1. JikeleleIfilimu yeBOPP
Ifilimu ye-BOPP yinkqubo apho iifilimu ze-amorphous okanye i-crystalline inxalenye yazo zoluliwe ngokuthe nkqo kwaye ngokuthe tye ngaphezu kwendawo yokuthambisa ngexesha lokucubungula, okukhokelela ekwandeni kwendawo, ukuncipha kobukhulu, kunye nokuphuculwa okubonakalayo kokucwebezela kunye nokungafihli.Kwangaxeshanye, ngenxa yokuqhelaniswa neemolekyuli ezolulayo, amandla abo omatshini, ukungangeni komoya, ukuxhathisa ukufuma, kunye nokumelana nokubanda kuye kwaphuculwa kakhulu.
Iimpawu zeBOPP bhanyabhanya:
Amandla aphezulu kunye ne-elastic modulus, kodwa amandla aphantsi okukrazula;Ukuqina okuhle, ukomelela okubalaseleyo kunye nokumelana nokudinwa;Ubushushu obuphezulu kunye nokumelana nokubanda, kunye nobushushu bokusebenzisa ukuya kuthi ga kwi-120℃.I-BOPP ikwanayo nokumelana nokubanda okuphezulu kuneefilimu zePP jikelele;Iglosi ephezulu yomphezulu kunye nokungafihli kakuhle, kufanelekile ukusetyenziswa njengezinto ezahlukeneyo zokupakisha;I-BOPP inozinzo oluhle lweekhemikhali.Ngaphandle kwee-asidi ezomeleleyo, ezifana ne-Oleum kunye ne-asidi ye-nitric, ayinyibiliki kwezinye izinyibilikisi, kwaye kuphela ii-hydrocarbons ezithile ezinomphumela wokudumba kuyo;Inokumelana namanzi okugqwesileyo kwaye yenye yezona zinto zibalaseleyo zokufuma kunye nokuxhathisa ukufuma, kunye nesantya sokufunxa amanzi esingaphantsi kwe-0.01%;Ngenxa yokungashicileleki kakuhle, unyango lwe-corona yomphezulu kufuneka lwenziwe phambi koshicilelo ukuze kuphunyezwe iziphumo ezilungileyo zoshicilelo;Umbane ophezulu we-static, i-agent ye-Antistatic iya kongezwa kwi-resin esetyenziselwa ukuveliswa kwefilimu.
2. Matte BOPP
Uyilo lomphezulu we-matte BOPP ngumaleko we-matte, okwenza inkangeleko ibe ngathi yiphepha kwaye ikhululekile ukuyiphatha.Umphezulu wokutshabalala awusetyenziselwa ukuvala ubushushu.Ngenxa yobukho boluhlu lokucima, xa kuthelekiswa ne-BOPP ngokubanzi, inezi mpawu zilandelayo: indawo yokucima inokudlala indima yomthunzi, kwaye i-glossiness surface nayo iyancitshiswa kakhulu;Ukuba kuyimfuneko, umaleko wokucima unokusetyenziswa njengesigqubuthelo esishushu;Umphezulu wokuphela unobushelelezi obuhle, njengoko i-surface coarsening ine-anti adhesion kunye nomqulu wefilimu akukho lula ukunamathela;Amandla okuqina kwefilimu yokutshabalala angaphantsi kancinane kunefilimu ngokubanzi, kwaye uzinzo lwe-thermal nalo lubi kakhulu kunolo lwe-BOPP eqhelekileyo.
Ifilimu ye-Pearlescent yenziwe kwi-PP njengento eluhlaza, eyongezwe kunye ne-CaCO3, i-pigment ye-pearlescent, kunye ne-agent ye-rubber modified agent, exutywe kunye ne-biaxially yoluliwe.Ngenxa yokwelula kweeamolekyu ze-resin ze-PP ngexesha lenkqubo yokwelula i-biaxial, umgama phakathi kweengqungquthela ze-CaCO3 zanda, okubangelwa ukubunjwa kwamabhubhu.Ngoko ke, ifilimu ye-pearlescent yifilimu ye-foam encinci ene-0.7g / cm ³ ekhohlo nasekunene.
Iimolekyuli ze-PP ziphulukana neempawu zazo zokutywina ubushushu emva kokuqhelaniswa ne-biaxial, kodwa njengezilungisi ezifana nerabha, ziseneempawu zokutywina ubushushu.Nangona kunjalo, amandla okutywinwa kobushushu aphantsi kwaye kulula ukuwakrazula, okwenza ukuba asetyenziswe ngokuqhelekileyo ukupakishwa kwe-ayisikrimu, iipopsicles, kunye nezinye iimveliso.
4. Ubushushu obuvaliweyo befilimu yeBOPP
Ifilimu enamacala amabini etywina ubushushu:
Lo mboniso bhanyabhanya ubhityileyo unesakhiwo se-ABC, enemigangatho yomibini engu-A no-C evalwe bubushushu.Isetyenziswa kakhulu njengezinto zokupakisha ukutya, impahla, iaudio kunye neemveliso zevidiyo, njl.
Ifilimu enecala elinye yokutywina ubushushu:
Le filimu ibhityileyo inesakhiwo se-ABB, kunye ne-A-layer ibe ngumaleko wokutywina ubushushu.Emva kokushicilela iphethini kwicala le-B, idibaniswe ne-PE, i-BOPP, kunye ne-aluminium foil ukwenza isikhwama, esisetyenziselwa izinto zokupakisha eziphezulu zokutya, iziphuzo, itiye kunye nezinye iinjongo.
5. Cast ifilimu ye-CPP
Ifilimu yeCast yeCPP yepolypropylene yifilimu enganwebekiyo, engajongwanga yepolypropylene.
Iimpawu zefilimu ye-CPP ziphezulu elubala, i-flatness efanelekileyo, ukumelana nobushushu obuphezulu, iqondo elithile lokuqina ngaphandle kokulahlekelwa ukuguquguquka, kunye nokutywinwa kakuhle kobushushu.I-Homopolymer CPP inoluhlu lobushushu obumxinwa lokutywinwa kobushushu kunye nokuqina okuphezulu, okwenza ukuba ilungele ukusetyenziswa njengefilimu yokupakisha yomgangatho omnye,
Ukusebenza kwe-CPP ye-copolymerized ilungelelene kwaye ifanelekile njengempahla yangaphakathi ye-membrane edibeneyo.Okwangoku, ngokubanzi i-co extruded CPP, enokuthi isebenzise ngokupheleleyo iimpawu ze-polypropylene ezahlukeneyo zokudibanisa, ukwenza ukusebenza kwe-CPP kubanzi ngakumbi.
6. Vuthela ifilimu ye-IPP ebunjiweyo
Ifilimu evuthelweyo ye-IPP iveliswa ngokubanzi kusetyenziswa indlela yokuhla.Emva kokuba i-PP ikhutshiwe kwaye yandiswe kumlomo wokubumba we-annular, iqale ipholiswe ngumsesane womoya kwaye icinywe ngokukhawuleza kwaye ibunjwe ngamanzi.Emva kokumisa, ihlanganiswe kwaye iveliswe njengefilimu ye-cylindrical, enokuthi inqunywe kwiifilimu ezincinci.I-IPP ebunjiweyo ye-IPP inokungafihli kakuhle, ukuqina, kunye nokwenziwa kweengxowa ezilula, kodwa ukufana kwayo kobukhulu kubi kwaye ukucaca kwefilimu akulunganga.
