Ibikoresho bya EPDM ni iki? –Mwisesengura ryimbitse kubiranga no gukoresha reberi ya EPDM
EPDM (Ethylene-propylene-diene monomer) ni reberi yubukorikori hamwe nikirere cyiza, ozone n’imiti irwanya imiti, kandi ikoreshwa cyane mu binyabiziga, ubwubatsi, ibikoresho bya elegitoroniki n’izindi nganda. Mbere yo gusobanukirwa icyo EPDM ikozwe, birakenewe gusobanukirwa imiterere yihariye ya molekile nuburyo bwo gukora kugirango twumve neza imiterere n'imikoreshereze.
1. Ibigize imiti nuburyo bwa molekuline ya EPDM
EPDM reberi ibona izina ryayo mubice byingenzi: Ethylene, propylene na diene monomers. Aba monomers bakora iminyururu ya polymer yoroheje binyuze muri copolymerisation reaction. Ethylene na propylene bitanga ubushyuhe buhebuje no kurwanya okiside, mugihe monomer ya diene yemerera EPDM guhuzwa na volcanisation cyangwa peroxide, bikarushaho kongera imbaraga nigihe kirekire cyibikoresho.
2. Ibikorwa byingenzi biranga EPDM
Bitewe n’imiterere yihariye y’imiti, EPDM ifite ibintu byinshi byiza cyane bituma igaragara neza mu murima mugari.EPDM ifite ikirere cyiza kandi irwanya UV, bivuze ko ishobora guhura n’umucyo wizuba igihe kirekire nta kwangirika.EPDM nayo ifite imbaraga zo guhangana na ozone, ituma ikomeza gukora neza mubihe bidukikije bidakabije.
Ikindi kintu cyingenzi kiranga imiti yacyo, cyane cyane kuri acide, alkalis hamwe nudukoko twinshi twa polar. Kubwibyo, EPDM ikoreshwa kenshi mubihe bisaba guhura nigihe kirekire n’imiti.EPDM ifite ubushyuhe bwinshi bwimikorere, kandi mubisanzwe irashobora gukora mubisanzwe hagati ya -40 ° C na 150 ° C, ibyo bigatuma ikoreshwa cyane mubikorwa byinganda zitwara ibinyabiziga, nka kashe ya idirishya, imashini ya radiator, nibindi.
3. Porogaramu ya EPDM mu nganda zitandukanye
Ikoreshwa ryinshi rya EPDM ryitirirwa guhindagurika hamwe nibintu byiza bifatika. Mu nganda zitwara ibinyabiziga, EPDM isanzwe ikoreshwa mugukora kashe, kashe yumuryango, ibyuma byogeza umuyaga hamwe namashanyarazi. Bitewe nubushyuhe bwabo no gusaza, ibyo bice bigumana ubuhanga bwimikorere nigihe kinini, bizamura ubuzima bwikinyabiziga.
Mu nganda zubaka, EPDM ikoreshwa cyane mugukingira amazi hejuru yinzu, kashe yumuryango nidirishya hamwe nibindi bikorwa bisaba kwirinda amazi no kurwanya UV. Kurwanya ikirere cyiza no guhinduka bituma imiterere ihagaze neza hamwe no gufunga imikorere yinyubako.EPDM ikoreshwa kandi mubikoresho byo gutema insinga ninsinga, bitanga uburyo bwiza bwo gukumira amashanyarazi no kurwanya imiti.
4. EPDM kurengera ibidukikije niterambere rirambye
Muri iki gihe murwego rwo kurushaho kurengera ibidukikije bikenewe, EPDM nayo ihangayikishijwe no kurengera ibidukikije ndetse n’iterambere rirambye. EPDM ni ibikoresho bisubirwamo, uburyo bwo kubyaza umusaruro imyuka n’imyanda yangiza, bijyanye n’umuryango w'iki gihe ukeneye kurengera ibidukikije. Binyuze mu kunoza imikorere y’umusaruro, ingufu n’umutungo wa EPDM nabyo bigenda bigabanuka buhoro buhoro, bigira uruhare mu iterambere rirambye ry’inganda.
Umwanzuro
Ibikoresho bya EPDM ni iki? Nibikoresho bya sintetike ya reberi hamwe nibikorwa byiza kandi bigari byinshi. Hamwe n’imihindagurikire y’ikirere, kurwanya imiti n’ibidukikije byangiza ibidukikije, bigira uruhare runini mu nganda zitandukanye. Haba mu nganda zitwara ibinyabiziga, inganda zubaka, cyangwa amashanyarazi na elegitoroniki, EPDM yahindutse ibikoresho byingirakamaro kubera imikorere yayo myiza.
