Ifestile yeshawari yerabha yegraphite gasket ukuqina? 

Uyabona lo mbuzo uvela kwii-specs okanye kumxhasi, kwaye ingcamango ekhawulezileyo ayikho malunga nepropati enye yezinto eziphathekayo-imalunga nenyaniso yonke engcolileyo yento eyenzekayo xa ubeka itywina phakathi kwefestile ehambayo kunye nesakhelo sokuhlamba, ulindele ukuba ihlale iminyaka echasene nobushushu, amanzi, kunye nokunyanzeliswa rhoqo. Igama elithi ‘graphite’ lidla ngokuphoswa njengothuli lomlingo, ekucingelwa ukuba liphuculwe, kodwa ngaba kunjalo? Ukususela kwixesha lam lofakelo kunye nokutshintshwa, incoko ehlala ixesha elide ayifane ibe malunga ne-gasket ngokwayo. Imalunga nenkqubo, okusingqongileyo, kwaye ngokungafihlisiyo, ukungaqondani okuqhelekileyo ekuthengeni.

Isithembiso seGraphite vs. On-Site Reality

Abathengisi bathanda ukwenza irabha efakwe kwigraphite. I-pitch yokuthengisa ihlala imalunga nokunciphisa ukungqubana, ukutywinwa okungcono phantsi koxinzelelo, kunye nokuphila ixesha elide. Kwaye ngokwethiyori, iyavakala. Igraphite sisithambiso esiqinileyo. Kwisicelo esiguquguqukayo esifana nocango lweshawa apho ifestile okanye ipaneli isilayidi okanye ii-pivots, ukunciphisa ukukhuhlana kwindawo yokudibanisa i-rubber gasket kufuneka kuthintele ukukrazula okanye ukonakala kwangaphambili. Kodwa nantsi i-hiccup yokuqala: umgangatho kunye nokusasazeka kwegraphite. Ndibone iibhetshi apho igraphite ibonakala ngathi iphantse yaphuma, ishiya i-smudgy intsalela kwiglasi emva kweenyanga ezimbalwa zokusetyenziswa, ngelixa irabha engaphantsi ibuyela kwisiseko sayo, iba yi-tacky okanye i-brittle. Inzuzo yokuqina? Ayinamsebenzi, ukuba ayikho embi. Yayingeyiyo igraphite eyasilelayo; yayiyinkomponi eyayidityaniswe kuyo.

Emva koko kukho isethi yoxinzelelo. Le yeyona inkulu. I-gasket igutyungelwa phakathi kwesakhelo se-aluminiyam kunye nephaneli yeglasi. I-EPDM efanelekileyo okanye umxube we-silicone kufuneka ubuyele umva. Yongeza igraphite kumxube, kwaye inokuguqula imemori yepolymer. Ndikhumbula iprojekthi malunga neminyaka emithathu emva apho sasebenzisa i-premium, iphrofayili ye-EPDM efakwe kwi-graphite yoluhlu lweendawo ezivaliweyo zeshawari zehotele eziphezulu. Ukutyibilika kokuqala kwakumnandi—kuthe cwaka, kumtyibilizi. Kodwa emva kweenyanga ezili-18 zokusetyenziswa rhoqo kwindawo efumileyo, neshushu, ii-gaskets zathatha isethi esisigxina. Abazange babuye umva. Itywina yaba ngumgca obhityileyo, othe tyaba, kwaye saqala ukufumana iicallbacks zokuphuma kwamanzi. Igraphite iwuncedile umphezulu wokutyibilika, kodwa ngaba yabeka esichengeni ukomelela kwesixhobo kuxinzelelo oluqhubekayo? Kuloo meko, kwakubonakala kunjalo.

Oku kukhokelela kwindawo ebanzi: ikhompawundi yerabha esisiseko yinkosi. Igraphite sisongezo, isilungisi. Ukuba uqala nge-EPDM ephantsi okanye i-rubber mix mix, ukongeza i-graphite kufana nokubeka i-band-aid kumcimbi wesakhiwo. Ndithanda ukuthandabuza iispecs ezibiza nje i-graphite gasket ngaphandle kokuchaza imathiriyeli esisiseko, ukuqina kwayo (i-Shore A), kunye noluhlu olulindelekileyo lobushushu benkonzo. Umbuzo wokuqina uyatshintsha kwi-Ingaba igraphite ilungile? ukuba yintoni le graphite ixutywe nayo, yaye ngayiphi injongo kanye?

Uhlaselo lokusiNgqongileyo: Ayinamanzi nje

Xa sithetha ngeegaskets zeshawari yefestile, 'ishawa' ligama elisebenzayo, elikhohlakeleyo. Asiyonkungu ethambileyo. Ngumphunga oshushu, ukukhwela ibhayisekile okushushu ukusuka kwiglasi ebandayo ukuya kumanzi ashushu, ukuvezwa kweekhemikhali kwiisepha, iishampu, kwaye ngakumbi izisusi zelimescale eziqatha okanye izicoci ezineasidi. Umaleko wegraphite ngokwawo unokuba sesichengeni. Kwiindawo ezinamanzi anzima, iidipozithi zeminerali (i-limescale) zinokubophelela kwindawo ene-textured kancinane, ethanjiswayo ye-graphite gasket ngokuqina ngakumbi kune-silicone ecacileyo. Ufumana le gritty, uqweqwe abrasive ukwakha. Ngokuhamba kwexesha, ngalo lonke ixesha ifestile isilayidi, ayisosenzo esigudileyo segraphite-kwiglasi kwakhona; itsala amasuntswana abrasive kuyo yomibini imiphezulu, inxibe igasket kwaye ikwazi ukukrwela umjelo weglasi.

Ukuvezwa kwe-UV ngomnye umbulali othuleyo, osoloko engahoywa ngofakelo lwangaphakathi. Kodwa iifestile ezininzi zegumbi lokuhlambela zifumana ilanga elithe ngqo. I-EPDM eqhelekileyo idume kakubi nge-UV; iyaqhekeka kwaye ithoba. I-Silicone iyiphatha ngcono kakhulu. Ukuba igraphite yakho ikwisiseko se-UV-sesichaphazeleka, inzuzo yokuthambisa ayibalulekanga xa imathiriyeli ngokwayo ithanda kwaye yahlukana. Ndifunde oku kabuhlungu ekulungiseni igumbi lokuhlambela elijonge emazantsi. I-gaskets yayibukeka intle unyaka, emva koko iphuhlise i-micro-cracks ecaleni komlomo oveziweyo. Umgubo wegraphite wawusekho kwezo ntanda, ungenzi nto ukudibanisa itywina.

Kwaye ke kukho ukukhula kwebhayoloji. Ukungunda kunye nokungunda. Ubume bemibhobho yezinye iikhompawundi zerabha inokuba yindawo yokuzalela. Ezinye izongezo, kubandakanywa unyango oluthile lwegraphite, zinokuthi zithintele oku, kodwa andizange ndibone ubungqina bexesha elide. Ngokuthe gqolo, ukhetho lwemathiriyeli engeyiyo i-porous efana ne-silicone ekumgangatho ophezulu, enegraphite okanye engenazo, yenze ngakumbi ukuqina kwimeko-bume ethanda ukungunda ngokukhanyela umphezulu wokubamba i-spores. Imetriki yokuqina apha ayiphelelanga nje ekufezekeni komatshini; yimfezeko ecocekileyo.

Ukufakela: Ixesha leNyaniso

Yonke inzululwazi yezinto eziphathekayo emhlabeni iyasilela kwindawo yokufakela. Ukuqina kwe-gasket kumiselwe kwangaphambili ukuba ifakwe njani. Kwizicelo zeshawari zefestile, i-gasket isoloko ifuna ukolulwa okanye ifakwe kwitshaneli yesakhelo se-aluminium. Uxinzelelo oluninzi ngexesha lofakelo luzisa amanqaku asisigxina oxinzelelo. Ndikhe ndabona abafakeli besebenzisa i-screwdriver ukuze bafake i-gasket endaweni, befaka umlebe wokutywina. Elo nick lincinci, kwindawo eguqukayo rhoqo, liba sisikrawu kwiinyanga ezintandathu. Igraphite ayincedi apho.

Ukulingana kufuneka kuchaneke. I-gasket encinci kakhulu kwitshaneli iya kolulwa kakhulu, ibhityile kwincam yokutywina, kwaye ingaphumeleli kwangoko. Enye enkulu kakhulu iya kuhlangana, idale uxinzelelo olungalinganiyo kunye neendlela ezivuzayo. Ukufumana imveliso evela kumvelisi kunye nokunyamezelwa okungaguqukiyo kwe-extrusion kubalulekile. Apha kulapho isidima senkampani sibalulekile. Umzekelo, siye safumana iziqhoboshi ezisemgangathweni kunye neeprofayili zokutywina kumvelisi onje I-Sunnian Zitai Festener Fishaner Comment Com. kwezinye izicelo zokwakha. Indawo abakuyo eYongnian, eyona siseko sisezantsi eChina, ihlala ithetha ukufikelela kwindawo enkulu yezinto eziphilayo kunye nobuchule bokwenza izinto. Ngelixa ndingakhange ndisebenzise ingcaciso yabo irabha graphite gasket Iimveliso, umgaqo uphethe: umenzi ofakwe kuloo hub yemizi-mveliso uhlala enolawulo olungqongqo kwiibhetshi zemathiriyeli ekrwada kunye nokungaguquguquki kwe-extrusion, okuchaphazela ngokuthe ngqo ukufakela kwaye, ngenxa yoko, ukuqina ekugqibeleni kwetywina. Indawo yabo, I-Zitafasteners.com, ibonisa ugqaliselo kwiifasteners, kodwa umgaqo osisiseko wokuvelisa wamacandelo achanekileyo ufanelekile.

Enye i-nuance yokufakela: i-lubrication. Ivakala iyimpoxo-yokuthambisa i-lubricant-efakwe kwi-gasket. Kodwa ngokufanelekileyo, ukusebenzisa isisombululo samanzi esepha okanye i-lubricant yerabha efanelekileyo ngexesha lofakelo ayinakuxoxisana. Ikhusela i-gasket ekubopheni okanye ukukrazula njengoko i-slide kwitshaneli. Ukomisa i-graphite gasket, ngakumbi ngemini eshushu, kunokubangela ukuba ibambe kwaye ibophe. Loo monakalo wangoko awunakubangela ukuvuza ngosuku lokuqala, kodwa yindawo eqinisekisiweyo yokusilela.

Ingongoma: Ukungaphumeleli koMsebenzi oPhezulu

Makhe ndichaze imeko ethile, ekhathazayo. Umxhasi unyanzelise eyona gasket ilungileyo yeetyhubhile zeshawa yorhwebo. Sabonelelwa ngexabiso eliphezulu, elithengwe kumazwe angaphandle irabha graphite gasket, inconywa ngokuhlala ixesha elide. Yayivakala imnandi—igudile, ixinene, ishiya umkhondo ogqibeleleyo wegraphite eminweni. Ukufakela kuhambe kakuhle. Ukukhawuleza ukuya phambili kwiinyanga ezisibhozo. Indawo yokuzivocavoca ibisebenzisa izicoci ezinobundlobongela ezisekwe kwiklorin yonke imihla. Iigaskets ziye zaphulukana nokutyibilika kwazo, zajika zaba ngwevu, kwaye zaqina ngakumbi. Iingcango ezityibilikayo zaqala ukuncamathela, zaza zashukuma. Ekususweni kwayo, iigaskets zazine-brittle; baqhwaba endaweni yokugoba. Iklorini yayihlasele amatyathanga epolymer, kwaye igraphite yayihleli nje kwimatrix eyonakeleyo. Ileyibhile ephezulu yokusebenza ayiphumelelanga ukujongana nemeko ethile yeekhemikhali. Sazitshintsha safaka i-gasket esekwe kwi-Viton elula, enganyangekiyo ngamachiza (akukho graphite), kwaye ezo ziye zahlala iminyaka. Isifundo besinoburhalarhume: ukuqina kuxhomekeke kwimeko. I-graphite yalungisa ukungqubana, hayi ukumelana neekhemikhali.

La mava andityhale ukuba ndisoloko ndicela, okanye ndiqhube iimvavanyo ezilula zokuhambelana. Ukuba uyabazi abacoci abaxhaphakileyo abaza kuqeshwa ngumsebenzisi wokugqibela, vavanya isampulu yezinto zegasket ezintywiliselwe kweso sicoci kangangeveki. Khangela ukudumba, ukuqina, okanye ukuthotywa komphezulu. Linyathelo elisisiseko elidlula yonke ijargon yokuthengisa malunga nayo ukuqina gasket.

Ke, Yintoni Ngokwenene Esebenza Ubomi Obude?

Ngokusekwe kwiintsilelo kunye nempumelelo, nantsi ukuthatha kwam ipragmatic. Kuninzi lwezicelo zeshawa yefestile yendawo yokuhlala, umgangatho ophezulu, igasket yesilicone eyomeleleyo ikholisa ukodlula irabha emiliselwe yigraphite xa iyonke. ukuqina. Ukuchasana kwe-silicone kubushushu obugqithisileyo, i-UV, kunye nokufuma kuphezulu. Ukubuyiswa kwayo kwesethi yoxinzelelo kuhle kakhulu. I-trade-off yingxabano yokuqala; inokuba ibambeke kancinci. Kodwa ngefestile enehenjisi okanye eshukunyiswa rhoqo, ayisebenzi.

Ukuba unocango olunzima, oluhlala lutyibilika, ke ukucutha ukukruquka kubalulekile. Kwimeko apho, beka phambili izinto ezisisiseko kuqala. Khangela i-graphite-enhanced, i-premium EPDM okanye i-elastomer ye-thermoplastic eyenziwe ngokukodwa (TPE). Qinisekisa ukuba igraphite yinxalenye edityanisiweyo yekhompawundi, ingeyiyo nje into yokwambathisa. Cela idatha kwi-compression set (ASTM D395) kunye nokudumba kwevolumu emanzini kunye neekhemikhali eziqhelekileyo. Iimpawu kufuneka zibalise ibali.

Ekugqibeleni, lawula ukulindela. Akukho gasket ihlala ngonaphakade. Kwindawo ephezulu yokusetyenziswa, enobundlobongela, ukucwangciswa kokuhlolwa kunye nokutshintshwa kuyingxenye yoyilo oluzinzileyo. Ngamanye amaxesha, esona sisombululo sisisigxina siyila inkqubo ukuze i-gasket ikhuselwe-ikhuselwe kwi-UV ethe ngqo kunye ne-spray enzima, okanye ithathelwe indawo ngokulula ngaphandle kokudiliza yonke iyunithi yefestile. Ugxininiso akufanele lube kwimimangaliso nje i-phytimet gasket, kodwa ekudaleni indawo exolelayo, egcinekayo yokutywina ejikelezileyo. Kulapho ukuqina kokwenyani, ixesha elide kwakhiwa.
