Mai i te Tirohanga o te Matū Triazine: He aha i Pai ake ai ngā Ārai Mumura e Hangai Ana ki te Hauota ki te Triazine
He pātai ā te tini tāngata ina tūtaki tuatahi rātou ki ngā mea ārai mura kei roto he hauota:
I te mea me "hauota" te ātete mura, he aha te take i whiriwhiri nui ai te umanga i te hanganga "mowhiti triazine", kaua ki ngā amine māmā ake, te urea, te tote guanidine, tae atu ki ngā amide noa?
Mehemea ko te tukunga o te hau hauota anake te whāinga, e ai ki te ariā he maha ngā hanganga kei roto he hauota ka taea tēnei te whakatutuki.
Engari ko te take tūturu:
Ehara i te mea ngāwari te aukati mura pērā i te "tukunga o ētahi hau". Engari, me whakahaere tonu te rere o te pūngao o te rauemi, ngā rauropi kore utu, te hanganga o te paparanga waro, me ngā ara pirau wera i ngā pāmahana tiketike.
Ko te mowhiti triazine tētahi o ngā hanganga torutoru e mōhiotia ana kei roto he hauota ka taea te whakatutuki i ngā tikanga e rima e whai ake nei i te wā kotahi:
Te nui o te hauota Te pumau wera Te pirau wera-whakahaere Te polycondensation in-situ me te hanganga whatunga Te pānga hohonu o te mahi tahi me ngā pūnaha phosphorus
Koia te take, mai i te melamine tuku iho, ki te MPP, MCA, CFA, DOPO-triazine, tae atu ki ngā pūnaha IFR kore-halogen hou, tata katoa e kore e taea te wehe i te "matū triazine".
01 Te Kaupapa o te Raru: He aha i kore ai e pai ngā hanganga noa kei roto te hauota
Tuatahi, me titiro tātou ki ētahi hanganga noa kei roto he hauota:
Ko te rerekētanga tūturu kei roto i te kaha o te hanganga ngota "ki te ora" i te matapihi pāmahana pirau o te pūmua kia "mahi" ai i muri i te pānga ki te pāmahana teitei.
He maha ngā hanganga noa kei roto he hauota ka pirau katoa, ka memeha haere i te 250–320°C. Engari kāore te mowhiti triazine e pirau.
02 He aha te mea e tino motuhake ai te mowhiti Triazine: Ehara i te mea he mea motuhake noa iho
"Ka pirau" — Ka "Poropūpū"
Ko te mowhiti triazine (1,3,5-triazine) he mowhiti kakara CN ono-mema, he iti rawa te irahiko.
03 Te Pūkenga Matua o ngā Ārai Mura Triazine: "Whatunga NC"
Ko te māramatanga o te tini o te tangata mō te ātete mura o te melamine e noho ana i:
"Te tuku i te NH₃ hei whakamāeneene i te hāora"
Ina hoki, he wāhanga iti noa iho tēnei e whakamārama ana.
Ko te matū o te wāhanga whakakōpiri e whai ake nei e whakatau ana i te whai huatanga o te aukati mura.
Wāhanga 1: Te mimiti wera + te tukunga o te hau kore mahi
Ka tīmata te memeha haere o te melamine i te pāmahana tata ki te 320–350°C:
Te wera huna o te whakapūmautanga: tata ki te 120 kJ/mol
Te mimiti wera katoa i te wā o te whakapūkara: tata ki te 2000 kJ/mol
I taua wā tonu, ka tukuna e ia ➡︎ NH₃, N₂, me tētahi wāhanga iti o ngā maramara cyano...
Ko te mahi a ēnei hau he ➡︎ whakawaiwai i te hāora, he whakawaiwai i ngā mea mura, he whakaiti hoki i te pāmahana o te mura...
Koinei te tikanga ārai mura hau-āhua rongonui. Heoi, ehara tēnei i te taahiraa tino nui.
Wāhanga 2: Te whakapūngao-maha hei hanga i tētahi "whatunga waro hauota"
Kāore te hanganga triazine e pakaru katoa. Engari, ka pāngia anō e te ➡︎ deamination, polycondensation, aromatization, me te crosslinking paparanga.
Ka puta he hanganga waro nitride tino pumau, he rite ki te waro nitride graphitic (g-C₃N₄).
Ko te tikanga tēnei:
✅ Ka hangaia he paparanga waro honohono-rahi, whai rawa i te hauota, whai mowhiti kakara, ki runga i te mata o te rauemi.
04 He aha te kaha rawa o te paparanga waro Triazine?
Te waro i hangaia e ngā polyolefin noa: he marara, he ngāwari hoki te pakaru
Engari ko te paparanga waro i hangaia e te pūnaha triazine:
Nō reira, ko te mea e tino whakapai ake ana i roto i ngā pūnaha IFR kei roto i te triazine, ehara i te "kore e mura", engari ko te pHRR (te tere tuku wera tino nui).
Ko tētahi o ngā tawhā tino hira o te ine kaha o te koni. Ka taea e tēnei āhuatanga te whakaputa i te whānuitanga o ngā hua ārai mura rerekē!!
05 He aha i whakamahia ngātahi ai te Triazine me te Phosphorus?
Nā te mea he mea tautoko ā-tūturu ngā mea e rua:
He aha te mahi a te triazine? Koia te kawenga mō te mimiti wera, te tuku hau, te hanganga whatunga me te whakapai ake i te kaha o te paparanga waro.
He aha te mahi a te whākōkī? Koia te take o te maroketanga o te matū, te hanganga waro matatau, me te whakaiti i te kaha whakahohe o te pyrolysis.
Nō reira, kua riro te "PN synergy" hei huarahi matua mō ngā aukati mura kore-halogen hou.
06 He aha i kaha ake ai te MPP i te MP?
He "arorau hoahoa triazine" tino noa tēnei.
MP (Melamine Phosphate)
Te uho: Melamine + Waikawa Phosphoric
Te hua o te toenga waro (700°C): tata ki te 30%
MPP (Melamine Polyphosphate)
Hanganga: Whatunga PN me te taumata teitei ake o te polymerization
Ngā Āhuatanga: te puhoi o te whakapūngao o te phosphorus + te roa o te pūtake waikawa + te nui ake o te whakapūngao triazine
Nō reira, ka taea e te putanga o ngā toenga waro i te 700°C te eke ki te 40%. He tino teitei kē tēnei uara mō ngā pūnaha rauropi.
Ina koa i roto i te PA, PBT me te TPEE, ko te uara matua o te MPP ehara i te mea ka kitea noa i roto i te mahi UL94, engari i roto hoki i:
Te whakaiti i te maturuturu
Te whakapakari i te paparanga waro
Te whakapai ake i te pumau o te GWIT/GWFI
07 He aha te Tino Hiranga o te Whai Huatanga o te Pūnaha DOPO-Triazine?
Nā te mea ka tutuki i a ia te hononga honohono o te aukati irahiko hau-wāhanga me te hanganga whatunga wāhanga-whakapoto mō te wā tuatahi.
DOPO tuku iho: te kaha o te mahi hau-āhuatanga, heoi anō:
Kāore i te tino pakari te paparanga waro
Ka pāngia e te wera i te wāhanga whakamutunga o te tahunga
Triazine tuku iho: he tino pai te mahi a te paparanga āhua, engari:
He iti te kaha ki te hopu i ngā rauropi kore utu
Nō reira, i hangaia e ngā kairangahau tētahi hanganga me te triazine hei angaanga matua, me te tāpiri atu anō:
DOPO
Phosphite
Phosphonate
Benzimidazole
hei hanga i tētahi "ārai mura ahunga-rua mahi".
08 He aha te Triazine e tata ana ki te whakahaere i te kore-halogen
Ngā Ārai Mura e Hangai Ana ki te Hauota?
Nā te mea e whakaoti ana i ngā raruraru e whā i te wā kotahi:
Ko te mea nui ake, kāore e whakawhirinaki ki tētahi tikanga kotahi. Engari, he tukanga tauhohenga pāmahana teitei e "whakawhanake tonu" ana.
09 Te Kaupapa Matua Tuturu: Ehara te Triazine i te "Tāpiritanga" noa iho, engari he "Angaanga Matū Matū"
Ko te nuinga o te iwi e mōhio ana ki ngā ārai mura e noho tonu ana ki te "tāpiri noa i tētahi momo ārai mura".
Heoi anō, kāore ngā tohunga mātau e hoahoa ana i ngā hanganga ārai mura pēnei.
Ko te hoahoa ātete mura taumata teitei ko te hoahoa o:
Ara whakapūkara
Te matū o te paparanga waro
Te hekenga o ngā rauropi kore utu
Aratau whakamararatanga pūngao
Ko te uara nui rawa atu o te mowhiti triazine kei roto i tōna hanganga "whatunga hauota-waro kakara pumau".
Mena kei te whai wāhi koe ki te whakawhanake i ngā mara e whai ake nei:
Te whakarerekētanga ātete mura o te PA / PBT / PET / PC
Whakatauranga UL94 V0 / 5VA kore-halogen
Mahi GWIT / CTI / Waea kanapa
Nairona pāmahana teitei
Ngā pūnaha ārai mura kore-PFAS
Ngā rauemi hiko me ngā rauemi hikohiko angiangi
Ka mārama koe ko te nuinga o ngā wero o te hanga ehara i te mea e whakawhirinaki ana ki te hanga tonu, engari ki te māramatanga hōhonu o te hanganga ātete mura.
