1. Menene Halogen?

Yana da kyau a yi amfani da shi. Halogen: Group VIIA in periodic table which is non-metal elements including Fluorine, Chlorine, Bromine, Iodine and Astatine. Since Astatine is a radioactive element, halogens are normally means Fluorine, Chlorine, Bromine and Iodine.

2. Amfani da Halogen

Yana da kyau a yi amfani da shi. Halogen is being used in a wide range of electronic device and its sub-parts including machine case, printed circuit board, cable wire, plastic parts and packaging material. Halogenated materials posses of high heat resistance which limits its combustion in a fire and provides excellent fire safety performance.

3. Kula da Halogen

Yana da kyau a yi amfani da shi. Halogenated plastic materials will release corrosive and toxic gases if ignited in a fire. The corrosive element (i.e. Chlorine) of these gases has the risk to damage electronics function. The toxic element may also affect human immune and endocrine system. Toxicity study has also classified these toxic elements are potentially carcinogenic, heterogenic risk in human.
