• • Gwajin kauri na Ultrasonic: Matsakaicin ragowar kauri 29.98mm (babu asara mai aunawa).

• • Duban gani: Babu rami ko canza launin - wuce gwajin gishiri na sa'o'i 1000 (ASTM B117) ba tare da lahani ba.

• • Kudin kulawa: 0 yuan (kawar da shafi na shekara-shekara).

2. Ingantaccen Aiki

• • Lokacin shigarwa: Rage zuwa 3 hours / shugaban (adawar 5 hours / shugaban, duka 50 hours don 10 kawunansu).

• • Amfanin makamashi: Rage zuwa 1.1kWh/m³ (9% raguwa)- tanadin wutar lantarki na shekara 9,125 yuan (500m³/rana × 365 kwanaki × 0.1kWh/m³ × 0.5 yuan/kWh).

• • Nauyin jirgin ruwa: Rage zuwa 3.8 ton (27% mai sauƙi)- sake zagayowar kula da famfo daga 6 watanni zuwa 12 watanni.

3. Jawabin mai amfani

• • Ƙungiyar kulawa: “Kawukan aluminium ba sa buƙatar sutura, rage aikinmu da kashi 80%.”

• • Manajan Ayyuka: “Adana makamashi da shigarwa cikin sauri sun inganta ROI ɗin mu da 25%.”

5.4 Ƙarshen Aikin

Canja zuwa 5083 shugabannin fayafai na aluminium masu zafi masu kauri sun warware ainihin ma'aunin zafi na masana'anta. Sama da 18 watanni, aikin da aka cimma:

• 100% juriya na lalata (babu buƙatar kulawa).

• 34.6% ƙananan zuba jari na farko da 9% tanadin makamashi na shekara-shekara.

• 56% sauri shigarwa da 27% nauyi jirgin ruwa.

Maƙerin tun daga lokacin ya faɗaɗa amfani da kawunan aluminum zuwa 50+ tankuna, sa ran ajiyewa 200,000 yuan in 5 shekaru.

Ƙarshe: Fayafai na Aluminum Mai Kauri Mai Kauri - Makomar Kananan Kangin Jirgin Ruwa

Fayafai na aluminium masu kauri masu kauri, musamman ma 5083 jerin, sun zama kayan da aka fi so don ƙananan jiragen ruwa na matsa lamba saboda su aikin da za a iya daidaitawa, fa'idodin tsadar rayuwa, da bin ka'idojin duniya. Nasarar su ta samo asali ne a ciki:

1. Kimiyyar Material: Daidaitaccen sarrafawa Mg/Mn/Cr abun ciki yana daidaita ƙarfi, juriya na lalata, da formability-magana da gazawar gargajiya karfe.

2. Fasahar Tsari: Mirgina mai zafi da yawa da ƙullawa suna tabbatar da daidaiton girma (kauri haƙuri ≤± 0.25mm) da daidaitattun kayan aikin injiniya.

3. Darajar Tattalin Arziki: 21.7% ƙananan farashin rayuwa na shekaru 5 fiye da bakin karfe, 18% ƙasa da carbon karfe-ba da ROI na zahiri don kamfanoni.

Daura, tare da ci gaban masana'antu kamar desalination na ruwan teku (girma na shekara-shekara 8%), abinci/magunguna (10%), da sabon makamashi (15%), Bukatar fayafai na aluminium masu kauri masu kauri za su ci gaba da tashi. Sabbin abubuwa na gaba-kamar AI-ingantattun sigogin mirgina mai zafi (rage kauri haƙuri zuwa ± 0.1mm) da Sc-added alloys (ƙara ƙarfin ƙarfi zuwa 350MPa)— za su ƙara faɗaɗa iyakokin aikace-aikacen su.

Idan kana buƙatar keɓance ƙarin fayafai na aluminium masu kauri masu kauri don ƙananan shugabannin jirgin ruwa na matsa lamba, don Allah a samar:

• Matsin ƙirar jirgin ruwa (MPa) da girma (m³)

• Nau'in matsakaici (e.g., ruwan teku, acid, abinci) da zafin aiki (℃)

• Diamita na kai (mm) da siffa (siffar tasa, elliptical)

Ƙungiyarmu za ta samar da wani rahoton zaɓin kayan abu na musamman, lissafin kauri, da kuma tsarin lokaci na masana'antu don biyan takamaiman bukatunku.

Karin bayani: Kamus na Mabuɗin Sharuɗɗan

• Faifan aluminum mai kauri mai kauri: Aluminum Disc tare da kauri ≥10mm, wanda aka samar ta hanyar mirgina mai zafi da yawa (zazzabi 300-480 ℃).

• Ƙananan jirgin ruwa: Jirgin ruwa mai matsa lamba ≤2.5MPa da girma ≤5m³ (da GB 150).

• Damuwa lalatawar fata (SCC): Fatsawar da ke haifar da haɗuwar damuwa mai ƙarfi da kuma gurɓataccen yanayi (na kowa a Cl⁻ don bakin karfe).

• Gwajin Hydrostatic: Gwajin matsa lamba ta amfani da ruwa don tabbatar da matsewar ruwa da ƙarfin ɗaukar matsi (da GB 150.4).

• Weld hadin gwiwa yadda ya dace (f): Ratio na weld ƙarfi zuwa tushe ƙarfin abu (0.85 don cikakken radiyo welds).

• Izinin lalata (C₁): Ƙarin kauri don lissafin lalata yayin sabis (2-3mm don muhallin Cl⁻).
