Biodegradable Injection Molding Zinthu Zosinthidwa
Angapo mafakitale njira angakwanitse ntchito (ie mkulu maselo kulemera) PLA.Ma monomer awiri akuluakulu amagwiritsidwa ntchito: lactic acid, ndi cyclic di-ester, lactide.Ambiri njira PLA ndi mphete-kutsegula polymerization lactide zosiyanasiyana zitsulo zothandizira (nthawi zambiri malata octoate) mu njira kapena monga kuyimitsidwa.The zitsulo-catalyzed anachita kumayambitsa racemization wa PLA, kuchepetsa stereoregularity poyerekeza ndi zinthu poyambira (nthawi zambiri chimanga wowuma).
PLA imasungunuka m'magulu osiyanasiyana a organic solvents.Ethyl acetate, chifukwa cha kupezeka kwake kosavuta komanso chiopsezo chochepa chogwiritsa ntchito, ndichofunika kwambiri.PLA 3D chosindikizira ulusi amasungunuka pamene ankawaviika ethyl acetate, kupanga izo zosungunulira zothandiza kuyeretsa 3D yosindikiza mitu extruder kapena kuchotsa PLA zothandizira.Malo otentha a ethyl acetate ndi otsika mokwanira kuti azitha kusalalanso PLA m'chipinda cha nthunzi, mofanana ndi kugwiritsa ntchito mpweya wa acetone kuti ukhale wosalala ABS.
Zosungunulira zina zotetezeka zomwe zimagwiritsidwa ntchito ndi propylene carbonate, zomwe ndi zotetezeka kuposa ethyl acetate koma zimakhala zovuta kugula malonda.Pyridine ingagwiritsidwenso ntchito komabe izi ndizotetezeka kwambiri kuposa ethyl acetate ndi propylene carbonate.Ilinso ndi fungo loyipa la nsomba.
SPLA jekeseni akamaumba Features
Zigawo zikuluzikulu za mankhwala ndiPLA, PBAT ndi inorganic Mtundu uwu wa mankhwala ali ndi meltfluidity wabwino ndi mkulu mawotchi mphamvu, ndipo makamaka oyenera jakisonimolding.Itha kupanga zinthu zamabowo ambiri ndi nthawi yochepa yozizirira, yotsika mtengo, komanso kuwonongeka mwachangu.The mankhwala ali processing wabwino ndi physicalproperties, ndipo angagwiritsidwe ntchito mwachindunji akamaumba jekeseni kupanga zosiyanasiyanamolded mankhwala.
SPLA Injection Molding Application Field
High kulimba, mkulu mphamvu 3D kusindikiza zinthu kusinthidwa,
Zotsika mtengo, zamphamvu kwambiri zosindikizira za 3D zosinthidwa
Makalasi Owumba Jakisoni wa SPLA Ndi Kufotokozera
| Gulu | Kufotokozera | Malangizo Okonzekera |
| Chithunzi cha SPLA-IM115 | Zigawo zikuluzikulu za mankhwala ndiPLA, PBAT ndi inorganic Mtundu uwu wa mankhwala ali ndi meltfluidity wabwino ndi mkulu mawotchi mphamvu, ndipo makamaka oyenera jakisonimolding. | Mukamagwiritsa ntchito mankhwalawa pomanga jekeseni, tikulimbikitsidwa kuti kutentha kwa jekeseni kukhale 180-195 |
