Muraayadaha Dheer ee Fiber-ka La xoojiyay ee Polypropylene (LGFPP)waxay u soo baxday wax rajo ah oo loogu talagalay codsiyada baabuurta sababtoo ah xooggeeda gaarka ah, qallafsanaanta, iyo sifooyinka fudud. Si kastaba ha ahaatee, caqabad weyn oo la xiriirta qaybaha LGFPP ayaa ah rabitaankooda ah inay soo saaraan ur aan fiicnayn. Urtan waxay ka soo bixi karaan ilo kala duwan, oo ay ku jiraan xabagta polypropylene (PP), fiilooyinka muraayadaha dhaadheer (LGFs), wakiilada isku-xidhka, iyo habka qaabeynta duritaanka.
Ilaha urta ee qaybaha LGFPP
1. Saldhig Polypropylene (PP) xabagta:
Soo saarista xabagta PP, gaar ahaan iyada oo loo marayo habka xaalufka peroxide, ayaa soo bandhigi kara peroxides hadhaaga ah ee gacan ka geysta ur. Hydrogenation, oo ah hab kale, waxay soo saartaa PP oo leh urta ugu yar iyo wasakhda haraaga ah.
2. Muraayadaha dhaadheer (LGFs):
LGF-yada laftooda waxaa laga yaabaa inaysan soo dayn ur, laakiin daaweynta dusha sare ee wakiilada isku-xidhka ayaa soo bandhigi kara walxaha ur keena.
3. Wakiilada Isku xidhka:
Waxyaalaha isku-xidhka ah, ee lagama maarmaanka u ah kobcinta isku-xidhka LGFs iyo matrixka PP, waxay gacan ka geysan karaan ur. Maleic anhydride grafted polypropylene (PP-g-MAH), oo ah wakiilka isku xidhka caadiga ah, ayaa sii daaya anhydride lab ah oo ur leh marka aan si buuxda looga falcelin inta lagu jiro wax soo saarka.
4. Habka Duridda:
Heerkulka qaabaynta duritaanka sare iyo cadaadiska waxay u horseedi karaan hoos u dhaca kulaylka PP, taasoo dhalinaysa iskudhisyo kacsan sida aldehyde iyo ketones.
Xeeladaha lagu Yareeynayo Urta qaybaha LGFPP
1. Xulashada agabka:
- Shaqaalayso xabagta PP ee haydaroojiinaysan si loo yareeyo peroxides haraaga ah iyo urta.
- Tixgeli wakiilada isku-xidhka ee beddelka ah ama wanaaji habka tallaalka PP-g-MAH si loo yareeyo anhydride lab ah oo aan falcelin lahayn.
2. Habraaca Hagaajinta:
- Yaree heerkulka qaabaynta duritaanka iyo cadaadiska si loo yareeyo hoos u dhaca PP.
- Shaqaalaysii hawo-mareen wax-ku-ool ah si aad meesha uga saarto isku-dhisyada kacsan inta lagu jiro qaabaynta.
3. Daawaynta ka dib
- Ka faa'iidayso walxaha ur daboolaya ama adsorbents si aad u dhexdhexaadiso ama u qabato molecules ur.
- Tixgeli daawaynta balaasmaha ama korona si aad wax uga bedesho kimistariga dusha sare ee qaybaha LGFPP, yaraynta soo-saarka ur.
Gabagabo
LGFPP waxay bixisaa faa'iidooyin la taaban karo oo loogu talagalay codsiyada baabuurta, laakiin arrimaha urta waxay hor istaagi karaan korsashadeeda baahsan. Fahamka ilaha urta iyo hirgelinta xeeladaha ku habboon, wax-soo-saarayaashu waxay si wax ku ool ah u yareeyaan urta oo ay kor u qaadaan waxqabadka guud iyo rafcaanka qaybaha LGFPP.
