Chirevo chekuvanzika: Kuvanzika kwako kwakakosha kwazvo kwatiri
Pps mapurasitiki uye peek mapurasitiki: kupisa kudziya kuenzanisa uye mechancal zvivakwa kuenzanisa, ndiani ari nani?
Kune zvinhu zviviri zvepolymer, PPS uye peek, pane zvimwe zviri pachena pakati pavo. Kutanga, maererano nenongedzo yekunyungudika, pps ine inonyungudika ye80 ° C, nepo peek ine poera ye140 ° c. Izvi zvinoreva kuti peek ine yepamusoro inopisa yekupesana munzvimbo dzakasimba dzepamhepo.
Kechipiri, maererano nesimba rekutarisa, PPS ine 40% girazi fiber yakawedzerwa ine simba regumi negumi neshanu, nepo peek mumamiriro ezvinhu akafanana anoratidza kusimba kwe 115mpa. Izvi zvinoratidza kuti peek iri nani zvishoma nezvishoma pamasimba emasimba emasimba.
Kupfuurirazve, kuenzanisa hupfumi hwematombo, hupfu hwezana zana apo peek ane kuomesa kwe105, zvinoreva kuti peek inonyanya kukwirira maererano nekuomerwa kwekuomesa musoro.
Chekupedzisira, maererano nekumberi kwenguva refu tembiricha, pps ine tembiricha yebasa ye250 ° C kana zvishoma, nepo peek ine tembiricha yebasa ye250 ° C kana zvishoma. Izvi zvinoratidza kuti peek ine yepamusoro yekupisa kupesana munzvimbo dzakakura dzekushisa.
Naizvozvo, kunyangwe zvese zvirongwa uye peek zvakakwirira-mashandiro engineering mapurasitiki, ivo vane yavo yekuita maitiro. Mune zvimwe zviitiko, senge mumamiriro ekupokana kana kana tembiricha isina kukwirira, PPS inogona kushandiswa panzvimbo peek, nekudaro ichidzora mitengo. Nekudaro, mune zviitiko uko peek chete inogona kushandiswa, pps yakaoma kunyatso kutsiva, kunyanya munzvimbo dzakakwirira-tembiricha.

Chirevo chekuvanzika: Kuvanzika kwako kwakakosha kwazvo kwatiri
Zadza rumwe ruzivo kuti ugone kuwirirana newe nekukurumidza
