Chirevo chekuvanzika: Kuvanzika kwako kwakakosha kwazvo kwatiri
Abstract: pom uye peek ndidzo mbiri dzakasiyana dzepolymer. Ivo vakasiyana zvakanyanya mune zvakawanda zvinhu. Izvi zvinotevera kuenzanisa kwakazara kwezvinhu zviviri izvi: Kuumbwa uye chimiro, zvimiro zvekugadzira, zvimiro zvemakemikari, kuramba zvinhu zvemakemikari, zviitiko zvemagetsi, nzvimbo dzekushandisa, nezvimwe.
Zvinongedzo uye chimiro:
PolyoxyMethylene (POM) is a thermoplastic crymen polymer polymerized from formaldehyde (Ch2o) monomer. Maketeni ayo anonyora ane gadziriro yakanyanya kuraira, ichipa iyo yakanaka manhamba uye kugadzirisa zvivakwa.
PolyeethetherTheetone (peek) ndeye semi-crystalline polymer yakagadzirwa nePolymerization maitiro eEthetsone monomer. Chaiyo molecular yakanyanya kuoma kupfuura pom uye ine kuomarara uye kuomarara, ichiita kuti zviite zvakanakisa pasi pekudziya kwakanyanya uye kumanikidza kumanikidza.
Maitiro maitiro:
POM ine yakanaka kupfeka kurwisa, kuomarara kwakanyanya uye kukanganisa kuramba. Simba rayo, kuomarara uye kupfeka kuramba kwakakwirira kune simbi mune akawanda mashandisiro. Nekudaro, kupesana kwaro kwakasimba uye kurwisa kwemakemikari hazvina kusimba.
Peek ine yakanaka kwazvo kupisa kupisa uye inogona kushandiswa zvichiramba zvichienderera na250 k kwenguva yakareba. Uye zvakare, peek ine yakanakisa makemikari uye abrasion kuramba uye inogona kushandiswa munzvimbo dzakawanda dzinodzora. Nekudaro, peek ine zvivakwa zvisina kunaka zvekuita uye zvinoda kupisa kwakanyanya uye kudzvinyirira.
Maitiro ekupisa:
Iyo inopisa zvivakwa zve pom uye peek yakasiyana kwazvo. Pom ine poindi yakadzika yekunyungudika, anenge 170 ° C, uye kupisa kukanganisa kwekutyisa kwegumi nenomwe c. Izvi zvinoreva kuti pakupisa kwakanyanya, pom zvinowanzoitwa kushatirisa.
Peek ine poindi yakakwira inonyungudika, anenge 340 ° C, uye kupisa kupisa tembiricha inosvika 230 ° c. Naizvozvo, peek inonyanya kugadzikana pane pom mune yakanyanya tembiricha nzvimbo.
Kumakemikari kurwisa:
POM ine yakanaka yemakemikari kupokana kunge masimbi akadai seanobiridzira. Nekuti mune dzimwe nharaunda dzinodzora, kushandiswa kwe pom kunogona kudzikiswa.
Peek ine yakanaka yemakemikari kuramba uye inogona kuramba kurwiswa kweakanyanya acids, alkalis, munyu uye organic sol sol. Izvi zvinoita kuti peek isarudzo yakanaka mumakemikari emakemikari eindasitiri.
Zvivakwa zvemagetsi:
Iko hakuna mutsauko wakawanda mumidziyo yemagetsi ye pom uye peek. Ivo vese vane zvakanakisa zvekusimbisa zvinhu uye kupokana nevoltage uye kunogona kushandiswa muminda yemagetsi uye yemagetsi. Nekudaro, ivo vane magetsi asina kunaka maitiro uye haana kukodzera kuti zvikumbiro zvinoda magetsi maitiro.
Kugadzirisa Performance:
Pom ine zvakanakisa kugadzirisa zvinhu. Nyore ku jekiseni mold, kubuda uye kuridza kuumbwa. Mukuwedzera, pom ine yakanaka fluidity uye inogona kuburitsa zvigadzirwa zvine zvimwe zvakaoma.
Mukuenzanisa, peek ine yepamusoro yekugadzirisa tembiricha uye inoda kudzvinyirira kwakanyanya. Naizvozvo, peek yakanyanyisa kuoma kuita uye mutengo wakakwira. Nekudaro, peek inogona kuongororwa kuburikidza ne jection kuumbwa, kubuda uye kurova kuumbwa.
Nzvimbo dzekushandisa:
Sezvo pom uye peek ine zvimiro zvakasiyana uye zvekupisa zvivakwa, minda yavo yekushandisa zvakare yakasiyanawo. POM inonyanya kushandiswa kugadzira zvikamu zvekupfeka zvakadai semagiya, fani, uye zvinobata, pamwe nemidziyo yekurapa uye zvikamu zvemotokari.
Peek inonyanya kushandiswa mune zvikamu mune yakanyanya tembiricha uye zvakashata munda, maCours uye neishanduri yemakemikari, etc.CE, peek inogona zvakare kushandiswa muminda inobuda sekugadzira 3D kudhinda kwekutanga
Kuti upedze, zvese pom uye peek inonakisa polymer zvinhu neyavo chaiyo yakasarudzika zvinhu uye minda yekushandisa. Iko kusarudzwa kwezvinhu kunoenderana nechinhu chaicho chekushandisa uye zvinodiwa.
