Muaj cov kuab tshuaj pov tseg tuaj yeem rov qab los rau hauv cov kuab tshuaj tshiab huv si los ntawm lub hauv paus ntsiab lus ntawm distillationhnyav rov qab tshuab. Txij li thaum muaj ntau yam kuab tshuaj nyob rau hauv kev lag luam, tom qab ib co kuab tshuaj tau zoo, cov residues nyob rau hauv cov kuab tshuaj rov qab tej kas tham yog nyuaj rau tu. Puas muaj kev daws teeb meem?
Thaum nrogkuab tshuaj distillationresidues uas yooj yim los lo rau ntawm phab ntsa thiab nyuaj rau ntxuav (xws li: number case muaj nyob rau hauv ethyl roj pov tseg kua hauv ntim cov nroj tsuag, luam ntawv kev lag luam, xim muaj nyob rau hauv rab phom ntxuav dej nyob rau hauv txheej kev lag luam, thiab lwm yam),hnyav rov qab hnabtuaj yeem yog ib qho kev pab zoo los daws qhov teeb meem no.
Kev ua haujlwm ntawm lub siab kub resistant rov qab hnab ntawm cov kuab tshuaj rov qab tshuab:
1. Ceev ceev cov khoom seem thiab txhim kho kev ua haujlwm;
2. Tiv thaiv lub thoob khib nyiab ntawm cov kuab tshuaj siv lub tshuab kom tsis txhob muaj kua qaub lossis alkaline cov kuab tshuaj los ntawm corroding lub tshuab thiab khoom siv;
3. Nws yuav tsis ua rau cov khoom siv rov ua dua tshiab vim muaj cov khoom siv rov ua dua tshiab vim kev ntxuav tsis huv;
Cov kauj ruam ntawm kev siv lub tshuab hnyav rov qab lub siab kub resistant rov qab hnab:
1. Qhib lub hau ntawm lub thoob, muab lub hnab ntim cov kuab tshuaj rov qab rau hauv lub thoob thiab siv cov khoom txhawb nqa los qhib nws;
2. Muab cov kuab tshuaj pov tseg uas yuav tsum tau muab tso rau hauv lub hnab rov ua dua tshiab hauv lub thoob;
3. Kaw lub hau npog thiab pib cov khoom siv rau cov kuab tshuaj rov qab raws li cov txheej txheem ua haujlwm ntawm lub tshuab hnyav;
4. Tom qab qhov kev rov qab ua tiav, qhib lub thoob lub hau thaum lub tshuab hnyav rov qab poob rau hauv chav tsev kub, tshem tawm cov txheej txheem txhawb nqa thiab nqa tawm lub hnab rov qab, thiab cov khoom seem rov qab tau yooj yim tshem tawm.
Covhnyav rov qab linerTsis tsuas yog tiv taus ntau yam kuab tshuaj, tab sis kuj tuaj yeem tiv taus qhov kub thiab txias hauv 240 degrees Celsius. Cia peb tshem tawm cov teeb meem ntawm kev ntxuav cov khoom seem hauv cov khoom siv rov ua dua txij li tam sim no.
