Chii chinonzi POE? Kuongorora kwakadzama kwezvinhu zvayo uye mashandisirwo
POE (Polyolefin Elastomer) chinhu chepolymer chinoshandiswa zvakanyanya muindasitiri yemakemikari mumakore achangopfuura. Nekufambira mberi kwesainzi uye tekinoroji uye nekuwedzera kwekudiwa kwemaindasitiri, POE inokunda muminda yakawanda nekuda kwezvivakwa zvayo zvakasiyana. Muchikamu chino, tichakurukura zvakadzama kuti POE chii, uye kuongorora zvimiro zvayo, maitiro ekugadzira uye nzvimbo dzekushandisa kubatsira vaverengi kunzwisisa kukosha kwechinyorwa ichi.
Basic Properties yePOE
Chii chinonzi POE zvinhu? Panyaya yechimiro chemakemikari, POE ielastomer yakagadzirwa kubva kucopolymerization ye ethylene ine copolymerising monomer, kazhinji α-olefin. Zvinhu zvaro zvakakosha zvinosanganisira elasticity yakanakisa, yakaderera density, kujeka kwepamusoro, uye mamiriro ekunze akanaka uye kushomeka kwekushisa. Ndizvo izvi zvivakwa zvinobvumira POE kuti ibudirire mumhando dzakasiyana dzekushandisa, kunyanya mumotokari, zvekurongedza zvinhu uye tambo sheathing.
Iyo POE Kugadzira Maitiro
Kuti unzwisise kuti POE chii, zvakakosha kutarisa maitiro ayo inogadzirwa, iyo inowanzoitwa metallocene catalyst polymerisation. Metallocene catalysts ane reactive catalysts anobvumira kunyatso kudzora kwe molecular huremu kugovera kwepolymer uye kunyudzwa kweiyo copolymer monomers. Iyi nzira inoguma nekugonesa processability uye inowirirana zvigadzirwa zvemhando dzakasiyana dzekugadzirisa nzira dzakadai sejekiseni, extrusion uye kuvhuvhuta.
Nzvimbo huru dzekushandisa dzePOE
Kana wangoziva kuti POE chii, kunzwisisa nzvimbo dzayo dzekushandisa kwakakosha pakunzwisisa kuzere kwezvinhu. Nekuda kwekusagadzikana kwayo uye kusimba, POE inoshandiswa mumhando dzakasiyana siyana dzekushandisa dzemotokari, kunyanya muzvisimbiso zvemotokari, mabumpers uye zvinhu zvemukati.PoE's low density uye pachena inoita kuti ive yakanaka yemhando yepamusoro yekurongedza zvinhu, senge firimu rekudya. Cable sheathing zvinhu zvakare yakakosha nzvimbo yekushandisa yePOE. Nekunaka kwayo kwemamiriro ekunze uye kushomeka kwekushisa, POE inokwanisa kuwedzera hupenyu hwesevhisi yetambo.
POE vs. mamwe elastomer
Kuti tinzwisise zviri nani kuti POE chii, tinogona kuienzanisa nemamwe elastomers akajairwa akadai seTPU (thermoplastic polyurethane) uye EPDM (ethylene propylene diene rubber), ine densities yakaderera, yakanakisa processability uye yakaderera mutengo. Uye kana ichienzaniswa neEPDM, POE inoita zvirinani maererano nekudzika-tembiricha kuita uye pachena. Nekuda kweizvozvo, POE inowanzo shandiswa seimwe nzira yekugonesa kuita kwechigadzirwa uye kuderedza mitengo.
Summary
Chii chinonzi POE? Zvichitaurwa zviri nyore, POE ndeyepamusoro-inoshanda elastomeric zvinhu zvine huwandu hwakawanda hwekushandisa. Kutenda kune yakasarudzika zvimiro, senge yakakwira elasticity, yakaderera density uye yakanakisa processability, POE inoratidza hukuru hwekugona munzvimbo dzinoverengeka. Ingave muindasitiri yemotokari, indasitiri yekurongedza, kana kugadzira tambo, POE inovhura mikana mitsva mune zvekushandisa sainzi uye engineering.
Ndinovimba, kuburikidza nechinyorwa ichi, vaverengi vanowana kunzwisisa kwakajeka kwekuti POE chii uye nei ichitora nzvimbo yakakosha muindasitiri yemakemikari.
