Maganin Tsari don Rage Yawan Hayaki na Fim na TPU

Maganin Tsari don Rage Yawan Hayaki na Fim na TPU (Yanzu: 280; Manufofi: <200)
(Tsarin da ake amfani da shi a yanzu: Aluminum hypophosphite 15 phr, MCA 5 phr, Zinc borate 2 phr)

I. Binciken Matsalolin Muhimmi

1. Iyakokin Tsarin Yanzu:

• Aluminum hypophosphite: A takaice dai yana hana yaɗuwar harshen wuta amma yana da ƙarancin hana hayaƙi.
• MCA: Wani abu mai hana harshen wuta na iskar gas wanda ke da tasiri ga hasken bayan an yi amfani da shi (wanda ya riga ya cika abin da ake so) amma bai isa ba don rage hayakin konewa.
• Zinc borate: Yana haɓaka samuwar char amma ba a shansa sosai (sau 2 kawai), ba tare da samar da isasshen char Layer don kashe hayaki ba.

1. Babban Bukatu:

• Rage yawan hayakin konewa ta hanyarrage hayaki mai ƙarfikohanyoyin narkewar iskar gas.

II. Dabaru na Ingantawa

1. Daidaita Rabon Tsarin da ke Akwai

• Aluminum hypophosphite: Ƙara zuwa18–20 ph(yana inganta jinkirin harshen wuta; yana sa ido kan sassauci).
• MCA: Ƙara zuwa6–8 phr(yana haɓaka aikin matakin iskar gas; yawan da ya wuce kima na iya lalata aikin).
• Zinc borate: Ƙara zuwa3–4 phr(yana ƙarfafa samuwar char).

Misalin Tsarin da aka Gyara:

• Aluminum hypophosphite: 18 hr
• MCA: 7 phr
• Zinc borate: 4 hr

2. Gabatar da Magungunan rage hayaki masu inganci

• Magungunan Molybdenum(misali, zinc molybdate ko ammonium molybdate):
• Matsayin: Yana haɓaka samuwar char, yana ƙirƙirar shinge mai yawa don toshe hayaki.
• Yawan amfani: 2-3 phr (yana haɗuwa da zinc borate).
• Nanoclay (montmorillonite):
• Matsayin: Katanga ta zahiri don rage fitar iskar gas mai ƙonewa.
• Yawan amfani: 3-5 phr (an gyara saman don watsawa).
• Masu hana harshen wuta bisa silicone:
• Matsayin: Yana inganta ingancin wuta da kuma rage hayaki.
• Yawan amfani: 1-2 phr (yana guje wa asarar bayyananniya).

3. Inganta Tsarin Haɗin Kai

• Zinc borate: Ƙara 1-2 phr don haɗa shi da aluminum hypophosphite da zinc borate.
• Ammonium polyphosphate (APP): Ƙara 1-2 phr don haɓaka aikin gas-phase tare da MCA.

III. Cikakken Tsarin da aka Ba da Shawara

Sakamakon da ake tsammani:

• Yawan hayakin da ke ƙonewa: ≤200 (ta hanyar haɗin gwiwa tsakanin char + gas-phase).
• Yawan hayakin bayan haske: Kula da ≤200 (MCA + zinc borate).

IV. Muhimman Bayanan Inganta Tsarin Aiki

1. Zafin Aiki: A ajiye a zafin jiki na 180–200°C domin hana rugujewar mai hana harshen wuta da wuri.
2. Watsawa:

• Yi amfani da haɗakarwa mai sauri (≥2000 rpm) don rarrabawar nanoclay/molybdate iri ɗaya.
• Ƙara wakilin haɗin silane na 0.5–1 (misali, KH550) don inganta dacewa da cikawa.

1. Tsarin Fim: Don yin siminti, rage saurin sanyaya don sauƙaƙe samuwar layukan char.

V. Matakan Tabbatarwa

1. Gwajin Lab: Shirya samfura bisa ga shawarar da aka bayar; gudanar da gwaje-gwajen ƙonawa a tsaye da yawan hayaki na UL94 (ASTM E662).
2. Daidaiton Aiki: Gwada ƙarfin juriya, tsawaitawa, da kuma bayyana gaskiya.
3. Ingantawa akai-akai: Idan yawan hayaki ya ci gaba da ƙaruwa, a hankali a daidaita molybdate ko nanoclay (±1 phr).

VI. Farashi & Sauƙin Amfani

• Tasirin Farashi: Zinc molybdate (~¥50/kg) + nanoclay (~¥30/kg) ya ƙara jimillar farashi da <15% a ≤10% na lodi.
• Ma'aunin Masana'antu: Ya dace da tsarin sarrafa TPU na yau da kullun; babu buƙatar kayan aiki na musamman.

VII. Kammalawa

Ta hanyarƙara yawan zinc borate + ƙara molybdate + nanoclay, tsarin aiki uku (samuwar char + narkewar iskar gas + shingen zahiri) zai iya cimma yawan hayakin konewa da ake so (≤200). A ba da fifiko ga gwajinmolybdate + nanoclayhaɗuwa, sannan daidaita rabon don daidaita farashi da aikin.
