Lub durability ntawmlawn mower sivnyob ntawm qhov kev xaiv ntawm cov khoom siv thiab cov khoom siv ntxiv. Thaum cov roj hmab tseem yog qhov kev xaiv yooj yim vim nws qhov yooj yim, cov hlua polyester ua kom lub zog tensile, thiab Kevlar fibers ua tau zoo nyob rau hauv siab - kev ntxhov siab - cov neeg ua lag luam qhia tias Kevlar txoj siv sia tuaj yeem siv txuas ntxiv mus txog 200 teev ua ntej hnav.
Roj Hmab, Polyester, thiab Kevlar: Sib piv cov khoom hnav tsis kam
Cov qauv siv roj hmab tawg sai tshaj plaws hauv kev sib txhuam, poob 15-20% ntawm lawv cov tuab txhua 100 teev ntawm kev ua haujlwm hauv kev sim teb. Polyester- siv cov hlua khi, nrog cov hlua khi, txo qhov hnav ntawm 40%. Kevlar cov cua sov- tiv thaiv polymer ua haujlwm zoo dua ob qho tib si, tswj 90% ntawm nws cov qauv kev ncaj ncees txawm tias tom qab 300 teev hauv xoom- tig tshuab txiav.
Qhov zoo ntawm Aramid Cords thiab Composite Reinforcements hauv Hnyav -Cov Khoom Siv Ua Haujlwm
Aramid fiber cores tiv taus ncab zoo dua li cov hlua hlau, ncab tsuas yog 0.3% hauv qab 250- phaus load. Composite siv nrog fiberglass txheej dissipate tshav kub 50% sai dua li cov khoom siv ib leeg, uas yog ib qho tseem ceeb rau kev tiv thaiv glaze buildup thaum lub caij ntuj sov mowing ntev.
Xaiv Cov Khoom Siv Hluav Taws Xob Rau Kev Siv Nrawm
Match siv cov qauv rau kev ua haujlwm:
- <50 hours/season: Roj hmab-polyester hybrids
- 50-200 hnub: Aramid-cov khoom siv zog V- siv
- Kev siv lag luam: Composite siv nrog fiberglass / Nomex® txheej
Nco ntsoov xyuas kev sib tw pulley-txawm tias siab - txoj siv sia kawg yuav hnav 30% sai dua yog tias cov khoom hauv lawj tsis zoo.
