Dab tsi toxic Gases Ua PTFE High-Tub Npuag Tso Tawm Thaum Kub?

PTFE high-temperature npuag yog zoo kawg nkaus ruaj khov nyob rau hauv ib txwm ua hauj lwm tej yam kev mob - nws muaj peev xwm tiv taus kub mus txog 260 ° C thiab luv luv excursions mus rau 300 ° C yam tsis muaj decomposing. Tab sis nyob rau hauv qhov hluav taws kub, thaum kub tshaj 400-500 ° C, cov khoom pib thermally decompose. Thiab cov pa roj tso tawm tsis yog pa luam yeeb.

Kev nkag siab txog cov kev phom sij no yog qhov tseem ceeb rau kev nyab xeeb ntawm chaw ua haujlwm, kev npaj teb hluav taws kub, thiab xaiv PPE kom raug.

Aokai PTFE tsim PTFE-coated fabrics. Peb coj kev nyab xeeb tiag tiag. Phau ntawv qhia no piav qhia txog dab tsi gases raug tso tawm, lawv toxicity, thiab yuav tiv thaiv koj tus kheej li cas thaum muaj hluav taws kub.

Primary Lethal Gas - Hydrogen Fluoride (HF)

Thaum PTFE hlawv, cov carbon-fluorine bonds tawg. Fluorine atoms ua ke nrog hydrogen los ntawm ya raws lossis lwm qhov chaw los tsim hydrogen fluoride (HF).

Khoom thiab phom sij

• Cov roj uas tsis muaj xim nrog lub zog, pungent tsw.

• High corrosive - yaj hauv dej los tsim hydrofluoric acid.

• Heev irritates thiab corrodes lub ua pa ib ntsuj av, daim tawv nqaij, thiab ob lub qhov muag.

• Muaj peev xwm ua rau pulmonary edema (kua kua hauv lub ntsws) thaum mob hnyav.

• HF yog qhov ua rau cov neeg tuag los ntawm PTFE hluav taws inhalation.

Lus Cim: HF tsis yog tsuas yog tshuaj lom los ntawm kev nqus pa - kev sib cuag nrog cov tawv nqaij ntub lossis qhov muag tuaj yeem ua rau mob sib sib zog nqus, kho cov tshuaj tua kab mob. Txawm tias tsawg concentrations yog txaus ntshai.

Cov neeg uas ntsiag to - Perfluoroisobutylene (PFIB)

Kev phom sij ntau dua li HF, tab sis tsis paub zoo, yog perfluoroisobutylene (PFIB).

Khoom thiab phom sij

• Tsis muaj xim thiab tsis muaj ntxhiab - koj tsis tuaj yeem hnov ​​​​nws.

• Cov pa phem heev uas tsim los ntawm fluoropolymer combustion.

• Toxicity yog kwv yees li 10 npaug ntawm phosgene (ib qho tshuaj tua rog siv hauv WWI).

• Kev nqus pa ua rau lub ntsws alveoli, ua rau mob ntsws ntev ntev - cov tsos mob yuav tsis tshwm sim rau ntau teev.

• Tsis muaj tshuaj tiv thaiv zoo. Kev kho mob yog txhawb nqa (oxygen, mechanical ventilation).

Kev ceeb toom tseem ceeb: Vim tias PFIB tsis muaj ntxhiab tsw thiab cov tsos mob qeeb, cov neeg ua haujlwm yuav tsis paub tias lawv tau raug mob mus txog rau teev tom qab, thaum muaj mob ua pa hnyav. Qhov no ua rau PFIB tshwj xeeb yog insidious.

Lwm cov pa phem thiab cov pa phem

Ntxiv nrog rau HF thiab PFIB, PTFE cov pa taws muaj lwm yam teeb meem:

• Cov pa roj carbon monoxide (CO) - los ntawm kev ua tsis tiav ntawm cov khoom siv organic. Tsis muaj xim, tsis muaj ntxhiab, khi rau hemoglobin.

• Fine fluorine-muaj cov khoom xyaw - tuaj yeem nqus tau tob rau hauv lub ntsws.

• Perfluorooctanoic acid (PFOA) residues - residual surfactants los ntawm PTFE manufacturing tej zaum yuav tso cov pa phem ntawm qhov kub thiab txias (txawm tias niaj hnub PTFE tau txo PFOA).

• Cov kab mob dioxins - thaum PTFE hlawv ua ke nrog cov khoom siv chlorine (xws li, PVC thaiv, qee cov coatings), polychlorinated dibenzo-dioxins thiab furans tuaj yeem tsim.

Kev Ceeb Toom Txog Kev Nyab Xeeb - Yuav Ua Li Cas Hauv Hluav Taws Xob PTFE

1. Ua ntej khiav tawm. Tom qab ntawd tiv thaiv cov neeg teb.

Yog tias PTFE cov ntaub ntawv kub kub ntes hluav taws, qhov tseem ceeb tshaj plaws yog kom tsis txhob nqus cov pa taws . Tshem tawm thaj chaw tam sim ntawd.

2. Raws li PPE - qhov ncauj qhov ntswg zoo tib yam tsis muaj txiaj ntsig

• Yuav tsum tau: Lub tshuab ua pa ntawm tus kheej (SCBA) nrog lub ntsej muag puv, muaj peev xwm lim cov kua qaub thiab muab cua huv.

• Vim li cas ho tsis yog lub npog ntsej muag zoo tib yam: Standard N95 lossis lub ntsej muag phais tsis txwv HF, PFIB, lossis cov khoom zoo. Txawm tias cov tshuaj tua kab mob ua pa yuav tsis tsim nyog rau PFIB.

• Kev tiv thaiv daim tawv nqaij: Siv cov khaub ncaws tiv thaiv lub cev thiab hnab looj tes - HF tuaj yeem nkag mus rau cov ntaub ntawv zoo tib yam.

3. Kev pab thawj zaug thiab kev kho mob teb

• Yog tias fumes raug nqus, txav tam sim ntawd mus rau huab cua ntshiab.

• Nrhiav kev kho mob xwm txheej ceev - tsis txhob tos kom pom cov tsos mob.

• Tseem ceeb: Cov tsos mob ntsig txog (tshwj xeeb tshaj yog los ntawm PFIB) yuav muaj qhov pib qeeb txog li 24 teev. Txawm hais tias tus neeg xav tias zoo thaum xub thawj, lawv yuav tsum tau soj ntsuam los ntawm tus kws kho mob.

• Qhia rau cov neeg ua haujlwm kho mob tias tus neeg mob tau raug PTFE combustion khoom - HF thiab PFIB tshuaj lom yuav tsum tau saib xyuas tshwj xeeb.

Aokai PTFE nqe lus hais txog kev nyab xeeb: PTFE npuag muaj kev nyab xeeb rau kev siv ib txwm thiab txawm tias luv luv overheating yam tsis muaj decomposition. Hluav taws yuav tsum tau tsim cov pa roj. Txawm li cas los xij, cov phiaj xwm kev nyab xeeb hluav taws hauv cov chaw siv PTFE cov ntaub ntawv yuav tsum suav nrog SCBA cov cuab yeej thiab kev cob qhia txog cov tsos mob qeeb.

Summary - Paub qhov txaus ntshai, Npaj raws li

Cov ntsiab lus tseem ceeb:

• PTFE npuag muaj kev nyab xeeb nyob rau hauv ib txwm siv - nws tsis decompose hauv qab 300 ° C.

• Hauv hluav taws, nws tso tawm hydrogen fluoride thiab perfluoroisobutylene (PFIB), ob qho tib si muaj tshuaj lom heev.

• PFIB yog qhov txaus ntshai tshwj xeeb - tsis muaj ntxhiab, tsis muaj tshuaj tua kab mob, cov tsos mob qeeb.

• Tsis txhob siv daim npog qhov ncauj qhov ntswg. Yuav tsum muaj SCBA.

• Tom qab kis tus kab mob, nrhiav kev kho mob txawm tias tsis muaj tsos mob tam sim ntawd.
