Letlapa la PLA
PLA ke mofuta oa line shape Aliphatic Polyesters.PLA e ka sebelisoa ka har'a sephutheloana se thata sa litholoana, meroho, mahe, lijo tse phehiloeng le lijo tse halikiloeng, hape e ka sebelisoa bakeng sa ho paka sandwich, libisikiti le liphutheloana tse ling tse kang palesa e ncha.
Tlhaloso ea Sehlahisoa
Polylactic acid (PLA) e ka senyeha ka ho feletseng hore e be carbon dioxide le metsi tlas'a maemo a tlhaho ka mor'a ho lahloa.E na le ho hanyetsa metsi hantle, thepa ea mechine, biocompatibility, e ka kenngoa ke lintho tse phelang, 'me ha e na tšilafalo ea tikoloho.Ka nako e ts'oanang, PLA e boetse e na le thepa e ntle ea mochini.E na le matla a ts'ebetso e phahameng, ho feto-fetoha ha maemo hantle le botsitso ba mocheso, polasetiki, ts'ebetso ea ts'ebetso, ha e feto-fetohe, e khona ho kenella hantle ho oksijene le mouoane oa metsi, le pepeneneng e ntle, anti-mildew, antibacterial, bophelo ba ts'ebeletso ke lilemo tse 2 ~ 3.

PLA e na le pepenene e ntle le e khanyang, 'me ts'ebetso ea eona e babatsehang e bapisoa le cellophane le PET, e sa fumaneheng ka li-plastiki tse ling tse senyehang.Ponaletso le khanya ea PLA ke makhetlo a 2 ~ 3 ho feta filimi e tloaelehileng ea PP le makhetlo a 10 ho feta a LDPE.Ponahalo ea eona e phahameng e etsa hore ponahalo ea ho sebelisa PLA e le thepa ea ho paka e be ntle.Ka mohlala, e sebelisetsoa ho kenya lipompong.Hajoale, liphutheloana tse ngata tsa lipompong 'marakeng li sebelisa lifilimi tsa ho paka tsa PLA.
Ponahalo le ts'ebetso ea filimi ena ea liphutheloana li tšoana le lifilimi tse tloaelehileng tsa lipompong tsa liphutheloana, tse nang le ponaletso e phahameng, ho boloka kink e babatsehang, ho hatisoa le matla, hammoho le thepa e babatsehang ea thibelo, e ka bolokang tatso ea lipompong hantle.Khampani ea Japane e sebelisa "racea" brand PLA ea American Cakir Dow Polymer Company e le thepa ea ho paka lihlahisoa tse ncha, 'me sephutheloana se hlakile haholo ka ponahalo.Toray Industries e thehile lifilimi le lilae tse sebetsang tsa PLA e sebelisa theknoloji ea eona ea nano-alloy.Filimi ena e na le mocheso o ts'oanang oa ho hanyetsa mocheso le tšusumetso joaloka lifilimi tse thehiloeng ho petroleum, empa hape e na le elasticity e babatsehang le pepeneneng.
PLA e ka etsoa lihlahisoa tsa lifilimi tse nang le pepenene e phahameng, thepa e ntle ea lithibelo, ts'ebetso e ntle haholo le thepa ea mochini, 'me e ka sebelisoa bakeng sa ho paka litholoana le meroho e bonolo.E ka etsa sebaka se loketseng sa polokelo bakeng sa litholoana le meroho, ho boloka mesebetsi ea bophelo ea litholoana le meroho, ho lieha ho tsofala, le ho boloka 'mala, monko, tatso le ponahalo ea litholoana le meroho.Leha ho le joalo, ha e sebelisoa ho thepa ea 'nete ea ho paka lijo, ho hlokahala liphetoho tse ling ho ikamahanya le litšobotsi tsa lijo ka botsona, e le ho fihlela phello e ntle ea ho paka.
PLA e ka theha tikoloho e fokolang ea asiti holim'a sehlahisoa, se nang le motheo oa antibacterial le antifungal.Haeba li-antibacterial agents tse ling li sebelisoa ho phaella moo, tekanyo ea antibacterial e fetang 90% e ka finyelloa, e ka sebelisetsoang ho paka lihlahisoa tsa antibacterial.
Ha ho bapisoa le filimi ea LDPE, filimi ea PLA le filimi ea PLA/REO/TiO2, ho kenella ha metsi ha filimi e entsoeng ka PLA/REO/Ag ho phahame haholo ho feta lifiliming tse ling.Ho phethoa ho tloha ho sena hore e ka thibela ka katleho ho thehoa ha metsi a khutsitseng le ho finyella phello ea ho thibela ho hōla ha likokoana-hloko;ka nako e ts'oanang, e boetse e na le phello e babatsehang ea bacteriostatic.
PET/PLA Environmental sheet extrusion line: JWELL e nts'etsapele mohala oa parallel screw extrusion bakeng sa lakane ea PET / PLA, mohala ona o nang le sistimi ea degassing, 'me ha ho na tlhoko ea ho omisa le yuniti ea kristale.Mohala oa extrusion o na le thepa ea matla a fokolang a matla, mokhoa o bonolo oa tlhahiso le tlhokomelo e bonolo.Sebopeho sa screw se arotsoeng se ka fokotsa tahlehelo ea viscosity ea resin ea PET/PLA, roller ea calender ea symmetrical le e tšesaane e phahamisa phello ea ho pholisa le ho ntlafatsa bokhoni le boleng ba lakane.Multi components dosing feeder e ka laola liperesente tsa thepa e sa tsoakoang, lisebelisoa tse nchafatsoang le batch e kholo ka nepo, lakane e sebelisoa haholo indastering ea liphutheloana tsa thermoforming.
