Intshayelelo:
Umbhobho wePolytetrafluoroethylene (PTFE) yimveliso eguquguqukayo kakhulu enokubonelela ngoluhlu olubanzi lwezicelo kumashishini amaninzi ahlukeneyo.Iveliswa kusetyenziswa indlela yokuncamathelisa extrusion.Umbhobho we-PTFE owenziwe ngokuncamathisela i-extrusion uyaguquguquka.Iyakwazi ukuvelisa imibhobho ye-PTFE kunye nobubanzi bangaphakathi obuncinci njenge-0.3 mm ukuya kubuninzi be-100 mm kunye nobukhulu bodonga obuncinane njenge-0.1 mm ukuya kwi-2 mm.Umbhobho we-PTFEinozinzo olugqwesileyo lweekhemikhali, inokumelana nazo zonke iiasidi ezomeleleyo, iialkali ezomeleleyo, ii-oxidants ezomeleleyo, kwaye ayidibanisi nezinyibilikisi ezahlukeneyo zezinto eziphilayo.Ingasetyenziswa ngokuqhelekileyo ngaphakathi -60℃～+260℃, enokwethenjelwa kunye nokumelana nokugqwesa okugqwesileyo.Inokuthutha irhasi eyomeleleyo eyingozi kunye nolwelo kwiqondo lobushushu eliphezulu.Ukongeza, emva kokunyangwa kubushushu obuphezulu be-260 ℃ ye-1000h, iipropathi zayo zomatshini zinotshintsho oluncinci.I-PTFE inomlinganiselo ophantsi kakhulu wokukhuhlana, yinto efanelekileyo yokuchasana ne-friction, i-self-lubricating material, i-coefficient yayo ye-static ingaphantsi kwe-coefficient ye-friction eguquguqukayo, ngoko ukuthwala okwenziwe kuyo kunenzuzo yokuxhathisa ukuqala okuphantsi kunye nokusebenza okuzinzileyo.Ngenxa yokuba i-PTFE ayiyo-polar, ayixhathisi ubushushu kwaye ayifunxanga.Ikwanayo nokumelana nokuguga okugqwesileyo, ukungancamatheli kunye nokungavuthi.Oku akunako ukutshintshwa ngamanye amabhobho
Le intshayelelo ilandelayo kusetyenziso lwepayipi le-PTFE kumashishini ahlukeneyo:
1.Ishishini lemichiza
Ngenxa yokuba banokumelana neekhemikhali eziphezulu phantse kuzo zonke iikhemikhali,Ityhubhu ye-PTFElukhetho olufanelekileyo kwishishini lemichiza.Kubandakanya ishishini le-semiconductor.Inkqubo yanamhlanje yokuveliswa kwe-semiconductor idinga ukulinganisa okukhuselekileyo kunye nokuthuthwa kolwelo olonakalisayo (i-acids kunye ne-alkali).Ezi ziza kulimaza kakhulu umbhobho wokuhambisa ngexesha elifutshane
2.Ishishini lezonyango
Iipropati ezikhethekileyo ze-PTFE imibhobho ikwabandakanya ulwakhiwo olulula ukucoca umphezulu.Kwiminyaka elishumi edlulileyo, iityhubhu ze-PTFE ziye zasetyenziswa kakhulu kwizixhobo zonyango.Ngenxa ye-coefficient ephantsi ye-friction ye-PTFE ityhubhu, oku kuthetha ukuba umphezulu wayo ugudileyo kwaye awuyi kugquma okanye uncede iibhaktheriya zikhule.Phakathi kwabo, i-hoses isetyenziselwa i-intubation, i-catheters, i-pipettes kunye ne-endoscopes.Ikwavelisa izixhobo ezahlukeneyo kunye nezixhobo, ezinjengemibhobho yokudonsa, ii-ventilators, amacici, irabha yeapile, iiglavu kunye nezinye izihlunu ezenziweyo.Ukongeza, izixhobo ezininzi ezisebenzayo ezisetyenziswa ngoogqirha kuhlalutyo lwe-biochemical yabantu zenziwe ngezinto ze-PTFE
3.Ishishini leenqwelomoya
Imibhobho ye-PTFE ziifluoropolymers ezingatshiyo.I-coefficient yabo ephantsi ye-friction ivumela ukuba basebenze phantsi kwamaqondo okushisa aphezulu kunye noxinzelelo.Yiloo nto le mibhobho isetyenziswa lishishini leenqwelomoya ukusonga iingcingo neentambo
4.Ushishino lweemoto
Kwiinjini zemoto, imibhobho yeoli ekumgangatho ophezulu eyenziwe nge-PTFE isetyenziselwa ukuphuphuma kwamafutha kunye neentsimbi zamafutha.Okwangoku, i-hoses ye-brake kwimarike zonke ziiassemblies ze-brake hose kunye namalungu.Ngokweentlobo ezahlukeneyo zeziqhoboshi zemoto, yahlulwe yaba yimibhobho ye-hydraulic brake hoses, i-pneumatic brake hoses kunye ne-vacuum brake hoses.Ngokwezinto zayo, yahlulwe kwi-PTFE i-hose ye-brake, i-rubber brake hose kunye ne-nylon brake hose.I-hose ye-rubber brake ineengenelo zamandla okuqina aqinile kunye nofakelo olulula, kodwa into engalunganga kukuba umphezulu ulungele ukuguga emva kokusetyenziswa kwexesha elide.Kwimeko yokushisa okuphantsi, amandla okuqina e-nylon brake hose ayancipha, ukuba achaphazeleka ngamandla angaphandle, kulula ukuphuka.Nangona kunjalo,ityhubhu ye-PTFE ye-Besteflonineempawu zokushisa okuphezulu kunye nokumelana nokushisa okuphantsi, ukunyanzeliswa koxinzelelo oluphezulu, ukunyanzeliswa kwe-abrasion, kunye nokumelana nokubola, okwenza kube nobomi obude benkonzo kwaye ayifuni ukutshintshwa rhoqo.Unako ukwenza ukusilela kwezinye izinto ezimbini
5.Ishishini lombane
Ityhubhu ye-PTFE ineempawu ezibalaseleyo zombane.Baneempawu eziphezulu ze-dielectric kunye ne-low loss factor kuluhlu olubanzi kakhulu.Ke ngoko, imibhobho ye-PTFE isetyenziswa njengomgangatho ophezulu, ubushushu obuphezulu bezinto zokukhusela iingcingo kunye neentambo, kunye nezinto zokufudumeza zombane kunye nezinzwa zobushushu.Kwishishini lombane, ukwenzela ukugubungela iingcingo kunye neentambo, iipayipi ze-PTFE eziphezulu zisetyenzisiweyo, ezinokumelana nokushisa okuphezulu kunye nokukhusela iingcingo kuyo nayiphi na ukusika.Ukongeza, le mibhobho iza ngemibala eyahlukeneyo ukunceda ukuchonga iingcingo zekhaya okanye iofisi
6.Ishishini lokutya
Ngenxa yeempawu zayo ezilula ukucoceka kunye nezinganamatheli, imibhobho ye-PTFE polytetrafluoroethylene ingasetyenziswa kushishino lokutya.Ngokukodwa, iibhubhu ezenziwe nge-PTFE ezingazaliswanga zifanelekile ngenxa yokungathathi hlangothi kwazo kwaye zithobela izikhokelo ze-US Food and Drug Administration.Ngoko ke, kuye kwafakazelwa ukuba ayinabungozi ekudibaneni neplastiki kunye naluphi na uhlobo lokutya.Ke ngoko, iityhubhu zePTFE zihlala zisetyenziswa koomatshini bekofu bemveli.Ukongezelela, okubizwa ngokuba yi-single-chamber okanye i-multi-chamber design ye-spaghetti iityhubhu kunye neetyhubhu ezitshisa ukushisa zisetyenziswa.Iimveliso ze-PTFE zinokuvalwa kusetyenziswa zonke iindlela eziqhelekileyo
7.Ishishini leempahla
Ukutshintshwa kweekhemikhali kwimibhobho esetyenziswa kwishishini lempahla yengubo kunokubangela ukubola.Ngoko ke, ukuze ugweme le ngxaki, ityhubhu ye-TPFE isetyenzisiweyo, kwaye i-PTFE yokugqoka iqhutyelwa kwi-textile rolle.
8.3D Umzi mveliso woShicilelo
Kwiprinta ye-3D, i-filament kufuneka idluliselwe kwi-nozzle yokushicilela ekufuneka yenziwe kwiqondo lokushisa eliphezulu.Ekubeni i-PTFE ityhubhu inomlinganiselo wobushushu obuphezulu kunye neempawu ezingabambekiyo, inceda ukutyibilika ngokulula imathiriyeli ukusuka kumbhobho, ngoko ke yeyona polima inqwenelekayo kushishino loshicilelo lwe-3D.
Ubume obungeyiyo i-alkaline ye-PTFE ivumela ukuba isetyenziswe kwishishini lemichiza, apho ukuhanjiswa kolwelo olubuthathaka kakhulu luyinto eqhelekileyo.I-Zhongxin Fluorine I-Plasitiki Industry Co., Ltd. Isebenza ngokukhethekileyo ekuveliseni imibhobho ye-PTFE ekumgangatho ophezulu iminyaka eli-16.
