HANGANGA:
Whakaahuatanga:
He kakara riki kaha te dimethyl disulfide. Kāore e mimiti te wai. He mea whakamīharo, ahakoa he tokomaha e kite ana i tōna kakara kino i ngā kukū tiketike e ai ki te kōrero i runga ake nei, ina whakaranua, kua whakaahuatia hoki tōna kakara he mea reka. He maha te whakamahi i te dimethyl disulfide me ētahi atu matū kakara i roto i ngā hua kai, tae atu ki ngā kai tunutunu, te tiihi, ngā hua miraka tio, ngā hua mīti, ngā hupa, ngā kakara reka, ngā kakara hua, ngā monamona ngohengohe, te gelatin, ngā pūtini, me ngā inu waipiro me ngā inu kore waipiro.

Whakamahinga
I roto i te ahumahi, ka whakamahia hoki te Dimethyl disulfide hei matū whakapūkawa hei whakatere i ngā tauhohenga i roto i ngā whare hanga hinu me ētahi atu ahumahi. He iti te pāmahana mura o te 16 ℃ (61 °F) e tūpono ai te ahi i te wā e whakamahia ana te whare hanga hinu. Nā te kaha o te haunga me te iti o te pāmahana mura, me rongoa te Dimethyl disulfide i raro i te pēhanga hauota i roto i ngā ipu kati.
He kakara whanariki tō te dimethyl disulfide, he rite ki te kakara o te kāriki me ngā ika pirau. Nā te kakara motuhake o ngā matū whanariki, he rite ki te DMDS, ka tāpirihia pinepinetia ki te hau māori me te propane hei whakatūpato i ngā turuturu me te tiaki i te tangata. Nō reira, ka taea te pohehe i te kakara o te whakapūnga DMDS he turuturu hau. Ko te paepae kakara o te DMDS he tata ki te 7 ppb, he tata ki te 8 ngā wā iti iho i te taumata hauora e whakaarohia ana e te EPA he haumaru (55 ppb).
Ka whakamahia te dimethyl disulfide hei takawaenga, hei tāpiri kai hoki i roto i te riki, te kāriki, te tīhi, te mīti, te hupa, ngā kakara reka me ngā kakara hua. Ka whakamahia i roto i ngā whare hanga hinu hei kaihoko sulfiding. Ka whakamahia hei whakakapi i te 2-methylfuran-acrolein hei hanga kai. Kei roto i te hanga o te 4-(methylthio)phenol. Hei tāpiri, ka whakamahia hei whakakapi i te methyl mercaptan hei tāpiri wahie jet. Ka kitea te whakamahinga i roto i te kaihoko kakara horihori me te aukati waikura. Hei tāpiritanga ki tēnei, he pai te mahi hei whakakino oneone i roto i te ahuwhenua.
Tākai
200KG/Pahu, kia rite rānei ki ngā whakaritenga a te kiritaki.
Te pupuri me te rokiroki
Te roa o te oranga: 24 marama mai i te rā i hangaia ai, i roto i te takai taketake kāore anō kia whakatuwheratia, rongoatia ki te wāhi matao, maroke, ā, kāore e taea te ārai i te rā tika, i te wai rānei.
Whare putunga hauhautanga, Whakamaroke pāmahana iti, Wehea mai i ngā waikura me ngā waikawa.
