Production tsari na high quality-epoxy gilashin fiber jirgin

A. Surface shiri da magani na epoxy gilashin zane laminate kayayyakin

1. Bayan an zana saman jan ƙarfe kuma an tsara shi don samar da kewayawa, gwada rage jiyya da tuntuɓar saman PTFE. Ya kamata ma’aikaci ya sa safar hannu mai tsabta kuma ya sanya fim ɗin interlayer akan kowane allo don wucewa zuwa hanya ta gaba.

2. The etched PTFE surface yana da isasshen roughness ga bonding. Inda za a ɗaure zanen gado ko laminate da ba a buɗe ba, ana ba da shawarar a bi da saman PTFE don samar da isasshen abin da aka makala. Hakanan ana iya amfani da abubuwan sinadaran da aka yi amfani da su a cikin tsarin shirye-shiryen pth don maganin saman. Ya ba da shawarar etching na plasma ko sinadarai masu ɗauke da sodium, kamar FluroEtch®byActon, TetraEtch®byGore, da Bond-Prep®byAPC. Ana samar da takamaiman fasahar sarrafawa ta mai bayarwa.

3. Jiyya na jan karfe ya kamata ya tabbatar da mafi kyawun haɗin gwiwa. Maganin da’ira na jan ƙarfe monoxide mai launin ruwan kasa zai ƙarfafa siffar saman don sauƙaƙe haɗin sinadarai tare da m TacBond. Tsarin farko yana buƙatar mai tsabta don cire ragowar da man magani. Bayan haka, ana yin ƙaƙƙarfan etching tagulla don samar da daidaitaccen wuri mara kyau. Lu’ulu’u na allurar oxide mai launin ruwan kasa suna daidaita layin haɗin gwiwa yayin aikin lamination. Kamar kowane tsarin sinadarai, isasshen tsaftacewa bayan kowane mataki na tsari ya zama dole. Ragowar gishiri zai hana mannewa. Ya kamata a kula da zubar da ruwa na ƙarshe kuma ƙimar pH ya kamata a kiyaye ƙasa 8.5. Dry Layer ta Layer kuma tabbatar da cewa saman bai gurbata da mai a hannun ba.

B. Mai rufi da lamination

Shawarar haɗin kai (matsawa ko latsa) zafin jiki: 425°F (220°C)

Yin burodin plies a 1.250oF (100 ° C) don kawar da danshi. Ana adana yadudduka a cikin yanayi mai ƙarfi kuma ana amfani da su cikin sa’o’i 24.

2. Ya kamata a yi amfani da filin matsa lamba tsakanin katakon kayan aiki da na’urar lantarki ta farko ta yadda za a iya rarraba matsa lamba a cikin kwamiti mai kulawa. Babban wuraren wutar lantarki da ke cikin jirgi da kuma a cikin allon da za a cika za su mamaye filin. Hakanan filin na iya haɗa yanayin zafi daga waje zuwa tsakiya. Don haka, kauri tsakanin allon kulawa da allon kulawa yana haɗuwa.

3. Dole ne allon ya ƙunshi siraren TACBOND wanda mai samarwa ya samar. Yi hankali don hana kamuwa da cuta lokacin yankan yadudduka na bakin ciki da tari. Dangane da ƙirar kewayawa da buƙatun cika, 1 zuwa 3 na bakin ciki manne yadudduka ya zama dole. Ana amfani da yankin da za a cika da buƙatun dielectric don ƙididdige buƙatun takardar 0.0015 ″ (38 micron). Ana ba da shawarar yin amfani da faranti mai tsabta na ƙarfe ko aluminium faranti tsakanin laminates.

4. Don taimakawa a cikin lamination, ana yin maganin motsa jiki na minti 20 kafin dumama. Ana kiyaye injin a ko’ina cikin zagayowar. Fitar da iska zai taimaka wajen tabbatar da cewa an tattara kewaye.

5. Sanya thermocouple a cikin yanki na tsakiya na tsakiyar farantin don ƙayyade yawan zafin jiki da kuma sake zagayowar da ya dace.

6. Za’a iya ɗora farantin a kan sanyi ko preheated latsa farantin don farawa. Idan ba a yi amfani da filin matsa lamba don ramawa ba, hawan zafi da wurare dabam dabam zai bambanta. Shigar da zafi zuwa kunshin ba shi da mahimmanci, amma ya kamata a sarrafa shi gwargwadon yadda zai yiwu don rage rata tsakanin yankunan waje da tsakiya. Gabaɗaya, zafin zafi yana tsakanin 12-20oF/min (6-9°C/min) zuwa 425oF (220°C).

7. Da zarar an ɗora a cikin latsawa, ana iya amfani da matsa lamba nan da nan. Har ila yau, matsa lamba zai bambanta tare da girman sashin kulawa. Ya kamata a sarrafa shi a cikin kewayon 100-200psi (7-14bar).

8. Rike zafin zafi mai zafi a 425oF (230°C) na akalla mintuna 15. Dole ne zafin jiki ya wuce 450oF (235°C).

9. A lokacin aikin lamination, rage girman lokacin rashin matsa lamba (kamar lokacin don canja wurin daga latsa mai zafi zuwa latsa mai sanyi). Rike yanayin matsa lamba har sai matsa lamba ya kasa 200oF (100°C).
