Cov khoom siv raw: polyamide, polypropylene thiab polyester.Txhua txoj hlua yog ua los ntawm ultra-nyias filaments.Hauv qab no yog cov lus qhia txog cov fibers tseem ceeb uas peb siv thiab lawv cov yam ntxwv.
Cov khoom siv nquag siv
Polyamide yog cov khoom siv fiber ntau, uas yog siv los ua cov hlua zoo los ntawm cov khoom siv hluavtaws.Cov hom polyamide uas paub zoo tshaj plaws yog DuPont nylon (PA 6.6) thiab Perlon (PA 6).Polyamide yog hnav-resistant, muaj zog heev thiab elastic heev.Nws tuaj yeem ua kom sov thiab ua kom zoo li qub-qhov no yog siv rau hauv cov txheej txheem kho cua sov.Vim tias qhov xav tau los nqus lub zog, txoj hlua fais fab yog ua los ntawm polyamide nkaus.Polyamide fiber ntau kuj tau siv los ua cov hlua zoo li qub, txawm hais tias cov khoom siv nrog tsawg extensibility raug xaiv.Qhov tsis zoo ntawm polyamide yog tias nws nqus dej ntau dua, uas yuav ua rau nws ntsws yog tias nws ntub dej.
Vim tias nws yog polypropylene, nws yog qhov hnyav heev.
Polypropylene yog lub teeb thiab pheej yig.Vim tias nws tsis hnav tsis kam, polypropylene feem ntau yog siv los ua cov hlua khi, uas tiv thaiv los ntawm polyamide sheaths.Polypropylene yog qhov hnyav heev, tsis tshua muaj txheeb ze thiab tuaj yeem ntab.Yog vim li cas peb thiaj siv los ua peb txoj hlua khi.
Kev siv polyester
Static ropes ua los ntawm polyester fibers yog tsuas yog siv rau cov hauj lwm uas yuav tuaj mus rau hauv kev sib cuag nrog acids los yog corrosive tshuaj.Tsis zoo li polyamide, nws muaj cov kua qaub ntau dua thiab tsis nqus dej.Txawm li cas los xij, polyester fiber ntau tsuas yog txwv lub zog nqus cov yam ntxwv, uas txhais tau hais tias nws siv tau rau PPE tsuas yog txwv.
Ua kom lub zog tsim kua muag siab.
Dynema hlua Dynema yog ib qho hluavtaws fiber ntau ua los ntawm ultra-siab molecular hnyav polyethylene.Nws muaj lub zog tsim kua muag heev thiab tsis tshua muaj elongation.Muab xam los ntawm qhov hnyav piv, nws lub zog tensile yog 15 npaug ntawm cov hlau.Nws cov yam ntxwv tseem ceeb yog hnav tsis kam, siab ultraviolet stability thiab lub teeb yuag.Txawm li cas los xij, Dyneema hlua tsis muab kev nqus lub zog nqus, uas ua rau nws tsis haum rau cov khoom siv tiv thaiv tus kheej.Dyneema hlua feem ntau yog siv los rub cov khoom hnyav.Lawv feem ntau siv es tsis txhob hnyav steel cables.Nyob rau hauv kev xyaum, lub melting point ntawm Dyneema hlua yog tsawg heev.Qhov no txhais tau hais tias cov fibers ntawm Dynema hlua Dynema (ultra-high molecular hnyav polyethylene hlua) yuav puas thaum kub tshaj 135 degrees Celsius.
Ib tug zoo meej txhais ntawm txiav kuj.
Aramid yog ib qho muaj zog heev thiab kub-resistant fiber ntau nrog kev ua haujlwm siab.Zoo li Dyneema hlua, aramid hlua tsis muab lub zog nqus nqus, yog li nws qhov kev siv tau rau PPE yog txwv.Vim tias nws qhov kev nkag siab zoo heev rau kev khoov thiab tsis tshua muaj ultraviolet tsis kam, aramid fibers feem ntau yog muab polyamide sheaths los tiv thaiv lawv.Peb siv txoj hlua aramid los ua txoj hlua khi rau txoj haujlwm ua haujlwm, uas yuav tsum muaj qhov tsawg kawg nkaus extensibility thiab siab txiav.
