Zipangizo zodziwika bwino zamamatumba apulasitiki:
1. Polyethylene
Ndi polyethylene, yomwe imagwiritsidwa ntchito kwambiri m'matumba apulasitiki. Ndi yopepuka komanso yowonekera. Ili ndi ubwino wokhala ndi chinyezi chokwanira, kukana kwa okosijeni, kukana kwa asidi, kukana kwa alkali, kusindikiza kutentha, ndi zina zotero, ndipo ilibe poizoni, yopanda phokoso komanso yopanda fungo. Pakunyamula miyezo yaukhondo. Ndizomwe zimalumikizana bwino ndi thumba lazakudya padziko lonse lapansi, ndipo matumba onyamula zakudya pamsika nthawi zambiri amapangidwa ndi izi.
2. Polyvinyl kolorayidi/PVC
Ndilo mtundu wachiwiri waukulu wa pulasitiki padziko lapansi pambuyo pa polyethylene. Ndi chisankho chabwino pamatumba oyika pulasitiki, matumba a PVC, matumba ophatikizika, ndi zikwama zowulutsira. Itha kugwiritsidwanso ntchito kulongedza ndikukongoletsa zovundikira monga mabuku, zikwatu, ndi matikiti.
3. Otsika osalimba polyethylene
Polyethylene yotsika kachulukidwe ndiyomwe imagwiritsidwa ntchito kwambiri m'mafakitale opangira mapulasitiki ndi kusindikiza m'maiko osiyanasiyana. Ndiwoyenera kuwulutsa kuti asinthidwe kukhala mafilimu a tubular, ndipo ndi oyenera kulongedza zakudya, kuyika mankhwala tsiku lililonse, komanso kuyika kwa fiber product.
4. Mkulu wosalimba polyethylene
Polyethylene yapamwamba kwambiri, yosasunthika kutentha, yophika kuphika, yosazizira komanso yozizira, yosasunthika, yopanda madzi, yopanda mpweya komanso insulating, yosavuta kuwonongeka, ndipo mphamvu zake ndizowirikiza kawiri kuposa polyethylene yotsika kwambiri. Ndizinthu zomwe zimagwiritsidwa ntchito pamatumba apulasitiki.
Huizhou Dingli Packaging Products Co., Ltd., katswiri wopanga thumba la pulasitiki, ali ndi zaka 16 pakupanga matumba apulasitiki, ndipo amatha kukupatsirani matumba apulasitiki makonda, matumba onyamula mapepala, makatoni, mabokosi a pizza, mabokosi a hamburger, ayezi. mbale zonona zonona, chakudya Kufunsira mtengo wa matumba olongedza, matumba a tchipisi ta mbatata, matumba onyamula zokhwasula-khwasula, matumba onyamula khofi, matumba a fodya, makonda ndi matumba apulasitiki, ndi mapepala.
Zipangizo zodziwika bwino zamatumba apulasitiki ndi izi:
1. PE pulasitiki phukusi thumba
Polyethylene (PE), wotchedwa PE, ndi mkulu-maselo organic pawiri wopezedwa powonjezera polymerization wa ethylene. Imazindikiridwa ngati chinthu chabwino chokhudzana ndi chakudya padziko lapansi. Polyethylene ndi umboni wa chinyezi, anti-oxidant, acid-resistant, alkali-resistant, non-poizoni, osakoma, osanunkhiza, ndipo imagwirizana ndi miyezo yaukhondo yonyamula zakudya, ndipo imadziwika kuti "maluwa apulasitiki".
2. PO matumba apulasitiki
PO pulasitiki (polyolefin), yotchedwa PO, ndi polyolefin copolymer, yomwe ndi polima yotengedwa kuchokera ku olefin monomers. Opaque, brittle, non-toxic, amagwiritsidwa ntchito ngati matumba a PO, matumba a PO, makamaka matumba apulasitiki a PO.
3. PP pulasitiki ma CD thumba
Chikwama chapulasitiki cha PP ndi thumba la pulasitiki lopangidwa ndi polypropylene. Nthawi zambiri imagwiritsa ntchito kusindikiza kwamitundu, kusindikiza kwa offset, ndipo imakhala ndi mitundu yowala. Ndi pulasitiki yotambasuka ya polypropylene ndipo ndi yamtundu wa thermoplastic. Pamwamba pawopanda poizoni, wopanda fungo, wosalala komanso wowonekera.
4. Chikwama cha pulasitiki cha OPP
Zinthu za thumba la pulasitiki la OPP ndi polypropylene, bidirectional polypropylene, yomwe imadziwika ndi kuyaka kosavuta, kusungunuka ndi kudontha, chikasu pamwamba ndi buluu pansi, utsi wochepa pambuyo pochoka pamoto, ndikupitiriza kuyaka. Ili ndi mawonekedwe owonekera kwambiri, brittleness, kusindikiza bwino komanso kutsutsa mwamphamvu.
5. Matumba apulasitiki a PPE
Chikwama cha pulasitiki cha PPE ndi chinthu chopangidwa ndi kuphatikiza kwa PP ndi PE. Mankhwalawa ndi fumbi, anti-bacteria, chinyezi-proof, anti-oxidation, kutentha kwambiri, kukana kutentha, kukana mafuta, kusakhala ndi poizoni komanso kosakoma, kuwonekera kwambiri, mphamvu zamakina, anti-blasting Kuchita bwino kwambiri, kulimba. kukana nkhonya ndi misozi kukana.
6. Matumba apulasitiki a Eva
Chikwama cha pulasitiki cha EVA (chikwama chozizira) chimapangidwa makamaka ndi zinthu zokometsera za polyethylene komanso zinthu zofananira, zomwe zimakhala ndi 10% EVA. Kuwonekera bwino, chotchinga mpweya, chinyezi-umboni, kusindikiza kowala, thumba lowala thupi, angayesere kuunikila makhalidwe a mankhwala palokha, ozoni kukana, retardant lawi ndi makhalidwe ena.
7. PVC matumba apulasitiki
PVC zipangizo monga frosted, wamba mandala, kopitilira muyeso mandala, chilengedwe ochezeka otsika kawopsedwe, zachilengedwe ochezeka zinthu sanali poizoni (6P mulibe phthalates ndi mfundo zina), ndi zina zotero, komanso mphira ofewa ndi wolimba. Ndizotetezeka, zaukhondo, zokhazikika, zokongola komanso zothandiza, zowoneka bwino komanso masitayelo osiyanasiyana, ndipo ndizosavuta kugwiritsa ntchito. Ambiri opanga mankhwala apamwamba nthawi zambiri amasankha matumba a PVC kuti asungunuke, kukongoletsa bwino zinthu, ndikusintha khalidwe la mankhwala.
Zomwe tafotokozazi ndi zina mwazinthu zomwe zimagwiritsidwa ntchito kwambiri m'matumba apulasitiki. Posankha, mutha kusankha zinthu zoyenera kupanga matumba apulasitiki apulasitiki malinga ndi zosowa zanu zenizeni
