I kēia mau makahiki i hala iho nei, ua ulu nui ka hopohopo e pili ana i ka pōʻino o ke kaiapuni a me ke olakino i hoʻokumu ʻia e ka halogen-based flame retardants i hoʻohana ʻia i nā plastics.ʻO ka hopena, ua loaʻa i nā mea pale ahi non-halogen ke kaulana ma muli o ko lākou mau ʻano palekana a ʻoi aku ka paʻa.
Ke hana nei nā mea pale ahi ʻole halogen ma ka hoʻopau ʻana i nā kaʻina hana hoʻopau i ka wā e ʻike ʻia ai nā plastik i ke ahi.
1. Hoʻokō lākou i kēia ma ke kino a me ke kemika keʻakeʻa i nā kinoea puhi ahi i hoʻokuʻu ʻia i ka wā puhi.ʻO kekahi o nā hana maʻamau ma o ka hoʻokumu ʻana i kahi papa kalapona pale ma ka ʻili o ka plastic.
2. Ke ʻike ʻia i ka wela, e loaʻa i nā mea hoʻopaʻa ahi ʻole halogen i kahi hopena kemika, kahi e hoʻokuʻu ai i ka wai a i ʻole nā kinoea hiki ʻole ke puhi.Hoʻokumu kēia mau kinoea i mea pale ma waena o ka plastic a me ka lapalapa, no laila e hoʻolohi i ka laha ʻana o ke ahi.
3. Hoʻopau ka halogen-free flame retardants a hoʻokumu i kahi papa carbonized paʻa, i kapa ʻia ʻo char, e hana ana ma ke ʻano he pale kino, e pale ana i ka hoʻokuʻu hou ʻana o nā kinoea lapalapa.
4. Eia kekahi, hiki i ka halogen-free flame retardants ke hoʻoheheʻe i nā kinoea hoʻopau ʻia ma o ka hoʻoheheʻe ʻana a me ka hopu ʻana i nā radical manuahi a me nā mea hiki ke hoʻopau ʻia.Hoʻopau maikaʻi kēia hopena i ke kaulahao o ka hoʻopau ʻana, e hoʻemi hou i ka ikaika o ke ahi.
ʻO ka Ammonium polyphosphate kahi mea pale ahi phosphorus-nitrogen halogen-free flame retardant.Loaʻa iā ia ka hana pale ahi kiʻekiʻe i loko o nā plastics me nā hiʻohiʻona non-toxic a me ke kaiapuni.
Hoʻohana Plastics
Hoʻohana pinepine ʻia nā plastic flame retardant e like me FR PP, FR PE, FR PA, FR PET, FR PBT a pēlā aku i ka ʻoihana kaʻa no nā kaʻa o loko, e like me nā dashboards, panels puka, nā ʻāpana noho, nā pā uila, nā pā kelepona, pale ahi. nā panela uila, 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 maʻamau flammability plastics i hoʻokuʻu ʻia e ka Underwriters Laboratories (USA).Hoʻokaʻawale ka maʻamau i nā plastics e like me ke ʻano o ka puhi ʻana i nā ʻano ʻano like ʻole a me ka mānoanoa ʻāpana mai ka haʻahaʻa haʻahaʻa a hiki i ka nui o ka lapalapa ahi i loko o nā papa ʻeono.
| Helu UL 94 | Wehewehe o ka helu |
| V-2 | Hoʻopau ke ahi i loko o 30 kekona ma kahi ʻāpana e hiki ai i nā kulu o ka plastic flammable vertical. |
| V-1 | Hoʻopau ke ahi i loko o 30 kekona ma kahi ʻaoʻao kūpaʻa e ʻae ai i nā kulu o ka plastik ʻaʻole i wela. |
| V-0 | Hoʻopau ke ahi i loko o 10 kekona ma kahi ʻaoʻao kūpaʻa e ʻae ai i nā kulu o ka plastik ʻaʻole i wela. |
