1. Tsarin Kwayoyin Halitta:
Ana samun ƙwayoyin cellulose daga cellulose, wani polymer da ke faruwa a zahiri wanda ake samu a bangon ƙwayoyin shuka. Ta hanyar gyaran sinadarai, kamar etherification, hydroxypropylation, ko carboxymethylation, ana samar da ƙwayoyin cellulose. Waɗannan gyare-gyaren suna gabatar da ƙungiyoyi masu aiki a kan kashin bayan cellulose, suna canza yadda yake narkewa da kuma hulɗa da sinadarai masu narkewa.
2. Narkewa da Kumburi:
Kwayoyin Cellulose suna da matakai daban-daban na narkewa a cikin ruwa da sinadarai masu narkewa na halitta, ya danganta da nau'in da matakin maye gurbinsu. A cikin tsarin shafawa, ƙwayoyin cellulose yawanci suna kumbura a cikin tsarin da ke tushen ruwa, suna samar da mafita mai laushi ko gels. Wannan yanayin kumburi yana ba da gudummawa ga tasirin kauri, yayin da sarƙoƙin polymer masu kumburi ke haɗuwa kuma suna hana kwararar sinadarin.
3. Haɗakar Hydrogen:
Haɗin hydrogen yana taka muhimmiyar rawa a cikin hulɗar da ke tsakanin cellulose ethers da ƙwayoyin ruwa ko wasu abubuwan da ke cikin shafi. Ƙungiyoyin hydroxyl da ke cikin cellulose ethers na iya samar da haɗin hydrogen tare da ƙwayoyin ruwa, suna haɓaka narkewa da kumburi. Bugu da ƙari, haɗin hydrogen yana sauƙaƙa hulɗa tsakanin cellulose ethers da sauran polymers ko barbashi a cikin tsarin rufewa, yana tasiri ga halayen rheological.
4. Gyaran Rheology:
