Tambayoyin da ake yawan yi (FAQs)

Tambayoyi gama gari game da HEC CAS 9004-62-0:

Q1: Menene bambanci tsakanin HEC da sauran ethers cellulose (misali, HPMC, MC)?

A: HEC yana da cikakken narkewa a cikin ruwan sanyi da ruwan zafi (babu gelation thermal), yayin da HPMC / MC gel lokacin zafi. HEC yana da mafi kyawun riƙewar ruwa da aikin colloid mai karewa fiye da MC, kuma ya fi ƙarfin dacewa da electrolytes fiye da HPMC.

Q2: Yadda za a narkar da HEC ba tare da clumping?

A: Mix HEC tare da inert foda (1: 5-1: 10) don tsarma, sa'an nan kuma a hankali ƙara zuwa motsawar ruwan sanyi (≥200 rpm) har sai an narkar da shi sosai. Za'a iya ƙara HEC da aka gyara a saman kai tsaye zuwa ruwan sanyi tare da motsawa.

Q3: Menene rayuwar rayuwar HEC da hanyar ajiya?

A: Rayuwar rayuwa wata 24 ce. Ajiye a cikin sanyi, bushe, wuri mai iska (RH ≤60%), marufi da aka rufe, nesa da zafi, haske da danshi. Ka guji hadawa da karfi acid/alkalis.

Q4: Shin HEC lafiya ne don abinci da amfani da magunguna?

A: iya. HEC ba mai guba ba ce, ba ta da haushi, tana bin ka'idodin FDA da WHO, kuma ana iya amfani dashi azaman mataimaki a masana'antar abinci da magunguna.

Q5: Za a iya daidaita danko da digiri na HEC?

A: iya. Dangantaka (50-100,000 mPa·s) da digiri na maye gurbin (1.5-2.5) ana iya keɓance su don saduwa da takamaiman bukatun masana'antu.

Q6: Menene daidaitaccen marufi na HEC?

A: Standard: 25kg / jaka (jakar da aka saka da danshi tare da PE liner). Marufi na al'ada (1kg / 5kg / 10kg) yana samuwa.

Q7: Shin HEC ya dace tare da mafita na electrolyte?

A: iya. Halin da ba na ionic na HEC ba ya sa ya dace da manyan hanyoyin samar da wutar lantarki, dace da aikace-aikace tare da gishiri ko surfactants.
