Nyob zoo cov phooj ywg welder, kev ua haujlwm vuam hluav taws xob uas koj tau koom nrog yuav cuam tshuam cov pa luam yeeb hlau, phom sij roj, thiab hluav taws xob hluav taws xob teeb meem thaum koj ua haujlwm. Kuv yuav tsum qhia koj txog yam xwm txheej txaus ntshai thiab kev tiv thaiv!
Xinfa vuam cov cuab yeej muaj cov yam ntxwv zoo thiab tus nqi qis. Yog xav paub ntxiv, thov mus saib:Vuam & txiav Manufacturers - Tuam Tshoj Vuam & Txiav Hoobkas & lwm tus neeg (xinfatools.com)
1. Kev ua haujlwm txaus ntshai ntawm kev siv hluav taws xob vuam
(1) Kev phom sij ntawm cov pa luam yeeb hlau:
Qhov muaj pes tsawg leeg ntawm vuam fume txawv nyob ntawm seb hom vuam qws siv. Thaum lub sij hawm welding, lub arc paug generates kub ntawm 4000 txog 6000 ° C. Thaum melting lub vuam pas nrig thiab vuam, cov pa luam yeeb ntau yog tsim, uas yog tsim los ntawm hlau oxide, manganese oxide, silica, silicate, thiab lwm yam. Cov pa luam yeeb permeate hauv qhov chaw ua haujlwm, nws yooj yim rau nqus tau pa. rau hauv lub ntsws.
Kev nqus tau mus ntev tuaj yeem ua rau mob fibrous hauv lub ntsws cov ntaub so ntswg, uas yog hu ua welder's pneumoconiosis, thiab feem ntau nrog cov teeb meem xws li manganese lom, fluorosis thiab hlau fume fever.
Cov neeg mob feem ntau muaj cov tsos mob ua pa xws li mob hauv siab, mob hauv siab, ua tsis taus pa, thiab hnoos, nrog rau mob taub hau, tsis muaj zog thiab lwm yam tsos mob. Lub ntsws qi ua haujlwm kuj raug puas tsuaj rau qee yam.
(2) Kev phom sij ntawm cov pa phem:
Nyob rau hauv qhov kev txiav txim siab kub thiab muaj zog ultraviolet rays tsim los ntawm vuam arc, ntau cov pa phem, xws li nitrogen oxides, carbon monoxide, ozone, thiab lwm yam, yuav raug tsim nyob ib ncig ntawm thaj tsam arc.
Thaum cov hemoglobin ntau ua ke nrog cov pa roj carbon monoxide, oxygen poob lub sijhawm los ua ke nrog hemoglobin, ua rau muaj kev cuam tshuam rau lub cev lub peev xwm thauj thiab siv oxygen, ua rau tib neeg cov ntaub so ntswg tuag vim tsis muaj oxygen.
(3) Kev phom sij ntawm arc hluav taws xob:
Lub teeb arc tsim los ntawm vuam feem ntau suav nrog rays infrared, pom lub teeb thiab ultraviolet rays. Ntawm lawv, ultraviolet rays ua mob rau tib neeg lub cev tsuas yog los ntawm cov teebmeem photochemical. Nws ua rau lub qhov muag thiab cov tawv nqaij raug mob, ua rau keratoconjunctivitis (photoophthalmia) thiab daim tawv nqaij biliary erythema.
Cov tsos mob tseem ceeb muaj xws li mob qhov muag, kua muag, daim tawv muag liab thiab spasm. Tom qab raug ultraviolet rays, daim tawv nqaij yuav tshwm edematous erythema nrog cov ciam teb ntshiab. Hauv cov xwm txheej hnyav, hlwv, exudate thiab edema tuaj yeem tshwm sim, nrog rau qhov pom tseeb ntawm qhov kub hnyiab.
2. Kev phom sij ntawm hluav taws xob vuam
1. Cov neeg uas tau koom nrog kev siv hluav taws xob rau lub sijhawm ntev yuav muaj kev pheej hmoo ntau dua ntawm kev kis tus kab mob pneumoconiosis.
2. Cov pa phem tuaj yeem nqus tau thaum lub sijhawm ua haujlwm, ua rau tib neeg noj qab haus huv thiab txawm lub neej.
3. Kev siv hluav taws xob vuam tau yooj yim ua rau keratoconjunctivitis (electrophotoophthalmia) thiab daim tawv nqaij biliary erythema.
3. Ceev faj
(1) Txhim kho vuam tshuab thiab txhim kho cov txheej txheem vuam thiab cov khoom siv
Los ntawm kev txhim kho vuam tshuab, peb tuaj yeem txo qhov kev puas tsuaj rau tib neeg lub cev los ntawm kev ua haujlwm vuam. Txij li feem ntau ntawm cov teeb meem tshwm sim los ntawm kev vuam yog cuam tshuam nrog cov txheej txheem ntawm cov txheej txheem electrode, xaiv cov hlau tsis muaj tshuaj lom lossis tsis muaj tshuaj lom welding electrodes kuj yog ib qho kev ntsuas zoo los txo cov kev phom sij ntawm vuam.
(2) Txhim kho qhov cua ntawm qhov chaw ua haujlwm
Txoj kev tso cua tuaj yeem muab faib ua qhov cua thiab cua tshuab cua. Mechanical ventilation cia siab rau lub siab tsim los ntawm cov kiv cua los pauv huab cua. Nws muaj kev tshem tawm plua plav zoo dua thiab ua kom muaj detoxification. Yog li ntawd, nws yuav tsum tau siv thaum vuam nyob rau hauv tsev los yog kaw qhov chaw uas tsis zoo ntuj cua. Mechanical cua ntsuas ntsuas.
(3) Txhim khu kev tiv thaiv tus kheej
Kev tiv thaiv tus kheej muaj zog tuaj yeem tiv thaiv kev puas tsuaj ntawm cov pa roj carbon monoxide thiab plua plav tsim thaum lub sijhawm vuam. Cov neeg ua haujlwm yuav tsum siv cov iav tiv thaiv tsim nyog, daim npog ntsej muag, daim npog qhov ncauj, hnab looj tes, khaub ncaws tiv thaiv dawb, thiab khau khiab. Lawv yuav tsum tsis txhob hnav khaub ncaws luv luv lossis lub tes tsho rolled. Yog tias ua haujlwm hauv lub thawv kaw nrog qhov cua tsis zoo, lawv yuav tsum hnav khaub ncaws tiv thaiv. Lub kaus mom hlau tiv thaiv nrog kev ua haujlwm ntawm huab cua.
(4) Txhim khu kev tiv thaiv kev ua haujlwm tshaj tawm thiab kev kawm ua haujlwm
Cov neeg ua haujlwm vuam yuav tsum tau kawm paub txog kev nyab xeeb ntawm kev ua haujlwm thiab kev paub txog kev noj qab haus huv los txhim kho lawv txoj kev paub txog kev tiv thaiv tus kheej thiab txo qis kev ua haujlwm. Nyob rau tib lub sijhawm, peb tseem yuav tsum ntxiv dag zog rau kev saib xyuas cov plua plav phom sij hauv cov chaw ua haujlwm vuam thiab kev kuaj lub cev ntawm cov welder kom pom thiab daws cov teeb meem raws sijhawm.
