PP V2 Dejinta Ololka Masterbatch ee Tixraaca
Si loo gaaro dib u dhac ololka UL94 V2 ee PP (polypropylene) masterbatches, isku-darka isku-dhafka ah ee dib-u-celinta ololka ayaa loo baahan yahay iyadoo la ilaalinayo waxqabadka farsamaynta iyo sifooyinka farsamada. Hoos waxaa ah talooyinka habaynta la hagaajiyay oo leh sharraxaad:
I. Talo bixinta Saldhigga
Samaynta Ololka Retardant:
| Qayb | Soodejinaya (wt%) | Sharaxaada Shaqada |
| PP xabagta | 50-60% | Xabagta xanbaarsan (ku taliyay heerka tusaha socodka dhalaalka sare, tusaale, MFI 20-30 g/10min) |
| Aluminium Hypophosphite | 15-20% | Isha acid, waxay kor u qaadaa samaynta dhuxusha, xasilloonida kulaylka wanaagsan ee habaynta PP |
| Zinc Borate | 5-8% | Dab-dejinta holac isku-dhafan, wuxuu xakameeyaa qiiqa wuxuuna wanaajiyaa dib u dhaca ololka-wajiga gaaska |
| Aluminium Hydroxide oo dusha sare laga beddelay | 10-15% | Burburka Endothermic, wuxuu hoos u dhigaa heerkulka gubashada (daawaynta dusha sare, tusaale ahaan, wakiilka isku xidhka silane, lagu taliyay) |
| Dipentaerythritol (Di-PE) | 5-8% | Isha kaarboon, waxay la shaqaysaa isha aashitada si ay u samaysato dhuxul dareen leh |
| Melamine Polyphosphate (MPP) | 3-5% | Ilaha gaaska (kabka lagu taliyay), ayaa sii daaya gaasas aan shaqaynayn si kor loogu qaado dareenka |
| Wakiilka-Dripping (PTFE) | 0.3-0.5% | Waxay yaraynaysaa qulqulka dhalaalka (ikhtiyaar ah V2, sida faleexdu waa la oggol yahay) |
| Antioxidant (1010/168) | 0.3-0.5% | Waxay ka hortagtaa nabaad-guurka kulaylka inta lagu jiro habaynta |
| Saliid (Zinc Stearate) | 0.5-1% | Waxay wanaajisaa socodsiinta socodka iyo kala firdhinta |
| Midabka Side & Midabka | Sida loo baahdo | Dooro midabada heerkulka u adkaysta si aad uga fogaato falcelinta ololka |
II. Qodobbada Horumarinta Muhiimka ah
- Nidaamka Dib u Celinta Ololka Isku-dhafka ah
- Dib-u-dejinta Ololka Dabciga ah (IFR):Aluminium hypophosphite (ilo aysiidh ah) + Di-PE ( isha kaarboon) + MPP ( isha gaaska) waxay sameeyaan nidaamka IFR, abuurista lakabka dhuxusha si uu u xannibo kulaylka iyo ogsijiinta.
- Isku-dhafka Zinc Borate:Waxay ku falcelisaa hypophosphite aluminium si ay u samayso lakab ilaalin dhalo leh, kor u qaadaysa dib u dhaca ololka wajiga gaaska.
- Aluminium Hydroxide la beddelay:Daawaynta dusha sare waxay yaraynaysaa sii daynta qoyaanka inta lagu jiro habaynta iyada oo la siinayo kala-goynta endothermic si ay hoos ugu dhigto heerkulka gubashada.
- Habaynta & Hadhaaga Waxqabadka
- Wadarta guud ee rarista ololka waa in lagu xakameeyaa35-45%si looga fogaado khasaare weyn oo hantiyeed.
- Isticmaalxabagta PP-MFI sare (tusaale, PPH-Y40)si loo hagaajiyo fidinta masterbatch loona yareeyo viscosity.
- Tijaabinta & Talooyinka Ansixinta
- UL94 Tijaabada Gubashada Toosan:Hubi in ololka uu gudaha ku bakhtiiyo60 ilbiriqsilaba shid ka dib.
- Tijaabada Makaanikada:U fiirso xoogga xajinta≥20 MPa) iyo xoogga saamaynta (≥4 kJ/m²).
- Xasilloonida kulaylka (TGA):Hubi heerkulka kala-goynta ololka inuu iswaafajiyo kala duwanaanta habaynta PP (180-220°C).
III. Hagaajinta Ikhtiyaarka
- Dib u Dhigista Ololka Sare (tusaale, V0):
- Kordhi aluminium hypophosphite ilaa25%, ku dar2% silicone(xakamaynta qiiqa), oo kor u qaad PTFE0.8%.
- Codsiyada xasaasiga ah:
- Yaree waxa ku jira MPP oo si dhexdhexaad ah u kordhi aluminium hydroxide (hubi xasilloonida habaynta).
IV. Tixgelinta Muhiimka ah
- Soo saarista Masterbatch:Horay ugu qas dib-u-kicinta ololka iyo xabagta side;extrusion mataano ah (180-210°C)ayaa lagula talinayaa.
- Qallajinta Aluminium Hydroxide:Ku qallaji110 ° C ilaa 4 saacadoodsi looga hortago xumbo inta lagu jiro habaynta.
- Heerka Di-PE/Aluminium Hypophosphite:Ilaali1:2 ilaa 1:3si loo helo waxtarka samaynta char ee ugu fiican.
Habkan habaynta iyo habaynta ee la wanaajiyey,UL94 V2 dib u dhigista ololkasi joogto ah ayaa loo gaari karaa iyadoo la ilaalinayo waxqabadka processing iyo xasilloonida midabka. Tijaabooyin yar-yar ayaa lagula talinayaa in si fiican loo hagaajiyo iyadoo lagu saleynayo natiijooyinka imtixaanka.
