Magwiridwe antchito ndi zinthu zina：

Mankhwala ophatikizana, omwe amagwiritsidwanso ntchito popanga mankhwala ochizira ulusi. Amagwiritsidwa ntchito mu mankhwala kupanga theophylline, caffeine ndi nificaran hydrochloride.

Njira Zogwiritsira Ntchito:

(1) mpweya wa methylamine umalowetsedwa mu urea wosungunuka, ndipo mpweya wa ammonia wotulutsidwa umayamwa ndikubwezeretsedwa. Pambuyo poti mankhwalawo aziziritsidwa, amachotsedwa ndikubwezeretsedwanso.

(2) carbon dioxide inakonzedwa pogwiritsa ntchito mpweya wofanana ndi wolimba womwe umagwiritsidwa ntchito ndi monomethylamine.

(3) momwe methyl isocyanate imagwirira ntchito ndi methylamine.

Phukusi ndi Kusungirako

Kulongedza ndi thumba la 25kg, kapena Sungani m'chidebe choyambirira chokha pamalo ozizira komanso opumira bwino. Sungani kutali ndi zinthu zosagwirizana. Zidebe zomwe zatsegulidwa ziyenera kusamalidwa mosamala.Tsekaninso ndi kusunga choyimirira kuti musatuluke madzi. Pewani kusunga nthawi yayitali.

Zolemba
Chidziwitso cha malonda ndi cha kafukufuku, kufufuza ndi kuzindikira kokha. Sitidzakhala ndi udindo kapena mkangano wa patent.
Ngati muli ndi mafunso okhudza zaukadaulo kapena kugwiritsa ntchito, chonde titumizireni nthawi.
