Isingeniso:
Ipayipi lePolytetrafluoroethylene (PTFE) liwumkhiqizo oguquguqukayo onganikeza inhlobonhlobo yezinhlelo zokusebenza ezimbonini eziningi ezahlukene.Ikhiqizwa kusetshenziswa indlela yokunamathisela ye-extrusion.Ipayipi le-PTFE elakhiwe ngokunamathisela i-extrusion liyavumelana nezimo.Ingakwazi ukukhiqiza amapayipi e-PTFE anobubanzi obungaphakathi obuncane obungu-0.3 mm kuya kubukhulu obungu-100 mm kanye nogqinsi oluncane njengo-0.1 mm kuya ku-2 mm.Ipayipi le-PTFEinokuqina okuhle kakhulu kwamakhemikhali, ingamelana nawo wonke ama-asidi aqinile, ama-alkali aqinile, ama-oxidants aqinile, futhi ayihlangani nezinyibilikisi ezihlukahlukene zezinto eziphilayo.Ingasetshenziswa ngokujwayelekile ngaphakathi -60℃～+260℃, enokwethenjelwa nokuhle kakhulu ukumelana nokugqwala.Ingakwazi ukuthutha igesi egqwalayo enamandla kanye noketshezi ezingeni lokushisa eliphezulu.Ngaphezu kwalokho, ngemva kokuphathwa ezingeni lokushisa eliphezulu 260℃ for 1000h, izakhiwo zayo mechanical has ushintsho oluncane.I-PTFE inesici esiphansi kakhulu sokungqubuzana, iyi-anti-friction enhle, impahla yokuzithambisa, i-coefficient yayo yokungqubuzana emile ingaphansi kwe-coefficient yokungqubuzana okuguquguqukayo, ngakho-ke ukuthwala okwenziwe kuyo kunezinzuzo zokumelana nokuqala okuphansi nokusebenza okuzinzile.Ngoba i-PTFE ayiyona i-polar, ayikwazi ukumelana nokushisa futhi ayimubi.Futhi inokumelana okuhle nokuguga, ukunganamatheli kanye nokungashi.Lokhu akukwazi ukushintshwa ngamanye amapayipi
Isingeniso esilandelayo ukusetshenziswa kwepayipi le-PTFE ezimbonini ezahlukahlukene:
1.Imboni yamakhemikhali
Ngoba anokumelana okuphezulu kwamakhemikhali cishe nawo wonke amakhemikhali,PTFE amashubhukuyisinqumo esihle embonini yamakhemikhali.Kubandakanya imboni ye-semiconductor.Inqubo yesimanje yokukhiqiza i-semiconductor idinga ukulinganisa okuphephile nokuthuthwa koketshezi olubolayo (ama-acids nama-alkali).Lezi zizolimaza kakhulu ipayipi lokulethwa ngesikhathi esifushane
2.Imboni yezokwelapha
Izakhiwo ezikhethekile zamapayipi e-PTFE futhi zihlanganisa ukwakheka okulula kokuhlanza kwendawo.Eminyakeni eyishumi edlule, amashubhu e-PTFE asetshenziswa kakhulu emishinini yezokwelapha.Ngenxa ye-coefficient ephansi yokungqubuzana kweshubhu le-PTFE, lokhu kusho ukuthi ingaphezulu layo libushelelezi kakhulu futhi ngeke livale noma lisize amagciwane akhule.Phakathi kwazo, amapayipi asetshenziselwa intubation, catheter, pipettes kanye endoscopes.Iphinde ikhiqize amathuluzi ahlukahlukene kanye nemishini, njengamapayipi okukhipha amanzi, ama-ventilator, amacici, irabha yama-apula, amagilavu nezinye izicubu zokwenziwa.Ngaphezu kwalokho, amadivaysi amaningi asebenzayo asetshenziswa odokotela ekuhlaziyeni amakhemikhali e-biochemical womuntu nawo enziwe ngezinto ze-PTFE
3.Imboni yezindiza
Amapayipi e-PTFE angama-fluoropolymer angashi.I-coefficient yabo ephansi yokungqubuzana ibavumela ukuthi basebenze ngaphansi kwamazinga okushisa aphezulu kanye nezingcindezi.Yingakho la mashubhu esetshenziswa yimboni yezindiza ukusonga izintambo nezintambo
4.Imboni yezimoto
Ezinjinini zezimoto, amapayipi kawoyela ekhwalithi ephezulu enziwe nge-PTFE asetshenziselwa ukuhwamuka kukaphethiloli kanye namarayili kaphethiloli.Njengamanje, Amapayipi amabhuleki emakethe wonke amapayipi amabhuleki anamajoyinti.Ngokwezinhlobo ezahlukene zamabhuleki ezimoto, ihlukene ngamapayipi ama-hydraulic brake, ama-pneumatic brake hoses nama-vacuum brake hoses.Ngokusho kwayo, ihlukaniswe ngepayipi le-PTFE brake, hose yerabha yebhuleki kanye nepayipi le-nylon brake.Ipayipi lebhuleki lerabha linezinzuzo zamandla aqinile aqinile nokufaka kalula, kodwa okubi ukuthi indawo engaphezulu ijwayele ukuguga ngemva kokusetshenziswa isikhathi eside.Endabeni yokushisa okuphansi, amandla aqinile we-nylon brake hose aba buthaka, uma ethintwa amandla angaphandle, kulula ukuphuka.Nokho,Ishubhu le-PTFE le-bestefloninezici zokushisa okuphezulu nokumelana nokushisa okuphansi, ukumelana nokucindezela okuphezulu, ukumelana nokuhuzuka, nokumelana nokugqwala, okwenza kube nempilo ende yesevisi futhi ayidingi ukushintshwa njalo.Angakwazi ukulungisa ukushiyeka kwezinye izinto ezimbili
5.Imboni kagesi
I-PTFE tubing inezici ezinhle kakhulu zikagesi.Zinezici zesici esiphezulu se-dielectric kanye nesici sokulahlekelwa okuphansi ebangeni elibanzi kakhulu.Ngakho-ke, amapayipi e-PTFE asetshenziswa njengezinga eliphezulu, izinga lokushisa eliphezulu lezinto zokuvikela izintambo nezintambo, kanye nezinto zokushisa zikagesi nezinzwa zokushisa.Embonini kagesi, ukuze kuhlanganiswe izintambo nezintambo, amapayipi aphezulu we-PTFE asetshenziswa, angakwazi ukumelana namazinga okushisa aphezulu futhi avikele izintambo kunoma yikuphi ukusika.Ngaphezu kwalokho, la mashubhu anemibala eyahlukene ukusiza ukukhomba izintambo ezisendlini noma ehhovisi
6.Imboni yokudla
Ngenxa yezici zayo ezilula ukuzihlanzeka nezinganamathele, amapayipi e-PTFE polytetrafluoroethylene angasetshenziswa embonini yokudla.Ikakhulukazi, amashubhu enziwe nge-PTFE engagcwalisiwe afanelekile ngenxa yokungathathi hlangothi kwawo ngokomzimba futhi athobela imihlahlandlela ye-US Food and Drug Administration.Ngakho-ke, kuye kwafakazelwa ukuthi akunangozi ekuthintaneni nepulasitiki nanoma yiluphi uhlobo lokudla.Ngakho-ke, amashubhu e-PTFE avame ukusetshenziswa emishinini yekhofi yendabuko.Ngaphezu kwalokho, okubizwa ngokuthi i-single-chamber noma amashubhu e-spaghetti aklanywe ngamakamelo amaningi kanye namashubhu angashiswa ukushisa asetshenziswa.Imikhiqizo ye-PTFE ingenziwa inzalo kusetshenziswa zonke izindlela ezijwayelekile
7.Imboni yezingubo
Ukudluliswa kwamakhemikhali emapayipini asetshenziswa embonini yendwangu kungabangela ukugqwala.Ngakho-ke, ukuze ugweme le nkinga, kusetshenziswa ithubhu ye-TPFE, futhi i-PTFE coating yenziwa ku-textile rolle.
8.3D Imboni Yokuphrinta
Ekuphrinteni kwe-3D, i-filament kufanele idluliselwe ku-nozzle yokuphrinta okufanele yenziwe ebangeni lokushisa eliphezulu.Njengoba amashubhu e-PTFE ane-coefficient ephezulu yokushisa kanye nezindawo ezingezona izinti, isiza ukushelela kalula into ephuma ku-nozzle, ngakho iyi-polymer efiseleka kakhulu embonini yokunyathelisa ye-3D.
Imvelo engeyona i-alkaline ye-PTFE ivumela ukuthi isetshenziswe embonini yamakhemikhali, lapho ukudluliswa koketshezi oluzwela kakhulu kuyisenzakalo esivamile.I-Zhongxin Fluorine plastic Industry Co., Ltd. Isebenza ngokukhethekile ekukhiqizeni amapayipi ekhwalithi ephezulu we-PTFE iminyaka engu-16
Ukusesha okuhlobene nepayipi le-ptfe:
