Halogeni ni nini?

Halogeni (Halogen) ni kipengele cha saba A isicho cha chuma, ikiwa ni pamoja na fluorine, klori, bromi, iodi, na astatine. Astatine ni kipengele cha radioactive, ambacho kawaida kinajulikana kama halogen ni fluori, klori, bromu na iodi. Halogen misombo mara nyingi kama retardant moto: PBB, PBDE, TBBP-A, PCB, hexabromidexane, tribromophenol, mfupi mfululizo chloride paraffin, nk, kutumika katika vipengele vya umeme na vifaa, nyumba bidhaa, plastiki, nk. Hali hii ya moto haiwezi kutumika tena, na wakati wa kuchoma na joto inatoa vitu vingi ambavyo vinatishia afya ya binadamu, mazingira na vizazi vifuatavyo.

1. Halogen ni nini?

Kwa mujibu wa taarifa zake, 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.

Matumizi ya Halogen

retardant moto, baridi, solvent, kemikali ya kikaboni, dawa za wadudu, bleacher, defroster ya sufu.

2. Matumizi ya Halogen

Kwa mujibu wa taarifa zake, 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.

Hatari ya Halogens

Sumu kwa mfumo wa kinga, athari kwa mfumo wa endocrine, athari kwa uzazi na maendeleo, athari za kansa, sumu nyingine (magonjwa ya akili na akili), halidi nyingi ni homoni za mazingira.

Kuongeza halogen (fluori, klori, bromu, iodi) katika bidhaa za polymer kama plastiki ili kuboresha hatua ya moto, faida yake ni: hatua ya moto ni ya juu kuliko vifaa vya kawaida vya polymer, hatua ya moto ni karibu 300 ℃. Wakati wa kuchoma, gesi halide (fluori, klori, bromu, iodi) hutolewa, na oksijeni inachukua kwa haraka, hivyo kuzima moto. Lakini hasara zake ni kutolewa kwa kiwango cha juu cha gesi ya klori, inayosababishwa na kupungua kwa kuonekana husababisha kuwa na uhakika wa kutambua njia ya kukimbia, wakati huo huo gesi ya klori ina sumu nguvu sana, inaathiri mfumo wa kupumua wa binadamu, Aidha, kuchoma haligeni polymer iliyotolewa na gesi ya haligeni wakati wa kuchanganya na mvuke wa maji, itazalisha gesi hatari ya kutu (haligeni ya hidrojeni), kusababisha kutu kwa vifaa vingine na majengo.

3. Udhara wa Halogen

Kwa mujibu wa taarifa zake, 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.
