1060 Koyilo ya Aluminiyamu .

1060 Aluminiyamu coil ye coil ya aluminiyamu eya waggulu-Purity Industrial Aluminium nga erimu aluminiyamu esukka mu 99.6%. Ekozesebwa nnyo mu kukola ebitundu n’ebintu eby’okwewunda ebiteetaaga maanyi ga waggulu olw’okutondebwa obulungi, okuweta n’okuziyiza okukulukuta. Esaanira ebipande, ebyuma by’omu nnyumba, amakolero agapakira n’okuzimba. Olw’obuzito bwayo obutono n’okugirongoosa mu ngeri ennyangu, kifuuse ekintu ekisinga okwettanirwa mu bintu bingi eby’amakolero ebitangaavu.

I. Ebifaananyi ebikulu .

Ebikozesebwa mu kukola ebintu .

Ebirungo bya aluminiyamu ebisinga oba byenkana 99.6%, nga obucaafu (nga Fe ne Si) bufugibwa nnyo mu 0.4%, ekifuula amakolero amalongoofu -Purity industrial-grade aluminiyamu.

Nga erina density ya 2.71 g/cm3, egatta ductility etali ya buzito ate nga nnungi nnyo.

Ebintu ebirabika .

Obutambuzi bwayo obw’amasannyalaze buba bwa kubiri ku ffeeza n’ekikomo, era obutambuzi bwayo obw’ebbugumu buba butono oba bwenkana 2 W/(m・K), ekigifuula esaanira okukozesebwa okusaasaanya amasannyalaze n’ebbugumu.

Firimu ya dense oxide enyangu okukola ku ngulu, egaba okuziyiza okulungi ennyo okw’okukulukuta.

Ebintu eby'okukanika .

Amaanyi g’okusika aga 75-136 MPa n’okuwanvuwa kwa 3%-20%, ekigifuula esaanira okukuba sitampu, okukuba ebifaananyi, n’enkola endala.

II. Enkola y’okufulumya .

Okulongoosa ebintu ebisookerwako .

High-Obulongoofu Aluminiyamu Ingots zisaanuusibwa okuggyawo obucaafu n’okukakasa ekirungo ekimu.

Enkola y’okuyiringisibwa .

Okuyiringisibwa okw’ebbugumu n’okuyiringisibwa okw’ennyogoga byegattira wamu ne bifuga obuwanvu (0.01-300mm). Annealing oluvanyuma lw’okuyiringisibwa ennyogovu etereeza obukaluba (O/H14/H24, n’ebirala).

Okulongoosa kungulu .

Anodizing, painting, embossing, n’enkola endala ziriwo okutumbula eby’okwewunda oba ebikola.

iii. Okusaba okukulu .

Okuyooyoota mu by'okuzimba .

Ebisenge bya kateni ne siringi (0.8-1.5mm obuwanvu), okufuuyira fluorocarbon okumala emyaka 20 egy’okuziyiza embeera y’obudde.

Ebyuma ebikozesebwa mu byuma n’amasannyalaze .

Radiator base (0.1-0.3mm ultra-thin aluminiyamu coil), busbars ezitambuza.

Okupakinga n'amakolero .

Emmere ya aluminiyamu (0.006-0.2mm), payipu insulation aluminum sheet (0.3-0.6mm).

iv. Ekitabo ekilungamya okugula .

Ebikwata ku nsonga .

Obugumu n’obugazi birina okukwatagana n’enkozesa egenderere (okugeza, ebbakuli enzito ey’okuzimba, ultra-egonvu ku kipande okupakinga).

Embeera y’okungulu .

Endabirwamu, endabirwamu, oba ebifaananyi ebikoleddwa mu ngeri ey’ekika kya embossed (nga ebifaananyi eby’ekika kya orange peel oba dayimanda) bikosa anti-okuseerera n’okuyooyoota.

Okulonda omugabi .

Okusinga londa abagaba ebintu abawa obuweereza obw’enjawulo nga slitting ne annealing.

1060 Aluminium coil, olw’obulongoofu bwayo obw’amaanyi n’obwangu bw’okulongoosa, ssente-Okulonda okulungi eri amakolero nga okuzimba n’ebyuma eby’amasannyalaze.

1. Okwoza ebyuma (okusaanira okusobola okukola amangu, ku-Okulongoosa mu kifo) .

Sandpaper/wire brush polishing .

Kozesa 400-600 grit sandpaper oba brush ya waya ennungi (φ less than or equal to 0.2mm) okusiimuula ekitundu kya weld (mu 30-50mm of the edge) mu ngeri emu, okwewala okusalasala okusalako.

Weld amangu ddala nga omaze okujjanjabwa okuziyiza secondary oxidation.

Okukuba omusenyu .

Okukozesa okukuba ebituli mu ndabirwamu oba omusenyu gwa quartz mu bwangu kiyinza okuggyawo kyenkanyi firimu ya oxide n’okwongera ku bukaluba bw’okungulu, okulongoosa okunyweza kwa solder.

2. Okwoza eddagala (ekisaanira okulongoosebwa mu ngeri entuufu oba ey’ekitundu) .

Enkola y'okusiika .

Nnyika mu nitric acid solution (30%-50% concentration) okumala eddakiika 3-5 okusaanuusa firimu ya aluminium oxide. Oyoze n’amazzi agookya (60-70℃) okumalawo asidi yenna asigaddewo.

Dilute hydrochloric acid oba sodium hydroxide solution nayo esobola okukozesebwa okuggyawo amphoteric reaction ya aluminium oxide.

Alkaline Okuggya Amasavu .

Nnyika mu sodium hydroxide solution (40%-50%) okubuguma okutuuka ku 60-70℃okumala eddakiika 5-8 okuggyawo omulundi gumu amafuta ne oxide layer.

3. Obukodyo bw’okukola ku welding mu kiseera kye kimu .

INERT GAS Okukuuma omukka .

Kozesa high-obulongoofu argon ( obusinga oba obwenkana 99.99%) mu kiseera kya argon arc welding okwawula empewo n’okuziyiza firimu ya oxide okuddamu okukola.

Obuyambi bwa Flux obw'enjawulo .

Okugeza, M51-F flux (Ebbugumu erikola 179-200℃) esobola okumenyawo firimu ya oxide n’okutumbula okutambula kwa solder, naye ebbugumu lirina okufugibwa ennyo okutuuka ku litono oba okwenkana 250℃.

4. Okwegendereza .

Oluvannyuma lw’okuyonja eddagala, naaba bulungi okuziyiza ebirungo ebisigaddewo okuvunda ekintu ekikulu.

Omulimu gw’okungulu guli waggulu oluvannyuma lw’okuyonja ebyuma, kale kirungi okumaliriza welding mu ssaawa 2.

Okugatta enkola ezo waggulu kisobola bulungi okugonjoola ekizibu kya firimu ya oxide nga tuweta 1060 aluminium plates.

I. Emirimu emikulu n’emisingi gy’okusunsulamu egya flux .

Flux okusinga ekozesebwa okuggya firimu za okisayidi ku byuma, okulongoosa solder wettability, n’okukuuma ekyuma ekisaanuuse obutafuuka bucaafu. Okulowooza okujjuvu kulina okukolebwa nga olondawo flux:

Ekika ky'ekyuma .

Ku bintu ebirina solderability ennungi (nga copper ne tin): rosin oba rosin alcohol solutions ze zisinga okwettanirwa, kuba tezikola nnyo era zireka residue enyangu okuyonjebwa.

Ku bintu ebirina solderabiliki embi (nga ekyuma ekitali kizimbulukuse n’ekikomo): ebiwujjo ebitaliimu oba asidi (nga zinki chloride-tabricles za ammonium chloride) byetaagibwa, naye beera n’ebirowoozo ku mpisa zaabyo ezikosa.

Welding Environment Ebyetaago .

Ku circuit soldering electronic: Weewale fluxes ezirimu halides (nga inorganic fluxes) okuziyiza component corrosion.

Ku bitundu by’enzimba ebya waggulu-: Kozesa ebiwujjo bya alkaline ebingi (nga okuweta kwa arc mu mazzi) okulongoosa obugumu bwa weld.

II. Ebika bya Flux ebya bulijjo n'okukozesebwa .

rosin-ebiwujjo ebisinziira ku .

Non-Activated Rosin: Esaanira okusoda mu ngeri ya precision electronic, esigaza ebisigadde bitono naye nga erina eby’okwoza ebibi. Activated Rosin (RMA): Erimu Acid Activator enafu okusobola okuyonja ennyo, naye yeetaaga okuyonja okuggyawo ebisigadde.

Resin/Ekikulukuto ky’okusengejja .

Enywevu nnyo, efulumya ebisigadde ebitono, ekigifuula esaanira okusoda mu ngeri ey’otoma (nga enkola za SMT).

Asidi Flux .

Ekizimbulukusa eky’awaka: Omunnyo, asidi wa citric, n’amazzi (okuweta ekyuma ekitali kizimbulukuse) oba ekyuma ekiyonja kaabuyonjo (eky’okuddako eky’ekiseera).

Okulabula ku bulabe: Okukosa ennyo, kyetaagisa okuyonja obulungi oluvannyuma lw’okusoda.

iii. Obukodyo bw’okukozesa flux n’okwegendereza .

Enkola z’okukozesa .

Ku lw’okusoda mu kitundu ekitono-Kozesa ekkalaamu oba ppamba okusobola okusiiga obulungi.

Ku batch soldering: Kozesa liquid flux ne brush, okufuga omuwendo ogukozesebwa okwewala obucaafu.

Obukuumi n’okukuuma obutonde bw’ensi .

Weewale okussa omukka (naddala ng’okozesa asidi) n’okukakasa ekifo w’okolera.

Amazzi-Solumble flux gasinga kukola ku butonde, naye yeetaaga enkola y’okuyonja.

Nga okwataganya ebyuma n’ebyetaago by’enkola, omutindo gw’okusoda n’obulungi bisobola okulongoosebwa ennyo.
