Umqedazwe we-coronavirus ubangele ukwanda okukhulu kwesidingo samashidi e-polymethyl methacrylate (PMMA), asetshenziswa emhlabeni wonke njengezithiyo zokuvikela ukuvimbela ukusabalala kwaleli gciwane.
Lolu uhlelo olusha lokusebenza lwamashidi, namabhuku oku-oda agcwele iningi lango-2020 abakhiqizi bamashidi abalingiswa nakhishiwe.
Abanye babheke nokutshala imali emishinini emisha yokukhipha ama-extrusion, ukuze kwandiswe umkhiqizo, njengoba izitshalo sezisebenza ngo-100%.
Omunye umdayisi uthe izokwazi ukuphinda kabili umkhiqizo wayo ngokuya ngesidingo, kodwa ivinjelwe amaphethini okukhiqiza izitshalo.
Isidingo esiphezulu seshidi elibonisa ngale sisiza ukulungisa okunye ukusetshenziswa okubuthakathaka okuvela ezinsizeni ezinkulu zezimoto nezokwakha.
Ukufunwa okuphezulu okuvela emkhakheni wamashidi kubangele ekwenyukeni kwezintengo ze-PMMA resin, njengoba abanye abadlali becaphuna ukwenyuka ngo-25% ngonyaka odlule.
