Ob qho tib si aramid ntaub thiab Dyneema webbing yog cov khoom siv ua haujlwm siab, txhua tus muaj lub cev tshwj xeeb thiab daim ntawv thov.
Aramid npuag, tshwj xeeb tshaj yog aramid npuag woven los ntawm aramid 1414 fibers, muaj zog heev, 5-6 lub sij hawm ntawm high-zoo hlau, 2-3 lub sij hawm lub modulus ntawm hlau los yog fiberglass, thiab ob zaug lub toughness ntawm hlau, tab sis tsuas yog 1/5 qhov hnyav ntawm cov hlau. Aramid muaj qhov dav dav siv qhov kub thiab txias thiab ua haujlwm ib txwm ntawm -196 degree txog 204 degree . Nws muaj qhov shrinkage ntawm 0 ntawm 150 degree, tsis decompose lossis yaj ntawm qhov kub siab txog 560 degree, thiab muaj cov rwb thaiv tsev zoo thiab corrosion kuj, ua rau nws ruaj khov heev. Aramid npuag muaj kev qaug zog zoo vim tias nws muaj qhov siab elongation ntawm kev tawg thiab zoo heev toughness, uas ua rau nws tuaj yeem rov ua dua lub sijhawm ntev yam tsis muaj kev tawg. Aramid fabrics kuj muaj huab cua tiv thaiv zoo heev thiab tuaj yeem tswj tau lawv qhov kev ua tau zoo hauv qhov kub thiab txias ib puag ncig, ua rau lawv tsim nyog rau ntau yam kev siv sab nraum zoov xws li cov khoom siv conveyor siv, kev nyab xeeb siv thiab kev siv nqa nqa.
Dyneema webbing yog ib qho ultra-high molecular hnyav polyethylene fiber ntau uas yog ob npaug zog li carbon fiber thiab yog ib qho ntawm cov fibers muaj zog tshaj plaws hauv ntiaj teb. Dyneema xov tau zoo heev txiav tsis kam, hluav taws xob tiv thaiv thiab ruaj khov nyob rau hauv UV rays, thiab muaj ib tug du nto thiab tsis tshua muaj coefficient ntawm kev sib txhuam. Dyneema webbing muaj qhov elongation ntawm kev tawg ntawm 3.5%, thiab nws qhov qaug zog tiv thaiv nyob rau hauv khoov yog zoo dua Kevlar, qhia tias nws muaj peev xwm tswj tau nws cov kev ua tau zoo nyob rau hauv rov khoov thiab ncab, qhia zoo qaug zog. Dyneema webbing kuj muaj huab cua zoo, tshwj xeeb tshaj yog nyob rau hauv marine ib puag ncig, thiab tuaj yeem tiv taus dej hiav txwv corrosion thiab UV yaig, ua rau nws tsim nyog rau kev siv marine engineering xws li nkoj mooring thiab dej hiav txwv-mus towing.
Aramid fabrics ua tau zoo dua hauv qhov kub thiab txias thiab tshuaj tiv thaiv corrosion, thaum Dyneema webbing ua tau zoo dua hauv kev txiav tsis kam thiab UV tsis kam. Ob leeg muaj kev qaug zog zoo heev, tab sis Aramid ntaub yuav ruaj khov dua hauv qhov kub thiab txias. Hais txog huab cua tsis kam, ob qho tib si Aramid npuag thiab Dyneema webbing tuaj yeem tswj hwm qhov kev ua haujlwm hnyav, tab sis Dyneema webbing yuav tsim nyog rau kev siv dej hiav txwv. Thaum xaiv cov ntaub ntawv, cov kev thov tshwj xeeb thiab ib puag ncig yuav tsum tau txiav txim siab los txiav txim siab seb cov khoom siv twg.
