Kugwiritsa ntchito

1. Selenium dioxide cas 7446-08-4 yomwe imagwiritsidwa ntchito popanga selenium yoyera kwambiri ndi mankhwala ena a selenium, komanso okosijeni komanso chothandizira chamankhwala opangidwa ndi organic.
2. Selenium dioxide cas 7446-08-4 yomwe imagwiritsidwa ntchito ngati organic pawiri oxidant, chothandizira, mankhwala reagent, zopangira kupanga mitundu yosiyanasiyana ya selenium.

Malipiro

* Titha kupereka njira zosiyanasiyana zolipirira makasitomala.

* Ndalamazo zikachepa, makasitomala nthawi zambiri amalipira kudzera pa PayPal, Western Union, Alibaba, ndi zina.

* Ndalamazo zikachuluka, makasitomala nthawi zambiri amalipira kudzera pa T/T, L/C akuwona, Alibaba, ndi zina.

Zosungirako

Sungani mu nyumba yosungiramo mpweya wabwino komanso youma.Samalani ndi chinyezi, ndipo zoyikapo ziyenera kusindikizidwa.Kupewa kuwonongeka kwa phukusi.

Kukhazikika

1. White kuwala acicular crystalline ufa, wowawasa kukoma ndi moto kutengeka.Nthunzi wake ndi wachikasu-wobiriwira, ndi kukoma kokoma, wosasunthika pakuwala ndi kutentha, ndi hygroscopic.Imakoma wowawasa ndipo imakhala ndi kutentha.Ndi oxidizing, ndipo selenium monomer adzakhala mpweya akakumana organic kuchepetsa wothandizila.chakupha.

2. Mosavuta kuchepetsedwa kukhala selenium.

3. Gwiritsani ntchito zida zodzitetezera panthawi yogwira ntchito.Samalani nthawi zambiri kuti muwone kuchuluka kwa selenium mumlengalenga.Yang'anani thupi lanu nthawi zonse.Perekani zakudya zokhala ndi mapuloteni ndi amino acid.

4. Kukhazikika kwa mpweya ndi chinyezi.Popeza ndi poizoni kwambiri, tikulimbikitsidwa kuti tigwire ndikugwiritsa ntchito mosamala mu fume hood.
