Txhawj tias nyob rau hauv daim phiaj 2015 ntawm lub Chinese Pharmacopoeia, Luj 0633, lub luj thib ob qhia tib neeg txoj cai los muab ntau yam cellulose.
Qhov IVS800 Ubbelohde Viscosity Meter Chav Ntawv Tshwj In, tsim los ntawm qhov Ubbelohde viscometer ua chav tsev, txhawj xeeb raws standards zoo li ISO, GB, thiab DIN. Nws pab tau qhov kev kawm tshwj in tshwj siab, xws li kev ntaus tshuab, kev ntsuas, kev sau pob, kev saj ntsuas, kev tshem tsha, thiab kev saum npo taws rau hauv dej. Qhov sijhawm pom tshwm meej heev tuaj yeem ncav cuag 0.001 feeb. Nws muab ib qho sib txawv zoo ib yam thiab sib piv rau qhov kub tshaj tshuaj, uas muaj qhov sib txawv ≤±0.01℃ rau kev kawm, kom paub meej tias cov ntaub ntawv kawm yog meej.
Kev Txheeb Xyuas
1. Kawm
Kawm tsoom tshuab nrog tshuab kawm muaj precision ntawm ib hlis ob pli thiab sau tso hauv daim phial tsoom. Siv DP25 tshuab tso dej siv dej tso hauv daim phial tsoom.
2. Siv Dej
Sau daim phial tsoom rau hauv Zhongwang Polymer Dissolver P12 thiab siv dej raws li kub thiab xim tshiab.
3. Kev Txheeb Xyuas Viscosity
Tshaj tiv thaiv IVS800 thiab nruj qhov chaw nkag ntawm dej. Tsg lub pob tsho los ntawm P12 dissolver thiab sau rau hauv lub thawv khib nyiab ntawm lub tiv thaiv. Muab software mus tshaj kom pib tsim kho thiab test.
4. Qhov teeb meem ntawm kev test
Qhov teeb meem yog qhov uas raug sau nrog sib npaug.
5. Sauv lub Ubbelohde Viscometer
Sauv nrog tshuab, sauv nrog tshuab tso, thiab sauv nrog tshuab txias.
