Nhau - TPU Base Film Processing Technology

Chii chinonzi TPU Base Firimu?

TPU firimu ifirimu rakagadzirwa kubva kuTPU granules kuburikidza nemaitiro akakosha senge calendering, kukanda, kuridza firimu, uye kukoira. Nekuti TPU firimu rine hunhu hwepamusoro mwando permeability, kupindira kwemhepo, kutonhora, kuramba kupisa, kusapfeka, kudhonzerana kukuru, simba rekudhonza, uye kutsigirwa kwemutoro mukuru, kushanda kwayo kwakakura kwazvo, uye firimu reTPU rinogona kuwanikwa mune zvese. zvehupenyu hwezuva nezuva. Semuenzaniso, mafirimu eTPU anoshandiswa mukutakura zvinhu, matende epurasitiki, mabhodhoro emvura, machira akaumbwa nemitoro, nezvimwewo. Parizvino, mafirimu eTPU anonyanya kushandiswa mumafirimu ekudzivirira pendi mumunda wemotokari.

Kubva pachimiro chekutarisa, TPU pendi yekudzivirira firimu inonyanya kuumbwa neanoshanda coating, TPU base firimu uye adhesive layer. Pakati pavo, iyo TPU base firimu ndiyo yakakosha chikamu chePPF, uye hunhu hwayo hwakakosha, uye mashandiro ayo akanyanya kukwirira.

Iwe unoziva maitiro ekugadzira eTPU?

Dehumidification uye kuomesa: molecular sieve dehumidification desiccant, kupfuura 4h, unyoro <0.01%

Maitiro tembiricha: tarisa kune yakasvibirira vagadziri vanokurudzirwa, zvinoenderana nekuoma, MFI marongero

Filtration: tevera kutenderera kwekushandisa, kudzivirira mavara matema ekunze

Melt pombi: extrusion vhoriyamu kudzikamisa, yakavharwa-loop kutonga neiyo extruder

Screw: Sarudza yakaderera shear chimiro cheTPU.

Kufa musoro: gadzira nzira yekuyerera zvinoenderana neiyo rheology yealiphatic TPU zvinhu.

Nhanho imwe neimwe yakakosha pakugadzirwa kwePPF.

Iyi nhamba inotsanangura muchidimbu maitiro ese ekugadzirisa aliphatic thermoplastic polyurethane kubva granular masterbatch kuenda kune firimu. Inosanganisira kusanganiswa kwemaitiro ezvinyorwa uye dehumidification uye kuomesa system, iyo inopisa, shears uye plasticizes zvimedu zvakasimba mukunyunguduka (kunyunguduka). Mushure mekusefa uye kuyera, iyo otomatiki inofa inoshandiswa kuumba, kutonhorera, kukwana iyo PET, uye kuyera ukobvu.

Kazhinji, x-ray ukobvu kuyerwa kunoshandiswa, uye yakavanzika yekudzora sisitimu ine mhinduro isina kunaka kubva kune otomatiki kufa musoro inoshandiswa. Pakupedzisira, kucheka kwemucheto kunoitwa. Mushure mekuongorora kukanganisa, vatarisi vemhando vanoongorora firimu kubva kumakona akasiyana kuti vaone kana zvimiro zvemuviri zvinosangana nezvinodiwa. Pakupedzisira, mipumburu inopetwa uye inopiwa kune vatengi, uye pane maturation process pakati.

Processing tekinoroji mapoinzi

TPU masterbatch: TPU masterbatch mushure mekupisa kwakanyanya

kukanda muchina;

TPU firimu;

Coating machine gluing: TPU yakaiswa pane thermosetting / light-setting coating machine uye yakaputirwa nemucheka we acrylic glue / light-curing glue;

Laminating: Laminating iyo PET yekuburitsa firimu ine glued TPU;

Coating (inoshanda layer): nano-hydrophobic coating paTPU mushure mekucheka;

Kuomesa: kuomesa glue pane firimu nekuomeswa kunouya nemuchina wekuputira; nzira iyi ichagadzira shoma shoma organic tsvina gasi;

Kutsemura: Zvinoenderana nezvinodiwa zvekurongeka, iyo firimu inosanganiswa ichatsemurwa muhukuru hwakasiyana nemuchina wekutsemura; nzira iyi ichabudisa mipendero nemakona;

Rolling: firimu rinoshandura ruvara mushure mokunge kuputika kwakuvadzwa kuita zvigadzirwa;

Yakapedzwa chigadzirwa kurongedza: kurongedza chigadzirwa mudura.
