Sponge Profile uye Foamed Parts: The Ultimate Solution ine Anti-ruzha, Weather-resistant EPR Raw Rubber
Sumo
Kubva pamaonero enyanzvi dzerabha, anti-ruzha, inodzivirira mamiriro ekunze ethylene propylene rabha—EPR mbishi rabha—inopa mhinduro yakanaka kwazvo yezvisimbiso zvechisimbiso, kunyanya mumativi ane foam propylene rubber. Rabha iyi ine yakakwira Mooney viscosity, yakakwira ENB yemukati, kukurumidza kurapa kukurumidza, uye yakakwira michina zvivakwa zvinovimbisa kushanda kwenguva refu uye kusimba.
High Mooney Viscosity
EPR mbishi rabha inoratidza yakakwira Mooney viscosity, iyo inova nechokwadi chekuita zvakanaka uye kuumba zvivakwa. Iyi viscosity inobvumira kuve nyore kubata uye kunyengedza panguva yekugadzira, kuve nechokwadi chekuberekana uye kuenderana mukugadzirwa. Iyo yakakwira viscosity inobatsirawo pakuvandudzwa kwekuisa chisimbiso, ichiita kuti ive yakakodzera kune akasiyana chisimbiso maapplication.
Yakakwira ENB Zvemukati
EPR raw rabha ine huwandu hwakanyanya hweENB (ethylene-propylene-butylene), iyo inobatsira kune yayo yakasarudzika. ENB inowedzera kuchinjika uye kuomarara kune rabha, ichivandudza ma mechanika ayo. Iyo yakakwira ENB yemukati inoitawo kuti rabha rirambe richimira kumamiriro ekunze, kuve nechokwadi chekugara kwenguva refu mumashandisirwo ekunze.
Kurumidza Kurapa Yekumhanyisa
EPR mbishi rabha inoratidza kukurumidza kurapa kukurumidza, zvinoreva kuti inogona kugadziriswa nekukurumidza pasina kupira mhando. Iko kukurumidza kuporesa kumhanya kunoita kuti vagadziri vawane nguva pfupi yekutenderera, kuvandudza kugadzirwa, uye kuderedza mitengo yekugadzira. Pamusoro pezvo, kukurumidza kurapwa kwerabha kunovimbisa yakasimba uye yakavimbika chisimbiso pakuiswa.
Yakakwira Mechanical Properties
EPR mbishi rabha inoratidza yakakwira michina zvivakwa, zvinosanganisira kusimba kwesimba, modulus, uye kuoma. Izvi zvivakwa zvinovimbisa kuti rabha rakakodzera kune kwakasiyana-siyana yekuisa chisimbiso uko kune yakasimba uye yakasimba zvisimbiso zvinodiwa. Iyo mechanic zvimiro zveEPR mbishi rabha inoita kuti ive sarudzo yakanakisa yekuisa chisimbiso muchimiro chesiponji uye zvikamu zvine furo.
Muchidimbu
EPR raw raw's high Mooney viscosity, yakakwira ENB zvemukati, kukurumidza kurapa kukurumidza, uye yakakwirira michina zvivakwa zvinoita kuti ive chinhu chakanakira chisimbiso maapplication musponji mbiri uye zvikamu zvine furo. Iyo rabha yekuisa chisimbiso yakanakisa uye kuramba kwemamiriro ekunze kunogonesa kuita kwenguva refu uye kusimba mumhando dzakasiyana dzekuisa chisimbiso. Iko kukurumidza kuporesa kumhanya kunoita kuti vagadziri vakwanise kuwana nguva pfupi yekutenderera uye kugadzirisa kugadzirwa, kuderedza mutengo wekugadzira uchichengetedza mhando. Iyo mechanical properties inovimbisa kuti rubber inokodzera zvakasiyana-siyana zvekuisa chisimbiso apo zvisimbiso zvakasimba uye zvakasimba zvinodikanwa. Chiponji chimiro uye zvikamu zvine furo neEPR mbishi rabha zvinopa mhinduro yekupedzisira yekuisa chisimbiso maapplication anoda anti-ruzha uye kuramba mamiriro ekunze.
