E koho i ka'ōlelo 
Koe wale no kekahi mau ano o ka synthetic rubber, ka hapanui nā huahana ʻōpala synthetic , like pulupulu maoli , he mea hiki ke puhi a puhi paha . Ma nā ʻoihana e like me ikehu hou, ʻōnaehana pākaukau , a lako uila , ua kau ʻia nā koi ʻoi aku ka pale ahi ma luna o nā ʻāpana lāʻau, ʻoi aku hoʻi no nā huahana e like me Nā Paʻa Paʻa a ʻO nā mea hoʻoheheʻe haʻahaʻa me ka Halogen-Free Flame-Retardant.
I kēia manawa, ʻo nā ala ʻenehana nui no ka hoʻomaikaʻi ʻana i ka ka hoʻopaʻa ʻana i ka lapalapa ahi o nā huahana rubber komo:
Hoʻohui nā mea pale ahi a i ʻole nā mea hoʻopiha ahi
Hoʻololi hoʻohuihui me nā mea pale ahi
Hoʻolauna nā hui hana pale ahi i ka wā polymerization
Hoʻonui i ka mānoanoa crosslink o na hua laau
Hāʻawi nā ʻāpana aʻe i kahi wehewehe pōkole a me ka wehewehe ʻana o nā ʻenehana pale ahi.
1. Nā ʻenehana hoʻopaʻa ahi no nā Rubber Hydrocarbon
1.1 Nā ʻano o nā Rubber Hydrocarbon
ʻO nā pulupulu wai komo nui:
NR (Natural Rubber)
SBR (Styrene-Butadiene Rubber)
BR (Butadiene Rubber)
IIR (Butyl Rubber)
EPR / EPDM (Ethylene Propylene Rubber)
ʻOiai NBR (Nitrile Rubber) ʻAʻole ia he typical hydrocarbon rubber, its nā ʻano lapaʻau pale ahi ua like a kūkākūkā pinepine ʻia ma nā noi ʻenekinia.
ʻO nā hiʻohiʻona nui o nā ʻōpala hydrocarbon:
Ke kaupalena ana i ka Oxygen Index (LOI): ma kahi o. 19–21
Ka wela wela: 200–500°C
ʻAʻole hiki ke pale i ka lapalapa ahi a me ka pale wela
Ka hooulu ana i na huina nui o nā kinoea lapalapa i ka wā e puhi ai
No laila, ke hoʻohana ʻia i loko Nā Paʻa Paʻa, nā pā hoʻoheheʻe ʻoihana , a i ʻole ʻāpana hoʻokaʻawale haʻalulu maʻamau , pono ka hoʻololi ʻana i ka lapalapa ahi.
1.2 Nā ʻano hana maʻamau e pale ai i ke ahi no nā Rubber Hydrocarbon
(1) Hoʻohui ʻia me nā Polymers Paʻa-Ala
Ma ka hoʻohui ʻana i nā ʻōpala hydrocarbon me nā polymers pale ahi e like me:
Polyvinyl Chloride (PVC)
Polyethylene Klorina (CPE)
Polyethylene Chlorosulfonated (CSM)
Ethylene-Vinyl Acetate (EVA)
hiki ke hoʻomaikaʻi ʻia ka pale ʻana o ka lapalapa i kekahi ʻano. I ka wā o ka hui ʻana, pono e nānā pono ʻia:
Hoʻopili waiwai
Hoʻolālā ʻōnaehana hui pū
Hoʻohana mau ʻia kēia ʻano hana no Nā Pākuʻi Paʻa a i ʻole nā mea hoʻoheheʻe ʻole kiʻekiʻe.

ʻO ka hoʻohui ʻana o nā mea pale ahi ʻo ia ke ʻano koʻikoʻi no ka hoʻonui ʻana i ka hoʻopaneʻe ʻana o ka lapalapa i nā ʻōpala hydrocarbon a hiki ke hoʻomaikaʻi hou ʻia ma o ʻōnaehana synergistic.
ʻO nā mea hoʻopaʻa ahi ma muli o ka halogen (nā hoʻonā kuʻuna):
Hexachlorocyclopentadiene derivatives
Decabromodiphenyl ether
Paraffin chlorinated
Nā mea pale ahi synergistic inorganic:
Antimony trioxide (Sb₂O₃) (hoʻohana mau ʻia)
Zinc borate
Aluminum hydroxide
Ammonium chloride
⚠ Nā memo koʻikoʻi:
ʻAʻole pono e loaʻa i nā mea hoʻopaʻa ahi kumu halogen manuahi halogen , inā ʻaʻole hiki iā lākou:
E hoʻoheheʻe i nā mea hana a me nā poni
E hōʻemi i ka hana hoʻokaʻawale uila
Hoʻopilikia maikaʻi i ka pale ʻana i ka wā kahiko
I ka ikehu hou a ʻoihana uila, ʻO nā mea hoʻoheheʻe haʻahaʻa me ka Halogen-Free Flame-Retardant ua lilo i mea nui, e alakaʻi ana i kahi makemake ikaika no ʻōnaehana pale ahi ʻole halogen.
(3) Hoʻohui i nā mea hoʻopiha piha ʻole i ke ahi
Hoʻohana pinepine ʻia nā mea hoʻopihapiha:
Kāleka kalapona
pālolo Kaolin
Talc
Silika hoʻohuehu
Aluminum hydroxide
Hoʻomaikaʻi kēia ʻano hana i ka pale ahi ma:
E hOEMi ana i ka mahele o mea ola kino
Ke hoʻohana nei i ka hopena decomposition endothermic o na mea hoopiha
ʻo kahi laʻana:
Kāleka kalapona a alumini hydroxide e komo i ka wela nui i ka wā palaho
Eia naʻe, pono e nānā i ka ʻoiaʻiʻo:
Hoʻemi ʻia ka hoʻouka ʻana o ka hoʻopiha piha ʻano mekini
ʻAʻole kūpono no kiʻekiʻe-elasticity a i ʻole kiʻekiʻe-damping vibration kaʻawale
(4) Ke hoʻonui nei i ka nui o ka Rubber Crosslink Density
Ua hōʻike nā haʻawina i kēlā:
ʻOi aku ke kiʻekiʻe o ka crosslink density → Higher oxygen index → Hoʻomaikaʻi i ka hoʻopaneʻe ʻana o ka lapalapa
Pili paha kēia ʻano me ka piʻi i ka wela decomposition wela.
Ua hoʻohana maikaʻi ʻia kēia ʻano hana ma ʻO nā ʻōnaehana ʻōpala EPDM a ua kūpono no:
Hoʻohana ʻia ʻo Pads Battery ma nā wahi wela waena a kiʻekiʻe
ʻO nā ʻāpana lāʻau lapaʻau e hoʻopaʻa i ka lapalapa ahi
2. Nā ʻano ʻano pale ahi o nā Rubber Halogenated
ʻO nā pulu halogenated Loaʻa nā mea halogen a hōʻike maʻamau:
Helu 'oxygen: 28–45
ʻO FPM (Fluororubber) ka helu o ka oxygen ma mua o 65
ʻOi aku ka nui o nā mea halogen → ʻoi aku ka maikaʻi o ka pale ahi
ʻO ka hana hoʻopau iā ia iho ma hope o ka wehe ʻana i ke ahi
ʻO ka hopena, ʻoi aku ka maʻalahi o ka mālama ʻana i ka lapalapa ahi o nā lāʻau halogenated, koi pinepine i ka hoʻoikaika liʻiliʻi wale nō me nā mea pale ahi.
⚠ Eia naʻe, ma muli o hooponopono kaiapuni (e like me RoHS a REACH ) a me nā ʻano i loko o ka ʻoihana ikehu hou, nā hāʻina halogen mahuahua ka makemake. ʻO kēia ke kumu nui o ka hoʻohana nui ʻana ʻO nā mea hoʻoheheʻe haʻahaʻa me ka Halogen-Free Flame-Retardant.
3. Nā ʻenehana hoʻopaʻa ahi no nā Heterochain Rubbers
ʻO ka ʻelele nui loa huila heterochain ʻo ia:
ʻO Dimethyl Silicone Rubber (VMQ)
ʻO kāna mau hiʻohiʻona nui:
Oxygen index ma kahi o 25
ʻO ka wela wela a hiki i 400–600°C
Paʻa wela kiʻekiʻe maikaʻi
Hoʻokomo nui ʻia nā mīkini pale ahi o ka silikoni:
Ke piʻi nei mahana decomposition wela
Hoʻonui i ka nui o koena char ma hope o ka palaho
E hOEMi ana i ka ka helu o nā kinoea puhi
Ma ka hopena, kalapona silicone hoʻohana nui ʻia ma:
Nā Paʻa Paʻa Kiʻekiʻe
ʻO nā mea hoʻoheheʻe ʻana i ka halogen-free flame-retardant kiʻekiʻe
Nā ʻāpana pale pale no nā lako uila a me nā mea ikehu hou
Ka hopena
ʻO ka hoʻolālā pale ahi o huahana lāʻau pono e noonoo nui ia ma muli o ʻano lāʻau lapaʻau, kaiapuni noi , a koi hooponopono.
No nā noi e like me:
Nā Paʻa Paʻa
ʻO nā mea hoʻoheheʻe haʻahaʻa me ka Halogen-Free Flame-Retardant
paipai ʻia e hana mua:
Nā ʻōnaehana pale ahi ʻole halogen
ʻO ka hoʻolālā ʻana o ka mānoanoa crosslink kūpono
ʻO nā hoʻonā kaulike ma waena o nā mea hoʻopiha ahi-retardant a me ka hana mechanical
Koe wale no kekahi mau ano o ka synthetic rubber, ka hapanui nā huahana ʻōpala synthetic , like pulupulu maoli , he mea hiki ke puhi a puhi paha.
