Kutanthauzira kwazinthu ndi ukadaulo wapakatikati
Ma gaskets amtundu wa zinki amasinthidwa pamaziko a electrogalvanizing kuti apange filimu yamtundu wa utawaleza (yokhala ndi trivalent chromium kapena hexavalent chromium) yokhala ndi makulidwe a filimu pafupifupi 0.5-1μm. Kuchita kwake kotsutsana ndi dzimbiri ndikwabwinoko kuposa electrogalvanizing wamba, ndipo mtundu wapamtunda ndi wowala, ndi magwiridwe antchito komanso kukongoletsa.
Zida zazikulu ndi mawonekedwe
Zofunika: Q235 carbon steel, Q345 aloyi zitsulo, gawo lapansi kuuma HV150-250.
Mawonekedwe:
Kukana kwa dzimbiri: Palibe dzimbiri loyera pamayeso osalowerera amchere kwa maola 72-120, oyenera malo akunja kapena achinyezi;
Kutha kudzikonza: Pambuyo filimu yodutsayo ikang'ambika, gawo la hexavalent chromium lingathe kukonzanso malo owonongeka;
Kuzindikiritsa mitundu: Mitundu ya utawaleza imatha kugwiritsidwa ntchito kusiyanitsa milingo ya torque kapena magulu osiyanasiyana (monga makampani opanga magetsi).
Ntchito ndi zochitika zoyenera
Ntchito:
Kugonjetsedwa ndi dzimbiri monga kutsitsi mchere ndi asidi mvula kwa nthawi yaitali, ndi moyo utumiki 3-5 nthawi wamba electroplating nthaka;
Kuzindikirika kowoneka bwino, kukonza kosavuta kwa zida ndi kasamalidwe.
Zochitika:
Zida zamagetsi zakunja (monga ma bolts a nsanja), engineering ya m'madzi (kulumikizana kwa sitima yapamadzi), makina amankhwala (tanki flange).
Kuyika ndi kukonza
Kuyika:
Wrench ya torque iyenera kugwiritsidwa ntchito kuti iwonetsetse kuti filimuyo isanakwane kuti isagwe chifukwa cha extrusion yochulukirapo;
Kulumikizana mwachindunji ndi zitsulo zogwira ntchito monga aluminiyamu ndi magnesium ndizoletsedwa kuteteza galvanic corrosion.
Kusamalira:
Pewani kugwiritsa ntchito zotsukira acidic, tikulimbikitsidwa kupukuta ndi zosungunulira zandale;
Ma gaskets a hexavalent chromium passivation amayenera kutsatira malamulo a chilengedwe (monga malamulo a EU REACH), ndipo ma gaskets opanda chromium ndi oyenera kumafakitale azakudya ndi mankhwala.
Gulani malingaliro
Pazinthu zomwe zili ndi zofunika kwambiri zachilengedwe, sankhani trivalent chromium passivation kapena chromium-free passivation process;
Gwiritsani ntchito ma gaskets achikuda a zinki mosamala m'malo otentha kwambiri (> 100 ℃), chifukwa filimu yodutsa imatha kuwola ndikulephera.
Kufananiza ndi kusankha kalozera wa gaskets zazikulu zitatu
| Mtundu | Electroplated kanasonkhezereka gasket | Gasket yamitundu yosiyanasiyana | Gasket yakuda yamphamvu kwambiri |
| Ubwino waukulu | Mtengo wotsika, wamphamvu zosunthika | High dzimbiri kukana, chizindikiritso mtundu | Mphamvu yapamwamba, kukana kutentha kwakukulu |
| Mayeso opopera mchere | Maola 24-72 opanda dzimbiri loyera | Maola 72-120 opanda dzimbiri loyera | Maola 48 opanda dzimbiri |
| Kutentha koyenera | -20 ℃ ~ 80 ℃ | -20 ℃ ~ 100 ℃ | -40 ℃ ~ 200 ℃ |
| Zochitika zenizeni | Makina wamba, chilengedwe chamkati | Zida zakunja, chilengedwe chonyowa | Injini, zida zogwedezeka |
| Chitetezo cha chilengedwe | Njira yopanda cyanide imagwirizana ndi RoHS | Hexavalent chromium iyenera kutsatira REACH, trivalent chromium ndiyotetezeka ku chilengedwe. | Palibe kuwononga zitsulo zolemera |
Malingaliro osankha:
Zofunikira pazachuma: Electroplated kanasonkhezereka gaskets, oyenera zochitika wamba mafakitale;
Malo okhala ndi dzimbiri: Ma gaskets achikuda, amaika patsogolo njira ya chromium yopanda chromium;
Kulemera kwakukulu / kutentha kwakukulu: Ma gaskets akuda amphamvu kwambiri, ofananira mphamvu ya bawuti (monga 42CrMo ya 10.9 grade bolts gasket).
Lumikizanani nafe
Zogwirizana zodziwika bwino
Nangula wooneka ngati 7 (zobowola zooneka ngati 7)
Nangula wa mawonekedwe 7 amatchulidwa chifukwa mbali imodzi ya bolt imapindika mu mawonekedwe a "7". Ndi imodzi mwa mitundu yofunikira kwambiri ya mabawuti a nangula. Kapangidwe kake kamakhala ndi ndodo ya ulusi ndi mbedza yooneka ngati L. Gawo la mbedza limakwiriridwa mu maziko a konkire ndikulumikizidwa ku zida kapena kapangidwe kachitsulo kudzera mu mtedza kuti akwaniritse kukhazikika kokhazikika.
