Kev siv cov tshuaj Propionic acid

Propionic acid yog ib yam tshuaj zoo tseem ceeb thiab yog ib qho nruab nrab ntawm ntau lwm yam tshuaj zoo. Nws feem ntau yog siv ua cov khoom noj thiab cov khoom noj pub, ua raws li cov tshuaj ntsuab thiab tshuaj hauv tsev, cov txuj lom thiab lwm yam. Hauv kev lag luam ntawm cov nplej thiab cov khoom noj pub, cov txiaj ntsig ntawm kev siv propionic acid yog qhov zoo kawg nkaus, thiab kev noj tau nce sai. (1) Cov khoom noj ntxiv hauv qhov ncauj. Calcium propionate thiab sodium propionate tuaj yeem tiv thaiv kev puas tsuaj ntawm cov khoom noj los ntawm kev ua haujlwm ntawm cov kab mob me me, ncua sijhawm khaws cia khoom noj, thiab siv tau zoo hauv kev khaws cia cov mov ci thiab ncuav mog qab zib. (2) Cov tshuaj khaws cia nplej. Propionic acid tau siv tau zoo los tiv thaiv cov pwm thiab cov nplej tawg, uas muab txoj hauv kev tshiab rau kev khaws cia nplej ntev. (3) Cov tshuaj khaws cia dej haus. Nws tau ua pov thawj tias propionic acid, sodium propionate thiab calcium propionate yog cov tshuaj khaws cia khoom noj zoo, uas feem ntau yog siv los khaws cov khoom noj rau npua, nyuj, yaj thiab nqaij qaib, ntawm cov uas calcium propionate muaj cov txiaj ntsig zoo tshaj plaws. Zinc propionate thiab cadmium propionate hauv propionate yog cov tshuaj polyester catalysts rau kev tsim cov terephthalate. Muaj ntau hom propionate, nrog rau lawv tus kheej siv, tuaj yeem siv ua cov kuab tshuaj, tshuaj tsw qab, tshuaj nruab nrab, cov khoom siv pleev xim, cov khoom hloov kho resin, cov lim luam yeeb yas, cov roj roj antiknock agents, cov tshuaj tua kab mob thiab lwm yam.

Qhov zoo ntawm Propionic acid

1. Siab purity 99.0% feeb

2. Siv ntau yam saj.

3. Peb muaj daim ntawv pov thawj ISO 9001, ISO 14001 thiab ISO22000, Peb kuj muaj daim ntawv pov thawj HACCP, muaj daim ntawv pov thawj Halal thiab kosher ntawm cov khoom no.

5. Peb muaj peev xwm loj, yog li, feem ntau muaj lub sijhawm ua haujlwm sai.

6. Peb tuaj yeem muab 10g-50g qauv dawb rau koj qhov kev kuaj hauv chaw kuaj mob. Peb feem ntau xa cov qauv los ntawm tus neeg xa khoom thoob ntiaj teb xws li DHL lossis Fedex. Nws yog qhov ceev thiab yooj yim.

Kev ntim khoom ntawm Propionic acid

1. Cov qauv ntim yog 20g/30g/50g ib lub raj mis.

2. Lub pob me me yog 1kg / 5kg / 10 kg ib lub raj mis.

3.25 kg ib lub nruas (Noj zaub mov yas nruas, tsis muaj plasticizer, daim ntawv pov thawj thib peb)

Kev ntim khoom kuj tseem tuaj yeem hloov kho raws li cov neeg siv khoom xav tau

Cov xwm txheej khaws cia rau Propionic acid:

Kev Ceev Faj Txog Kev Khaws Cia Khaws cia rau hauv qhov chaw txias thiab muaj cua nkag. Khaws cia kom deb ntawm hluav taws thiab cua sov. Qhov kub ntawm qhov chaw khaws cia tsis pub tshaj 32 ℃, thiab qhov av noo tsis pub tshaj 80%. Khaws lub thawv kom kaw. Nws yuav tsum khaws cia cais ntawm cov tshuaj oxidants, cov tshuaj txo qis thiab alkalis, thiab yuav tsum tsis txhob sib xyaw. Siv cov teeb pom kev zoo thiab cov chaw ua pa uas tiv taus kev tawg. Tsis txhob siv cov khoom siv kho tshuab thiab cov cuab yeej uas yooj yim hluav taws. Qhov chaw khaws cia yuav tsum muaj cov khoom siv kho mob thaum muaj xwm txheej ceev thiab cov khoom siv tiv thaiv tsim nyog.
