Iwo maburi madiki asina kujairika anoonekwa kuchiedza pamusoro pearuminiyamu foil anonzi pinholes. Sezvo ukobvu hunoderera, nhamba yepinholes inowedzera, inova imwe yezvakanyanya kukanganisa kwefoil zvinhu.

Hupfu mubillet, pamupumburu, mumafuta ekuzora, uye kunyange mumhepo inosvika saizi inenge 6 μm uye inopinda mupumburu, izvo zvichaita kuti pinholes. Naizvozvo, hazvigoneke 65m aluminium foil kusava nemapinhole. Inogona kuongororwa chete nehuwandu uye saizi.

Nekuvandudzwa kweiyo yakaiswa simba realuminium foil michina, mamiriro ealuminium foil rolling anovandudzwa, kunyanya kusefa kunoshanda kwekudzivirira guruva uye mafuta anotenderedza uye kuseta kwekukurumidza roll shanduko system, kuitira kuti nhamba uye saizi yepinholes mubhokisi realuminium iri kuwedzera kutsamira paIyo metallurgical quality uye machining defects yebillet..

Sezvo buri repini rinowanzoteura chirema chisina chinhu, zvakaoma kuwana hukama hunoenderana nehurema hwepakutanga. Zvinowanzotendwa kuti pinholes inonyanya kuenderana negasi ririmo, inclusions, mubatanidzwa uye kupatsanurwa kwechikamu.

Kutora inoshanda aluminium mvura yekuchenesa, kusefa, uye kunatswa kwezviyo kunogona kubatsira kuderedza pinholes.

Kuvandudza kuoma kwezvinhu zvezvinhu, sekunge alloying, inogonawo kubatsira kuderedza pinholes. Mapinhole e6μm aruminiyamu foil akakungurutswa nearuminiyamu mapini emhando yepamusoro anogona kuve asingasviki 100/m².. Mune aluminium foil rolling process, pane zvimwe zvakawanda zvinokonzeresa mapinholes, izvo zvinogona kuva njodzi. Zviuru zvepinholes pa square mita hazvina kujairika. Simbisa kusefa kwemafuta anotenderedza.

Yenguva pfupi yekutsiviwa kwema rolls uye guruva-proof matanho mamiriro anodiwa ekudzikisa mapinho mualuminium foil; kushandisa simba guru rekukungurutsa uye diki tension rolling zvichabatsirawo kuderedza pinholes.
