Ndi paketi yamtundu wanji yomwe imakukopani kwambiri?

Pamene dziko likuchulukirachulukira ndiutsogoleri woteteza chilengedwe, kufunafuna kwa ogula ku ungwiro, zowoneka bwino komansochilengedwe chobiriwirakutetezedwa kwa zinthu zopangidwa ndi mitundu yosiyanasiyana kwapangitsa eni ake ambiri kuti awonjezere gawo la pepala pamapangidwe ake.Kuphatikizapo mkonzi mwiniwake, ndimakondanso kuyika mapepala, ndipo nthawi zambiri ndimatenga matumba amtundu uwu.Zomwe kampani yathu idamalizidwa ndi yodabwitsa kwambiri, monga akhofi kraft pepala zipper thumba ndi mpweya valavuzomwe tangopanga posachedwa.

Mapangidwe a mapepala apulasitiki opangidwa ndi mapepala ndi atsopano komanso apadera, omwe abweretsa zotsatira zodabwitsa kwa eni ake amtundu.Komabe, popanga,, njira zophatikizika zomwe zimagwiritsidwa ntchito zimaphatikizapo zowuma zowuma, zowonjezera zowonjezera, zosungunulira zopanda zosungunulira, ndi zina zotero, zomwe zimapangitsanso njira zina kukhala zosakhazikika, monga zinyalala zambiri, fungo, zotsalira zosungunulira zambiri, ndi zina zambiri. Mavuto monga kutentha kusindikiza ndi matuza.Kupititsa patsogolo mapangidwe a mapepala apulasitiki-pulasitiki, ndikofunikira kuti muyambe ndi ndondomekoyi pamaziko a kumvetsetsa mozama za mtundu uwu wa ma CD, kuti mukwaniritse zotsatira ziwiri ndi theka la khama.

1. Mkhalidwe wamakono wa mapepala apulasitiki ophatikizika

Pankhani yamapangidwe, pali mitundu yosiyanasiyana yazinthu zamapulasitiki pamsika, zomwe zimagawidwa kukhala OPP//PAP, PET//PAP, PAP//CPP(PE), PAP//AL, ndi zina zambiri. pepala: mtundu uliwonse umasankha mitundu yosiyanasiyana ya pepala, makulidwe ndi kulemera kwa pepala ndizosiyana, kuyambira 20 mpaka 100g.Njira yopanga imaphatikizapoextrusion compounding, youma compounding, zosungunulira zopanda zosungunulira, ndi zina.

Kupyolera mu kuyerekeza pamwamba, ndondomeko iliyonse ili ndi ubwino ndi zovuta zake.M'mawu osavuta, zosungunulira zopanda zosakaniza zili ndi ubwino pakuchita bwino, monga kuyendetsa bwino, kutaya, ndi zina zotero. Ngati kuchuluka kwa dongosolo kuli kochepa ndipo dongosolo ndilovuta, timalimbikitsabe kusakaniza kowuma (tcherani khutu ku kusankha pepala, guluu. , ndi zina).

2. Kusankha zipangizo

Pali mitundu yambiri yazinthu zamapepala zomwe zingagwiritsidwe ntchito popanga zinthu zopangidwa ndi pepala-pulasitiki, kuphatikiza mapepala okutidwa, pepala loyera la kraft, pepala lachikasu la kraft, mapepala omatira pawiri, mapepala olembera, mapepala opepuka, ngale, mapepala ofewa, pepala loyambira, etc., komanso malinga ndi kapangidwe kazinthu zopangira, zitha kupangidwa kukhala zinthu zosiyanasiyana, monga OPP/pepa, PET/pepa, CPP//paper, PE//paper, AL//paper, etc.

Pali mitundu yambiri yamagulu malinga ndi ntchito zosiyanasiyana, njira, ndi zina, zomwe zimagwiritsidwa ntchito popanga ma CD osinthika ndi mapepala a kraft, pepala loyera la kraft, pepala lofewa la thonje, pepala loyambira, pepala la ngale, etc., kuchuluka kwa 25gsm. ku 80gsm.Chifukwa cha kuchuluka kwa mapepala ndi ntchito zosiyanasiyana, mfundo zotsatirazi ziyenera kutsatiridwa mukamagwiritsa ntchito mapepala osiyanasiyana:

① - Kawirikawiri, mbali yosalala ya pepala ndi yosavuta kugwirizanitsa ndi filimuyo, pamene mbali yovuta ndi filimuyi ndizovuta kugwirizana.Izi zimachitika makamaka chifukwa cha maenje ndi maenje omwe ali mbali yoyipa.Zomatira zimadzaza mabowo.

②Samalani ndi kuchuluka kwa mapepala.Ulusi wa mapepala ena ndi otayirira kwambiri.Ngakhale kuti pepala ndi filimuyo zimagwirizanitsidwa bwino pamene zili laminated, zimakhala zovuta ku delamination pambuyo pa kusindikiza kutentha.

③ Chinyezi chomwe chili pamapepala chimakhalanso ndi mphamvu yolumikizirana.Malinga ndi zomwe wakumana nazo, chinyezi cha pepala sichiyenera kupitirira 0.4%.Ndibwino kusiya pepala mu uvuni kwa masiku 1 mpaka 2 musanapangidwe

④ Samalani ndi ukhondo wa pepala.

3. Mapangidwe apangidwe

Popanga mapangidwe a chidebe chopangira mapepala-pulasitiki, ndikofunikira kumvetsetsa zomwe zimapangidwira ndikusankha zinthu zoyenera ndi kapangidwe kake.

Pankhani ya thumba lachikwama, nthawi zambiri amagwiritsidwa ntchito popanga zinthu zolimba, ndipo mawonekedwe ake ndi ofewa.Poganizira ntchito yonyamula katundu ndi zofunikira zowonetsera mankhwala, dongosololi likhoza kugawidwa m'magulu atatu: palibe mtundu wawindo, mtundu wa zenera ndi zenera lapadera.

Chikwama chopanda mazenera ndicho chofala kwambiri chamtundu wa thumba.Thupi lalikulu ndi mapepala (monga mapepala a kraft), ndipo zigawo zamkati ndi zakunja nthawi zambiri zimatetezedwa ndi mafilimu apulasitiki monga PE (polyethylene) ndi PP (polypropylene), zomwe zingathe kulepheretsa chinyezi ndi mpweya kuti zisawonongeke Zinthuzo zimawonongeka. , ndipo kuumba kwake kumakhala kofanana ndi kuyika kwa mapulasitiki osinthika.Choyamba, pepalalo limaphatikizidwa ndi filimu ya pulasitiki ndiyeno kutentha-kusindikizidwa kuti apange matumba;

Chikwama cha zenera ndi zenera lokhala ndi mawonekedwe apadera ndi amtundu wa thumba lazenera, ndipo pepala limagwiritsidwa ntchito popanga mabowo a mpweya pang'ono, kotero kuti zoyikapo zitha kuwonetsa masitayelo osiyanasiyana.Kuphatikiza pa kusunga kuwonekera kwa thumba loyikamo, lingakhalenso ndi mawonekedwe a pepala.Njira yopangira thumba lazenera ndikuphatikiza filimu yapulasitiki yopapatiza ndi mapepala awiri ndi filimu ina yapulasitiki yotambalala.Pali njira ziwiri zopangira mazenera apadera.Chimodzi ndikutsegula zenera muzinthu zamapepala pasadakhale kuti mupange mawonekedwe osiyanasiyana, ndikuphatikiza zinthuzo.Zinthu zamagulu ophatikizika zimathanso kusinthidwa ndikupangidwa m'malo ambiri kuti zithandizire kusinthasintha kwa kupanga.

4. Njira yopangira

The youma compounding ndondomeko ndi okhwima.Makampani amasankha guluu wamagulu awiri osungunulira, komanso amasankha guluu wagawo limodzi ndi guluu wamadzi.Apa tikuwonetsa kuti ngakhale guluu ligwiritsidwa ntchito bwanji, mfundo zotsatirazi ziyenera kutsatiridwa:

a.Kusankha mapepala ndikofunikira kwambiri;

b.Kuwongolera kwamadzi pamapepala;

c, pepala lonyezimira ndi kusankha kwa matte;

d.Samalani ndi ukhondo wa pepala;

e, kulamulira kuchuluka kwa guluu;

f.Kuwongolera liwiro kuti zotsalira za zosungunulira zikhale zokwera kwambiri.
