Kusukela maphakathi noJulayi, kusekelwa uchungechunge lwezinto ezinhle njengokwabiwa kwamandla kwesifunda kanye nokugcinwa kwemishini, imakethe ye-calcium carbide yasekhaya ibilokhu ikhuphuka. Kusukela ngoSepthemba, isimo sokuthululwa kwamaloli e-calcium carbide ezindaweni zabathengi eNyakatho China naseCentral China siye senzeka kancane kancane. Amanani okuthenga aqhubeke nokuwohloka kancane futhi amanani ehlile. Esigabeni sokugcina semakethe, ngenxa yokuqaliswa kwamanje kwezitshalo ze-PVC zasekhaya ezingeni eliphakeme, futhi kunezinhlelo ezimbalwa zokulungisa kamuva, i-dema yemakethe ezinzile.
