Magani na Tsare-tsare don Rage Girman Fim na TPU (Yanzu: 280; Manufar: <200)
(Tsarin na yanzu: Aluminum hypophosphite 15 phr, MCA 5 phr, Zinc borate 2 phr)

I. Mahimman Bayanan Mahimmanci

1. Iyakance Tsarin Halitta na Yanzu:

• Aluminum hypophosphite: Da farko yana hana yaduwar harshen wuta amma yana da iyakacin hana hayaki.
• MCA: Ƙarƙashin harshen wuta na lokaci-lokaci mai tasiri ga afterglow (wanda ya riga ya hadu da manufa) amma bai isa ba don rage yawan hayaki.
• Zinc borate: Yana haɓaka ƙirƙira char amma ba'a yin amfani da shi (2 phr kawai), ya kasa samar da isasshen adadin char ɗin da zai kashe hayaki.

1. Mabuɗin Bukata:

• Rage yawan hayakin konewa ta hanyarchar-enhanaman hayaki kashewakohanyoyin dilution gas-lokaci.

II. Dabarun ingantawa

1. Daidaita Ragowar Ƙirƙirar Ƙirƙirar Ƙirƙiri

• Aluminum hypophosphite: Ƙara zuwa18-20 ph(yana haɓaka jinkirin yanayin zafi mai raɗaɗi; lura da sassauci).
• MCA: Ƙara zuwa6-8 ph(yana haɓaka aikin-lokacin iskar gas; adadin da ya wuce kima na iya lalata aiki).
• Zinc borate: Ƙara zuwa3-4 ph(yana ƙarfafa samuwar char).

Misali Daidaita Tsarin:

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

2. Gabatar da Maganganun Maganin Tabar Sigari

• Molybdenum mahadi(misali, zinc molybdate ko ammonium molybdate):
• Matsayi: Yana hana samuwar char, yana haifar da shinge mai yawa don toshe hayaki.
• Sashi: 2-3 phr (yana aiki tare da zinc borate).
• Nanoclay (montmorillonite):
• Matsayi: Shamaki na jiki don rage sakin iskar gas mai ƙonewa.
• Sashi: 3-5 phr (wanda aka gyara saman don watsawa).
• Silicone-tushen harshen wuta retardants:
• Matsayi: Yana inganta ingancin char da kashe hayaki.
• Sashi: 1-2 phr (yana guje wa asarar bayyana gaskiya).

3. Haɓaka Tsarin Haɗin kai

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

III. Shawarar Ƙirƙirar Ƙirƙiri

Sakamakon da ake tsammani:

• Yawan konewa: ≤200 (ta hanyar char + gas-lokaci daidaitawa).
• Yawan hayaki mai haske: Kula da ≤200 (MCA + zinc borate).

IV. Bayanan Haɓaka Maɓalli

1. Tsarin Zazzabi: Kula da 180-200 ° C don hana bazuwar harshen wuta da wuri.
2. Watsewa:

• Yi amfani da haɗe-haɗe mai sauri (≥2000 rpm) don rarraba nanoclay/molybdate iri ɗaya.
• Ƙara 0.5-1 phr silane coupling agent (misali, KH550) don inganta daidaitawar filler.

1. Samuwar Fim: Don yin simintin gyare-gyare, rage yawan sanyaya don sauƙaƙe samuwar char Layer.

V. Matakan Tabbatarwa

1. Gwajin Lab: Shirya samfurori ta hanyar da aka ba da shawarar; gudanar da UL94 a tsaye ƙonawa da gwajin yawan hayaki (ASTM E662).
2. Daidaiton Ayyuka: Gwada ƙarfin ƙarfi, elongation, da bayyana gaskiya.
3. Haɓaka juzu'i: Idan yawan hayaki ya kasance babba, ƙara daidaita molybdate ko nanoclay (± 1 phr).

VI. Farashin & Yiwuwa

• Tasirin farashi: Zinc molybdate (~¥ 50/kg) + nanoclay (~¥30/kg) yana ƙara yawan farashi da <15% a ≤10% lodi.
• Ƙimar Masana'antu: Mai jituwa tare da daidaitaccen aiki na TPU; babu kayan aiki na musamman da ake buƙata.

VII. Kammalawa

Byƙara zinc borate + ƙara molybdate + nanoclay, tsarin aiki sau uku (samuwar chaji + dilution gas + shingen jiki) zai iya cimma maƙasudin yawan hayaki mai ƙonewa (≤200). Bada fifikon gwajimolybdate + nanoclayhade, sa'an nan lafiya-tune rabo ga kudin-yi ma'auni.
