Rongoa Nahanaha mo te Whakaiti i te Totote Paoa Kiriata TPU

Rongoa Nahanaha mo te Whakaititia TPU Kiriata Auahi Kiato (Naianei: 280; Whainga: <200)
(Te hanga o naianei: Aluminium hypophosphite 15 phr, MCA 5 phr, Zinc borate 2 phr)

I. Tirohanga Take Matua

1. Te herenga o te whakatakotoranga o naianei:

• Konumohe hypophosphite: Ko te tuatahi ka pehi i te mura o te ahi engari he iti te pehi auahi.
• MCA: He parenga mura-hau e whai hua ana mo te mura o muri (kua tutuki i te whaainga) engari he iti rawa mo te whakaheke i te auahi.
• Zinc borate: Ka whakatairanga i te hanga waro engari ka iti te horopeta (e 2 haora anake), karekau i te hanga i te paparanga wao kia pehia te auahi.

1. Whakaritenga Matua:

• Whakaitihia te kiato paowa ngingiha mate whakakore i te auahi kua whakanuiaraneihau-waahanga tikanga dilution.

II. Rautaki Arotautanga

1. Whakaritea nga Tauwehenga Whakaritenga Tiariari

• Konumohe hypophosphite: Whakanuia ki18–20 ph(whakarei ake i te whakamaaramatanga o te mura o te ahi; te ngawari ki te aroturuki).
• MCA: Whakanuia ki6–8 ph(ka whakanui i te mahi hau-waahanga; te nui rawa o te moni ka heke te tukatuka).
• Zinc borate: Whakanuia ki3–4 ph(whakakaha ana i te hanga waro).

Tauira Whakaritea Whakaritenga:

• Konumohe hypophosphite: 18 phr
• MCA: 7 phr
• Zinc borate: 4 phr

2. Whakauruhia nga Kaipupuri Paoa Tino Tino

• Pūhui Molybdenum(hei tauira, zinc molybdate, ammonium molybdate ranei):
• Tūnga: Ka whakakorikori i te hanga waro, ka hangaia he arai matotoru hei aukati i te auahi.
• Inenga: 2–3 phr (ka mahi tahi me te zinc borate).
• Nanoclay (montmorillonite):
• Tūnga: Arai tinana hei whakaiti i te tuku hau mura.
• Inenga: 3–5 phr (whakarereke-mata mo te marara).
• Ko nga mea whakaahuru-a-huru-a-huru:
• Tūnga: Ka whakapai ake i te kounga o te char me te aukati auahi.
• Inenga: 1–2 phr (ka karo i te ngaronga marama).

3. Synergistic System Optimization

• Zinc borate: Taapirihia te 1–2 haora ki te whakakotahi ki te konumohe hypophosphite me te zinc borate.
• Amonium polyphosphate (APP): Taapirihia te 1–2 haora hei whakarei ake i te mahi hau-waa me MCA.

III. Whakatairanga Matawhānui Manakohia

Hua e tumanakohia ana:

• Te kiato o te auahi: ≤200 (ma te char + hau-waa mahi tahi).
• Kiato auahi o muri: Kia mau ki te ≤200 (MCA + zinc borate).

IV. Nga Panui Arotautanga Tukatuka Matua

1. Te Waahi Tukatuka: Kia mau ki te 180–200°C hei aukati i te pirau o te mura ahi.
2. Marara:

• Whakamahia te whakaranu tere (≥2000 rpm) mo te tohatoha nanoclay/molybdate.
• Tāpirihia he kaihoko hono 0.5–1 phr silane (hei tauira, KH550) hei whakapai ake i te hototahi whakakii.

1. Te Hanga Kiriata: Mo te makanga, whakaitihia te tere whakamahana kia pai ai te hanga paparanga.

V. Nga Tikanga Whakamana

1. Whakamatau Taiwhanga: Whakaritehia nga tauira mo ia hanganga e taunakitia ana; whakahaere UL94 tahu poutū me nga whakamatautau kiato auahi (ASTM E662).
2. Taurite Mahinga: Whakamatauhia te kaha o te kaha, te whakaroa, me te marama.
3. Arotautanga Tukurua: Ki te nui tonu te kiato auahi, whakatikahia te molybdate me te nanoclay (±1 phr).

VI. Te Utu me te Mahinga

• Paanga Utu: Zinc molybdate (~¥50/kg) + nanoclay (~¥30/kg) te whakanui ake i te utu katoa ma te <15% i te ≤10% te utaina.
• Te Whakanui Ahumahi: Hototahi ki te tukatuka TPU paerewa; kaore he taputapu motuhake e hiahiatia ana.

VII. Whakamutunga

Nate whakanui ake i te zinc borate + te taapiri molybdate + nanoclay, he punaha mahi-toru (hanga waro + waimeha hau + arai tinana) ka taea te whakatutuki i te kiato o te paowa ngingiha (≤200). Te tuatahi ki te whakamatautau i temolybdate + nanoclayte whakakotahitanga, katahi ka whakatika pai mo te toenga utu-mahi.
