Thaum xaiv cov hnab ntim khoom kub, cov khoom nyiam yog aluminium ntawv ci. Yog li vim li cas thiaj li siv tau cov hnab aluminium ntawv ci los ua cov hnab ua noj kub kub? Kab lus no yuav txheeb xyuas kom meej txog cov yam ntxwv ntawm cov hnab ntawv aluminium raws li cov hnab ntim khoom noj kub kub.
1. Aluminium ntawv ci hnab muaj kev sib khi zoo thiab muaj zog thaiv cov khoom. Aluminium ntawv yuav tsum muaj tsawg dua pinholes. Txawm li cas los xij, yog tias nws muaj pinholes, nws cov khoom thaiv yuav raug txo kom tsawg, roj thiab lub teeb yuav nkag mus ncaj qha, thiab cov ntsiab lus yuav sai sai. Feem ntau hais lus, qhov tuab ntawm aluminium ntawv ci, qhov tsawg dua tus pinholes. Piv txwv li, tus naj npawb ntawm pinholes rau 7μm tuab aluminium ntawv yuav tsum tsawg dua 200 qhov / square meter: tus naj npawb ntawm pinholes rau 9μm tuab txhuas ntawv ci yuav tsum tsawg dua 100 qhov / square meter. square meters. Txawm tias tuab npaum li cas ntawm cov ntawv txhuas txhuas yog, lub pinhole txoj kab uas hla yuav tsum tsis txhob loj dua 20 μm.
2. Cov hnab ci aluminium yog cov khoom noj muaj kev nyab xeeb-kev nyab xeeb, tsis muaj roj thiab hmoov av, thiab cov roj siab, thiab cov dej siab dua 72mn / m. Ib txoj hauv kev yooj yim yog siv cov dej distilled los xyuas. Cov dej distilled yuav tsum ua kom moisten saum npoo ntawm aluminium ntawv ci. Yog tias qhov saum npoo ntawm aluminium ntawv ci yog oily tiag tiag, nws yuav cuam tshuam rau kev sib xyaw ceev ntawm aluminium ntawv ci thiab lwm yam ntaub ntawv. Tshwj xeeb tshaj yog tom qab lub hnab ntim tau siav ntawm qhov kub thiab txias, delamination yuav tshwm sim.
3. Cov khoom siv aluminium ntawv yog mos, yooj yim rau tawg, thiab yuav tsum muaj zoo toughness. Cov ntawv txhuas uas tau yuav yuav tsum tau khaws cia rau hauv lub xeev qhuav thiab yuav tsum tsis txhob cia ntev dhau. Nws yuav tsum tau siv sai li sai tau los tiv thaiv cov ntawv txhuas los ntawm absorbing noo noo thiab oxidizing thiab deteriorating.
Aluminium ntawv ci yog hlau. Mos aluminium ntawv ci nrog lub thickness ntawm 9 μm (7 μm tuab kuj siv tau) feem ntau yog siv rau hauv cov hnab ntim khoom noj. Nws muaj kev tiv thaiv zoo noo noo, roj barrier thiab lub teeb barrier zog. Yog tias tsis muaj kev puas tsuaj thiab cov pinholes, nws yog impermeable rau cov dej noo, huab cua, thiab lub teeb, thiab muaj qhov kub thiab txias tsis kam thiab roj tsis kam. Yog li ntawd, lub hnab ntim khoom sib xyaw uas muaj cov ntawv txhuas muaj lub luag haujlwm ntawm kev sib khi tag nrho, muaj ntxhiab tsw qab, muaj roj ua haujlwm siab, thiab kub tsis kam.
