Ngati mukugula foni yam'manja, zosankha zanu nthawi zambiri zimakhala silikoni, polycarbonate, pulasitiki yolimba, ndi thermoplastic polyurethane (TPU).Ngati mukudabwa kuti TPU ndi chiyani, tiyiphwanya (zowoneka).
Kodi thermoplastic ndi chiyani?
Monga mukudziwira, pulasitiki ndi zinthu zopangidwa (nthawi zambiri) zopangidwa kuchokera ku ma polima opangira.Polima ndi chinthu chopangidwa ndi ma monomers.Mamolekyu a monomer amapanga maunyolo aatali ndi anansi awo, kupanga ma macromolecules akulu.
Plasticity ndi chinthu chomwe chimapatsa pulasitiki dzina lake.Pulasitiki imangotanthauza kuti zinthu zolimba zimatha kupunduka kotheratu.Pulasitiki imatha kupangidwanso ndi kuumba, kufinya kapena kukakamiza.
Thermoplastics amapeza dzina lawo kuchokera ku mayankho awo pakutentha.Thermoplastics amakhala pulasitiki pa kutentha kwina, ndiye kuti, akapangidwa momwe amafunira.Akazizira, mawonekedwe awo atsopano amakhala osatha mpaka atatenthedwanso.
Kutentha kofunikira kuti thermoplastic flexible ndi yokwera kwambiri kuposa momwe foni yanu ingapirire.Chifukwa chake, zinthu za thermoplastic sizimapunduka pakagwiritsidwe ntchito bwino.
Osindikiza a Fused Deposition Modeling 3D ndiye osindikiza ambiri a 3D pamsika masiku ano ndipo amagwiritsa ntchito thermoplastics.Filaments pulasitiki amadyetsedwa kudzera extruder, ndi chosindikizira zigawo zigawo zake, amene kuziziritsa ndi kulimba mofulumira.
Nanga bwanji polyurethane?
Polyurethane (PU) amatanthauza gulu la ma polima achilengedwe olumikizidwa ndi ma polyurethane bond."Organic" m'nkhaniyi akunena za organic chemistry yokhazikika pamagulu a carbon.Mpweya ndiye maziko a moyo monga tikudziwira, motero dzina.
Chimodzi mwazinthu zomwe zimapangitsa polyurethane kukhala yapadera ndikuti sizinthu zenizeni.Ma polyurethanes amatha kupangidwa kuchokera ku ma monomers osiyanasiyana.Ndicho chifukwa chake ndi gulu la ma polima.
