Mfundo Zofunikira Pakupanga Kuwongolera Kwa Matumba Oyikira Maski Amaso

Makulidwe a thumba la filimu:zachilendo 100microns-160microns,makulidwe a chojambula choyera cha aluminiyamu chogwiritsidwa ntchito ndi gulu nthawi zambiri7 microns

Kupanganthawi yotsogolera: akuyembekezeka kukhala pafupifupi masiku 12

Alumiinufilimu:VMPET ndi chinthu chophatikizika chokhazikika chomwe chimapangidwa ndikuyika zitsulo zoonda kwambiri za aluminiyamu yachitsulo pamwamba pa filimu yapulasitiki pogwiritsa ntchito njira yapadera. Ubwino ndi zitsulo luster tingati, koma kuipa ndi osauka chotchinga katundu.

1.Njira Yosindikizira

Malinga ndi zomwe msika ukufunikira komanso momwe ogula amawonera, masks amaso amawonedwa ngati zinthu zapamwamba kwambiri, chifukwa chake zofunikira zodzikongoletsera ndizosiyana ndi zakudya wamba komanso kulongedza kwamankhwala tsiku lililonse, osachepera ndi ogula "okwera kwambiri". psychology. Chifukwa chake posindikiza, kutenga kusindikiza kwa PET monga mwachitsanzo, kulondola kwapang'onopang'ono ndi zofunikira zamtundu wa kusindikiza kwake ndizokwera kwambiri kuposa zomwe zimafunikira pakuyika. Ngati mulingo wadziko ndikuti kulondola kwakukulu kopitilira muyeso ndi 0.2mm, ndiye kuti malo achiwiri osindikizira thumba lachigoba kumaso amayenera kukwaniritsa mulingo wosindikizawu kuti agwirizane ndi zomwe makasitomala amafuna komanso zosowa za ogula.

Pankhani ya kusiyana kwamitundu, makasitomala opaka chigoba kumaso nawonso amakhala okhwima komanso atsatanetsatane kuposa makampani wamba azakudya.

Chifukwa chake, posindikiza, makampani omwe amatulutsa zopaka kumaso ayenera kusamala kuwongolera kusindikiza ndi mtundu. Inde, padzakhalanso zofunikira zapamwamba zosindikizira magawo kuti agwirizane ndi zosindikizira zapamwamba.

2.Lamination ndondomeko

Zophatikizika zimawongolera mbali zazikulu zitatu: makwinya ophatikizika, zotsalira za zosungunulira zamagulu, ma pitting amitundu ndi thovu ndi zina zolakwika. Munjira iyi, zinthu zitatuzi ndizomwe zimakhudzira zokolola zamatumba onyamula chigoba kumaso.

(1) Makwinya ambiri

Monga tikuwonera kuchokera pamwambapa, matumba onyamula chigoba kumaso makamaka amaphatikiza kuphatikiza kwa aluminiyamu yoyera. Aluminiyamu yoyera imakulungidwa kuchokera kuchitsulo choyera kukhala pepala lochepa kwambiri ngati filimu, lomwe limadziwika kuti "filimu ya aluminiyamu" pamsika. Kukula kwake kumakhala pakati pa 6.5 ndi 7 μm. Zoonadi, palinso mafilimu okhuthala kwambiri a aluminiyamu.

Mafilimu opangidwa ndi aluminiyamu amatha kukhala ndi makwinya, kusweka, kapena ma tunnel panthawi yoyatsira. Makamaka laminating makina kuti basi splice zipangizo, chifukwa cha zolakwa mu basi kugwirizana kwa pachimake pepala, n'zosavuta kukhala wosagwirizana, ndipo n'zosavuta kuti filimu zotayidwa makwinya mwachindunji pambuyo lamination, kapena kufa.

Kwa makwinya, kumbali imodzi, tikhoza kuwathetsa pambuyo pa ndondomeko kuti tichepetse zotayika zomwe zimadza chifukwa cha makwinya. Guluu wamagulu akakhazikika ku dziko linalake, kubwezeretsanso ndi njira imodzi, koma iyi ndi njira yokhayo yochepetsera; komano, tingayambire pa chiyambi. Chepetsani kuchuluka kwa mafunde. Ngati mugwiritsa ntchito pachimake chachikulu cha pepala, zomangirazo zimakhala zabwino kwambiri.

(2) Zotsalira za zosungunulira zamagulu

Popeza kuyika kwa chigoba kumaso kumakhala ndi aluminiyamu kapena aluminiyamu yoyera, pazophatikizira, kukhalapo kwa aluminiyamu yoyengedwa kapena yoyera kumawononga kuphulika kwa zosungunulira. Ichi ndi chifukwa chotchinga katundu wa awiriwa ndi amphamvu kuposa zipangizo zina wamba, choncho Zimawononga volatilization wa solvents. Ngakhale zanenedwa momveka bwino mu muyezo wa GB/T10004-2008 "Dry Composite Extrusion Compounding of Plastic Composite Films and Bags for Packaging" muyezo: Muyezo uwu sugwira ntchito ku mafilimu apulasitiki ndi matumba opangidwa ndi zinthu zapulasitiki ndi maziko a mapepala kapena zojambulazo za aluminiyamu.

Komabe, pakadali pano makampani onyamula chigoba kumaso ndi makampani ambiri amagwiritsanso ntchito mulingo wapadziko lonse ngati muyezo. Kwa matumba a aluminiyamu zojambulazo, muyezo uwu umafunikanso, choncho ndi wosocheretsa.

Zoonadi, muyezo wadziko ulibe zofunikira zomveka, komabe tiyenera kulamulira zotsalira zosungunulira pakupanga kwenikweni. Kupatula apo, iyi ndi malo ovuta kwambiri owongolera.

Pazochitikira zaumwini, ndizotheka kupanga kusintha koyenera pakusankha guluu, kuthamanga kwa makina opangira, kutentha kwa uvuni, ndi kuchuluka kwa zida zotulutsa. Zachidziwikire, mbali iyi imafuna kusanthula ndi kukonza zida zapadera komanso malo enaake.

(3) Kubowola kophatikizana ndi thovu

Vutoli limagwirizananso makamaka ndi aluminiyamu yoyera, makamaka ngati ili ndi PET / AL yopangidwa ndi PET / AL, imakhala yowoneka bwino. Pamwamba pake padzakhala "crystal point" - zochitika ngati zochitika, kapena zofanana ndi "bubble" ngati zochitika. Zifukwa zazikulu ndi izi:

Pankhani ya zinthu zoyambira: Kuchiza pamwamba pa zinthu zapansi si zabwino, zomwe zimakonda kuponya ndi thovu; maziko a PE ali ndi mfundo zambiri za kristalo ndipo ndi zazikulu kwambiri, zomwe zimachititsanso mavuto aakulu. Komano, mbali ya tinthu ta inki ndi imodzi mwazinthu. Kusanja kwa guluu ndi tinthu tambiri ta inki kumayambitsanso zovuta zomwezi panthawi yolumikizana.

Kuwonjezera apo, ponena za ntchito ya makina, pamene zosungunulira sizimasungunuka mokwanira ndipo kupanikizika kowonjezereka sikuli kokwanira, zochitika zofanana zidzachitikanso, mwina gluing screen roller imatsekedwa, kapena pali nkhani yachilendo.

Yang'anani mayankho abwino kuchokera pazigawo zomwe zili pamwambazi ndikuweruza kapena kuzichotsa m'njira yomwe mukufuna.

3. Kupanga zikwama

Pamalo olamulira a ndondomeko yotsirizidwa, timayang'ana makamaka ku flatness kwa thumba ndi mphamvu ndi maonekedwe a kusindikiza m'mphepete.

Pakupanga thumba lomalizidwa, kusalala ndi mawonekedwe ndizovuta kumvetsetsa. Chifukwa mulingo wake womaliza waukadaulo umatsimikiziridwa ndi kagwiritsidwe ntchito ka makina, zida, ndi kagwiritsidwe ntchito ka antchito, matumbawa ndi osavuta kukanda panthawi yomaliza, ndipo zolakwika monga zazikulu ndi zazing'ono zimatha kuwoneka.

Kwa matumba a chigoba kumaso ndi zofunikira kwambiri, izi siziloledwa. Kuti tithane ndi vutoli, tithanso kuyang'anira makinawo kuchokera pagawo loyambira la 5S kuti tiwongolere zomwe zikuchitika.

Monga kasamalidwe koyenera ka malo ochitira msonkhano, kuyeretsa makinawo ndi chimodzi mwazinthu zotsimikizira kuti makinawo ndi oyera komanso kuti palibe zinthu zakunja zomwe zimawonekera pamakina kuti zitsimikizire kuti ntchito yabwino komanso yosalala. Inde, tiyenera kusintha zofunika kwambiri ndi zenizeni ntchito zofunika ndi zizolowezi makina.

Pamawonekedwe, potengera zofunikira zosindikizira m'mphepete komanso mphamvu yosindikiza m'mphepete, nthawi zambiri pamafunika kugwiritsa ntchito mpeni wosindikiza wokhala ndi mawonekedwe owoneka bwino kapenanso mpeni wosindikiza wathyathyathya kuti musindikize m'mphepete mwake. Ili ndi pempho lapadera. Ndichiyeso chachikulu kwa ogwiritsa ntchito makina.
