Asali dabaru da rarrabuwa na sel

Selel eth eth eth ether ne mai son polymers da aka samo daga sel, a zahiri yana faruwa a cikin polysaccharide polysaccharide da aka samo a jikin bangon shuka. Cellulose evers ana amfani da shi sosai a cikin masana'antu daban-daban saboda abubuwan musamman na musamman, wanda ya haɗa da thickening, riƙewar ruwa, fim-forming, da kuma daidaita iyawa. Ga ainihin abubuwan tunani da rarrabuwa na sel Elther:

Amincewa na asali:

1. Tsarin silli:
   • Cellulose ya ƙunshi maimaita relucose relucose rumbun da aka haɗa tare β (1 → 4) shaidu na glykisidic. Yana siffanta tsawon lokaci, sarƙoƙi na layi wanda ya ba da tallafin tsari don shuka sel.
2. ERITY:
   • PRELUOSE Ana samar da 3
3. Aiki:
   • The introduction of ether groups alters the chemical and physical properties of cellulose, giving cellulose ethers unique functionalities such as solubility, viscosity, water retention, and film formation.
4. Biodigradity:
   • Pheruloos Ethers sune polyragable polymers, ma'ana ana iya rushewa da ƙananan ƙwayoyin cuta a cikin muhalli, suna haifar da samuwar samfuran samfuran.

Rarrabuwa:

Cellulose Celuluna ana rarraba shi ne gwargwadon nau'ikan kungiyoyin ether da aka gabatar a kan kwayoyin siyar da selulose da kuma yanayinsu. Nau'in nau'ikan celulose sun hada da:

1. Methyl Slellulose (MC):

   • Yana da narkewa a cikin ruwan sanyi da kuma siffofin m, viscous mafita. Ana amfani da MC azaman mai kauri, mai tsafta, da kuma Filli tsohon A aikace iri.
2. Slelluloxyl Slellulose (hec):
   • Ana samun sel pellosehyl ta gabatar da hydroxyl (-OCH2CH2OH) ƙungiyoyi a kan kwayoyin selulose.
   • Ya nuna kyakkyawan riƙewar ruwa da kuma kayan kwalliya, sanya shi dace da amfani a zane-zane, adheres, kayan kwalliya, da magunguna, da magunguna, da magunguna, da magunguna, da magunguna, da magunguna, da magunguna, da magunguna, da magunguna, da magunguna, da magunguna, da magunguna, da magunguna.
3. Hydroxypyl methyl selululose (hpmc):
   • Hydroxypyl methyp selululose ne copolymer na sel methyl sel metyl sel da slolulopropyl pellulopropyl cellulose.
   • Yana ba da ma'auni na kaddarorin kamar su yadda ake amfani da ruwa, kula da kayan gani, da samar da fim. HPMC anyi amfani dashi sosai a cikin gini, da kayayyakin kulawa na mutum.
4. Carboxymose Carboxymethyl (CMC):
   • Carboxymose carboxymethyl ne ta gabatar da rukuni na Carboxymethyl (-OCHACOOH) ƙungiyoyi a kan kwayoyin selulose.
   • Yana da narkewa cikin ruwa da kuma siffofin cututtukan viscous tare da kyakkyawan thickening da kuma daidaita kaddarorin. Ana amfani da CMC a cikin abinci, magunguna, da aikace-aikace masana'antu.
5. Ethyl hydroxyl pellulose (Ehec):
   • Elthyl Hydroxythyl sel ta hanyar gabatar da ethyl da Hydroxyethyl ƙungiyoyi a kan kwayoyin selulose.
   • Yana nuna inganta kashe ruwa, thickening, da rheological kaddarorin da aka kwatanta da HEC. Ana amfani da Ehec a cikin kayan gini da kayayyakin kulawa na mutum.
