EPDM gasketi: ikoreshwa rirambye ryinganda? 

Urumva EPDM gasketi hamwe no kuramba mumyuka imwe, kandi reaction ihita mumuzingi imwe nimwe yo gusebanya. Ibitekerezo bigenda: ni reberi yubukorikori, ikomoka kuri peteroli, none birashoboka gute? Nubuso-urwego rufata, kandi rukabura amateka yubuzima bukora. Tumaze kwerekana no kubona kashe zananiranye kandi zigatsinda mumurima, impaka zirambye ntabwo zerekeye inkomoko yibikoresho byonyine-ni ukuramba, kubika ingufu, no kugabanya inzitizi zose zisimburwa. Niba gaze imara imyaka 15 aho kuba 5, ibyo ni ukugabanuka gukabije kwimyanda, amasaha yo hasi, hamwe ningufu zikomoka mubikorwa no kuyishyiraho. Aho niho ikiganiro nyacyo gitangirira.

Ikigereranyo cyo Kuramba: Kurenza Ibihe Kurwanya Ikirere

Buriwese azi amayeri yishyaka rya EPDM: kurwanya bidasanzwe ozone, UV, nikirere. Icyo ni igitabo. Ariko intsinzi irambye ituruka kubyo iyo myigaragambyo ituma mubikorwa nyabyo, biteye ubwoba. Ndavuga kubyerekeye gusiganwa ku magare mu miyoboro yo gushyushya uturere, cyangwa guhora hamwe mu gukonjesha umunara. Mu mushinga umwe wa retrofit wo mu ruganda rwagati rwagati rwifashisha imiyoboro yingirakamaro, twahinduye uruvange rwa neoprene ishaje na kashe ya nitrile kuri EPDM. Ikidodo cyabanjirije cyateshaga agaciro buri myaka 3-4, bigatuma habaho kumeneka no guhora kubungabunga. EPDM dushyiramo? Turimo kubakurikirana, kandi ntibagaragaza ko nta compression ihambaye yashizweho cyangwa guturika hejuru nyuma yimyaka 8. Nibyo bibiri byuzuye byo kubungabunga birinze. Imyanda iva muri ayo gaseke ishaje - akenshi yanduye kandi idashobora gukoreshwa - yahagaritse kubyara.

Kuramba bisobanura muburyo bwo kubungabunga umutungo. Ntabwo uhora ukoresha ibikoresho bishya bibisi, ingufu zumusaruro, cyangwa lisansi ya logistique kugirango ibice bisimburwe. Ndibuka impaka numuyobozi ushinzwe amasoko yibanze gusa kubiciro bya buri gice. Ihitamo rya EPDM ryari 30% bihenze imbere. Tugomba kubaka urubanza rwerekana igiciro cyose cya nyirubwite, harimo n'umurimo wo guhagarika kabiri byongeye ndetse no gutakaza amazi ava. Iyo byakozwe nka a gukoresha inganda zirambye, icyerekezo kirekire cyatsinze. Nibikorwa bifatika, ntabwo ari filozofiya, irambye.

Hano hari caveat, birumvikana. Uku kuramba gushingiye kumahitamo meza. EPDM irazwi cyane hamwe namavuta menshi ashingiye kuri peteroli. Nabonye binaniwe kuburyo budasanzwe kandi byihuse mumurongo wohereza amavuta aho umuntu yakekaga ko reberi ari rubber. Ibyo gutsindwa ntibyari ikimenyetso kirwanya EPDM irambye; cyari ikimenyetso cyo kurwanya imikorere mibi yubuhanga. Porogaramu irambye ni porogaramu ikwiye.

Gukoresha Ingufu: Kwihuza

Iyi ni inguni itagaragara ariko ikomeye. Muri HVAC hamwe na sisitemu yo kubika inganda, gasike ni igice cy ibahasha yumuriro. Ikidodo cyangiritse kiganisha ku kiraro gishyuha no gutakaza ingufu. Imiterere ya polymer ihamye ya EPDM hamwe nubushyuhe buke bwumuriro bituma ihitamo neza mugukingira ikoti yikoti, ikibaho cyo kumashanyarazi, cyangwa flanges. Twakoze kuri kaminuza yo kuzamura ingufu za kaminuza aho birukaga kugabanya 10% igihombo cyo gushyushya ibihingwa. Igice kinini cyubugenzuzi bwerekanaga kashe yangiritse ku byambu amagana. Kugaragaza igifunga-selile EPDM ifuro gasike hano yakoze ibintu bibiri: yashyizeho inzitizi yumwuka wizewe, kandi ibikoresho byihariye byo kubika byongeweho R-agaciro. Kwishura byabazwe mu mezi, ntabwo ari imyaka, gusa ku mbaraga zabitswe. Ibyo nibikorwa biramba hamwe na metero yubukungu itaziguye.

Ntabwo ari ugukomeza ubushyuhe gusa. Muri firigo no kubika imbeho, gukumira umwuka ushushe, utose ni byose. Ibyabaye byinjira bihatira sisitemu gukora cyane, ikoresha amashanyarazi menshi, kandi irashobora gutuma habaho urubura. Igikoresho cyoroshye, ubushyuhe buke bworoshye EPDM gaseke kumuryango ni bisanzwe kubwimpamvu. Nagereranije kwishyiriraho nkoresheje kashe rusange ya PVC na EPDM ikwiye. Inzugi za EPDM zagumanye kashe ihamye igihe kirekire, hamwe no guhindura bike bikenewe. Ingufu zingufu zerekanaga itandukaniro rigaragara muri compressor cycle inshuro. Ubu ni ubwoko bwa granular, bushobora gupimwa busobanura kubaho-kwisi kuramba.

Inzitizi zuzenguruka hamwe nukuri-Impera yubuzima

Reka tuvugishe ukuri: inkuru yanyuma yubuzima kuri gaseke ya EPDM ntabwo ari umuzenguruko. Nibikoresho bya termoset. Ntushobora kubashonga no kubavugurura nka thermoplastique. Mu kuvanaho inganda nyinshi, zuzuye imyanda cyangwa zirashya kugirango ingufu zisubirwe. Nibintu binini bihabanye nibisabwa biramba, kandi biremewe. Inganda zasubije ntabwo ziri mu gutunganya gaze yakoreshejwe, ahubwo ni mugushushanya kuramba bikabije, nkuko byaganiriweho, no mugushakisha ibikoreshwa mu gutunganya ibicuruzwa bishya bya EPDM.

Bamwe mubaterankunga ubu batanga amanota ya EPDM hamwe nibikorwa byingenzi nyuma yinganda zikoreshwa muri EPDM. Ntabwo biva mubikapu bishaje, mubisanzwe, ahubwo biva kumyanda yimyanda mugihe cyo gukora ikirere cyimodoka cyangwa ibisenge. Ibi bifunga uruziga muri ecosystem yinganda. Twagerageje bimwe muri ibyo bikoresho bivuye kubitanga mu ntara ya Hebei, ihuriro rikuru ry’inganda, kandi guhagarika ibikorwa birashobora kuba bike kubintu byinshi bifunga kashe. Ni intambwe. Kuri sosiyete nka Hamagara zitai yihuta ukora co., Ltd., iherereye hagati mu Bushinwa hashingiwe ku bicuruzwa bisanzwe by’ibicuruzwa muri Yongnian, kugera ku migezi nk'iyi n'ibikoresho byo kubishyira mu nteko zihuta kandi zifunga ni inyungu ifatika. Umwanya wabo uherekeza imiyoboro minini yo gutwara abantu nka Gari ya moshi ya Beijing-Guangzhou hamwe n’umuhanda w’igihugu 107 bivuze ko bashobora kuvana neza ibyo bikoresho no gukwirakwiza ibicuruzwa byarangiye, birashoboka ko bishobora kugabanya ikirenge cya karubone cy’ibicuruzwa ubwabyo. Urashobora kubona uburyo bwabo mubikorwa bihuriweho kuri https://www.zitaifacens.com.

Iyindi nzira yanyuma-yubuzima ni guhanga kumanuka. Nabonye kashe ya tank ya EPDM ishaje, imaze gusukurwa, gutemwa no gukoreshwa nka padi, matel anti-vibration, cyangwa no mumikino yo gukiniraho. Ntabwo ari agaciro gakomeye ko gutunganya, ariko ni ukuvana mumyanda. Intego igomba kuba ugukora intera isimburwa igihe kirekire kuburyo iherezo ryubuzima riba ikibazo cya kure, kidakunze kubaho.

Ikiburanwa: Gutunganya Amazi na Imiti ikaze

Ibihingwa bitunganya amazi n’amazi nubutaka bushimishije. Hano, kuramba bisobanura gukumira umwanda no kwemeza imyaka mirongo ya serivisi yizewe. EPDM ni inyenyeri yo guhuza amazi meza (guhura na NSF / ANSI 61) no gukemura ibintu byinshi bya acide ya acide, alkalis, hamwe n’imiti ya polar iboneka muburyo bwo kuvura. Muri tanki ya kabiri isobanura retrofit, twakoresheje gaze ya EPDM yuzuye ya peroxide ikize kuri feri nini ya diameter. Ibidukikije byari ubuhehere buri gihe, gukura rimwe na rimwe kwa algal, hamwe n’imiti yoroheje yatewe no kuvura.

Ubundi buryo bwatekerejweho ni gaseke ya PTFE. Mugihe hashyizwemo imiti myinshi, nibikoresho byinshi cyane bitanga ingufu kugirango bitange kandi bikunda gutemba bikonje (creep) munsi yumutwaro wa bolt, bisaba kongera gutwikwa. Ihitamo rya EPDM ryatanze kashe yizewe hamwe nibintu byiza byo kugarura ibintu, byashizweho rimwe ukibagirwa. Imyaka itanu irashize, nta kumeneka, nta kubungabunga. Ibarura rirambye hano ryagaragaye mu kwirinda ingaruka ziterwa n’ibidukikije, ingufu zikubiyemo PTFE, n’umurimo wo kubungabunga. Uwiteka EPDM yari ihitamo rirambye ryuzuye, ndetse kuruhande rwibikoresho bihebuje nka PTFE.

Uburyo bwo kunanirwa kwitondera: mubuvuzi bwibanze cyangwa gufata amashanyarazi hamwe namavuta menshi hamwe na hydrocarubone, EPDM byaba ari amahitamo mabi. Aho niho umwihariko ari umwami. Kuramba ntabwo ari ikintu kimwe-gihuza-badge yose.

Kugaragaza Kuramba: Ibya Sekibi murambuye

None, nigute ushobora guhitamo muburyo burambye? Itangirana nurupapuro rwabigenewe. Ntukandike gusa igipapuro cya EPDM. Ibyo ni ubunebwe. Kugaragaza ibice: saba uburyo bwo guhunika buke (ASTM D395), umuti wa peroxide kugirango urwanye ubushyuhe bwigihe kirekire, hamwe nuburemere bwihariye niba ukeneye kashe yuzuye, idashobora kwihanganira. Baza ibyerekeranye nibisubirwamo. Uru rwego rurambuye rwerekana ababikora ko imikorere nibikorwa byubuzima.

Ibi nabyize binyuze kunanirwa byoroheje. Twategetse EPDM isanzwe kumurongo wamazi ashyushye. Yakoze neza kubushyuhe, ariko uruganda rwari rworoshye cyane. Mu myaka ibiri, yahuye nogusohora gukomeye kumpande zingana, biganisha kumeneka gahoro. Ibicuruzwa biramba biramba byarananiranye kuko ntitwagaragaje guhangayikishwa nubukanishi. Twabisimbuje bikomeye, 80-durometero, EPDM ikomezwa. Kuva icyo gihe. Isomo: kuramba bisaba ubuhanga bwuzuye. Ntabwo ari uburyo bwo kwamamaza; ni ibisubizo byubumenyi bukwiye nubushakashatsi.

Hanyuma, gufatanya nabahimbyi babyumva. Isosiyete yinjiye mu musaruro nkakarere ka Yongnian, nka Handan Zitai Fastener, akenshi ifite uburambe bufatika bwibikorwa murwego. Babona kunanirwa kugaruka kandi barashobora gutanga inama kubijyanye no guhitamo ibice. Ubuhanga bwabo muri sisitemu yihuta kandi bivuze ko basobanukiwe imikoranire ikomeye hagati ya gaze, hejuru ya flange, hamwe nuburyo bwo guhinduranya - byose ni ngombwa kugirango umuntu agere ku buzima bwasezeranijwe.

Kurangiza Ibitekerezo: Icyemezo gifatika

Igipimo cya EPDM nikintu kirambye cyinganda? Igisubizo ni yego. Kuramba kwayo ntabwo kurangwa ariko kugerwaho. Byagerwaho binyuze mugukoresha igihe kirekire cyamamare kugirango habeho ubundi buryo, bityo bigabanye imyanda n'ingaruka zingufu zigihe. Yongerewe imbaraga ninshingano zayo mugutezimbere ingufu muri sisitemu yubushyuhe. Umwirondoro wacyo watezimbere mugushyiramo ibintu bitunganijwe neza hamwe nibikoresho byiza biva mubakora ibicuruzwa byakorewe hamwe.

Iterabwoba rikomeye kumyizerere irambye ni ugukoresha nabi. Byakoreshejwe neza, muburyo bwiza bwimiti nubushyuhe, kashe ya EPDM nimwe muburyo bwizewe kandi burambye burahari. Kuramba ni ishingiro ryimpaka zidukikije. Ntabwo bizakemura ikibazo cya thermoset recycling puzzle, ariko kumara imyaka mirongo, itera icyo kibazo mugihe kizaza mugihe gitanga imikorere mikorere uyumunsi. Mukurangiza, gasike irambye niyo utagomba gusimbuza.
