Kagwiritsidwe Ntchito
Ntchito zazikulu za phenolphthalein: 1. Makampani opanga mankhwala ngati zinthu zopangira mankhwala: Ndi yoyenera kudzimbidwa kosalekeza komanso kosalekeza ndipo imapezeka m'njira zosiyanasiyana monga mapiritsi ndi ma suppositories. 2. Pakupanga kwachilengedwe: Imagwiritsidwa ntchito makamaka popanga mapulasitiki, makamaka popanga ma polima a diazazone polyaryletherketone. Ma polima awa ali ndi kukana kutentha bwino, kukana madzi, kukana dzimbiri kwa mankhwala, kukana kutentha kukalamba komanso kusinthasintha bwino. Ulusi, zokutira ndi zinthu zopangidwa kuchokera pamenepo zidagwiritsidwa ntchito posachedwa m'magawo monga zamagetsi ndi zida zamagetsi, zida zamakanika, zoyendera, ndege, uinjiniya wa mphamvu za atomiki ndi zankhondo. 3. Imagwiritsidwa ntchito ngati chizindikiro cha acid-base, chizindikiro cha titration ya yankho losakhala lamadzi, komanso reagent yowunikira chromatographic.
Mankhwalawa amagwiritsidwa ntchito kwambiri ngati asidi, ndipo amatha kusintha mtundu wa pH8.2 (wopanda utoto) -10.0 (wofiira). Phenolphthalein ndi mankhwala ena. Monga mankhwala ofewetsa ululu, amagwira ntchito m'matumbo ndipo amagwiritsidwa ntchito pochiza kudzimbidwa.
Amagwiritsidwa ntchito ngati chizindikiro cha acid-base komanso ngati chotsitsimula pochiza kudzimbidwa
Zizindikiro za asidi, zizindikiro za titration ya yankho losakhala lamadzi, ma reagents osanthula chromatographic.
Kulongedza ndi Kutumiza
25KG/Drum kapena malinga ndi zomwe makasitomala amafuna.
Ndi katundu wamba ndipo amatha kutumizidwa kudzera m'nyanja ndi mlengalenga
Sungani ndi kusunga
Nthawi yosungiramo zinthu: Miyezi 24 kuyambira tsiku lopangidwa m'maphukusi oyambirira osatsegulidwa, osungidwa pamalo ozizira komanso ouma, kutali ndi dzuwa, madzi.
Nyumba yosungiramo zinthu zopumira mpweya, Youma pang'ono, Yosiyana ndi ma oxidants, ma acid.
