Ibyuma byawe byo mu bwoko bwa valve biri kwangirika bitewe n'ubushyuhe n'izuba byo mu turere dushyuha. Ibi bituma habaho amazi ahenze, kudakora neza kwa sisitemu, ndetse n'abakiriya batishimye bashidikanya ku bwiza bw'ibicuruzwa byawe n'izina ryawe.

Ku turere dushyuha, EPDM ni nziza cyane ku mazi yose akoreshwa ahura n'izuba n'ikirere bitewe nuko arwanya cyane imirasire ya UV na ozone. Koresha NBR gusa mu mazutu arimo amavuta, aho irinzwe n'izuba.

Narimo mvugana na mugenzi wanjye Budi wo muri Indoneziya ku kibazo gikomeje guhura nacyo umwe mu bakiriya be. Bari bashinzwe ubuhinzi bunini bw’amafi aho amavali yacu amagana yashyizwe hanze. Nyuma y’amezi atandatu gusa, menshi yatangiye kuva. Amavali yari meza, ariko amabati asanzwe ya NBR imbere yari arimo kwangirika no kwangirika. Iki ni ikibazo gisanzwe mu turere dushyuha. Uruvange rw’izuba ryinshi, ubushyuhe bwinshi, n’ubushuhe byangizaga rabha. Twabafashije guhindura amavali hamwe n’amavali yacu.Ibyuma bya EPDM, kandi ikibazo cyarashize. Ubu bunararibonye bwerekana neza impamvu guhitamo ibikoresho ari ingenzi cyane mu duce dushyuha.

Ni ikihe cyiza mu turere dushyuha, NBR cyangwa EPDM?

Imisego ya NBR irahendutse, ibi bikaba bisa neza ku giciro. Ariko se ibi bizakurinda ingaruka mbi mu gihe imisego yangiritse vuba bitewe n'izuba ryinshi n'ubushyuhe bwinshi bwo mu turere dushyuha?

Ku bijyanye n'amazi yo mu turere dushyuha, EPDM ni nziza cyane. Imiterere yayo y’ibinyabutabire yubatswe kugira ngo irwanye imirasire y’izuba, ozone n’ubushyuhe. Kuba NBR idahangana n’ikirere neza bituma iba amahitamo akomeye yo gukoreshwa hanze mu gace gashyuha.

Ibi si ikibazo cy'ibitekerezo, ni ikibazo cya chimie. EPDM ifite icyo bitaurutirigongo rwa polymer yuzuye. Iyi nyubako ihamye irarwanya ibitero by’imirasire ya UV na ozone, ibintu bibiri biboneka mu kirere cy’izuba kandi gishyuha. Ku rundi ruhande, NBR ifite umugongo udafite amazi menshi ufite imigozi ibiri. Iyi migozi ibiri ni ingingo zoroheje zishobora gucikamo imiyoboro ya UV, bigatuma ibikoresho bicika intege kandi bigacika. Ahantu nka Indoneziya cyangwa Vietnam, sisitemu yo kuhira cyangwa yo gutunganya amazi hanze ihura n’izuba rihoraho. Umugozi wa NBR ushobora kwangirika mu gihe kitarenze umwaka. Umugozi wa EPDM mu gace kamwe ushobora kumara imyaka myinshi. Igiciro cya mbere cya EPDM kiri hejuru gato ni igiciro gito cyo kwishyura kugira ngo wirinde kwangirika kw’igihe kirekire no kwirinda kwangirika kwa sisitemu. Isesengura ry’ikiguzi n’inyungu rishyigikira cyane EPDM ku ikoreshwa ryose ryo hanze.

Ni izihe mbogamizi za EPDM rubber?

EPDM isa neza cyane ku miyoboro y'amazi yo hanze. Ariko se bigenda bite iyo amazi arimo amavuta cyangwa imiti ikomoka kuri hydrocarbon? Gukoresha nabi bishobora gutuma agafunga kananirwa burundu.

Ingorane nyamukuru ya EPDM ni uko idakomera cyane ku bintu bikomoka kuri peteroli nk'amavuta, amavuta, n'ibindi bintu byinshi bishongesha. Gukora kuri ibi bintu bizatuma EPDM seal ibyimba, yorohe, kandi igatakaza ubushobozi bwo kuyifunga.

Itegeko muri chimie ni "nk'ibishonga nk'ibishongesha." EPDM ni ibikoresho bitari polari, ndetse n'amavuta ya hydrocarbon nayo ni uko. Iyo bihuye, EPDM ifata amavuta, bigatuma abyimba nk'ikirungo. Uku kubyimba guca intege cyane ibikoresho kandi bigasenya ubushobozi bwabyo bwo gufata agapfukamunwa mu gihe cy'umuvuduko. Ibi bituma bidakwiye gukoreshwa mu miyoboro ya lisansi, sisitemu za hydraulic, cyangwa imikorere myinshi ya shimi mu nganda. Indi mbogamizi ni ikiguzi. EPDM ni polymer igezweho, bityo ikiguzi cyayo cyo kuyikora kiri hejuru kurusha NBR. Niyo mpamvu ikunze kubonwa nk'uburyo bwiza. Ariko, ni ngombwa kureba iki kiguzi mu rwego rwo kuyikoresha. Kugira ngo ubone akazi gakwiye (amazi, ikirere, ubushyuhe), igiciro cy'ibanze kiri hejuru kiguhemba imyaka myinshi ya serivisi idafite ibibazo, bigatuma ikiguzi cyayo cyose cyo kuyitunga kiri hasi cyane.

Ni izihe mbogamizi nyamukuru za NBR?

NBR ni yo ikoreshwa mu buryo buhendutse mu bikorwa byinshi. Ariko ubushobozi bwayo bwo guhangana n'ikirere bushobora gutuma icikagurika kandi ikananirwa, ibyo bikaba ari ikibazo gikomeye mu bidukikije byo hanze.

Ingorane ikomeye ya NBR ni ubudahangarwa bwayo bukomeye ku zuba rya UV (UV), ozone, n'imihindagurikire y'ikirere muri rusange. Ibi bituma ikomera kandi icika intege. Ifite kandi igipimo cy'ubushyuhe gito cyane ugereranyije na EPDM, bigatuma ishaza vuba mu bihe bishyushye.

Ku isoko nka Budi's muri Indoneziya, iki ni cyo kintu cy'ingenzi cyane cyo gusobanukirwa. Guhuza imirasire y'izuba ikabije umwaka wose n'ubushyuhe bwinshi bwo mu kirere ni byo bintu bibi cyane kuri NBR. Imirasire ya UV yibasira imiyoboro ya polymer mu buryo butaziguye, mu gihe ubushyuhe bwihutisha iyi gahunda yo gusaza. Ibi bituma ibikoresho bitakaza ubushobozi bwabyo bwo kwiyoroshya, ari na yo nshingano yabyo y'ibanze. Ifu ipfutse ntishobora gukanda kugira ngo ihagarike amazi; iracika gusa iyo umuntu asunitswe n'umuvuduko. Niyo mpamvu tubona byinshi byangiritse ku miyoboro isanzwe ya NBR mu buhinzi bushyuha no mu miyoboro yo hanze. Iyi ntege nke ireba kandi ozone. Ozone ikorwa mu buryo busanzwe n'izuba kandi ikoreshwa muri sisitemu zimwe na zimwe zigezweho zo gusukura amazi. Ndetse n'ingano nto ya ozone izagabanuka vuba NBR. Muri make, gukoresha NBR mu bikorwa byose byo hanze mu turere dushyuha ni ukwirengagiza ko ibicuruzwa byawe byizewe kandi ko izina ryawe ari ryo ry'ukuri.

Ese koko umupira wa NBR urwanya ubushyuhe mu turere dushyuha?

Urabona igipimo cy'ubushyuhe kuri rubber ya NBR ku rupapuro rw'igenzura. Ariko se icyo gipimo ni icyo kwizerwa mu karere gashyuha mu buryo busanzwe aho ubushyuhe bwo mu kirere busanzwe buri hejuru cyane?

NBR irinda ubushyuhe buri ku rugero runaka, ubusanzwe igera kuri 120°C (248°F). Ariko, iyi ntarengwa igabanuka iyo ikomeje gushyuha. Uruvange rw'ubushyuhe bwinshi n'ubushyuhe bukoreshwa mu turere dushyuha bishobora gutuma NBR igera ku iherezo ryayo, bigatera kwangirika imburagihe.

Urupapuro rw'ibipimo rushobora kuyobya iyo rudasomwa neza. Iyo ngero ya 120°C akenshi iba iy'ubushyuhe budahindagurika, ntabwo ari ubushyuhe buhoraho. Mu karere gashyuha cyane, ubushyuhe bwo mu kirere bushobora kuba bumaze kuba 35°C. Agakoresho kari ku zuba ryinshi hejuru y'inzu gashobora kugera ku bushyuhe bwo hejuru bwa 70°C cyangwa burenze, ndetse na mbere y'uko amazi ashyushye anyuramo. Uyu mutwaro uhoraho w'ubushyuhe ushyira ibikoresho bya NBR mu muvuduko uhoraho. EPDM, ifite ingano isanzwe ya 150°C, ifite urwego runini rw'umutekano. Ishobora kwihanganira umuvuduko woroshye w'ubushyuhe bwinshi n'amazi ashyushye adahinduka. Iyi ni nziza cyane.guhagarara neza k'ubushyuheIyi ni indi mpamvu ikomeye ituma dusaba cyane EPDM kugira ngo ikore neza igihe kirekire mu bihe bishyushye.

Umwanzuro

Ku birebana n'amazi yo mu turere dushyuha, EPDM ifite ubushobozi bwo kwirinda imirasire ya UV n'ubushyuhe ni ngombwa. Irinde imirasire ya UV gusa ku bikoresho birinzwe byo mu nzu, bikoresha amavuta. Guhitamo neza bitanga umusaruro mwiza kandi w'igihe kirekire.
