Firimu reOPP imhando yefirimu repolypropylene, iro rinonzi co-extruded oriented polypropylene (OPP) firimu nekuti maitiro ekugadzira imhando ye multi-layer extrusion. Kana paine maitiro ekutambanudza maviri-directional mukugadzirisa, inonzi bi-directional oriented polypropylene firimu (BOPP). Rimwe rinonzi cast polypropylene film (CPP) kusiyana nemaitiro e co-extrusion. Mafirimu matatu aya akasiyana muhunhu hwavo uye mashandisirwo awo.
I. Mashandisirwo makuru efirimu reOPP
OPP: polypropylene yakarongwa (firimu), polypropylene yakarongwa, imwe mhando yepolypropylene.
Zvigadzirwa zvikuru zvakagadzirwa neOPP:
1, tepi yeOPP: firimu re polypropylene se substrate, rine simba guru rekudhonza, rakareruka, risina chepfu, harina kunaka, rine hushamwari kune nharaunda, rine mashandisirwo akasiyana-siyana uye mamwe mabhenefiti
2, mazita eOPP:nekuti musika une zvigadzirwa zvezuva nezuva zvakapfava uye zvakafanana, chitarisiko ndicho chinhu chikuru, pfungwa yekutanga inosarudza maitiro emutengi ekutenga. Shampoo, gel yekugeza, sipo nezvimwe zvigadzirwa zvinoshandiswa mudzimba dzekugezera nekicheni dzinodziya uye dzine hunyoro, zvinodiwa nechiratidzo kuti zvitsungirire hunyoro uye hazvidonhe, uye kuramba kwayo kubuda kunofanirwa kuenzaniswa nebhodhoro, nepo mabhodhoro akajeka ekuti aratidzike pachena ezvinamira uye zvinyorwa zvinopa zvinodiwa zvakaoma.
Mazita eOPP kana tichienzanisa nemapepa, ane kujeka, simba rakawanda, hunyoro, haasi nyore kudonha uye mamwe mabhenefiti, kunyangwe mutengo wacho wakawedzera, asi anogona kuwana kuratidzwa kwematafura kwakanaka uye mhedzisiro yekushandisa. Asi anogona kuwana kuratidzwa kwematafura kwakanaka uye mhedzisiro yekushandisa. Nekuvandudzwa kwetekinoroji yekudhinda yemuno, tekinoroji yekuputira, kugadzirwa kwematafura efirimu anozvinamira uye matafura ekudhinda efirimu hakusisiri dambudziko, zvinogona kufanotaurwa kuti kushandiswa kwematafura eOPP mudzimba kucharamba kuchiwedzera.
Sezvo zita racho riri PP, rinogona kusanganiswa zvakanaka nePP/PE container surface, tsika yakaratidza kuti OPP firimu ndiyo inonyanya kushandiswa pakunyora mazita emu-mold, chikafu neindasitiri yemakemikari yezuva nezuva muEurope yave ichishandisa nhamba huru yekushandiswa, uye zvishoma nezvishoma yakapararira kumakambani epamba, vashandisi vakawanda vakatanga kuteerera kana kushandisa maitiro ekunyora mazita emu-mold.
Chechipiri, chinangwa chikuru chefirimu reBOPP
BOPP: Firimu repolypropylene rakanangana neBiaxial, zvakare rudzi rumwe rwepolypropylene.
Mafirimu eBOPP anoshandiswa zvakanyanya anosanganisira:
● firimu repolypropylene rinotaridzika kaviri,
● firimu re polypropylene rakavharirwa nekupisa,
● firimu rekuputira fodya,
● firimu re polypropylene pearlescent rine mativi maviri,
● firimu resimbi rakagadziriswa nepolypropylene rine mativi maviri,
● firimu risina kusimba nezvimwewo.
Mashandisirwo makuru emafirimu akasiyana-siyana ndeaya anotevera:
1, firimu reBOPP renguva dzose
Inonyanya kushandiswa pakudhinda, kugadzira mabhegi, se tepi inonamira uye inosanganisa nezvimwe zvinhu.
2, BOPP kupisa chisimbiso firimu
Inonyanya kushandiswa pakudhinda, kugadzira mabhegi nezvimwewo.
3, BOPP firimu rekuputira fodya
Mashandisirwo: Inoshandiswa pakurongedza fodya nekukurumidza.
4, BOPP firimu rakacheneswa
Inoshandiswa pakurongedza chikafu nezvigadzirwa zvemumba mushure mekudhindwa.
5, BOPP Metallized Firimu
Inoshandiswa se vacuum metallization, mwaranzi, substrate yekurwisa-yenhema, uye kurongedza chikafu.
6, BOPP matte firimu
Inoshandiswa sipo, chikafu, fodya, zvizoro, mishonga nezvimwe zvinhu zvinoiswa mumabhokisi ekurongedza.
7, BOPP anti-mhute firimu
Inoshandiswa pakurongedza miriwo, michero, sushi, maruva nezvimwewo.
Firimu reBOPP chinhu chakakosha kwazvo chekurongedza chinochinjika, chinoshandiswa zvakanyanya.
Firimu reBOPP harina ruvara, harinhuwi, harina kunaka, harina chepfu, uye rine simba guru rekudhonza, simba rekubaya, kuomarara, kusimba uye kujeka kwakanaka.
Simba repamusoro pefirimu reBOPP rakaderera, rinonamira kana kudhinda risati ragadzirwa korona. Zvisinei, firimu reBOPP mushure mekugadzirwa korona, rinogona kuchinjika zvakanaka pakudhinda, rinogona kudhinda nemavara uye kuwana chitarisiko chakanaka, uye nekudaro rinowanzoshandiswa sechigadzirwa chepamusoro pefirimu.
Firimu reBOPP rinewo zvikanganiso, zvakaita sekuti magetsi asingachinjiki ari nyore kuunganidza, hapana kuvharwa kwekupisa nezvimwewo. Mukugadzirwa kwemagetsi ekumhanya kukuru, firimu reBOPP rinowanzobatwa nemagetsi asingachinjiki, saka rinoda kuiswa remover yemagetsi asingachinjiki.
Kuti uwane firimu reBOPP rinovharwa nekupisa, kurapwa kwecorona pamusoro pefirimu reBOPP kunogona kuputirwa nechinamira cheresin chinovharwa nekupisa, senge PVDC latex, EVA latex, nezvimwewo, Inogonawo kuputirwa nenamira inonyungudutsa, asiwo nzira yekuwedzera kana yekubatanidza laminating inogona kushandiswa kugadzira firimu reBOPP rinovharwa nekupisa. Firimu iri rinoshandiswa zvakanyanya muchingwa, mbatya, shangu nemasokisi, pamwe nefodya, nemabhuku.
Kutanga kwesimba rekubvarura mushure mekutambanudza firimu reBOPP kwawedzera, asi simba rekubvarura rechipiri rakaderera zvikuru, saka firimu reBOPP harigone kusiiwa kumativi ese ekupedzisira kwenotch, zvikasadaro firimu reBOPP riri nyore kubvarura mukudhinda, richiravira.
BOPP yakafukidzwa netepi inonamira inogona kugadzirwa kuti ivhare tepi yebhokisi, uye chiyero cheBOPP chinonamira cheBOPP chakafukidzwa netepi inonamira chinogona kugadzira tepi inonamira, uye ndiyo nzira inoshandiswa neBOPP mumusika mukuru.
Mafirimu eBOPP anogona kugadzirwa nenzira yechubhu kana nzira yeflat film. Hunhu hwemafirimu eBOPP anowanikwa nenzira dzakasiyana dzekugadzirisa hwakasiyana. Firimu reBOPP rinogadzirwa nenzira yeflat film nekuda kwehuwandu hukuru hwekudhonza (kusvika ku8-10), saka simba rayo rakakwirira kupfuura nzira yechubhu film, kufanana kweukobvu hwefirimu kuri naniwo.
Kuti pave nekushanda kuri nani, nzira iyi inowanzo shandiswa mukugadzira nzira ye multi-layer composite. BOPP inogona kusanganiswa nezvinhu zvakasiyana-siyana kuti isangane nezvinodiwa zvekushandisa kwakakosha. Zvakadai seBOPP inogona kusanganiswa neLDPE (CPP), PE, PT, PO, PVA, nezvimwewo kuti iwane gasi rinovhara zvakanyanya, hunyoro hunovhara, kujeka, kupisa kwakanyanya uye kwakaderera, kubika uye mafuta anovhara, mafirimu akasiyana-siyana anogona kushandiswa pakudya kune mafuta.
Chechitatu, chinangwa chikuru chefirimu reCPP
CPP: kujeka kwakanaka, kupenya kwakanyanya, kuomarara kwakanaka, kudzivirira hunyoro hwakanaka, kudzivirira kupisa kwakanyanya, kuvhara kupisa kuri nyore nezvimwewo.
Firimu reCPP mushure mekudhinda, kugadzira mabhegi, rakakodzera: mabhegi ezvipfeko, mabhegi ekurukwa nemaruva; firimu remagwaro nemaalbum; kurongedza chikafu; uye yekurongedza zvinodzivirira uye firimu rekushongedza resimbi.
Zvingangoshandiswa zvinosanganisirawo: kuputira chikafu, kuputira chikafu neforoma yakamonyoroka, kurongedza mishonga (mabhegi ekuisa musanganiswa wemafuta), kutsiva PVC muma album emifananidzo, maforodha nemagwaro, bepa rekugadzira, matepi anozvinamira, zvibatiso zvemakadhi ebhizinesi, zvinosunga mhete uye zvinhu zvinosanganisa mabhegi ekusimudzira.
CPP ine simba rakanaka rekudzivirira kupisa.
Sezvo nzvimbo yekunyorovesa yePP iri 140°C, rudzi urwu rwefirimu runogona kushandiswa munzvimbo dzakadai sekuisa zvinhu zvinopisa, mabhegi ekuputira uye kurongedza zvinhu zvisina utachiona.
Pamwe chete nekusagona kunwa acid, alkali uye mafuta, inoita kuti ive chinhu chinosarudzwa munzvimbo dzakadai sekurongedza zvigadzirwa zvechingwa kana zvinhu zvakaiswa laminated.
Kuchengetedzwa kwayo pakusangana nechikafu, kugona kwayo kuratidzwa kwakanaka, hazvikanganisi kunaka kwechikafu chiri mukati, uye zvinogona kusarudza mhando dzakasiyana dzeresin kuti zviwane hunhu hwaunoda.
