Kodi carbon fiber ndi chiyani?

PLA ndi imodzi mwazinthu zowonongeka zapulasitiki. Polylactic acid ndi polima wopangidwa kuchokera ku lactic acid monga zopangira zazikulu. Pakalipano, ndi pulasitiki yokhwima kwambiri, yaikulu kwambiri komanso yogwiritsidwa ntchito kwambiri padziko lonse lapansi.

Pali njira ziwiri zopangira PLA, zomwe ndi lactide mphete-lotseguka polymerization ndi polycondensation yolunjika, yomwe polymerization ya lactide yotseguka imagwiritsidwa ntchito kwambiri. Mu lactide mphete-kutsegula polymerization, kaphatikizidwe ndi kuyeretsa wapakatikati lactide ndi pachimake teknoloji ndi zovuta pochita. Zomwe zimachitikira zimakhala zovuta, ndondomekoyi ndi yovuta, zofunikira zaumisiri ndizokwera, ndipo mtengo wopangira ndi wokwera.
