Cov Ntawv Thov: Kev ua zaub mov noj, chav ua noj, khoom txias txias, roj rigs, thiab cov mos lwj ib puag ncig.
Ii. Muaj cov haujlwm tshwj xeeb
Anti-static (Esd)
Rooj mov: Kev ua yeeb yam thuam cov hluav taws xob zoo li qub los tiv thaiv cov zaub mov lossis kev puas tsuaj rau cov khoom siv rhiab.
Cov Ntawv Thov: Cov khoom siv hluav taws xob tsim hluav taws xob, cov nroj tsuag tshuaj, roj av, thiab chaw nres tsheb tawg.
Kev Rwb Hluav Taws Xob
Rooj mov: Insulated soles thiab uppers thaiv hluav taws xob khib nyiab (piv txwv li, en 50321- Daim ntawv pov thawj nkawm khau rau 1000V rwb thaiv tsev).
Cov Ntawv Thov: Kev Tu Hluav Taws Xob, High-Voltage ua haujlwm, thiab nyob Hlau tuav.
Thaum tshav kub kub / txias tsis kam
Rooj mov:
Qho kub: Flame-retardant uppers and heat-resistant soles (e.g., welding shoes withstand >300 degree).
Txias: Cov kab hauv paus tso pa tawm los tiv thaiv Frostbite (piv txwv, khoom txias lossis ua haujlwm sab nraum zoov).
Cov Ntawv Thov: Metallurgy, Vuam, Kev tua hluav taws, thiab txias logistics.
Tshuaj Kuj
Rooj mov: Roj hmab, polyurethane (pu), lossis coated uppers tiv taus cov acids, alkalis, roj, thiab cov kuab tshuaj.
Cov Ntawv Thov: Chaw soj ntsuam, tshuaj chotter, kho yam siv tsheb, thiab ib puag ncig muaj zog.
Anti-rog tsim
Rooj mov: Cushioned insoles (piv txwv li, eva ua npuas ncauj) thiab koov txhawb kom qaug zog qaug zog thaum lub sijhawm sawv ntsug lossis taug kev.
Cov Ntawv Thov: Kho mob, cov khw muag khoom, cov kab sib dhos, thiab cov haujlwm uas yuav tsum tau sawv mus ntev ntev.
III. Ntxiv nta
Dej / Roj Kuj
Rooj mov: Cov tawv ntoo waterproof lossis ntim cov qauv tsim thaiv cov kua nkag.
Cov Ntawv Thov: Ua haujlwm sab nraum zoov, ua zaub mov, thiab kev lag luam ntxuav.
Antimicrobial & tsw tswj
Rooj mov: Cov kab mob tua kab mob tsis sib haum thiab txo cov ntxhiab tsw.
Cov Ntawv Thov: Kev kho mob, kev ua zaub mov, thiab huab cua noo.
Lub Hnav Txom Nyem
Rooj mov: Carbon fiber lossis polymer ntiv taw hloov cov hlau kom txo qhov hnyav tsis muaj kev tiv thaiv.
Cov Ntawv Thov: Cov neeg ua haujlwm xa khoom, cov tsev cawm kev cawm siav, thiab lub luag haujlwm xav tau kev mus ncig.
IV. Cov Qauv Txheej Txheem Thoob Ntiaj Teb & Ntawv Pov Thawj
En ISO 20345: European tus qauv rau kev cuam tshuam, purgure, thiab zoo li qub.
ASTM F2413: Peb tus qauv rau kev cuam tshuam, kev sib zog, thiab hluav taws xob kev sib txheeb.
CSA Z195: Canadian tus qauv rau plam tsis kam thiab kev tiv thaiv txias.
V. Qhov Kev Xaiv Tseem Ceeb
Kev tiv thaiv kev pheej hmoo tshwj xeeb: Sib phim rau cov xwm txheej (piv txwv li, tshuaj lom neeg Kuj + ESD rau cov chaw tshwj xeeb).
Nplij siab: Xyuas kom muaj kev haum kom tsis txhob muaj kev phom sij kev nyab xeeb los ntawm kev tsis xis nyob.
Yam pauv chaw: Cov khau khau yog tias cov hnav tso tawm, ntiv taw lub kaus mom deform, lossis cov ntaub ntawv degrade.
Cov Khaub Ncaws Kev Nyab Xeeb Kev Nyab Xeeb Kev Nyab Xeeb Lub Cev, Tshuaj Lom Zem, thiab Kev Pheej Hmoo,Tiv thaiv kev raug mob ko tawThiabTxhim Kho Kev Nyab Xeeb Kev Nyab XeebCov. Kev xaiv kom tsim nyog thiab kev siv tau txo qis kev ua haujlwm raug mob (piv txwv li, OSHA qhia txog kev raug mob ko taw nrog cov khau kev nyab xeeb). Cov tub ntiav yuav tsum muaj cov khau khiab raws li cov kev ntsuas pheej hmoo, thaum cov neeg ua haujlwm yuav tsum ua qhov kev tiv thaiv ua ntej dhau kev sib tham.
