Imaphi Amagesi Anobuthi Ekhishwa Indwangu Ye-PTFE Esezingeni Eliphezulu Uma Isha?

Indwangu ye-PTFE enezinga eliphezulu lokushisa izinze ngokuphawulekayo ngaphansi kwezimo ezivamile zokusebenza – ingamelana namazinga okushisa aqhubekayo afika ku-260°C kanye nohambo olufushane ukuya ku-300°C ngaphandle kokubola. Kodwa emlilweni, lapho izinga lokushisa lidlula i-400-500 ° C, izinto ziqala ukubola ngokushisa. Futhi amagesi akhishwayo awawona umusi ovamile.

Ukuqonda lezi zingozi kubalulekile ekuphepheni kwendawo yokusebenza, ukuhlela impendulo yomlilo, nokukhetha okufanele kwe-PPE.

I-Aokai PTFE yenza izindwangu eziboshwe nge-PTFE. Ukuphepha sikuthatha njengento ebalulekile. Lo mhlahlandlela uchaza ukuthi yimaphi amagesi akhululwayo, ubuthi bawo, nokuthi ungazivikela kanjani esimweni somlilo.

I-Primary Lethal Gas – Hydrogen Fluoride (HF)

Uma i-PTFE isha, ibhondi ye-carbon-fluorine iyaphuka. Ama-athomu e-fluorine ahlangana ne-hydrogen asuka kumswakama noma eminye imithombo yakhe i- hydrogen fluoride (HF).

Izakhiwo kanye nezingozi

• Igesi engenambala enephunga elinamandla, eliphunga.

• Igqwala kakhulu - incibilika emanzini yenze i-hydrofluoric acid.

• Icasula kakhulu futhi idle umgudu wokuphefumula, isikhumba, namehlo.

• Ingabangela i-pulmonary edema (uketshezi olusemaphashini) ezimeni ezinzima.

• I-HF iyimbangela ehamba phambili yokushona kwabantu ngenxa yokuhogela umlilo kwe-PTFE.

Qaphela: I-HF ayiyona nje ubuthi ngokuhogela - ukuthinta isikhumba esimanzi noma amehlo kungabangela ukusha kwamakhemikhali okujulile, okuphola kancane. Ngisho nokugxila kancane kuyingozi.

The Silent Killer – Perfluoroisobutylene (PFIB)

Iyingozi kakhulu kune-HF, kodwa engaziwa kangako, i- perfluoroisobutylene (PFIB).

Izakhiwo kanye nezingozi

• Ayinambala futhi ayinaphunga - awukwazi ukuyihogela.

• Igesi enobuthi obuphezulu ekhiqizwe ngokuqondile ekushisweni kwe-fluoropolymer.

• Ubuthi bucishe buphindwe ka-10 kune-phosgene (i-agent yempi yamakhemikhali esetshenziswa ku-WWI).

• Ukuhogela umoya kulimaza i-alveoli yamaphaphu, kubangele ukubambezeleka okukhulu kwe-pulmonary edema - izimpawu zingase zingabonakali amahora amaningi.

• Alikho ikhambi elisebenzayo elikhona. Ukwelashwa kuyasekela (umoya-mpilo, umoya wokungena ngomshini).

Isexwayiso esibalulekile: Ngenxa yokuthi i-PFIB ayinaphunga futhi izimpawu ziyabambezeleka, abasebenzi bangase bangaboni ukuthi baye badalulwa kuze kube ngemva kwamahora amaningi, lapho kuvela ukucindezeleka okukhulu kokuphefumula. Lokhu kwenza i-PFIB ibe nobuqili ikakhulukazi.

Amanye Amagesi Anobuthi Nezinhlayiya

Ngaphezu kwe-HF ne-PFIB, intuthu yomlilo ye-PTFE iqukethe ezinye izinto eziyingozi:

• I-Carbon monoxide (CO) - kusuka ekushisweni okungaphelele kwanoma iyiphi into ephilayo. Ayinambala, ayinaphunga, ibopha ku-hemoglobin.

• Izinhlayiya ezinhle ezine-fluorine - zingadonselwa ekujuleni kwamaphaphu.

• Izinsalela ze-Perfluorooctanoic acid (PFOA) - izinsalela ezisasele eziphuma ekwenziweni kwe-PTFE zingakhipha intuthu enobuthi emazingeni okushisa aphezulu (nakuba i-PTFE yesimanje yehlise i-PFOA).

• Landelela ama-dioxins – uma i-PTFE isha kanye nezinto eziqukethe i-chlorine (isb., izintambo ze-PVC, okokunamathela okuthile), ama-dioxin ane-polychlorine nama-furan angase akhiqizwe.

Izexwayiso Zokuphepha - Okufanele Ukwenze Emlilweni we-PTFE

1. Phuma kuqala. Bese uvikela abaphenduli.

Uma indwangu ye-PTFE eshisa kakhulu ishisa, isenzo esibaluleke kakhulu ukugwema ukuhogela intuthu . Phuma endaweni ngokushesha.

2. I-PPE efanele - imaski yentuthu evamile ayinamsebenzi

• Kuyadingeka: Imishini yokuphefumula ezimele (SCBA) enobuso obugcwele, ekwazi ukuhlunga amagesi aneasidi futhi inikeze umoya ohlanzekile.

• Kungani kungeyona imaski evamile: I -N95 ejwayelekile noma imaski yokuhlinzwa ayivimbi i-HF, PFIB, noma izinhlayiya ezinhle. Ngisho nama-cartridge respirators amakhemikhali angase anganeli i-PFIB.

• Ukuvikelwa kwesikhumba: Sebenzisa izingubo zokuzivikela ezigcwele umzimba wonke namagilavu ​​- i-HF ingangena ezintweni ezijwayelekile.

3. Usizo lokuqala kanye nempendulo yezokwelashwa

• Uma intuthu ihogelwe ngephutha, hambisa ngokushesha emoyeni omusha.

• Funa ukwelashwa okuphuthumayo - ungalindi izimpawu.

• Okubalulekile: Izimpawu ezihlobene (ikakhulukazi ezivela ku-PFIB) zingase zibe nokubambezeleka kokuqala kwamahora angu-24. Ngisho noma umuntu ezizwa ephilile ekuqaleni, kufanele ahlolwe ngudokotela.

• Yazisa abasebenzi bezokwelapha ukuthi isiguli sachayeka emikhiqizweni evuthayo ye-PTFE - Ubuthi be-HF kanye ne-PFIB budinga ukunakekelwa okukhethekile okusekelayo.

Isitatimende sokuphepha se-Aokai PTFE: Indwangu ye-PTFE iphephile ukuthi isetshenziswe okuvamile futhi ngisho nokushisa okufushane ngaphandle kokubola. Kudingeka umlilo ukuze kukhiqizwe la magesi. Kodwa-ke, izinhlelo zokuphepha komlilo ezikhungweni ezisebenzisa izinto ze-PTFE kufanele zifake imishini ye-SCBA nokuqeqeshwa ngezimpawu ezibambezelekile.

Isifingqo - Yazi Izingozi, Hlela Ngokufanele

Okuthathwayo okubalulekile:

• Indwangu ye-PTFE iphephile ngaphansi kokusetshenziswa okuvamile – ayiboli ngaphansi kuka-300°C.

• Emlilweni, ikhipha i-hydrogen fluoride ne- perfluoroisobutylene (PFIB), zombili ezinobuthi obukhulu.

• I-PFIB iyingozi kakhulu - ayinaphunga, ayinalo ikhambi, izimpawu ezibambezelekile.

• Ungalokothi usebenzise imaski yentuthu evamile. I-SCBA iyadingeka.

• Ngemva kokuchayeka, funa ukuhlolwa kwezokwelapha ngisho noma zingekho izimpawu ezisheshayo.

I-Aokai PTFE inikeza amashidi edatha yokuphepha (SDS) kuyo yonke imikhiqizo yethu yendwangu ye-PTFE. Sincoma ukuthi amakhasimende abuyekeze izivumelwano zokuphendula umlilo namathimba awo okuphepha.
