Ulwakhiwo kunye nokubumba ukuqhubekeka kwe-polyet ether ethetoe

I-Polyteether Ether Ketone (i-Pek) yi-Semi-Criestalline, i-farmic ye-polymer polymer ephuhliswe ngamacandelo emizi-mveliso yaseBritani (i-ICI) ngo-1978, nge-ether Bond, i-Arbonyl iqhagamshelwe kwi-TermoPistic Ultra online Iplasitiki yobunjineli. Isakhiwo semolekyuli se-chain ephambili iqulethe inani elikhulu le-Bezene amakhonkco, eyakhe i-COCS ithambile, i-Belene iRingser Sering inyameko. Iqhina lithambile, kwaye amakhonkco amabini e-Benzene anendawo enkulu yokuthintela ngokufanelekileyo ukukhusela i-COBS ukuba itshatyalaliswe, i-atom ye-atom ye-p kunye ne-Carbonyl ye-P-π i-π i-π ye-P-π ne-π ingqungquthela. Ezi mpawu zolwakhiwo zinika i-Peek kule ndlela ilandelayo.

Iipropathi ze-peek

I-Polyteether Ether Ketone (i-peek) ye-therstalline ye-thertalline ye-thermoplastic, ubushushu beglasi yeglasi ye-143 ℃, iqondo lokungavisisani, ilangatye, i-Acid kunye ne-Hydrolysis Ukunganyangeki , Ukuxhathisa i-Abrasion, ukuchasana nokungakhathali, ukuxhathisa i-Irradication kunye ne-Radioudies yeyona nto iphambili kuyo yonke iplastiki, i-oxygen Index iphakamile, i-qubinal Indet yomsi incinci kwaye ingenabungozi. Kwiimeko ezininzi, kunokwanela ukutshintsha intsimbi, isabelo, i-ceramic kunye nezinye izinto.

I-1.IPRECTINGE ze-1.Mthembical

I-Peek Creep kunye nokuchasana nokungakhathali kulungile. Iglasi ye-fiber eqiniswe kwaye i-carbon fiber yomeleleyo kwaye engaqinisekanga xa ithelekiswa namandla kunye nemodyuli iphezulu, amandla aphezulu kakhulu kuneqondo lokutshintsha kweglasi, amandla kunye nomoda wokwehla. I-Peek kwi-Crystalline Polymers kwindawo yokunyibilika kunye neqondo lokushishina leglasi liphezulu kakhulu, ngo-200c okanye ngaphezulu, kodwa sisakwazi ukugcina amandla aphezulu kunye nomodoko. Ukongeza, i-Peek inomlinganiso ophantsi wokuxabana kwaye inxibe uluhlu olubanzi lwamaqondo obushushu kwaye unokumelana nesenzo esiphindaphindiweyo somthwalo ophakamileyo.

Itheyibhile ye-1-1 Iipropati zamabakala aqhelekileyo okuqhelekileyo

Umsebenzi wokunganyangeki

I-Peek ifanele ukuxhathisa ubushushu. Iqondo lobushushu ixesha elide ukuya kuthi ga kwi-240 ℃. Umlinganiso we-thermovmictric ye-thedrm ye-thermitha yokunciphisa umzimba ibonisa ukuba i-400 ℃ ilahleko yesisindo ye-0%; I-500 ℃ i-2.5%; Ilahleko engama-600 ℃ inyuswe kwi-59%.

Enganyanisekanga i-peek kunye ne-fiber fiber ye-fiber okanye i-carbon fiber yomeleza i-Peek, emva kokuba i-1000 HIGS APGE GIRD, amandla e-thenf ayincitshiswa. I-Peek Lirated Lire Sire Ubushushu gadalala iboniswe kwiTheyibhile 1-2, ihlala ikwi-220 ℃ Inkonzo yenkonzo engaphezulu kwe-6000H.

Olu phawu luyenza ukuba kuthathelwe ingqalelo ukhetho lokukhetha i-thermoforation, kunye ne-aefigeal kunye ne-aerospace kunye nezinye iiqondo lokushisa eliphezulu.

3. Ukuchasana kwamanzi ashushu

Ukuchasana namanzi ashushu kunye ne-Steam yenye yezona zinto zibalulekileyo ze-peek. Ngo-80 ℃ Ukuntywila kwamanzi ashushu 800h, amandla ayo angamathondi kunye ne-Elongile kwikhefu elingaguqukanga. I-200 ℃ Steam, amandla ayo entembekile kunye nembonakalo ayitshintshanga kakhulu, ke inokusetyenziswa kwi-Steam ixesha elide. Phakathi kwamaplanga onke amathafa asebunjini, i-Peek inolona galuphalo oluphezulu oluphezulu.

4. Iipropathi zombane

Ukuyekiswa kwevolunti ye-Peek Renn kufikelela kwi-1016ω.cm, kunye nelahleko yelahleko ye-Diecle Tangent incinci kwiindlela eziphezulu. Kwiqondo lobushushu obuphezulu, uxinzelelo oluphezulu kunye nokufuma okuphakamileyo kunye nezinye iindawo eziphantsi zisenokugcina ukufakwa kombane.

5. Ukuxhathisa kwemichiza

I-Peek ukongeza kwi-acid egxile kwi-acid, phantse nayiphi na imichiza; Kumaqondo aphezulu amaqondo obushushu, isenokugcina uzinzo lwekhemikhali. Xa kuthelekiswa nePolycarbonate, i-polyphenylene i-polysunyne ether kunye ne-polysulfone, ukumelana nemichiza ye-Peek phantsi koxinzelelo kakhulu (iTheyibhile 1-3).

Nangona kunjalo, uxinzelelo lokuqhekeka luhlala luyenzeka xa i-Peek intywiliselwa kwezinye iichemicals (umz. Ngokuphathelene noku, inokudityaniswa (umzekelo, kwi-200 degrees Celsius) ukuphucula i-crystallinity kunye nokuchasana noxinzelelo.

6. Ilangatye libuyise

I-Peek inesidima sokuzihlaziya, ngaphandle kongezwa ilangatye leflayithi 0.8 ~ 1.6 mm hick ceke ihlawulwe kwi-UL94V ~ O Inqanaba. Isixa somsi esiphantsi kwengqumbo enyanzelisiweyo sincinci kakhulu, kwaye asinazo iigesi eziyityhefu.

7. Ukunganyangeki kwe-radiation

I-Peek ineengxaki zokunganyangeki. Ukuxhathisa kwayo kwi-y-ray kwiplaterics yonke yobunjineli yeyona nto ibalaseleyo. I-Peek ithathe idosi ye (1.0 ~ 1.2) × 107) × 107 ye-y-rays ye-Y-imitha emva kokuqala kweBrittle; (0. ~ 12) × 106gy ye-β-ray ayinampembelelo kuyo.

8. Ukuzimela

I-Peek ineepropathi eziphakamileyo zokuzibonakalisa kakhulu, ezifanelekileyo kwiimfuno ezingqongqo zelingaqos eziphantsi zefonti kunye nezicelo zokunxiba ezixhaphakileyo. Ingakumbi ne-carbon fiber, igrafu, i-Pmpd ye-PTPE iDeeed Peeed idutyulwe kakhulu.

9. I-biomatise

I-Peek ayinatyhefu, ikhuselekile kwaye ingonakalisi, ihambelana neflogic. I-Imeplant-Inqanaba lemibutho yokuhlola ngaphandle kwamanye amazwe ngokungqonge ngokungqongqo kwe-ISO10993, iqhube kuvavanyo olupheleleyo lwe biomplate. Iziphumo zibonisa ukuba i-Peek yeBanga elinokwenzeka linobume be-biomatise kwaye ayinaziphumo ebezingalindelekanga.

Inkqubo yokubumba

1. Iimpawu zokuBula

I-Peek imerlt vism vissosity ngaphezulu kwe-380'C iba ngaphantsi kuxhomekeke kubushushu, kodwa ixhomekeke kakhulu kwi-Shear uxinzelelo kunye nenqanaba le-Shear. Ngamanye amagama, kuyasebenza ukwandisa uxinzelelo ukuze ufumane i-faidimis ephezulu kakhulu ngexesha lokubumba.

2. Inaliti yokubumba

Inqaku le-Peek Ling liphezulu, xa kuthelekiswa neplasitiki yobunjineli ngokubanzi, i-viscosity ye-viscosity inkulu, iqondo lobushushu liphezulu, iqondo lobushushu le-barrel lilawulwa ngama-350 ~ 400 ℃. Ngaphambi kokubumba, izinto ezibonakalayo ngokubanzi zifuna ukuba ziimeko zomiliselwe kwangaphambili, ezomisayo ze-150 ℃, 3h.

I-Peek yi-crystalline polymer, kuphela ekubunjweni ukuze isebenze ngokupheleleyo, ukuze ifumane iimveliso ngentsebenzo ebalaseleyo. Xa ubushushu obubumbayo we-150 ~ 160 ℃, iimveliso zenaliti ye-peki yi-opaque kunye nenqanaba eliphezulu le-crystallies, kodwa umphezulu onokuphezulu unokuba sisiseko esiselula; Ngelixa ubushushu obubumbayo we-180 'c, unokufumana inqanaba eliphezulu leemveliso zekristali. Ukuba inkqubo yokubumba ayinakusetyenziswa ubushushu obuphezulu, imveliso kufuneka ibe ngunyango lokuphucula i-crystallies yalo. Iimeko zonyango zeposi zihlala zingama-200 ℃, i-1 h okanye i-300 ℃, 2 imiz. Inaliti yenaliti ye-Peek inokusetyenziswa kwizixhobo eziqhelekileyo zokubumba. Kodwa ekubumbeni ubume obukhulu, obuxineneyo okanye obunzima bemveliso, kufuneka busetyenziswe kwicandelo eliphezulu kunye necandelo elifutshane lokucinezelwa kwesikhafu. Itheyibhile 2-1 lalitha iimeko zentshukumo zentsholongwane.

3.extustusion ebumbayo

I-Peek inokulungiswa ngokupheliswa kwefilimu, i-monomilament, i-ronomilaty, i-rod, i-wire ye-will kunye nenye yeemveliso zefilimu. kwaye i-polylimide ifilimu yekapton phakathi, ye-CARY I-CURDINSSURE SMORDEREREDPERE, Japan Sumachil WimilDeds, Inc. Itheyibhile 2-2 Uluhlu lweepropathi zefilimu ye-Pekk.

ITheyibhile 2 Kufuneka kuqatshelwe ukuba xa iinxalenye ezinkulu ezino-6,3 cm zilungisiwe, amanani angaphakathi kunye neendawo eziphezulu zenziwe ngenxa yoxinzelelo lwangaphakathi oluveliswe ngumahluko kumanqanaba olwenziwe ngamanqanaba. Oku kunokuphuculwa liqondo lokushisa eliphezulu litshilo (i-300 ° C, iiyure ezininzi).

4. I-Lamoting ye-GAMECH kunye ne-elektrostatic

I-Peek njenge-matrix i-wiber, kunye ne-fiber yefayibha yeglasi okanye i-carbon fiber, okanye umxube wezinto ezibini, ngokusebenzisa i-300 ℃, ukugoba i-Elasticy Auntity AMANQAKU E-TOOTION COURE (iTheyibhile 2 -4).

I-70% ye-carbon ye-carbon engafunekiyo iya kubonisa amandla aphezulu kunye nokuba namandla, amandla e-thensile nge-23 ℃ ukuya kuthi ga kwi-1540MPA, ukuqina kwe-elaistic yokufikelela kwi-130gpa. Okwangoku akukho sinyibilili sinokuphelisa i-Peek, ngenxa yoko ayinakuthiwa sisisombululo, kodwa inokusetyenziswa ngokusekwa komgubo wombane ukuze ifumane umgubo wombane, ukumelana nobushushu kunye nokuchasana kwamanzi isinyithi. Iimveliso zensimbi ze-Peek Powder.

5. Ukulungiswa kwesibini

I-Peek inokuba ngoomatshini, i-woltrasonic welding, ukubekwa, ukungqungqa kunye nezinye iindlela zokulungisa kwenqanaba lesibini. Kwakhona i-epoxy resin, i-polyurethane, i-silicone kunye nabanye abanamaphiko. Ukwenzela ukuphucula amandla aphezulu, umphezulu wamalungu unokusetyenziselwa ukuphindaphinda nge-acid.
