Ubhubhani we-coronavirus ubangele ukwanda okukhulu kwemfuno yamaphepha e-polymethyl methacrylate (PMMA), asetyenziswa kwihlabathi liphela njengezithintelo zokukhusela ukusasazeka kwale ntsholongwane.
Esi sisicelo esitsha samaphepha, kunye neencwadi zokuodola zizele kuninzi luka-2020 kubavelisi be-cast kunye namaphepha akhutshiweyo.
Abanye bajonge ukutyalomali koomatshini abatsha bokukhutshwa, ukuze banyuse imveliso, njengoko izityalo sele zisebenza kwi-100%.
Omnye umthengisi uthe uya kukwazi ukuphinda kabini imveliso yayo ngokusekwe kwimfuno, kodwa ithintelwe ziipateni zemveliso yezityalo.
Imfuno ephezulu yephepha elingafihliyo inceda ukukhawulelana nosetyenziso olubuthathaka olusuka kwiimoto eziphambili kunye nezicelo zokwakha.
Imfuno ephezulu evela kwicandelo lamaphepha kukhokelele ekwenyukeni kwamaxabiso e-PMMA resin, abanye abadlali becaphula ukunyuka kwama-25% kulo nyaka uphelileyo.
