Cov Lus Qhia Ceev

Cov Lus Qhia Txog Kev Noj Qab Haus Huv Cov neeg mob uas mob ua pa nyuaj yuav tsum tsis txhob ua txoj haujlwm no. [1]

Kev nyab xeeb thiab kev tiv thaiv kev ua haujlwm

(1) Engineering tswj kev tswj lub kaw lus thiab lub qhov cua.

(2) Kev tiv thaiv kev tiv thaiv hluav taws thiab tawg: tiv thaiv cov nplaim hluav taws. Kev tua hluav taws thiab kev tua hluav taws: siv cov tshuaj tsuag dej, carbon dioxide, hmoov qhuav, hmoov npuas tsim nyog tua hluav taws.

(3) Kev ceev faj rau kev khaws cia thiab kev thauj mus los: Khaws rau hauv chav tsev txias, tso pa tawm. Khaws nyias los ntawm oxidizer.

(4) Kev tiv thaiv tus kheej: Kev tiv thaiv qhov cua, pa hauv zos. Kev tiv thaiv tawv nqaij: Hnav cov hnab looj tes tiv thaiv thiab tiv thaiv khaub ncaws. Qhov muag tiv thaiv: Coj kev ruaj ntseg looj tsom iav. Kev tiv thaiv kev txhaj tshuaj: Tsis txhob noj, haus lossis haus luam yeeb thaum ua haujlwm. Cov txheej txheem kev lag luam tsim tawm los ntawm kev ua kom tiav ntawm N, N-dimethylaniline thiab formaldehyde, distillation, crystallization thiab purification, sulfur, ammonization ntawm urea thiab ammonium chloride ntawm 150-160 ℃, lim thiab ziab ntawm cov khoom tiav. Kev noj cov khoom nyoos (kg, t) N, N-dimethylaniline (98%) 110 formaldehyde (37%) 460 urea 700 sulfur (99%) 350 ammonium chloride 630 p-aminobenzenesulfonic acid (100%)
