Kudziwa PLA zinthu zipangizo 3D kusindikizidwa

makasitomala ambiri ndi abwenzi amandifunsa ngati PLA ndi pulasitiki? Pano pali nkhani akhakula chimene chili PLA lero.

PLA ndi English chidule asidi polylactic, chimene chidalembedwa monga: polylacticacid. asidi Polylactic (PLA) ndi buku biobased ndi chuma biodegradable zopangwidwa kuchokera ku zipangizo wowuma yaiwisi akufuna ndi chuma zongowonjezwdwa mbewu monga chimanga. Wowuma zopangira analandira mwa saccharification kupeza shuga, kenako shuga ndi mavuto ena thovu kubala mkulu-chiyero asidi lactic, ndiyeno ena maselo kulemera asidi polylactic ndi apanga ndi kaphatikizidwe mankhwala. Iwo ali biodegradability wabwino. Pambuyo ntchito, tingathe kwathunthu adzitsitsa ndi tizilombo mu chikhalidwe akamaziwononga, ndipo potsiriza umabala mpweya woipa komanso madzi, zomwe si amaipitsa malo. Zimenezi n'zothandiza kwambiri kwa chilengedwe ndi chimatengedwa ngati chuma wochezeka.

lipoti anafika ponena kuti zotsatira za kutsogolera, Mercury, cadmium, chromium, biphenyl, ndi diphenyl efa anali wogwirizana ndi zaka 11 EU malangizo pa kagwiritsidwe ntchito ka zinthu yoletsedwa, ndipo zotsatira za chitsanzo 001 sanali wapezeka. Na- si dected.

Kafukufuku zonse tatchulazi, zikusonyeza kuti PLA ndi zinthu zabwino, koma ngozi chakudya alidi nkhani ya nkhawa kwambiri kwa aliyense, kapena kukhala osamala.

Mundirole ine ndiyankhule za zofooka zina ndi ngozi zina zobisika za PLA. Choyamba, PLA si kugonjetsedwa ndi kutentha, ndipo kwenikweni akuyamba deform mozungulira 60 °. Ngati nkhungu chakudya, izo ziyenera kukhala ozizira amachiritsidwa; PLA zinthu zikhoza adzitsitsa, umene uli mwayi ndipo sangathe. Ngakhale wochezeka, pamafunika 3D yosindikiza zinthu mankhwala kalasi. Chokhalitsa ndi lalifupi gulu; mu ndondomeko yosindikiza, chifukwa ndi mkulu-kutentha kusungunuka, izo adzateteza particles, ngakhale particles okha si a poizoni, koma izi pang'ono ngati PM2.5, yaitali kupuma kapena kuwonongeka kwa mapapo anthu, Choncho, 3D yosindikiza chinapangidwira makamaka mpweya wokwanira.

Choncho, PLA ndi chuma wochezeka kuti aliyense akhoza kugwiritsa ntchito ndi chidaliro.

Aulesi dumpling bokosilo

 Pomaliza kufuula mawu, luso chimasintha moyo, 3D kusindikiza kwa maloto ndi chenicheni!
