Pinhole yog thawj qhov tsis zoo ntawm aluminium ntawv ci. Nyob rau hauv thawj qhov kev kwv yees, yob, dov roj, thiab txawm tias plua plav nplai hauv huab cua nce mus txog 6 μm rau hauv cov yob seam yuav ua rau cov pinholes, yog li 6 μm txhuas ntawv ci tsis muaj pinholes yog tsis yooj yim sua, tsuas yog ntsuas los ntawm ntau npaum li cas thiab ntau npaum li cas. nws loj. Vim yog kev txhim kho ntawm aluminium foil dov tej yam kev mob, tshwj xeeb tshaj yog cov plua plav thiab dov roj muaj txiaj ntsig pom thiab yooj yim yob hloov kev teeb tsa, tus naj npawb ntawm aluminium foil pinholes ntau thiab ntau nyob ntawm qhov zoo ntawm cov khoom siv hlau thiab kev ua haujlwm tsis zoo, vim tias pinholes feem ntau yog cov khoom shortcomings ntawm qhov poob, nws yog ib qho nyuaj rau nrhiav tau tus thawj shortcomings ntawm qhov sib txuas.
Nws yog feem ntau xav tias pinholes feem ntau muaj feem xyuam rau cov ntsiab lus roj, kev deev luag poj luag txiv, kev sib txuas thiab kev sib cais sib cais. Kev siv cov khoom siv txhuas ua kua purification, filtration, grain refinement tuaj yeem pab txo cov pinhole. Ntawm chav kawm, kev xaiv ntawm alloying thiab lwm yam txuj ci los txhim kho cov yam ntxwv hardening ntawm cov khoom kuj yuav pab txo tau pinholes. Cov khoom siv zoo kub dov dov 6μm aluminium foil pinhole tuaj yeem ua rau qis dua 100 / ㎡. Thaum cov khoom cam khwb cia thiab dov tau zoo huv si, cov pinholes ntawm 6μm txhuas ntawv ci yog qis dua 200 / ㎡.
Nyob rau hauv cov txheej txheem aluminium foil dov, lwm cov ntsiab lus uas tsim cov pinholes lossis ntau, txawm tias muaj kev puas tsuaj, ntau txhiab tus pinholes ib square meter tsis yog qhov tsis tshua muaj. Kev pom zoo ntawm cov roj dov, hloov lub sij hawm luv luv ntawm cov yob thiab cov txheej txheem plua plav yog qhov tsim nyog los txo cov aluminium foil pinhole cov xwm txheej, thiab xaiv qhov loj dov quab yuam, me me nro dov kuj tseem yuav pab txo cov pinhole.
