Lwaki Screws Yo Za Sandwich Panel Zikulukuta: Ensobi 3 Enkulu mu Kulonda Washer EPDM
Mu mulimu gw’okuzimba ebyuma, pulojekiti nnungi nnyo ng’ekifo kyayo ekisinga obunafu. Ebiseera ebisinga, ensonga eyo eba kitundu kitono nnyo, ekibuusibwa amaaso: theEkyuma eky’okunaaba ekya EPDMku sikulaapu zo ez'okwesima-.
KuDongchao Hardware (Ebikulukusi bya DC) ., twekenneenyezza ebikumi n’ebikumi by’obusolya obulemererwa. Okwemulugunya okusinga "okukulukuta kw'akasolya" tekuva ku bipande byennyini, wabula okuvunda kwa seals ez'omutindo ogwa wansi oba torque y'okussaako etali ntuufu. Wano waliwo okumenya okw’ekikugu ku ngeri y’okukakasa nti ssiringi etayingiramu mazzi okumala emyaka 15+.
1. Sayansi w’ebintu: Virgin EPDM vs. Recycled Rubber
Si ba black washers zonna nti zitondeddwa nga zenkanankana. Sikulufu nnyingi ez’omutindo gwa mbalirira-zikozesa emipiira oba PVC blends ezizzeemu okukozesebwa okukendeeza ku nsaasaanya.
Okulemererwa:Kapiira azzeemu okukozesebwa temulina bunywevu bwa UV. Wansi w’ebbugumu ery’amaanyi ery’akasolya ak’ekyuma, ebyuma bino eby’okwoza bifuuka bikutuka, byatika, era ne bikendeera mu myezi 24, ne birekawo ekituli amazzi we gasobola okuyita ku mutwe gwa sikulaapu.
Omutindo gwa DC:TukozesaEbirimu ebya waggulu-Ebirimu Virgin EPDM. Kikuuma elasticity mu bbugumu erisukkiridde okuva ku-40 diguli okutuuka ku 120 degree. Ensengekera ya molekyu yaayo ekoleddwa okusobola "okujjukira-okukwata" ekikondo kya sikulaapu, okukakasa nti ne bwe kiba nti ekipande ky'ekyuma kigaziwa era ne kikendeera, ssimu esigala nga temenyese.
2. Omutego gwa "Over-Torque": Profaayili y'okunyigiriza entuufu
Ensobi etera okubaawo mu kifo kwe kuvuga sikulaapu mu buziba ennyo. Abassaako batera okulowooza nti "okunyweza kisingako obukuumi," naye eno nsobi ya kufa ku kuziyiza amazzi.
Wansi wa-Evugibwa:Ekyuma eky’okunaaba tekinnanyiga kimala kukwatagana na biwujjo by’ekyuma.
Okusukka-Evugibwa:Flange emenya EPDM, n'ewaliriza empenda "mushroom" oba okukyusakyusa waggulu. Kino kikola ekikopo ekitono ekikung’aanya amazzi agayimiridde, ne kyanguya okukulukuta kwa galvanic.
"Ekifo Ekiwooma":EPDM erina okunyigirizibwa okutuusa lw’erabika ng’eyiseeko katono ku mabbali ga flankisi y’ekyuma, naye n’esigala nga nnyimpi ku kipande.
3. Lwaki Double-Thread Screws Ye Pro's Choice
Ku bipande bya sandwich ebinene (ebyoya by'amayinja oba EPS), sikulaapu za wuzi emu- eza bulijjo zisobola okulwanagana ne "okwawula ebipande."
FfeDouble-Thread Self{1}}Ebikulukusi by'okusimazirina obuwuzi obw’okubiri wansi w’omutwe nga gulina eddoboozi erisingako. Dizayini eno esiba ekipande eky'ebweru n'ekizimbe eky'omunda wamu, ne kiremesa "pumping effect" ereetebwa emigugu gy'empewo okukkakkana nga gisumuludde enkwata ya washer.
Ebikwata ku by'ekikugu & Size Chart
Okusobola okukuyamba okulonda ekisiba ekituufu ku pulojekiti yo ey’okuzimba akasolya, laba data yaffe eya yinginiya etuukiridde wansi:
| Erinnya ly’ebintu | Gauge & Diameter | Obuwanvu Obuwanvu | Obusobozi bw’okusima | Ebikwata ku washer | Okusaba Okusookerwako |
| Hex Double Thread Sikulufu | #12 (mmita 5.5) / #14 (mm 6.3) | 75mm - 350mm | Okutuuka ku 12.5mm Ekyuma | 16mm / 19mm EPDM | Ebipande bya Sandwich ebizito |
| Sikulufu y’okutunga akasolya | #10 (mmita 4.8) / #12 (mm 5.5) | 20mm - 35mm | 2mm - 4mm Ekyuma | 14mm EPDM Bonded | Okusiba Ebiyungo mu Lap |
| Sikulufu ya Tile ya Resin | #14 (mmita 6.3) | 75mm - 150mm | Embaawo / Ekyuma ekitangaavu | Enkoofiira etayingiramu mazzi + EPDM | Obuveera/Resin obw’amayinja |
Professional Lab Data (Okulondoola omutindo) .
Buli kibinja kya Dongchao EPDM-bonded washers kigezesebwa nnyo okusobola okutuukana n’omutindo gw’ensi yonna ogw’okuzimba:
Obukaluba (Olubalama A): .65-75 (Erongooseddwa okusiba ekyuma-ku kyuma).
Amaanyi g’okusika:Okusinga oba okwenkana 10.5 MPa.
Obuziyiza bwa Ozone:50 pphm (Tewali nnyatika wansi w’okubikkulwa okumala essaawa 72).
Obuziyiza Okufuuyira Omunnyo:Esangibwa n’ekizigo kya Ruspert oba Dacromet okusobola okukuuma essaawa 500-1500.
Mu bufunze bw’omukugu
Toleka washer ya doola 0.05 kwonoona ndagaano ya doola 50,000 ey’okuzimba akasolya. Okulonda ensengeka entuufu eya EPDM n'okukakasa nti torque entuufu ey'okussaako ze ngeri bbiri ezisinga okusaasaanya ssente-okuziyiza okukulukuta.
Okwetaaga obuwanvu obw'ennono ku bipande by'okuziyiza eby'okungulu-?Dongchao Hardware ekuguse mu bisiba ebiwanvu eby'enjawulo (okutuuka ku mmita 350) amakolero agasinga bye gatasobola kukola.
