I-vs.peek

I-Abstract: I-Pom kunye ne-Peek zizinto ezimbini zePolymer. Zahluke kakhulu kwiinkalo ezininzi. Oku kulandelayo luphawu olupheleleyo lwezi zinto zimbini: Ubume kunye nolwakhiwo, iipropathi zoomatshini, iipropathi zekhemikhali, iipropathi zemichiza, iindawo zokusebenza, iindawo zokusebenza, njl.

Izithako kunye nolwakhiwo:

I-Polyoxymethylene (i-POM) yi-thertoline ye-thermoplastic polymer polymermer evela kwiFomaldehyde (Ch2o) monomer. Imixokelelwane yayo yemolekyuli inamalungiselelo a-odoweyo, inika iipropathi ezibalaseleyo zoomatshini kunye neepropathi zokulungisa.

I-Polyoretherketone I-molecular i-molecular inzima kune-POM kwaye inobungqola kunye nokuba neqhinga, kuyenza iphumelele ngokupheleleyo kubushushu obuphezulu kunye noxinzelelo lomatshini.

Ukuziphatha koomatshini:

I-POM ineendleko zokunxiba kakuhle, ingqongqo ephezulu kunye nokunganyangeki kwempembelelo. Amandla ayo, ubukhali kunye nokunxiba ukunyangwa kungabakhulu kwiintsimbi kwizicelo ezininzi. Nangona kunjalo, ukuchasana nobushushu obuphezulu kunye nokuxhathisa iikhemikhali kubuthathaka kakhulu.

I-Peek ilunge ngakumbi ukunyanga kobushushu kwaye inokusetyenziswa ngokuqhubekayo nge-250 ℃ ixesha elide. Ukongeza, i-Peek inomgangatho obalaseleyo wekhemikhali kwaye inokusetyenziswa kwiindawo ezininzi zoncedo. Nangona kunjalo, i-Peek ineepropathi ezingekho mgangathweni kwaye ifuna ubushushu obuphezulu kunye noxinzelelo.

Umsebenzi we-thermal:

Ipropathi ye-thermal ye-POM kunye ne-peek bahluke kakhulu. I-POM inendawo ethambileyo yokunyibilika, malunga ne-170 ° C, kunye nobushushu obugqwethekileyo ubushushu abangama-90 ° C. Oku kuthetha ukuba kumaqondo obushushu aphezulu, i-Pom iqhele ukungcungcutheka.

I-Peek inendawo ephezulu yokunyibilika, malunga ne-340 ° C, kunye nobushushu obugqwethekileyo ubushushu ukuya kuthi ga kwi-230 ° C. Ke ngoko, i-Peek iZinzile ngakumbi kune-Pom kwiindawo zobushushu obuphezulu.

Ukungaxhathisi kwamachiza:

I-POM inabachasi beekhemikhali kwimichiza enjenge-alcohols, amaKenes, kunye nee-Esters, kodwa azimelana ne-Acids, iziseko ezomeleleyo, kunye ne-hydrocarbons eqinileyo. Kuba kwezinye iindawo ezinokubakho, ukusetyenziswa kwe-POM kunokuncitshiswa.

I-Peek inomthi wokuxhathisa iikhemikhali zekhemikhali kwaye inokumelana nokuhlaselwa kwee-acids, ialkalis, iityuwa kunye nezinyibilikisi zezinto eziphilayo. Oku kwenza ukuba ukhetho olufanelekileyo kwizicelo ezininzi zeshishini.

Iipropathi zombane:

Akukho mahluko mninzi kwiipropathi zombane ze-POM kunye ne-peek. Zonke zinepropathi egqwesileyo kunye nokuxhathisa i-voltage kwaye zinokusetyenziswa kwimihlaba ye-elektroniki kunye nemibane. Nangona kunjalo, banayo iqhinga elibi lombane kwaye alungeleleki kwizicelo ezifuna ukwenziwa kombane.

Umsebenzi wokuSebenza:

I-Pom inepropathi ebalaseleyo yokulungisa. Kulula ukuyifumana inaliti yejen, ukuphuma nokubetha. Ukongeza, i-POM inolwelo oluhle kwaye inokuvelisa iimveliso ngeenkcukacha ezintsokothileyo.

Xa kuthelekiswa, i-Pek ineeqondo lobushushu eziphezulu kwaye ifuna uxinzelelo oluphezulu. Ke ngoko, i-Pek inzima ukuyiqhubela phambili kwaye iindleko ziphezulu. Nangona kunjalo, i-Peek inokuqhutywa ngenaliti yokubumba, ukuphuma kunye nokuvuthuza.

Iindawo zesicelo:

Kuba i-Pom kunye ne-Peek ineepropathi ezahlukeneyo kunye ne-thermal, amasimi awo wesicelo ayahlukile. I-POM isetyenziselwa ukwenziwa kwamalungu angazivumeliyo i-inxilisayo njengeegiya, iibheringi, kunye nezixhobo zonyango kunye neenxalenye zemoto.

I-Pek isetyenziswa ikakhulu kwizinto kubushushu obuphezulu kunye neemeko zoncedo, ezinjengamacandelo akwicandelo le-aerospace, ivalves kwishishini lekhemikhali, i-Peek linokusetyenziswa kwimveliso yemveliso ye-3D.

Ukuphamba, zombini i-POM kunye ne-POM zizinto ezibalaseleyo zePolymer kunye neepropathi zabo ezizodwa kunye neenkalo zezicelo. Ukukhetha kwezinto kuxhomekeke kwiimfuno ezithile zesicelo kunye neemfuno.
