Zintu zya PFA

Misyobo yazintu

bupanduluzi

PFA, iizyibidwe kuti PTFE iikonzya kunywika, ilijisi bube bukozyenye a PTFE, mpawo bube bwayo bwakugwisya magesi bulisumpukide ziindi zili 3-4 kwiinda PTFE. Aboobo, yakabelesegwa kapati mu Reactor Lining, Semiconductor, Medical, Automotive azimwi zibeela. Zintu zipati zibikkilizya musako wakuwelda wa PFA, musako wa PFA alimwi atuyubu. Mapaipi aa PFA aasalala kapati aapangwa ku Micflon akabelesyegwa kapati mumbazu zya Semiconductor a Medical.

Zitondeezyo

Zintu zya PFA (Perfluoroalkoxy) zipangwa kuzwa kumusyobo wa fluoropolymer uukozyenye a PTFE (Polytetrafluoroethylene) pesi ulaampindu ziindene, ikapati mukukonzya kusungwaazyigwa. Yakabambilwa kuti ibe nzila imwi yakupya kapati kwiinda FEP (Fluorinated Ethylene Propylene), PFA ilazumanana kuba anguzu zyakukazya misamu, kutamvwanana kusyoonto, alimwi akubula nguzu zyakukakatila zili mbuli ma fluoropolymers kumwi kazumizya kubamba kwiinda mukubelesya nzila zya thermoplastic mbuli kubumba, kugwisya, akuwelda. Ooku kusungwaazya kusungwaazya kuyungizya bube bukatazya kumvwisisisya anzila zyakupanga zikonzya kuchitwa kweelanisigwa a PTFE, eeyo iiyandika kubelesegwa minchina naakuti kubumbwa kwiinda mukubelesya minchina.

Zintu zipati zya PFA

• Kukazya Makemikalu Kwaalubazu: Mbubwenya mbuli PTFE, PFA taikwe nguzu zyamakemikalu manji, kubikkilizya ama asidi mayumu, ma base, alimwi azintu zipa kuti zintu zibe kabotu, calo cipa kuti kaili kabotu mumasena aakonzya kubola kapati.

• Kupya Kupati: PFA ilakonzya kubeleka kabotu kuzwa ku -200°C kusikila ku +260°C (-328°F kusikila ku +500°F), kweelanisigwa a PTFE mpawo yiinda FEP.

• Mweelwe Musyoonto Wakuzwangana: PFA itondezya mweelwe musyoonto loko wakuzwangana, kupa kuti kutabi kujatana akulikwabilila.

• Busalali bupati: Zimwi zibeela zya PFA zilajanwa antoomwe azintu zikonzya kugwisigwa zili munsi-munsi, zipa kuti kazili kabotu kubelesyegwa muzibelesyo zya semiconductor, misamu, alimwi azyabusilisi.

• Kukwabilila magesi kubotu: PFA ilijisi nguzu zyamagesi zipati alimwi akubula nguzu zyakugusya magesi, calo cipa kuti ibe nzila mbotu yakukwabilila magesi. Nguzu zyakwe zya dielectric zilisumpukide kwiinda PTFE.

• Kukonzya kusungwaazya: Oobu mbobubotu bupati kwiinda PTFE, ikuzumizya kubamba zibeela zikatazya kumvwisisisya kwiinda mukubumba akuzigwisya. Alimwi chilagwasya kuwelda zibeela zya PFA.

• Buumi Bwakukotama Bupati: PFA kanjikanji ilaa buumi bwakukotama buli kabotu (kukazya kukotama akukotama ziindi zyiingi) kweelanisigwa a FEP. Nikuba kuti chili munsi abuumi bwa PTFE, chilizulide kumilimo myiingi.

• Kukazyigwa Kubotu Kwakunjilila: PFA ilakwabilila kubotu kuzwa kukunjila kwamuwo amaanzi.

• Kusalala kwameso: PFA ilasalala kwiinda PTFE, eeyo iikonzya kugwasya mumilimo iiyandika kulanga-langa maanzi.

• Kweendelana azintu zipona: PFA ilakonzya kuchitwa mumakilasi aakonzya kuzuzikizya ziyandikana zya USP Class VI, akupa kuti ibeleke kabotu kubelesyegwa mubusilisi.

• Kukakatila kuchiindi: PFA itondezya kukazyigwa kubotu ku UV, ozone, akuzungaana koonse.

Zintu zya PFA zidumide akubelesya

Akaambo kakusanganya zintu zilibedelede, PFA ilabelesyegwa muzintu zyiingi zyaandeene mumakkampani miingi:

• Tubing and Hoses: Kubelesya maanzi aamuwo mukutola misamu, zibelesyo zyabusilisi, ma laboratory, akupanga ma semiconductor akaambo kakubula nguzu kwamakemikalu, kukazyigwa akupya, akusalala kupati. I PFA tubing iijisilidi ilakonzya kupa kuti kube kuchincha.

• Zyakuvwumba: Mbuli zyakuvwumba zitanamati alimwi zitanjililwi amakemikalu kuzibelesyo zyakujika, zibelesyo zyakupanga makemikalu (mapompi, matanki, mavalvu, zilongo), azimwi zibelesyegwa ziyandika kukwabililwa kuzwa kukubola.

• Zibeela zya Semiconductor: Zibikkilizya zibelesyo zyakunyamuna ma wafer, nzila zyakutola makemikalu, tubing, azibelesyo oomo kusalala kupati akukazya makemikalu mapati nchintu chipati. PFA ili munsi-munsi aabutale busyoonto kweelanisigwa a PTFE kanjikanji njiiyandisi.

• Zibelesyo zyakubelesya mu laboratory: zilimbuli nkomeki, mabbodela, mabbodela, azibelesyo zyakuzungaanya akaambo kakuti tazibelesyi misamu alimwi nzyuba kuzisalazya.

• Zibelesyo zyabusilisi azibelesyo zyakupanga misamu: Kubikkilizya azibelesyo zyakuswaanganya, zijatikizyidwe, ma syringe, azibelesyo zyakuvwumbilila ooko kuyandika kweendelana abuumi akukazya nzila zyakugwisya tuzunda (autoclave, EtO, e-beam, gamma).

• Kukwabilila ntambo antambo: Kumilimo iiyandika kukwabilila kupya kapati, kukwabilila magesi kubotu, akukwabilila misamu, mbuli mumakkompiyuta amumagesi.

• Zivwunisyo: Kumapaipi, matanki, azibelesyo zimwi mukupanga misamu kuti zitanyonyooki, kanjikanji zipa kuti kube kubelesya zintu zitayandiki mali manji mbuli nsimbi zya carbon.

• Zijazyo a O-rings: Mumilimo iiyandika kukazyigwa amakemikalu akupya kwachiindi chilamfu. Nikuba kuti PTFE kanjikanji ilaa buumi buli kabotu, PFA ilakonzya kuba nzila imwi yeelede nkaambo kakukonzya kubelesegwa mukupanga zintu zikatazya kumvwisisisya.

• Zibeela Zyakabambilwa aKuchitwa: Kubelesya PFA's melt processability muzibeela zikatazya kumvwisisisya mumilimo yiindene-indene, kupa nzila yakupanga iisalala kweelanisigwa akupanga PTFE. Zikozyanyo zibikkilizya maanda aapompi, zibeela zyavalvu, antoomwe azintu zikwabilila.

• Heat Shrink Tubing: Yakukwabilila akukwabilila zibeela zikonzya kupya.

• Mafilimu aamapepa: Abelesyegwa mumilimo isiyene-siyene iiyandika kukazyigwa amakemikalu, kukwabilila magesi, naakuti zintu zitanamati.

Kusiyana Kupati Akati ka PFA a PTFE

Nikuba kuti zyoonse zyobile nzintu zibeleka obotu zya fluoropolymers zili azintu zyiingi zyeelene, kwiimpana kupati kuli muli:

• Kukonzya kusungwaazyigwa: PFA ilakonzya kusungwaazyigwa kubelesya nzila zya thermoplastic, kutali mbuli PTFE.

• Buumi bwakusanduka: PTFE kanjikanji ilaa buumi bwakusanduka bupati kwiinda PFA.

• Kusalala: PFA ilakonzya kuchitwa kakwiina nsimbi zisyoonto, aboobo ilakonzya kubelesegwa muzibelesyo zya semiconductor azyakusalala kupati.

• Kusalala: PFA ilasalala kwiinda PTFE.

• Muulo: PFA kanjikanji iladula kwiinda PTFE.

• Kukazya kuzungaana: PFA itondezya kukaka kuzungaana kubotu loko aawo nokwapya kapati kweelanisigwa a PTFE.

• Kukonzya kuweldwa: PFA ilakonzya kuweldwa, kupa bubotu mukupanga zintu zikatazya kumvwisisisya.

Mukumanizya, zintu zya PFA zipa kusanganya kubotu kwamakemikalu, kupya, amagesi antoomwe abubotu bwakusanzya, zipa kuti zibe nzila mbotu yakubelesya mumakkampani miingi. Ziyandikana zyakubelesya, kubikkilizya akujatikizigwa kwamakemikalu, kupya, kukatazyigwa kwaminchina, ziyandikana zyakusalala, antoomwe abwaanda bwazibeela, ziyoopa kuti naa PFA ninzila mbotu yakubelesya fluoropolymer kweelanisigwa a PTFE naakuti zimwi zintu.
