PLA / PET Yonyamula Pazinthu Mapepala Ochotsa Mzere

Polylactic acid (PLA) ndi mtundu wina watsopano wazinthu zosinthika zomwe zingapangidwenso zowononga chilengedwe. PLA imapangidwa kuchokera kuzinthu zopangira wowuma zomwe zimapangidwanso ndi mbewu zowonjezeredwa (monga chimanga, chinangwa, ndi zina). Glucose idapezedwa kuchokera ku wowuma ndi saccharification, ndiye kuti kuyera kwambiri kwa lactic acid kumapangidwa ndi kutenthetsa shuga ndi mitundu ina, kenako polylactic acid wokhala ndi ma molekyulu ena amapangidwa ndi kaphatikizidwe ka mankhwala. Ili ndi kuwonongeka kwa chilengedwe, imatha kuwonongeka kwathunthu ndi tizilombo tachilengedwe m'zinthu zina zitatha kugwiritsidwa ntchito, ndipo pamapeto pake imatulutsa mpweya woipa ndi madzi, womwe suwononga chilengedwe. Izi ndizothandiza kwambiri poteteza chilengedwe, ndipo chimadziwika kuti ndichinthu chachilengedwe.

Thiabendazole angagwiritsidwe ntchito yopanga mapepala PET ndi PLA, kuchepetsa mowa mphamvu ya chisanadze crystallization kuyanika, ndipo azolowere yopanga zipangizo sekondale. Ili ndi mawonekedwe azokolola zambiri, kugwiritsa ntchito mphamvu zochepa komanso kupangira pulasitiki kwabwino. Chowotcheracho ndichinthu chomanga nyumba chophatikiza zingapo, ndipo chimakhala ndi mitundu ingapo ya ntchito. Sikokwanira kupanga PET, komanso kuyenera ku PLA zida zowola ndi zinthu zowononga wowuma.

PLA / PET yoteteza zachilengedwe ma CD amtundu wa extrusion amapanga makamaka opangidwa ndi ma extruder awiri, ma changer, ma metering pump, die, odzigudubuza atatu, ozizira bulaketi, samatha, akumulowetsa ndi zina zambiri. Mtundu watsopano wa extruder wokhala mbali ziwiri umakhala ndi mawonekedwe a mphamvu zochepa, njira yosavuta komanso kukonza zida. Kuphatikizika kwake kophatikizika kumachepetsa kutsika kwamatope a utomoni wa PET. Makina oyenda ndi mipanda yolumikizana bwino amathandizira kuti kuziziritsa kuzikhala bwino komanso zokolola komanso mtundu wa mapepala. Chipangizo chopangira zida zingapo chimatha kuwongolera kuchuluka kwa zida zatsopano, zobwezeretsanso, masterbatch ndi zina zotero. Mapepala omwe amapangidwa amatha kugwiritsidwa ntchito pantchito yosindikiza ndi kuyika pulasitiki. Dongosolo lamagetsi limagwiritsa ntchito masisitimu a Nokia, omwe amadziwika ndi magwiridwe antchito, makina apamwamba komanso kupulumutsa ndalama.

Mbiyayo ili ndi zotulutsa zingapo ziwiri kuti zitsimikizire kutulutsa madzi ndi gasi.

The extruder ili ndi phulusa losungunuka metering lomwe limatulutsa magetsi pafupipafupi komanso chotseka chokha chothamangitsa kuthamanga ndi kuthamanga.

Makina onse amatenga PLC kuwongolera kuti azindikire kuwongolera kolowera kwa parameter, magwiridwe antchito, mayankho ndi ntchito za alamu.

Latsopano osayanika PET atatu-utsi extrusion kupanga mzere (palibe chifukwa crystallization dehumidification kuyanika dongosolo) ndi wapamwamba kwambiri PET ndi PLA pepala unit loyambitsidwa ndi kampani. Njira zake zopangira ndizosavuta, kugwiritsa ntchito mphamvu zamagetsi ndizotsika, ndipo mtengo wopangira umachepa kwambiri.

Gwiritsani ntchito: Kukonzekera bwino, kuwonekera poyera, zotchinga, zopanda poizoni, zopanda fungo, zopanda kuipitsa, zosavuta kuzikonzanso ndi zina.

Zingalowe zopanga: kulongedza chakudya, mabokosi azoseweretsa, mabokosi olembera, mabokosi amphatso, zida zamanja ndi ma CD.

Ntchito Yotchinga: Zida Zamagetsi Zamagetsi.

Kugwiritsa ntchito kwakukulu: kupinda, kolala yovala, zokongoletsera, zikwatu, zikuto.

Ntchito yapadera: zida zamankhwala, mapangidwe azachipatala, chitetezo chazitsulo chotsutsana ndi dzimbiri, mayikirowevu opangira mayikirowevu.
