Parizvino, yakakwirira chipingamupinyi uye akawanda-anoshanda mafirimu ari kusimukira kusvika padanho idzva rehunyanzvi. Kana iri firimu rinoshanda, nekuda kwebasa rayo rinokosha, rinogona kuzadzisa zvirinani zvinodiwa zvekutakura zvinhu, kana zviri nani kusangana nezvinodiwa zvekugadzirisa zvinhu, saka mhedzisiro yacho iri nani uye inokwikwidza mumusika. Pano, isu tichatarisa paBOPP uye PET mafirimu
BOPP, kana Biaxially Oriented Polypropylene, ifirimu repurasitiki rinoshandiswa zvakanyanya mukurongedza uye kunyora. Iyo inopinda biaxial orientation process, ichiwedzera kujeka kwayo, simba, uye kudhinda. Inozivikanwa nekusarudzika kwayo, BOPP inowanzo shandiswa mukurongedza, mabhii, matepi anonamira, uye lamination application. Iyo inopa yakanakisa chigadzirwa kuoneka, kusimba, uye inodzokororwa, zvichiita kuti ive sarudzo yakakurumbira kune dzakasiyana siyana dzekurongedza.
PET, kana Polyethylene Terephthalate, inoshandiswa zvakanyanya thermoplastic polymer inozivikanwa nekusiyana-siyana kwayo uye kujeka. Inowanzo shandiswa mukugadzira mabhodhoro epurasitiki ezvinwiwa, midziyo yechikafu, uye kurongedza, PET inoonekera uye ine yakanakisa chipingamupinyi zvivakwa zvinopesana neokisijeni uye unyoro. Iyo isingaremi, inogara, uye inogona kushandiswazve, zvichiita kuti ive sarudzo yakakurumbira kune akasiyana siyana ekurongedza maapplication. Pamusoro pezvo, PET inoshandiswa mumafibhi ezvipfeko, pamwe nekugadzira mafirimu nemashiti ezvinangwa zvakasiyana.
Musiyano
PET inomirira polyethylene terephthalate, nepo BOPP ichimirira biaxially oriented polypropylene. PET neBOPP mafirimu matete epurasitiki mafirimu anonyanya kushandiswa kurongedza. Dzese isarudzo dzakakurumbira dzekurongedza chikafu uye mamwe maapplication, senge zvigadzirwa zvinyorwa uye ekudzivirira wraps.
Nezve mutsauko uripo pakati pePET neBOPP mafirimu, mutsauko uri pachena ndiwo mutengo. Firimu rePET rinowanzo kudhura kupfuura firimu reBOPP nekuda kwesimba rayo repamusoro uye zvipingamupinyi. Nepo firimu reBOPP richinyanya kudhura, haripe dziviriro imwechete kana chipingamupinyi zvivakwa sePET firimu.
Pamusoro pemutengo, kune misiyano mukupikiswa kwekushisa pakati pemhando mbiri dzefirimu. Firimu rePET rine nzvimbo yakakwira yekunyungudika kupfuura firimu reBOPP, saka rinokwanisa kumira tembiricha yakakwira pasina kuputika kana kuderera. BOPP firimu rinoramba kunyorova, saka rinogona kuchengetedza zvigadzirwa zvinonzwa kunyorova.
Nezve maoptical zvimiro zvePET neBOPP mafirimu, PET firimu rine kujeka kwepamusoro uye kupenya, nepo BOPP firimu rine matte kupera. PET firimu ndiyo sarudzo iri nani kana iwe uchitsvaga firimu rinopa yakanakisa optical zvivakwa.
Mafirimu ePET neBOPP anogadzirwa kubva kumapuranga epurasitiki asi ane zvinhu zvakasiyana. PET inosanganisira polyethylene terephthalate, inobatanidza monomers maviri, ethylene glycol, uye terephthalic acid. Musanganiswa uyu unogadzira yakasimba uye isina huremu zvinhu zvinopikisa kupisa, makemikari, uye zvinonyungudutsa. Kune rimwe divi, firimu reBOPP rinogadzirwa kubva ku biaxially-oriented polypropylene, musanganiswa wepolypropylene uye zvimwe zvinogadzirwa. Ichi chinyorwa zvakare chakasimba uye chakareruka asi chisingachinji nekupisa uye makemikari.
Zvinhu zviviri izvi zvine zvakawanda zvakafanana maererano nemaitiro emuviri. Ose ari maviri akajeka uye ane kujeka kwakanyanya, zvichiita kuti ive yakanakira maapplication ayo anoda kujeka kwezviri mukati. Pamusoro pezvo, zvese zviri zviviri zvinhu zvakasimba uye zvinochinjika, zvichiita kuti zvikwanise kushandiswa kwakasiyana siyana.
Zvisinei, pane misiyano mikuru. PET yakanyanya kuomarara kupfuura firimu reBOPP uye haitani kubvaruka kana kuboora. PET ine nzvimbo yakakwira yekunyungudika uye inoshingirira ku radiation yeUV. Kune rimwe divi, firimu reBOPP rinonyanya kuumbika uye rinogona kutambanudzwa nekuumbwa kuti rikwane akasiyana maapplication.
pfupiso
Mukupedzisa, pet film neBopp film vane misiyano yavo. PET firimu ndeye polyethylene terephthalate firimu, ichiita iyo thermoplastic inogona kupisa uye kuumbwa pasina kurasikirwa kwayo kwemaitiro. Iyo ine yakanakisa dimensional kugadzikana, optical zvivakwa, uye makemikari kuramba, zvichiita kuti ive sarudzo yakanaka kune akawanda maapplication. Iyo Bopp firimu, kune rumwe rutivi, i biaxially-yakatarisana polypropylene firimu. Icho chinhu chakareruka asi chakasimba chine zvakanakisa optical, mechanical, uye thermal properties. Inobatsira mumashandisirwo apo kujekesa kwepamusoro uye simba repamusoro rinodiwa.
Pakusarudza pakati pemafirimu maviri aya, zvakakosha kufunga nezvekushandisa. PET firimu rakanakira maapplication ayo anoda kuwanda kwedimensional kugadzikana uye makemikari kuramba. Bopp firimu rinonyanya kukodzera kune zvikumbiro zvinoda kujeka kwepamusoro uye simba repamusoro.
Tinovimba kuti iyi blog yakubatsira iwe kunzwisisa zvirinani mutsauko uripo pakati pezvipfuyo neBopp mafirimu uye sarudza iyo inonyatsoenderana nechikumbiro chako.
