Kumumanaʻo
I nā makahiki i hala iho nei, ua nui ka hopohopo e pili ana i nā pilikia kaiapuni a me ke olakino i kau ʻia e nā mea pale ahi halogen i hoʻohana ʻia i loko o nā plastics. ʻO ka hopena, ua loaʻa i nā mea pale ahi non-halogen ka kaulana ma muli o ko lākou ʻano palekana a hoʻomau.
Hana nā mea hoʻomaha lapalapa halogen-free ma ke keakea ʻana i nā kaʻina hana puhi e hana ʻia ke hōʻike ʻia nā plastics i ke ahi.
1. Hoʻokō lākou i kēia ma ke kino a me ke kemika e hoʻopilikia ana i nā kinoea lapalapa i hoʻokuʻu ʻia i ka wā e puhi ai. ʻO kekahi o nā ʻano hana maʻamau ma o ka hoʻokumu ʻana o kahi papa kalapona pale ma luna o ka ʻili o ka plastic.
2. Ke hōʻike ʻia i ka wela, hana nā mea pale ahi halogen-free i kahi hopena kemika, kahi e hoʻokuʻu ai i ka wai a i ʻole nā kinoea ʻē aʻe i hiki ʻole ke puhi. Hoʻokumu kēia mau kinoea i kahi pale ma waena o ka plastic a me ka lapalapa, no laila e hoʻolohi ana i ka laha ʻana o ke ahi.
3. Hoʻopala nā mea pale ahi halogen-free a hana i kahi papa carbonized paʻa, i ʻike ʻia ʻo char, ka mea e hana ma ke ʻano he pale kino, e pale ana i ka hoʻokuʻu hou ʻana o nā kinoea lapalapa.
4. Eia kekahi, hiki i nā mea pale ahi halogen-free ke hoʻoheheʻe i nā kinoea hiki ke puhi ʻia ma o ka ionizing a me ka hopu ʻana i nā radical manuahi a me nā ʻāpana lapalapa. Hoʻopau maikaʻi kēia hopena i ka hopena kaulahao o ke ahi, e hoʻemi hou ana i ka ikaika o ke ahi.
He mea pale ahi ʻole ka phosphorus-nitrogen halogen-free ka Ammonium polyphosphate. Loaʻa iā ia ka hana pale ahi kiʻekiʻe i loko o nā plastics me nā hiʻohiʻona ʻawahia ʻole a me ke kaiapuni.
Noi ʻana i nā palakiko
ʻO nā palakiko pale ahi e like me FR PP, FR PE, FR PA, FR PET, FR PBT a pēlā aku e hoʻohana pinepine ʻia i ka ʻoihana kaʻa no nā loko o ke kaʻa, e like me nā dashboards, nā panela puka, nā ʻāpana noho, nā pā uila, nā pā uwea, nā panela uila pale ahi, nā mea hoʻololi, nā pā uila, a me ka lawe ʻana i ka wai, nā paipu kinoea.
Kūlana pale ahi (UL94)
ʻO UL 94 kahi kūlana lapalapa plastik i hoʻokuʻu ʻia e nā Underwriters Laboratories (USA). Hoʻokaʻawale ke kūlana i nā plastik e like me ke ʻano o ko lākou puhi ʻana i nā ʻano like ʻole a me nā mānoanoa ʻāpana mai ka mea pale ahi haʻahaʻa loa a i ka mea pale ahi nui loa i nā hoʻokaʻawale ʻeono.
| Ka helu UL 94 | Ka Wehewehena o ka Loiloi |
| V-2 | Hoʻopau ʻia ke kuni ʻana i loko o 30 kekona ma kahi ʻāpana e ʻae ai i nā kulu o ka palakiko lapalapa kū pololei. |
| V-1 | Hoʻōki ka ʻā ʻana i loko o 30 kekona ma kahi ʻāpana kū pololei e ʻae ana i nā kulu o ka palakiko ʻaʻole e ʻā. |
| V-0 | Hoʻōki ka ʻā ʻana i loko o 10 kekona ma kahi ʻāpana kū pololei e ʻae ana i nā kulu o ka palakiko ʻaʻole e ʻā. |
