Chii chinonzi PPO zvinhu? Kuongorora kwakadzama kwezvivakwa uye mashandisirwo epolyphenylene ether
PPO Material Overview
PPO, inozivikanwa sePolyphenylene Oxide, inonzi thermoplastic engineering plastic ine yakanakisa mechanical properties uye chemical resistance.Kubva payakatanga, PPO material yakashandiswa zvakanyanya mundima dzakasiyana siyana dzemaindasitiri nemhando dzayo dzakasiyana, uye yave chinhu chakakosha mumaindasitiri emakemikari, emagetsi nemagetsi.
Kemikari chimiro uye zvakakosha zvimiro zvePPO zvinhu
Iyo molecular structure yePPO ine benzene mhete dzakabatanidzwa ne ether bonds, iyo inopa yakanakisa yemuviri uye makemikari properties.PPO zvinhu zvine zvakanakisa kupisa kupisa, girazi rayo rekuchinja tembiricha inenge 210 ° C, uye inogona kuchengetedza yakanaka mechanical properties pakupisa kwepamusoro.PPO inewo yakanakisa magetsi ekudzivirira zvinhu uye kunyura kwemvura shoma, iyo inokodzera kushandiswa kunoda maitiro emagetsi epamusoro.
Zvakanakira uye kuipa kwePPO zvinhu kuongororwa
Iyo yakakura mukana wePPO zvinhu ndeye yakanakisa makemikari kuramba uye yakagadzikana yemuviri zvimiro. Munzvimbo dzeasidhi uye alkali, PPO inoratidza kugadzikana kwakanakisa, saka inowanzoshandiswa sechinhu chinopesana necorrosion mumakemikari emidziyo.PPO's abrasion resistance uye dimensional stability inoitawo kuti ishandiswe zvakanyanya muzvikamu zvema mechanical.
PPO zvinhu zvakare zvine zvimwe zvinogumira. Nekuda kwekunyanya kunyungudika kwayo, izvo zvinodikanwa zvePPO zvinonyanya kuomarara, zvinoda tembiricha yepamusoro uye magadzirirwo eforoma. kuoma kwePPO kwakadzikira, uye zvinhu zvakachena zvePPO zvinowanzoita brittle kutsemuka pane tembiricha yakaderera, saka mune mamwe maapplication inowanzoshandiswa mumisanganiswa nezvimwe zvinhu kuvandudza kushanda kwayo kwese.
Nzvimbo dzekushandisa dzePPO zvinhu
PPO zvinhu zvine huwandu hwakasiyana hwekushandisa mumaindasitiri akati wandei. Mumagetsi emagetsi nemagetsi, PPO inoshandiswa zvakanyanya mukugadzira zvinhu zvemagetsi, zvakadai semapulagi, mashizha uye mabhokisi ekusangana, nekuda kwehutano hwakanaka hwemagetsi ekudzivirira.PPO zvinhu zvinoshandiswawo muindasitiri yekugadzira motokari yezvikamu zvehutsi, sezvo kupikisa kwayo kumafuta uye kunyura kwemvura yakaderera kunovimbisa kugadzikana munzvimbo dzakaoma.
Muindasitiri yemakemikari, PPO's corrosion resistance inoita kuti ive yakakosha kumidziyo yakadai semapombi, pombi miviri uye mavharuvhu.PPO inoshandiswawo mukugadzirwa kwezvimwe zvikamu zvemagetsi zvinoda kugadzikana kwepamusoro, senge magiya nemabhengi.
PPO zvinhu zvinogadziridzwa uye kuvandudzwa kweramangwana
Kuti tikunde zvimwe zvipimo zvezvinhu zvakachena zvePPO, vaongorori vakazvigadzirisa nekuzvisanganisa nemamwe mapolymer kana kuwedzera mafiller.PPO/PS mablends chinhu chakajairika chakagadziridzwa chine kusimba kuri nani uye kugadzirisa. Sezvo tekinoroji ichiramba ichifambira mberi, PPO zvinhu zvakagadzirirwa kuwanda kwekushandisa mune ramangwana, kunyanya mumamiriro ekukura kuri kudiwa kwemapurasitiki anoshanda zvakanyanya.
Summary
Chii chinonzi PPO zvinhu? Iyo ipurasitiki yeinjiniya yepamusoro-soro ine yakanakisa kupisa kupisa, makemikari kuramba uye magetsi ekudzivirira emagetsi. Kunyangwe mamwe matambudziko ekugadzirisa uye kuomarara, PPO ine nzvimbo muindasitiri yemazuva ano iyo isingagone kufuratirwa kuburikidza nekugadzirisa zvine musoro uye kushandisa. Mune ramangwana, nekuenderera mberi kwekuvandudza tekinoroji yezvigadzirwa, PPO ichashandiswa zvakanyanya uye zvivakwa zvayo zvicharamba zvichigadziriswa.
