Yintoni iPEEK?
Polyether ether ketone(PEEK) sisixhobo sepolymer esinevumba elimnandi. Luhlobo lweplastiki yobunjineli ekhethekileyo esebenza ngokugqwesileyo, ngakumbi ebonisa ukumelana nobushushu obuqinileyo, ukuxhathisa ukukhuhlana kunye nokuzinza komda. Isetyenziswa kakhulu kwi-aerospace, emkhosini, kwimoto, amayeza kunye namanye amacandelo.
Ukusebenza okusisiseko kwe-PEEK
I-PEEK inamandla omatshini aphezulu, ukumelana nobushushu obuphezulu, ukuxhathisa impembelelo, ukunqanda ilangatye, ukuxhathisa kwe-asidi kunye ne-alkali, ukuxhathisa i-hydrolysis, ukuxhathisa i-abrasion, ukumelana nokukhathala, ukuxhathisa kwi-radiation kunye neempawu ezilungileyo zombane.
Lelona bakala liphezulu lokumelana nobushushu kwiiplastiki ezikhethekileyo zobunjineli.
Ubushushu benkonzo yexesha elide bunokusuka ku -100 ℃ ukuya kuma 260 ℃.
Izixhobo zeplastiki zePEEK zineempawu eziphakamileyo zozinzo. Ubume obunobushushu obukhulu kunye nokutshintsha komswakama kunempembelelo encinci kubungakanani beendawo ze-PEEK, kwaye isantya se-PEEK sokubumba isitofu sincinci, esenza ukuba ukuchaneka komlinganiselo weendawo ze-PEEK zibe phezulu kakhulu kuneeplastiki eziqhelekileyo, ezinokuhlangabezana neemfuno ukuchaneka okuphezulu phantsi kweemeko zokusebenza.
I-PEEK inobushushu obubonakalayo-impawu ze-hydrolysis ezixhathisayo.
Kwimekobume yobushushu obuphezulu kunye nokufuma okuphezulu ukufunxa kwamanzi kuphantsi kakhulu, kufana nenylon kunye nezinye iiplastiki ngenxa yokufunxa kwamanzi kunye nobukhulu beenguqu ezicacileyo.
I-PEEK inokuqina okugqwesileyo kunye nokumelana nokudinwa, okuthelekiswa ne-alloys, kwaye ingasetyenziselwa ixesha elide kwiindawo zokusebenza ezifunayo. Ukutshintsha intsimbi, i-aluminium, ithusi, i-titanium, i-ptFE kunye nezinye izinto eziphezulu zokusebenza, ukuphucula ukusebenza komatshini ngexesha elifanayo ukunciphisa kakhulu iindleko.
I-PEEK inokhuseleko oluhle. Iziphumo zovavanyo lwe-UL yezinto eziphathekayo zibonisa ukuba isalathisi se-PEEK se-flame retardation yiBanga le-V-0, elilona bakala liphezulu lokubuyiswa komlilo. Ukutsha kwe-PEEK (oko kukuthi, ubungakanani bomsi ovelisiweyo ngexesha lokuvutha okuqhubekayo) ngowona uphantsi kuyo nayiphi na iplastiki.
Ukungakwazi kwegesi ye-PEEK (uxinzelelo lwerhasi eveliswayo xa ibolile kubushushu obuphezulu) nayo iphantsi.
Imbali yePEK
I-PEEK yeyona nto iphezulu kwiphiramidi yeplastiki, kwaye zimbalwa iinkampani emhlabeni eziye zayibamba kakuhle inkqubo yepolymerization.
I-PEEK yaphuhliswa yi-ICI ngeminyaka yee-1970. Ngenxa yeepropathi zayo ezibalaseleyo zoomatshini kunye neepropathi zokusetyenzwa, yaba yenye yezona plastiki zibalaseleyo zobunjineli ezikhethekileyo.
Itekhnoloji yePEEK yaseTshayina yaqala ngeminyaka yoo-1980. Emva kweminyaka yophando olunzima, iYunivesithi yaseJilin yavelisa inkqubo ye-PEEK resin synthesis kunye namalungelo azimeleyo epropathi enomgangatho ophezulu wokuqonda. Akunjalo kuphela ukusebenza kwemveliso kufikelele kwinqanaba le-PEEK yangaphandle, kodwa kunye nezixhobo eziluhlaza kunye nezixhobo zonke zisekelwe e-China, ngokufanelekileyo ukunciphisa iindleko zemveliso.
Okwangoku, ishishini laseTshayina lePEEK likhulile ngokwentelekiso, linomgangatho ofanayo kunye nemveliso njengabenzi bangaphandle, kwaye ixabiso lisezantsi kakhulu kunemarike yamazwe ngamazwe. Into ekufuneka iphuculwe bubutyebi obahlukeneyo bePEEK.
IVictrex yayilicandelo le-ICI yaseBritane de yaye yasolwa.
Yaba ngumvelisi wokuqala wePEEK wehlabathi.
Ukusetyenziswa kwePEEK
1. Usetyenziso lwe-aerospace: ukutshintshwa kwe-aluminiyam kunye nezinye iintsimbi kwiindawo zenqwelo-moya, kwiindawo zokubeka ibhetri yerokethi, iibholiti, iintongomane kunye namalungu eenjini zerokethi.
2. Ukusetyenziswa kwintsimi ye-elektroniki: ifilimu ye-insulation, i-connector, ibhodi yesekethe eprintiweyo, isixhumi sokushisa okuphezulu, isiphaluka esidibeneyo, i-cable coil skeleton, i-insulation coating, njl.
3. Ukusetyenziswa koomatshini beemoto: iibheringi zeemoto, iigaskets, izitywini, ii-clutches, iibhuleki kunye neenkqubo zomoya. Nissan, NEC, Sharp, Chrysler, GENERAL Motors, Audi, Airbus kunye nabanye baye baqala ukusebenzisa izinto eziphathekayo ngobuninzi.
4. Izicelo kwintsimi yezonyango: amathambo okwenziwa, isiseko sokufakelwa kwamazinyo, izixhobo zonyango ezifuna ukusetyenziswa ngokuphindaphindiweyo.
