ʻO ka helu ahi o ka papa kaapuni paʻi e pili ana i ka helu ahi o ka papa. Hana ʻia nā papa kaapuni i paʻi ʻia me ke aniani fiber me ka helu ahi o FR-4. He kiʻekiʻe ka helu ahi o kēia mea a hiki ke pale i ke ahi i kekahi ʻano. ʻOiaʻiʻo, e like me nā mea e like me nā koi noi a me nā koi palekana, hiki i ka helu ahi o nā papa kaapuni i paʻi ʻia ke hoʻohana i nā mea like ʻole a me nā kūlana.
ʻO ke kūlana kikoʻī o UL94v0 ʻo ia ka mea i hōʻea i ka papa kaapuni i ke kūlana ahi. ul94 lako a me nā mea hana e hoʻāʻo ana i ka hoʻāʻo ʻana o nā mea plastik, me ka inoa maʻamau, ka laulā o ka noi, ka papa helu, nā kūlana pili, etc. UL94 Plastic material combustion test - Classification:
1) HB pae: Ho'āʻo Puhi Hoʻomoe
2) V0-V2 pae: Vertical Burning Ho'āʻo Vertical Burning Test
Hoʻonui ʻia ka pae lapalapa ahi o nā plastics mai HB, V-2, V-1 a i V-0 i kēlā me kēia ʻanuʻu:
UL 94 (Ka hoʻāʻo ʻana i ka flammability no nā mea plastik)
HB: ʻO ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa ahi ma ke kūlana UL94. No nā laʻana 3 a 13 mm mānoanoa, e puhi i ka liʻiliʻi ma lalo o 40 mm i kēlā me kēia minuke a no nā laʻana 3 mm ka mānoanoa, e puhi i ka wikiwiki ma lalo o 70 mm i kēlā me kēia minuke a i ʻole e pio ma mua o ka hōʻailona 100 mm.
V-2: Ua pio ke ahi i loko o 30 kekona ma hope o ʻelua mau hoʻāʻo hoʻāhu 10-kekona o ka hāpana. Hiki ke puhi i ka pulupulu 30cm.
V-1: Ua pio ke ahi i loko o 30 kekona ma hope o ʻelua mau hoʻāʻo puhi ahi he 10 kekona o ka hāpana. Mai puhi i ka pulupulu 30cm.
V-0: Ua pio ka lapalapa i loko o 10 kekona ma hope o ʻelua mau hoʻāʻo ʻana he 10-kekona ma ka laʻana.
E like me ka pae kiʻekiʻe mai lalo a hiki i ka mahele kiʻekiʻe penei: 94HB/94VO/22F/ CIM-1 / CIM-3 / FR-4, hiki ke hoʻokaʻawale ʻia nā hiʻohiʻona pale ahi o ka māhele papa i 94V-0 / V- 1 /V-2, 94-HB ʻehā ʻano; 94HB: papa maʻamau, ʻaʻohe ahi (ʻo ka papa haʻahaʻa haʻahaʻa, make kuʻi, ʻaʻole hiki ke hana i ka papa mana) 94V0: papa pale ahi (make kuʻi) 22F: ʻaoʻao hoʻokahi hapa aniani papa fiber (make kuʻi) CIM-1: hoʻokahi- ʻaoʻao ʻaoʻao papa puluniu aniani (pono e lolouila lolouila, ʻaʻole hiki ke make i ke kuʻi ʻana) CIM-3: ʻaoʻao ʻelua ʻaoʻao hapa aniani papa fiber FR-4: papa ʻaoʻao ʻelua ʻaoʻao aniani fiber.
ʻO ke koʻikoʻi koʻikoʻi nā papa āpau o Shenzhen Lianchuang Electronics Co., Ltd, ʻike ʻia ka helu ahi me 94v-0!
ʻO nā papa halogen-free no nā papa kaapuni paʻi e pili ana i nā mea halogen-free i hoʻohana ʻia i ka hana ʻana i nā papa kaapuni paʻi. ʻO nā mea halogen-free e pili ana i nā mea i loaʻa ʻole nā mea halogen e like me ka chlorine a me ka bromine. ʻOi aku ka maikaʻi o ke kaiapuni a me ka palekana ma mua o nā mea halogen kuʻuna, a hiki ke hōʻemi i ka pōʻino i ke kaiapuni a me ke kino kanaka. I kekahi mau ʻāina a me nā ʻāina, ua lilo ka hoʻohana ʻana i nā mea halogen-free no ka hana ʻana i nā papa kaapuni paʻi i ke kānāwai a i ʻole ke kūlana ʻoihana e hāpai i ka hoʻomohala hoʻomau a me ka pale ʻana i ke kaiapuni.
FAQs
Hoʻokaʻawale ʻia ka hapa nui o nā PCB e like me FR-4, e hōʻike ana ua hoʻokō lākou i kekahi mau koi hana, a me nā koi V0 o ka UL (Underwriters Laboratories) 94 flammability testing standard.
Hoʻohana ʻia ʻo UL 94 e ana i ka nui o ke ahi a me nā hiʻohiʻona e pili ana i nā laʻana maʻamau. ʻO ka nui o ka laʻana he 12.7mm e 127mm, me ka ʻokoʻa o ka mānoanoa mai 0.8mm a 3.2mm.
ʻO ka PCB manuahi halogen he papa kaapuni i paʻi ʻia me nā mea halogen liʻiliʻi. ʻO nā mea halogen nui e make ai ke ola, ʻo ia ka chlorine, fluorine, bromine, astatine, a me iodine. ʻO ka PCB manuahi halogen he emi ma mua o 900 ppm o ka bromine a i ʻole chlorine. Eia kekahi, aia ka papa ma lalo o 1500 ppm o nā mea halogen.
ʻO ka mea hou aku, hoʻohaʻahaʻa nā halogens i ka maikaʻi o ka ea ma o ka hoʻolaha ʻana i ka hoʻokumu ʻana o ka ozone. Ma ka pae honua, he mea haumia ka ozone (a me ke kinoea hoʻomehana honua) a hiki i ka hoʻolaha lōʻihi ke alakaʻi i nā maʻi hanu, me ka hānō, a e pōʻino ana i nā mea kanu.
ʻAʻole loaʻa manuahi nā metala alkali a me nā halogen ma ke ʻano no ka mea he ʻano hoʻoikaika. Aia lākou ma kahi kūlana hui.
