HDPE (high-ntom polyethylene) tau siv dav hauv cov kav dej siab, qhov chaw, thiab cov hnab nqa khoom. Ib qho laj thawj tseem ceeb yog nws lub zog siab flucural: 20-30 MPA.
Tsis zoo li softer plastics zoo li LDPE, HDPE tsis yog khoov-nwsKev tawm tsam deformation nyob rau hauv load, ua rau nws zoo tagnrho rau cov ntawv thov xav tau.
Dab tsi yog flextral lub zog-thiab vim li cas nws tseem ceeb
- Flexural zog=tsis kam rau khoov hauv qab.
Xav txog cov yeeb nkab hauv qab cov av siab, lossis ib qho geomembrane thoob plaws hauv av. Yog tias cov khoom khoov tau yooj yim heev, nws ua tsis tiav. HDPE lub zog txhais tau tiasNws tuav nws cov duab uas lwm tus plastics muab rau hauv.
HDPE vs Lwm cov plastics: tus yeej ntshiab hauv kev tawv ncauj
| Khoom | FLEXURAL LUB ZOG (MPA) | Ua yeeb yam |
|---|---|---|
| HDPE | 20–30 | Nruj, txhim khu kev qha nyob rau hauv kev ntxhov siab |
| Ldpe | 8–15 | Mos, khoov tau yooj yim |
| Pp | 25–40 | Txhav, nkig thaum txias |
HDPE Hits lubqab zib-Qhov -Stronger tshaj LDPE, cuam tshuam ntau-tiv taus dua li pp.
Dab tsi txhawb lossis txo tus HDPE lub zog flexural zog?
- Siab molecular nyhav & ntom=muaj zog ntau
- Txias txias kub =} ntau nkig
- Cov fiber ntau lossis cov ntxhia fille=muaj zog thiab ntau dua
UV thiab Tshuaj lom neegtej zaum yuav tsis muaj zog nyob rau lub sijhawm ntxiv kev pab tiv thaiv qhov no
Tested for Performance: Astm D790
HDPE lub zog flexural yog ntsuas siv covASTM D790Txheem- apeb-taw tes khoovuas simulates tiag-ntiaj teb siab thiab dabtsi yog khoov thauj khoom.
Qhov no ua kom muaj cov khoom siv HDPE siv hauv koj cov khoom tsis yog theoretical-nws tau sim thiab ua pov thawj.
Qhov twg FLEXURAL LUB HWJCHIM TSEEM CEEB HEEV
- Siab Kav:Yuav tsum tsis txhob ua yeeb yaj kiab nyob rau hauv hnyav av load lossis sab hauv
- Geomembranes:Yuav tsum tau nyob tiaj thiab nruj thoob plaws thaj av tsis xwm yeem
- Muaj Panels / Ntim:Yuav tsum muaj zog los tuav cov duab hauv kev ntxhov siab, stacking, lossis cuam tshuam
Xaus: Flexural zog ua rau HDPE ib qho qauv hluav taws xob
Nrog ib tug nquag Flexural lub zog ntawm20-30 MPa, HDPE muaj covzoo meej tshuav ntawm rigidity thiab resilienceCov. Nws yogmuaj zog dua ldpe, kev zam txim ntau dua li nkig plastics, thiab kuaj kom ua hauv kev hnyav, siab thauj khoom.
Rau cov kws ua engineers thiab cov neeg yuav khoom nrhiav ibsiv tau ruaj khov, raug nqi, thiab cov khoom pov thawj, HDPE lub zog flexural yog qhov laj thawj kom xaiv tau.
