3A21 Ekipande kya Aluminiyamu .

. Amaanyi g’okusika (tensile strength) gali nga 110-160MPa, era okulongoosa ebbugumu tekuyinza kunywezebwa. Obugumu obwa bulijjo buba 0.3-6mm, era embeera egabanyizibwamu O (Soft State), H14/H18 (semi-hard to full hard), etc.

3A21 Aluminium Sheet erina enkola ennungi ennyo ey’okugikyusakyusa era ewagira tekinologiya ow’enjawulo ow’okukola obulungi:

1. Okulongoosa ennyonta .

- Okukuba sitampu: Omugerageranyo gw'okugolola ogusembayo guyinza okutuuka ku 2.3, ogusaanira okukola ebikozesebwa mu ffumbiro, ebidomola n'ebitundu ebirala ebiwanvu ebikuba sitampu

- okubeebalama: radius esinga obutono ey’okubeebalama eri 1.5T (obuwanvu bwa plate), era enkoona y’okuddamu efugirwa mu 2℃.

- Okuwuuta: Obugumu bw’ekisenge Omuwendo omutono oba ogwenkana 70%, ogusaanira okukola ebitundu bya ssiringi .

2. Enkola ey’enjawulo ey’okuweta .

- TIG welding: ER5356 Waya ya welding ekozesebwa, era omugerageranyo gw’amaanyi ga weld gusinga oba gwenkana 0.85 .

- Okuweta kwa layisi: Amaanyi 3-5kW, sipiidi y'okuweta 1.5-3m/min .

- Stir friction welding: naddala esaanira okuyunga ebipande ebinene waggulu wa 6mm .

3. Okukola ebyuma mu ngeri entuufu .

- CNC Okusiba: Sipiidi y’okusala 200-300m/min, obukaluba ku ngulu RA1.6μm .

- Okusima: Sipiidi esengekeddwa 800-1200rpm, Omuwendo gw'emmere 0.1-0.2mm/r

4. Tekinologiya w’okulongoosa kungulu .

- Okulongoosa eddagala: Okukozesa asidi wa phosphoric-Enkola ya asidi wa Nitric, obukaluba bw’okungulu busobola okukendeezebwa okutuuka ku RA0.4μm .

- anodizing: obuwanvu bwa firimu 10-25μm, obukaluba HV300-500 .

- Okukuba omusenyu: Kozesa 120-240 Mesh Glass Sand, SA2.5 Obuyonjo .

5. Enkola y’okulongoosa ebbugumu .

- Annealing: 340-400℃insulation okumala essaawa 2-4 okumalawo ddala okunyigirizibwa kw'okukola .

- Okutebenkeza: 150-180℃insulation okumala essaawa 6 okulongoosa dimensional stability .

1. Esobola okulongoosebwa okusinziira ku byetaago bya bakasitoma;

2. Tekinologiya omukulu ow’okulongoosa, ebbeeyi erina ebirungi bingi bw’ogeraageranya n’abakola koyilo za aluminiyamu abalala;

3. Erina 6 semi-layini ezifulumya ezigenda mu maaso, 10 ezigenda mu maaso n’okusuula n’okuzingulula layini z’okufulumya n’ebyuma ebirala 44 ebinene-ebirongoosa, nga buli mwaka bifulumizibwa ttani obukadde 1.4;

4. Ebifulumizibwa buli mwezi bisobola okutuuka ku ttani 10,000.

Bakasitoma 32 ab’ensi yonna be twakolagana nabo baawadde ekitiibwa ekinene ku 3A21 aluminum plate. Omukozi w'emmeeri y'e Japan yawadde endowooza: "Tewali kukulukuta mu mbeera ya mazzi ga nnyanja okumala emyaka 5, okutuukiriza ebisaanyizo by'okuweebwa ebbaluwa za DNV GL mu bujjuvu." Abakola ebyuma by'eddagala mu Girimaani naddala baategeera omulimu gwayo ogw'okuweta: "Mig welding pass rate yalinnya okuva ku bitundu 85% okutuuka ku bitundu 98%, ekikendeeza nnyo ku nsaasaanya y'okuddamu okukola." Abakola ebyuma by'emmere mu Southeast Asia batendereza nti: "FDA-Ebikozesebwa ebikakasibwa bituukana mu bujjuvu omutindo gw'obuyonjo, era ekikolwa eky'okusiimuula kungulu kisukka 304 ekyuma ekitali kizimbulukuse." 80% ku bakasitoma baawa ebipimo by’emmunyeenye 5 mu kunoonyereza ku kugula, era baali bamativu nnyo naddala: 1) enkyukakyuka z’ebintu eby’ebyuma ebitebenkedde wansi oba okwenkana 3%; 2) okufuga obuwanvu obutuufu (±0.02mm); 3) Zero damage rate y'okupakinga entambula y'ennyanja. Kkampuni ya yinginiya mu Bulaaya emaze emyaka 8 egy’omuddiring’anwa ng’egula, ng’ekuŋŋaanyizza enkozesa ya ttani ezisoba mu 15,000.
