1. Ngawaphi amagama efilimu ye-CPP, ifilimu ye-OPP, ifilimu ye-BOPP, kunye nefilimu ye-MOPP?
Ifilimu ye-PP ibhekisa kwigama eliqhelekileyo elithi "ifilimu ye-polypropylene", Ngokusebenzisa iindlela ezahlukeneyo zokuvelisa, iifilimu zePP ezineempawu ezahlukeneyo ziyaveliswa, kwaye zisetyenziswe kwiinkalo ezahlukeneyo, kwaye zandiswe kwamanye amagama, Amagama aqhelekileyo aqhelekileyo ngala:CPPifilimu, OPPifilimu, I-BOPPifilimu, MOPPifilimuLa magama mane enziwe ngefilimu yePP, eveliswa kusetyenziswa izixhobo zeplastiki zePP ngoomatshini bokukhupha,Amagama ahlukeneyo avele ngeenkqubo ezahlukeneyo "zokolula ifilimu".
Oku kulandelayo kuphawulwe ngobomvu kubonisa umahluko "kwindlela yokwelula ifilimu"
1. C Ifilimu yePP: isifinyezo seC st Polypropylene,
Igama elithile "phosa ifilimu ye-polypropylene" ibhekisa kwinto engenakunwebeka,engaqhelanga ifilimu ethe tyaba ekhutshiweyo.
2. OIfilimu yePP: Ufinyezo lweUkuqhelaniswa Polypropylene,
Oko kukuthi,'ukolula unidirectionalyefilimu yepolypropylene', kwiUlwalathiso lweTD Ukolula okukodwa.
3. BO Ifilimu yePP: isifinyezo seI-Biaxially OrientedPolypropylene,
Nditsho"i-biaxially yoluliwe ifilimu ye-polypropylene", eyolula kwiMD kunye ne-TD imiyalelo.
4. MO Ifilimu yePP: isifinyezo seI-Monoaxially OrientedPolypropylene,
Oko kukuthi,'unidirectional yoluliwe ifilimu ye-polypropylene', i-unidirectional yoluliwe kwiMD ulwalathiso.
▶Isalathiso seMD: Ibhekisa kwiMhayiDirection, eyindlela yobude befilimu.
▶Isalathiso seTD: Ibhekisa kwiTransverseDukulungiswa kwefilimu.
2.Kutheni ifilimu kufuneka yolulwe?
Ngokuqhelekileyo, isizathu sokuba ifilimu yeplastiki ifuneke "oluliweyo" kwenzelwa ezi njongo zilandelayo:
1. Ukuphucula uzinzo lwe-dimensional.
2. Ukuphucula iimpawu zoomatshini.
3. Ukuphucula ukumenyezela kunye nokungafihli.
4. Ukuphucula ukumelana nomoya.
Ezi ngongoma zine zingentla zizizathu zokuba ifilimu kufuneka yolulwe,Ngenxa yokolulwa kwepolymer, inokulungelelanisa indlela eyolulayo yepolymer ngendlela eqhelekileyo, ivelise inqanaba eliphezulu lokulungelelanisa, iphucule ukuxinana kwezinto kunye namandla efilimu,ukwandisa ukumelana negesi, ukuphucula iimpawu zoomatshini, kunye nokwandisa ukucwebezela komphezulu kunye nokungafihli.
3.Uthini umahluko phakathi kwefilimu yePP kunye nefilimu ye-OPP?
Ifilimu ye-PP ibhekisela kwifilimu ye-polypropylene, kwaye ngokuqhelekileyo ifilimu ye-PP ingaba yifilimu ye-CPP, ifilimu ye-BOPP, okanye ifilimu ye-PP esebenzayo (ifilimu ekhuselayo ye-PP, ifilimu ekhanyayo ye-PP, ifilimu ye-PP edibeneyo), ngoko ifilimu ye-PP lixesha elibanzi kuphela.
Enyanisweni, kunokubakho iifilimu zePP ezinomsebenzi ohlukeneyo okanye iinkqubo zokwelula.
Ifilimu ye-OPP yimveliso yefilimu ebhityileyo esebenzisa "indlela yokwelula i-unidirectional" kwifilimu ye-PP, evumela ifilimu ukuba yandise kwicala le-TD, ibangele amandla angcono okuqina, ukukhanya, ukuchasana kwegesi, njl. okanye iteyiphu ecacileyo.
<Ukuqukumbela>
Izinto ezikrwada zefilimu yePP kunye nefilimu ye-OPP zombini ziyi-polypropylene,
Ifilimu yePP ligama nje eliqhelekileyo lefilimu yepolypropylene,
Emva kokwelula ifilimu ye-PP ngomatshini wokwandiswa kwe-TDO, iveliswa ifilimu ye-OPP,
Kwaye ifilimu ye-OPP iphucula iipropathi zoomatshini, iyenza ilungele ukusetyenziswa njengeengxowa zokupakisha kunye neeteyiphu zokuncamathelisa.
4.Unjani umahluko phakathi kwefilimu ye-OPP kunye nefilimu ye-CPP?
Ifilimu ye-CPP ikwabizwa ngokuba yi-polypropylene ephosiweyo, ekwabizwa ngokuba yifilimu yepolypropylene engolulwanga.
Iplastiki inyibilika kwisixhobo ekrwada ngokusebenzisa i-extruder, ikhutshwe nge-T-shaped structure mold mold, igeleza kwi-sheet shape kwi-roller yokuphosa ebandayo yokupholisa ngokukhawuleza, emva koko itsalwe, ilungiswe, kwaye iqengqeleke ukuze igqibe imveliso.
Ngenxa yale nkqubo, iimbrane zeCPP zineempawu ezininzi:
-Ukuqina okuphezulu kunefilimu ye-PE.
-Umqobo ogqwesileyo wokufuma kunye nevumba.
-Ukudibanisa ngokwezifiso ukuvelisa ii-membrane ezisebenzayo.
-Azikho izinyibilikisi ezisetyenziswayo ngexesha lenkqubo yokuvelisa, ehambelana nokusingqongileyo.
-Ngobunzima obukhaphukhaphu, amandla aphezulu, ukuqina okuphezulu, kunye nokuchasana okugqwesileyo kwempembelelo, lukhetho olukhethiweyo lwezixhobo ezidibeneyo.
<Ukuqukumbela>
Umahluko omkhulu phakathi kwefilimu yeCPP kunye nefilimu ye-OPP kukuba ingaba ifilimu yoluliwe okanye ayikho. I-OPP isebenzisa itekhnoloji eyolulayo ukuphucula ukusebenza kwefilimu. Nangona ifilimu ye-CPP ingoluliwe, ifomula inokulungelelaniswa ngokweemfuno zabathengi, okwenza isicelo sayo sisasazeke kwaye sitshintshe ngakumbi.
Umzekelo, ukutshintsha umbala, umphezulu wenkungu, umphezulu oqaqambileyo, inkungu echasayo, ushicilelo, njl. njl
5.Nguwuphi umahluko phakathi kwefilimu ye-OPP, ifilimu yeBOPP, kunye nefilimu ye-MOPP?
Ifilimu yeBOPP yifilimu yepolypropylene eyoluliweyo yebiaxially
Ifilimu ye-OPP yifilimu yepolypropylene eyoluliweyo
Ifilimu ye-MOPP yifilimu yepolypropylene eyolulwe ixesha elide
Siza kuxoxa ngeyona mibuzo ixhaphakileyo ebuzwa "yefilimu ye-OPP vs. ifilimu ye-BOPP" kunye "nefilimu ye-OPP vs. ifilimu ye-MOPP":
a. Yintoni umahluko phakathi kwefilimu ye-OPP kunye nefilimu yeBOPP?
Iimpawu zomzimba kunye neempawu ze-OPP kunye ne-BOPP membranes azahlukanga kakhulu phantsi kweemeko zokusetyenziswa, kwaye ziphathwa njenge-membrane efanayo. Njengoko i-OPP iveliswa yi-extruder, i-membrane sele yoluliwe ixesha elide (i-MD direction) ngexesha lenkqubo yokuvelisa,akwaye emva koko ngokuthe tye (TD direction) ngomatshini wokwandisa. Yonke inkqubo ikwimo ye "biaxial stretching", ngoko ke iziphumo zifana nezo zeBOPP membrane biaxial stretching usebenzisa umatshini wokwandisa i-biaxial, Ngoko ke, akukho mahluko abalulekileyo kwiimpawu phakathi kwefilimu ye-OPP kunye nefilimu ye-BOPP.
Iindlela zokwelula unidirectional kunye ne-biaxial stretching, ukuba zisetyenziswe kwi-PET okanye kwi-PC izinto, ziya kuvelisa iimpawu ezahlukeneyo,
Kukho umehluko omkhulu ekusebenzeni kwe-optical okanye i-index refractive phakathi kwe-PET kunye ne-BOPET. Kodwa xa isetyenziswa kwifilimu yePP, umahluko uncinci.
b. Yintoni umahluko phakathi kwefilimu ye-OPP kunye nefilimu ye-MOPP?
Ifilimu ye-OPP yandisa "Emva kwexesha leifilimu", ngelixa ifilimu ye-MOPP yandisa "ixesha elide leifim". Xa ifilimu ye-MOPP ithatha ixesha elide, iyolula "ixesha lexesha" kwitsheyina le-molecular, ngoko ke amandla e-longitudinal tensile yomelele, kodwa amandla okuqina anqamlezayo abuthathaka, okwenza kube lula ukuphuka.
Ifilimu ye-OPP, ngenxa yeepropathi zayo ezifanayo nefilimu ye-BOPP ekhankanywe ngasentla, ayinako ukwaphuka kuzo zombini izikhokelo ze-longitudinal kunye ne-transverse kwaye inamandla asisiseko.

a. Yintoni umahluko phakathi kwefilimu ye-OPP kunye nefilimu yeBOPP?
Ngokombono weendlela zokuvelisa, ezi zimbini ziyimveliso eveliswa ngeendlela ezahlukeneyo.
Ngokombono wesicelo, ezi zimbini zithathwa njengemveliso efanayo kuba ukungafani kweempawu kuncinci kakhulu.
b. Yintoni umahluko phakathi kwefilimu ye-OPP kunye nefilimu ye-MOPP?
Amandla e-longitudinal tensile ye-membrane: i-MOPP membrane> i-OPP inwebu
Ke ngoko, ifilimu ye-MOPP ifanelekile kwizicelo ezineempawu ezingafaniyo kunye namandla aphezulu.
Ifilimu ye-OPP inamandla athile asisiseko kwi-longitudinal kunye ne-transverse directions.
Oku kungasentla kukuqulunqa kunye nokwabelana ngoncwadi olukwi-intanethi, ukuba uneemfuno zokuthenga ifilimu ye-CPP, ifilimu ye-OPP, ifilimu ye-BOPP, ifilimu ye-MOPP, nceda uqhagamshelane nathi:
