Iselulosi, i-hydroxyethyl ether (MW 1000000)

Iselulosi hydroxyethyl etheriphuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeseli zezityalo. Ukuguqulwa kwe-ether ye-hydroxyethyl kubandakanya ukwazisa amaqela e-hydroxyethyl kwisakhiwo se-cellulose. Ubunzima bemolekyuli (MW) obucaciswe njenge-1,000,000 ekunokwenzeka ukuba bubhekiselele kumndilili wobunzima bemolekyuli ye-cellulose hydroxyethyl ether. Nanga amanye amanqaku aphambili malunga ne-cellulose hydroxyethyl ether enobunzima bemolekyuli obuyi-1,000,000:

1. Ulwakhiwo lweMichiza:
   • I-Cellulose hydroxyethyl ether ithathwa kwi-cellulose ngokuyiphendula nge-ethylene oxide, okubangela ukuqaliswa kwamaqela e-hydroxyethyl kwi-backbone ye-cellulose.
2. Ubunzima beMolekyuli:
   • Ubunzima bemolekyuli be-1,000,000 bubonisa umlinganiselo wobunzima bemolekyuli ye-cellulose hydroxyethyl ether. Eli xabiso ngumlinganiselo we-avareji yobunzima be-polymer chain kwisampulu.
3. Iinkcazelo Ngeempawu:
   • Iimpawu ezithile zomzimba ze-cellulose hydroxyethyl ether, ezifana nokunyibilika, i-viscosity, kunye nezakhono zokwenza ijeli, zixhomekeke kwizinto ezifana neqondo lokuthatha indawo (DS) kunye nobunzima bemolekyuli. Ubunzima beemolekyuli eziphakamileyo zinokuphembelela i-viscosity kunye nokuziphatha kwe-rheological yezisombululo.
4. Ukunyibilika:
   • I-cellulose hydroxyethyl ether iqhele ukunyibilika emanzini. Iqondo lokutshintshwa kunye nobunzima be-molecular bunokuchaphazela ukunyibilika kwayo kunye nokugxininiswa apho yenza izisombululo ezicacileyo.
5. Usetyenziso:
   • I-Cellulose hydroxyethyl ether enobunzima bemolekyuli ye-1,000,000 inokufumana usetyenziso kumashishini ahlukeneyo:
     • Pharmaceuticals: Isenokusetyenziswa kwimixube elawulwa-ukukhutshwa kweyeza, i-tablet coatings, kunye nezinye izicelo zoxubo.
     • Izinto zokwakha: Kudaka, udaka, kunye nokuncamatheliswa kweethayile ukuphucula ukugcinwa kwamanzi kunye nokusebenza.
     • Iingubo kunye neeFilimu: Kwimveliso yeengubo kunye neefilimu kwiimpawu zayo zokwenza ifilimu.
     • IiMveliso zokuKhathalela umntu: Kwizinto zokuthambisa kunye nezinto zokhathalelo lomntu ngenxa yokuqina kwayo kunye nokuzinzisa iipropathi.
6. Ulawulo lweRheological:
   • Ukongezwa kwe-cellulose hydroxyethyl ether kunokubonelela ngokulawula iipropati ze-rheological zezisombululo, okwenza kube luncedo ekuqulunqweni apho ukulawulwa kwe-viscosity kubalulekile.
7. Ukonakala kwezinto eziphilayo:
   • I-cellulose ethers, kuqukwa ne-hydroxyethyl ether derivatives, zidla ngokubola, zinegalelo kwiprofayile yazo ehambelana nokusingqongileyo.
8. Udibaniso:
   • I-synthesis ibandakanya ukuphendula kwe-cellulose kunye ne-ethylene oxide phambi kwe-alkali. Iqondo lokutshintshwa kunye nobunzima bemolekyuli bunokulawulwa ngexesha lenkqubo yokudibanisa.
9. Uphando nophuhliso:
   • Abaphandi kunye nabaqulunqi banokukhetha i-cellulose ethile ye-hydroxyethyl ethers ngokusekelwe kubunzima be-molecular kunye neqondo lokutshintshela ukuphumeza iipropati ezifunwayo kwizicelo ezahlukeneyo.

Kubalulekile ukuba uqaphele ukuba iipropati kunye nokusetyenziswa kwe-cellulose hydroxyethyl ether inokuhluka ngokusekelwe kwiimpawu zayo ezithile, kwaye ulwazi olukhankanyiweyo lubonelela ngokubanzi. Iinkcukacha zobugcisa ezinikwe ngabavelisi okanye ababoneleli zibalulekile ekuqondeni imveliso ethile ye-cellulose hydroxyethyl ether ekuthethwa ngayo.
