Nā Pōmaikaʻi o ka Magnesium Hydroxide Flame Retardant

He ʻano kuʻuna ka magnesium hydroxide o ka mea hoʻopihapiha e pale aku i ke ahi. Ke hōʻike ʻia i ka wela, hoʻoheheʻe ia a hoʻokuʻu i ka wai i hoʻopaʻa ʻia, e omo ana i ka nui o ka wela huna. Hoʻemi kēia i ka mahana o ka ʻili o ka mea hui i loko o nā lapalapa, e pale ana i ka hoʻoheheʻe ʻana o ka polymer a hoʻolulu i nā kinoea lapalapa i hana ʻia. He mea hoʻopihapiha lapalapa inorganic hoʻohiki ka magnesium hydroxide no nā hui polymer. E like me ka alumini hydroxide, hana ia ma ka omo ʻana i ka wela ma o ka hoʻoheheʻe ʻana o ka wela a me ka hoʻokuʻu ʻana i ka wai, e hana ana i mea ʻawaʻawa ʻole, haʻahaʻa ka uahi, a pili i ke kaiapuni, ʻoiai ʻo ka magnesium oxide hopena he paʻa a ʻaʻole ia e hoʻoulu i ka haumia lua.

Eia nō naʻe, i ka hoʻohālikelike ʻia me nā mea pale ahi organik i loaʻa i ka halogen, ʻo ka hoʻokō ʻana i ka hopena pale ahi like e pono ai ka lakio hoʻopiha ma luna o 50%. ʻOiai he inorganic ka magnesium hydroxide, ʻaʻole kūpono kona ʻili me nā substrates polymer. ʻO kēlā lakio hoʻopiha kiʻekiʻe, me ka ʻole o ka hoʻololi ʻana o ka ʻili, e hoʻohaʻahaʻa i nā waiwai mechanical o ka mea composite. No laila, pono ka hoʻololi ʻana o ka ʻili e hoʻomaikaʻi i kona kūlike me nā substrates polymer, e hōʻoia ana ʻaʻole i hoʻopilikia ʻia nā waiwai mechanical o ka mea i hoʻopiha ʻia - a i ʻole i hoʻonui ʻia i kekahi mau ʻano.

Ma loko o ke kaʻina hana pale ahi, ʻaʻole hana ka magnesium hydroxide i nā mea ʻino. Eia kekahi, hiki i kāna mau huahana palaho ke omo i ka nui o nā kinoea ʻawahia a me ka uahi i hana ʻia e ka puhi ʻana o ka rubber, plastics, a me nā polymers ʻē aʻe. Hoʻopili mau ka magnesium oxide ikaika i nā koena i hoʻoheheʻe ʻia i puhi ʻole ʻia, e kinai koke ana i nā lapalapa me ka hoʻopau ʻana i ka uahi a pale i ka kahe ʻana o ka heheʻe. He mea pale ahi inorganic kuʻuna ia e pili ana i ke kaiapuni.

I kēia manawa, hoʻohana nui ʻia ka alumini hydroxide ma Kina. Eia nō naʻe, i ka piʻi ʻana o ka mahana hana polymer, e palaho pinepine ana ka alumini hydroxide, e hōʻemi ana i kona pono flame-retardant. I ka hoʻohālikelike ʻana, hāʻawi ka magnesium hydroxide i nā pono penei:

1. ʻOi aku ka Mahana Hoʻoheheʻe Wela - Hoʻoheheʻe ka magnesium hydroxide ma 340°C, ʻo ia hoʻi he 100°C ke kiʻekiʻe ma mua o ka alumini hydroxide. ʻAe kēia i nā mahana hana plastic kiʻekiʻe, hoʻomaikaʻi i ka pono o ka extrusion, hoʻonui i ka plasticization, hoʻemi i ka manawa hoʻoheheʻe, a me ka hōʻoia ʻana i ka ʻōlinolino kiʻekiʻe me nā hemahema liʻiliʻi me ka mālama ʻana i ka ikaika o ka ʻili.
2. Ka nui o nā ʻāpana like a me ke kūlike maikaʻi - ʻO kona hoʻolaha like ʻana i nā ʻāpana e hōʻoiaʻiʻo i ka launa pū ʻana me nā substrates, e hoʻemi ana i ka hopena ma nā waiwai mechanical o ka huahana.
3. Ka Hoʻokumu ʻana o kahi Pale Pale - Ma hope o ka maloʻo ʻana i ka wā e puhi ai, ʻo ka magnesium oxide hopena he mea ikaika kiʻekiʻe, kūpaʻa i ka wela e hana ana ma ke ʻano he pale pale, e hoʻokaʻawale ana i nā lapalapa a me nā kinoea ʻawahia. Hoʻopau pū ka Magnesium hydroxide i nā kinoea waikawa (SO₂, NOx, CO₂) i hana ʻia i ka wā e puhi ai ka plastic.
4. Ka Hana Kiʻekiʻe no ka Hoʻoheheʻe ʻana a me ka Hoʻopau ʻana i ka Uahi - Hōʻike ia i nā hiki ke pale ahi a me ka hoʻopau ʻana i ka uahi me ka emi ʻana o ka abrasive i nā lako, no laila e hoʻolōʻihi ai i ke ola o ka mīkini.
5. Kumukūʻai Kūpono - ʻO ka magnesium hydroxide flame retardant ka hapalua o ke kumukūʻai o ka alumini hydroxide. ʻO kona hiki ke hoʻopiha kiʻekiʻe e hōʻemi nui i nā kumukūʻai hana.
