Kev xaiv cov khoom siv rau kev siv lanyards yog qhov tseem ceeb hauv kev txiav txim siab lawv cov haujlwm ruaj khov hauv cov xwm txheej tshwj xeeb. Cov ntaub ntawv sib txawv muaj qhov sib txawv tseem ceeb hauv lub cev, tshuaj lom neeg, thiab kev sib cuag ntawm tib neeg. Kev txiav txim siab raws li qhov tshwm sim lossis tus nqi feem ntau ua tsis tau raws li qhov yuav tsum tau ua.Kev xaiv cov khoom siv tshawb fawb yuav tsum pib nrog cov kev xav tau ntawm qhov kev siv scenario, kev ntsuas txhua yam khoom, kev hloov pauv ib puag ncig, kev nyab xeeb, thiab lwm yam haujlwm kom ua tiav qhov sib npaug ntawm "kev siv cov khoom siv ntau tshaj" thiab "kev nyab xeeb thiab kev ntseeg tau."
Hais txog cov khoom siv kho tshuab, fiber ntau- cov ntaub ntawv raws li lub hauv paus nyiam rau feem ntau cov lanyards. Nylon, nrog nws lub zog tensile siab thiab zoo heev abrasion kuj, tswj cov qauv kev ruaj ntseg nyob rau hauv ib puag ncig uas yuav tsum tau hnyav loads los yog tsis tu ncua kev sib txhuam, xws li kev lag luam txij nkawm thiab kev ua hauj lwm sab nraum zoov. Nws resilience kuj pab txo cov kev cuam tshuam tam sim ntawd. Polyester, thaum tuav lub zog zoo, muaj qhov ua tau zoo ntawm UV tiv thaiv thiab huab cua tiv thaiv, tsis yooj yim rau pwm kev loj hlob nyob rau hauv qhov chaw ntub dej, thiab tsim nyog rau kev mus ncig, tsev kawm ntawv, thiab cov xwm txheej nrog lub hnub ntev. Thaum polypropylene yog lub teeb yuag thiab muaj qee qhov buoyancy, nws lub zog kuj qis, feem ntau txwv nws daim ntawv thov rau cov xwm txheej txwv xws li dej-raws li kev pab lossis lub teeb-load signage.
Rau cov ntawv thov uas xav tau ob qho tib si mos thiab kev tiv thaiv tshwj xeeb, cov ntaub ntawv elastomer muaj cov kev xaiv tseem ceeb. Silicone muaj tshuaj lom neeg ruaj khov, nthuav tawm zoo heev thiab kub tsis kam, thiab yooj yim los ntxuav thiab tua kab mob, ua rau nws siv dav hauv kev kho mob, ua zaub mov, thiab cov khoom siv me nyuam. Nws qhov kev sib txhuam ntawm qhov nruab nrab txo qhov kev pheej hmoo ntawm cov khoom ntog. Thermoplastic elastomers (TPEs) muab cov kev hloov pauv ntawm cov roj hmab nrog cov yas ntawm cov yas, tso cai rau kev sib txawv ntawm - ntu thiab los tiv thaiv - cov ntaub nplaum los ntawm kev txhaj tshuaj molding. Lawv kuj muab kev zoo dua ib puag ncig thiab rov ua dua tshiab, ua rau lawv haum rau cov ntawv thov customized nrog cov kev xav tau siab rau cov tsos thiab kev ruaj khov.
Hais txog kev hloov pauv ib puag ncig thiab kev nthuav dav, cov khoom siv thev naus laus zis ua kom cov lanyards kov yeej cov kev txwv ntawm ib qho - daim ntawv thov kev ua tau zoo. Piv txwv li, txheej txheej fiber ntau nrog lub siab -refractive- Performance index reflective film lossis fluorescent txheej tuaj yeem txhim kho pom kev zoo thaum hmo ntuj lossis qis dua - teeb pom kev zoo; qhwv lub siab - lub zog fiber ntau nrog cov kab mob tua kab mob tuaj yeem ua tau raws li cov qauv kev nyiam huv ntawm kev kho mob thiab zaub mov kev lag luam; embedding conductive fibers rau hauv lub substrate tso cai rau siv nyob rau hauv hluav taws xob tsim uas yuav tsum tau electrostatic tiv thaiv los yog nyob rau hauv ib puag ncig flammable thiab tawg. Xws li cov qauv tsim ua qauv qhia txog kev sib koom ua ke ntawm cov khoom siv niaj hnub engineering rau ntau qhov kev xav tau, muab cov lanyards ntxiv tus nqi tshwj xeeb rau qee qhov xwm txheej thaum tswj hwm kev siv tshuab ua haujlwm.
Kev nyab xeeb thiab kev sib cuag ntawm tib neeg cov khoom kuj tseem yog qhov tseem ceeb hauv kev xaiv cov khoom. Lanyards uas tuaj rau hauv kev sib cuag ncaj qha rau ntawm daim tawv nqaij yuav tsum dhau kev kuaj tawv nqaij kom ntseeg tau tias lawv tsis muaj cov khoom ua xua lossis corrosive. Rau cov menyuam yaus cov khoom lag luam, yuav tsum muaj qhov tseem ceeb rau cov khoom tsis muaj - tshuaj lom, tsis muaj ntxhiab, thiab cov khoom muag muag nrog cov txheej txheem los tiv thaiv - strangulation. Environmental cwj pwm kuj tseem ceeb heev; cov ntaub ntawv uas ua raws li RoHS thiab lwm cov qauv kev txwv tsis pub muaj kev phom sij tuaj yeem zam qhov cuam tshuam ntawm cov hlau hnyav lossis cov khoom tsis zoo rau tib neeg kev noj qab haus huv thiab ib puag ncig.
Feem ntau, kev xaiv cov khoom siv rau kev siv lanyards yuav tsum ua raws li peb -pronged hauv paus ntsiab lus ntawm "scenario-kev ua tau zoo-kev nyab xeeb": cov khoom siv yooj yim yuav tsum tau txiav txim siab raws li cov khoom siv thauj khoom, tshuaj lom neeg raug, thiab kev pom kev xav tau ntawm kev siv ib puag ncig; qhov ua tau ntawm cov kev daws teeb meem sib xyaw yuav tsum raug soj ntsuam ua ke nrog cov kev xav tau nthuav dav; thiab kev nyab xeeb thiab kev tiv thaiv ib puag ncig yuav tsum yog cov kab hauv qab kom ntseeg tau thiab ua raws li lub sijhawm ntev - siv. Tsuas yog nyob rau hauv txoj kev no tuaj yeem ua tau raws li lub hom phiaj ua haujlwm thaum ua kom muaj kev nyab xeeb ntawm cov neeg siv khoom thiab cov khoom siv hauv ntau hom kev siv.
