Pei vs.peek

I-Pei kunye ne-Peek bangamabini amaplanga amaninzi oqulunqa olusebenzayo olufanayo ngeendlela ezininzi, kodwa ikwanomahluko ophambili.

I-Polyteether Ether Ketone (Pek) : I-Peek): I-Peks yiplastiki yobunjineli be-thermoplastic ene-50% diols.peames.ideek inobushushu obuphezulu, uzinzo lwekhemikhali kunye amandla omatshini. Inendawo yokunyibilikisa ukuya kuthi ga kwi-342 ° C kunye neqondo lokungalunganga le-thermal ukuya kuthi ga kwi-340 ° C, eyenza ukuba yenze kakuhle kwiindawo zobushushu obuphakamileyo. Ukongeza, i-Pek ineepropathi ezibalaseleyo zombane kunye neepropathi ezihlawulelweyo.

I-Polyteether Ether Ketone Copolymer (Pei) : I-Pei yi-Copolymer ye-Peek kunye neqela lezinye iipolimers, zihlala zinama-35-40% i-65-75% ezinye iipolymers. Iipropathi ze-PEI ziphakathi kwezo ze-Peek kunye nezo zePlastiki zobunjineli bezithethe zemveli, ezinje nge-PA66, i-PAYE, njl. . I-PEI inozinzo oluphakathi okuphezulu, uzinzo lwamachiza kunye noomatshini, kunye neepropathi ezifanelekileyo zokuhlawula umbane kunye neepropathi ezihlawulelweyo.

I-Peek kunye ne-Pei zahlukile kule miba ilandelayo:

1. Uzinzo lobushushu uzinzo.

Iipropathi zeekhemikhali ziyazinza, ngelixa i-piek iya kuthamba, ukuhamba kwaye iqhume kumaqondo obushushu aphezulu.

2. IPREST PROSTRTUTER: I-PEI ilunge ngakumbi kune-Peek kwezinye iipropathi zoomatshini, umzekelo, amandla e-peile ka-pei kunye nokuqina komzimba ziphezulu kakhulu kune-Peek's. Nangona kunjalo, lo mahluko awubalulekanga kwizicelo ezininzi, kwaye ngenxa yokunyibilika kwenqaku eliphezulu le-Pekk kunye nolwelo oluhle, kunokuba luncedo ngakumbi kwinaliti.

3. Iindleko: Ixabiso le-PEI lihlala lingaphezulu kunezo ze-Peks ngenxa yobunzima benkqubo yokuvelisa kunye neendleko eziphezulu zezinto ezingafunekiyo. Nangona kunjalo, lo mahluko unokubakho kwimveliso yobuninzi.

4. Ukusebenza kobushushu obuphezulu: Omnye umahluko ophambili phakathi kwe-Peek kunye ne-Pei ziimpawu zazo ezahlukeneyo ze-mor. I-Pei yi-amorphous, ngelixa i-peek i-semi-clestalline (kwaye iqulethe zombini iindawo ze-amorphous kunye ne-crystalline). Oku kunokuvakala njengenyaniso engenamsebenzi, kodwa inefuthe elibonakalayo kwintsebenzo kumaqondo obushushu aphakamileyo, ngakumbi ngaphezulu kweqondo lokushisa leglasi yeglasi yempahla nganye.

I-Peek inamaqondo obushushu eglasi (i-TG) malunga ne-289f, ngelixa i-Pei ine-420f, kodwa i-Peek isetyenziswa ngokungaguquguqukiyo kwizicelo zeqondo lobushushu), ngelixa i-Ultem iqhubela phambili Ubushushu bokusebenza buye banikwa ingxelo njenge-340 degrees fahrenheit. Kungenxa yokuba kwi-TG ye-TG yezinto, iimimandla ze-amorphous zithambisa okanye irabha, ngelixa imimandla yekristali ayichaphazeleki. Ke ngoko, olona qondo lobushushu olwenziweyo lwezinto ze-Amorphous lilinganiselwe ngokulinganayo.

5. Iipropathi zombane: Ngenxa yeepropathi zabo zombane, zombini ezi zinto zisetyenziswa ngokubanzi kwizinto ze-elektroniki, kubandakanya iziseko zovavanyo ze-semicondcucy kunye nezixhobo zombane. I-Pei inowona mandla mazulu aphezulu kaDeectric A3 I-Peek inamandla axekileyo ka-480 v / Mil. I-Peek inika ingxelo yamandla eDelectric as 480 v / Mil. Kwizicelo ezifuna amanqanaba asezantsi okuxhaphakala, amabakala amanani aqingqiweyo anqabileyo kwaye izixhobo ze-antistatic ziyafumaneka.

6. Ukungaxhathisi bobuchule: Zombini ezi zinto zichasene ne-steam kwaye zilungele izahlulo zonyango ezinokuphinda zifumaneke. I-Peek isetyenziswa ngokubanzi kwizicelo zeoyile zeoyile negesi ngenxa yokungaxhathisi bazo kwiikhemikhali ezinzima kubandakanya i-H2S. Ngelixa i-Pei ikwanyangeka kuluhlu olubanzi lweekhemikhali, ubuchwephesha bayo bwenza ukuba bube sengozini yokufumana uxinzelelo lwe-ramatic.

I-Pei ibonisiwe ukuba ibonakalise utshintsho olungaqondakaliyo kwiipropathi zoomatshini emva kokuvezwa kwe-UV kwi-radiation ye-UV, kodwa idatha ibonisa ukuba i-properties ye-coperties incinci, kwaye inokuncitshiswa ngokufakwa kwe I-pigment enemibala. Ukuchasana kwe-radiation yeeplanga ezahlukeneyo zokusebenza kweplanga ifundwe kwaye i-Peek (kunye nezinye iPolyaryletones) zifunyenwe ukubonisa amanqanaba aphezulu okunganyangeki kwe-radiation.

7. Yenza intsebenzo, ukuvutha kommiselo kunye neshishini kunye neendleko

Ukunxiba izicelo, i-Peek ihlala ikhethwa ngenxa ye-PV yayo ephezulu ye-PV kwaye iphantsi kwexabiso eliphantsi. Ibakala elikhethekileyo le-Peek liquka iipakethi zefilitha ngamanqanaba ahlukeneyo eefilithe ze-ptfe, i-carbon fiber kunye ne-picbon fiber kunye negraphite powder ukunciphisa uxinzelelo kwaye udlulise ubomi.

8. I-Flame Reardiser: Zombini ezi zixhobo zedangatye ziyibuyisa kwaye zigcine i-UL 94 V-0 i-vfom yokuqina kwamacandelo amanqatha. I-Pei ihlawulwe kwi-5va kwi-1.6mm kwaye inesalathiso seoksijini ephezulu (i-LOI) ye-47%. Amanqanaba asemgangathweni asemgangathweni we-Peek kunye ne-PeI ahambelana ne-FDA. Zombini zifumaneka ngokulula kumabakala e-USP ye-USP ehambelana nezicelo zonyango. Ezi zixhobo zinokuhlangabezana nezinye iimfuno zokuthotyelwa kweshishini, kodwa uluhlu olupheleleyo lungaphaya komda weli nqaku. Kukwakufanelekile ukuba uqaphele ukuba i-pei yendalo yi-translust amber, ngelixa i-peek yendalo ingumbala we-opaque. Zombini ezi zinto ziyafumaneka kwiintonga zendalo nezemvelo kunye namashiti. I-tubing yendalo yendalo ikwafumaneka ngokulula.

Ekugqibeleni, iiprofayili ze-pekiki zixabisa malunga nezihlandlo ezithathu njengabalingane babo. Nangona kunjalo, amatywina okanye amakhonkco (ngakumbi ububanzi be-seameter), lo mahluko amaxabiso ahlala ethotyelwa kukufumaneka kobubanzi be-tubing ye-peek. Ngethemba lokuba uyifumene le nto ingentla ekwahlukileyo phakathi kwe-Pei kunye ne-Peek, kwaye ngelixa zombini izixhobo zifundisa amaqondo obushushu aphezulu kwaye ziqhele ukwahluka ngokwaneleyo ukwenza umntu asetyenziswe ngumntu othile.
