Kushanda uye Zvimiro：

Mishonga inoshandiswawo mukugadzira fiber treatment agent. Inoshandiswawo mukurapa kugadzira theophylline, caffeine uye nificaran hydrochloride.

Nzira dzekushandisa:

(1) gasi remethylamine rinopfuudzwa muurea yakanyungudutswa, uye gasi reammonia rinoburitswa rinonyungudutswa rodzorerwa. Kana chigadzirwa cherea chatonhodzwa, chinobviswa chodzokororwa.

(2) kabhoni dhayiokisaidhi yakagadzirwa negasi-solid catalytic reaction ne monomethylamine.

(3) maitiro emethyl isocyanate nemethylamine.

Pakeji uye Kuchengeta

Kurongedza nebhegi re25kg, kana Chengeta mumudziyo wekutanga chete munzvimbo inotonhorera ine mhepo yakanaka. Chengeta kure nezvinhu zvisingaenderane nazvo. Midziyo inovhurwa inofanira kucheneswa nekungwarirayakavharwazve uye yakachengetedzwa yakatwasuka kudzivirira kubuda kwemvura. Dzivisa nguva refu yekuchengeta.

Zvinyorwa
Ruzivo rwechigadzirwa nderwekutarisa, kutsvagisa uye kuzivikanwa chete. Hatizove nemhosva kana gakava repatent.
Kana muine mibvunzo nezve tekinoroji kana mashandisirwo, ndapota taurai nesu nenguva.
