1. Gabatarwa

A cikin aikace-aikacen masana'antu na zamani, amincin dogon lokaci na haɗin gwiwa da aka kulle ya dogara da tasiri sosai lalata kariya kuma anti-tsatsa yi. Gilashin zinc na al'ada da ɗumbin ɗumbin ɗumbin ɗumbin ɗumbin yawa sau da yawa suna raguwa a cikin matsanancin yanayi kamar abubuwan more rayuwa na bakin teku, dandamalin teku, tsire-tsiren sinadarai, da ƙananan motocin da ke fallasa ga gishirin hanya. Dacromet flange kusoshi hada tsarin fa'idodin ƙirar flange-head tare da fice tsatsa-tsatsa kuma anti-lalata Properties na zinc-aluminum flake coatings.

Dacromet (wanda kuma aka sani da murfin flake na zinc) ba na lantarki ba ne, magani na tushen ruwa. Yana ajiye wani bakin ciki mai ƙarfi amma mai inganci na zinc da flakes na aluminium wanda aka haɗa ta matrix chromate, yana ba da na musamman. kariyar shinge, hadaya cathodic kariya, kuma sha'awar warkar da kai. Aiwatar da kusoshi na flange, wannan shafi yana ba da abin dogaro na dogon lokaci tsatsa juriya ba tare da ɓata dacewa da zaren zaren ba, daidaiton juzu'i, ko gabatar da haɗarin haɓakar hydrogen.

Hoto 1. Maɗaukakin ƙarfi mai rufaffiyar Dacromet tare da ƙaƙƙarfan ƙaƙƙarfan lalatawar azurfa-launin toka.

2. Flange Bolts da Dacromet Coating Technology

Kullin flange yana da flange na madauwari na haɗe a ƙarƙashin shugaban hexagonal wanda ke aiki azaman ginin ginin ciki. Wannan ƙira yana rarraba ƙarfi mai ƙarfi a kan babban saman ƙasa mai ɗaukar nauyi, yana rage lalacewa da haɓaka juriya ga sassautawar girgiza. Lokacin da waɗannan kusoshi suka karɓi shafi na Dacromet, haɗin gwiwar yana haifar da maɗauri wanda ke ba da amincin injina da inganci anti-tsatsa kuma lalata-resistant yi. Rubutun bakin ciki (yawanci 5-12 μm) yana kula da madaidaicin lissafi na zaren.

2.1 Rubutun Rubutu da Tsari

Dacromet wani tarwatsewar ruwa ne na flakes na zinc, flakes na aluminum, da chromium oxides. Tsarin da ba na lantarki ya ƙunshi: (1) tsaftacewar ƙasa ba tare da tsintsawar acid ba; (2) aikace-aikace ta hanyar tsoma-spin, tsoma-magudanar ruwa ko fesa; da (3) warkewa a kusan 300°C don haɗa flakes ɗin zuwa yadudduka masu haɗuwa. Sakamakon ƙarfe na azurfa-launin toka fim yana samar da Multi-Layer oxidation juriya kuma abin dogara shamaki danshi.

2.2 Hanyoyin Kariyar Lalacewa

Dacromet yana samun na musamman anti-lalata aiki ta hanyoyin daidaitawa guda uku:

Kariyar Kariya: Zuciyar zinc da flakes na aluminum suna haifar da shingen jiki na labyrinthine wanda ke hana ruwa, oxygen, da ions masu lalata kamar chlorides.
Kariyar Hadaya (Katolika): Filayen Zinc sun fi lalata, suna aiki azaman anode na hadaya wanda ke kare ma'aunin ƙarfe daga samuwar tsatsa.
Ciwon kai da Warkar da Kai: Mahalli na Chromate suna samar da fim mai ɗorewa kuma suna iya ƙaura zuwa ƙananan karce, suna ba da ci gaba rigakafin tsatsada iya gyara kai.
