I-ATIKILI IZIKHOMBISI
1. Athini amagama efilimu ye-CPP, ifilimu ye-OPP, ifilimu ye-BOPP, nefilimu ye-MOPP?
2. Kungani ifilimu idinga ukunwetshwa?
3. Uyini umehluko phakathi kwefilimu ye-PP nefilimu ye-OPP?
4. Unjani umehluko phakathi kwe-OPPifilimu kanye ne-CPPifilimu?
5. Uyini umehluko phakathi kwefilimu ye-OPP, ifilimu ye-BOPP, nefilimu ye-MOPP?
1. Athini amagama efilimu ye-CPP, ifilimu ye-OPP, ifilimu ye-BOPP, nefilimu ye-MOPP?
Ifilimu ye-PP ibhekisela egameni elivamile elithi "ifilimu ye-polypropylene", Ngokusebenzisa izindlela ezahlukene zokukhiqiza, amafilimu e-PP anezici ezihlukene ayakhiqizwa,Futhi asetshenziswe emikhakheni ehlukene, futhi anwetshelwe kwamanye amagama, Amagama avamile avamile yilawa:I-CPPifilimu, I-OPPifilimu, I-BOPPifilimu, I-MOPPifilimu, Lawa magama amane wonke enziwe ngefilimu ye-PP, ekhiqizwa kusetshenziswa izinto zokusetshenziswa zepulasitiki ze-PP ngemishini yokukhipha,Amagama ahlukene avele ngezinqubo ezahlukene "zokwelula ifilimu".
Okulandelayo okumakwe ngokubomvu kubonisa umehluko "kwindlela yokwelula ifilimu"
1. C Ifilimu ye-PP: isifinyezo seC st Polypropylene,
Igama "phonsa ifilimu ye-polypropylene" ibhekisela entweni enganwebeki,okungaqondile ifilimu flat extruded.
2. OIfilimu ye-PP: Isifinyezo seIqondiswe Polypropylene,
Okusho ukuthi,'ukwelula unidirectionalyefilimu ye-polypropylene', kuTD inkomba yokwelula unidirectional.
3. BO Ifilimu ye-PP: isifinyezo seI-Biaxially OrientedPolypropylene,
Okusho ukuthi "i-biaxially yeluliwe ifilimu ye-polypropylene", enwebeka ku-Izikhombisi-ndlela ze-MD ne-TD.
4. MO Ifilimu ye-PP: isifinyezo seI-Monoaxially OrientedPolypropylene,
Okusho ukuthi,'unidirectional weluliwe ifilimu ye-polypropylene', i-unidirectional enwetshiwe ku-MD isiqondiso.
▶Isiqondiso se-MD: Ibhekisela ku-ManeDirection, okuyisiqondiso se-longitudinal sefilimu.
▶Isiqondiso se-TD: Ibhekisela ku-Ti-ransverseDukulungiswa kwefilimu.
2.Kungani ifilimu idinga ukwelulwa?
Ngokuvamile, isizathu sokuthi kungani ifilimu yepulasitiki idinga "okweluliwe" kwenzelwe lezi zinhloso ezilandelayo:
1. Thuthukisa ukuzinza kwe-dimensional.
2. Thuthukisa izakhiwo zemishini.
3. Thuthukisa ukucwebezela nokungafihli lutho.
4. Thuthukisa ukumelana komoya.
Amaphuzu amane angenhla yizizathu zokuthi kungani ifilimu idinga ukwelulwa,Ngenxa yokwelula kwe-polymer, ingakwazi ukuhlela isiqondiso esinwebekayo se-polymer ngendlela evamile, ikhiqize izinga eliphezulu lokusebenzisana, ithuthukise ukuminyana kwezinto ezibonakalayo namandla efilimu,ukwandisa ukumelana negesi, ukuthuthukisa izakhiwo zemishini, futhi kwandise ukucwebezela kwendawo nokungafihli.
3.Uyini umehluko phakathi kwefilimu ye-PP nefilimu ye-OPP?
Ifilimu ye-PP isho ifilimu ye-polypropylene, futhi ifilimu evame ukubizwa nge-PP ingase ibe ifilimu ye-CPP, ifilimu ye-BOPP, noma ifilimu ye-PP esebenzayo (ifilimu evikelayo ye-PP, ifilimu ekhanyayo ye-PP, ifilimu eyinhlanganisela ye-PP), ngakho ifilimu ye-PP iyitemu elibanzi kuphela.
Eqinisweni, kungase kube namafilimu e-PP anokusebenza okuhlukile noma izinqubo ezinwebekayo.
Ifilimu ye-OPP iwumkhiqizo wefilimu omncane osebenzisa "indlela yokwelula i-unidirectional" kufilimu ye-PP, evumela ifilimu ukuthi inwebeke endaweni ye-TD, okuholela ekubeni namandla angcono okubamba, ukucwebezela, ukumelana negesi, njll Ifaneleka kakhulu njengesikhwama sokupakisha umkhiqizo. noma itheyiphu esobala.
<Isiphetho>
Izinto zokusetshenziswa zefilimu ye-PP nefilimu ye-OPP zombili ziyi-polypropylene,
Ifilimu ye-PP yigama elijwayelekile lefilimu ye-polypropylene,
Ngemuva kokwelula ifilimu ye-PP ngomshini wokunweba we-TDO, kukhiqizwa ifilimu ye-OPP,
Futhi ifilimu ye-OPP ithuthukisa izakhiwo zemishini, iyenze ifanelekele ukusetshenziswa njengezikhwama zokupakisha namateyipu okunamathela.
4.Unjani umehluko phakathi kwefilimu ye-OPP nefilimu ye-CPP?
Ifilimu ye-CPP yaziwa nangokuthi i-polypropylene eyi-cast, eyaziwa nangokuthi ifilimu ye-polypropylene enganwetshiwe.
Ipulasitiki inyibilika ibe impahla eluhlaza nge-extruder, ikhishwe ngesikhunta sokubumba isakhiwo esimise okwe-T, sigeleza siyishidi singene kurola obandayo wokupholisa ngokushesha, bese siyadonswa, sinqunywe, futhi sigoqwe ukuze kuqedelwe umkhiqizo.
Ngenxa yale nqubo, ulwelwesi lwe-CPP lunezici ezimbalwa:
-Ukuqina okuphezulu kunefilimu ye-PE.
-Isithiyo esihle kakhulu somswakama kanye nephunga.
-Ukuhlanganiswa okwenziwe ngokwezifiso ukukhiqiza ulwelwesi olusebenzayo.
-Awekho ama-solvents asetshenziswayo ngesikhathi sokukhiqiza, okuhambisana nemvelo.
-Ngokulula, amandla aphezulu, ukuqina okuphezulu, nokumelana nomthelela omuhle kakhulu, kuyisinqumo esikhethwayo sezinto eziyinhlanganisela.
<Isiphetho>
Umehluko omkhulu phakathi kwefilimu ye-CPP nefilimu ye-OPP ukuthi ifilimu inwetshiwe noma cha. I-OPP isebenzisa ubuchwepheshe bokwelula ukuthuthukisa ukusebenza kwefilimu. Nakuba ifilimu ye-CPP ingeluliwe, ifomula ingalungiswa ngokuvumelana nezidingo zamakhasimende, okwenza ukusetshenziswa kwayo kwande futhi kushintshe kakhulu.
Isibonelo, ukushintsha umbala, indawo yenkungu, indawo ekhanyayo, i-anti fog, ukuphrinta, njll. yefilimu Amafilimu ahlukahlukene asebenzayo e-PP angakhiqizwa ngokusebenzisa amafomula ahlukene.
5.Yimuphi umehluko phakathi kwefilimu ye-OPP, ifilimu ye-BOPP, nefilimu ye-MOPP?
Ifilimu ye-BOPP ifilimu ye-polypropylene enwetshiwe nge-biaxially
Ifilimu ye-OPP ifilimu ye-polypropylene enwetshiwe kamuva
Ifilimu ye-MOPP ifilimu ye-polypropylene enwetshiwe isikhathi eside
Sizoxoxa ngemibuzo evame ukubuzwa "yefilimu ye-OPP iqhudelana nefilimu ye-BOPP" kanye "nefilimu ye-OPP iqhudelana nefilimu ye-MOPP":
a. Uyini umehluko phakathi kwefilimu ye-OPP nefilimu ye-BOPP?
Izakhiwo ezingokoqobo nezici ze-OPP kanye ne-BOPP membranes azihlukile kakhulu ngaphansi kwezimo zangempela zokusetshenziswa, futhi ziphathwa njengolwelwesi olufanayo. Njengoba i-OPP ikhiqizwa i-extruder, i-membrane isivele yeluliwe ngobude (isiqondiso se-MD) ngesikhathi senqubo yokukhiqiza,abese ngokuvundlile (TD direction) ngomshini wokunweba. Yonke le nqubo isesimweni "sokwelula kwe-biaxial", ngakho-ke imiphumela ifana naleyo ye-BOPP membrane biaxial stretching usebenzisa umshini wokunweba we-biaxial, Ngakho-ke, awukho umehluko ophawulekayo ezicini phakathi kwefilimu ye-OPP nefilimu ye-BOPP.
Izindlela zokwelula unidirectional kanye nokwelula kwe-biaxial, uma zisetshenziswa ku-PET noma izinto ze-PC, zizokhiqiza izici ezihlukile,
Kunomehluko omkhulu ekusebenzeni kokubona noma inkomba ye-refractive phakathi kwe-PET ne-BOPET. Kodwa uma isetshenziswa kufilimu ye-PP, umehluko mncane kakhulu.
b. Uyini umehluko phakathi kwefilimu ye-OPP nefilimu ye-MOPP?
Ifilimu ye-OPP inweba "Ngokuhamba kwesikhathi kweifilimu", kuyilapho ifilimu ye-MOPP inweba "ngobude be-fim". Uma ifilimu ye-MOPP inweba ngobude, inweba "ngokuhamba kwewashi" yeketango lamangqamuzana, ngakho-ke amandla e-longitudinal tensile anamandla, kodwa amandla ashubile aphambene abuthakathaka, okwenza kube lula ukuphuka.
Ifilimu ye-OPP, ngenxa yezakhiwo zayo ezifanayo nefilimu ye-BOPP okukhulunywe ngayo ngenhla, ayijwayele ukuphuka kuzo zombili izikhombisi-ndlela ze-longitudinal ne-transverse futhi inamandla ayisisekelo okuqinile.
<Isiphetho>
a. Uyini umehluko phakathi kwefilimu ye-OPP nefilimu ye-BOPP?
Ngokombono wamasu okukhiqiza, lezi ezimbili ziyimikhiqizo ekhiqizwa ngamasu ahlukene.
Ngokombono wesicelo, lezi ezimbili zibhekwa njengomkhiqizo ofanayo ngoba umehluko wezimpawu mncane kakhulu.
b. Uyini umehluko phakathi kwefilimu ye-OPP nefilimu ye-MOPP?
Amandla we-longitudinal tensile we-membrane: ulwelwesi lwe-MOPP> ulwelwesi lwe-OPP
Ngakho-ke, ifilimu ye-MOPP ifaneleka izinhlelo zokusebenza ezinezakhiwo ezingaqondile kanye namandla aphezulu okuqina.
Ifilimu ye-OPP inamandla athile ayisisekelo okuqinile kuzo zombili izikhombisi-ndlela ze-longitudinal neziphambene.
Okungenhla ukuhlanganiswa nokwabelana kwezincwadi eziku-inthanethi,Uma unezidingo zokuthenga zefilimu ye-CPP, ifilimu ye-OPP, ifilimu ye-BOPP, ifilimu ye-MOPP, sicela usithinte:
