Waa maxay faa'iidooyinka 6μm iyo 6.5μm ee baakadaha cuntada?

1. Gogoldhig: Shuruudaha Muhiimka ah ee Faylasha Aluminiumka ee Baakadaha Cuntada iyo Caqliga Xulashada Dhumucda

Aluminium foil, oo leh hantideeda caqabada ah “eber gudbinta ogsijiinta, qoyaanka, iyo iftiin”, waxay u adeegtaa sidii shay muhiim u ah baakadaha cuntada. Doorkeeda asaasiga ah waxaa ka mid ah dib u dhigista oksaydhka cuntada (E.g., rancidity baruurta), joojinta koritaanka microbial (E.g., faafinta caaryada), iyo ilaalinta isku dhafka dhadhanka (E.g., udgoonka alaabta la dubay)-si toos ah u go'aaminaya nolosha shelf cuntada iyo xasilloonida tayada.

Sida waafaqsan GB/T 31985-2015 Aluminium iyo aluminiumka foils (Heerka Qaranka ee Jamhuuriyadda Dadka Shiinaha), aluminium foil baakadaha cuntada waa inuu buuxiyaa shuruudaha “daahirnimo ≥99.6%, cufnaanta godka ≤5 pcs/m² (Φ≥0.3mm), iyo guuritaanka biraha culus ≤1.0mg/dm²”. Si gaar ah, 6μm iyo 6.5μm hadda waa dhumucyada guud ee Aluminium foil cakinka cuntada warshadaha. Weli, inkastoo farqiga u muuqda inuu yar yahay 0.5μm, Waxqabadkooda kala duwan ayaa diiradda saaraya waxay abuuraan xuduud faa'iido cad: 6μm aluminium foil, la “miisaan yar iyo qiimo jaban”, waxay ku habboon tahay wareegga gaaban, baakadaha awoodda yar; 6.5μm aluminium foil, la “hantida xannibaadda sare iyo xasilloonida sare”, waxay taageertaa wareegga dheer, baakad awood weyn leh. Si aad u furto farqigan, waa lagama maarmaan in la falanqeeyo faa'iidooyinka gaarka ah ee labadaba laga bilaabo saddex dhinac: habka waxqabadka, la qabsiga habaynta, iyo shuruudaha codsiga.

2. Faa'iidooyinka Muhiimka ah ee 6μm Aluminium Foil ee Baakadaha Cuntada: Fudud, Qiimo jaban, iyo La qabsiga Nooca khafiifka ah

Asal ahaan, faa'iidooyinka 6μm Aluminium foil cakinka cuntada asliga ka ah “dabeecadaha nooca khafiifka ah”. Waxay muujinaysaa qiimaha aan la bedeli karin marka la eego xaaladaha ay shuruudaha hantida xannibaadu yihiin kuwo dhexdhexaad ah, iyo xakamaynta kharashka iyo baakadaha fududaynta ayaa mudnaanta la siinayaa:

(1) Faa'iidooyinka Kharashka Fudud iyo Walxaha: Yaraynta Wadarta Baakidhka Culayska iyo Qiimaha Cutubka

The “khafiif ah” Baakadaha cuntadu maaha oo kaliya inay la socdaan isbeddellada deegaanka (yaraynta isticmaalka alaabta) laakiin sidoo kale waxay hoos u dhigtaa kharashaadka saadka (kordhinta mugga gaadiidka mugga cutubkiiba). Gaar ahaan, faa'iidooyinka khafiifka ah ee 6μm Aluminium foil cakinka cuntada waxay ka muuqdaan laba dhinac oo muhiim ah:

1. Cufnaanta aagga hoose: Cufnaanta aagga 6μm foil aluminiumku waa qiyaastii 16.2g/m² (cufnaanta aluminium: 2.7g/cm³), taas oo ah 7.7% ka hooseeya 6.5μm (17.55g / m²). Tusaale ahaan, qaadashada wax soo saarka sanadlaha ah ee 100 malyuun m² oo baakad cunto ah tusaale ahaan, 6μm Aluminium foil cakinka cuntada wuxuu yarayn karaa isticmaalka maaddada 13.5 tan, si toos ah u dhimaya kharashyada alaabta ceeriin qiyaastii 270,000 RMB (ku salaysan qiimaha bireed aluminium ah 20,000 RMB/ton);

2. Wadarta guud ee miisaanka baakooyinka hoose: Cuntooyinka awoodda yar (E.g., 10-50g nuts, 20ml suugo xawaash ah), miisaanka guud ee baakadaha laga sameeyey 6μm bireed aluminium waa 5%-8% ka hooseeya 6.5μm. Tani waxay buuxinaysaa baahida kor u qaadista kharashka ee saadka e-ganacsiga ee loogu talagalay “baakadaha fudud iyo kuwa yaryar”-Tusaale ahaan, dhimista miisaanka qof kasta 1,000 xirmooyinka 1kg waxay hoos u dhigi karaan kharashka gaadiidka sannadlaha ah by 3%-5%.

(2) Geedi socodka Nooca khafiifka ah ee heer sare ah: Laqabsiga Shuruudaha Samaynta Kakan iyo Lamination

Ka baxsan faa'iidooyinka kharashka, 6μm Aluminium foil cakinka cuntada sidoo kale waxay aad ugu fiican tahay habaynta la qabsiga - arrin muhiim u ah baakadaha cuntada, kuwaas oo inta badan loo maro habab adag sida “gees isku laabma, kicinaya, iyo kuleylka kuleylka”. Sababo la xiriira dhumucdeeda dhuuban iyo dabacsanaanteeda sare, xaashidaani waxay bixisaa laba faa'iidooyin farsamaynta muhiimka ah:

1. Saxnaanta samaynta sare: Gudaha “baakad gaar ah oo qaabaysan” (E.g., baakadaha shukulaatada saddex xagal ah, bacaha yaryar ee qaxwada degdega ah), radius foorarsiga ugu yar ee 6μm bireed aluminium gaari karaa 0.5mm (marka loo eego ≥1mm ee 6.5μm). Ka dib markii la sameeyo, Ma jiro “laablaabashada”, iyo flatness dusha baakadaha waxaa lagu hagaajiyay by 20%;

2. Waxqabadka lamination substrate wanaagsan: Marka lagu daro filimaan balaastik ah (E.g., Xayawaan dab-joog, PE PE), 6μm Aluminium foil cakinka cuntada wuxuu leeyahay lebbis dhumucdiisu sareeyso (dulqaad ≤±5%), taasoo keentay kala fogaansho lamination leh substrate-ka ≤1μm (vs. qiyaastii 1.5μm ee 6.5μm). Maya “xumbo” foomka ka dib lamination, iyo xoogga kuleylku wuxuu gaarayaa 45N/15mm (vs. 42N/15mm ee 6.5μm), buuxinta shuruudaha xidhitaanka ee maaraynta soo noqnoqda sare.

(3) La qabsiga Codsiga: Doorashada Dhaqaale ee Nolosha-Shalf-Gaaban, Cuntooyinka Awoodda Yar

Si ficil ahaan loo hadlo, inkastoo hantida caqabadda ah ee 6μm Aluminium foil cakinka cuntada (heerka gudbinta ogsijiinta: 0.3-0.5cm³/(m² 24h · atm); heerka gudbinta uumiga biyaha: 0.1-0.2g/(m² · 24h)) wuxuu ka hooseeyaa 6.5μm, waxay si buuxda u daboolaysaa baahiyaha cuntooyinka nolosha-gaaban. Xaaladaha caadiga ah ee lagu dabaqi karo waxaa ka mid ah cuntooyinka fudud ee awoodda yar, Cunno cusub oo la jarjaray oo diyaar u ah in la cuno, iyo baakadaha xawaash ee la tuuri karo-kuwaas oo dhan ka hormari waxtarka kharashka marka loo eego xasilloonida caqabadaha muddada-dheer, Caawinta ganacsiyada isu dheelitirka kharashyada iyo shuruudaha ilaalinta aasaasiga ah.

3. Faa'iidooyinka Muhiimka ah ee 6.5μm Aluminium Foil ee Baakadaha Cuntada: Hantida Barrier Sare, Degenaansho Sare, iyo Ilaalinta Joogtada Dheer

Si ka duwan 6μm foil, 6.5μm Aluminium foil cakinka cuntada Ahmiyada “shaqo ka dhimis”. Waxay muujinaysaa faa'iidooyinka muhiimka ah ee wareegga dheer, Baakadaha cuntada ee awoodda weyn leh halkaasoo shuruudo adag lagu soo rogay hantida xannibaadda, Xoogga makaanikada, iyo iska caabinta cimilada:
