ʻO nā pono o ka Magnesium Hydroxide Flame Retardant

ʻO ka Magnesium hydroxide kahi ʻano kuʻuna o ka hoʻopiha ʻana i ka lapalapa ahi. Ke ʻike ʻia i ka wela, hoʻoheheʻe ʻia a hoʻokuʻu i ka wai i hoʻopaʻa ʻia, e komo i ka nui o ka wela huna. Hoʻemi kēia i ka wela o ka ʻili o ka mea i hoʻohui ʻia i ke ahi, kaohi ʻana i ka decomposition polymer a me ka hoʻoluʻu ʻana i nā kinoea lapalapa i hana ʻia. ʻO ka Magnesium hydroxide kahi mea hoʻopiha ahi-retardant inorganic no nā composites-based polymer. E like me ka alumini hydroxide, hana ia ma ka lawe ʻana i ka wela ma o ka decomposition thermal a me ka hoʻokuʻu ʻana i ka wai, ʻaʻole ia he mea ʻawaʻawa, haʻahaʻa-uwahi, a me ke kaiapuni, no ka mea, paʻa ka hopena o ka magnesium oxide a ʻaʻole ia e hoʻohaumia i ka lua.

Eia nō naʻe, ke hoʻohālikelike ʻia me nā mea hoʻopaʻa ahi o ka halogen, ʻo ka loaʻa ʻana o ka hopena flame-retardant like e pono ai ka hoʻopiha piha ʻana ma luna o 50%. No ka mea he anorganic ka magnesium hydroxide, ʻaʻohe kūpono o kona ʻili me nā substrate polymer. ʻO kēlā ʻano hoʻopihapiha hoʻopihapiha kiʻekiʻe, me ka ʻole o ka hoʻololi ʻana i ka ʻili, e hoʻohaʻahaʻa i nā waiwai mechanical o ka mea hoʻohui. No laila, pono ka hoʻololi ʻana o ka ʻili no ka hoʻomaikaʻi ʻana i kona kūlike me nā substrate polymer, e hōʻoia ana ʻaʻole i hoʻohālikelike ʻia nā waiwai mechanical o ka mea i hoʻopiha ʻia-a i ʻole i hoʻonui ʻia i kekahi mau ʻano.

I loko o ke kaʻina hana pale ahi, ʻaʻole hana ka magnesium hydroxide i nā mea ʻino. Eia kekahi, hiki i kāna mau huahana decomposition ke komo i ka nui o nā kinoea ʻawaʻawa a me ka uahi i hana ʻia e ka puhi ʻana o ka lāʻau, plastics, a me nā polymers ʻē aʻe. Hoʻopili mau ka magnesium oxide i nā koena hoʻoheheʻe ʻole ʻia, hoʻopau koke i ke ahi me ka hoʻopau ʻana i ka uahi a me ka pale ʻana i ka hoʻoheheʻe ʻana. He mea hoʻopaʻa ahi kuʻuna kaiaola.

I kēia manawa, hoʻohana nui ʻia ka alumini hydroxide ma Kina. Eia nō naʻe, ke piʻi aʻe ka mahana o ka hoʻoponopono polymer, hiki ke hoʻoheheʻe ʻia ka alumini hydroxide, e hōʻemi ana i ka pono o ka lapalapa ahi. I ka hoʻohālikelike ʻana, hāʻawi ka magnesium hydroxide i kēia mau pono:

1. ʻOi aku ka wela o ka wela wela - hoʻoheheʻe ʻia ka magnesium hydroxide ma 340 ° C, ʻo ia ka 100 ° C ma mua o ka alumini hydroxide. Hiki i kēia ke kiʻekiʻe o ka hoʻomaʻamaʻa plastik, hoʻomaikaʻi i ka pono extrusion, hoʻonui i ka plasticization, hōʻemi i ka manawa hoʻoheheʻe ʻana, a me ka hōʻoia ʻana i ka nani o ka ʻili kiʻekiʻe me ka liʻiliʻi o nā hemahema ʻoiai e mālama ana i ka ikaika peel ikaika.
2. ʻO Uniform Particle Size & Good Compatibility - ʻO kāna puʻupuʻu puʻupuʻu e hōʻoia i ka hoʻohālikelike maikaʻi ʻana me nā substrates, e hōʻemi ana i ka hopena i nā waiwai mechanical o ka huahana.
3. Ka Hoʻokumu ʻia ʻana o kahi pale pale - Ma hope o ka maloʻo ʻana i ka wā o ka puhi ʻana, ʻo ka magnesium oxide ka hopena he ikaika kiʻekiʻe, wela ka mea e hana ai ma ke ʻano he pale pale, hoʻokaʻawale i nā lapalapa a me nā kinoea ʻona. Hoʻopau pū ka Magnesium hydroxide i nā kinoea ʻakika (SO₂, NOx, CO₂) i hana ʻia i ka wā o ka puhi ʻana i ka plastic.
4. ʻO ke kiʻekiʻe Decomposition Efficiency & Smoke Suppression - Hōʻike ia i ka ikaika o ka lapalapa ahi a me ka hiki ke hoʻopaʻa i ka uahi ʻoiai ʻoi aku ka liʻiliʻi o ka abrasive i nā mea hana, a laila e hoʻolōʻihi i ke ola o ka mīkini.
5. ʻO ke kumu kūʻai - ʻo Magnesium hydroxide flame retardant ka hapalua o ke kumukūʻai o ka alumini hydroxide. ʻO kona kūlana hoʻopihapiha hoʻopihapiha nui e hoʻemi nui i nā kumukūʻai hana.
