Performance uye Features:

Pharmaceutical intermediates, inoshandiswawo mukugadzirwa kwefiber treatment agent.Inoshandiswa mumishonga kugadzira theophylline, caffeine uye nificaran hydrochloride.

Maitiro ekushandisa:

(1) iyo methylamine gasi inopfuudzwa mu yakanyungudutswa urea, uye yakaburitswa ammonia gasi inotorwa uye inodzoreredzwa. Mushure mokunge chigadzirwa chacho chatonhodzwa, chinotorwa kunze uye chakagadziridzwa zvakare.

(2) carbon dioxide yakagadzirwa negasi-solid catalytic reaction ne monomethylamine.

(3) kuita kwemethyl isocyanate ine methylamine.

Package uye Kuchengeta

Kurongedza nebhegi re25kg, kana kuti Chengetedza mugaba rekutanga chete munzvimbo inotonhorera inofefetera. Ramba kure nezvisingaenderani. Midziyo inovhurwa inofanirwa kuve nehungwaruyakavharwa patsva uye ikaramba yakati twasu kudzivirira kubuda. Dzivisa kuchengetwa kwenguva refu.

Notes
Ruzivo rwechigadzirwa nderwekureva, kutsvaga nekuzivikanwa chete.Hatizotakura mutoro kana gakava remvumo.
Kana iwe uine chero mibvunzo mune tekinoroji kana kushandisa, ndapota taura nesu munguva.
