Epdm (ethylene Procylene Diene Monomer) Rubber
Epdm Rubberis a copolymer ye ethylene, procylene uye chidiki chidiki cheyechitatu monomer isiri-yakavhenganiswa diene. Izita repasi rese ndeiyi: Etheiene Propyene Diene Diene MetHyene, kana EPDM yePfupi. Epdm Rubber ine yakanaka kwazvoUV kuramba, kupokana kwemamiriro ekunze, kupisa kwekutanga kupokana, kupisa kwakadzika kupesana, kupokana kwemakemikari, kupokana kwemakemikari, kupokana kwemvura, kusimbisa kwemagetsi uye nekuwedzera kwemagetsi, uye zvimwe zvimiro zvemuviri uye zvemakaniki. Izvi zvakanakira hazvigone kutsiviwa nezvimwe zvinhu zvakawanda.
1. Kupokana Kwemamiriro ekunzeIko kugona kwekuramba kwakanyanya kutonhora, kupisa, kuoma, kunyorova kweguva yakareba, uye ine hupenyu hwakanakisa hwekurwisa chando nemvura, izvo zvinokwanisa kuwedzera hupenyu hwebasa remasuo, windows uye madziro emadziro.
2. Kupisa kukwira kurwisa kunoreva kuti zvine simba rakasimba kune kupisa kwemhepo kuchembera. Inogona kushandiswa pa -40 ~ 120 k kwenguva yakareba. Inogona zvakare kuchengetedza hunhu hunoshanda kwenguva yakareba pa140 ~ 150 ℃. Inogona kutsungirira kupisa kwakanyanya kwe230 ~ 260 ℃ munguva pfupi pfupi. Inogona kutamba chinzvimbo mukuvaka kwemaguta kubhowa. Kunonoka kuita; yakabatanidzwa nekushandiswa kweiyo yakakosha formula,Epdm Rubberine chinonzwa chakafanana kubva -50 ° C kusvika 15 ° C. Iyi yekugadzira saiti yekuisa yakagadzira yakanyanya-kugona mhedzisiro.
3. NekutiEpdmine yakanakisa kupesana, inozivikanwa se "kupenga-kusununguka rabara". Izvo zvinonyanya kushandiswa muzvivakwa zvakasiyana zveguta zvine mwero wakasiyana emhepo uye hwakazara zvachose nemhepo. Izvo zvicharatidzawo hukuru hwayo hwechigadzirwa.
4. Kudzivirira kuIltraviolet radiation inopa kuchengetedza kwezvakatipoteredza kune vashandisi zvivakwa zvakakwirira-zvakakwira; Zvinogona kutsungirira 60 kusvika ku15kv voltage, uye ine yakanakisa corona kupesana, magetsi ekupenga kupesana, uye arc kuramba. Yakadzika tembiricha yekuwedzera, tembiricha apo huwandu hwesimba rinosvika 100mpa iri -58 ℃.
5. Nekuda kweiyo yakanakisa nzira dzakasarudzika dzemakirini, mota, zvikepe, zvakakwirira-madhiri, zvikepe zveVidhiri uye zvimwe zvikwangwani zvemvura uye zvimwe zvimedu zvemvura uye zvimwe zveindasitiri uye zvekurima kuiswa zvikamu.
