Lub ntsiab tsis xws luag ntawm aluminium foil jumbo yob yog:
Feb 10, 2022
Lub ntsiab tsis xws luag ntawm aluminium foil jumbo yob yog:
(1) Pinhole. Pinholes yog qhov tsis xws luag ntawm txhuas ntawv ci jumbo yob. Hauv cov khoom siv raw, ntawm yob, hauv cov roj dov, thiab txawm tias cov plua plav hauv huab cua ncav cuag li 6μm thiab nkag mus rau qhov sib txawv ntawm qhov yob, nws yuav ua rau cov pinholes. Yog li ntawd, nws yog tsis yooj yim sua rau 6μm txhuas ntawv ci jumbo yob kom tsis muaj pinholes. Nws tsuas yog ntsuas los ntawm ntau npaum li cas thiab nws qhov loj. Vim yog kev txhim kho ntawm txhuas ntawv ci jumbo yob dov tej yam kev mob, tshwj xeeb tshaj yog cov zoo filtration ntawm plua plav thiab dov roj thiab qhov chaw ntawm yooj yim yob hloov system, tus naj npawb ntawm pinholes nyob rau hauv txhuas ntawv ci jumbo yob yog ntau thiab ntau nyob ntawm seb metallurgical zoo ntawm raw. cov ntaub ntawv thiab kev ua tsis raug. Nws yog qhov nyuaj los nrhiav kev sib raug zoo nrog cov khoom qub thaum qhov tsis xws luag ntawm cov khoom siv poob. Nws feem ntau ntseeg tias pinholes feem ntau cuam tshuam nrog cov ntsiab lus roj, suav nrog, cov khoom sib txuas thiab kev sib cais sib cais. Ua tau zoo txhuas cov kua purification, pom, thiab lis refinement tuaj yeem pab txo cov pinholes. Tau kawg, kev siv cov alloying thiab lwm yam txhais tau tias los txhim kho cov yam ntxwv hardening ntawm cov khoom kuj pab txo cov pinholes. Lub pinholes ntawm 6μm txhuas ntawv ci jumbo yob dov los ntawm cov ntaub ntawv zoo kub dov tuaj yeem tsawg dua 100 / ㎡. Thaum cov ntaub ntawv casting thiab dov tau zoo huv si, lub pinholes ntawm 6μm txhuas ntawv ci jumbo yob yog qis dua 200 / ㎡. Nyob rau hauv cov txheej txheem aluminium ntawv jumbo yob dov, muaj ntau lwm yam uas ua rau cov pinholes, txawm tias muaj kev puas tsuaj, thiab ntau txhiab tus pinholes ib square meter tsis tshua muaj. Kev pom zoo ntawm cov roj dov, hloov lub sij hawm luv luv ntawm cov yob thiab cov kev ntsuas plua plav yog txhua yam tsim nyog los txo cov pinholes hauv aluminium ntawv ci jumbo yob, thiab kev siv lub zog loj dov thiab me me nro dov yuav pab txo cov pinholes.
(2) Roll mark, yob qhov muag, tsis sib xws gloss. Nws yog qhov tseem ceeb ntawm aluminium ntawv ci jumbo yob qhov tsis xws luag tshwm sim los ntawm yob, uas tau muab faib ua peb hom: taw tes, kab thiab nto. Qhov tseem ceeb tshaj plaws tshwm sim nyob rau hauv peb lub voj voog. Cov laj thawj tseem ceeb rau qhov tsis xws luag yog: kev sib tsoo ntawm cov yob tsis raug; kev puas tsuaj rau cov yob los ntawm cov khoom txawv teb chaws: tuaj tsis xws luag imprinting cov yob; yob qaug zog; kev cuam tshuam ntawm yob, slippage, thiab lwm yam. Txhua yam uas tuaj yeem ua rau kev puas tsuaj rau saum npoo ntawm yob tuaj yeem ua rau muaj kev puas tsuaj rau cov yob ntawm aluminium ntawv ci jumbo yob. Vim tias qhov chaw ua tiav ntawm cov ntawv ci aluminium jumbo yob yob yob yog siab heev, me ntsis gloss yuav cuam tshuam rau nws qhov chaw. Kev tu lub tshuab dov tsis tu ncua, ua kom lub tshuab dov huv si, ua kom lub cev ua haujlwm ntawm cov yob huv si, hloov yob tsis tu ncua, thiab kev sib tsoo tsim nyog yog cov txheej txheem yooj yim los xyuas kom meej qhov sib xws ntawm aluminium ntawv ci jumbo yob tom qab dov.
