Raws li kev txheeb cais ntawm BureauofLabor ntawm Tebchaws Meskas: kev tiv thaiv ko taw thiab ceg: 66% ntawm cov neeg ua haujlwm raug mob ceg tsis hnav khau kev nyab xeeb, khau tiv thaiv, 33% hnav khau xws li, thiab 85% ntawm cov neeg ua haujlwm raug mob tsis muaj kev tiv thaiv vim cov khoom. ntaus. Ib feem ntawm khau raj. Txhawm rau tiv thaiv ob txhais ceg los ntawm kev puas tsuaj los ntawm cov khoom ntog, dov, cov khoom ntse, cov hlau molten, qhov chaw kub, thiab cov nplais nplaum, cov neeg ua haujlwm yuav tsum siv cov hlua khi kom tsim nyog, khau ruaj ntseg, lossis khau khiab lossis leggings.
Thaum xaiv cov khau kev nyab xeeb, koj tuaj yeem ua raws li 5 cov ntsiab lus hauv qab no:
A. Ntxiv rau qhov tsim nyog cov khau tiv thaiv, nws tseem yuav tsum tau ua kom haum rau ko taw thiab hnav kom haum rau tib neeg. Nws yog ib qho tseem ceeb heev uas yuav tau ua tib zoo xaiv cov khau loj uas tsim nyog.
B. Cov khau tiv thaiv yuav tsum muaj cov qauv tsim tsis yog khaus khaus, tsis yog tsuas yog tiv thaiv tib neeg ko taw los ntawm kev raug mob, tab sis kuj tiv thaiv kev raug mob los ntawm tus neeg teb xov tooj tau swb.
C. Ntau yam khau tiv thaiv nrog kev ua yeeb yam sib txawv yuav tsum ua kom tau raws li cov kev qhia ntawm lawv qhov kev tiv thaiv kev ua tau zoo, xws li cov ntiv taw tsis nkig, ob txhais taw tsis stabbed, thiab yuav tsum muaj kev rwb thaiv tsev. Tab sis kev nyab xeeb khau tsis yog txhua yam.
D. Ua ntej siv cov khau tiv thaiv, ua tib zoo tshuaj xyuas lossis sim. Hauv kev ua haujlwm hluav taws xob thiab kua qaub, cov khau tiv thaiv puas thiab tawg yog qhov txaus ntshai.
E. Cov khau tiv thaiv yuav tsum khaws cia kom zoo tom qab siv. Cov khau roj hmab yuav tsum tau muab yaug nrog dej lossis tshuaj tua kab mob thiab ziab kom ntev lub neej kev pab cuam. Ib qho ntawm cov khau kev nyab xeeb feem ntau yog molded los ntawm cov khoom siv polyurethane, uas muaj qhov zoo ntawm acid thiab alkali tsis kam, dej tsis kam, roj tsis kam, rwb thaiv tsev, hnav tsis kam thiab lub teeb yuag. 3 zaug hnav resistant dua li cov roj hmab zoo tib yam. Nws yog mos thiab lub teeb, thiab hnyav tsuas yog 50% -60% ntawm cov roj hmab ib leeg. Cov khau kev nyab xeeb sib txawv muaj cov ntawv thov sib txawv thiab cov haujlwm sib txawv: kev nyab xeeb ntawm cov khau tiv thaiv ntiv taw yog AN1, haum rau kev thauj khoom thiab tshem tawm, mining, roj av, quarrying, metallurgy, chaw nres nkoj, machinery, kev tsim kho, hav zoov, tshuaj lom neeg kev lag luam, thiab lwm yam. Cov khau khiab-pov thawj kev nyab xeeb muaj kev sib tsoo ntawm qib 1 thiab tsim nyog rau kev khawb av, tiv thaiv hluav taws, kev tsim kho, hav zoov, ua haujlwm txias, tshuab thiab lwm yam. Cov khau hluav taws xob tiv thaiv kev nyab xeeb yog tsim rau cov neeg siv hluav taws xob, cov neeg siv hluav taws xob, cable installers, substation installers, thiab lwm yam Lus Cim: Haum rau kev ua haujlwm ib puag ncig nrog lub zog zaus qis dua 1KV, qhov chaw ua haujlwm yuav tsum ua kom lub siab qhuav. Tsis txhob sib cuag nrog cov khoom ntse, qhov kub thiab txias thiab cov khoom corrosive, thiab hauv qab yuav tsum tsis txhob corroded thiab puas. Anti-static kev nyab xeeb khau tuaj yeem tshem tawm cov hluav taws xob zoo li qub hauv tib neeg lub cev thiab tsim nyog siv rau hauv cov chaw ua haujlwm flammable, xws li cov chaw nres tsheb roj thiab cov neeg ua haujlwm roj liquefied.
Lus Cim: Nws yog txwv tsis pub siv cov khau insulated; hnav cov khau tiv thaiv zoo li qub yuav tsum tsis txhob hnav cov ntaub qhwv cov ntaub so ntswg los yog siv cov insulated insoles tib lub sijhawm; khau tiv thaiv zoo li qub yuav tsum tau siv ua ke nrog cov khaub ncaws tiv thaiv zoo li qub; Cov khau tiv thaiv zoo li qub yuav tsum tsis txhob siv ntau tshaj 200 teev. Tus nqi khau kuj raug kuaj ib zaug. Yog tias qhov kev tiv thaiv tsis nyob hauv qhov kev teev tseg, nws tsis tuaj yeem siv los ua cov khau tiv thaiv zoo li qub. Acid thiab alkali resistant nkawm khau yog haum rau cov neeg ua haujlwm electroplating, acid pickers, electrolysis neeg ua hauj lwm, distributors ua kua, tshuaj neeg ua hauj lwm, thiab lwm yam Lus Cim: Acid thiab alkali resistant khau tsuas yog siv rau hauv cov kua qaub thiab alkali ua hauj lwm qhov chaw uas tsis muaj concentration; zam kev sib cuag nrog qhov kub thiab txias, kev puas tsuaj rau lub sab sauv lossis ib qho to; Siv dej los ntxuav cov kua qaub thiab alkali ntawm cov khau tom qab hnav, ces Cia kom qhuav thiab tsis txhob raug tshav ntuj ncaj qha lossis ziab.
Ua ntej xaiv, peb yuav tsum xub nkag siab txog cov teeb meem tseem ceeb uas ua rau raug mob ncaj qha lossis tsis ncaj rau cov neeg ua haujlwm ko taw. Muaj 6 yam hauv qab no:
A. Kov los ntawm ib qho nyuaj, dov lossis ntog.
B. Txhaum ib leeg lossis lub cev ntawm khau los ntawm cov khoom ntse.
C. Txiav los ntawm cov khoom ntse thiab txawm ua rau daim tawv nqaij.
D. Qhov chaw yog lubricated thiab ntog.
E. Sib cuag nrog cov tshuaj, molten hlau, kub thiab kub tsis tshua muaj qhov chaw.
F. Ua haujlwm nyob rau hauv ib puag ncig uas muaj cov pa taws kub hnyiab. Yog tias qhov kev tso tawm hluav taws xob zoo li qub tsis tsim nyog, nws yuav dhau los ua qhov hluav taws kub txhua lub sijhawm, ua rau tawg. Kev xaiv zoo ntawm nkawm khau kev nyab xeeb tuaj yeem ntsuas thiab xaiv los ntawm cov qauv ntawm cov khau:
A, hom khau: uas yog, qhov ntev thiab dav ntawm cov qauv khau, qhov dav ntawm lub cev khau yog nruj nrog ko taw.
B. Sab saum toj: Seb lub softness ntawm tawv yuav yog ntuj thiab haum thaum taug kev.
C, khau lub xeev: Txawm tias tag nrho cov khau lub xeev tuaj yeem lo rau ntawm ko taw yam tsis tau tsoo ko taw, xoob thiab tsis tawm, hloov tau.
D, khau lub cev: tawv tawv, tawv tawv, PVC thiab hluavtaws fiber ntau.
Cov ntaub ntawv no muaj lawv tus kheej zoo. Piv txwv li, lub cev tawv yog ntau ruaj thiab hnav, thiab nws yooj yim dua hnav, tab sis kev ua haujlwm ntawm kev tiv thaiv corrosive kua tsis zoo. Faux tawv tuaj yeem siv rau hauv cov ntaub ntawv ntawm cov dej tsis zoo, cov tshuaj corrosive lossis lwm yam kab mob, tab sis nws txoj haujlwm raug cuam tshuam yog tias nws ntog tawm ... PVC yog qhov tsim nyog rau kev siv hauv qhov chaw ntub dej thiab kuj yooj yim los ntxuav. Tab sis nws tuaj yeem tawg los ntawm qee cov tshuaj.
E, ntiv taw cap: Lub hau ntiv taw ntawm cov khau kev nyab xeeb yog nruab nrog lub hau steel, lub luag haujlwm tseem ceeb yog tiv thaiv cov ntiv taw kom tsis txhob raug mob lossis raug tsoo. Yog tias cov neeg ua haujlwm yuav tsum ua haujlwm hnyav dua, xws li cov neeg ua haujlwm tsim kho lossis cov neeg ua haujlwm nqa cov khoom hnyav, cov khau kev nyab xeeb thiab lub kaus mom hlau yuav tsum tau ua los ntawm corrosion-resistant thiab 200-joule (J) cuam tshuam.
F, sab hauv ncoo: Seb yog siv cov kev vibration-activating muaj nuj nqi, hws-absorbing muaj nuj nqi, massage muaj nuj nqi, kev kho mob muaj nuj nqi qauv.
G, Neri: Txawm hais tias siv qhov cua kom raug, tsis muaj dej, ua kom sov, cov khoom siv ua haujlwm zoo ib puag ncig.
H, ib leeg: Cov khoom siv feem ntau yog cov roj hmab, roj hmab vulcanized, lossis polyvinyl chloride. Cov pob qij txha feem ntau yog resistant rau abrasion, tshuaj corrosion, rwb thaiv tsev kub thiab roj. Txawm li cas los xij, vim muaj cov yam ntxwv sib txawv ntawm cov khoom siv, kev ua haujlwm kuj txawv. Ib leeg ntawm cov khau kev nyab xeeb yog haum nrog cov ntawv hlau, uas yog siv los tiv thaiv ib leeg los ntawm kev tho los yog tawv. Ntxiv nrog rau kev siv cov roj hmab uas tsis yog-slip, tus qauv tsim ntawm ib leeg kuj tseem ceeb rau kev ua haujlwm tiv thaiv plam. Cov khauj khaum yog tsim los rau hauv cheeb tsam thiab ntau qhov chaw. Cov substrate thiab anti-slip yuav tsum tau siv nyob rau hauv txawv degrees. Piv txwv li, ib puag ncig yog qhov tsis muaj plam, thiab lub teeb yuag substrate yog siv. Sab nraum qhov chaw ib puag ncig yog ntxiv dag zog nrog kev tiv thaiv plam, hnav-tiv taus substrate thiab tuaj yeem tiv taus qhov chaw hnyav. Subdivided rau hauv: dawb-dab tshos, xiav-dab tshos, nyiaj ua haujlwm, kev lag luam kev lag luam, lub teeb kev lag luam, kev lag luam hnyav, kev tsim kho qhov chaw, tourism, kev lag luam kev pabcuam, thiab lwm yam.
