Dimefluthrin, inodzinga zvipembenene nemutengo wakaderera

Tsananguro yeChigadzirwa

Mushonga wezvipembenene wepyrethroid unoshanda nesimba pakurwisa umhutu nezvimwe zvipembenene. Dimefluthrin yemhando yepamusoromushonga wezvipembeneneIine mvura yero kusvika brown yakasviba isina zvinhu zviri kunze kwemuviri, uye zvakare chinhu chinoshanda muzvinonhuwira zvinodzinga Mosquito Repellent. Inonyaradza marwadzo kana chepfu iri mucoil yeumhutuinoshandiswa kuraramisa kana kuchetura umhutu, nekuti mushonga wacho mudiki, saka kukuvadza munhu kudiki. Haina chepfu pamhuka dzinoyamwisa, uye haina zvayakaita paHutano Hweveruzhinji.

Kuwanikwa kwezviri mukati
Shandisa gas chromatography kuongorora zviri mu tetrafluoromethrin. Uchishandisa fenpropathrin se internal standard, DB-1 quartz capillary column separation uye FID detection. Mhedzisiro yekuongorora inoratidza kuti linear correlation coefficient ye tetrafluoromethyl ether Chemicalbook pyrethroid i0.9991, standard deviation i0.000049, coefficient of variation i0.31%, uye recovery rate iri pakati pe97.00% ne99.44%.

Kutariswa

Kana imba yacho ikapfutirwa nezvinonhuwira zvinodzinga umhutu kwenguva yakareba uye mhepo isingafambi zvakanaka, zvinogona kukonzera zviratidzo zvekuoma kwechipfuva nedzungu kuvakadzi vane pamuviri, kuderedza kufamba kwemwana ari mudumbu, uye kutokonzera kushaya simba kwemwana ari mudumbu. Saka, zvakanaka kuti vakadzi vane pamuviri vasashandise michina yekudzivirira umhutu.
