Qaab-dhismeedka Tixraaca Masterbatch ee PP V2 ee ka hortagga ololka
Si loo gaaro dib-u-celinta ololka UL94 V2 ee qaybaha ugu muhiimsan ee PP (polypropylene), isku-darka isku-dhafka ah ee dib-u-celinta ololka ayaa loo baahan yahay iyadoo la ilaalinayo waxqabadka habaynta iyo sifooyinka farsamada. Hoos waxaa ku yaal talo soo jeedin qaacido la habeeyay oo leh sharraxaad:
I. Talada Qaabaynta Saldhigga
Qaab-dhismeedka Ka-hortagga Ololka:
| Qaybta | Soo raraya (wt%) | Sharaxaadda Shaqada |
| Resin PP | 50-60% | Resin-ka side (waxaa lagu talinayaa heerka heerka qulqulka dhalaalka sare, tusaale ahaan, MFI 20-30 g/10 daqiiqo) |
| Aluminium Hypophosphite | 15-20% | Ilo aashito ah, waxay kor u qaaddaa sameynta char, xasillooni kuleyl oo wanaagsan oo loogu talagalay farsamaynta PP |
| Zinc Borate | 5-8% | Dawada dabka ee isku dhafan, waxay xakameysaa qiiqa waxayna xoojisaa dib u dhigista dabka marxaladda gaaska |
| Aluminium Hydroxide oo Dusha Sare laga Beddelay | 10-15% | Kala-go'idda endothermic, waxay hoos u dhigtaa heerkulka gubashada (daaweynta dusha sare, tusaale ahaan, wakiilka isku xidhka silane, ayaa lagu talinayaa) |
| Dipentaerythritol (Di-PE) | 5-8% | Isha kaarboon, waxay la midaysaa isha aashitada si ay u sameyso char intumescent ah |
| Melamine Polyphosphate (MPP) | 3-5% | Isha gaaska (kabitaan lagu taliyay), waxay sii deysaa gaasaska aan firfircooneyn si kor loogu qaado iftiinka |
| Wakiilka Ka-hortagga Dhibicda (PTFE) | 0.3-0.5% | Waxay yareysaa daadinta dhalaalka (ikhtiyaar u ah V2, maadaama daadinta la oggol yahay) |
| Ka-hortagga oksaydheynta (1010/168) | 0.3-0.5% | Waxay ka hortagtaa burburka oksaydhka kulaylka inta lagu jiro farsamaynta |
| Saliidayn (Zinc Stearate) | 0.5-1% | Waxay hagaajisaa socodka iyo kala firdhinta habka |
| Midabka Qaadaha & Midabka | Sida loogu baahan yahay | Dooro midabyo u adkaysta heerkulka sare si aad uga fogaato falcelinta waxyaabaha ka hortagaya ololka |
II. Qodobbada Muhiimka ah ee Hagaajinta
- Nidaamka Ka-hortagga Ololka ee Isku-dhafan
- Dib-u-dejinta Ololka Dabciga ah (IFR):Aluminium hypophosphite (ilaha aashitada) + Di-PE (ilaha kaarboon) + MPP (ilaha gaaska) waxay sameeyaan nidaam IFR ah, iyagoo abuuraya lakab dahaadh ah si loo xakameeyo kulaylka iyo oksijiinta.
- Isku-darka Zinc Borate:Waxay la falgashaa aluminium hypophosphite si ay u sameyso lakab difaac galaas ah, taasoo kor u qaadaysa dib u dhigista ololka wejiga gaaska.
- Aluminium Haydaroksaydh oo wax laga beddelay:Daawaynta dusha sare waxay yareysaa sii deynta qoyaanka inta lagu jiro farsamaynta iyadoo la siinayo burburka endothermic si loo yareeyo heerkulka gubashada.
- Habaynta iyo Dheelitirka Waxqabadka
- Rarista guud ee dab-damiska waa in la xakameeyaa35-45%si looga fogaado khasaare weyn oo hanti farsamo.
- Isticmaalresin PP oo MFI sare leh (tusaale ahaan, PPH-Y40)si loo hagaajiyo kala firdhinta heerka sare iyo in la yareeyo dheellitirka.
- Talooyinka Tijaabada & Xaqiijinta
- Tijaabada Gubashada Toosan ee UL94:Hubi in ololku iskiis u damiyo gudaha60 ilbiriqsika dib laba dab-shid.
- Tijaabada Farsamada:Xoogga saar xoogga jiidista (≥20 MPa) iyo xoogga saameynta (≥4 kJ/m²).
- Xasiloonida Kulaylka (TGA):Hubi heerkulka kala-baxa dabka ee la jaanqaadaya heerka wax-soo-saarka PP (180–220°C).
III. Hagaajinta Ikhtiyaarka ah
- Loogu talagalay Dib-u-celinta Ololka Sare (tusaale ahaan, V0):
- Kordhi hypophosphite-ka aluminiumka ilaa25%, ku dar2% silikoon(cabburinta qiiqa), oo kor u qaad PTFE ilaa0.8%.
- Codsiyada Xasaasiga ah ee Kharashka:
- Yaree tirada MPP oo si dhexdhexaad ah u kordhi aluminium hydroxide (hubi xasilloonida habaynta).
IV. Tixgelinnada Muhiimka ah
- Wax soo saarka heerka sare ah:Isku qas waxyaabaha dabka celiya oo leh resin side ah kahor;fidinta laba-boolal (180–210°C)ayaa lagu talinayaa.
- Qalajinta Aluminium Haydrooksaydh:Qallaji marka110°C muddo 4 saacadood ahsi looga hortago xumbo inta lagu jiro farsamaynta.
- Heerka Di-PE/Aluminium Hypophosphite:Hagaajin1:2 ilaa 1:3si loo helo hufnaan ugu wanaagsan sameynta xarfaha.
Iyada oo la adeegsanayo habkan habaynta iyo habaynta ee la hagaajiyay,UL94 V2 dib u dhac ololsi joogto ah ayaa loo gaari karaa iyadoo la ilaalinayo waxqabadka habaynta iyo xasilloonida midabka. Tijaabooyin yaryar ayaa lagu talinayaa si loo hagaajiyo iyadoo lagu saleynayo natiijooyinka baaritaanka.
