Mawu Oyamba

Ndi organic pawiri ndi mankhwala chilinganizo C7H7N3O2.

 

Zina mwazinthu zake ndi izi:

1. Maonekedwe: Ndi woyera mpaka beige crystalline ufa.

2. Malo osungunuka: malo ake osungunuka ndi pafupifupi 166-168 ℃.

3. Kusungunuka: Kumakhala ndi kusungunuka kochepa m'madzi komanso kusungunuka kwakukulu mu ma alcohols ndi ethers.

 

Ntchito zazikulu za calcium ndizo:

1. Chemical Synthesis: itha kugwiritsidwa ntchito ngati chophatikizira chapakatikati mu kaphatikizidwe ka organic, pokonzekera zinthu zina.

2. Kafukufuku wa mankhwala osokoneza bongo: Ili ndi ntchito pa kafukufuku wa mankhwala osokoneza bongo ndipo ingagwiritsidwe ntchito popanga anthu omwe akufuna mankhwala osokoneza bongo.

3. Makampani opanga utoto: Itha kugwiritsidwa ntchito ngati utoto wapakatikati.

 

Njira yokonzekera nthawi zambiri imapangidwa ndi mankhwala, ndipo njira yeniyeni yokonzekera ikhoza kusiyanasiyana malinga ndi cholinga cha ntchito.

 

Ponena za chitetezo, calcium ikhoza kukhala ndi zoopsa zina:

1. Poizoni: Itha kukhala poizoni m'thupi la munthu ndipo imatha kuwononga chilengedwe.

2. Kuyaka: Ikhoza kuyaka ndipo imayenera kusungidwa kutali ndi moto ndi magwero a kutentha.

3. Kuwonekera: Kukhudzana ndi khungu, maso kapena kupuma fumbi kungayambitse mkwiyo ndi kugwirizana.

 

Chifukwa chake, njira zoyenera zotetezera ma labotale, monga kuvala zida zodzitchinjiriza komanso kukhala kutali ndi zoyatsira moto, zimafunikira mukamagwiritsa ntchito ndi kukonza ceramic. Pankhani zenizeni za kagwiritsidwe ntchito ndi kagwiridwe, tikulimbikitsidwa kutchula pepala lachitetezo (SDS) lamankhwala ndi malangizo oyendetsera chitetezo.
