(1)Polycarboxylate dej reducer muaj ntau cov as-ham rau kev ciaj sia ntawm cov kab mob thiab lwm yam kab mob. Qhov kub siab dua, nws yooj yim dua rau cov kab mob me me, thiab qhov ceev cov khoom xyaw hauvpolycarboxylate dej reducer yog siv. Thaum tsis muaj preservatives, thaum lub ambient kub siab tshaj 25℃thiab khaws cia rau 7 hnub, thiab thaum lub ambient kub nyob ib ncig ntawm 10℃thiab khaws cia rau 28 hnub, cov kab mob cov ntsiab lus yog nyob rau theem ntawm 10cfu / ml. Lub sijhawm no, cov pob zeb muaj qhov poob loj dhau sijhawm thiab lub sijhawm teem sijhawm luv luv.

(2) Cov tshuaj tiv thaiv kev tshaj lij lossis sodium metabisulfite hauv khw muaj cov kab mob zoo thiab tshuaj tua kab mob, thiab 1‰yog ntxiv. Cov kab mob cov ntsiab lus ntawm cov dej reducer nrog preservatives yog <10cfu / ml tom qab khaws cia ntawm 9-15℃rau 28 hnub, thiab 5% ntxiv. Cov kab mob cov ntsiab lus ntawm cov dej reducer nrog sodium metabisulfite yog 10-100cfu / ml tom qab khaws cia ntawm 9-15℃rau 28day. Lub pob zeb muaj ib txwm poob thaum lub sijhawm thiab teeb tsa lub sijhawm. Yog li ntawd, txhawm rau tiv thaiv covpolycarboxylate dej reducer los ntawm lwj thaum lub sij hawm cia, ntxiv preservatives yog ib txoj kev zoo.

(3)Raws li kev sib tw antiseptic xeem ntawmpolycarboxylate dej reducer, thaum qhov sib ntxiv ntawm ob qho tshuaj tiv thaiv yog 2%, cov ntsiab lus ntawm cov kab mob thaum lub sij hawm tag nrho cov tshuaj tua kab mob sib tw yog <10cfu/ml; thaum tus nqi ntxiv ntawm preservative yog 1‰, cov kab mob suav ntawm covpolycarboxylate Cov dej txo qis nrog qhov sib ntxiv ntawm preservative E16 pib nce tom qab 21 hnub, thiab cov kab mob suav nrogpolycarboxylate dej reducer nrog ntxiv ntawm preservative 02F pib nce tom qab 7 hnub, qhia tias cov kab mob thiab cov tshuaj tua kab mob muaj peev xwm ntawm cov tshuaj tua kab mob sib txawv. Yog li ntawd, qhov tseeb hom thiab tus nqi ntawm cov tshuaj preservatives ntxiv yuav tsum tau txiav txim siab los ntawm kev sim raws li cov kev cia tshwj xeeb thiab lub sijhawm.
