Cellulose Ether Mai Narkewa Nan Take/A Hankali (Maganin Sama)

Rarraba Cellulose Ether

Cellulose ether kalma ce ta gabaɗaya ga jerin samfuran da aka samar ta hanyar amsawar alkali cellulose da wakilin etherifying a ƙarƙashin wasu yanayi. Lokacin da aka maye gurbin alkali cellulose da sinadarai daban-daban na etherifying, za a sami nau'ikan cellulose ethers daban-daban.

Dangane da halayen ionization na abubuwan maye, ana iya raba ethers na cellulose zuwa rukuni biyu: ionic (kamar carboxymethyl cellulose) da nonionic (kamar methyl cellulose).

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

Dangane da bambancin narkewar ruwa, ana iya raba shi zuwa narkewar ruwa (kamar hydroxyethyl cellulose) da kuma narkewar ruwa ta halitta (kamar ethyl cellulose).

Ana raba ƙwayoyin cellulose masu narkewa cikin ruwa a cikin turmi mai gauraye da busassun gauraye zuwa ƙwayoyin cellulose masu narkewa cikin sauri da kuma waɗanda aka yi musu magani da wuri.

Ina bambance-bambancensu suke? Kuma ta yaya za a daidaita shi cikin sauƙi zuwa ruwan da ke ɗauke da kashi 2% na ruwa don gwajin ɗanko?

Menene maganin saman jiki?

Tasiri akan cellulose ether?

na farko

Maganin saman hanya ce ta ƙirƙirar wani Layer na saman abu ta hanyar wucin gadi tare da halayen injiniya, na zahiri da na sinadarai daban-daban da na tushe.

Manufar maganin cellulose ether a saman shine a jinkirta lokacin haɗa cellulose ether da ruwa don biyan buƙatun kauri a hankali na wasu turmi fenti, da kuma ƙara juriyar tsatsa na cellulose ether da inganta kwanciyar hankali na ajiya.

Bambancin da ke tsakanin ruwan sanyi da ruwan da aka tace da kashi 2% na ruwan:

Sinadarin cellulose ether da aka yi wa magani a saman ruwa zai iya warwatse cikin ruwan sanyi da sauri kuma ba shi da sauƙin taruwa saboda jinkirin da yake da shi;

Cellulose ether ba tare da maganin saman ba, saboda saurin ɗigonsa, zai yi ƙauri kafin ya warwatse gaba ɗaya a cikin ruwan sanyi, kuma yana iya haɗuwa.

Yadda za a saita cellulose ether wanda ba a yi masa magani a saman ba?

1. Da farko a saka wani adadin cellulose ether wanda ba a yi masa magani a saman ba;

2. Sai a zuba ruwan zafi a kimanin digiri 80 na Celsius, nauyin shine kashi ɗaya bisa uku na yawan ruwan da ake buƙata, don ya kumbura gaba ɗaya ya kuma watse;

3. Na gaba, a zuba ruwan sanyi a hankali, nauyinsa ya kai kashi biyu bisa uku na sauran ruwan da ake buƙata, a ci gaba da juyawa don ya manne a hankali, kuma ba za a sami taruwa ba;

4. A ƙarshe, a ƙarƙashin yanayin daidai gwargwado, a saka shi a cikin ruwan wanka mai yawan zafin jiki har sai zafin ya faɗi zuwa digiri 20 na Celsius, sannan za a iya yin gwajin ɗanko!
