza ibikorwa.
Organic halogen ishingiye kuri flame retardants (ibisubizo gakondo):
Ibikomoka kuri Hexachlorocyclopentadiene
Decabromodiphenyl ether
Chorine paraffin
Inorganic synergistic flame retardants:
Antimony trioxide (Sb₂O₃) (bikunze gukoreshwa)
Zinc borate
Hydroxide ya aluminium
Amonium chloride
⚠ Ingingo z'ingenzi:
Halogen-ishingiye kumuriro ntigomba kubamo kubuntu , bitabaye ibyo barashobora:
Kora ibikoresho byo gutunganya no kubumba
Mugabanye imikorere yamashanyarazi
Ingaruka mbi zo kurwanya gusaza
Muri imbaraga nshya na inganda za elegitoroniki, Halogen-Yubusa Flame-Retardant Vibration Dampers babaye inzira nyamukuru, biganisha ku guhitamo gukomeye kuri sisitemu ya halogen-flame-retardant sisitemu.
(3) Kwiyongera kwa Flame-Retardant Inorganic Fillers
Bikunze gukoreshwa byuzuza birimo:
Kalisiyumu karubone
Ibumba rya Kaolin
Talc
Silica
Hydroxide ya aluminium
Ubu buryo butezimbere umuriro:
Kugabanya igipimo cya ibicanwa bishobora gutwikwa
Gukoresha ingaruka zo kubora Bya
Kurugero:
Kalisiyumu karubone na hydroxide ya aluminium gukuramo ubushyuhe bukomeye mugihe cyo kubora
Ariko, hagomba kwitonderwa ko ibyo:
Kwuzuza birenze urugero kugabanuka biragabanuka Ibikoresho bya mashini
Ntibikwiriye hejuru-byoroshye cyangwa ibice byinshi byo kunyeganyega
(4) Kongera Ubucucike bwa Rubber
Ubushakashatsi bwerekanye ko:
Ubucucike buri hejuru → Indangagaciro ya ogisijeni → Kunanirwa kwaka umuriro
Ubu buryo bushobora kuba bufitanye isano na kwiyongera k'ubushyuhe bwo kubora.
Ubu buryo bwakoreshejwe neza Sisitemu ya EPDM kandi birakwiriye:
Amashanyarazi akoreshwa mubushyuhe bwo hagati-hejuru-hejuru
Flame-flame-retardant vibration igabanya ibice bya reberi
2. Flame-Retardant Ibiranga Halogenated Rubber
Rubber muburyo busanzwe burimo ibintu bya halogene kandi mubisanzwe birerekana:
Icyerekezo cya Oxygene: 28-45
Indangantego ya ogisijeni ya FPM (Fluororubber) irenga 65
Ibirimo byinshi bya halogene → flame retardancy
Imyitwarire yo kwizimya nyuma yo gukuraho flame
Ingaruka zabyo, kuvura flame-retardant ya halogenated reberi biroroshye cyane, akenshi bisaba imbaraga nkeya gusa hamwe na retardants.
⚠ Ariko, kubera amabwiriza y’ibidukikije (nka RoHS na SHAKA ) n'ibigenda muri inganda nshya, halogen-ibisubizo bagenda batoneshwa. Ninimpamvu yingenzi yo kwakirwa kwinshi Halogen-Yubusa Flame-Retardant Vibration Dampers.
3. Flame-Retardant Technologies ya Heterochain Rubbers
Abahagarariye cyane rubberber ni:
Dimethyl Silicone Rubber (VMQ)
Ibintu byingenzi biranga harimo:
Indwara ya Oxygene igera kuri 25
Ubushyuhe bwo kubora bugera kuri 400-600 ° C.
Ubwiza buhebuje bwo hejuru
Flame-retardant uburyo bwa silicone reberi irimo:
Kwiyongera ubushyuhe bwo kubora
Kongera umubare wa char isigaye nyuma yo kubora
Kugabanya igipimo cyibisekuru bya gaze yaka
Nkigisubizo, rubber ni Byakoreshejwe Muri:
Ubushyuhe bwo hejuru
Hejuru-ya halogen-yubusa flame-retardant ibice byo kumena
Ibikoresho birinda ibikoresho bya elegitoroniki nibikoresho bishya byingufu
Umwanzuro
Igishushanyo cya flame-retardant ya rubber bigomba gusuzumwa byuzuye bishingiye Ubwoko bwa rubber, Porogaramu Ibidukikije , na ibisabwa n'amategeko.
Kuri Porogaramu nka:
Amashanyarazi
Halogen-Yubusa Flame-Retardant Vibration Dampers
birasabwa gushyira imbere:
Sisitemu ya Halogen idafite flame-retardant
Igishushanyo mbonera gikwiye
Kuringaniza ibisubizo hagati ya flame-retardant yuzuza nibikorwa bya mashini
Usibye ubwoko buke bwa reberi yubukorikori, byinshi ibikoresho bya rubber , nka reberi , ni gutwikwa cyangwa gutwikwa.
