Vharuvhu yeBhabhata Inogarwa neRabha ine EPDM Sealing: Pfupiso Yakakwana

**Mavharuvhu eshavishavi akagarwa nerabha ane zvisimbiso zveEPDM: ongororo yakazara**

Mavharuvhu eshavishavizvinhu zvakakosha mumashandisirwo akasiyana-siyana emaindasitiri, zvichipa kudzora kuyerera kwemvura mumapaipi zvinobudirira. Pakati pemhando dzakasiyana dzemavharuvhu eshavishavi, mavharuvhu eshavishavi akagadzikwa nerabha anoonekwa zvakanyanya nekuda kwekugadzirwa kwawo kwakasiyana uye mashandiro awo. Chimwe chezvinhu zvakakosha muchikamu ichi kushandiswa kwezvisimbiso zveEPDM (ethylene propylene diene monomer), izvo zvinovandudza mashandiro uye kugara kwenguva refu kwevharuvhu.

Zvisimbiso zveEPDM zvinozivikanwa nekusapisa zvakanyanya, ozone uye mamiriro ekunze, zvichiita kuti zvive zvakanaka pakushandiswa zvinoda kuvharwa kwakavimbika mumamiriro ezvinhu akaoma. Kana zvakabatanidzwa mumavharuvhu emabhatani akaiswa rabha, zvisimbiso zveEPDM zvinovhara zvakasimba, zvichideredza njodzi yekudonha kwemvura uye zvinovimbisa kudzora kuyerera kwemvura zvakanaka. Izvi zvakakosha zvikuru mumaindasitiri akadai sekurapa mvura, kugadzirisa makemikari uye masisitimu eHVAC, uko kuchengetedza kusimba kwesisitimu kwakakosha.

Mavharuvhu eshavishavi agere murabhaZvisimbiso zveEPDM zvine mabhenefiti akati wandei. Chekutanga, EPDM inogona kutsungirira tembiricha yakakura, kazhinji -40°C kusvika 120°C, zvichiita kuti ikwanise kushandiswa pakupisa nekutonhora. Chechipiri, kuchinjika kwechigaro cherabha kunoita kuti chishande zvakanaka, zvichideredza simba rinodiwa kuti vharuvhu ivhurwe nekuvhara. Ichi chinhu hachingobatsiri chete mushandisi, asiwo chinowedzera hupenyu hwevharuvhu.

Pamusoro pezvo, dhizaini yevharuvhu remapuruguru, pamwe chete nechisimbiso charo chakasimba cheEPDM, zvinoita kuti zvive nyore kuisa nekugadzirisa. Vashandisi vanogona kutsiva chisimbiso nekukurumidza pasina chikonzero chezvishandiso zvakakosha, zvichiita kuti nguva yekushanda ive shoma.

Mukupedzisa, mavharuvhu emabhatafura ane rabha ane zvisimbiso zveEPDM anomiririra hunyanzvi hukuru mu tekinoroji yekudzora kuyerera kwemvura. Kugara kwawo kwenguva refu, kuramba zvinhu zvakatikomberedza uye nyore kugadzirisa kunoita kuti ave sarudzo yepamusoro kune akasiyana mashandisirwo emaindasitiri. Sezvo indasitiri ichiramba ichichinja, kudiwa kwemhinduro dzemavharuvhu dzakavimbika uye dzinoshanda pasina mubvunzo kuchakura, nokudaro zvichibatanidza basa remavharuvhu emabhatafura ane EPDM muinjiniya yemazuva ano.
