Izindaba - Iyini ukusetshenziswa kwepayipi le-PTFE

Isingeniso:

Ipayipi le-Polytetrafluoroethylene (PTFE) liwumkhiqizo oguquguqukayo kakhulu onganikeza izinhlelo zokusebenza eziningi ezimbonini eziningi ezahlukene. Likhiqizwa kusetshenziswa indlela yokukhipha i-paste. Ipayipi le-PTFE elenziwe nge-paste extrusion liyaguquguquka. Lingakhiqiza amapayipi e-PTFE anobubanzi obungaphakathi obungu-0.3 mm kuya ku-100 mm kanye nobukhulu bodonga obungu-0.1 mm kuya ku-2 mm.Ipayipi le-PTFEinokuqina okuhle kakhulu kwamakhemikhali, ingamelana nawo wonke ama-asidi aqinile, ama-alkali aqinile, ama-oxidant aqinile, futhi ayihlangani nezinyibilikisi ezahlukahlukene eziphilayo. Ingasetshenziswa ngokujwayelekile ngaphakathi kwe--60℃～+260℃, ngokumelana nokugqwala okuthembekile nokuhle kakhulu. Ingathutha igesi eqinile egqwalisayo kanye noketshezi ekushiseni okuphezulu. Ngaphezu kwalokho, ngemva kokuphathwa ekushiseni okuphezulu okungu-260℃ amahora ayi-1000, izakhiwo zayo zemishini azishintshi kakhulu. I-PTFE inezinto eziphansi kakhulu zokungqubuzana, iyinto enhle yokulwa nokungqubuzana, ezigcobayo, i-static friction coefficient yayo ingaphansi kwe-dynamic friction coefficient, ngakho-ke i-bearing eyenziwe ngayo inezinzuzo zokumelana kokuqala okuphansi kanye nokusebenza okuzinzile. Ngoba i-PTFE ayiyona i-polar, imelana nokushisa futhi ayimunci. Iphinde ibe nokumelana okuhle kokuguga, ukunganamatheli futhi ingashisi. Lokhu akukwazi ukushintshwa ngamanye amapayipi.

Isingeniso esilandelayo ukusetshenziswa kwepayipi le-PTFE ezimbonini ezahlukahlukene:

1. Imboni yamakhemikhali

Ngenxa yokuthi zinamandla aphezulu okumelana namakhemikhali cishe kuwo wonke amakhemikhali,Ipayipi le-PTFEkuyisinqumo esifanele embonini yamakhemikhali. Kubandakanya imboni ye-semiconductor. Inqubo yesimanje yokukhiqizwa kwe-semiconductor idinga ukulinganisa okuphephile kanye nokuthuthwa koketshezi olubolayo (ama-asidi nama-alkali). Lokhu kuzolimaza kakhulu ipayipi lokulethwa ngesikhathi esifushane.

2. Imboni yezokwelapha

Izakhiwo ezikhethekile zamapayipi e-PTFE zihlanganisa nesakhiwo sobuso esilula ukusihlanza. Eminyakeni eyishumi edlule, amapayipi e-PTFE abelokhu esetshenziswa kakhulu emishinini yezokwelapha. Ngenxa yokulingana okuphansi kokungqubuzana kwepayipi le-PTFE, lokhu kusho ukuthi ubuso balo bubushelelezi kakhulu futhi ngeke bumboze noma busize amagciwane akhule. Phakathi kwawo, amapayipi asetshenziselwa ukufaka amapayipi, ama-catheter, ama-pipettes nama-endoscopes. Iphinde ikhiqize amathuluzi ahlukahlukene nemishini, njengepayipi lokukhipha amanzi, ama-ventilator, ama-earring, irabha ye-apula, amagilavu kanye nezinye izicubu zokwenziwa. Ngaphezu kwalokho, amadivayisi amaningi asebenzayo asetshenziswa odokotela ekuhlaziyweni kwamakhemikhali abantu nawo enziwe ngezinto ze-PTFE.

3. Imboni yezindiza

Amapayipi e-PTFE angama-fluoropolymer angashi. I-coefficient yawo ephansi yokungqubuzana iwavumela ukuthi asebenze ngaphansi kwamazinga okushisa aphezulu kanye nokucindezeleka. Yingakho la mapayipi esetshenziswa imboni yezindiza ukugoqa izintambo kanye nezintambo.

4. Imboni yezimoto

Ezinjinini zezimoto, amapayipi kawoyela asezingeni eliphezulu enziwe nge-PTFE asetshenziselwa ukuhwamuka kukaphethiloli kanye nemizila kaphethiloli. Njengamanje, amapayipi amabhuleki emakethe wonke ayizinhlanganisela zamapayipi amabhuleki anamajoyinti. Ngokwezinhlobo ezahlukene zamabhuleki ezimoto, ihlukaniswe ngamapayipi amabhuleki e-hydraulic, amapayipi amabhuleki e-pneumatic kanye namapayipi amabhuleki e-vacuum. Ngokwezinto zayo, ihlukaniswe ngamapayipi amabhuleki e-PTFE, ipayipi lamabhuleki erabha kanye nepayipi lamabhuleki e-nylon. Ipayipi lamabhuleki erabha linezinzuzo zamandla aqinile okudonseka kanye nokufakwa okulula, kodwa ububi ukuthi ubuso buthambekele ekugugeni ngemva kokusetshenziswa isikhathi eside. Uma izinga lokushisa liphansi, amandla okudonseka epayipi lamabhuleki e-nylon ayabuthakathaka, uma ethintwa amandla angaphandle, kulula ukuwaphula. Kodwa-ke,Ishubhu le-PTFE lika-Bestefloninezici zokumelana nokushisa okuphezulu kanye nokushisa okuphansi, ukumelana nokucindezela okuphezulu, ukumelana nokuklwebheka, kanye nokumelana nokugqwala, okwenza ibe nokuphila isikhathi eside futhi ayidingi ukushintshwa njalo. Ingakwazi ukulungisa ukushiyeka kwezinye izinto ezimbili

5. Imboni kagesi

Amapayipi e-PTFE anezici zikagesi ezinhle kakhulu. Anezici eziphezulu ze-dielectric constant kanye ne-low loss factor ebangeni elibanzi kakhulu lemvamisa. Ngakho-ke, amapayipi e-PTFE asetshenziswa njengezinto zokuvikela ukushisa ezisezingeni eliphezulu, ezishisa kakhulu zezintambo nezintambo, kanye nezinto zokushisa zikagesi kanye nezinzwa zokushisa. Embonini kagesi, ukuze kuhlanganiswe izintambo nezintambo, kusetshenziswa amapayipi e-PTFE asezingeni eliphezulu, angamelana namazinga okushisa aphezulu futhi avikele izintambo kunoma yikuphi ukusika. Ngaphezu kwalokho, la mapayipi eza ngemibala ehlukahlukene ukusiza ukuhlonza izintambo ekhaya noma ehhovisi.

6. Imboni yokudla

Ngenxa yezici zayo ezilula ukuzihlanza nokunganamatheli, amapayipi e-PTFE polytetrafluoroethylene angasetshenziswa embonini yokudla. Ikakhulukazi, amapayipi enziwe nge-PTFE engagcwalisiwe afanelekile ngenxa yokungathathi hlangothi kwawo ngokomzimba futhi ahambisana neziqondiso ze-US Food and Drug Administration. Ngakho-ke, kuye kwafakazelwa ukuthi ayinangozi uma ithintana nepulasitiki nanoma yiluphi uhlobo lokudla. Ngakho-ke, amapayipi e-PTFE avame ukusetshenziswa emishinini yekhofi yendabuko. Ngaphezu kwalokho, kusetshenziswa amapayipi e-spaghetti abizwa ngokuthi amakamelo amabili noma amaningi kanye namapayipi anciphayo okushisa. Imikhiqizo ye-PTFE ingahlanzwa kusetshenziswa zonke izindlela ezivamile.

7. Imboni yezindwangu

Ukudluliselwa kwamakhemikhali emapayipini asetshenziswa embonini yezindwangu kungabangela ukugqwala. Ngakho-ke, ukuze kugwenywe le nkinga, kusetshenziswa ithubhu le-TPFE, bese kwenziwa isembozo se-PTFE kuroli yezindwangu.

Imboni Yokunyathelisa ye-8.3D

Ekuphrinteni kwe-3D, i-filament kufanele idluliselwe ku-nozzle yokuphrinta okumele yenziwe ebangeni lokushisa eliphezulu. Njengoba i-PTFE tube ine-coefficient yokushisa okuphezulu kanye nezakhiwo ezinganamatheli, kusiza ukuslayida kalula izinto kusuka ku-nozzle, ngakho-ke iyi-polymer efiseleka kakhulu embonini yokuphrinta ye-3D.

Imvelo ye-PTFE engeyona i-alkaline ivumela ukuthi isetshenziswe embonini yamakhemikhali, lapho ukudluliselwa koketshezi oluzwela kakhulu kuyinto evamile. I-Zhongxin Fluorine plastic Industry Co., Ltd. Igxile ekukhiqizweni kwamapayipi e-PTFE asezingeni eliphezulu iminyaka eyi-16.
