He ʻala ʻakaʻakai ikaika ko ka Dimethyl disulfide. ʻAʻole ia he lachrymatory. ʻO ka mea kupanaha, ʻoiai he nui ka poʻe i ʻike i kona ʻala ʻino i nā nui kiʻekiʻe e like me ka mea i ʻōlelo ʻia ma luna, i ka wā i hoʻoheheʻe ʻia ai, ua wehewehe ʻia kona ʻala he ʻoluʻolu. Hoʻohana pinepine ʻia ka Dimethyl disulfide me nā mea ʻono ʻē aʻe i nā huahana meaʻai, me nā mea i hoʻomoʻa ʻia, ka tīhi, nā huahana waiū hau, nā huahana ʻiʻo, nā sopa, nā mea ʻono, nā mea ʻono huaʻai, nā mea ʻono palupalu, gelatin, puddings, a me nā mea inu ʻona a me nā mea inu ʻona ʻole.

Hoʻohana
Ma ke ʻano ʻoihana, hoʻohana ʻia ʻo Dimethyl disulfide ma ke ʻano he mea hoʻoheheʻe sulfiding e hoʻoulu ai i nā hopena i loko o nā hale hoʻomaʻemaʻe aila a me nā ʻoihana ʻē aʻe. He haʻahaʻa kona wahi lapalapa o 16 ℃ (61 °F) e hōʻike ana i nā pōʻino ahi i ka wā e hoʻohana ai i ka hale hoʻomaʻemaʻe. Ma muli o kona ʻala ikaika a me ka wahi lapalapa haʻahaʻa, pono pinepine ʻo Dimethyl disulfide e mālama ma lalo o ke kaomi naikokene i loko o nā pahu pani.
He ʻala sulfurous ko Dimethyl disulfide e like me ke kālika a me nā iʻa palaho. Ma muli o ke ʻala ʻokoʻa o nā hui sulfur, e like me DMDS, hoʻohui pinepine ʻia lākou i ke kinoea kūlohelohe a me ka propane e hoʻomaopopo i nā leaka a pale i nā kānaka. No laila, hiki ke kuhihewa ʻia ke ʻala o ka fumigation DMDS no ka leaka kinoea. ʻO ka paepae ʻala o DMDS ma kahi o 7 ppb, ʻo ia hoʻi ma kahi o 8 mau manawa ka emi ma mua o ka pae olakino i manaʻo ʻia e ka EPA he palekana (55 ppb).
Hoʻohana ʻia ʻo Dimethyl disulfide ma ke ʻano he mea waena a me kahi mea hoʻohui meaʻai i loko o ka ʻakaʻakai, ke kālika, ka tīhi, nā ʻiʻo, nā sopa, nā mea ʻono a me nā mea ʻono hua. Hoʻohana ʻia ia i loko o nā hale hoʻomaʻemaʻe aila ma ke ʻano he mea hoʻoheheʻe sulfiding. Hoʻohana ʻia ia e pani alfa i ka 2-methylfuran-acrolein e hana i nā meaʻai. Pili ia i ka hoʻomākaukau ʻana o 4-(methylthio)phenol. Eia kekahi, hoʻohana ʻia ia e pani i ka methyl mercaptan ma ke ʻano he mea hoʻohui wahie jet. Loaʻa iā ia ka hoʻohana ʻana i loko o ka mea ʻono artificial a me kahi mea pale corrosion. Ma waho aʻe o kēia, lawelawe ia ma ke ʻano he fumigant lepo maikaʻi i ka mahiʻai.
Ka hoʻopili ʻana
200KG/Drum a i ʻole e like me nā koi a ka mea kūʻai aku.
Mālama a me ka mālama ʻana
Ola papa: 24 mahina mai ka lā i hana ʻia ai i loko o ka pahu i wehe ʻole ʻia mua i mālama ʻia i kahi maloʻo a me kahi anuanu, mai ka lā pololei, ka wai.
Hale kūʻai ea, hoʻomaloʻo wela haʻahaʻa, hoʻokaʻawale ʻia mai nā mea hoʻomake a me nā waikawa.
