He aha nā kinoea ʻawaʻawa e hoʻokuʻu ʻia ai ka lole kiʻekiʻe o ka PTFE i ke ahi?

ka lole PTFE kiʻekiʻe ma lalo o nā kūlana hana maʻamau - hiki iā ia ke pale i nā wela mau a hiki i 260 ° C a me nā huakaʻi pōkole i 300 ° C me ka ʻole o ka decomposing. He kūpaʻa Akā i loko o ke ahi, ke ʻoi aku ka mahana ma mua o 400-500 ° C, hoʻomaka ka mea e hoʻoheheʻe thermally. A nā kinoea i hoʻokuʻu ʻia ʻaʻole he uahi maʻamau .

He mea koʻikoʻi ka hoʻomaopopo ʻana i kēia mau pōʻino no ka palekana o ka wahi hana, ka hoʻolālā ʻana i ke ahi, a me ke koho PPE kūpono.

Hana ʻo Aokai PTFE i nā lole i uhi ʻia i ka PTFE. Mālama mākou i ka palekana. Hōʻike kēia alakaʻi i nā kinoea i hoʻokuʻu ʻia, ko lākou ʻona, a pehea e pale ai iā ʻoe iho i kahi kūlana ahi.

ʻO ke kinoea make mua – Hydrogen Fluoride (HF)

Ke ahi ka PTFE, ua haki nā kaula kalapona-fluorine. Hui pū nā ʻātoma fluorine me ka hydrogen mai ka makū a i ʻole nā ​​kumu ʻē aʻe e hana i ka hydrogen fluoride (HF).

Nā waiwai a me nā pōʻino

• He kinoea kala ʻole me ka ʻala ikaika.

• ʻAiʻino loa - hoʻoheheʻe ʻia i ka wai e hana i ka waika hydrofluoric.

• Hoʻopilikia nui a ʻino i ka ʻōpū hanu, ka ʻili, a me nā maka.

• Hiki ke hana i ka edema pulmonary (wai i loko o ka māmā) i nā hihia koʻikoʻi.

• ʻO HF ke kumu nui o nā mea make mai ka PTFE inhalation ahi.

'Ōlelo Aʻo: ʻAʻole ʻawaʻawa wale ka HF ma ka hoʻohu ʻana - hiki i ka hoʻopili ʻana me ka ʻili maʻemaʻe a i ʻole nā ​​maka hiki ke hoʻoulu i ke ahi hoʻōla hohonu. ʻO nā haʻahaʻa haʻahaʻa he mea weliweli.

ʻO ka mea pepehi hāmau - Perfluoroisobutylene (PFIB)

ʻOi aku ka pōʻino ma mua o ka HF, akā ʻaʻole i ʻike nui ʻia, ʻo ia ka perfluoroisobutylene (PFIB).

Nā waiwai a me nā pōʻino

• ʻAʻohe kala a ʻala ʻole - ʻaʻole hiki iā ʻoe ke honi.

• He kinoea ʻawaʻawa loa i hana ʻia mai ka puhi ʻana o ka fluoropolymer.

• ʻO ka toxicity ma kahi o 10 mau manawa o ka phosgene (he mea hoʻohana kaua kemika i hoʻohana ʻia ma WWI).

• Hoʻopilikia ka inhalation i ka alveoli māmā, me ka hoʻopaneʻe nui ʻana i ka edema pulmonary - ʻaʻole hiki ke ʻike ʻia nā hōʻailona no nā hola.

• ʻAʻohe lāʻau lapaʻau kūpono. Kākoʻo ka mālama ʻana (oxygen, mechanical ventilation).

ʻŌlelo aʻo koʻikoʻi: No ka mea ʻaʻohe ʻala o ka PFIB a ua lohi nā hōʻailona, ​​ʻaʻole ʻike paha nā limahana ua ʻike ʻia lākou a hiki i nā hola ma hope, ke ulu nei ka ʻeha hanu. Hana kēia i ka PFIB i mea hoʻopunipuni.

ʻO nā kinoea ʻawaʻawa a me nā ʻāpana ʻē aʻe

Ma waho aʻe o ka HF a me ka PFIB, aia nā mea ʻino ʻē aʻe o ka uahi ahi PTFE:

• ʻO ka carbon monoxide (CO) - mai ka hoʻopau piha ʻole ʻana o nā mea ola. ʻAʻohe kala, ʻala ʻole, pili i ka hemoglobin.

• ʻO nā ʻāpana fluorine maikaʻi - hiki ke hanu hohonu i loko o ka māmā.

• ʻO ke koena o ka waika Perfluorooctanoic (PFOA) - hiki ke hoʻokuʻu i nā mea hoʻoheheʻe koena mai ka hana ʻana o ka PTFE i nā uahi ʻawaʻawa i nā wela kiʻekiʻe (ʻoiai ua hōʻemi ka PTFE hou i ka PFOA).

• E ʻimi i nā dioxins – i ka wā e ʻā ai ka PTFE me nā mea i loko o ka chlorine (e laʻa, ka uwea PVC, kekahi mau uhi), hiki ke hana ʻia nā dibenzo-dioxins polychlorinated a me nā furans.

Nā ʻōlelo aʻoaʻo palekana - He aha e hana ai i kahi ahi PTFE

1. E haʻalele mua. A laila e pale i nā mea pane.

Inā wela ka lole PTFE i ke ahi, ʻo ka hana koʻikoʻi ka pale ʻana i ka uahi . E haʻalele koke i kahi.

2. PPE kūpono - ʻaʻole pono ka uhi ʻana o ka uahi maʻamau

• Pono ʻia: Mea hoʻohāhā paʻa ponoʻī (SCBA) me ka maka piha, hiki ke kānana i nā kinoea waikawa a hāʻawi i ka ea maʻemaʻe.

• No ke aha ʻaʻole he mask maʻamau: ʻAʻole hoʻōki ka N95 maʻamau a i ʻole nā ​​​​mask lapaʻau i ka HF, PFIB, a i ʻole nā ​​​​particulates maikaʻi. ʻAʻole lawa paha nā mea hanu pahu pahu kemika no PFIB.

• Palekana ʻili: E hoʻohana i nā lole pale kino piha a me nā mīkina lima - hiki iā HF ke komo i nā mea maʻamau.

3. Kokua mua a me ka pane kino

• Inā ʻae ʻia ka uahi, e neʻe koke i ka ea hou.

• E ʻimi i ka lāʻau lapaʻau pilikia - mai kali i nā hōʻailona.

• Mea nui: Hiki ke nā hōʻailona pili (mai ka PFIB) lohi i ka hoʻomaka ʻana o a hiki i 24 mau hola. ʻOiai inā maikaʻi ke kanaka i ka wā mua, pono e loiloi ʻia e ke kauka.

• E haʻi aku i nā limahana lapaʻau ua ʻike ʻia ka mea maʻi i nā huahana puhi PTFE - pono ka lāʻau make HF a me PFIB i ka mālama kākoʻo kikoʻī.

ʻO ka ʻōlelo palekana ʻo Aokai PTFE: palekana ka lole PTFE no ka hoʻohana maʻamau a no ka overheating pōkole me ka ʻole decomposition. Pono ke ahi e hana i kēia mau kinoea. Eia naʻe, pono nā hoʻolālā palekana ahi ma nā hale e hoʻohana ana i nā mea PTFE e komo i nā lako SCBA a me ka hoʻomaʻamaʻa ʻana i nā hōʻailona lohi.

Hōʻuluʻulu manaʻo - E ʻike i nā pilikia, e hoʻolālā e like me ia

Nā mea nui e lawe ai:

• Palekana ka lole PTFE ma lalo o ka hoʻohana maʻamau - ʻaʻole ia e decompose ma lalo o 300°C.

• I ke ahi, hoʻokuʻu ia i ka hydrogen fluoride a me ka perfluoroisobutylene (PFIB), nā mea ʻawaʻawa loa.

• Pilikia loa ka PFIB - ʻaʻohe ʻala, ʻaʻohe antidote, nā hōʻailona lohi.

• Mai hoʻohana i nā pale uwahi maʻamau. Pono ka SCBA.

• Ma hope o ka hoʻolaha ʻana, e ʻimi i ka loiloi olakino inā ʻaʻohe hōʻailona koke.

Hāʻawi ʻo Aokai PTFE i nā pepa ʻikepili palekana (SDS) no kā mākou huahana lole PTFE āpau. Manaʻo mākou e nānā nā mea kūʻai aku i nā protocol pane ahi me kā lākou mau hui palekana.

Hāʻawi ʻia ka ʻike ma luna e Jiangsu Aokai New Materials Technology Co., Ltd.

Inā makemake ʻoe e aʻo hou aʻe e pili ana i nā kikoʻī, ka mālama ʻana i ka palekana, a me nā hoʻonā maʻamau no nā lole wela kiʻekiʻe PTFE, nā lipine, nā kāʻei mesh, a me nā mea hou aku:

• Mr. Guo: +86 18944819998

• Mr. Liu: +86 13705266308

ʻO ka pili ʻana i ka philosophy of professionalism a me ka kūpaʻa, ua kūpaʻa mākou i ka hāʻawi ʻana i nā hoʻonā hoʻokahi a me nā lawelawe noʻonoʻo.
