Mankhwala Ophera Tizilombo a Tetramethrin Udzudzu 95% Tc Kulamulira Udzudzu Ntchentche Ntchentche

Tetramethrin imagwiritsidwa ntchito kwambiri ngati mankhwala amphamvu.zopangidwaMankhwala ophera tizilombomu banja la pyrethroid. Ndi crystalline solid yoyera. Chogulitsachi ndi chisakanizo cha stereoisomers. Chimagwiritsidwa ntchito kwambiri ngatimankhwala ophera tizilombondipo zimakhudza mitsempha ya tizilombo. Imapezeka m'malo ambiriMankhwala Ophera Tizilombo Pakhomozinthu.Fomula yoyesera ndi C19H25NO4; kulemera kwa molekyulu ndi 331.4. Kapangidwe kake ndi kristalo wopanda mtundu; mphamvu yake yokoka ndi 1.1 pa 20°C; kuthamanga kwake kwa nthunzi ndi 0.944 mPa pa 30°C; logKow= 4.6. Sisungunuka kwambiri (1.83 mg/l) m'madzi pa 25°C, koma imasungunuka m'zinthu zambiri zachilengedwe. Siikhazikika m'zinthu zamphamvu za asidi ndi alkaline.

Kugwiritsa ntchito

Liwiro lake lotha kupha udzudzu, ntchentche ndi zina ndi lachangu. Limathandizanso kuthamangitsa mphemvu. Nthawi zambiri limapangidwa ndi mankhwala ophera tizilombo amphamvu kwambiri. Likhoza kupangidwa kukhala mankhwala ophera tizilombo opopera ndi mankhwala ophera tizilombo opangidwa ndi aerosol.

Kuopsa kwa poizoni

Tetramethrin ndi mankhwala ophera tizilombo omwe ali ndi poizoni wochepa. LD50 yoopsa kwambiri m'thupi mwa akalulu>2g/kg. Palibe zotsatira zoyipa pakhungu, maso, mphuno, ndi njira yopumira. Pansi pa zochitika zoyeserera, palibe zotsatira zoyipa za mutagenic, carcinogenic, kapena kubereka zomwe zidawonedwa.
