Engxenyeni yokuqala ka-2022, imakethe ye-calcium carbide yasekhaya ayizange iqhubeke nomkhuba wokuguquguquka okukhulu ngo-2021. Imakethe iyonke yayiseduze nomugqa wezindleko, futhi yayingaphansi kokushintshashintsha nokulungiswa ngenxa yomthelela wezinto zokusetshenziswa, ukuhlinzekwa kanye nesidingo, kanye nezimo ezingezansi. Engxenyeni yokuqala yonyaka, kwakungekho mandla amasha okukhulisa izitshalo ze-PVC ze-calcium carbide zasekhaya, futhi ukwanda kwesidingo semakethe ye-calcium carbide kwakulinganiselwe. Kunzima ngamabhizinisi e-chlor-alkali athenga i-calcium carbide ukugcina umthwalo ozinzile isikhathi eside.
