Hauv kev siv cawm, kev xaiv ntawm webbing yog qhov tseem ceeb vim qhov xav tau tshwj xeeb lub zog, ua haujlwm ntev, thiab ua haujlwm rau ntau yam ib puag ncig. Ob cov ntaub ntawv uas tau pom zoo rau lawv cov khoom zoo tshaj plaws hauv kev cawm webbing yog Aramid (feem ntau hu ua Kevlar®) thiab Ultra-High-Molecular-Weight Polyethylene (UHMWPE).
Aramid (Kevlar®) Webbing:
Aramid fibers, xws li Kevlar®, paub txog lawv lub zog tensile siab thiab tsis kam mus txiav thiab puas. Nov yog vim li cas aramid webbing feem ntau siv hauv kev siv cawm:
- High Strength-rau-Weight Ratio:Aramid fibers muab lub zog-rau-hnyav piv, ua rau lub webbing muaj zog tsis tau hnav, uas yog qhov zoo tagnrho rau kev cawm siav uas cov cuab yeej yuav tsum tau nqa mus ntev.
- Thaum tshav kub kub Resistance:Aramid webbing muaj cov cua kub zoo heev, uas yog qhov tseem ceeb rau kev cawm cov xwm txheej uas yuav cuam tshuam nrog hluav taws lossis raug kub kub.
- Abrasion Resistance:Cov khoom siv muaj zog heev rau kev puas tsuaj, kom ntseeg tau tias lub webbing tuav nws txoj kev ncaj ncees txawm tias rubbed tawm tsam qhov chaw ntxhib.
- Chemical Stability:Aramids ruaj khov nyob rau hauv ntau yam tshuaj ib puag ncig, uas yog ib qho tseem ceeb nyob rau hauv chemical spill los yog industrial cawm.
- Txiav Resistance:Cov cuab yeej txiav-tiv taus ntawm aramid webbing ua rau nws haum rau qhov chaw ruaj khov lossis muaj kev phom sij.
UHMWPE (Ultra-High-Molecular-Weight Polyethylene) Webbing:
UHMWPE yog lwm cov khoom siv uas tau siv ntau dua hauv kev cawm webbing vim nws lub zog tshwj xeeb thiab ua haujlwm ntev:
- Superior Strength:UHMWPE muaj lub zog-rau-qhov hnyav piv uas piv rau aramid fibers, muab lub zog tshwj xeeb rau kev nqa thiab kev ruaj ntseg.
- Tsawg Stretch:UHMWPE webbing muaj qhov elongation tsawg heev nyob rau hauv load, kom ntseeg tau tias nws tswj nws cov duab thiab tsis stretch tawm thaum lub sij hawm cawm hauj lwm.
- UV Resistance:Cov khoom siv no muaj kev tiv thaiv zoo rau UV hluav taws xob, ua rau nws tsim nyog rau kev siv sab nraum zoov mus ntev yam tsis muaj degradation.
- Floatation:UHMWPE muaj qhov ntom ntom dua li dej, uas tso cai rau nws ntab, muaj txiaj ntsig zoo rau kev ua haujlwm cawm dej.
- Puncture thiab Abrasion Resistance:UHMWPE webbing yog resistant rau punctures thiab abrasions, tswj nws lub zog txawm nyob rau hauv ntxhib tej yam kev mob.
- Tsis-Conductive:UHMWPE tsis ua hluav taws xob, uas yog ib qho tseem ceeb ntawm kev nyab xeeb hauv ib puag ncig uas muaj hluav taws xob txaus ntshai.
Ob qho tib si aramid thiab UHMWPE webbing cov ntaub ntawv yog cov kev xaiv zoo tshaj plaws rau kev cawm cov ntawv thov vim lawv qhov sib xyaw ua ke ntawm lub zog, ruaj khov, thiab tsis kam mus rau ntau yam ib puag ncig. Lawv feem ntau siv rau hauv cov cuab yeej cawm txoj sia xws li cov hlua khi, cov hlua, thiab cov txheej txheem tuav, qhov kev ntseeg siab thiab kev ua tau zoo yog qhov tseem ceeb.
