Kufotokozera mwachidule za kukula kwa makampani opanga mafilimu

Filimu yotambasula, yomwe imadziwikanso kuti mapaleti. Ndiloyamba ku China kupanga filimu yotambasula ya PVC yokhala ndi PVC ngati zinthu zoyambira ndi DOA ngati plasticizer ndi ntchito yodzimatira. Chifukwa cha zovuta zachitetezo cha chilengedwe, mtengo wokwera (wokhudzana ndi PE, malo opangira ma unit ang'onoang'ono), kusatambasuka bwino ndi zifukwa zina, filimu yotambasula ya PE idachotsedwa pang'onopang'ono pomwe kupanga filimu ya PE kutambasula kunayambika mu 1994-1995. Kanema wotambasula wa PE poyamba amagwiritsa ntchito EVA ngati zomatira zokha, koma mtengo wake ndi wokwera komanso wokoma. Pambuyo pake, PIB ndi VLDPE zimagwiritsidwa ntchito ngati zomatira zokha. Zinthu zoyambira tsopano ndi LLDPE, kuphatikiza C4, C6, C8 ndi metallocene PE. (MPE). Tsopano gawo la kumpoto kwa China likuimiridwa ndi "TOPEVER" yotambasula filimu yopangidwa ndi Shandong Topever Group, yomwe yapindula ndi makasitomala ochokera m'mayiko ambiri.

Filimu yoyambirira ya LLDPE yotambasula nthawi zambiri inali filimu yowombedwa, kuchokera ku wosanjikiza umodzi kupita ku magawo awiri ndi atatu; tsopano LLDPE kutambasula filimu makamaka amapangidwa ndi kuponyera njira, chifukwa kuponyera mzere kupanga ali ndi ubwino yunifolomu makulidwe ndi mkulu kuwonekera. Itha kugwiritsidwa ntchito pazofunikira za chiŵerengero chapamwamba chisanadze kutambasula. Popeza kuponya kwagawo limodzi sikungakwaniritse kumamatira kumbali imodzi, gawo logwiritsira ntchito ndilochepa. Kuponyedwa kwamtundu umodzi komanso kusanjikiza kawiri sikuli kokulirapo ngati kusanjika kwa magawo atatu posankha zinthu, komanso mtengo wopangira nawonso ndi wokwera, kotero kuti mawonekedwe a magawo atatu a co-extrusion ndi abwino kwambiri. Kanema wotambasulira wapamwamba kwambiri ayenera kukhala ndi mawonekedwe owonekera kwambiri, kutalika kwautali wautali, malo okolola kwambiri, kung'ambika kwamphamvu, komanso kutulutsa bwino.

Gulu La Mafilimu Otambasula

Pakalipano, mafilimu otambasula pamsika amagawidwa m'mitundu iwiri: mafilimu otambasula manja ndi mafilimu otambasula makina malinga ndi ntchito zosiyanasiyana. Makulidwe a filimu yotambasula pamanja nthawi zambiri ndi 15μ-20μ, ndipo makulidwe a filimu yotambasula pamakina ndi 20μ-30μ, kupatula milandu yapadera. Malinga ndi njira yoyikamo, kulongedza filimu yotambasulira kumatha kugawidwa m'mapaketi otambasulira amanja, ma CD otambasulira, komanso kuyika kwanthawi yayitali. Odziwika ndi zinthu, filimu yotambasula ikhoza kugawidwa mu filimu yotambasula ya polyethylene, filimu yotambasula ya polyvinyl chloride, filimu yotambasula ya ethylene-vinyl acetate, ndi zina zotero. kukhala gawo lalikulu la mafilimu otambasula. Malingana ndi momwe filimuyo imapangidwira, filimu yotambasula ikhoza kugawidwa mu filimu yotambasula imodzi ndi filimu yotambasula yambiri. Nthawi zambiri, mbali imodzi yokha imakhala yomata, choncho nthawi zambiri imatchedwa filimu yomata ya mbali imodzi. Ndi kukonza kwa zida zopangira mafilimu ndi ukadaulo, ubwino wa mafilimu otambasulidwa amitundu yambiri, omwe amathandizira kuwongolera zinthu komanso kuchepetsa mtengo wazinthu, wakula kwambiri. Pakalipano, mafilimu otambasulidwa omwe ali ndi mapangidwe amodzi achepa pang'onopang'ono. Malinga ndi njira zosiyanasiyana zopangira ndi kukonza, filimu yotambasula imatha kugawidwa kukhala filimu yowongoleredwa ndi filimu yotambasula, ndipo filimu yotambasulira imakhala ndi magwiridwe antchito abwino. Wodziwika ndi kugwiritsa ntchito, filimu yotambasula imatha kugawidwa kukhala filimu yotambasula yopangira zida zamafakitale (monga filimu yotambasulira zida zanyumba, makina, mankhwala, zida zomangira, ndi zina), filimu yotambasulira zonyamula zaulimi, ndi filimu yotambasula yapanyumba. .

Tambasula Kanema Raw Material

Zopangira zazikulu za filimu yotambasula ndi LLDPE, ndipo kalasi yomwe ikukhudzidwa makamaka ndi 7042. Chifukwa cha zosowa zapadera za filimuyi, 7042N, 1018HA, 1002YB, 218N ndi 3518CB ingagwiritsidwenso ntchito.

Kugwiritsa Ntchito Mafilimu Otambasula

Monga gawo lofunikira kwambiri pamayendedwe onyamula katundu, filimu yotambasula imagwira ntchito yokonza katundu. Amagwiritsidwa ntchito kwambiri popanga mapepala, mayendedwe, makampani opanga mankhwala, zopangira pulasitiki, zomangira, chakudya, magalasi, etc.; mu malonda akunja, kupanga mapepala, hardware, mankhwala apulasitiki, zomangira, Chakudya, mankhwala ndi madera ena. Tinganene kuti paliponse pamene pali kusamutsidwa kwa danga kwa zinthu, pali kukhalapo kwa filimu yathu yotambasula.

Tambasula Mafilimu Opangira Zida

Pankhani yamakina, zida zopangira filimu zapakhomo pano zimagawidwa m'mizere yotumizidwa kunja ndi mizere yopanga zapakhomo. Mizere yopangidwa kuchokera kunja kwenikweni ikuchokera ku Italy, United States, ndi Germany; Mizere yopanga zapakhomo imakhazikika ku Jiangsu, Zhejiang, Hebei, ndi Guangdong. Ndipo Changlongxing Machinery Manufacturing Factory ndi odziwika ku China. Shandong Topever Gulu tsopano anayambitsa angapo mizere kupanga kunja kugwirizana ndi mizere oposa khumi zoweta zoweta kuti atumize kupanga. Malinga ndi zaka zambiri zomvetsetsa zamakampani, mphamvu zopangira zidazo ndizosiyana m'malo osiyanasiyana. Liwiro lopanga la mzere wopanga zoweta ndi 80-150 m / min. M'zaka zaposachedwa, zida zapakhomo zothamanga kwambiri za 200-300 m / min zili mu gawo la kafukufuku ndi chitukuko; pamene liwiro la kupanga mzere wotumizidwa kunja kwawonjezeka kufika 300-400 m / min, 500 m / min Mzere wothamanga kwambiri watulukanso. Zida zopangira mafilimu otambasula zimasiyanasiyana pamtengo chifukwa cha m'lifupi mwake komanso kuthamanga kwake. Pakalipano, makina opangira mafilimu opangira ulusi wa 0.5m omwe amagwiritsidwa ntchito pamanja ndi 70,000-80,000 / chidutswa, ndipo makina opanga mafilimu otambasula ndi 90,000-100,000 / chidutswa; Ulusi wa mita 1 ndi 200,000-250,000 / chidutswa; Mzere wa 2.0-mita uli pakati pa 800,000 ndi 1.5 miliyoni / chidutswa.
