Zithathe ukuziphendulela okuzeleko ukwanelisa zoke iimfuno zabathengi bethu; ukufikelela ituthuko eragela phambili ngokuvuma ukwanda kwabathengi bethu; uzokuba mlingani wokugcina wamakhasimende begodu ukhulise iinrhuluphelo zamakhasimende we-100% Original Propanoic Acid CAS 79-09-4 Propionic Acid, Solo kwasungulwa ekuthomeni kwabo-1990, nje sesibeke inethiwekhi yethu yokuthengisa e-USA, e-Germany, e-Asia, kanye namazwe amanengi we-Middle East. Sihlose ukuba mthengisi wezinga eliphezulu le-OEM ephasini loke kanye ne-aftermarket!
Zithathe ukuziphendulela okuzeleko ukwanelisa zoke iimfuno zabathengi bethu; ukufikelela ituthuko eragela phambili ngokuvuma ukwanda kwabathengi bethu; sizakuba mlingani wokugcina wokusebenzisana wamakhasimende begodu sikhulise iinrhuluphelo zamakhasimende, Sihlose ukuba libhizinisi lesimanjemanje elinemibono yezokuthengisa "yokuthembeka nokuzithemba" begodu ngenhloso "yokunikela amakhasimende ngeenkonzo eziqotho khulu nemikhiqizo esezingeni eliphezulu". Sibawa ngokusuka ehliziyweni isekelo lakho elingatjhugulukiko begodu siyathokoza ngesiyeleliso sakho esihle nesiqondiso sakho.
Iinkomba eziqakathekileko zekhwalithi ye-propionic acid yezinga lebubulo zilandelako:
Okuqukethwe kwe-esidi ye-propionic: ≥ 99.5% yebanga eliphezulu, ≥ 99.0% yebanga lokuthoma (okubekwa ngokulinganisa i-esidi-ibheyisi);
Umbala we-propionic acid (isikali seplatinamu-kobalt): ≤ 10 amayunithi we-Hazen webanga eliphezulu, ≤ 20 amayunithi we-Hazen webanga lokuthoma (ahlolwe ngokuya nge-GB/T 605);
I-propionic acid Okuqukethwe komswakama: ≤ 0.10% yebanga eliphezulu, ≤ 0.20% yezinga lokuthoma (okubekwa ngendlela ka-Karl Fischer);
Iinsalela zokuhwamuka: ≤ 0.01% yezinga eliphezulu, ≤ 0.03% yezinga lokuthoma (eliqunywa ngendlela ye-gravimetric ku-105°C);
Okuqukethwe kwe-iron (Fe): ≤ 0.0005% yebanga eliphezulu, ≤ 0.001% yebanga lokuthoma (okuqunywa nge-atomic absorption spectrometry);
I-propionic acid Iinsimbi ezisindako (njenge-Pb): ≤ 0.0005% yezinga eliphezulu, ≤ 0.001% yezinga lokuthoma (eliqunywa yi-thioacetamide colorimetry).
