Tsarin Mahimman Bayanai na PP V2 Mai Rage Wutar Lantarki
Domin cimma nasarar rage harshen wuta ta UL94 V2 a cikin manyan batches na PP (polypropylene), ana buƙatar haɗakar masu rage harshen wuta tare da kiyaye aikin sarrafawa da halayen injiniya. Ga shawarwarin da aka inganta tare da bayani:
I. Shawarar Tsarin Tushe
Tsarin Maganin Rage Wuta:
| Bangaren | Ana lodawa (wt%) | Bayanin Aiki |
| PP Resin | Kashi 50-60% | Resin mai ɗaukar kaya (ana ba da shawarar ma'aunin kwararar narkewa mai ƙarfi, misali, MFI 20-30 g/minti 10) |
| Aluminum Hypophosphite | Kashi 15-20% | Tushen acid, yana haɓaka samuwar char, kwanciyar hankali mai kyau na thermal don sarrafa PP |
| Zinc Borate | 5-8% | Maganin hana harshen wuta mai haɗin gwiwa, yana hana hayaki kuma yana ƙara juriyar harshen wuta a lokacin iskar gas |
| Aluminum Hydroxide da aka Gyara a Sama | Kashi 10-15% | Rushewar endothermic, yana rage zafin konewa (maganin saman, misali, wakilin haɗin silane, an ba da shawarar) |
| Dipentaerythritol (Di-PE) | 5-8% | Tushen carbon, yana haɗuwa da tushen acid don samar da char mai ƙarfi |
| Melamine Polyphosphate (MPP) | Kashi 3-5% | Tushen iskar gas (ƙarin da aka ba da shawarar), yana fitar da iskar gas mara aiki don haɓaka ƙarfin iska |
| Maganin hana digawa (PTFE) | 0.3-0.5% | Yana rage digowar narkewa (zaɓi ne ga V2, kamar yadda aka yarda da digowar) |
| Maganin hana tsufa (1010/168) | 0.3-0.5% | Yana hana lalacewar yanayin zafi yayin sarrafawa |
| Man shafawa (Zinc Stearate) | 0.5-1% | Inganta kwararar aiki da watsawa |
| Mai ɗaukar Launi & Launi | Kamar yadda ake buƙata | Zaɓi launuka masu jure zafi mai yawa don guje wa amsawa tare da abubuwan hana harshen wuta |
II. Muhimman Mahimman ...
- Tsarin Hana Wuta Mai Haɗaka
- Ƙunƙarar Harshen Harshen Wuta (IFR):Aluminum hypophosphite (tushen acid) + Di-PE (tushen carbon) + MPP (tushen iskar gas) suna samar da tsarin IFR, suna ƙirƙirar layin char mai rufewa don toshe zafi da iskar oxygen.
- Haɗin gwiwar zinc borate:Yana amsawa da aluminum hypophosphite don samar da wani tsari mai kariya kamar gilashi, yana ƙara juriyar harshen wuta a lokacin iskar gas.
- An gyara aluminum hydroxide:Maganin saman jiki yana rage fitar da danshi yayin sarrafawa yayin da yake samar da rugujewar endothermic don rage zafin konewa.
- Daidaiton Sarrafawa da Aiki
- Ya kamata a sarrafa jimillar nauyin da ke hana harshen wuta a lokacinKashi 35-45%don guje wa asarar dukiya mai mahimmanci ta injiniya.
- Amfaniresin PP mai ƙarfin MFI (misali, PPH-Y40)don inganta watsawar masterbatch da rage danko.
- Shawarwarin Gwaji & Tabbatarwa
- Gwajin Ƙona Tsaye na UL94:Tabbatar da cewa harshen wuta yana kashe kansa a cikinDaƙiƙa 60bayan an kunna wuta sau biyu.
- Gwajin Inji:Mayar da hankali kan ƙarfin taurin kai (≥20 MPa) da ƙarfin tasiri (≥4 kJ/m²).
- Kwanciyar Hankali ta Zafi (TGA):Tabbatar da yanayin zafi na nakasassu na hana harshen wuta ya yi daidai da kewayon sarrafa PP (180–220°C).
III. Zaɓaɓɓun Gyara
- Don Mafi Girman Jinkirin Wuta (misali, V0):
- Ƙara sinadarin aluminum hypophosphite zuwakashi 25%, ƙarasilicone 2%(dakatar da hayaki), da kuma ƙara PTFE zuwa0.8%.
- Aikace-aikace Masu Sauƙin Kula da Farashi:
- Rage yawan MPP kuma ƙara yawan aluminum hydroxide (tabbatar da daidaiton sarrafawa).
IV. Muhimman Abubuwan Da Za A Yi La'akari da Su
- Samar da Baki na Musamman:Kafin a haɗa na'urorin hana harshen wuta da resin mai ɗaukar kaya;fitar da sukurori biyu (180–210°C)ana ba da shawarar.
- Busar da aluminum hydrooxide:Bushewa a110°C na tsawon awanni 4don hana kumfa yayin sarrafawa.
- Di-PE/Aluminum Hypophosphite Ratio:Kula da1:2 zuwa 1:3don ingantaccen tsarin samar da char.
Tare da wannan ingantaccen tsarin tsari da sarrafawa,UL94 V2 jinkirin harshen wutaana iya cimma nasara akai-akai yayin da ake kiyaye aikin sarrafawa da daidaiton launi. Ana ba da shawarar ƙananan gwaje-gwaje don gyarawa bisa ga sakamakon gwaji.
