EVA / PEVA Cast Film Extrusion Line
* NHUNGAMIDZO
Mutsetse wakanyatsogadzirwa kugadzira EVA nePEVA mafirimu ekushandisa kwakasiyana.Iyo yakanyanya optimized dhizaini ye extruder uye T kufa inovimbisa yakakwirira-kuita extrusion uye akasiyana mazinga ezvimiro uye otomatiki anowanikwa kuti asangane nezvido zvako.Mutsara unoshandisa EVA resin (inosanganisira 30-33% VA) semidziyo yekugadzira EVA solar bhatiri encapsulation firimu.Iyo zvakare inogashira musanganiswa weakasiyana resin zvinhu zvakaita seEVA, LDPE, LLDPE, uye HDPE kusanganisa zvakasarudzika zvivakwa.Yedu yekukanda firimu muchina weEVA / PEVA firimu rakagadzirirwa zvakanyanya kune iwo thermoplastic polymer.Kugadziriswa kweEVA firimu uye PEVA firimu rine zvakasiyana chaizvo zvinodiwa pane screws, kuyerera chiteshi uye inotungamira rollers.Zvese zvemuchina wedu wekukanda firimu zvinotora zvese izvo zvinodiwa mukufunga nezvemhando yepamusoro.
Ethylene vinyl acetate kana EVA icopolymer ye ethylene uye vinyl acetate.Iyo yakanyanyisa elastic uye yakaoma thermoplastic yekujeka kwakanyanya uye kupenya nekunhuhwirira kushoma.EVA ine yakanaka flex crack uye puncture resistance, inert inert, inonamira zvakanaka kune akawanda substrates uye inopisa sealable inoita kuti kushandiswa kwayo mumafirimu kunyanye kukwezva.
*KUITA
EVA firimu rinogona kushandiswa se solar bhatiri encapsulation, kana adhesive firimu regirazi lamination.
Zvigadzirwa zvemufirimu zvePEVA zvine maitiro akasiyana siyana ekugeza keteni, magurovhosi, jira reamburera, jira retafura, jasi remvura nezvimwe.
Iyi thermoplastic resin inobatanidzwa nemamwe marenzi seLDPE neLLDPE kana kuti chikamu chemufirimu we multilayer.Mumisanganiswa uye macopolymers, iyo muzana yeEVA inotangira pa2% kusvika 25%.Inosimudzira kujeka uye kuvharika kweolefins (LDPE/LLDPE) nepo chikamu chepamusoro cheEVA chinowanzo shandiswa kuderedza nzvimbo yekunyungudika.Iyo zvakare inovandudza yakaderera tembiricha kuita.Kazhinji, iyo mechanical properties ichaenderana nevinyl acetate content;iyo yakakwirira chikamu chayo, iyo yakaderera ndiyo inodzivirira gasi uye unyoro uye zviri nani kujeka.
EVA ingori avhareji chipingamupinyi kune magasi uye unyoro, izvo zvinoita kuti ive isiri sarudzo yakanaka yekudya kurongedza maapplication uye, nekudaro, yakatsiviwa nemetallocene PE mune mazhinji eaya maapplication.mPE inopawo kukurumidza kupisa tack, uye ine zvirinani pasi-gauging zvivakwa, izvo zvinobvumira matete mafirimu uye kurongedza.Zvakangodaro, EVA inoramba iri yakakosha kurongedza zvinhu uye kudiwa kucharamba kwakasimba kunyanya kune zvisiri zvechikafu kunyorera.

* ZVINHU & ZVAKANAKA
1) Chero firimu hupamhi (kusvika 4000mm) pane anoraswa nemutengi.
2) Yakanyanya kuderera kusiyanisa kwefirimu ukobvu
3) In-line firimu kumucheto trim uye recycling
4) In-line extrusion coating inosarudzwa
5) Auto film winder ine saizi yakasiyana yemhepo shaft
