Sunadarai na selobase Ethers

Metocel™ alama ce ta ELEPLUSE da ke samarwa da Dow. Wadannan selulose ne aka samo daga cellulose, polymer na halitta da aka samo a jikin bangon tantanin halitta. Chemistry na Methocel ™ ya ƙunshi gyara sel ta hanyar halayen eartharawa. Manyan nau'ikan methocel ™ sun hada da hydroxypropyl methylcellulose (hpmc) da methylcellulose (MC), kowannensu tare da takamaiman halayen sunadarai. Anan ga Janar Overview na Chemistry na Methocel ™:

1. Hydroxypoyl methylcellulhin (hpmc):

• Tsarin:
  • HPMC shine ruwa mai narkewa mai ruwa mai narkewa tare da maɓalli guda biyu: Hydroxypropyl (HP) da Methyl (m) rukuni.
  • Groupsungiyoyin Hydroxypyl sun gabatar da aikin hydrophili na hydrophilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihilihili.
  • Kungiyoyin metyl sun ba da gudummawa ga karyayyar gaba ɗaya kuma su rinjayi kaddarorin polymer.
• Dauki extoration:
  • Ana samar da HPMC ta hanyar gaggafa tare da propylelene oxide (don hydroxypropyl ƙungiyoyi) da methyl chloride (don methyl ƙungiyoyi).
  • Halin da aka yi a hankali ana sarrafa shi a hankali don cimma yanayin da ake so (DS) don ƙungiyoyin hydroxypyl da metyl.
• Kaddarorin:
  • HPMC ta nuna kyakkyawan abinci na ruwa, kaddarorin fim, kuma yana iya samar da saki mai sarrafawa a aikace-aikace na magunguna.
  • Matsayi na Canji yana tasiri ga danko na polymer, riƙewar ruwa, da sauran kaddarorin.

2. Ethylcellulose (MC):

• Tsarin:
  • MC sel ne ether ether tare da methyl sumaents.
  • Ya yi kama da HPMC amma ba su da wasu ƙungiyoyin hydroxypyl.
• Dauki extoration:
  • An fitar da MC ta hanyar Entarlulose tare da Methyl Chloride.
  • An sarrafa yanayin amsawa don cimma nasarar da ake so na canzawa.
• Kaddarorin:
  • MC ruwa mai narkewa ne kuma yana da aikace-aikace a cikin magunguna, gini, da masana'antar abinci.
  • Ana amfani dashi azaman ɗan akuya, thickenerner, da kuma tsayayye.

3. Kaddarorin gama gari:

• Sanarwar ruwa: duka HPMC da MC suna narkewa a cikin ruwan sanyi, suna tabbatar da ƙarin mafita.
• Tsarin fim: suna iya samar da fina-finai masu sassauƙa da cheesive fina-finai, yana yin su da amfani a aikace-aikace iri-iri.
• Thickening: Metocel ™ PLELUOSE ELES DUBI KYAU TAFIYA TAFIYA TAFIYA TAFIYA.

4. Aikace-aikace:

• Magana: Amfani da shi a cikin mayafin kwamfutar hannu, ɗaure, da tsara saki.
• Gina: aiki a cikin harsuna, tile adheres, da sauran kayan gini.
• Abinci: Amfani da shi azaman ƙiyayya da masu riƙe kayayyaki a cikin kayayyakin abinci.
• Kulawa na sirri: An samo shi a cikin kayan kwalliya, shamfu, da sauran abubuwan kulawa na sirri.

Chemistry na plloose elethers ELERS sa sa su kwayoyi masu yawa tare da kewayon aikace-aikace, yin riƙewar ruwa, da sauran halaye na ruwa, da sauran halaye na ruwa. Za'a iya dacewa da takamaiman kaddarorin ta daidaita mataki na musanya da sauran sigogi masu kerawa.
