Urabona iki kibazo kigaragaye muri spes cyangwa kiva kumukiriya, kandi igitekerezo cyahise ntabwo kijyanye numutungo umwe wibintu-byerekeranye nukuri kwuzuye akajagari kibaho mugihe ushyizeho kashe hagati yidirishya ryimuka n'ikariso yo kwiyuhagiriramo, utegereje ko izamara imyaka myinshi kurwanya ubushyuhe, amazi, hamwe no kwikuramo buri gihe. Ijambo 'grafite' akenshi rijugunywa nkumukungugu wubumaji, bivugwa ko uzamurwa, ariko nibyo? Kuva igihe cyanjye cyo gushiraho no gusimbuza, ibiganiro biramba ntibikunze kuba hafi ya gaze ubwayo. Byerekeranye na sisitemu, ibidukikije, kandi mvugishije ukuri, bimwe bitumvikana muburyo bwo gutanga amasoko.

Isezerano rya Graphite na Kurubuga

Abatanga ibicuruzwa bakunda kugabanya reberi yashizwemo. Ikibanza cyo kugurisha gihora kijyanye no kugabanya ubukana, gufunga neza munsi yo kwikuramo, no kuramba. Kandi mubyukuri, birumvikana. Graphite ni amavuta akomeye. Mubikorwa bigenda neza nkumuryango woguswera aho idirishya cyangwa ikibaho cyanyerera cyangwa pivot, kugabanya ubushyamirane hejuru yikibuye cya reberi bigomba kubuza guturika cyangwa guhinduka hakiri kare. Ariko dore hiccup yambere: ubuziranenge no gukwirakwiza grafite. Nabonye ibyiciro aho grafite isa nkaho isohoka, hasigara ibisigara bitameze neza mubirahure nyuma y amezi make yo kubikoresha, mugihe reberi munsi yacyo isubira muburyo bwayo, igahinduka igicucu cyangwa igacika. Kuramba kuramba? Ntibisanzwe, niba atari bibi. Ntabwo igishushanyo cyatsinzwe; ni uruganda rwahujwe.

Noneho hariho compression yo gushiraho. Iyi nini nini. Igipapuro gisunikwa hagati ya aluminium na panne yikirahure. Imvange nziza ya EPDM cyangwa silicone igomba gusubira inyuma. Wongeyeho igishushanyo cyo kuvanga, kandi kirashobora guhindura ububiko bwa polymer. Ndibuka umushinga hashize imyaka itatu aho twakoresheje premium, grafite-yatewe na EPDM umwirondoro wurukurikirane rwamahoteri yo murwego rwohejuru. Igice cya mbere cyari gitangaje - cyicecekeye, cyoroshye. Ariko nyuma y'amezi 18 yo guhora mukoresha ahantu h'ubushyuhe, hashyushye, gaseke yafashe umwanya uhoraho. Ntibasubiye inyuma. Ikidodo cyahindutse umurongo muto, ushashe, kandi twatangiye kubona guhamagarira amazi. Igishushanyo cyafashaga hejuru kunyerera, ariko se byabangamiye imbaraga zo kwihanganira igitutu gihoraho? Icyo gihe, byasaga naho ari ko bimeze.

Ibi biganisha ku ngingo yagutse: ibanze rya reberi ni umwami. Igishushanyo ninyongera, gihindura. Niba utangiranye na EPDM yo mu rwego rwo hasi cyangwa reberi yongeye gukoreshwa, kongeramo grafite ni nko gushyira umurongo-mfashanyo ku kibazo cyimiterere. Nkunda gushidikanya kubintu bisaba guhamagara gasike ya grafite ntasobanuye neza ibintu fatizo, ubukana bwayo (Shore A), hamwe nubushyuhe bwa serivisi iteganijwe. Ikibazo kiramba gihinduka kuva Grafite ni nziza? Kuri iki gishushanyo kivanze niki, kandi niyihe ntego nyayo?

Ihohoterwa ryibidukikije: Ntabwo ari Amazi gusa

Iyo tuvuze kuri gaseke ya idirishya, 'dushe' nijambo rikora, ubugome. Ntabwo ari igihu cyoroheje. Ni amavuta ashyushye, gusiganwa ku magare kuva mu kirahure gikonje kugeza ku mazi ashyushye, guhura n’imiti biva mu masabune, shampo, na cyane cyane kuvanaho limescale bikabije cyangwa gusukura aside. Igishushanyo mbonera ubwacyo kirashobora kwibasirwa. Mu bice bifite amazi akomeye, imyunyu ngugu (limescale) irashobora guhambira ku buso buto, busize amavuta hejuru ya gaze ya grafite cyane kuruta kuri silicone isanzwe. Ubona iyi gritty, abrasive crust kubaka. Igihe kirenze, burigihe burigihe idirishya ryanyerera, ntabwo ari igishushanyo mbonera cya kirahure; ni ugukurura uduce duto twa abrasive hejuru yubuso bwombi, kwambara gasike kandi birashoboka gushushanya umuyoboro wikirahure.

UV guhura nubundi bwicanyi bwicecekeye, akenshi birengagizwa kubikoresho byo murugo. Ariko amadirishya menshi yubwiherero abona urumuri rwizuba. Ibisanzwe EPDM izwi nabi na UV; iracika kandi itesha agaciro. Silicone ikora neza cyane. Niba igishushanyo cyawe kiri mubintu bya UV-byoroshye, ibikoresho byo gusiga ntaho bihuriye nibintu ubwabyo bishaje kandi bigacikamo ibice. Ibi nabyize inzira igoye yo kuvugurura ubwiherero bwerekera mu majyepfo. Igipapuro cyasaga neza umwaka umwe, hanyuma gitera micro-crack kumunwa wagaragaye. Ifu ya grafite yari ikiriho mubice, ntacyo ikora kugirango ifate kashe hamwe.

Noneho hariho gukura kw'ibinyabuzima. Ibibyimba byoroshye. Imiterere yimiterere ya reberi irashobora kuba ahantu ho kororera. Ibintu bimwe byongeweho, harimo nubuvuzi bumwe na bumwe bwa grafite, birashobora kuvugwa ko bibuza ibi, ariko sinabonye ibimenyetso bifatika byigihe kirekire. Kenshi na kenshi, guhitamo ibikoresho bidahwitse nka silicone yo mu rwego rwohejuru, hamwe na grafite, cyangwa ikora grafite, ikora byinshi kugirango irambe ahantu hashobora kwibasirwa no guhakana gusa ubuso bwa spore. Ibipimo biramba hano ntabwo ari ubunyangamugayo gusa; ni ubunyangamugayo bw'isuku.

Kwishyiriraho: Akanya k'ukuri

Ubumenyi bwibintu byose kwisi birananirana mugihe cyo kwishyiriraho. Kuramba kwa gasketi kuramba kugenwa nuburyo yashyizwemo. Kubisabwa byogeramo idirishya, gasike ikenera kuramburwa cyangwa kuzunguruka mumurongo wa aluminium. Impagarara nyinshi mugihe cyo kwishyiriraho zitangiza ingingo zihoraho. Nabonye abayishyiraho bakoresha screwdriver kugirango basunike gasi ahantu, batobora iminwa. Ako kantu gato, mukarere gahora gahindagurika, gahinduka amarira mumezi atandatu. Igishushanyo ntigufasha aho.

Ibikwiye bigomba kuba byuzuye. Igipapuro gito cyane kumuyoboro kizaba kirambuye, cyoroshye kumpande zifunga, kandi birananirana hakiri kare. Imwe nini cyane izaterana, itere igitutu kitaringaniye kandi inzira ziva. Gushakisha kuva mubukora hamwe no kwihanganira gukuramo ibintu ni ngombwa. Aha niho izina ryikigo rifite akamaro. Kurugero, twashakishije ibifunga bisanzwe hamwe no gufunga imyirondoro ya producer nka Hamagara zitai yihuta ukora co., Ltd. kubindi bikorwa byubaka. Aho biherereye muri Yongnian, igice kinini cy’ibanze mu Bushinwa, ubusanzwe bisobanura kugera ku bidukikije binini by’ibikoresho n’ubuhanga bwo gukora. Mugihe ntakoresheje umwihariko wabo reberi ibicuruzwa, ihame rivuga: uruganda rwinjijwe muri urwo ruganda rukunze kugira igenzura rikomeye ku bikoresho fatizo hamwe no guhora biva mu mahanga, bigira ingaruka ku buryo butaziguye, bityo rero, amaherezo ya kashe. Urubuga rwabo, zitiFasTeners.com, yerekana kwibanda kubihambiriye, ariko indangagaciro yo gukora ibice byuzuye ni ngombwa.

Ubundi shyiramo nuance: amavuta. Byumvikane neza - gusiga amavuta yashizwemo amavuta. Ariko kugirango bikwiranye, gukoresha igisubizo cyamazi yisabune cyangwa amavuta meza ya reberi mugihe cyo kuyashyiraho ntabwo biganirwaho. Irinda gasike guhambira cyangwa gutanyuka nkuko inyerera mumuyoboro. Kuma-shitingi ya grafite, cyane cyane kumunsi ushushe, irashobora kuyifata no gukomera. Ibyo byangiritse ako kanya ntibishobora gutera kumeneka kumunsi wambere, ariko ni ingingo yananiwe gutsindwa.

Ingingo: Ikibazo cyo Kunanirwa cyane

Reka nsobanure urubanza rwihariye, rutesha umutwe. Umukiriya yashimangiye gasketi nziza ya siporo yubucuruzi ya cubicles. Twahawe ibintu bihenze, bitumizwa mu mahanga reberi, uzwiho kuramba gukabije. Yumvaga ari nziza - yoroshye, yuzuye, yasize intoki nziza ya grafite ku ntoki. Kwiyubaka byagenze neza. Ihute mbere y'amezi umunani. Imyitozo ngororamubiri yakoreshaga isuku ya chlorine ikaze buri munsi. Igipapuro cyari cyatakaje ubuso bwacyo, gihinduka imvi zijimye, kandi bigoye cyane. Inzugi zinyerera zatangiye gukomera, hanyuma ziranyeganyega. Bimaze gukurwaho, gaseke yari yoroheje; bafotoye aho guhinduka. Chlorine yari yibasiye iminyururu ya polymer, kandi grafite yari yicaye muri matrise yangiritse. Ikirango-cyiza cyane cyananiwe kubara ibidukikije byihariye bya shimi. Twabasimbuje ibintu byoroshye, birwanya imiti ya Viton ishingiye kuri gasike (nta grafite), kandi ibyo bimaze imyaka. Isomo ryari ubugome: kuramba ni imiterere-yihariye. Graphite yakemuye ubushyamirane, ntabwo irwanya imiti.

Ubunararibonye bwansunitse guhora nsaba, cyangwa ndetse nimyitwarire, byoroshye guhuza ibizamini. Niba uzi isuku isanzwe-umukoresha wa nyuma azakoresha, gerageza icyitegererezo cyibikoresho bya gaze yarengewe muri kiriya cyuma icyumweru. Reba kubyimba, gukomera, cyangwa kwangirika hejuru. Nintambwe yibanze irenga ibicuruzwa byose byo kwamamaza gasketi iramba.

None, Niki Mubyukuri Bikora Kuramba?

Nkurikije kunanirwa no gutsinda, dore ibyo mfata pragmatic. Kubintu byinshi byo guturamo byamadirishya yo guswera, urwego rwohejuru, rukomeye rwa silicone gasketi iruta grafite-yashizwemo reberi imwe muri rusange kuramba. Silicone isanzwe irwanya ubushyuhe bukabije, UV, nubushuhe birarenze. Kwiyunvira kwayo gushiraho gukira nibyiza. Gucuruza-ni ugutongana kwambere; birashobora kuba bike. Ariko kuri idirishya rifunze cyangwa ridakunze kwimuka, ibi ntaho bihuriye.

Niba ufite umuryango uremereye, ukunze kunyerera, noneho kugabanya guterana ni ngombwa. Icyo gihe, shyira imbere ibikoresho shingiro. Reba igishushanyo mbonera-cyiza, premium EPDM cyangwa igikoresho cyihariye cya termoplastique elastomer (TPE). Menya neza ko igishushanyo ari igice cyibice bigize ibice, ntabwo ari igifuniko gusa. Baza amakuru kuri compression yashizweho (ASTM D395) nubunini bwabyimbye mumazi hamwe nimiti isanzwe. Ibisobanuro bigomba kuvuga inkuru.

Hanyuma, ucunge ibiteganijwe. Nta gasi imara iteka. Mugukoresha cyane, ibidukikije bikaze, gutegura igenzura no gusimburwa nikimwe mubishushanyo biramba. Rimwe na rimwe, igisubizo kiramba cyane ni ugushushanya sisitemu kugirango gasike irinzwe - ikingiwe na UV itaziguye na spray iremereye, cyangwa gusimburwa byoroshye utabanje gusenya idirishya ryose. Ibyibandwaho ntibigomba kuba kubitangaza gusa Igishushanyo, ariko mugukora ibidukikije bibabarira, bikomeza gushyirwaho ikimenyetso. Aho niho hubatswe igihe kirekire, kirekire.
