filimu yotambasula ya pallet yonyamula

Filimu yotambasula, yomwe imadziwikanso kuti filimu yotambasula ndi filimu yochepetsera kutentha, ndiyo yoyamba ku China kupanga filimu yotambasula ya PVC yokhala ndi PVC ngati zinthu zoyambira ndi DOA ngati pulasitiki komanso zomatira zokha. Chifukwa cha chitetezo cha chilengedwe, mtengo wokwera (poyerekeza ndi kuchuluka kwa PE, malo ochepa olongedza katundu), kusakhoza kutambasula bwino, ndi zina zotero, zinathetsedwa pang'onopang'ono pamene kupanga filimu ya PE kutambasula kunayambika kuyambira 1994 mpaka 1995. Tambasulani filimu yoyamba imagwiritsa ntchito EVA ngati zinthu zodzikongoletsera, koma mtengo wake ndi wokwera ndipo uli ndi kukoma. Pambuyo pake, PIB ndi VLDPE zimagwiritsidwa ntchito ngati zomatira zokha, ndipo maziko ake ndi LLDPE. Filimu yotambasula ikhoza kugawidwa mu: filimu yotambasula ya PE, filimu yotambasula ya PE, filimu yotambasula ya LLDPE, filimu yotambasula ya PE, ndi zina zotero. Itha kupanga filimu yotambasulira yambiri yogwiritsidwa ntchito pamanja, kugwiritsa ntchito makina amtundu wokana, kugwiritsa ntchito makina amtundu wa pre-stretch, anti-ultraviolet, anti-static and anti- dzimbiri. Lili ndi ubwino wotsatirawu: Pogwiritsa ntchito zida zopangira ma co-extrusion awiri-wosanjikiza, filimu yoponderezedwa yotambasulira imatha kukulitsa mawonekedwe a polima iliyonse, ndipo kuwonekera kwake, kulimba kwamphamvu, komanso kukana kwa perforation ndikwabwino kwambiri ikafika posungunuka. udindo. 2. Ili ndi luso lotambasula bwino, kuwonekera bwino komanso makulidwe ofanana. 3. Ili ndi kutalika kwautali, kulimba mtima, kukana kung'ambika bwino, komanso zomatira zabwino kwambiri. 4. Ndi zinthu zachilengedwe komanso zobwezeretsedwanso, zopanda pake, zopanda poizoni, ndipo zimatha kuyika chakudya mwachindunji. 5. Ikhoza kupanga mankhwala a viscous a mbali imodzi, kuchepetsa phokoso lomwe limatuluka panthawi yokhotakhota ndi kutambasula, ndi kuchepetsa fumbi ndi mchenga panthawi yoyendetsa ndi kusunga. 1. Zosindikizidwa zosindikizidwa Mtundu woterewu ndi wofanana ndi kutsitsa filimu. Kanemayo amakulunga thireyi mozungulira thireyi, ndiyeno zotengera ziwiri zotenthetsera kutentha zimasindikiza filimuyo mbali zonse ziwiri. Iyi ndiyo njira yoyamba yogwiritsira ntchito filimu yotambasula, ndipo mafomu opangira zowonjezera apangidwa kuchokera ku 2. Kupaka m'lifupi mwake Kuyika kwamtundu woterewu kumafuna kuti filimuyi ikhale yochuluka mokwanira kuti iphimbe phallet, ndipo mawonekedwe a pallet ndi nthawi zonse, choncho ili ndi zake, zoyenera filimu makulidwe a 17～35μm 3. Kupaka pamanja Mtundu uwu wa ma CD ndi mtundu wosavuta kwambiri wa filimu yotambasula. Firimuyi imayikidwa pazitsulo kapena m'manja, ndipo thireyi imazungulira kapena filimuyo imazungulira thireyi. Izo makamaka ntchito repackaging pambuyo atakulungidwa mphasa kuonongeka, ndi wamba mphasa ma CD. Kuthamanga kwamtunduwu kumachedwa, ndipo makulidwe oyenera a filimu ndi 15-20μm; 4. Tambasula filimu kukulunga makina ma CD Iyi ndi njira yodziwika kwambiri komanso yotakata yoyika makina. Tereyi imazungulira kapena filimuyo imazungulira mozungulira thireyi. Filimuyo imayikidwa pa bulaketi ndipo imatha kusuntha mmwamba ndi pansi. Kupaka kwamtunduwu ndi kwakukulu kwambiri, pafupifupi ma tray 15-18 pa ola limodzi. Makulidwe oyenera a filimu ndi pafupifupi 15-25μm; 5. Yopingasa makina ma CD Zosiyana ndi ma CD ena, filimuyo imazungulira katundu, oyenera kulongedza katundu wautali, monga makapeti, matabwa, fiberboards, zooneka zipangizo, etc.; 6. Kupaka machubu a mapepala Ichi ndi chimodzi mwazogwiritsira ntchito filimu yotambasula, yomwe ili yabwino kusiyana ndi mapepala akale a mapepala. Makulidwe oyenera a filimu ndi 30～120μm; 7. Kupaka zinthu zing'onozing'ono Ichi ndi mawonekedwe atsopano opangira mafilimu otambasula, omwe sangachepetse kugwiritsira ntchito zinthu, komanso kuchepetsa malo osungiramo mapepala. M'mayiko akunja, mtundu uwu wa ma CD unayambitsidwa koyamba mu 1984. Chaka chimodzi chokha pambuyo pake, zambiri zoterezi zinawonekera pamsika. Mapaketi awa ali ndi kuthekera kwakukulu. Oyenera filimu makulidwe a 15～30μm; 8. Kuyika kwa machubu ndi zingwe Ichi ndi chitsanzo cha kugwiritsa ntchito filimu yotambasula m'munda wapadera. Zida zonyamula katundu zimayikidwa kumapeto kwa mzere wopanga. Kanema wotambasulira wodziwikiratu sangangolowetsa tepiyo kuti amange zinthuzo, komanso amasewera chitetezo. Makulidwe oyenera ndi 15-30μm. 9. Mapangidwe otambasula a pallet mechanism ma phukusi Kuyika kwa filimu yotambasula kuyenera kutambasulidwa. Mitundu yotambasula yamapaketi amakina a pallet imaphatikizapo kutambasula molunjika komanso kutambasula. Kutambasula kusanachitike kumagawidwa m'mitundu iwiri, imodzi ndi yotambasula kale ndipo ina ndi yotambasula yamagetsi. Kutambasula molunjika ndikumaliza kutambasula pakati pa thireyi ndi filimuyo. Chiŵerengero chotambasula cha njirayi ndi chochepa (pafupifupi 15% -20%). Ngati chiŵerengero chotambasula chikuposa 55% ~ 60%, chomwe chimaposa zokolola zoyambirira za filimuyo, m'lifupi mwake filimuyo imachepetsedwa, ndipo ntchito ya puncture imatayikanso. Zosavuta kuswa. Ndipo pamlingo wotambasula 60%, mphamvu yokoka ikadali yayikulu kwambiri, pazinthu zopepuka, zitha kusokoneza katunduyo.
