PP V2 Flame Retardant Masterbatch Reference Formulation
Don cimma nasarar jinkirin harshen wuta na UL94 V2 a cikin PP (polypropylene) masterbatches, ana buƙatar haɗin haɗin gwiwar wutan wuta yayin kiyaye aikin sarrafawa da kaddarorin injina. A ƙasa akwai ingantaccen shawarwarin ƙira tare da bayani:
I. Shawarar Tsarin Tushen
Ƙirƙirar Ƙunƙarar Harshen Harshe:
| Bangaren | Ana lodawa (wt%) | Bayanin Aiki |
| Farashin PP | 50-60% | Guduro mai ɗaukar kaya (yana ba da shawarar ma'auni mai girma na narkewa, misali, MFI 20-30 g/10min) |
| Aluminum Hypophosphite | 15-20% | Tushen acid, yana haɓaka haɓakar char, kyakkyawan kwanciyar hankali na thermal don sarrafa PP |
| Zinc Borate | 5-8% | Ƙunƙarar harshen wuta na haɗin gwiwa, yana hana hayaki kuma yana haɓaka jinkirin lokacin harshen iskar gas. |
| Aluminum Hydroxide da aka gyaggyara | 10-15% | Bazuwar Endothermic, yana rage zafin konewa (maganin saman, misali, silane coupling agent, shawarar) |
| Dipentaerythritol (Di-PE) | 5-8% | Tushen carbon, yana aiki tare da tushen acid don samar da char intumescent |
| Melamine Polyphosphate (MPP) | 3-5% | Tushen iskar gas (karin da aka ba da shawarar), yana fitar da iskar gas don haɓaka haɓakar haɓaka |
| Wakilin Anti-Dripping (PTFE) | 0.3-0.5% | Yana rage narkewa (na zaɓi don V2, kamar yadda aka ba da izinin ɗigo) |
| Antioxidant (1010/168) | 0.3-0.5% | Yana hana thermal oxidative lalata yayin aiki |
| Man shafawa (Zinc Stearate) | 0.5-1% | Yana haɓaka iya aiki da tarwatsawa |
| Mai ɗaukar launi & Pigment | Kamar yadda ake bukata | Zaɓi pigments masu jure zafin jiki don gujewa halayen wuta tare da masu riƙe wuta |
II. Maɓallin Inganta Maɓalli
- Tsarin Tsare-tsare Harshen Harshe
- Ƙunƙarar Harshen Harshen Wuta (IFR):Aluminum hypophosphite (tushen acid) + Di-PE (tushen carbon) + MPP (tushen iskar gas) yana samar da tsarin IFR, yana haifar da shinge mai rufewa don toshe zafi da iskar oxygen.
- Zinc Borate Synergy:Yana amsawa tare da aluminium hypophosphite don samar da Layer na kariya mai gilashi, yana haɓaka jinkirin lokacin wuta.
- Gyaran Aluminum Hydroxide:Maganin saman yana rage sakin danshi yayin aiki yayin samar da bazuwar endothermic zuwa ƙananan zafin konewa.
- Ma'aunin sarrafawa & Aiki
- Yakamata a sarrafa jimlar ɗorawa mai ɗaukar wuta a35-45%don kauce wa gagarumin asarar dukiya na inji.
- Amfaniresin PP mai girma-MFI (misali, PPH-Y40)don inganta masterbatch watsawa da rage danko.
- Gwaji & Tabbatarwa Shawarwari
- Gwajin Kona Tsaye na UL94:Tabbatar cewa harshen wuta ya kashe kansa a ciki60 secondsbayan wuta biyu.
- Gwajin Injini:Mayar da hankali kan ƙarfin juriya (≥20 MPa) da ƙarfin tasiri (≥4 kJ/m²).
- Ƙarfin Ƙarfi (TGA):Tabbatar da yanayin bazuwar harshen wuta ya dace da kewayon sarrafa PP (180-220 ° C).
III. gyare-gyare na zaɓi
- Don Tsarewar Harshen Wuta (misali, V0):
- Ƙara aluminum hypophosphite zuwa25%, ƙara2% silicone(shafin hayaki), da ɗaga PTFE zuwa0.8%.
- Aikace-aikace masu tsada:
- Rage abun ciki na MPP kuma ƙara matsakaicin aluminium hydroxide (tabbatar da kwanciyar hankali na aiki).
IV. Mahimmin La'akari
- Samar da Masterbatch:Pre-hada masu retardat na harshen wuta tare da guduro mai ɗauka;extrusion tagwaye (180-210 ° C)ana bada shawarar.
- Aluminum Hydroxide bushewa:bushe a110 ° C na 4 hoursdon hana kumfa yayin sarrafawa.
- Di-PE/Aluminum Hypophosphite Ratio:Kula1:2 zuwa 1:3don ingantaccen ingancin samuwar char.
Tare da wannan ingantaccen tsari da tsarin sarrafawa,UL94 V2 jinkirin harshen wutaza a iya ci gaba da samun ci gaba yayin kiyaye aikin sarrafawa da kwanciyar hankali na launi. Ana ba da shawarar ƙananan gwaji don daidaitawa bisa sakamakon gwajin.
