Filimu ya polypropylene cast (CPP film) ndi mtundu wa filimu yopanda kufalikira yopangidwa ndi njira yopangira, yomwe ili ndi mawonekedwe owonekera bwino, kuwala kwambiri, kusalala bwino, kutseka kosavuta kutentha, ndi zina zotero. Pamwamba pake pangagwiritsidwe ntchito popanga aluminiyamu, kusindikiza, kuphatikiza, ndi zina zotero pambuyo pa chithandizo cha corona, kotero imagwiritsidwa ntchito kwambiri poyika zakudya, zofunikira za tsiku ndi tsiku, zinthu zamagetsi ndi zina zotero.

Chimodzi mwa makhalidwe a filimu ya CPP ndi kuwonekera bwino kwake, ndipo magwiridwe ake amakhudza mwachindunji mtundu wa ma CD. Zinthu zomwe zimakhudza kuwonekera bwino kwa filimu ya CPP zili ndi magulu awiri akuluakulu: kapangidwe ndi njira yopangira. Kupanga kumaphatikizapo zinthu zazikulu ndi zinthu zothandizira; njira yopangira: kutentha kosungunuka ndi kutentha kwa roller yozizira, kusiyana kwa milomo ya die, kutalika kwa kusiyana kwa mpweya (monga, mtunda pakati pa milomo ya die ndi roller yozizira), vacuum box vacuum, kuchuluka kwa mpweya wa bokosi la mpweya, ndi zina zotero.

Mphamvu ya zinthu zazikulu pa kuwonekera bwino kwa filimu ya polypropylene cast CPP

Zipangizo zazikulu za filimu ya CPP nthawi zambiri zimagwiritsidwa ntchito pa kusungunuka kwa 6 ~ 12g/10min resin, yogawidwa mu homopolymer PP, binary copolymer PP, terpolymer PP, nthawi zambiri, kuwonekera bwino kwa copolymer PP kuli bwino kuposa homopolymer, koma kuuma kwa homopolymer PP kuli bwino kuposa copolymer, ndipo homopolymer PP ilibe kutentha kotseka, copolymer PP ili ndi mawonekedwe abwino otsekera, makamaka terpolymer PP, yokhala ndi kutentha kotseka kotsika. Copolymer PP ili ndi kutentha kotseka bwino, makamaka ternary copolymer PP, ili ndi kutentha kotsika kotseka bwino, momwe ingagwirizanire malinga ndi zofunikira za filimuyi.

Zotsatira za zipangizo zothandizira pa kuwonekera bwino kwa filimu ya polypropylene cast CPP

Zipangizo zothandizira za filimu ya CPP zimaphatikizapo choletsa kutsekeka/chotsekera, chotchingira kutsetsereka, chotchingira kukhazikika, ndi zina zotero. Gawo lalikulu la chotchingira kutsekeka ndi silica. Gawo lalikulu la chotchingira kutsekeka ndi silicon dioxide, ndikoyenera kugwiritsa ntchito silicon dioxide yopangidwa, tinthu take ndi tosalala, tofanana, ndipo timakhudza pang'ono kuwonekera bwino kwa filimuyo; chotchingira chosalala, chotchingira kukhazikika kosalala, kuwonjezera kuchuluka koyenera kwa chotchingira chosalala, chotchingira kukhazikika, kukonza kusalala ndi mphamvu zotsutsana ndi kukhazikika nthawi imodzi, ndikothandiza kukonza kunyezimira kwa filimuyo, komwe kumathandiza kukonza kuwonekera bwino.

Zotsatira za zowonjezera za amide pakuwonekera bwino kwa filimu ya polypropylene cast CPP

Zinthu zodziwika bwino zothira filimu ndi ma amide: Ntchito yayikulu ya zowonjezera za amide (erucic acid amides, oleic acid amides, ndi zina zotero) popanga mafilimu a polyolefin ndikupatsa mphamvu zothira. Kuwonjezera kwa chinthu chothira filimucho kumagwira ntchito ngati chosungiramo mafuta opangidwa mkati mwa polymer matrix, chomwe chimasamuka kupita pamwamba pa filimu ya polymer nthawi yomweyo atachoka mu nkhungu. Mafuta a amide amasungunuka mu kusungunuka kosasinthika panthawi yokonza, koma pamene polymer ikuzizira ndikuyamba kupangika, chinthu chothira chimatulutsidwa kuchokera ku polymer matrix yolimba. Imafika pamwamba ndikupanga gawo lopaka mafuta, zomwe zimapangitsa kuti pamwamba pake pakhale posalala.

Komabe, chifukwa cha kapangidwe kake, mawonekedwe ake komanso kulemera kochepa kwa mamolekyu azinthu zosinthira mafilimu (ma amides), ndizosavuta kuziyika kapena kuzipanga ufa, ndipo ngati ziwonjezeredwa mopitirira muyeso, chifunga chidzapangidwa pamwamba pa filimuyo chifukwa cha kuchuluka kwawo kwa kutuluka, zomwe zimapangitsa kuti kuwonekera kuchepe. Nthawi yomweyo, chifukwa cha kufalikira kosagwirizana kwa filimuyo, mizere yopingasa kapena yowongoka imawonekera, ndipo imachepetsa kwambiri mphamvu ya talcum agent, coefficient of friction idzakhala yosakhazikika chifukwa cha kutentha kosiyanasiyana, kufunikira koyeretsa screw nthawi zonse, ndipo kungayambitse kuwonongeka kwa zida ndi zinthu. Pokonza filimu yophulika, ufa woyera umakhazikika mosavuta pamwamba pa filimuyo chifukwa cha kusamuka kwa slip agent pamwamba pake, ndipo ndikosavuta kusiya ufa pa ma rollers.

Mndandanda wa SILIMER wa zinthu zotsitsira filimu zomwe sizimagwa mvulaAli ndi kukhazikika kwakukulu ndipo sikophweka kukhazikika, ndipo nthawi yomweyo, samakhudza kutseka kutentha kwa filimu ndi laminating, samakhudza kusindikiza, ndipo ali ndi ma coefficients okhazikika a kukangana. Ndi oyenera kupanga filimu ya pulasitiki, zida zomangira chakudya, kupanga zida zomangira mankhwala, ndi zina zotero.

SILIKEMndandanda wa SILIMER Osasamukira Zowonjezera za Slip ndi Anti-Block Film, Sizimakhudza kuwonekera bwino kwa filimu ya CPP polypropylene.

SILIKE non-precipitation slip agent masterbatch SILIMER 5065, SILIMER 5065HB ndi super-slip masterbatch yokhala ndi unyolo wautali wa alkyl-modified siloxane masterbatch yokhala ndi antiblock additive. Imagwiritsidwa ntchito kwambiri m'mafilimu a CPP, ma oriented flat film applications ndi zinthu zina zogwirizana ndi polypropylene. Ikhoza kusintha kwambiri anti-blocking & fascia ya filimu, ndipo mafuta odzola panthawi yokonza, amatha kuchepetsa kwambiri dynamic surface dynamic and static friction coefficient, ndikupangitsa kuti pamwamba pa filimuyo pakhale posalala.

Nthawi yomweyo, SILIKE Novel super-migratory super-slip & Anti-blocking agent SILIMER 5065HB ili ndi kapangidwe kapadera komwe kamagwirizana bwino ndi matrix resin, palibe mvula, palibe kumatira, komanso palibe chomwe chimakhudza kuwonekera bwino kwa filimu.
