No nā mea e pono ai ka lapalapa ahi o ka latex sponge, ʻo kēia ka nānā ʻana e pili ana i kekahi mau mea pale ahi e loaʻa nei (aluminum hydroxide, zinc borate, alumini hypophosphite, MCA) me nā ʻōlelo paipai:
I. Ka Ike ana o ka Hoohana Hoopae Ana i ke ahi
Aluminum Hydroxide (ATH)
Pono:
- Pili kaiapuni, haʻahaʻa ke kumu kūʻai.
- Hana ma ka endothermic decomposition a me ka hoʻokuʻu ʻana i ka mahu wai, kūpono no nā ʻōnaehana halogen.
Nā hemahema:
- Pono ka hoʻouka kiʻekiʻe (30-50 phr) no ka pono, hiki ke hoʻopilikia i ka elasticity a me ka nui o ka sponge.
Hoʻohana:
- He kūpono no nā ʻano hana pale ahi maʻamau.
- Manaʻo ʻia e hui pū me nā synergists (e laʻa, zinc borate).
Zinc Borate
Pono:
- ʻO Synergistic flame retardant, hoʻonui i ka pono ATH.
- Hoʻoikaika i ka hana char a hoʻopaʻa i ka uahi.
Nā hemahema:
- He palena palena ke hoʻohana wale ʻia; Pono e hui pū me nā mea pale ahi ʻē aʻe.
Hoʻohana:
- Manaʻo ʻia ma ke ʻano he synergist no ATH a i ʻole alumini hypophosphite.
Aluminum Hypophosphite
Pono:
- ʻO ka maikaʻi loa, ʻaʻohe halogen, haʻahaʻa haʻahaʻa (10-20 phr).
- ʻO ke kūpaʻa wela maikaʻi, kūpono no nā koi hoʻopaʻa ahi kiʻekiʻe.
Nā hemahema:
- ʻO ke kumukūʻai kiʻekiʻe.
- Pono ka hōʻoia ʻana me nā ʻōnaehana latex.
Hoʻohana:
- He kūpono no nā kūlana hoʻopaneʻe ahi kiʻekiʻe (e laʻa, UL94 V-0).
- Hiki ke hoʻohana hoʻokahi a hui pū paha.
MCA (Melamine Cyanurate)
Pono:
- Pākuʻi ʻia i ka lapalapa ahi, hoʻopau i ka uahi.
Nā hemahema:
- Hoʻopuehu maikaʻi ʻole.
- Hiki ke hoʻopilikia i ka huʻa.
- ʻO ka mahana decomposition kiʻekiʻe (~ 300 ° C), kūpono ʻole me ka hana ʻana o ka latex haʻahaʻa.
Hoʻohana:
- ʻAʻole ʻōlelo ʻia ma ke ʻano he mea nui; koi ʻia ka hōʻoia hoʻokolohua.
II. Manaʻo ʻia a me nā manaʻo hana
Hoʻopuka 1: ATH + Zinc Borate (Koho Hoʻokele)
Huina:
- Aluminum Hydroxide (ATH): 30-40 phr
- Zinc Borate: 5-10 phr
- Dispersant (eg, silane coupling agent): 1-2 phr (hoʻomaikaʻi i ka dispersibility)
Nā hiʻohiʻona:
- ʻO ke kumukūʻai haʻahaʻa, pili kaiapuni.
- He kūpono no ka hoʻopaneʻe ʻana o ke ahi maʻamau (e laʻa, UL94 HF-1).
- Hiki ke hoʻemi iki i ke kūpaʻa o ka sponge; Pono ka hoʻonui ʻana i ka Vulcanization.
Hana 2: Aluminum Hypophosphite + Zinc Borate (Ke Koho Hoʻoikaika Kiʻekiʻe)
Huina:
- Aluminum Hypophosphite: 15-20 phr
- Zinc Borate: 5-8 phr
- Plasticizer (e laʻa, wai paraffin): 2-3 phr (hoʻomaikaʻi i ka hana ʻana)
Nā hiʻohiʻona:
- Kiʻekiʻe flame retardancy pono, haʻahaʻa hoʻouka.
- He kūpono no nā hiʻohiʻona makemake nui (e laʻa, ke kuni kūpaʻa V-0).
- Pono ka hoʻāʻo ʻana o ka alumini hypophosphite me ka latex.
Hana 3: ATH + Aluminum Hypophosphite (Koho Kaulike)
Huina:
- Aluminum Hydroxide: 20-30 phr
- Aluminum Hypophosphite: 10-15 phr
- Zinc Borate: 3-5 phr
Nā hiʻohiʻona:
- Hoʻohālikelike i ke kumukūʻai a me ka hana.
- Hoʻemi i ka hilinaʻi ʻana i ka lapalapa ahi hoʻokahi, e hōʻemi ana i ka hopena i nā waiwai kino.
III. Nā Manaʻo Kaʻina Hana
Hoʻopuehu:
- Pono e hoʻoneʻe ʻia nā mea pale ahi a hiki i ≤5μm e pale aku i ka hoʻopili ʻana i ke ʻano o ka ʻūhā.
- Manaʻo ʻia ka hoʻopuehu ʻana i ka latex a i ʻole nā mea hoʻohui kiʻekiʻe.
Nā Kūlana hoʻōla:
- E hoʻomalu i ka mahana hoʻōla (maʻamau ʻo 110-130°C no ka latex) e pale i ka palaho mua o nā mea pale ahi.
Ka ho'āʻo hana:
- Nā ho'āʻo pono: Oxygen Index (LOI), Vertical Burn (UL94), Density, Resilience.
- Inā ʻaʻole lawa ka lohi ʻana o ke ahi, e hoʻonui mālie i ka alumini hypophosphite a i ʻole ATH ratio.
IV. Nā Manaʻo Hou
Hoʻāʻo MCA:
- Inā hoʻāʻo ʻia, e hoʻohana i ka 5-10 phr i nā pūʻulu liʻiliʻi e nānā i ka hopena i ka like ʻana o ka huʻa.
Nā Palapala Kaiapuni:
- E hōʻoia i ka hoʻokō ʻana o nā mea pale ahi i koho ʻia me RoHS/REACH no nā hoʻokuʻu aku.
ʻO nā hui like ʻole:
- E noʻonoʻo e hoʻohui i ka nanoclay liʻiliʻi (2-3 phr) e hoʻomaikaʻi i nā hopena pale char.
