Engxenyeni yokuqala ka-2022, imakethe yasekhaya ye-calcium carbide ayizange iqhubeke nokuguquguquka okubanzi ngo-2021. Imakethe iyonke yayiseduze nomugqa wezindleko, futhi yayingaphansi kokuguquguquka nokulungiswa ngenxa yomthelela wezinto ezingavuthiwe, ukuhlinzekwa kanye nesidingo. , kanye nezimo ezansi nomfula. Engxenyeni yokuqala yonyaka, kwakungekho umthamo omusha wokunwetshwa wezitshalo ze-PVC ze-calcium carbide zasekhaya, futhi ukwanda kwesidingo semakethe ye-calcium carbide bekunomkhawulo. Kunzima kumabhizinisi e-chlor-alkali athenga i-calcium carbide ukuze agcine umthwalo ozinzile isikhathi eside.
