Uma uthenga ikesi le-smartphone, izinto ozikhethayo ngokuvamile ziyi-silicone, i-polycarbonate, ipulasitiki eqinile, ne-thermoplastic polyurethane (TPU).Uma uzibuza ukuthi iyini i-TPU, sizoyidiliza (ngokubuka).
Iyini i-thermoplastic?
Njengoba cishe uyazi, ipulasitiki iyimpahla yokwenziwa (imvamisa) eyenziwe ngama-polymers okwenziwa.I-polymer into eyakhiwe ngama-monomers.Ama-molecule e-Monomer akha amaketanga amade nomakhelwane bawo, akhe ama-macromolecule amakhulu.
I-Plasticity yindawo enikeza ipulasitiki igama layo.Ipulasitiki isho nje ukuthi impahla eqinile ingakhubazeka unomphela.Ipulasitiki ingabunjwa kabusha ngokubumba, ukukhama noma ukufaka ingcindezi.
I-Thermoplastics ithola igama layo kusukela ekuphenduleni kwayo ekushiseni.I-Thermoplastics iba ipulasitiki emazingeni okushisa athile, okungukuthi, lapho ibunjwa ngendlela efunwa ngayo.Njengoba ephola, isimo sawo esisha siba unomphela aze afudumale futhi.
Izinga lokushisa elidingekayo ukwenza i-thermoplastic flexible liphezulu kakhulu kunalokho ongakwazi ukumelana nefoni yakho.Ngakho-ke, imikhiqizo ye-thermoplastic ayigugi neze ngesikhathi sokusetshenziswa okujwayelekile.
Amaphrinta we-Fused Deposition Modeling 3D angamaphrinta e-3D avame kakhulu emakethe namuhla futhi asebenzisa ama-thermoplastics.Izinhlayiya zepulasitiki ziphakelwa nge-extruder, futhi iphrinta yendlalela umkhiqizo wayo, opholisa futhi uqine ngokushesha.
Kuthiwani nge-polyurethane?
I-Polyurethane (PU) ibhekisela ekilasini lama-polymer ephilayo axhunywe ngamabhondi e-polyurethane."I-Organic" kulo mongo ibhekisela kumakhemikhali ezinto eziphilayo agxile kumakhemikhali ekhabhoni.Ikhabhoni iyisisekelo sempilo njengoba siyazi, yingakho igama.
Enye yezinto eyenza i-polyurethane ikhetheke ukuthi ayiyona inhlanganisela ethile.Ama-polyurethanes angenziwa ngama-monomers amaningi ahlukene.Yingakho kuyisigaba sama-polymers.
