EVA / PEVA Cast Film Extrusion Line
*SEKELETSO
Mohala o etselitsoe hantle ho hlahisa lifilimi tsa EVA le PEVA bakeng sa lits'ebetso tse fapaneng.Moralo o ntlafalitsoeng ka ho fetesisa oa extruder le T die o netefatsa ts'ebetso e phahameng ea ts'ebetso le maemo a fapaneng a likarolo le li-automation li teng ho fihlela litlhoko tsa hau hantle.Mohala o sebelisa resin ea EVA (ho kenyeletsoa 30-33% VA) e le lisebelisoa tse tala ho hlahisa filimi ea EVA ea betri ea letsatsi.E boetse e amohela motsoako oa lisebelisoa tse fapaneng tsa resin joalo ka EVA, LDPE, LLDPE, le HDPE ho kopanya thepa ea bona e ikhethang.Mochini oa rona oa lifilimi oa cast bakeng sa filimi ea EVA / PEVA e etselitsoe ka ho khetheha polymer ea thermoplastic.Ho sebetsa ha filimi ea EVA le filimi ea PEVA ho na le litlhoko tse fapaneng haholo ho li-screw, li-flow channel le li-roller tse tataisang.Lintlha tsohle tsa mochini oa rona oa lifilimi li nka litlhoko tseo kaofela ho nahanela boleng bo holimo.
Ethylene vinyl acetate kapa EVA ke copolymer ea ethylene le vinyl acetate.Ke thermoplastic e otlolohileng haholo le e thata ea ho hlaka le ho benya ha monko o fokolang.EVA e na le khanyetso e ntle ea flex crack le puncture, e batla e sa tsitsa, e khomarela hantle ho li-substrates tse ngata 'me e khona ho koala mocheso e leng se etsang hore tšebeliso ea eona e khahlehe haholo lits'ebetsong tsa lifilimi.
*KOPO
Filimi ea EVA e ka sebelisoa e le encapsulation ea betri ea letsatsi, kapa filimi e khomarelang bakeng sa ho lamination ea khalase.
Lihlahisoa tsa filimi tsa PEVA li na le lits'ebetso tse fapaneng bakeng sa likharetene tsa shaoara, liatlana, lesela la sekhele, lesela la tafole, seaparo sa pula, jj.
Resin ena ea thermoplastic e kopantsoe le li-resin tse ling tse kang LDPE le LLDPE kapa ke karolo ea filimi ea multilayer.Likopanong le li-copolymers, peresente ea EVA e tloha ho 2% ho isa ho 25%.E matlafatsa ho hlaka le ho tiiseha ha olefin (LDPE/LLDPE) athe peresente e phahameng ea EVA e sebelisoa hangata ho fokotsa ntlha ea ho qhibiliha.E boetse e ntlafatsa ts'ebetso ea mocheso o tlase.Ka kakaretso, thepa ea mechine e tla itšetleha ka litaba tsa vinyl acetate;ha karolo ea eona e phahame, e ka tlaase ke mokoallo oa khase le mongobo le ho hlaka ho molemo.
EVA ke tšitiso feela ea karolelano ea likhase le mongobo, e etsang hore e se khetho e ntle bakeng sa lits'ebetso tsa ho paka lijo, ka hona, e nkeloe sebaka ke metallocene PE ho tse ngata tsa lits'ebetso tsena.mPE e boetse e fana ka tack e chesang ka potlako, 'me e na le thepa e ntle ea ho theola, e lumellang lifilimi tse fokolang le ho paka.Leha ho le joalo, EVA e ntse e le thepa ea bohlokoa ea ho paka 'me tlhoko e tla lula e le matla haholo bakeng sa lits'ebetso tseo e seng tsa lijo.
