Imakethi ye-melamine ihlale izinzile ngohlengahlengiso oluncinci, kwaye uninzi lweenkampani ziqhuba ii-odolo zangaphambili, nto leyo ebangela uxinzelelo oluphantsi kwimpahla.

Uluhlu lwe-urea yezinto eziluhlaza luyatshintshatshintsha, kwaye kusekho inkxaso ethile yeendleko, kodwa ukunyusa kulinganiselwe.

Ukongeza, ii-odolo ezintsha kwimarike esezantsi zisathe tyaba, kwaye njengoko izinga lomthwalo wokusebenza lihla kancinci kancinci, abavelisi balandela ngengqiqo kwixesha elifutshane, begcwalisa isitokhwe ngesixa esifanelekileyo, kwaye begxila ekulindeni nibone.

Ngexesha elifutshane, imakethi ye-melamine inokuhlala izinzile, kwaye kusafuneka ukuqhubeka nokujonga utshintsho kwimakethi ye-urea.

Ukuba ungathanda ulwazi oluthe kratya, nceda undithumelele i-imeyile.
