Dimethyl disulfide ili ndi fungo la anyezi loopsa kwambiri. Silimayambitsa kununkhira. Chodabwitsa n'chakuti, ngakhale ambiri amaona kuti fungo lake ndi loipa kwambiri ngati latchulidwa pamwambapa, likachepetsedwa, fungo lake limaonedwanso kuti ndi lokoma. Dimethyl disulfide nthawi zambiri imagwiritsidwa ntchito limodzi ndi zinthu zina zokometsera muzakudya, kuphatikizapo zakudya zophikidwa, tchizi, mkaka wozizira, nyama, supu, zokometsera zokometsera, kukoma kwa zipatso, maswiti ofewa, gelatin, ma pudding, ndi zakumwa zoledzeretsa komanso zopanda mowa.

Kagwiritsidwe Ntchito
Mu mafakitale, Dimethyl disulfide imagwiritsidwanso ntchito ngati chothandizira sulfiding kuti chithandizire kusintha kwa zinthu m'mafakitale oyenga mafuta ndi mafakitale ena. Ili ndi mphamvu yotsika ya 16 ℃ (61 °F) yomwe imabweretsa zoopsa pamoto panthawi yogwiritsa ntchito mafakitale oyenga mafuta. Chifukwa cha fungo lake lamphamvu komanso mphamvu yotsika ya flash, Dimethyl disulfide nthawi zambiri imafuna kusungidwa pansi pa kupanikizika kwa nayitrogeni m'zidebe zotsekedwa.
Dimethyl disulfide ili ndi fungo la sulfure lofanana ndi la adyo ndi nsomba zomwe zikuwola. Chifukwa cha fungo losiyana la mankhwala a sulfure, ofanana ndi DMDS, nthawi zambiri amawonjezeredwa ku mpweya wachilengedwe ndi propane kuti achenjeze anthu za kutuluka kwa madzi ndikuteteza anthu. Chifukwa chake, fungo la DMDS fumigation likhoza kusokonezedwa ndi kutuluka kwa mpweya. DMDS ili ndi fungo locheperako la pafupifupi 7 ppb, lomwe ndi locheperako nthawi 8 kuposa mulingo wozikidwa pa thanzi womwe EPA imaganiza kuti ndi wotetezeka (55 ppb).
Dimethyl disulfide imagwiritsidwa ntchito ngati chowonjezera chapakati komanso chowonjezera chakudya mu anyezi, adyo, tchizi, nyama, supu, zokometsera zokoma ndi zipatso. Imagwiritsidwa ntchito m'malo oyeretsera mafuta ngati chowonjezera cha sulfide. Imagwiritsidwa ntchito m'malo mwa alfa m'malo mwa 2-methylfuran-acrolein popanga chakudya. Imagwira ntchito popanga 4-(methylthio)phenol. Kuphatikiza apo, imagwiritsidwa ntchito m'malo mwa methyl mercaptan ngati chowonjezera cha mafuta a jet. Imagwiritsidwa ntchito mu zokometsera zopangira komanso choletsa dzimbiri. Kuphatikiza apo, imagwiritsidwa ntchito ngati chofukizira champhamvu cha nthaka muulimi.
Kulongedza
200KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
