1.Dab tsi yog qhov chaw ntawm cov pa luam yeeb?
Los ntawm cov organic coatings: Decomposition tsim cov pa roj carbon monoxide thiab inhalable hais.
Hydrogen fluoride (HF): Yog tias cov txheej txheej yog PVDF (fluorocarbon), nws tsim cov pa roj hydrogen fluoride, uas ua rau cov kab mob ua pa, qhov muag, thiab tawv nqaij. Kev nqus pa ntawm qhov siab tuaj yeem ua rau lub ntsws edema, thiab ntev - raug rau cov concentrations tsawg tuaj yeem ua rau cov pob txha thiab lub paj hlwb puas.
Hydrogen chloride (HCl), hydrogen cyanide (HCN), thiab lwm yam.: Los ntawm chlorine - los yog nitrogen- muaj cov coatings lossis pigments xws li PVC.
Cov pa roj carbon monoxide (CO), ntau yam hydrocarbon tebchaw: Cov khoom ntawm cov khoom tsis tiav combustion ntawm cov organic teeb meem.
Los ntawm hlau plating / substrate:
Zinc oxide fumes: Ua thaum vuam ntawm galvanized nplooj ntawv; Kev nqus pa tuaj yeem ua rau "hlau fume fever" (zoo ib yam li cov tsos mob khaub thuas hnyav).
Hexavalent chromium: Yog hais tias lub substrate los yog stainless hlau muaj chromium, carcinogenic hexavalent chromium tebchaw tej zaum yuav tsim nyob rau hauv high kub.
Manganese, npib tsib xee, thiab lwm yam hlau oxides: Los ntawm vuam rods los yog puag alloys.
Ozone thiab nitrogen oxides: Ua los ntawm cov tshuaj tiv thaiv ntawm vuam arc nrog cua.
2.Yuav tswj qhov chaw li cas?
Ua ntej-kev kho mob: Ua ntej vuam, tshem tawm cov txheej ntau li ntau tau los ntawm thaj chaw ze ntawm qhov vuam. Siv cov txheej txheem lub cev xws li lub tshuab sib tsoo lossis scraper kom huv si tshem tawm cov txheej hauv 20-30mm vojvoog ntawm ob sab ntawm cov vuam kom txog thaum cov hlau substrate raug.
Lwm cov txheej txheem: Xav txog kev siv lwm txoj kev vuam xws li riveting, bolting, los yog structural adhesive bonding kom tsis txhob muaj fume tiam.
Siv cov ntawv hlau tsis muaj coated: Hauv thaj chaw uas qhov vuam tsim nyog thiab kev zoo nkauj tsis yog qhov kev txhawj xeeb tseem ceeb, ncaj qha siv cov ntawv kub tsis muaj coated -dip galvanized lossis aluminized zinc nplooj tuaj yeem txo cov tshuaj lom (tab sis tseem yuav tsum tau kho cov fume).
3.Yuav ua li cas cua thiab ntes ntses?
Localized Exhaust Ventilation (Xav tau):
Mobile Vuam Fume Purifier: Siv cov cuab yeej siv nrog cov cuab yeej nqus tau yooj yim, qhov chaw nqus nqus tau nyob ze li sai tau (feem ntau nyob rau hauv 15-30cm) mus rau qhov chaw vuam, ntes cov pa taws ncaj qha ua ntej lawv diffuse. Lub hauv siab ua haujlwm lim cartridge (piv txwv li, HEPA) lim cov teeb meem, thiab cov pa roj carbon activated adsorbs qee cov pa roj.
Fixed Exhaust System: Sab saum toj lossis sab suction hoods tau nruab rau ntawm qhov chaw ua haujlwm ruaj khov, txuas nrog lub hauv nruab nrab cov plua plav.
General Ventilation:
Hauv kev cob qhia loj, yuav tsum ua kom muaj qhov cua zoo tag nrho, ntxiv rau qhov chaw tso pa tawm hauv zos. Qhib qhov rooj thiab qhov rais, siv cov kiv cua hauv tsev, thiab lwm yam, los txhawb cov huab cua ncig thiab txo cov pa phem tag nrho.
Vuam ntawm cov xim-coated steel coils nyob rau hauv ib puag ncig, qhov chaw tsis zoo (xws li cov tso tsheb hlau luam lossis cov chav tsev) raug txwv nruj, vim nws tuaj yeem ua rau mob hnyav heev.
4.Dab tsi yuav tsum tau ceev faj txog kev tiv thaiv tus kheej?
Kev tiv thaiv ua pa:
Lub tshuab pa uas muaj zog-purifying respirator los yog ib nrab-lub ntsej muag / tag nrho- lub ntsej muag lub ntsej muag nrog cov lim dej ua ke rau cov khoom me me thiab cov pa roj carbon monoxide / acidic yuav tsum tau siv.
Lub ntsej muag plua plav zoo tib yam (xws li N95) tsis muaj txiaj ntsig zoo thiab tsis tuaj yeem lim cov pa roj thiab cov pa hluav taws xob.
Lwm yam kev tiv thaiv:
Cov looj tsom iav tiv thaiv / ntsej muag daim npog ntsej muag: Tiv thaiv kev sib tsoo thiab cov pa phem los ntawm kev raug mob qhov muag.
Nplaim taws-cov khaub ncaws tiv thaiv kab mob thiab cov hnab looj tes vuam: Tiv thaiv tawv nqaij thiab kub hnyiab.
Tshaj tawm - ntxuav kev ua haujlwm: Hloov khaub ncaws, ntxuav lub ntsej muag thiab tes, thiab tsis txhob nqa cov khoom paug tawm ntawm qhov chaw ua haujlwm.
5.Dab tsi yog kev ceev faj rau cov txheej txheem kev nyab xeeb thiab kev tswj xyuas?
Kev Ceeb Toom thiab Kev cob qhia: Muab kev cob qhia tshwj xeeb rau cov neeg ua haujlwm kom paub tseeb tias lawv nkag siab txog cov xwm txheej tshwj xeeb thiab cov txheej txheem xwm txheej ceev uas cuam tshuam nrog cov xim vuam -coated coils.
Tsim Ib Lub Chaw Ceeb Toom: Teeb kab ceeb toom thaum lub sij hawm vuam los tiv thaiv cov neeg ua haujlwm tsis raug cai nkag mus rau thaj chaw fume diffusion.
Kev Saib Xyuas Kev Noj Qab Haus Huv thiab Kev Saib Xyuas Kev Noj Qab Haus Huv: Yog tias ua tau, saib xyuas qhov concentration ntawm cov khoom phom sij hauv huab cua hauv chaw ua haujlwm. Tsim cov ntaub ntawv kev noj qab haus huv ua haujlwm rau cov vuam thiab ua cov kev kuaj mob tsis tu ncua.
Pov tseg pov tseg: Txheej cov khib nyiab tshem tawm thaum sib tsoo yuav tsum tau sau thiab muab pov tseg raws li cov pov tseg pov tseg kom tsis txhob muaj cov pa phem thib ob.
