Nibihe Byuka Byangiza PTFE Imyenda Yubushyuhe Bwinshi Irekura Iyo Yaka?

Imyenda yubushyuhe bwa PTFE ihagaze neza cyane mubikorwa bisanzwe - irashobora kwihanganira ubushyuhe bukomeza bugera kuri 260 ° C hamwe ningendo ngufi kuri 300 ° C bitangirika. Ariko mu muriro, iyo ubushyuhe burenze 400-500 ° C, ibintu bitangira kubora. Kandi imyuka irekuwe ntabwo ari umwotsi usanzwe.

Gusobanukirwa nibi byago nibyingenzi kumutekano wakazi, gutegura igenamigambi ryumuriro, no guhitamo neza PPE.

Aokai PTFE ikora imyenda isize PTFE. Dufatana uburemere umutekano. Aka gatabo gasobanura imyuka irekurwa, uburozi bwayo, nuburyo wakwirinda mugihe cyumuriro.

Gazi Yambere Yica - Hydrogen Fluoride (HF)

Iyo PTFE yaka, karubone-fluor iracika. Atome ya Fluorine ihuza hydrogène iva mu butumburuke cyangwa andi masoko kugirango ikore fluoride hydrogène (HF).

Ibyiza n'ingaruka

• Gazi itagira ibara ifite impumuro ikomeye, ikaze.

• Kubora cyane - gushonga mumazi kugirango acide hydrofluoric.

• Birakaza cyane kandi bikonona inzira z'ubuhumekero, uruhu, n'amaso.

• Irashobora gutera ibihaha (fluid mu bihaha) mugihe gikomeye.

• HF niyo mpamvu nyamukuru itera impfu zatewe no guhumeka umuriro wa PTFE.

Icyitonderwa: HF ntabwo ari uburozi gusa muguhumeka - guhura nuruhu rwinshi cyangwa amaso birashobora gutera imiti yimbitse, ikiza buhoro. Ndetse no kwibanda cyane ni bibi.

Umwicanyi Wicecekeye - Perfluoroisobutylene (PFIB)

Ibyago byinshi kuruta HF, ariko ntibizwi cyane, ni perfluoroisobutylene (PFIB).

Ibyiza n'ingaruka

• Ibara ritagira impumuro nziza - ntushobora kunuka.

• Gazi ifite ubumara bukabije buturuka cyane cyane kuri fluoropolymer.

• Uburozi bukubye inshuro 10 ubwa fosgene (imiti yintambara ikoreshwa muri WWI).

• Guhumeka byangiza ibihaha alveoli, bigatera gutinda cyane ibihaha - ibimenyetso ntibishobora kugaragara kumasaha.

• Nta muti mwiza uhari. Umuti urashyigikiwe (ogisijeni, imashini ihumeka).

Umuburo w'ingenzi: Kubera ko PFIB idafite impumuro kandi ibimenyetso biratinda, abakozi ntibashobora kumenya ko byagaragaye nyuma yamasaha, mugihe habaye ibibazo bikomeye byubuhumekero. Ibi bituma PFIB yibeshya cyane.

Ibindi byuka byuburozi kandi byihariye

Usibye HF na PFIB, umwotsi wumuriro wa PTFE urimo ibindi bintu byangiza:

• Umwuka wa karubone (CO) - uhereye ku gutwikwa kutuzuye kw'ibintu byose kama. Ibara ritagira ibara, ridafite impumuro nziza, rihuza na hemoglobine.

• Ibice byiza bya fluor birimo - bishobora guhumeka cyane mubihaha.

• Acide ya Perfluorooctanoic (PFOA) - ibisigisigi bisigaye biva mu nganda za PTFE birashobora kurekura imyotsi y’ubumara ku bushyuhe bwinshi (nubwo PTFE igezweho yagabanije PFOA).

• Kurikirana dioxyyine - mugihe PTFE yaka hamwe nibikoresho birimo chlorine (urugero, insinga za PVC, ibifuniko bimwe), dibenzo-dioxyyine ya polychlorine na furans birashobora kubyara.

Iburira ry'umutekano - Icyo gukora mumuriro wa PTFE

1. Banza wimuke. Noneho urinde abasubiza.

Niba imyenda ya PTFE yubushyuhe bwo hejuru ifashe umuriro, igikorwa cyingenzi nukwirinda guhumeka umwotsi . Hunga ako kanya ako kanya.

2. PPE ikwiye - masike yumwotsi isanzwe ntacyo imaze

• Ibisabwa: Ibikoresho byo guhumeka byonyine (SCBA) bifite isura yuzuye, ishoboye gushungura imyuka ya acide no gutanga umwuka mwiza.

• Kuki utaba mask isanzwe: N95 isanzwe cyangwa masike yo kubaga ntibihagarika HF, PFIB, cyangwa uduce twiza. Ndetse imiti yubuhumekero ya karitsiye ntishobora kuba ihagije kuri PFIB.

• Kurinda uruhu: Koresha imyenda irinda umubiri wose hamwe na gants - HF irashobora kwinjira mubikoresho bisanzwe.

3. Imfashanyo yambere nigisubizo cyubuvuzi

• Niba imyotsi ihumeka kubwimpanuka, hita wimuka uhumeka neza.

• Shakisha ubuvuzi bwihutirwa - ntutegereze ibimenyetso.

• Icyangombwa: Ibimenyetso bifitanye isano (cyane cyane kuva muri PFIB) birashobora kugira gutinda gutangira amasaha 24. Nubwo umuntu yumva ameze neza mu ntangiriro, agomba gusuzumwa na muganga.

• Menyesha abakozi b'ubuvuzi ko umurwayi yahuye n'ibicuruzwa byaka PTFE - Uburozi bwa HF na PFIB busaba ubuvuzi bwihariye.

Aokai PTFE itangazo ryumutekano: Umwenda wa PTFE ufite umutekano kugirango ukoreshwe bisanzwe ndetse no gushyuha mugihe gito utabora. Umuriro urasabwa kubyara iyo myuka. Ariko, gahunda yumutekano wumuriro mubikoresho ukoresheje ibikoresho bya PTFE bigomba kuba birimo ibikoresho bya SCBA namahugurwa kubimenyetso byatinze.

Incamake - Menya Ingaruka, Teganya Ukurikije

Ibyingenzi byingenzi:

• Imyenda ya PTFE ifite umutekano mukoreshwa bisanzwe - ntabwo ibora munsi ya 300 ° C.

• Mu muriro, irekura hydrogène fluoride na perfluoroisobutylene (PFIB), byombi bifite uburozi bukabije.

• PFIB ni akaga cyane - nta mpumuro nziza, nta antidote, ibimenyetso byatinze.

• Ntuzigere ukoresha masike isanzwe. SCBA irakenewe.

• Nyuma yo guhura, shakisha ubuvuzi nubwo nta bimenyetso byihuse.

Aokai PTFE itanga impapuro zumutekano (SDS) kubicuruzwa byacu byose bya PTFE. Turasaba ko abakiriya basubiramo protocole yumuriro hamwe nitsinda ryabo ryumutekano.

Amakuru yavuzwe haruguru atangwa na Jiangsu Aokai Ibikoresho bishya Ikoranabuhanga Co, Ltd.

Niba wifuza kumenya byinshi kubisobanuro, gufata neza umutekano, hamwe nigisubizo cyabigenewe kuri PTFE yimyenda yubushyuhe bwo hejuru, kaseti, imikandara ya mesh, nibindi byinshi:

• Bwana Guo: +86 18944819998

• Bwana Liu: +86 13705266308

Twisunze filozofiya yubunyamwuga nubunyangamugayo, twiyemeje gutanga igisubizo kimwe na serivisi zitekereje.
