"I-polypropylene yenziwe kwi-polymerization yegesi emva kokuqhekeka kobushushu obuphezulu be-petroleum phantsi kwesenzo se-catalysts, ngokweendlela ezahlukeneyo zokucubungula ifilimu inokufumaneka kwiifilimu ezahlukeneyo zokusebenza, ezisetyenziswa ngokuqhelekileyo ngokubanzi-injongo ye-BOPP, i-matte BOPP, ifilimu yeperile, i-BOPP etywinwe ngobushushu, i-CPP yokuphosa, ukubumba i-IPP, njl. iifilimu ngokweenkcukacha.
I-1, ifilimu yeBOPP yenjongo ngokubanzi
Ifilimu ye-BOPP icutshungulwa ukwenzela ukuba inxalenye ye-amorphous okanye inxalenye yefilimu ye-crystalline yoluliwe kwi-longitudinal kunye ne-transverse izikhombisi-ndlela ngaphezu kwendawo yokuthambisa, ukwenzela ukuba indawo yefilimu inyuke, ubukhulu buncitshiswe, kwaye i-gloss kunye nokungafihli kuphuculwe kakhulu. Kwangaxeshanye, amandla omatshini, ukuxinana komoya, umqobo wokufuma kunye nokuchasana nokubanda kuphuculwe kakhulu ngenxa yokuqhelaniswa neemolekyuli ezoluliweyo.
Iipropati zefilimu yeBOPP:
Amandla aphezulu, imodyuli ephezulu yokuqina, kodwa amandla aphantsi okukrazula; ukuqina okulungileyo, ubude obubalaseleyo kunye nokuchasana nokugoba ukusebenza kokudinwa; ubushushu kunye nokumelana nokubanda kuphezulu, ukusetyenziswa kobushushu ukuya kuthi ga kwi-120 ℃, ukumelana nokubanda kwe-BOPP kuphezulu kunefilimu yePP jikelele; isicwebezelisi somgangatho ophezulu, ukucaca kakuhle, okufanelekileyo kwizinto ezahlukeneyo zokupakisha; I-BOPP ukuzinza kweekhemikhali kulungile, ngaphezu kwee-acids ezinamandla, ezifana ne-fuming sulfuric acid, i-nitric acid inefuthe elibi kuyo Ukongeza, ayinyibiliki kwezinye i-solvents, kwaye kuphela i-hydrocarbons ethile inomphumela wokuvuvukala kuyo; ukuxhathisa okugqwesileyo kwamanzi, enye yezona zinto zibalaseleyo zokufuma kunye nokuxhathisa ukufuma, izinga lokufunxa amanzi <0.01%; ukungashicileli kakuhle, ngoko ke umphezulu kufuneka uphathwe nge-corona phambi koshicilelo, isiphumo esihle soshicilelo emva kokucubungula; umbane ophezulu we-static, i-resin esetyenziselwa ukuveliswa kwefilimu kufuneka ifakwe kwi-agent ye-antistatic.
2, Matte BOPP
Uluhlu olungaphezulu lwe-matte BOPP luyilwe njengoluhlu lwe-matte, elenza ukubonakala kwesicatshulwa kufana nephepha kunye nokukhululeka kwi-touch. I-matte surface layer ayisetyenziselwanga ukutywinwa kobushushu, ngenxa yobukho be-matte layer, xa kuthelekiswa ne-BOPP yenjongo jikelele, inezi mpawu zilandelayo: umaleko we-matte ungadlala indima yomthunzi, i-gloss ye-gloss nayo iyancipha kakhulu; umaleko we-matte ungasetyenziselwa ukutywinwa kobushushu xa kuyimfuneko; umaleko womphezulu we-matte ugudile kwaye ulungile, kuba umphezulu urhabaxa nge-anti-adhesive, imiqulu yefilimu ayilula ukunamathela; Amandla efilimu ye-matte angaphantsi kancinane kunefilimu yenjongo jikelele, uzinzo lwe-thermal lukwabizwa ngokuba yi-BOPP eqhelekileyo kancinane.
3, ifilimu yeperilescent
Ifilimu ye-pearlescent yenziwe ngePP, i-CaCO3, i-pigment ye-pearlescent kunye ne-rubber hood modifier yongezwa kwaye ixutywe kunye ne-bi-directional stretching. Njengoko ii-molecule ze-resin ze-PP zoluliwe ngexesha lenkqubo yokwelula i-biaxial, kunye neengqungquthela ze-CaCO3 zoluliwe ngaphandle komnye nomnye, ngaloo ndlela zenza ama-bubbles e-pore, ngoko ifilimu ye-pearlescent yifilimu ye-foam microporous kunye noxinaniso malunga ne-0.7g / cm³.
Imolekyuli ye-PP iphulukana nokutywinwa kobushushu emva kokuqhelaniswa ne-biaxial, kodwa isenotywinwa oluthile lobushushu njengerabha kunye nezinye izilungisi, kodwa amandla okutywinwa kobushushu aphantsi kakhulu kwaye kulula ukuwakrazula, ahlala esetyenziswa kwipakethe ye-ayisikrimu, ipopsicle, njl.
4, Ukutywinwa kobushushu befilimu yeBOPP
Ifilimu enamacala amabini etywinwe ubushushu:
Lo mboniso bhanyabhanya uyisakhiwo se-ABC, A kunye no-C amacala kumaleko wetywina lobushushu. Isetyenziswa kakhulu njengezinto zokupakisha ukutya, impahla, iaudio kunye neemveliso zevidiyo, njl.
Ifilim enecala elinye elitywina ubushushu:
Olu hlobo lwefilimu lulwakhiwo lwe-ABB, olunoMaleko njengomaleko wokutywina ubushushu. Emva kweepatheni zokushicilela kwicala le-B, i-laminated kunye ne-PE, i-BOPP kunye ne-aluminium foil ukwenza iingxowa, ezisetyenziselwa izinto zokupakisha eziphezulu zokutya, iziselo, iti, njl.
I-5, ifilimu ye-CPP elibazisiweyo
Ifilimu ye-CPP ye-polypropylene ye-Cast yifilimu ye-polypropylene engasoluliyo, engekho i-directional.
Ifilimu ye-CPP ibonakaliswe ngokungafihlisi okuphezulu, i-flatness elungileyo, ukumelana nobushushu obuphezulu, iqondo elithile lokuguquguquka ngaphandle kokulahlekelwa ukuguquguquka, iimpawu ezintle zokutywinwa kobushushu. I-Homopolymer CPP inoluhlu olumxinwa lobushushu bokutywinwa kobushushu kunye nokuqina okuphezulu, okwenza ukuba ilungele ukusetyenziswa njengefilimu yokupakisha yomaleko omnye.
I-co-polymer CPP inomsebenzi olinganiselayo kwaye ifanelekile njengoluhlu lwangaphakathi lwefilimu edibeneyo. Okwangoku, i-general i-co-extruded CPP, inokusebenzisa ngokupheleleyo iintlobo zeempawu ze-polypropylene zokudibanisa, okwenza ukusebenza kwe-CPP kubanzi.
6.Ifilimu ye-IPP evuthelweyo
Ifilimu evuthelweyo ye-IPP iveliswa ngokubanzi ngendlela yokuhla, i-PP ikhutshwe kwaye ivuthelwe kwi-ring die mouth, ngokukhawuleza emva kokupholisa kokuqala ngendandatho yomoya, emise ukupholisa okungxamisekileyo kwamanzi, omisiwe kunye nokuqengqeleka, imveliso egqityiweyo yifilimu ye-cylinder, enokuthi kwakhona isikwe ibe yifilim yeshiti. I-IPP evuthelweyo inokungafihli kakuhle, ukuqina okuhle kunye nokwenza ibhegi elula, kodwa ukufana kobukhulu bayo akulunganga kwaye ukucaba kwefilimu akulunganga.
