Polypropylene
Polypropylene (PP) ndeyepamusoro-inonyunguduka-nzvimbo thermoplastic polima ine yakanakisa kurongeka zvivakwa, zvichiita kuti ive imwe yeanovimbisa thermoplastic polymers nhasi.Zvichienzaniswa nezvimwe zvakajairika thermoplastic zvinhu, inopa mabhenefiti akadai semutengo wakaderera, huremu huremu, hukuru hwemagetsi zvinhu zvinosanganisira goho simba, kusimba kwesimba, uye pamusoro pesimba, yakasarudzika kusagadzikana-kupwanya kuramba, uye abrasion kuramba, pamwe nekugadzikana kwakanaka kwemakemikari, kureruka. yekuumba, uye zvakasiyana-siyana zvekushandisa.Yakave ichishandiswa zvakanyanya mumaindasitiri akadai semakemikari, zvemagetsi, mota, kuvaka, uye kurongedza.
Musika wekurongedza wakanyanya kutsiva bepa nemafirimu epurasitiki ekurongedza akapfava, kubva pachikafu kuenda kune zvakasiyana.Mafirimu epurasitiki anoshandiswa kurongedza akapfava anofanirwa kusangana nezvinodiwa zvekudzivirira, kushanda, zviri nyore, uye zvehupfumi zvekurongedza zvinhu, zvine simba rakakodzera, zvipingamupinyi zvivakwa, kugadzikana, kuchengetedzeka, pachena, uye nyore.
CPP Firimu: CPP firimu rinouya mune zvakajairwa-chinangwa, simbi, uye inovira mhando.Iyo general-chinangwa mhando inowanzoshandiswa uye inogona kugadziriswa mukati meimwe siyana.Iyo metallized mhando chigadzirwa chepamusoro-chepamusoro chakagadzirwa kuburikidza neakakosha maitiro uchishandisa yakasarudzika polypropylene zvinhu kuti iwane yepamusoro yekupisa-kuvharisa simba.Rudzi runobikwa rwakagadzirirwa kupikisa kupisa kwakanyanya uye rinowanzo gadzirwa kubva kune zvisina kujairika copolymers ine yakakwirira yekutanga kupisa-kuvharisa tembiricha.
Firimu reCPP ifirimu risina kutwasuka, risingatarisike rakatambanudzwa rakagadzirwa neyakakandirwa firimu nzira kubva isina kutambanudza polypropylene.Inoratidza huremu huremu, kujeka kwepamusoro, kupfava kwakanaka, kusimba kwakanaka, kuchinjika kwemagetsi, kuvharisa-kupisa, kusimba kwehunyoro, uye kupisa kupisa, kunaka kutsvedza zvivakwa, kumhanyisa kugadzirwa kwemafirimu, ukobvu yunifomu, kunyorova kwakanaka, kuramba kwemafuta, kupisa. kupikisa, kutonhora kwekudzivirira, kureruka kwekupisa chisimbiso, uye kupikisa kwepamusoro pakuvhara.Its optical zvimiro zvakanakisa uye zvakakodzera kune otomatiki kurongedza.
Kubva payakaunzwa muChina muma1980s, kudyara uye kukosha kwakawedzerwa kwefirimu reCPP kwave kwakakosha.CPP firimu rinoshandiswa zvakanyanya mukurongedza chikafu, mishonga, stationery, cosmetics, uye machira, nekushandiswa kukuru muchikamu chekurongedza chikafu.Inoshandiswa kurongedza zvikafu zvakabikwa-zvinopisa, zvinonhuhwirira, soups, pamwe nezvigadzirwa zvekunyora, mapikicha, zvinounganidzwa, mavara akasiyana, uye matepi.
BOPP Firimu: BOPP firimu rinogona kuiswa muchikamu nebasa kuita antistatic firimu, anti-fog firimu, porous-yakazadzwa yakagadziridzwa BOPP firimu, uye nyore-kudhinda.
BOPP firimu
BOPP firimu ibasa repamusoro-soro, rakajeka kwazvo rekurongedza iro rakagadzirwa muma1960s.Inopa kuomarara kwepamusoro, simba rekubvarura, kupikisa kurwisa, kunaka kwehunyoro chipingamupinyi, kupenya kwakanyanya, kujeka kwakanaka, yakanaka gasi chinodzivirira zvivakwa, huremu, husina muchetura, husina kunhuhwirira, kugadzikana kwakanaka kwechimiro, kushanda kwakafara, kudhinda kwakanaka, uye yakanaka magetsi ekudzivirira zvinhu. .Inotaridzirwa zvakanyanya se "mambokadzi wekurongedza" muindasitiri yekurongedza.
Antistatic BOPP firimu rinoshandiswa kurongedza zvinhu zvidiki zvekudya sehove dzakachekwa, bhaisikopo riri nyore kudhinda reBOPP rinoshandiswa kurongedza zvigadzirwa zvezviyo, uye bhaisikopo riri nyore kucheka reBOPP rinoshandiswa kurongedza soups nemishonga.BOPP shrink firimu, inogadzirwa uchishandisa biaxially yakatarisana nefirimu yekugadzira maitiro, inowanzoshandiswa pakurongedza fodya.
IPP Firimu: IPP firimu ine zvishoma yakaderera optical zvivakwa pane CPP uye BOPP, asi ine nyore maitiro, yakaderera mutengo, uye inogona kuiswa chisimbiso zviri nyore kumusoro uye kuzasi kwekurongedza.Ukobvu hwefirimu kazhinji hunobva pa0.03 kusvika 0.05mm.Ichishandisa copolymer resins, inogona kugadzira mafirimu ane simba rakanakisa pane yakaderera tembiricha.Akagadziridzwa IPP mafirimu ane yakaderera-tembiricha yakakwira maitiro ekupikisa, yakakwirira kutsvedza zvivakwa, kujeka kwepamusoro, kusimba kwesimba, kuchinjika kwakanaka, uye antistatic zvimiro.Iyo firimu inogona kusanganisira imwe-layer polypropylene firimu, inogona kuve homopolymer kana copolymer, kana akawanda-layer co-extruded blown firimu uchishandisa homopolymer uye copolymer zvinhu.IPP inonyanya kushandiswa kurongedza snacks zvakakangwa, chingwa, machira, maforodha, rekodhi maoko, gungwa, uye shangu dzemitambo.
Iyo yekugadzira maitiro eyakakandirwa polypropylene firimu inosanganisira kunyunguduka uye plasticizing polypropylene resin kuburikidza neextruder, wozoiburitsa kuburikidza neyakamanikana kufa, ichiteverwa nekurebesa kutambanudza uye kutonhora kwezvinhu zvakanyungudutswa pane yekukanda roller, uye pakupedzisira kuita pre-kucheka, ukobvu kuyerwa. , kutsemura, kurapwa kwepamusoro kwekona, uye kupeta mushure mekucheka.Iyo firimu inoguma, inozivikanwa seCPP firimu, haina muchetura, yakareruka, yakakwirira-simba, yakajeka, inopenya, inopisa-inovharika, inodzivirira hunyoro, yakaoma, uye yakafanana gobvu.Iyo ine huwandu hwakasiyana hwekushandisa, zvinosanganisira seanosanganiswa firimu substrates, chikafu chinobikwa uye yakakwirira-tembiricha yekurongedza zvinhu, uye akasiyana ekurongedza zvinhu zvekudya, mishonga, zvipfeko, machira, uye yekuvata.
Pamusoro Kurapa kwePolypropylene Firimu
Corona Kurapa: Kurapwa kwepamusoro kwakakosha kuti mapolymers avandudze kunyorova uye kunamatira muindasitiri yekudhinda uye yekurongedza.Matekiniki akadai segraft polymerization, corona discharge, uye laser irradiation anoshandiswa pakurapa kwepamusoro.Kurapwa kweCorona tekinoroji ine hushamwari nharaunda iyo inowedzera kuwanda kweiyo reactive oxygen radicals pane polymer pamusoro.Inokodzera zvinhu zvakaita se polyethylene, polypropylene, PVC, polycarbonates, fluoropolymers, uye mamwe macopolymers.Kurapwa kweCorona kune nguva pfupi yekurapa, kukurumidza kukurumidza, kushanda kuri nyore, uye kudzora kuri nyore.Iyo inongobata iyo isina kudzika yepasi pepurasitiki, kazhinji padanho re nanometer, uye haina kukanganisa zvakanyanya ma mechanics ezvigadzirwa.Inoshandiswa zvakanyanya kugadzirisa pamusoro pe polyethylene uye polypropylene mafirimu uye fiber, sezvo iri nyore kuisa uye inopa maitiro akanaka ekurapa pasina kusvibiswa kwezvakatipoteredza.
Surface Characteristics yePolypropylene Firimu: Polypropylene firimu chinhu chisiri checrystalline zvinhu, zvichikonzera kusawirirana kweinki uye kuderera kwemvura nekuda kwekufamba uye kuunganidzwa kwezvinhu zvakaderera zvemamorekuru senge mapurasitiki, ekutanga, anosara monomers, uye zvigadzirwa zvinosvibisa, izvo zvinogadzira amorphous. layer inodzikisira kunyorova kwepasi, inoda kurapwa isati yadhinda kuti iwane inogutsa inodhinda mhando.Pamusoro pezvo, chimiro chisiri chepolar chepolypropylene firimu repurasitiki chinopa zvimhingamipinyi zvekugadzirisa kwechipiri senge bonding, coating, lamination, aluminium plating, uye kupisa stamping, zvichikonzera kusakwana kwekuita.
Misimboti uye Microscopic Phenomena yeCorona Kurapa: Pasi pesimba renzvimbo yemagetsi yakakwira-voltage, iyo polypropylene firimu inokanganiswa nekuyerera kweelectronic kune simba, zvichikonzera kuoma kwepasi.Izvi zvinokonzerwa neiyo oxidation process uye mamorekuru cheni yekupwanya zvigadzirwa pane polypropylene firimu repamusoro, zvichitungamira kune yakakwira kumusoro kushushikana kupfuura yekutanga firimu.Kurapa kweCorona kunogadzira huwandu hwakakosha hwemaozone plasma particles anodyidzana zvakananga kana zvisina kunanga nepurasitiki firimu pamusoro, zvichitungamira mukutsemuka kweakakwira ma molecular bond pamusoro uye kugadzirwa kweakasiyana radicals uye unsaturated nzvimbo.Aya asina kudzika pamusoro radicals uye unsaturated centers anobva aita nemvura iri pamusoro kuumba mapoka anoshanda epolar, achimisikidza iyo polypropylene firimu pamusoro.
Muchidimbu, marudzi akasiyana-siyana efirimu repolypropylene uye huwandu hwemashandisirwo, pamwe chete neakasiyana siyana ekurapa tekinoroji, inova nechokwadi chekuti inosangana nezvinodiwa zvekushandisa mukurongedza uye mamwe minda.
