Indima ye-Hydroxye Ethyl Selelose (Hec) kwiChemistry

I-Hydroxye Ethyl Selelose (Hec) sisiseko esininzi kwaye sisebenzise i-polymer esetyenziswa ngokubanzi kwizicelo ezahlukeneyo kwicandelo lekhemicali. I-polymer ye-Slymer ye-Slymer ikwiselselose, kunye ne-seluplose yi-polymer yendalo efumaneka kudonga lweselfowuni. Ukuqaliswa kweqela le-hydroxyl kunokuphucula ukubenzela amanzi kwaye uguqule iipropathi zomzimba kunye neekhemikhali ze-seluplose.

1. Intshayelelo kwi-hydroxye yeyl (hec)

I-Hydroxye I-Ether kukukhupha i-sellyulose, kunye nesellulose ngumgca we-polymer oqulunqwe ngeyunithi ye-glucose exhunyiwe yi-β-1,4-Glycoade Bond. Iqela le-hydroxyl kwi-hec laziswa ngokuphendula nge-oxide. Olu hlengahlengiso luphucula ulwelo lwepolymer emanzini, kwaye luyinika iimpawu zokufumana izicelo kwiinkqubo ezahlukeneyo zekhemikhali.

2. Ulwakhiwo kunye neempawu ze-hec

Ulwakhiwo: Iqela le-hydroxyl liqhotyoshelwe kwiqela le-hydroxyl ye-chain ephambili yeselsulose, enika i-hec engaqhelekanga kwaye engasengqiqweni. Inqanaba lokutshintshwa (i-DS) libonisa inani eliphakathi lamaqela e-hydroxyl yeyunithi nganye ye-glucose nganye kwaye ichaphazela iimpawu zePolymer.

Ukuluka: Hec kunokuyichitha ngokulula emanzini abandayo, ukwenza isisombululo esibonakalayo nesibonisa i-viscous. Iziphumo zokungasebenzi zichaphazelekile zizinto ezinje ngamaqondo obushushu, amandla e-PH.

I-Viskosity: Enye yezinto eziphambili ze-hec kukukwazi kwayo ukuguqula i-viscofity yesisombululo. Oku kwenza ukuba ixabiseke kumashishini alawula ubugqwirha.

3. Synthesis ye-hydroxyl yeyyl seyyl selyulose

Ukuphendula okuxhasayo: I-Synthesis ye-HEC ibandakanya ukuphendula phakathi kwetywina kunye ne-oxide ngokungabikho kwe-alkaline catalysts. Ungalawula inqanaba lokutshintsha endaweni yokuhlengahlengiswa kweemeko zokuphendula (njengamaqondo obushushu, ixesha, kunye nokugxila kwendlela).

4. Isicelo semichiza

Ipeyinti kunye neengubo: hec zisetyenziswa ngokubanzi njengokuthambisa kunye nokuzinza kwipeyinti yepeyinti kunye neengubo. Iphucula iimpawu zesicelo kwaye iphucule ukuhamba kwepeyinti.

Cosmetics and personal care products: Due to its water solution and thickening characteristics, HEC can be found in many cosmetics and personal care recipes, including lotion, shampoo and cream.

Amayeza: Kwifomula yechiza, i-HEC isetyenziswa njengeetafile, ifilimu kunye neendlela zokugcina iitafile, iitafile zemali, iigesi zendawo kunye nokukhutshwa kwendawo yokuhambisa iziyobisi.

Umzi-mveliso wokwakha: I-HEC isetyenziselwa izinto zokwakha, ezinje ngesamente-ebhulukuqa kunye nemikhono yokuphucula ubuchule kunye ne-adhesion.

5. Indima yokuthambisa amanzi

Ifomusi ye-Pubin: Faka i-HEC kwimbeko esekwe emanzini ukubonelela ngeempawu zokunxibelelana, uzinzo nophuculo. Iluncedo ngakumbi kwisicelo esingafanelekanga sababulala abanamakhwenkwe.

6. Ukuphucula ukubuyiswa kweoyile

I-Viscosity Modifier: Kwishishini le-oyile kunye nendalo, i-HEC isetyenziswa njenge-viscofier modifier yokwandisa i-oyile (i-EOR). Iphucula i-viscosity yamanzi asetyenziselwa inaliti, ngaloo ndlela ukuphucula i-oyile kwi-reservoir.

7. Impembelelo yokusingqongileyo kunye nokuZinza

Ukonakaliswa kwe-Bio: Hec kudla ngokujonga njenge-biodegrades kwaye kunceda ukwamkelwa kwendalo esingqongileyo. Nangona kunjalo, uzinzo lupheleleyo lwemveliso lwayo luxhomekeke kwizinto ezinje ngenkqubo yeselselese kunye nenkqubo yokwenza.

8. Umngeni kunye neembono ezizayo

I-Biomiticatible: Nangona i-HC ithathelwa ingqalelo kukhuselekile, i-biomatisi-i-biomatisines kunye neziphumo zempilo ezinokubakho kwizicelo ezithile, ngakumbi kwicandelo lezonyango kunye neziyobisi, zisekhona amasimi ophando.
I-Green Green: Iinzame eziqhubekayo zigxile kuphuhliso lweendlela zeSimo seSimo sendalo esisingqongileyo ukunciphisa ifuthe lendalo kwimveliso.
I-Hydroxyeyl seluplose idlala indima ephambili kwizicelo ezahlukeneyo zekhemikhali, ibonelela ngendibaniselwano eyodwa yamanzi, ukulungiswa kwe-viscosity kunye ne-biodegradition. Impembelelo yayo ichitha amashishini anjengepeyinti, i-cosmetics, amayeza, amayeza kunye nokubuyiswa kweoyile. Ngokuqhubeka kophando, uhlobo lwe-hec kunye nesicelo sayo kumacandelo avelayo sinokwandisa, ngaloo ndlela zibaluleke kakhulu kwintsimi ye chemistry.

I-Hydroxye Ethyl Selelose iqinisekisa iimfuno zePolymer's Polyner's kwintlanganiso yecandelo leekhemikhali, kwaye ifuthe layo liqhubekile nokwandisa kwiindawo ezininzi ezixhomekeke ekufezekiseni izinto ezisemgangathweni.
