Menene bambanci tsakanin cellulose ether da cellulose?

Cellulose da cellulose ether duk an samo su ne daga cellulose, wani polymer na halitta da ke samuwa a cikin ganuwar tantanin halitta. Koyaya, suna da bambance-bambance daban-daban a tsarin sinadarai da kaddarorinsu:

1. Tsarin Sinadarai: Cellulose shine polysaccharide madaidaiciya wanda ya ƙunshi maimaita raka'o'in glucose wanda aka haɗa tare da β(1→4) glycosidic bonds. Yana da madaidaicin sarkar polymer tare da babban matakin crystallinity.
2. Hydrophilicity: Cellulose yana da asali na hydrophilic, ma'ana yana da alaƙa mai ƙarfi ga ruwa kuma yana iya ɗaukar danshi mai yawa. Wannan kadarar tana rinjayar halayenta a aikace-aikace daban-daban, gami da hulɗar ta tare da tsarin tushen ruwa kamar gauran siminti.
3. Solubility: Tsaftataccen cellulose ba shi da narkewa a cikin ruwa kuma galibin abubuwan kaushi na kwayoyin halitta saboda tsarinsa na crystalline sosai da babban haɗin gwiwar hydrogen tsakanin sarƙoƙi na polymer.
4. Derivatization: Cellulose ether wani gyaggyarawa nau'i ne na cellulose samu ta hanyar sinadari derivatization. Wannan tsari ya ƙunshi gabatar da ƙungiyoyi masu aiki, irin su hydroxyethyl, hydroxypropyl, methyl, ko ƙungiyoyin carboxymethyl, akan kashin bayan cellulose. Wadannan gyare-gyare suna canza kaddarorin cellulose, gami da solubility, halayen rheological, da hulɗa tare da wasu abubuwa.
5. Solubility a cikin Ruwa: Cellulose ethers yawanci suna narkewa ko kuma za'a iya rarraba su cikin ruwa, ya danganta da takamaiman nau'in da matakin maye gurbin. Wannan solubility yana sa su amfani sosai a masana'antu daban-daban, gami da magunguna, abinci, kayan kwalliya, da gini.
6. Aikace-aikace: Cellulose ethers sami tartsatsi aikace-aikace a matsayin thickening jamiái, stabilizers, binders, da kuma film-forming jamiái a cikin bambancin kewayon samfurori da matakai. A cikin ginin, ana amfani da su azaman ƙari a cikin kayan tushen siminti don haɓaka iya aiki, riƙe ruwa, mannewa, da sauran kaddarorin.

A taƙaice, yayin da cellulose da cellulose ether ke raba asali na kowa, cellulose ether an gyare-gyare ta hanyar kimiyya don gabatar da takamaiman kaddarorin da ke sa shi mai narkewa ko yaduwa a cikin ruwa kuma ya dace da aikace-aikace daban-daban inda ake son iko akan halayen rheological da hulɗa tare da wasu abubuwa.
