Iimeko zokugcina

Gcina kwindawo yokugcina umoya kunye neyomileyo. Nika ingqalelo kumswakama, kwaye ukupakishwa kufuneka kutywinwe. Ukuthintela umonakalo kwipakethe.

Uzinzo

1. Ukukhanya okumhlophe kwe-acicular crystalline powder, incasa emuncu kunye nemvakalelo evuthayo. Umphunga wayo utyheli-luhlaza, unencasa erhabaxa, uzinzile ekukhanyeni nakubushushu, kunye ne-hygroscopic. Inencasa imuncu kwaye inomvandedwa otshisayo. I-oxidizing, kwaye i-selenium ye-monomer iya kuba nemvula xa idibana ne-agent yokunciphisa i-organic. enetyhefu.

2. Ukunciphisa ngokulula kwi-selenium.

3. Sebenzisa izixhobo zokukhusela ngexesha lokusebenza. Nika ingqalelo rhoqo ukujonga ukuxinana kwe-selenium emoyeni. Hlola umzimba wakho rhoqo. Ukubonelela ngokutya okutyebileyo kwiiprotheyini kunye ne-amino acids.

4. Izinzile emoyeni kunye nokufuma. Njengoko inetyhefu kakhulu, kuyacetyiswa ukuba iphathwe kwaye isetyenziswe ngononophelo kwi-fume hood.
