"Polypropylene inogadzirwa kubva ku polymerization yegasi mushure mekupisa kwakanyanya kwepetroleum pasi pechiito chezvinokonzeresa, zvinoenderana neyakasiyana nzira dzekugadzira firimu dzinogona kuwanikwa kubva kune akasiyana mashandiro emafirimu, anowanzoshandiswa kunyanya-chinangwa BOPP, matte BOPP, pearl firimu, kupisa-yakavharwa BOPP, cast CPP, blow molding IPP, etc.
1, General chinangwa BOPP firimu
firimu reBOPP rinogadziriswa kuitira kuti chikamu cheamorphous kana chikamu chekristalline firimu chakatambanudzwa mukufamba kwenguva uye kutenderera kwepamusoro penzvimbo yekunyorovesa, kuitira kuti nzvimbo yefirimu iwedzere, kubwinya kunotetepa, uye kupenya uye kujeka kunovandudzwa zvikuru. Panguva imwecheteyo, simba remuchina, kusimba kwemhepo, kuvharidzira hunyoro uye kutonhora kwekudzivirira kunovandudzwa zvakanyanya nekuda kwekutarisa kwemamorekuru akatambanudzwa.
Zvimiro zveBOPP firimu:
Kusimba kwakasimba, yakakwira modulus ye elasticity, asi yakaderera kubvarura simba; kuomarara kwakanaka, kureba kwakatanhamara uye kuramba kukotamisa kuneta kuita; kupisa uye kutonhora kuramba kwakakwira, kushandiswa kwekushisa kusvika 120 ℃, BOPP kutonhora kwekudzivirira zvakare kwakakwira kupfuura general PP firimu; kubwinya kwepamusoro, kujeka kwakanaka, kwakakodzera kune zvakasiyana-siyana zvekutakura zvinhu; BOPP kugadzikana kwemakemikari kwakanaka, kuwedzera kune yakasimba acids, yakadai sefuming sulfuric acid, nitric acid ine corrosive effect pairi Mukuwedzera, haigadziriswi mune zvimwe zvinonyungudutsa, uye mamwe mahydrocarboni chete ane kuputika pairi; yakanakisa kudzivirira kwemvura, chimwe chezvinhu zvakanakisa zvekunyorova uye hunyoro kuramba, kunyura kwemvura <0.01%; kusanyanya kudhinda, saka iyo yepamusoro inofanirwa kurapwa korona isati yadhindwa, yakanaka kudhinda mhedzisiro mushure mekugadzirisa; high static magetsi, resin inoshandiswa mukugadzira firimu inoda kuwedzerwa kune antistatic agent.
2, Matte BOPP
Iyo yepamusoro ye matte BOPP yakagadzirwa sematte layer, iyo inoita kuti kutaridzika kwechimiro chifanane nebepa uye kugadzikana kune kubata. Matte surface layer haiwanzo kushandiswa kupisa chisimbiso, nekuda kwekuvapo kwematte layer, kana ichienzaniswa nehuwandu-chinangwa BOPP, ine maitiro anotevera: matte surface layer inogona kuita shading basa, iyo gloss yepamusoro inoderedzwawo zvikuru; matte layer inogona kushandiswa kupisa chisimbiso kana zvichidikanwa; matte surface layer yakatsetseka uye yakanaka, nekuti iyo pamusoro yakaomeswa ne-anti-adhesive, firimu rolls haisi nyore kunamatira; matte firimu tensile simba rakadzikira zvishoma pane iyo general-chinangwa firimu, kugadzikana kwekupisa kunonzi zvakare yakajairwa BOPP zvishoma zvakanyanya.
3, firimu rePearlescent
Iyo pearlescent firimu yakagadzirwa nePP, CaCO3, pearlescent pigment uye rubber hood modifier inowedzerwa uye yakasanganiswa nebi-directional kutambanudza. Sezvo ma PP resin mamorekuru anotambanudzwa panguva ye biaxial kutambanudza maitiro, uye zvimedu zveCaCO3 zvakatambanudzwa zvakaparadzana kubva kune mumwe nemumwe, zvichigadzira pore bubbles, saka pearlescent firimu iine microporous furo firimu rine density yakatenderedza 0.7g/cm³.
PP molecule inorasikirwa nekuvharika kwayo kwekupisa mushure mekuita biaxial, asi ichine kumwe kupisa sealability serabha uye mamwe madhizaini, asi kupisa kwesimba rekuvhara rakadzika kwazvo uye nyore kubvarura, iyo inowanzoshandiswa mukurongedza ice cream, popsicle, nezvimwe.
4, Kupisa kuvhara BOPP firimu
Firimu remativi maviri-rakavharwa kupisa:
Iyi firimu ndeye ABC chimiro, A uye C mativi echisimbiso chekupisa. Inonyanya kushandiswa sezvinhu zvekurongedza zvekudya, machira, odhiyo uye vhidhiyo zvigadzirwa, nezvimwe.
Single-sided heat seal film:
Iri rudzi rwefirimu chimiro cheABB, chine A layer sechisimbiso chekupisa. Mushure mekudhinda mapatani padivi reB, inoiswa laminated nePE, BOPP uye aluminiyamu foil kugadzira mabhegi, ayo anoshandiswa seyepamusoro-giredhi ekurongedza zvinhu zvekudya, zvinwiwa, tii, nezvimwe.
5, Kuyerera-kunonoka CPP firimu
Cast CPP polypropylene firimu firimu risiri-kutambanudza, risiri-directional polypropylene firimu.
CPP firimu inoratidzwa nekujeka kwepamusoro, kupfava kwakanaka, yakanaka yakakwirira tembiricha kuramba, imwe nhanho yekuchinjika pasina kurasikirwa nekushanduka, yakanaka yekuisa chisimbiso chekushisa. Homopolymer CPP ine hutete hwakatetepa hwekuisa chisimbiso tembiricha uye yakakwirira brittleness, ichiita kuti ive yakakodzera kushandiswa seimwe-layer yekurongedza firimu.
Co-polymer CPP ine maitiro akaenzana uye akakodzera semukati wemukati weiyo composite firimu. Parizvino, iwo general ari co-extruded CPP, anogona kushandisa zvizere akasiyana epolypropylene maitiro emusanganiswa, zvichiita kuti CPP iite yakawandisa.
6, Yakavhuvhuta IPP firimu
IPP inofefetera firimu inowanzo gadzirwa nenzira yekudzika-kuvhuvhuta, PP inoburitswa uye kupeperetswa mumhete kufa muromo, pakarepo mushure mekutanga kutonhora nemhepo mhete, yakaumbwa nekutonhora kwemvura yekukurumidzira, yakaomeswa uye yakakungurutswa, chigadzirwa chakapedzwa icylinder firimu, iyo inogona zvakare kutemwa kuita pepa refirimu. Yakavhuvhuta IPP ine kujeka kwakanaka, kusimba kwakanaka uye nyore kugadzira bhegi, asi ukobvu hwayo hwakafanana hwakashata uye firimu flatness haina kukwana.
