Cov lus qhia
Thaum siv BG-2680-80P, cov kuab tshuaj xws li propylene glycol methyl ether acetate (PMA) thiab propylene glycol diacetate (PGDA) tuaj yeem ntxiv rau dilution. Nws raug nquahu kom siv ammonia ester qib cov kuab tshuaj (nrog cov ntsiab lus ntawm cov dej tsawg dua 0.05%) rau kev dilution, nrog cov ntsiab lus tsis tsawg dua 40%. Ua cov kev sim tshwj xeeb ua ntej siv thiab ntsuas kev ruaj ntseg. Cov sib tov ntxiv nrog BG-2600-100 yuav tsum tau siv thaum lub sijhawm ua kom tiav.
khaws cia
Cov khoom yuav tsum tau muab cia rau hauv lub thawv kaw kom tsis txhob khov thiab kub. Nws raug nquahu kom khaws cov ntim ntim kom zoo ntawm qhov ntsuas kub ntawm 5-35 ℃. Lub txee lub neej ntawm cov khoom yog kaum ob lub hlis txij li hnub tsim khoom. Tom qab lub txee lub neej dhau lawm, nws raug nquahu kom ua qhov kev ntsuam xyuas ua ntej siv.
Cov khoom yog rhiab heev rau cov dej noo thiab reacts nrog dej los tsim cov pa roj carbon dioxide thiab urea, uas tuaj yeem ua rau lub thawv siab nce thiab ua rau muaj kev phom sij. Tom qab qhib lub ntim, nws raug nquahu kom siv nws sai li sai tau.
