Cov chaw teeb tsa rau cov tshuab xa tawm siab hauv kab yuav tsum tau xaiv nrog kev tsom mus rau qhov tseem ceeb ntawm cov txheej txheem thiab kev pheej hmoo ntawm kev txhaws. Cov chaw tseem ceeb suav nrog cov kav dej pub thiab cov chaw tso tawm - qhov twg xav tias yuav muaj kev hloov pauv ntawm cov concentration - nrog rau ze ntawm cov cheeb tsam siab uas ua rau cov dej nag tsis huv sai dua. Kev tso cov tshuab xa tawm ua ntej thiab tom qab cov twj tso kua mis tseem ceeb tso cai rau kev saib xyuas qhov sib txawv ntawm lub siab, ua rau nws muaj peev xwm nrhiav tau qhov chaw tsim kev thaiv lossis nrhiav pom cov dej ntws tsis zoo uas tshwm sim los ntawm cov gypsum theem thaum ntxov. Cov kev coj ua zoo tshaj plaws no rau kev ua haujlwm ntawm cov nroj tsuag chiv phosphate pab tswj kev saib xyuas tas mus li ntawm ob qho tib si kev ua haujlwm zoo thiab kev nyab xeeb.
5. Cov cuab yeej twg ntxiv uas yuav tsum tau siv nrog cov tshuab xa tawm siab hauv kev tsim cov phosphoric acid uas ntub dej?
Ib txoj kev siv cov cuab yeej ua tiav ua ke nrog cov khoom siv xa tawm siab nrog cov ntsuas inline concentration, density, viscosity, level, thiab kub. Qhov kev teeb tsa ntau yam no txhim kho kev tswj hwm txheej txheem, ua rau muaj kev hloov kho kom raug ntawm txhua theem - xws li kev tswj hwm nruj thaum lub sijhawm muab kua qaub lossis kev saib xyuas lub sijhawm tiag tiag ntawm kev tswj hwm cov khoom lag luam calcium sulfate dihydrate. Piv txwv li, Lonnmeter's inline density thiab viscosity meters muab cov ntaub ntawv tseem ceeb ntawm kev sib xws ntawm slurry, ua kom tiav cov qauv siab rau kev daws teeb meem siab heev ntawm kev txhaws ntawm cov khoom tsis huv. Thaum siv ua ke, cov cuab yeej no tsim ib lub kaw lus holistic uas ua rau muaj kev ntseeg siab tshaj plaws, kev nyab xeeb ua haujlwm, thiab kev tsim cov chiv monoammonium phosphate siab.
