Melamine Cyanurate Melamine Cyanurate

Melamine Cyanurate(MCA) he mea hoʻohana maʻamau i ka lapalapa ahi e pili ana i ka honua, hoʻohana nui ʻia i nā mea polymer e like me polyamide (Nylon, PA-6/PA-66), epoxy resin, polyurethane, polystyrene, polyester (PET, PBT), polyolefin a me halogen- uwea manuahi a me ka uwea. ʻO kāna mau waiwai pale ahi maikaʻi loa, haʻahaʻa haʻahaʻa a me ke kūpaʻa wela maikaʻi ua lilo ia i mea hopohopo nui a hoʻohana ʻia i nā ʻoihana uila, nā kaʻa a me ke kūkulu ʻana.

ʻO ka Melamine Cyanurate kahi hui i hana ʻia e ka hopena o ka Melamine a me ka cyanuric acid. ʻO ka molecular lattice structure i hoʻokumu ʻia e ka hydrogen bonding i loaʻa nā mea momona waiwai. ʻAe kēia i ka Melamine Cyanurate e hoʻokuʻu i kahi nui o ka nitrogen i nā wela kiʻekiʻe, a laila e pale ai i ka laha ʻana o ke ahi. Hoʻoholo kona ʻano kemika he kūpaʻa wela maikaʻi, ikaika mechanical a me ka hopena pale ahi maikaʻi loa.

Eia kekahi, ʻaʻole i loaʻa i ka MCA nā mea halogen pōʻino, no laila ua hoʻohana nui ʻia i nā manawa he nui me nā koi o ke kaiapuni a me ke olakino, ʻoi aku hoʻi i nā mea pono hale, nā mea kūkulu hale a me nā textiles.

 

Melamine Cyanurate Melamine Cyanurate

Hōʻike nui ʻia ka mīkini pale ahi o Melamine Cyanurate i kāna mau hiʻohiʻona decomposition i nā wela kiʻekiʻe a me ka hopena inhibitory o ka papa kalapona i hana ʻia ma ka hoʻolaha ʻana o ka lapalapa. Ma ke ʻano kikoʻī, hiki ke nānā ʻia ka hopena pale ahi o MCA mai nā ʻano aʻe:

(1) Hoʻokuʻu i ka nitrogen e kāohi i ka hāʻawi ʻana i ka oxygen

Loaʻa i nā molekala MCA ka nui o nā mea nitrogen. I ka wā o ka hoʻomehana ʻana, e hoʻokuʻu ʻia nā mea nitrogen e hana i ke kinoea (ka nui o ke kinoea nitrogen). ʻAʻole kākoʻo ke kinoea Nitrogen i ka puhi ʻana, no laila hiki iā ia ke hoʻoheheʻe maikaʻi i ka neʻe ʻana o ka oxygen a puni ke kumu ahi, e hoʻemi i ka mahana o ka lapalapa, a pēlā e hoʻolohi ai i ka nui o ka puhi ʻana a pale i ka laha ʻana o ke ahi. He mea koʻikoʻi kēia kaʻina hana i ka hoʻomaikaʻi ʻana i nā waiwai pale ahi o ka mea, ʻoi aku ma lalo o nā kūlana wela kiʻekiʻe.

(2) Hoʻoikaika i ka hoʻokumu ʻana i kahi papa carbonized

I ka wā o ke kaʻina hana pyrolysis, e hoʻoheheʻe ʻo MCA a hoʻohua i kahi papa kalapona i ka wā o ka decomposition thermal. ʻO kēia ʻāpana carbonized inert maikaʻi loa nā waiwai insulation thermal a hiki ke hana i ka pale ma waena o ka wahi i puhi ʻia a me ka wahi i puhi ʻole ʻia, e pale ana i ka hoʻoili ʻana o ka wela a hoʻopaʻa hou i ka laha ʻana o ka lapalapa.

Eia kekahi, hiki i ka papa carbonized ke hoʻokaʻawale i ka oxygen i ka lewa, e hana i kahi papa pale kino, e hōʻemi hou i ka pilina o ka oxygen me nā mea puhi ahi, a laila e pale pono i ka puhi ʻana. ʻO ka hoʻokumu ʻana a me ka paʻa ʻana o kēia papa kalapona ke kī inā hiki i ka MCA ke pāʻani pono i kahi hana ma ke ʻano he pale ahi.

(3) Hoʻopuka ka hopena kemika i ka mahu wai

Ma lalo o ke kaiapuni wela kiʻekiʻe, e loaʻa ana ʻo MCA i ka hopena decomposition a hoʻokuʻu i kekahi nui o ka mahu wai. Hiki i ka mahu wai ke hoemi pono i ka wela o ka aina a lawe aku i ka wela ma ka evaporation, pela e hooluolu ai i ke kumu ahi. Eia kekahi, hiki i ka hoʻokumu ʻana o ka mahu wai ke hōʻemi i ka neʻe ʻana o ka oxygen a puni ke kumu ahi, e pale hou aku i ka laha ʻana o ke ahi.

(4) ʻO ka hopena synergistic me nā mea hoʻohui ʻē aʻe

Ma waho aʻe o kāna hopena pale ahi ponoʻī, hiki i ka Melamine Cyanurate ke hui pū me nā mea pale ahi a i ʻole nā ​​​​mea hoʻopihapiha e hoʻomaikaʻi i nā waiwai pale ahi holoʻokoʻa o ka mea. No ka laʻana, hoʻohana pinepine ʻia ʻo MCA me ka phosphorus flame retardants, inorganic fillers, etc., hiki ke hoʻomaikaʻi i ka paʻa wela a me nā waiwai mechanical o ka mea a hoʻoikaika i ka hopena o ka lapalapa ahi.

 

ʻO nā pono a me nā noi o ka Melamine Cyanurate

(1) Pili kaiapuni a ʻaʻohe mea ʻawaʻawa

Ke hoʻohālikelike ʻia me nā mea hoʻopaʻa ahi halogen kuʻuna, ʻaʻole hoʻokuʻu ʻo MCA i nā kinoea halogen pōʻino (e like me ka hydrogen chloride, hydrogen bromide, a me nā mea ʻē aʻe) i ka wā o ke kaʻina hana pale ahi, e hōʻemi ana i ka pollution i ke kaiapuni a me ka pōʻino i ke olakino kanaka. ʻO ke kaʻina hana hoʻokuʻu nitrogen o MCA he palekana, no laila, ʻoi aku ka maikaʻi o ke kaiapuni i ka wā o ka hoʻohana ʻana a me ka liʻiliʻi o ka hopena i ke kaiaola.

(2) Paʻa wela maikaʻi a kūʻē i ka wā

Loaʻa i ka MCA ke kūpaʻa wela kiʻekiʻe, hiki ke mālama i nā waiwai kemika paʻa i nā wela kiʻekiʻe, a pale pono i ka puhi ʻia e nā wela kiʻekiʻe. Ma kekahi mau kaiapuni hana wela, hiki i ka MCA ke hāʻawi i ka pale mau loa ma ke ʻano he pale ahi.

Eia hou, ua ikaika ka MCA i ke kū'ē i ka wā, hiki ke mālama i ka hana maikaʻi i ka hoʻohana lōʻihi, a hoʻololi i nā kūlana climatic like ʻole.

(3) Uahi haʻahaʻa

Hoʻemi ʻo MCA i ka uahi ke hoʻomehana ʻia i nā wela kiʻekiʻe. Ke hoʻohālikelike ʻia me nā mea pale ahi halogen kuʻuna, hiki iā ia ke hōʻemi nui i ka hoʻokuʻu ʻana i nā kinoea ʻona i ke ahi a hōʻemi i ka pōʻino o ka uahi i nā limahana.

 

Ma keʻano he mea pili i ke kaiapuni a me ka meaʻawaʻawaʻolepale ahi, Loa'a iā Melamine Cyanurate kahi mīkini pale ahi kū'oko'a e hō'ike ana i kahi ākea o nā mana'o noi i nā mea hou. Me ka hoʻomau mau ʻana o ka mālama ʻana i ke kaiapuni a me nā koi palekana, e hoʻohana ʻia ʻo Melamine Cyanurate i nā kula hou aʻe a lilo i hoʻokahi o nā mea nui o nā mea pale ahi.

 

No ka ʻike hou aku e pili ana i ke koho ʻana i kahi MCA kūpono iā ʻoe, e ʻoluʻolu e nānā i kaʻu ʻatikala "Pehea e koho ai i ka melamine cyanurate maikaʻi?"Manaʻolana wau e kōkua ia iā ʻoe.
