Uloliwe wokuqala waseTshayina onqumla ulwandle ohamba ngesantya esiphezulu phakathi kweFuzhou neXiamen uyeza, apho ibhulorho ehlala ngentambo iye yakhiwe ngempumelelo ngoncedo lwePTFE polytetrafluoroethylene, ukumkani weeplastiki.Masithethe malunga nosetyenziso lwe-PTFE owaziwa kancinci kuwe.
Ibhulorho yaseTaicheng Xite yenye yeebhulorho phakathi kweFujian kunye neXiamen High-speed Railway.Ibhulorho iyilwe njengebhulorho engalungelelananga ejikelezayo enentambo enobunzima obuziitoni ezingama-38,000.Ubude obupheleleyo benxalenye ejikelezayo yi-221.3 yeemitha, eyona bhulorho enkulu engalungelelananga ejikelezayo ehlala intambo kaloliwe ohamba ngesantya esiphezulu eTshayina ngokwe tonnage.
Ingaba into enkulu kangaka enetoni enje ilugqibezela njani “uguquko oluhle”?Oku akunakwenziwa ngaphandle kwe-fluoropolymer ephezulu yokusebenza: isilayidi se-teflonrs.Ingaba iTeflon encinci isilayidi ingayenza njani ibhulorho yeetoni ezili-10,000 ukujika ngokukhululekileyo?
Umgaqo osisiseko womzimba ojikelezayo kukuseta i-hinge yebhola ye-sliding layer phakathi kwesakhiwo esiphezulu nesisezantsi somzimba ojikelezayo ochasene noxinzelelo oluphezulu kunye ne-coefficient encinci ye-friction.Ihenjisi yebhola yenziwe ngehenjisi yebhola ephezulu, ilungisiweisilayidi seteflonrkunye nehenjisi yebhola esezantsi,neihenjisi yebhola ephezulu nasezantsisibekwe kwi-turntable ephezulu nasezantsi.
Ngamagama alula, umgaqo ufana nediski yokugaya ilitye, apho isiseko singahambi kwaye inxalenye ephezulu ijikeleza kwiziko lokugaya.Ngoko ke amandla okukhuhlana phakathi kweehenjisi zebhola kufuneka woyiswe ngexesha lokujikeleza.Indlela yokunciphisa ukuchasana kwe-friction yingxaki engundoqo yobugcisa ekwakhiweni komzimba ojikelezayo.
PTFEisilayidiidlala indima ebaluleke kangaka ngenxa yayoukuzithambisa okugqwesileyo,esezantsiI-coefficient ye-friction eguqukayo kunye ne-static, kunye nokunxibakunye noxinzeleloukuxhathisa.Emva kokugqiba ukufakwa kwe-PTFEisilayidi,ihenjisi yebhola engaphezulu nesezantsiskwaye i-shaft esembindini iqatyweti-eflon powder grease lubrication medium,enokuthiukunciphisa ifukukrazula.Ukongezelela, i-shaft ejikelezayo inePTFEityhubhu, enokunciphisa ukungqubana okwenziwa kwinkqubo yokuguqula umzimba.NjengeencinciPTFEisilayidikufanelehayive amandla amangalisayo!
Iimpawu ze-PTFE
● Ukumelana nokushisa okuphezulu
Ubushushu bayo bokusebenza bunokufikelela kuma-250 ℃.
● Ukumelana nobushushu obuphantsi
Inobunzima obuhle bomatshini kwiqondo lokushisa eliphantsi;nokuba iqondo lobushushu lehla ukuya ku -196 ℃, linokugcina ubude be 5%.
● Ukumelana nokubola
Ingangeni kwiikhemikhali ezininzi kunye nezinyibilikisi, kwaye inokumelana neeasidi ezomeleleyo kunye neealkali, amanzi kunye nezinyibilikisi ezahlukeneyo zendalo.
● Ukumelana nemozulu kakuhle
Inobomi bokuguga obungcono kakhulu phakathi kweeplastiki.
● Ukuthambisa okuphezulu
I-PTFE inowona mlinganiso usezantsi wokukhuhlana phakathi kwemathiriyeli eqinileyo.
● Ukungancamathiseli
Inobunzima bomgangatho osezantsi phakathi kwezinto eziqinileyo, kwaye ayibambeleli kuyo nayiphi na into.
Izicelo zenkosi yeeplastiki
I-PTFE inokwenziwa ngamashiti, iityhubhu, iintonga, iifilim, iintsinga kunye neengubo ngokokuhlelwa kwemveliso, kwaye isetyenziswa ngokubanzi kwiinkalo ezahlukeneyo ezifana neekhemikhali, i-petroleum, impahla, umbane kunye ne-elektroniki, unyango, oomatshini kunye ne-aerospace.
● Ezonyango
I-PTFE ayinamanzi, i-inert ye-physiologically, kunye ne-non-adhesive, ngoko isetyenziswa kwizinto ezininzi zokulungisa izihlunu kunye nezixhobo ezenziweyo zamalungu, njengemithambo yegazi eyenziweyo, kunye ne-membrane yokulungisa intliziyo, njl njl. ungathobeki xa utshiswe phantsi koxinzelelo oluphezulu okanye unyangwe ngeentsholongwane ezahlukeneyo.Ke ngoko, isetyenziswa kakhulu kwizixhobo zonyango ezinje ngeesutures, iipads ezinyumba, kunye neenaliti zokutofa.
● I-elektroniki kunye neyombane
I-PTFE ineempawu ezibalaseleyo zedielectric kunye nozinzo oluphezulu kakhulu lwe-thermal, kwaye iyimathiriyeli yokugquma umbane engenakubuyiselwa, idlala indima ebalulekileyo kwinkalo yokufakelwa kombane kunye ne-elektroniki.Umzekelo, ilaphu le-lacquer yeglasi ye-PTFE isetyenziselwa ukuvelisa ubushushu obuphezulu kunye nezixhobo zokugquma rhoqo, ezinokuthi zisetyenziswe kunxibelelwano lwesathelayithi kunye neekhompyuter;Ifilimu ye-PTFEisetyenziselwa ukwenza ii-capacitors njenge-insulation layer, i-padding kunye neentambo phakathi kwezixhobo;Iityhubhu ze-PTFE ezibhityileyo ezinodonga olwahlukeneyo zingasetyenziselwa imikhono yocingo olulothe, iityhubhu ezicuthekayo zobushushu kunye neetyhubhu ezijikelezayo, kunye nemibhobho yelothe egqunyiweyo yeejenereyitha, njl.
Kwintsimi yonxibelelwano lwe-5G, i-PTFE iphinda isetyenziswe ngokubanzi kwiifilitha zesikhululo sesiseko, i-high-frequency high-speed PCB / FPC, inkqubo ye-chip ye-5G kunye nezixhumi eziphezulu ze-frequency kunye neentambo.Okwangoku, izihluzi ze-5G ezisetyenziswa ngabathengisi abakhulu bezixhobo zonxibelelwano zisasenziwa ngeefilitha zentsimbi zentsimbi, ezisebenzisa amacandelo amaninzi e-PTFE ukuxhasa kunye nokugquma.
● Oomatshini
Kulo naluphi na uhlobo lomatshini kunye nezixhobo, i-lubrication kufuneka iqhutyelwe kwi-sliding surface ngexesha lomsebenzi ukunciphisa i-friction factor, ukunciphisa ukunxiba kunye nokushisa kwamalungu, ukuqinisekisa umthamo oqhelekileyo wokusebenza, ukuchaneka kunye nokusetyenziswa kwamandla omatshini kunye nezixhobo.I-PTFE's low coefficient of friction and self-lubricating properties ivumela ukuba isetyenziswe ekwenziweni kweebheringi, amakhonkco episton, izikhokelo zesixhobo somatshini kunye nemathiriyeli yokutywina, kodwa idla ngokusetyenziswa kwizixhobo ezichanekileyo okanye iasidi kunye nealkali ukumelana nokusingqongileyo kuba kuyabiza.
● Impahla
I-PTFE eyandisiweyo(i-e-PTFE) ifilimu ilayitiwe ngamalaphu aqhelekileyo ukwenza amalaphu alaminated angangeni manzi kunye nokufuma.Iimpawu zayo ezibalaseleyo zamandla aphezulu, ukushwabana okuphantsi, ukunganamatheli kunye nokuguga okuchasene ne-UV kwenza i-e-PTFE ifayibha ibe lilaphu lokuzikhethela kwimpahla yezemidlalo yangaphandle.Ukongeza, isoloko isenziwa kwiisuti zokucima umlilo, iisuti ze-astronaut, iisuti zokukhusela zonyango, iisuti zokulwa emkhosini, iingxowa zokulala kunye neentente ezilula.
● Iimoto & nezothutho
Kwisixhobo sokutywinwa kweoyile yemoto, inokwahlula iindawo ezifuna ukuthambisa kwiindawo zokuhambisa kwiindawo eziphumayo ukuthintela ukuvuza kweoyile yokuthambisa.Ifilimu ephefumulayo ye-PTFE isetyenziselwa izibane zemoto ukulinganisa uxinzelelo ngaphakathi nangaphandle kwezibane kunye nokuthintela ungcoliseko oluziswe ngamanzi, uthuli, kunye nolwelo lweemoto, njl.
● Imichiza
I-PTFE, ngenxa yokunganyangeki kwayo, isetyenziswa njengesixhobo sokunqanda ukubola ukwenza iindawo ezahlukeneyo zokulwa nokubola, njengemibhobho, iivalvu, iimpompo kunye nokufakwa kwemibhobho.Kwizixhobo zekhemikhali, inokwenza i-lining kunye ne-coating ye-reactors, ii-distillation towers kunye nezixhobo zokulwa nokubola.
Fumana eyona PTFE umenzi
Ukwenza usebenziso oluninzi lweemveliso zePTFE, ungakhetha ngcono oyena mvelisi wePTFE, kunye neSuKo, yase China eyaziwa kakhuluPTFE umenzi ityhubhu, lolona khetho lulungileyo.Ingcaphephe kwi-PTFE/UHMWPE extrusion kunye neemveliso kwiindidi ezahlukeneyo kunye neemodeli, uSuko uhlala ephambili kushishino lweTetrafluorohydrazine ngobuchule obutsha, ubuchwephesha kunye nobukrelekrele ngaphakathi nangaphandle.
