Hauv kev lag luam niaj hnub no, khau kev nyab xeeb tau dhau los ua yam tseem ceeb ntawm Cov Khoom Siv Tiv Thaiv Tus Kheej (PPE). Tsim los tiv thaiv cov neeg ua haujlwm ko taw, khau kev nyab xeeb muab kev tiv thaiv kev cuam tshuam thiab kev phom sij. Nyob ntawm qhov chaw ua haujlwm sib txawv, lawv tuaj yeem nruab nrog cov haujlwm ntxiv xws li kev ua haujlwm tsis zoo, tiv thaiv- zoo li qub, tiv thaiv roj, thiab lwm yam.
Qhov no ua rau ntau tus neeg nug:Thaum twg yog khau kev nyab xeeb tsim?
Txoj kev loj hlob ntawm cov khau kev nyab xeeb yog sib txuas nrog keeb kwm ntawm industrialization. Lawv tsis tshwm ib hmos. Hloov chaw, lawv tau hloov zuj zus los ntawm kev sib koom ua ke ntawm kev xav tau ntawm kev lag luam, kev nce qib hauv cov khoom siv thev naus laus zis, thiab kev paub txog kev nyab xeeb ntawm chaw ua haujlwm.
1. Lub hauv paus chiv keeb ntawm kev nyab xeeb khau: Thaum ntxov tiv thaiv khau thaum lub sij hawm muaj kiv puag ncig
Cov ntaub ntawv ntxov tshaj plaws ntawm nkawm khau kev nyab xeeb tuaj yeem taug qab mus rau xyoo 19th Industrial Revolution (kwv yees li 1800s).
Los ntawm lub xyoo pua 18th mus txog rau xyoo pua 19th, Tebchaws Europe thiab Tebchaws Meskas tau ntsib kev lag luam loj hlob sai. Muaj coob tus factories, mines, railways, thiab kev tsim kho tej yaam num tau tsim. Cov neeg ua haujlwm yuav tsum ua cov tshuab hnyav, tuav cov khoom siv, thiab ua haujlwm lub cev xav tau txhua hnub.
Lub sijhawm ntawd, cov neeg ua haujlwm feem ntau tsuas hnav khau zoo tib yam thaum ua haujlwm. Cov khau no muaj kev tiv thaiv me me tiv thaiv kev tsim kev puas tsuaj xws li cov khoom hnyav poob, cov hlau tawg tawg, lossis kev ua haujlwm txaus ntshai.
Txhawm rau txo qis kev raug mob ntawm chaw ua haujlwm, qee lub chaw tsim khoom tau pib xav kom cov neeg ua haujlwm hnav cov khau tawv tawv tawv dua thiab ruaj khov dua. Hauv qee qhov chaw ua haujlwm nyob sab Europe, cov neeg ua haujlwm tau pib ntxiv cov khoom siv hlau ntxiv nyob ib ncig ntawm cov ntiv taw kom txhim kho kev tiv thaiv.
Txawm hais tias cov khau tiv thaiv thaum ntxov no muaj cov qauv yooj yim, lawv sawv cev rau lub tswv yim tseem ceeb tom qab cov khau kev nyab xeeb niaj hnub no - ntxiv dag zog rau khau tsim los tiv thaiv cov neeg ua haujlwm ko taw los ntawm kev raug mob.
2. Txoj Kev Txhim Kho ntawm Cov Hlau Ntiv Taw Safety Khau
Lub tswv yim niaj hnub ntawm kev nyab xeeb khau tau pib zoo nyob rau hauv thaum ntxov 20th caug xyoo.
Nrog rau kev loj hlob sai ntawm kev lag luam xws li kev tsim tsheb, kev tsim kho tshuab, kev tsim kho, thiab mining, kev pheej hmoo ntawm chaw ua haujlwm tau nce ntau. Cov khau tawv tawv tsoos tsis muaj peev xwm ua tau raws li qhov yuav tsum tau muaj kev nyab xeeb, tsim kom muaj cov khau tiv thaiv kev tshaj lij.
Thaum Ntiaj Teb Tsov Rog Thoob Ntiaj Teb thib 1 thiab Tsov Rog Ntiaj Teb Zaum II, qhov kev thov rau cov khau tiv thaiv tau nce ntxiv vim yog kev ua tub rog thiab kev lag luam loj -. Lub sijhawm no tau nrawm rau kev txhim kho kev nyab xeeb khau tshuab.
Ib qho tseem ceeb ntawm kev tsim kho tshiab yog qhov kev taw qhia ntawm cov ntiv taw steel.
Lub kaus mom hlau ntiv taw yog lub plhaub tiv thaiv hlau tso rau hauv pem hauv ntej ntawm cov khau kom tiv thaiv kev raug mob ntiv taw hnyav los ntawm cov khoom poob lossis kev cuam tshuam hnyav. Los ntawm thaum ntxov xyoo pua 20th, steel ntiv taw khau tau siv dav hauv kev lag luam xws li thee mining, steel manufacturing, kev tsim kho, thiab kev thauj mus los.
Qhov kev tsim kho tshiab no tau cim lub sijhawm tseem ceeb hauv keeb kwm ntawm kev nyab xeeb khau, hloov cov khau ua haujlwm zoo tib yam rau hauv cov cuab yeej tiv thaiv kev tshaj lij.
3. Kev tsim cov qauv kev ruaj ntseg khau hauv nruab nrab thiab lig 20th caug xyoo
Raws li kev tsim khoom lag luam nthuav dav thoob ntiaj teb, tsoomfwv thiab cov koom haum pom tau hais tias kev nyab xeeb ntawm cov khau hauv chaw ua haujlwm tsis tuaj yeem tso siab rau tus kheej lub tuam txhab tsim. Cov qauv ntsuas kev sib koom ua ke yuav tsum tau ua kom muaj kev tiv thaiv ruaj khov.
Thaum nruab nrab thiab lig xyoo pua 20th, ntau lub teb chaws pib tsim cov qauv kev nyab xeeb khau.
Hauv Tebchaws Europe, lubTS EN ISO 20345 Kev nyab xeeb khau khau qauv systemtau tsim, txhais cov kev xav tau meej rau kev tiv thaiv kev ua haujlwm, suav nrog kev cuam tshuam, compression tsis kam, thiab plam tsis kam.
Hauv Tebchaws Meskas, cov koom haum xws liASTM Internationaltsim cov qauv kev nyab xeeb khau los tswj cov kev sim thiab kev ua haujlwm ntawm cov khau tiv thaiv kev lag luam.
Cov qauv no tau pab cov khau kev nyab xeeb hloov zuj zus los ntawm qhov yooj yim "cov khau ua haujlwm muaj zog" rau hauv kev sim tshuaj thiab tau ntawv pov thawj cov cuab yeej tiv thaiv kev tshaj lij.
4. Niaj hnub nimno khau kev nyab xeeb: Los ntawm kev tiv thaiv kom xis nyob
Nkag mus rau xyoo pua 21st, txoj kev loj hlob ntawm cov khau kev nyab xeeb tau hloov pauv ntau.
Cov khau kev nyab xeeb ib txwm muaj kev tiv thaiv zoo heev tab sis kuj muaj qee qhov tsis zoo, suav nrog qhov hnyav hnyav, tsis muaj kev ua pa, zoo li loj, thiab txo kev nplij siab thaum lub sijhawm ua haujlwm ntev.
Nrog kev nce qib hauv kev ua kis las ncaws pob thev naus laus zis, nkawm khau kev nyab xeeb niaj hnub tau pib sib koom ua ke kev tiv thaiv kev lag luam nrog cov qauv tsim khau kis las.
Niaj hnub no cov khau kev nyab xeeb tsom rau ntau qhov chaw tseem ceeb:
1. Lub teeb yuag tsim
Cov tsoos hlau ntiv taw kev nyab xeeb khau feem ntau hnyav dua vim lawv cov khoom siv hlau. Niaj hnub nimno kev nyab xeeb khau nce siv cov khoom hnyav hnyav, suav nrog:
Composite ntiv taw caps
Fiberglass ntiv taw caps
Kevlar puncture-resistant midsoles
Cov ntaub ntawv no muab kev tiv thaiv muaj zog thaum txo qis tag nrho cov khau hnyav thiab txhim kho kev hnav zoo.
2. Kev ua si nawv-Kev tshwm sim tshwm sim
Cov khau kev nyab xeeb niaj hnub no tsis txwv rau cov khau ua haujlwm hnyav hnyav.
Ntau cov qauv tsim tshiab siv cov khoom siv feem ntau pom hauv cov khau kis las, xws li:
Knitted sab saum toj
Breathable mesh fabrics
Lub teeb yuag EVA outsoles
Yooj yim ergonomic insoles
Yog li ntawd, nkawm khau kev nyab xeeb niaj hnub zoo li zoo li khau kis las, ua rau cov neeg ua haujlwm txaus siab rau kev tiv thaiv thiab kev nplij siab thaum ua haujlwm thiab ua haujlwm txhua hnub.
Xaus
Los ntawm cov khau tawv tawv yooj yim rau cov khau tiv thaiv niaj hnub no, kev hloov pauv ntawm cov khau kev nyab xeeb ib txwm tsom mus rau ib lub hom phiaj tseem ceeb: tiv thaiv cov neeg ua haujlwm ko taw thaum txhim kho kev nplij siab thiab kev nyab xeeb ntawm chaw ua haujlwm.
Nrog kev nce qib txuas ntxiv hauv kev lag luam thev naus laus zis thiab cov khoom siv tshawb fawb, cov khau kev nyab xeeb yav tom ntej yuav dhau los ua sib dua, ntse dua, zoo ib puag ncig, thiab zoo dua rau kev ua haujlwm niaj hnub no.
Kev nyab xeeb khau tsis yog cov cuab yeej tiv thaiv nkaus xwb - nws tau dhau los ua kev nyab xeeb, thev naus laus zis, kev nplij siab, thiab kev tsim qauv niaj hnub.
Raws li cov kws tshaj lij Tuam Tshoj khau tsim khoom lag luam, Zstep txuas ntxiv tsim kho tshiab los ntawm kev sib txuas cov thev naus laus zis kev nyab xeeb, kev tsim qauv niaj hnub, thiab kev tsim cov kws tshaj lij los muab cov kev daws teeb meem khau khau rau cov neeg ua haujlwm thoob ntiaj teb.
