Daga Mahangar Sinadarin Triazine: Dalilin Da Ya Sa Masu Hana Wutar Lantarki Masu Tushen Nitrogen Suka Fi Son Triazine
Mutane da yawa suna da tambaya lokacin da suka fara hulɗa da masu hana harshen wuta masu ɗauke da nitrogen:
Tunda rage wutar lantarki yana buƙatar "nitrogen", me yasa masana'antar a ƙarshe ta zaɓi tsarin "zoben triazine", maimakon mafi sauƙi na amines, urea, gishirin guanidine, ko ma amide na yau da kullun?
Da ace kawai manufar ita ce a saki iskar nitrogen, a ka'ida, tsarin da ke ɗauke da nitrogen da yawa zai iya cimma wannan.
Amma ainihin matsalar ita ce:
Rashin fitar da hayaki daga wuta ba abu ne mai sauƙi ba kamar "sakin wasu iskar gas". Madadin haka, yana buƙatar ci gaba da daidaita kwararar kuzarin kayan, free radicals, tsarin char layer, da hanyoyin lalata zafi a yanayin zafi mai yawa.
Zoben triazine yana ɗaya daga cikin ƙalilan da aka sani waɗanda ke ɗauke da sinadarin nitrogen waɗanda za su iya cika waɗannan hanyoyi guda biyar a lokaci guda:
Yawan nitrogen Mai Girma Tsayin daka Mai Kyau Tsarin zafi Mai sarrafawa Rushewar endothermic a cikin situ polycondensation da tsarin cibiyar sadarwa Tasirin haɗin gwiwa mai zurfi tare da tsarin phosphorus
Shi ya sa, daga melamine na gargajiya, zuwa MPP, MCA, CFA, DOPO-triazine, har zuwa tsarin IFR na zamani mara halogen, kusan duk ba za a iya raba su da "sinadarin triazine" ba.
01 Asalin Matsalar: Dalilin da yasa Tsarin da ke ɗauke da Nitrogen na yau da kullun ba su da isasshe
Da farko, bari mu dubi wasu sifofi masu dauke da sinadarin nitrogen:
Bambancin gaske yana cikin ko tsarin kwayoyin halitta zai iya "tsira" tagar zafin da polymer ke fitarwa don "aiki" bayan fallasa shi ga yanayin zafi mai yawa.
Yawancin gine-gine masu dauke da sinadarin nitrogen suna ruɓewa gaba ɗaya kuma suna yin volatili a zafin 250–320°C. Amma zoben triazine ba ya yin hakan.
02 Me Ya Sa Zoben Triazine Yake da Muhimmanci Gare Mu: Ba Kawai Yana Da Muhimmanci Ba
"Rabuwa" - "Polycondenses"
Zoben triazine (1,3,5-triazine) zobe ne mai ƙumshi mai mambobi shida na CN wanda ba shi da sinadarin electron sosai.
03 Babban Ikon Masu Hana Wutar Lantarki na Triazine: "NC Network"
Fahimtar mutane da yawa game da jinkirin harshen melamine ya tsaya ne kawai a:
"Sakin NH₃ don rage iskar oxygen"
A gaskiya ma, wannan ya bayyana ƙaramin ɓangare ne kawai.
Abin da ke tabbatar da ingancin hana ƙonewa shine sinadaran da ke biyo baya na lokaci mai rikitarwa.
Mataki na 1: Shakar zafi + sakin iskar gas mara aiki
Melamine yana fara yin kyau kuma yana ruɓewa a kusan 320-350°C:
Zafin da ke ɓoye na sublimation: kimanin 120 kJ/mol
Jimlar shan zafi yayin pyrolysis: kusan 2000 kJ/mol
A halin yanzu, yana fitar da ➡︎ NH₃, N₂, da kuma ƙaramin adadin gutsuttsuran cyano...
Waɗannan iskar gas suna aiki don rage iskar oxygen, rage gurɓatattun abubuwa masu ƙonewa, da rage zafin wuta...
Wannan ita ce sanannen hanyar hana harshen wuta ta hanyar amfani da iskar gas. Duk da haka, wannan ba shine mafi mahimmancin mataki ba.
Mataki na 2: Polycondensation don samar da "hanyar sadarwa ta carbon nitride"
Tsarin triazine bai lalace gaba ɗaya ba. Madadin haka, yana ƙara fuskantar ➡︎ deamination, polycondensation, aromatization, da kuma haɗin kai mai layi.
A ƙarshe yana samar da tsarin carbon nitride mai ƙarfi wanda yayi kama da graphitic carbon nitride (g-C₃N₄).
Nufin wannan:
✅ Ana samar da wani yanki mai cike da sinadarin nitrogen, mai ɗauke da ƙamshi mai yawa, mai yawan haɗakar launuka masu yawa, mai kuma yawan haɗuwa a saman kayan.
04 Me yasa Triazine Char Layer yake da ƙarfi sosai?
An samar da Char ta hanyar polyolefins na yau da kullun: sassauƙa kuma mai sauƙin fashewa
Amma layin char da tsarin triazine ya samar:
Saboda haka, abin da tsarin IFR da yawa masu ɗauke da triazine suka inganta ba shine "ba a iya ƙonewa ba", amma pHRR (ƙayyadadden lokacin fitar da zafi).
Yana ɗaya daga cikin mahimman sigogi a cikin ma'aunin kalori na mazugi. Wannan fasalin zai iya samo nau'ikan samfuran daban-daban masu hana harshen wuta!!
05 Me yasa ake amfani da Triazine da Phosphorus a hade?
Domin su biyun suna da alaƙa ta halitta:
Menene alhakin triazine? Yana da alhakin shaƙar zafi, fitar da iskar gas, ƙirƙirar hanyar sadarwa da inganta ƙarfin layin char.
Menene sinadarin phosphorus ke da alhakinsa? Yana da alhakin bushewar iskar oxygen, samuwar sinadarai masu guba da kuma rage kuzarin kunna pyrolysis.
Saboda haka, "Haɗin kai na PN" ya zama babban hanyar masu hana harshen wuta na zamani marasa halogen.
06 Me yasa MPP ta fi MP ƙarfi?
Wannan wata dabara ce ta "tsarin ƙira ta triazine".
MP (Melamine Phosphate)
Sinadaran: Melamine + Phosphoric acid
Yawan sinadarin Char residue (700°C): kimanin kashi 30%
MPP (Melamine Polyphosphate)
Tsarin: Cibiyar sadarwa ta PN tare da babban matakin polymerization
Halaye: raguwar phosphorus a hankali + tsawon lokaci na tushen acid + ƙarin isasshen yawan tururin triazine
Saboda haka, yawan sinadarin char da ke fitowa a zafin 700°C zai iya kaiwa kusan kashi 40%. Wannan ƙimar ta riga ta yi yawa sosai ga tsarin halitta.
Musamman a cikin PA, PBT da TPEE, ƙimar MPP ba wai kawai tana bayyana a cikin aikin UL94 ba, har ma a cikin:
Rage diga ruwa
Ƙarfafa layin char
Inganta daidaiton GWIT/GWFI
07 Me yasa Ingancin Tsarin DOPO-Triazine Ya Yi Kyau Sosai?
Domin kuwa yana cimma haɗin gwiwa na hana iskar gas da kuma samar da hanyar sadarwa mai tsari a karon farko.
DOPO na Gargajiya: ƙarfin aiki mai ƙarfi na lokacin gas, duk da haka:
Layin char bai yi tsauri sosai ba
Mai saurin kamuwa da ƙonewa a matakin ƙarshe na ƙonewa
Triazin gargajiya: kyakkyawan aikin char Layer, duk da haka:
Iyakanceccen ikon kama ƙwayoyin cuta masu guba
Saboda haka, masu bincike sun tsara wani tsari mai suna triazine a matsayin kwarangwal na tsakiya, wanda hakan ya ƙara dasa shi:
DOPO
Phosphite
Fosfonate
Benzimidazole
don samar da "mai hana harshen wuta mai aiki biyu".
08 Me yasa Triazine Kusan Yake Mamaye Ba Tare Da Halogen Ba
Masu hana harshen wuta daga sinadarin Nitrogen?
Domin yana magance matsaloli guda huɗu a lokaci guda:
Mafi mahimmanci, ba ya dogara da tsari ɗaya tilo ba. Madadin haka, tsari ne mai ci gaba da "ci gaba" na amsawar zafin jiki mai zafi.
09 Babban Mahimmin Bayani: Triazine Ba wai kawai "Ƙari" ba ne, amma "Ƙwayar Thermochemical"
Fahimtar yawancin mutane game da na'urorin rage harshen wuta har yanzu tana nan ne kawai a kan "ƙara nau'in na'urar rage harshen wuta guda ɗaya".
Duk da haka, ƙwararrun ƙwararru ba sa ƙara tsara dabarun hana harshen wuta ta wannan hanyar.
Ainihin, ƙirar mai hana harshen wuta mai ƙarfi shine ƙirar:
Hanyar Pyrolysis
Sinadarin Char Layer
Shige da fice kyauta
Yanayin wargaza makamashi
Mafi girman darajar zoben triazine yana cikin tsarin "tsarin hanyar sadarwa mai ƙamshi mai ƙarfi ta nitrogen-carbon".
Idan kuna cikin haɓaka fannoni masu zuwa:
Gyaran hana harshen wuta na PA / PBT / PET / PC
Ƙimar UL94 V0 / 5VA mara halogen
Aikin GWIT / CTI / Wayar Haske
Nailan mai zafin jiki mai yawa
Tsarin hana harshen wuta mara PFAS
Kayan lantarki da kayan lantarki masu sirara
Za ku fahimci cewa ƙalubalen da yawa na ƙirƙirar tsari a ƙarshe ba ya dogara ne akan dabarar kanta ba, amma akan fahimtar tsarin hana ƙonewa.
