Properties:

EDTMA chena crystal poda pakamuri tembiricha, ine melting point 215-217 ℃, yakaoma kunyungudutswa mumvura, solubility ishoma kusvika 5% pakupisa kwekamuri, kunyungudika nyore muammonia. EDTMA ine simbi yakasimba ion chelating capacity, iyo chelating inogara ine cuprum ion yakakura kupfuura iyo yeEDTA.

EDTMPA ndeyekuchena kwepamusoro kusiri-chepfu reagent, ine simba rakasimba chelating yesimbi ions, iyo inogona kushandiswa muindasitiri yemagetsi semugadziri wekuchenesa semiconductor machipisi emasekete akabatanidzwa, uye semutakuri weradioactive zvinhu muindasitiri yemishonga yekuona. uye kurapwa kwezvirwere.

Tsanangudzo:

Kambani yedu inogona kugadzira 99% (chromatograph kuchena) uye yakakwira kuchena chigadzirwa pakuda kwevatengi.

Kurongedza uye kuchengetedza:

EDTMPA yakazara mumadhiramu epurasitiki, 25kg padhiramu kana sekutemerwa nezvinodiwa nemushandisi. Chengetedza munzvimbo inotonhorera mukati, nguva yekuchengetedza mwedzi gumi.

Chengetedzo nekudzivirira:

EDTMPA haina kusimba alkaline. Ngwarira kuchengetedzwa kwebasa panguva yekushanda. Dzivisa kusangana nemaziso uye ganda. Kana uchinge wasangana, sukurudza pakarepo nemvura yakawanda.
