Ukusebenza kanye nezici：

Imithi ephakathi, esetshenziswa futhi ekukhiqizweni kwe-fiber treatment agent. Isetshenziswa kwezokwelapha ukuhlanganisa i-theophylline, i-caffeine kanye ne-nificaran hydrochloride.

Izindlela Zokusebenzisa:

(1) igesi ye-methylamine idluliselwa ku-urea encibilikisiwe, bese igesi ye-ammonia ekhishwe iyamuncwa futhi ibuyiselwe. Ngemva kokuba umkhiqizo wokusabela usupholile, uyakhishwa bese uphinda ufakwe i-crystal.

(2) i-carbon dioxide yalungiswa nge-gas-solid catalytic reaction ne-monomethylamine.

(3) ukusabela kwe-methyl isocyanate ne-methylamine.

Iphakheji kanye nesitoreji

Ukupakisha ngesikhwama esingama-25kg, noma Gcina kuphela esitsheni sokuqala endaweni epholile enomoya omuhle. Gcina kude nezinto ezingahambisani. Izitsha ezivuliwe kumele ziqashelwe ngokucophelelavala kabusha futhi igcinwe iqonde phezulu ukuze kuvinjelwe ukuvuza. Gwema isikhathi eside sokugcina.

Amanothi
Ulwazi lomkhiqizo luwukubhekisela, ucwaningo kanye nokuhlonza kuphela. Ngeke sithwale umthwalo wemfanelo noma impikiswano yelungelo lobunikazi.
Uma unemibuzo mayelana nobuchwepheshe noma ukusetshenziswa, sicela uxhumane nathi ngesikhathi.
