Polytetrafluoroethene,isifinyezo:PTFE
Isibizo: PTFE, tetrafluoroethylene, ukumkani weplastiki, F4.
Izinto ezilungileyo zePTFE
PTFEziiplastiki ezikhethekileyo zobunjineli, okwangoku zizixhobo ezimelana nomhlwa, ezaziwa ngokuba "yinkosi yeplastiki".Iimpawu eziphambili ziphezulu kwaye ziphantsi ukumelana nobushushu, ukumelana nokugqwala, ukugquma okuphezulu, ukumelana nokuguga, ukuzithambisa.
Isetyenziswa kwi-aerospace, i-electronics kunye nezixhobo zombane, ishishini lemichiza, oomatshini kunye nezixhobo, ukutya kunye nonyango, iimpompo, iivalvu kunye nemibhobho, iimoto kunye neenqanawa, iicompressor zomoya, njl. ishishini.
PTFE molekyuli inert F athom ekhusela nokukhusela CC bond, kwaye CF bonding amandla uzinzile ingakumbi, ikhonkco molekyuli kunzima ukuba itshatyalaliswe, sisakhiwo ezinzile kakhulu.Olu lwakhiwo lwemolekyuli lukwachaza ezi mpawu zilandelayo zibalaseleyo ze-PTFE.
Ukuchasa umhlwa:Ukongeza kwisinyithi esinyibilikisiweyo sealkali kunye nezinyibilikisi ezimbalwa ezifana nee-alkane hydrocarbons ezingaphezulu kwama-300 degrees Celsius, iyamelana nokubola kwexesha elide ngayo nayiphi na eminye imichiza.
Ukumelana namaqondo aphezulu kunye namaqondo aphantsi: ingasetyenziselwa ixesha elide kwi -60 + 260 ℃.
Ukuthambisa okuphezulu:oyena mlinganiso umncinci wokukhuhlana phakathi kwemathiriyeli eqinileyo, nomkhenkce awunakuthelekiswa nawo.
Ukungancamathiseli:olona xinzelelo luncinci lomphezulu phakathi kwezinto eziqinileyo, alubambeleli kuyo nayiphi na into.
Ukuxhathisa iMozulu:Ubomi obude obude phakathi kweeplastiki.
Ukungeyotyhefu:Isixhobo singasetyenziswa njengemithambo yegazi eyenziweyo, engeyiyo netyhefu kunye ne-non-aleji kunye nezinye iziphumo ezibi, ukutya kunye nezixhobo zebakala lamayeza.
Iimpawu zokugquma:ifilim engqindilili njengephephandaba yanele ukuxhathisa amandla ombane aphezulu angama-1500V.
Ukongeza, i-PTFE ayinakho ukufunxa ukufuma, ukungatsha, kwaye igqithise kakhulu kwi-oxygen, ukukhanya kwe-ultraviolet.
Izinto ezingeloncedo kwi-PTFE
Nangona i-PTFE inomsebenzi oncomekayo obanzi, kodwa amandla omatshini aphantsi, i-coefficient enkulu yokwandiswa komgca, ukuxhathisa okungahambi kakuhle, ukuxhathisa okungahambi kakuhle, ukungahambi kakuhle kwe-thermal kunye nezinye iintsilelo.Kumandla omatshini kunye nezinye iimeko ezintsonkothileyo, ezinjengokusetyenziswa kushishino lokutywinwa kwevalve kunye nomda wayo wokwenene wosetyenziso olukhuselekileyo lobushushu buhlala ngaphakathi -70 ~ +150℃.Ukuze unqobe ezi ntsilelo, i-PTFE resin inokuzaliswa ngama-agent okuqinisa ukuphucula iimpawu zomatshini wezinto eziphathekayo, ukwenzela ukwandisa ububanzi bokusetyenziswa kwezinto zayo.
Intshayelelo kwiipropati ze-PTFE ezinemibala
Umbala wentsusa we PTFE lubisi olumhlophe, ngelixa i-PTFE enemibala kungenxa yokuba imathiriyeli yesiseko ye-PTFE izaliswe ngezinto ezincedisayo.Izinto ezincedisayo zinokwahlulwa zibe ngamacandelo amabini ngokokusetyenziswa: i-ejenti yokuphucula kunye ne-ejenti yomgubo wombala.
Iklasi ye-agent ye-powder yombala: izaliswe ngumgubo wombala kwi-PTFE, ingaba ngokukhululekileyo emnyama, etyheli, ebomvu, eluhlaza, eluhlaza okwesibhakabhaka njalo njalo.I-agent ye-powder yombala kuphela ukutshintsha umbala we-PTFE, umlinganiselo we-filler yimali encinci ngoko umphumo we-PTFE wentsebenzo yasekuqaleni unokungahoywa.Ngokwethiyori, i-agent ye-powder yombala kufuneka ikwazi ukuchaphazela ukuzinza kweekhemikhali ze-PTFE, i-insulation, amandla okuqina kunye nezinye iimpawu zomatshini.Ke ngoko, ezinye izihlandlo ezikhethekileyo kufuneka wazi ngazo.I-PTFE enemibala ihlangabezana neemfuno zabathengi abaneemfuno zemibala ebonakalayo.
Ukuthenga i-PTFE ityhubhu elungileyo ayikokukhetha kuphela iinkcukacha ezahlukeneyo kwizicelo ezahlukeneyo.Okunye ukukhetha umenzi othembekileyo.BesteflonI-Fluorine plastic Industry Co., Ltd. igxile kwimveliso yomgangatho ophezuluImibhobho ye-PTFEkunye nemibhobho iminyaka engama-20.Ukuba nayiphi na imibuzo ityhubhu ptfe kunye neemfuno, nceda uzive ukhululekile ukudibana nathi ukuze ufumane iingcebiso zobungcali.
