Ukusetshenziswa
Ukusetshenziswa okuyinhloko kwe-phenolphthalein: 1. Imboni yezemithi njengezinto zokusetshenziswa kwezokwelapha: Ifanelekela ukuqunjelwa okuvamile nokuphikelelayo futhi itholakala ngezindlela ezahlukene zomthamo njengezibhebhe nama-suppositories. 2. Ukwenziwa kwezinto eziphilayo: Isetshenziswa kakhulu ekuhlanganisweni kwepulasitiki, ikakhulukazi ekuhlanganisweni kwama-polymer e-diazazone polyaryletherketone. Lawa ma-polymer anokumelana okuhle kakhulu nokushisa, ukumelana namanzi, ukumelana nokugqwala kwamakhemikhali, ukumelana nokuguga kokushisa kanye nokucutshungulwa okuhle kanye nokwakheka. Ama-fiber, izembozo nezinto ezihlanganisiwe ezenziwe ngawo zasheshe zasetshenziswa kabanzi emikhakheni efana ne-elekthronikhi nemishini kagesi, imishini yemishini, ezokuthutha, izindiza, ubunjiniyela bamandla e-athomu kanye nezempi. 3. Isetshenziswa njengesibonakaliso se-acid-base, isibonakaliso se-titration yesisombululo esingeyona i-aqueous, kanye ne-reagent yokuhlaziywa kwe-chromatographic.
Lo mkhiqizo uyi-ejenti ye-acid index esetshenziswa kakhulu, enebanga lokushintsha kombala elingu-pH8.2 (elingenambala) -10.0 (elibomvu). I-Phenolphthalein nayo iwuhlobo lomuthi. Njengomuthi wokuhlanza, isebenza emathunjini futhi isetshenziselwa ukwelapha ukuqunjelwa.
Isetshenziswa njengesibonakaliso se-acid-base kanye nesivuseleli sokuhlanza isisu ekwelapheni ukuqunjelwa
Izinkomba zesisekelo se-asidi, izinkomba ze-titration yesisombululo esingesona samanzi, ama-reagent okuhlaziya i-chromatographic.
Ukupakisha Nokuthumela
25KG/Isigubhu noma ngokwezidingo zamakhasimende.
Kungokwempahla evamile futhi kungathunyelwa ngolwandle nangomoya
Gcina futhi ugcine
Isikhathi sokuphila: Izinyanga ezingama-24 kusukela ngosuku lokwenziwa kwento epakishweni lokuqala elingavulwanga, igcinwe endaweni epholile neyomile kude nokukhanya kwelanga okuqondile, amanzi.
Indawo yokugcina izinto enomoya, Ukomisa okuphansi kwezinga lokushisa, Ihlukaniswe nama-oxidants, ama-acid.
