PP-LGF30 vs. PP-GF30:Qhov kawg EngineeringQhia rau 30% iav-Pub PP
Xaiv cov khoom tsim nyog yog qhov tseem ceeb rau kev ua tiav cov khoom. Thaum nws los txog rau 30% iav- puv polypropylene, qhov kev xaiv ntawm Long Glass Fiber (LGF30) thiab Short Glass Fiber (GF30) tsis yog ib qho nuance xwb-nws hais txog kev ua haujlwm zoo, qhov ntev, kev zoo nkauj, thiab qhov kawg, ib feem ntawm kev ua haujlwm ntev thiab tus nqi-effectiveness. Cov lus qhia dav dav no muab cov kws tshaj lij, cov kws tsim qauv, thiab cov khoom siv tshwj xeeb nrog cov ntaub ntawv - rov qab sib piv los qhia txog kev xaiv cov khoom zoo.
Dab tsi yog qhov txawv ntawm PP-LGF30 thiab PP-GF30?
Lub ntsiab sib txawv yog nyob rau hauv lubnruab nrab fiber ntev nyob rau hauv qhov kawg molded ib feem. Thaum ob qho tib si muaj 30% iav fiber ntau los ntawm qhov hnyav, txoj kev cov fibers no tau muab tso rau hauv polypropylene matrix cuam tshuam rau lawv cov khoom.
- √ PP-LGF30 (ntev iav Fiber Polypropylene):Feem ntau pib nrog iav fibers 10-25mm nyob rau hauv ntev nyob rau hauv lub pellet. Thaum lub sij hawm txhaj tshuaj molding txheej txheem, cov fibers no txo qis tab sis tuav qhov nruab nrab ntev ntawm>3mm (feem ntau 6-25mm)hauv qhov kawg. Cov fibers ntev, entangled no tsim muaj zog, peb -sab hauv lub cev pob txha.
- √PP-GF30 (Cov iav luv Fiber Polypropylene):Pib nrog fibers tsawg dua 5 hli hauv cov pellet. Ncej- molding, lawv qhov nruab nrab ntev nyob rau hauv feem ntau<1mm. Cov fibers luv luv no feem ntau ua raws li cov khoom siv tsis tu ncua, muab kev txhawb zog hauv zos tab sis tsis muaj kev sib txuas ntawm LGF.
Qhov sib txawv tseem ceeb hauv fiber ntau morphology yog lub hauv paus ua rau muaj kev sib txawv ntawm qhov peb yuav tshawb pom.
Qhov Kev Txiav Txim Siab: LGF30 vs. GF30 ntawm ib sab
| Kev ntsuas | Yeej | Yog vim li cas |

Nws pib ntawm Sab Hauv: Fiber Network
Qhov ua tau zoo sib txawv tsis yog khawv koob - nws yog qhov tseem ceeb ntawm kev siv tshuab. Nyob rau hauv qhov kawg molded ib feem, qhov nruab nrab ntev fiber ntau dictates cov khoom siv sab hauv architecture.
- PP -LGF30:Fibers (feem ntau 5-10mm nyob rau hauv ib feem) interlink thiab intertwine, tsim ib tug robust, kev nyuaj siab-distributing lub cev pob txha. Lub network no tuav cov qauv kev ncaj ncees txawm tias cov polymer matrix tawg, zoo li rebar hauv pob zeb.
- PP -GF30:Fibers (feem ntau<1mm in the part) are dispersed and act more like simple, disconnected fillers. While they stiffen the matrix, they cannot form the continuous load-bearing paths that long fibers do.
Qhov sib txawv ntawm qhov sib txawv ntawm lub microscopic theem yog thawj tsav tsheb rau yuav luag txhua qhov kev ua haujlwm macroscopic sib txawv ntawm LGF thiab SGF composites.
