Isicelo

1. I-Selenium dioxide cas 7446-08-4 esetshenziswa ekukhiqizeni i-selenium ehlanzekile kakhulu nezinye izinhlanganisela ze-selenium, kanye ne-oxidant kanye ne-catalyst yezidakamizwa zokwenziwa eziphilayo.
2. I-Selenium dioxide cas 7446-08-4 esetshenziswa njenge-organic compound oxidant, i-catalyst, i-chemical reagent, impahla eluhlaza ekukhiqizeni izingxube ezihlukahlukene ze-selenium ezingaphili.

Inkokhelo

* Singahlinzeka ngezindlela zokukhokha ezihlukahlukene ngokukhetha kwamakhasimende.

* Uma inani lilincane, amakhasimende ngokuvamile akhokha nge-PayPal, i-Western union, i-Alibaba, njll.

* Uma inani likhulu, amakhasimende ngokuvamile akhokha nge-T/T, L/C lapho ebona, i-Alibaba, njll.

* Ngaphandle kwalokho, amakhasimende amaningi ngokwengeziwe azosebenzisa i-Alipay noma i-WeChat akhokhe ukuze enze inkokhelo.

Izimo zokugcina

Gcina endaweni engenisa umoya futhi eyomile.Naka umswakama, futhi ukupakishwa kufanele kuvalwe.Ukuvimbela umonakalo emaphaketheni.

Ukuzinza

1. Ukukhanya okumhlophe kwe-acicular crystalline powder, ukunambitheka okumuncu nomuzwa ovuthayo.Umhwamuko wawo uphuzi ngokuluhlaza okotshani, unokunambitheka okubabayo, uzinzile ekukhanyeni nasekushiseni, futhi une-hygroscopic.Izwakala imuncu futhi inomuzwa wokuvutha.I-oxidizing, futhi i-monomer selenium izoba nemvula lapho ihlangana ne-organic rencing agent.enoshevu.

2. Yehliswa kalula ibe selenium.

3. Sebenzisa izinto zokuzivikela ngesikhathi sokusebenza.Naka ukuhlola njalo ukugcwala kwe-selenium emoyeni.Hlola umzimba wakho njalo.Nikeza ukudla okucebile ngamaprotheni nama-amino acid.

4. Izinzile emoyeni nasemoyeni.Njengoba inobuthi obukhulu, kuyanconywa ukuthi uyiphathe futhi uyisebenzise ngokucophelela ku-fume hood.
