1. Kev ua cov tshuaj dilution thiab cov tshuaj noj:
Kev npaj dej cawv niam: 99% TC tau yaj rau hauv me me ntawm ethanol lossis alkali liquor (xws li 0.1% NaOH), thiab tom qab ntawd dej tau ntxiv rau kom dilute rau lub hom phiaj concentration.
Cov qauv tshuaj uas siv ntau:
Tshuaj tsuag nplooj: ua tiav rau hauv 0.1-0.5% AS lossis WP.
Kev ywg dej rau hauv paus: 0.05-0.1% SL.
2. Kev muaj qoob loo thiab zaus cog qoob loo:
| Hom qoob loo | Siv cov concentration | Hom kev siv | Zaus | Lub sijhawm tseem ceeb |
| Txiv hmab txiv ntoo thiab zaub (txiv lws suav/txiv pos nphuab) | 50-100 ppm | Tshuaj tsuag nplooj | 7-10 hnub ntawm lub sijhawm sib nrug, 2-3 zaug | Qib sib txawv ntawm cov paj tawg / 7 hnub ua ntej muaj teeb meem |
| Teb (nplej/mov) | 20-50 ppm | Kev ywg dej rau hauv paus | 1 zaug | theem thickening/ua ntej nthwv dej txias ceeb toom ua ntej |
| Cov ntoo txiv hmab txiv ntoo (txiv apples / txiv kab ntxwv) | 100-200 ppm | Ceg ntoo daub | 1 zaug | Kev khaws cia tom qab sau qoob loo lossis kho qhov raug mob khov |
3. Kev txwv thiab kev sib xyaw:
Tsis txhob sib xyaw nrog cov tshuaj tooj liab (xws li Bordeaux sib tov) lossis cov tshuaj tua kab mob uas muaj zog heev, uas yuav yooj yim los nag.
Tua tawm thaum kub siab (> 35℃) los yog lub teeb muaj zog, kom tsis txhob hlawv cov hniav.
