Hlau Hlau Hlau Hlau ropes yuav tsum tiv thaiv kev hloov pauv thaum siv, thiab lawv qhov kev ua tau zoo feem ntau txiav txim siab los ntawm cov khoom siv ntawm cov hlau hlau, nws qhov chaw nto, thiab cov hlua cov qauv. Cov khoom siv hlau hlau muaj xws li carbon steel lossis hlau alloy, ua los ntawm kev kos duab txias lossis txias dov. Cov hlau hla- ntu tuaj yeem yog puag ncig lossis tsis sib xws (T- zoo li, S- zoo li, Z- zoo li). Tsis zoo li tus ntoo khaub lig- cov xov hlau feem ntau yog siv los tsim cov hlua khi steel hlau, muaj zog tensile ntau dua thiab toughness. Kev kho saum npoo tsim nyog yog siv rau cov xov hlau kom ua tau raws li qhov yuav tsum tau ua ntawm qhov chaw ua haujlwm sib txawv.
Rope Core Lub luag haujlwm tseem ceeb ntawm txoj hlua tseem ceeb yog los muab kev txhawb nqa rau cov hlua hlau hlau, ua tiav cov ntoo khaub lig ruaj khov - cov qauv ntu. Cov hlua khi muaj xws li cov tub ntxhais hlau thiab cov tub ntxhais fiber ntau. Fiber cores muaj xws li ntuj fiber cores thiab hluavtaws fiber cores. Ntuj fiber cores muaj xws li sisal, jute, thiab paj rwb xov, thaum hluavtaws fibers muaj xws li polyethylene thiab polypropylene filaments. Natural fiber cores tuaj yeem khaws cov roj nplua nyeem ntau dua, lubricating cov hlua steel hlau thiab txuas nws lub neej kev pab cuam.
Roj yog sprayed thaum lub sij hawm xaim hlua twisting txheej txheem. Nws muaj ob lub luag haujlwm tseem ceeb: ua ntej, txhawm rau txhawm rau cov hlua hlau thiab txo qhov hnav ntawm qhov chaw ntawm cov hlau; Thib ob, txhawm rau cais qhov chaw ntawm cov hlau los ntawm cov pa oxygen hauv huab cua thiab inhibit oxidation thiab corrosion ntawm cov hlua hlau.
