Kumbukirani kuti "Kasitomala choyamba, Wabwino kwambiri choyamba", timagwira ntchito limodzi ndi ogula athu ndipo timawapatsa ntchito zothandiza komanso zapadera za 100% Original Organic Reagent, Plasticizer Einecs 201-176-3 Propionic Acid, Tikukulandirani kuti mudzagwirizane nafe kuti bizinesi yanu ikhale yosavuta. Nthawi zonse ndife bwenzi lanu labwino kwambiri mukafuna kukhala ndi bizinesi yanu.
Kumbukirani kuti “Kasitomala choyamba, Zabwino kwambiri choyamba”, timagwira ntchito limodzi ndi ogula athu ndipo timawapatsa ntchito zothandiza komanso zapadera. Purezidenti ndi mamembala onse a kampaniyo akufuna kupereka zinthu ndi ntchito zaukadaulo kwa makasitomala ndipo amalandira ndikugwirizana ndi makasitomala onse akumaloko ndi akunja kuti akhale ndi tsogolo labwino.
Chitetezo, Kusunga, ndi Kusamalira Propionic Acid
Kuti mugwiritse ntchito bwino, dziwani kuti malire ophulika a nthunzi ya propionyl acetic acid mumlengalenga ndi 1.2%–8.5% (v/v), ndipo malire ololedwa owonekera kuntchito ndi 15 mg/m³. Ngati patuluka madzi, kuyankha mwadzidzidzi kuyenera kugwiritsa ntchito yankho la 5% sodium bicarbonate kuti lichepetse kuipitsidwa; pewani kutsuka madzi, zomwe zingayambitse kufalikira kwa kuipitsidwa. Kafukufuku wa labotale akuwonetsa kuti LD50 yake ya pakamwa ndi 128 mg/kg (makoswe), ndipo chizindikiro chake cha kuyabwa pakhungu ndi 4.2. Magolovesi ndi magalasi oteteza mankhwala ayenera kuvalidwa pogwira ntchito.
Posungira ndi kunyamula, tsatirani malangizo a GB156-202. Iyenera kusungidwa m'zidebe zachitsulo zomangiriridwa, kutentha kwa nyumba yosungiramo zinthu kukhale pa 5–30°C komanso chinyezi chosapitirira 75%. Kusunga kwa nthawi yayitali kumafuna kuphimba nayitrogeni; kusintha kwa asidi kuyenera kuyesedwa kotala lililonse, ndipo kukonzanso nthawi yake kudzera mu distillation kumafunika ngati acidity ikukwera ndi kupitirira 0.5%. Magalimoto oyendera ayenera kukhala ndi zida zotsutsana ndi static, ndipo iyenera kulekanitsidwa ndi zinthu zamphamvu zosungunuka ndi zinthu zamchere ndi magawo osachepera atatu.
