Nan take/Slow Dissolving Cellulose Ether (Jiyya na saman)

Cellulose Ether Rarraba

Cellulose ether shine kalma na gaba ɗaya don jerin samfurori da aka samar ta hanyar amsawar alkali cellulose da etherifying wakili a ƙarƙashin wasu yanayi. Lokacin da aka maye gurbin alkali cellulose ta daban-daban etherifying jamiái, daban-daban cellulose ethers za a samu.

Dangane da kaddarorin ionization na masu maye, ana iya raba ethers cellulose zuwa kashi biyu: ionic (kamar carboxymethyl cellulose) da nonionic (kamar methyl cellulose).

Dangane da nau'in maye gurbin, ana iya raba ether cellulose zuwa monoether (kamar methyl cellulose) da ether gauraye (kamar hydroxypropyl methyl cellulose).

A cewar daban-daban solubility, shi za a iya raba zuwa ruwa solubility (kamar hydroxyethyl cellulose) da Organic sauran ƙarfi solubility (kamar ethyl cellulose).

Ethers cellulose mai narkewa da ruwa da aka yi amfani da su a cikin busassun busassun turmi sun kasu kashi-kashi-narke da jinkirin jinkiri-narkar da ethers cellulose.

Ina bambance-bambancen su? Kuma ta yaya za a daidaita shi da kyau a cikin maganin ruwa na 2% don gwajin danko?

Menene maganin saman?

Tasiri akan ether cellulose?

na farko

Maganin saman hanya hanya ce ta wucin gadi ta samar da shimfidar wuri a saman wani abu mai tushe tare da kayan aikin injiniya, na zahiri da sinadarai daban-daban da na tushe.

Manufar saman jiyya na cellulose ether shi ne jinkirta lokacin hada cellulose ether da ruwa don saduwa da jinkirin thickening bukatun wasu fenti, da kuma ƙara lalata juriya na cellulose ether da inganta ajiya kwanciyar hankali.

Bambanci lokacin da aka saita ruwan sanyi tare da maganin ruwa na 2%:

Ether na cellulose da aka yi masa magani zai iya watse da sauri a cikin ruwan sanyi kuma ba shi da sauƙin haɓakawa saboda jinkirin danko;

Cellulose ether ba tare da magani na sama ba, saboda saurin danko, zai zama danko kafin a tarwatsa shi gaba daya a cikin ruwan sanyi, kuma yana da haɗari ga haɓakawa.

Yadda za a saita ether cellulose da ba a kula da shi ba?

1. Da farko sanya a cikin wani adadin cellulose ether wanda ba a kula da shi ba;

2. Sa'an nan kuma ƙara ruwan zafi a kimanin digiri 80, nauyin nauyin shine kashi ɗaya bisa uku na adadin ruwan da ake bukata, ta yadda zai iya kumbura kuma ya watse;

3. Na gaba, sannu a hankali zuba cikin ruwan sanyi, nauyin shine kashi biyu cikin uku na sauran ruwan da ake buƙata, ci gaba da motsawa don yin shi a hankali a hankali, kuma ba za a sami raguwa ba;

4. A ƙarshe, a ƙarƙashin yanayin daidaitaccen nauyi, saka shi a cikin wanka na ruwa mai zafi har sai yawan zafin jiki ya ragu zuwa digiri 20 na Celsius, sa'an nan kuma za'a iya yin gwajin danko!
