Peei vs.peek

PEI uye peek inonyanyopurika-mashini engineering mapurasitiki akafanana nenzira dzakawanda, asi zvakare ane mamwe misiyano.

Polyether Etone (Peek) : Peek is a thermoplastic engineering mapurasitiki ezvivakwa neanopfuura makumi matanhatu Simba reMuchina. Iyo ine chinongedzo chekunyungudika kusvika ku 342 ° c uye tembiricha yemadhiraivhi yekushambadzira inosvika ku25 ° C, iyo inoita kuti iite zvakanaka munzvimbo dzakakwirira-tembiricha. Uye zvakare, peek ine yakanaka kwazvo yemagetsi insulation zvivakwa uye murazvo unodzora zvivakwa.

Polyether Etone Ketone Coplymer (PEI) : PEI idzo coplymer yePeek uye nhamba yevamwe polymers, kazhinji inosanganisira 35-45% peek uye 65-75% vamwe polymers. Zvivakwa zvePEI zviri pakati peiyo peek enyanzvi uye dzevanyori veinjiniya mapuranga, et6, etcc. . PEI ine yakakwira yekudzikama, simba rekusimba uye nemakambani ezvekushandisa kwemagetsi.

Peek uye Pei vakasiyana mune zvinotevera zvinhu:

1. Kuumbwa Kwekudzika: Kunyangwe iyo yekushomeka kwechidhori yePei nahwo yakanyanya kukwirira, kugadzikana.

Makemikari zvivakwa zvakagadzikana, nepo peek ichapfekedza, kuyerera uye oxidize pane yakakwirira tembiricha.

2. PEI Zvivakwa: PEI iri nani zvishoma kupfuura peek mune zvimwe zvekushandisa, semuenzaniso, simba rePEI uye kuomarara kwakakwirira zvishoma pane peek. Nekudaro, musiyano uyu hauna kukosha mune zvakawanda zvekushandisa, uye nekuda kwekunyungudika kwepamusoro hwekunyungudika nekunyungudika, kunogona kuve kwakanyanya kubatsira mujekiseni rekuumba.

3. Mutengo: Mari yePEI inowanzo kuve yakakwira kupfuura iyo yehukuru nekuda kwehukama hwehukama hwekugadzira maitiro ekugadzira uye mutengo wepamusoro wezvinhu zvisina kugadzirwa. Nekudaro, uyu mutsauko ungangogadziriswa mukugadzirwa kukuru.

4. High tembiricha yekushisa: imwe yemisiyano huru pakati pepeek uye pei ndiyo yavo yakasiyana morphological zvivakwa. PEI id Amorphous, nepo peek ise-crystalline (uye ine ese amorphous uye crystalline matunhu). Izvi zvinogona kuratidzika senyaya isingabatsiri, asi ine chiitiko chakakosha pakuita kwekutyisidzira tembiricha, kunyanya pamusoro pegirazi tembiricha yezvinhu zvese.

Peek ine girazi transition tembiricha (TG) yeanoda kusvika 289f Kupisa tembiricha kazhinji kunowanzo kutaurwa kunge 340 degrees Fahrenheit. Izvi zvinodaro nekuti kuTg yezvinyorwa, matunhu emorphous akapfava kana rabhayeti, nepo matunhu emakristenle asina kubatwa. Naizvozvo, iyo yakanyanya kushandiswa service tembiricha yeAmorphous zvinhu zvinoenderana zvishoma.

5. Zvivakwa zvemagetsi: Nekuda kwezvekugadzira zvemagetsi, zvinhu zvese zvinoshandiswa zvinoshandiswa zvakanyanya mune zvemagetsi zvikamu, kusanganisira semicononductor zvigadziko uye zvinobatanidza magetsi. PEI ine yakakwirira yekudyira simba rezvekutengeserana ripi zvaro renzvimbo yeTermoplastic at 830 v / mil (maringe neASTM D149) (kana kana inogona kutaura). Peek ine yakasarudzika dielectric Simba re 480 v / mil. Peek inoshuma iyo dielectric Simba re 480 v / mil. Zvekushandisa zvinoda kuderera mazinga ekupokana, mamakisi emidziyo yekunyora uye antistatic zviripo.

6 Peek inoshandiswa zvakanyanya mune pasi uye gasi zvikumbiro nekuda kwekuramba kwayo kumakemikari ane hosha kusanganisira H2S. Pi peiwo iri zvakare ichiramba kune akasiyana emakemikari, its brittleness inokanganiswa nekuda kwekunetseka kwemamiriro ekunze.Pamusoro

PEI yakaratidzwa kuratidza shanduko dzisingakwanisi kuita midziyo yemuchina mushure mekuratidzwa kwekunze kweUV.Peek inoenderana nemhedzisiro yezvimiro zvidiki, zvingangoita mukati meimwe, uye inogona kuderedzwa nekubatanidzwa kwe mavara ezvipfadzo. Iyo radiation kuramba kwakasiyana-siyana pregement Injiniya mapurasitiki adzidzidzwa uye peek (uye imwe polyaryletherketones) yakawanikwa kuratidzira huwandu hwepamusoro hwekurwisa radiation kuramba.

7. Pfeka performance, kupisa, maindasitiri ekuteerera uye mutengo wehama

Zvekupfeka zvikumbiro, peek zvinowanzodiwa nekuda kwekuwedzera kwekupedzisira pv kugona uye zvakanyanya kuderera kupfeka mitengo. Specialty Bearing Grads yePeek inosanganisira mafirita eFiller ine akasiyana maficha ePTFE, Carbon fiber uye graphi fiber uye graphite poda kuderedza kupokana uye kuwedzera kupfeka hupenyu.

8 PEI anodzikiswa ku 5va at 1.6mm uye ane yakakwira kudzora oxygen index (Li) ye77%. Standard peek uye peei mamakisi ari fda anoenderana. Ose ari maviri anowanikwa nyore nyore muUSP kirasi vi-inoenderana mamakisi ezviratidzo zvekurapa. Izvi zvinhu zvinogona kusangana nezvimwe zvevamwe maindasitiri zvinodiwa, asi rondedzero yakazara inopfuura chiyero chechinyorwa chino. Zvakakodzerawo kucherechedza kuti zvakasikwa PEI imberlent Amber ruvara, nepo zvisikwa zvevatambi isa opaque tan ruvara. Zvese zvinhu zvinowanikwa mune zvakasikwa uye matanda matanda nemashiti. Yakasikwa ine ruvara rwepeek tubing inowanikwa zvakare nyore.

Pakupedzisira, peek profiles inodhura kanenge katatu kakawanda sevanotarisana navo. Nekudaro, zvezvisviniro kana mhete (kunyanya madhiri akakura), uyu mutsipa mutsauko unowanzorerwa nekuwanika kwakawanda kwekutakura kwembambo. Ndinovimba iwe wawana zviri pamusoro zvinobatsira mukusiyanisa pakati pePei naPeek, uye nepo zvinhu zvese zvinopesana zvakaringana, zvivakwa zvavo zvinowanzoitika kuti zviite kuti mumwe mushandisi akakodzera pane imwe yekupedzisira yekushandisa.
