Foil aluminium dawo pinhole iyo soo saarista: Aluminium birta waxay leedahay qaab-dhismeedka biraha cufan oo aad u cufan, iyo foil aluminium sifiican oo aluminium ah ayaa gebi ahaanba xannibi kara gaas kasta, uumiga biyaha iyo iftiinka. Laakiin dhab ahaantii, Sababo la xiriira saamaynta arrimo badan oo ay ka mid yihiin geedi socodka isdhaafsiga ee loo isticmaalo soo saarista foinium aluminium, tayada saliida duudduuban, Xaaladda dusha sare ee liiska duudduuban, Teknolojiyadda Howlgalka Nidaamka Howlgalka iyo Deegaanka Goobta Soosaarka, Cillad kala duwan oo aan macquul ahayn ayaa ka muuqda fash aluminium, Gaar ahaan fashtanka aluminium khafiifka ah. Pinholes waa mid ka mid ah kuwa ugu muhiimsan.

Cabbirka iyo tirada pisholes waa mid ka mid ah miraha muhiimka ah ee lagu cabiro heerka tayada ee alaabada aluminium. Waa wax sax ah sababta oo ah jiritaanka guntin oo ku saabsan in la halmayo oksijiinka iyo uumiga biyuhu ay u egtahay aluminium-ka ma aha eber.

Cabbirka iyo tirada tirooyinka aluminiumka waxay leeyihiin saameyn muhiim ah caabbinta qoyaan, Guryaha xasaasiga gaaska iyo guryaha iftiinka iftiinka ee foil aluminium iyo agabkeeda. Dalkayga Qaranka ee dalka GB3198-1996 wuxuu ka dhigayaa qodobada soosocda ee ku saabsan pinholes: “Dusha sare ee foil aluminium waxaa loo oggol yahay in lagu muujiyo in indhaha oo qaawan, Laakiin pinates-ka lama qabanqaabin doono, dhexroorna ku dhaca fashilka aluminium ee daawada ma ka weynaan doono 0.3 mm, oo waa inaanad ka badnaan doonin 0.3 mm. 5 PCS / M². Cabbirka Pinhole ee banigooyinka kale ee aluminium ee kale ma dhaafi doono 0.5 mm.

Maxaa yeelay pinholes-ka waa tilmaame muhiim u ah ogaanshaha aluminium aluminium, Qalabyo farsamo oo badan oo ajnabi ah ayaa qeexaya finanka aluminium foils aluminium ama ubusha uumiga biyaha ee uumiga aluminium. Bulshada Mareykanka ee Imtixaanka iyo Qalabka Qalabka AstMB-479-85 “Heerka farsamada ee loo yaqaan 'aluminium aluminium' iyo aluminium aluminium baakadaha loo yaqaan 'clouming'” caddayn: “Waa inaanu jirin jeexan aad u badan, iyo foil aluminium leh dhumuc weyn 0.5 mm waa inuu ka madax banaanaadaa weelka.” Heerka Warshadaha Jabbaan Jisz1520 -1975 “Halbeega loogu talagalay aluminite aluminium” Waxay siisaa xogta uumiga uumiga biyaha ee uumiga.

Hadda, Waxaa jira farqi weyn oo u dhexeeya heerka tayada ee foil aluminium iyo wadamada shisheeye, kaas oo inta badan lagu muujiyo tirada iyo cabirka guntiga. Qaar ka mid ah heerarka shisheeye qaarkood ayaa qeexaya in aysan jirin wax lagu dhejiyo markii dhumucda aluminium ay ka weyn tahay 0.025 mm, In kasta oo heerarka guryaha lagu qeexayo in aysan jirin inhole markii dhumucda foil aluminium uu ka weyn yahay 0.05 mm. Loogu talagalay pinholes, heerarka shisheeye waxay ku dhisan yihiin in pinholes ka weyn kan 0.1 mm lama oggola, In kasta oo heerarka guryuhu ay qeexeen in cabirka ugu badan ee pinholes uu gaari karo 0.5 mm.

Hagaajinta tayada foimuunka aluminiumka iyo yareynta tirada iyo cabirka ku-dhejiska ee foil aluminium waa dhibaatooyinka ah in fashilka aluminium-ka ay u baahan yihiin xalinta. HWPFP waxay had iyo jeer ku daadatay dadaalkan si loo hubiyo tayada fouminamka aluminium daawo.

Kormeerka shahaadada Pinhole ee faasho aluminium-ka daawada ee lagu dhammeeyay: Miiska kormeerka Pinhole: Adeegso sanduuq alwaax ah oo ah 800 mm x 600 mm x 300 mm ama mugga ku habboon, Ku rakib laambad 30w ah oo ku yaallay sanduuqa alwaax, Ku dheji saxan muraayad ah sanduuqa alwaax, iyo saxanka muraayadda waxaa lagu dhejiyaa warqad madow oo ka tanaasulo 400mm x 250mm ah oo loogu talagalay kormeerka muuqaalka muunadaha. Gelid 20 Muunado dherer ah 400 mm iyo ballac 250 mm laga soo bilaabo foil aluminium dhammaadka, Ku dheji miiska kormeerka Pinhole mid mid mid mid ah, oo hubi tindhadooda mugdiga ah.

Shuruudaha loo yaqaan 'pinholes' waa in aysan jirin cufan, soconeya, Jinsiyada xilliyeed, Ma jiro muunado oo dhexroor ka weyn 0.3 mm, oo aan ka badnayn 1 Pinhole halkii mitir labajibbaaran oo leh dhexroor ah 0.1-0.3 mm .
