Tani waxay ka dhigaysaa kuwo ku habboon abuurista agab baakado oo indhaha soo jiidanaya oo ilaalin kara alaabada inta lagu jiro safarka iyo kaydinta iyadoo sidoo kale saameyn weyn ku yeelanaysa macaamiisha.
Warshadaha dhejisyada iyo dahaarka, melamine-keennu waa qayb qiimo leh. Waxaa loo isticmaalaa qaabaynta dhejisyada si loo hagaajiyo xooggooda isku xidhka iyo cimri dhererka. Dahaarka, melamine wuxuu ka caawiyaa kor u qaadista adkaanta iyo iska caabbinta kiimikada ee dusha sare ee dahaarka leh. Hadday tahay isku dhejinta qaybaha alaabta guriga ama ilaalinta dusha sare ee birta ka hortagga daxalka, dhejisyada iyo dahaarka ku salaysan melamine ee laga sameeyay badeecadeenna waxay bixiyaan waxqabad la isku halleyn karo.
