Sai dai wasu nau'ikan roba na roba, galibi roba roba kayayyakin , kamar roba na halitta , su ne abubuwa masu ƙonewa ko masu ƙonewa . A cikin masana'antu irin su sabon makamashi, tsarin baturi , kuma kayan lantarki , Ana sanya buƙatun masu kare wuta mafi girma akan abubuwan roba, musamman ga samfuran kamar Kayan Batir kuma Halogen-Free Flame-Retardant Vibration Dampers.
A halin yanzu, manyan hanyoyin fasaha don ingantawa harshen wuta na kayayyakin roba hada da:
Ƙara harshen wuta ko masu kashe wuta
Gyaran haɗawa tare da kayan kare wuta
Gabatarwa ƙungiyoyin ayyuka masu hana harshen wuta a lokacin polymerization
Ƙara da crosslink yawa na kayayyakin roba
Bangarorin da ke gaba suna ba da taƙaitaccen rarrabuwa da bayanin fasahohin hana harshen wuta na roba.
1. Fasaha-Retardant Fasaha don Hydrocarbon Rubbers
1.1 Halayen Rubbers na Hydrocarbon
Hydrocarbon rubbers yafi hada da:
NR (Rubber Na halitta)
SBR (Styrene-Butadiene Rubber)
BR (Butadiene Rubber)
IIR (Butyl Rubber)
EPR / EPDM (Ethylene Propylene Rubber)
Ko da yake Nitrile Rubber (NBR) ba na roba hydrocarbon roba, da hanyoyin magance harshen wuta suna kama da kuma yawanci ana tattaunawa tare a aikace-aikacen injiniya.
Babban halayen rubbers na hydrocarbon sun haɗa da:
Ƙimar Oxygen Index (LOI): kimanin. 19-21
Zazzabi mai zafi: 200-500 ° C
Rashin jinkirin harshen wuta da juriya mai zafi
Generation na babban adadin iskar gas masu ƙonewa yayin konewa
Don haka, lokacin da aka yi amfani da shi a ciki Kayan Batir, masana'antu damping gammaye , ko abubuwan keɓancewar jijjiga gabaɗaya , gyaggyarawa mai kashe wuta yana da mahimmanci.
1.2 Hanyoyi na gama-gari na ƙoshin wuta don Rubbers na Hydrocarbon
(1) Haɗuwa tare da Polymers masu hana wuta
Ta hanyar haɗa rubbers na hydrocarbon tare da polymers masu kare wuta irin su:
Polyvinyl Chloride (PVC)
Polyethylene Chlorinated (CPE)
Chlorosulfonated Polyethylene (CSM)
Ethylene-Vinyl Acetate (EVA)
za a iya inganta jinkirin harshen wuta zuwa wani matsayi. A lokacin haɗuwa, dole ne a biya kulawa ta musamman:
Dacewar kayan aiki
Tsarin tsarin haɗin gwiwar haɗin gwiwa
Ana yawan amfani da wannan hanyar don Pads Batirin tsarin ko abubuwan damping da ba high-elasticity.
(2) Ƙarin Ƙarfafa Harshen Wuta (Tsarin Farko)
Bugu da kari na harshen wuta ita ce hanya mafi mahimmanci don haɓaka jinkirin harshen wuta a cikin robar hydrocarbon kuma ana iya ƙara inganta ta ta hanyar. tsarin synergistic.
Dabbobin harshen wuta na tushen halogen (maganin gargajiya):
Abubuwan Hexachlorocyclopentadiene
Decabromodiphenyl ether
Chlorinated paraffin
Inorganic synergistic harshen wuta retardants:
Antimony trioxide (Sb₂O₃) (yawanci amfani)
Zinc borate
Aluminum hydroxide
Ammonium chloride
⚠ Muhimman Bayanan kula:
Dole ne kada ya ƙunshi tushen harshen harshen halogen free halogens , in ba haka ba za su iya:
Lalata kayan aiki da kyawon tsayuwa
Rage aikin rufin lantarki
Rashin tasiri yana shafar juriyar tsufa
A cikin sabon makamashi kuma masana'antun lantarki, Halogen-Free Flame-Retardant Vibration Dampers sun zama al'ada, yana haifar da fifiko mai ƙarfi don tsarin hana wuta-free halogen.
(3) Ƙarin Abubuwan Ciki na Inorganic
Filayen da aka fi amfani da su sun haɗa da:
Calcium carbonate
Kaolin yumbu
Talc
Silica mai hazo
Aluminum hydroxide
Wannan hanya tana inganta jinkirin wuta ta:
Rage rabo daga konewa kwayoyin abu
Amfani da endothermic bazuwar sakamako na fillers
Misali:
Calcium carbonate kuma aluminum hydroxide sha gagarumin zafi a lokacin bazuwar
Duk da haka, dole ne a kula da gaskiyar cewa:
Yawan lodin filler yana raguwa inji Properties
Bai dace da high-lasticity ko high-damping ware abubuwan keɓancewa
(4) Ƙara Ƙaƙƙarfan Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙashin Ƙarƙwara
Bincike ya nuna cewa:
Maɗaukakin haɗin giciye → Maɗaukakin iskar oxygen → Ingantacciyar jinkirin harshen wuta
Wataƙila wannan tsarin yana da alaƙa da karuwa a cikin zafin jiki bazuwar thermal.
An yi nasarar aiwatar da wannan hanyar a ciki EPDM roba tsarin kuma ya dace da:
Pads na baturi da ake amfani da su a cikin matsakaita-zuwa-high yanayin yanayin zafi
Tsarin harshen wuta-retardant vibration damping roba sassa
2. Halayen Halayen Ƙashin Ƙarshe na Halogenated Rubbers
Halogenated rubbers a zahiri sun ƙunshi abubuwan halogen kuma yawanci suna nunawa:
Alamar Oxygen: 28-45
FPM (Fluororubber) oxygen index ya wuce 65
Babban abun ciki na halogen → mafi kyawun jinkirin wuta
Halin kashe kai bayan cire harshen wuta
A sakamakon haka, maganin kashe wuta na halogenated rubbers yana da sauƙin sauƙi, sau da yawa yana buƙatar ƙaramar ƙarfafawa kawai tare da masu kare wuta.
⚠ Duk da haka, saboda dokokin muhDuki (kamar RoHS kuma ISA ) da kuma trends a cikin sabuwar masana'antar makamashi, halogen-free mafita ana ƙara fifita su. Wannan shi ne babban dalilin da tartsatsi tDukafi na Halogen-Free Flame-Retardant Vibration Dampers.
3. Fasaha-Retardant Fasaha don Heterochain Rubbers
Mafi wakilci heterochain roba shine:
Dimethyl Silicone Rubber (VMQ)
Babban halayensa sun haɗa da:
Indexididdigar Oxygen kusan 25
Thermal bazuwar zafin jiki har zuwa 400-600 ° C
Kyakkyawan kwanciyar hankali mai zafi
Hanyoyin hana wuta na roba na silicone galibi sun ƙunshi:
Ƙara thermal bazuwar zafin jiki
Ƙara yawan adadin saura char bayan bazuwar
Ragewa yawan haɓakar iskar gas mai ƙonewa
Saboda, siliki roba ana amfani da shi sosai a ciki:
Pads Baturi masu zafi
Maɗaukakin ƙarshen halogen-ƙasasshen harshen wuta-retardant
Abubuwan buffer na kariya don lantarki da sabbin kayan aikin makamashi
Kammalawa
A harshen-retardant zane na kayayyakin roba dole ne a yi la'akari gabaɗaya bisa ga nau'in roba, yanayin aikace-aikace , kuma ka'idoji na doka.
Domin aikace-aikace irin su:
Kayan Batir
Halogen-Free Flame-Retardant Vibration Dampers
ana bada shawarar bada fifiko:
Tsarukan hana wuta mara halogen
Madaidaicin ƙirar ƙira mai yawa
Madaidaitan mafita tsakanin masu kashe wuta da aikin injina
Sai dai wasu nau’ikan roba na roba, galibi roba roba kayayyakin , kamar roba na halitta , su ne abubuwa masu ƙonewa ko masu ƙonewa.
