Litšobotsi tsa ts'ebetso ea lifilimi tse kholo tsa polasetiki:
Filimi ea Biaxially Oriented Polypropylene (BOPP)
Polypropylene ke resin ea thermoplastic e hlahisoang ke polymerization ea propylene. Lisebelisoa tsa Copolymer PP li na le mocheso o fokolang oa mocheso (100 ° C), pepeneneng e tlase, botlolo bo tlase, le ho tiea ho tlase, empa li na le matla a matla a ts'usumetso, 'me matla a ts'usumetso ea PP a eketseha ka keketseho ea litaba tsa ethylene. Thempereichara e bonolo ea Vicat ea PP ke 150 ° C. Ka lebaka la tekanyo e phahameng ea crystallinity, thepa ena e na le ho satalla hantle holimo holimo le thepa ea ho hanyetsa mohatla. PP ha e na mathata a khatello ea tikoloho.
Biaxially oriented polypropylene film (BOPP) ke sesebelisoa sa sephutheloana se pepeneneng se ntlafalitsoeng ka bo-1960. E sebelisa mohala o khethehileng oa tlhahiso ho kopanya lisebelisoa tse tala tsa polypropylene le li-additives tse sebetsang, ho qhibiliha le ho li kopanya ka maqephe, ebe o li otlolla lifiliming. E sebelisoa haholo ho paka lijo, lipompong, lisakerete, tee, lero, lebese, masela, joalo-joalo, 'me e na le botumo ba "Packaging Queen". Ntle le moo, e ka boela ea sebelisoa ho lokiseng lihlahisoa tsa boleng bo phahameng tse kenyellelitsoeng tse sebetsang joalo ka li-membrane tsa motlakase le li-membrane tsa microporous, kahoo litebello tsa nts'etsopele ea lifilimi tsa BOPP li pharalletse haholo.
Filimi ea BOPP ha e na feela melemo ea ho fokotseha ho fokolang, ho hanyetsa kutu e ntle le ho hanyetsa mocheso o motle oa PP resin, empa hape e na le thepa e ntle ea optical, matla a phahameng a mochine le mehloli e mengata ea lihlahisoa tse tala. Filimi ea BOPP e ka kopanngoa le lisebelisoa tse ling tse nang le thepa e khethehileng ho ntlafatsa kapa ho ntlafatsa ts'ebetso. Lisebelisoa tse sebelisoang ka tloaelo li kenyelletsa filimi ea PE, filimi ea salivating polypropylene (CPP), polyvinylidene chloride (PVDC), filimi ea aluminium, joalo-joalo.
Filimi ea Polyethylene e Tlase (LDPE)
Filimi ea polyethylene, e leng PE, e na le litšobotsi tsa ho hanyetsa mongobo le ho fokotseha ha mongobo.
Low-density polyethylene (LPDE) ke resin ea maiketsetso e fumanoang ke ethylene radical polymerization tlas'a khatello e phahameng, kahoo e boetse e bitsoa "polyethylene e phahameng". LPDE ke molek'hule e nang le makala e nang le makala a bolelele bo fapaneng ketane e kholo, e nang le makala a ka bang 15 ho isa ho a 30 a ethyl, butyl kapa a malelele ho athomo ea khabone e 1000 ka ketane e kholo. Hobane ketane ea limolek'hule e na le liketane tse telele le tse khutšoane tse nang le makala, sehlahisoa se na le letsoalo le tlase, bonolo, ho hanyetsa mocheso o tlase, ho hanyetsa phello e ntle, botsitso ba lik'hemik'hale, 'me ka kakaretso ho hanyetsa acid (ntle le li-acid tse matla tsa oxidizing), Alkali, corrosion ea letsoai, e na le molemo. thepa ea ho kenya motlakase. E feto-fetoha ebile e benya, e na le botsitso bo botle ba lik'hemik'hale, ho tiiseha ha mocheso, ho hanyetsa metsi le ho hanyetsa mongobo, ho hanyetsa leqhoa, 'me e ka belisoa. Bothata ba eona bo ka sehloohong ke tšitiso ea eona e mpe ho oksijene.
Hangata e sebelisoa e le filimi ea ka hare ea lisebelisoa tsa ho paka tse feto-fetohang, hape ke filimi ea polasetiki e sebelisoang ka ho fetisisa le e sebelisoang ka ho fetisisa hajoale, e ikarabellang ho feta 40% ea tšebeliso ea lifilimi tsa polasetiki tsa polasetiki. Ho na le mefuta e mengata ea lifilimi tsa liphutheloana tsa polyethylene, 'me litšoantšiso tsa tsona li fapane. Ts'ebetso ea filimi ea lera le le leng e le 'ngoe,' me ts'ebetso ea filimi e kopantsoeng e tlatselletsana. Ke thepa e ka sehloohong ea ho paka lijo. Taba ea bobeli, filimi ea polyethylene e boetse e sebelisoa lefapheng la boenjiniere ba sechaba, joalo ka geomembrane. E sebetsa joalo ka ha e sa kenelle metsi ho boenjiniere ba sechaba mme e na le matla a tlase haholo. Filimi ea temo e sebelisoa temong, e ka aroloa ka filimi e tšolotsoeng, filimi ea mulch, filimi e bohloko ea sekoahelo, filimi ea polokelo e tala joalo-joalo.
Filimi ea polyester (PET)
Filimi ea polyester (PET), eo hangata e tsejoang e le polyethylene terephthalate, ke polasetiki ea boenjiniere ea thermoplastic. Ke thepa ea filimi e entsoeng ka maqephe a teteaneng ka extrusion ebe e otlolloa ka biaxially. Filimi ea polyester e khetholloa ka thepa e babatsehang ea mechine, ho tiea ho hoholo, ho thatafala le ho tiea, ho hanyetsa ho phunya, ho hanyetsa ho ferekanngoa, mocheso o phahameng le ho hanyetsa mocheso o tlaase, lik'hemik'hale tsa lik'hemik'hale, ho hanyetsa oli, ho thibela moea le ho boloka monko o monate. E 'ngoe ea li-substrates tsa filimi tse sa feleng, empa khanyetso ea corona ha e ntle.
Theko ea filimi ea polyester e batla e phahame, 'me botenya ba eona ka kakaretso ke 0.12 mm. Hangata e sebelisoa e le thepa ea ka ntle ea ho paka lijo bakeng sa ho paka, 'me e na le khatiso e ntle. Ho feta moo, filimi ea polyester e atisa ho sebelisoa e le lisebelisoa tsa khatiso le ho paka tse kang filimi ea tšireletso ea tikoloho, filimi ea PET, le filimi e tšoeu ea milky, 'me e sebelisoa haholo liindastering tse kang lipolasetiki tse matlafalitsoeng ka khalase, thepa ea mohaho, khatiso, meriana le bophelo bo botle.
Filimi ea polasetiki ea nylon (ONY)
Lebitso la lik'hemik'hale la nylon ke polyamide (PA). Hona joale, ho na le mefuta e mengata ea nylon e hlahisoang indastering, 'me mefuta e ka sehloohong e sebelisetsoang ho hlahisa lifilimi ke nylon 6, nylon 12, nylon 66, joalo-joalo Filimi ea nylon ke filimi e thata haholo e nang le pepenene e ntle, e khanyang, e nang le matla a phahameng le matla a phahameng. matla a tsitsipano, le ho hanyetsa mocheso o motle, ho hanyetsa serame, ho hanyetsa oli le ho hanyetsa ho qhibiliha ha lintho tse phelang. E ntle ka ho fetesisa le ho hanyetsa ho phunya, e batlang e le bonolo, e ntle haholo, thepa e ntle ea oksijene e thibelang mouoane oa metsi, ho monya mongobo o phahameng le ho kenella ha mongobo, mocheso o fokolang oa mocheso, o loketseng ho paka lintho tse thata, joalo ka lijo tse mafura tsa thobalano, lihlahisoa tsa nama, tse halikiloeng. lijo, lijo tse phuthetsoeng ka vacuum, lijo tse halikiloeng, joalo-joalo.
Filimi ea Cast Polypropylene (CPP)
Ho fapana le ts'ebetso ea biaxially oriented polypropylene film (BOPP), filimi ea cast polypropylene (CPP) ke filimi ea extrusion e sa otlolleheng, e sa shebaneng le e hlahisoang ke ho lahla le ho tima. E khetholloa ka lebelo la tlhahiso e potlakileng, tlhahiso e phahameng, pepeneneng e ntle ea filimi, gloss, ho lekana ha botenya, le ho leka-lekana ho babatsehang ha thepa e sa tšoaneng. Hobane ke filimi e pharalletseng e pharalletseng, mosebetsi oa ho latela joalo ka ho hatisa le ho kopanya o bonolo haholo. CPP e sebelisoa haholo ho paka masela, lipalesa, lijo le litlhoko tsa letsatsi le letsatsi.
Filimi ea polasetiki e entsoeng ka aluminium
Filimi ea aluminized e na le litšobotsi tse peli tsa filimi ea polasetiki le litšobotsi tsa tšepe. Karolo ea aluminium plating holim'a filimi ke ho sireletsa leseli le ho thibela mahlaseli a ultraviolet, a sa lelefatsang bophelo ba sethala sa litaba feela, empa hape a ntlafatsa khanya ea filimi. Ka hona, filimi ea aluminium e sebelisoa haholo ka har'a liphutheloana tse kopantsoeng, haholo-holo tse sebelisoang ka har'a liphutheloana tsa lijo tse omeletseng le tse bululetsoeng joalo ka libisikiti, hammoho le liphutheloana tsa kantle tsa meriana le litlolo.
