Iipropathi ze-hydroxyythl seluplose

I-HydroxyEtheetheetheetheetheetheetheethl seluplose (hec) yi-polymer eqhelekileyo ye-noinic isetyenziswe ngokubanzi kwiindawo ezahlukeneyo zeshishini. Iveliswa ikakhulu ngokuphendula kweekhemikhali ezifana ne-alkalization kunye nokhenketho lwe-ether Ineepropathi ezongeziweyo zomzimba kunye neekhemikhali, zenza ukuba zibe yinto engenakuphikwa kwizicelo ezininzi.

I-1. Ubume kunye nobunzima bemolekyuli
Iyunithi esisiseko ye-hydroxyythl seluplose yi-sellese chain equlwe iimolekyuli zeglucose. Kwindawo ethile ye-hydroxyl ye-HYDROXYL ye-molecular thein, i-hydroxyytethl (-Ch2C2C2oh) ingeniswa ngamaqela aziswanga ngokuphendula. Ngenxa yokungenisa la maqela, i-HydroxyEtheetheethl Selelose i-hydrophilic ngakumbi kwaye inesifo sokungathathi ntweni kunokuba selusu. Ngokweemfuno ezahlukeneyo zesicelo, inqanaba lokufakwa endaweni (DS) kunye ne-molar Ngokubanzi, uluhlu lwesisindo se-HEC lubanzi, luvela kumashumi amawaka kwizigidi ze-daltons, eyenza ibonise iipropathi ezahlukeneyo zeRheeology kwisisombululo semifanekiso.

2. Ukungasebenzi kwamanzi kunye nokungapheli
Ngenxa yepropathi yayo engeyiyo i-ionic, i-hydroxythyl seluplose inokunyibilika kuwo omabini amabanda kwaye ashushu ukwenza isisombululo se-viscous esibonakalayo. Ireyithi yayo yokuchithwa ixhomekeke kubunzima bemolekyuli, isidanga sokufaka kunye neqondo lobushushu lamanzi. Iindidi zemolekyuli eziphakamileyo ze-HOC zinyibilikisa kancinci kodwa zenza iZisombululo ze-vicous ziyinto ephantsi, ngelixa iintlobo zemolekyuli eziphantsi zemolekyuli zinyibilikisa ngokulula kodwa zivelisa i-viscofies ephantsi. Ngenxa yobume besisombululo sayo, i-HEC inonyamezelo olufanelekileyo kwiinguqu ze-pH kunye nee-electrolytes kwaye zinokugcina imeko yaso echithwe kunye nokuzinza kwi-PH ye-PH ye-PH (2-12).

I-3. Iipropathi ze-ticeke
Enye yezona ndawo zibalulekileyo zeheks kukukwazi kwayo. Ukugxininisa okuphantsi (i-0.5% -2%), izisombululo ze-HEC zinokubonisa iziphumo ezikhulu kwaye zibonise iimpawu ze-pseudoplastic, oktliseka i-Shear yokuziphatha, i-viscosity yesisombululo ihla, i-eulsions. Ukongeza, i-hec inokusebenza ngokuhamba kwamanye amazwe kunye nezinye iziqwengana ezifana ne-carboxymethyl selulose (CMC) kunye ne-guntan gum ukuya phambili.

4. Uzinzo kunye nokuhambelana
I-HEC inozinzo oluhle lweekhemikhali kwaye ayihambelani ekuthandeni okanye kutshintsho lweekhemikhali phantsi kweemeko ezininzi. Isisombululo sayo sinokuvumela ukugxila ngaphezulu kwee-electrongs kunye noluhlu lwe-hle, oluzinzileyo kwiindawo ezahlukeneyo. Ukongeza, i-HEC ikwahambelana nezinye iichemicals ezininzi ezinje nge-surfacapes, i-polymers, iityuwa ze-inorganic, njl njl, kunjalo, njalo rhoqo kwiinkqubo zokwenziwa kwezinto ukuze zibonelele ngeziphumo zozinzo kunye neziphumo zokwenza uzinzo.

5. Iindawo zesicelo
Ngenxa yepropathi yayo eyahlukileyo, i-HEC isetyenziswe ngokubanzi kumasimi amaninzi. Oku kulandelayo zizicelo eziqhelekileyo:

Izinto zokwakha: ekwakheni iingubo, iipeyinti, i-podds, njl.

Ukukhutshwa kweoyile: Kwishishini leoyile, i-HEC isetyenziswa kumalungiselelo e-flubleng fluids kunye nokugqitywa kwe-chicker njenge-gickener kunye nelahleko yelahleko yokuphucula i-ratheowiler yokuphucula i-geomology yodaka kwaye ikhusele ukuwa kakuhle.

I-cosmetics kunye neemveliso zononophelo zobuqu: I-HEC isetyenziswa ngokubanzi kwiimveliso zononophelo zobuqu ezifana ne-shampoo, i-jell, i-cream, i-emuls, i-enulsifier, i-enulsifier, i-stutifier kunye ne-stailimize inyanzelise imvume kwaye isebenzise amava emveliso.

Umzi mveliso wamachiza, i-HEC isetyenziswa njengoncedo lokubumba, iarhente yokukhutshwa igcinwe kunye nokumisa iarhente yeetafile ukunceda ukulawula iziyobisi zeziyobisi.

Ishishini lokutya: Nangona lisetyenziswe kwinani elincinci, i-HEC lingasetyenziswa njengesongezo lokutya ukuze sihlengahlengise i-vickosity kunye nencasa yokutya.

I-6. Ukukhusela kwendalo kunye nokhuseleko
I-Hec yindawo ye-selsulose yendalo ekhupha i-biodegradiance elungileyo, ngoko inamachaphaza amancinci kwindalo esingqongileyo emva kokusetyenziswa. Ukongeza, ihec ithathwa njengemichiza ngokukhuselekileyo kwaye isetyenziswa ngokubanzi kwiimveliso ezinxibelelana nomzimba womntu, ezinjengeecosmetics, iziyobisi kunye nokutya. Nangona kunjalo, ngexesha lokuveliswa kwemizi-mveliso kunye nokusetyenziswa, Imigaqo yokhuseleko ehambelana nayo kufuneka ilandelwe ukuthintela ukuphendula okucaphukisayo okunokubangelwa kukuphefumla okanye ukunxibelelana kwexesha elide.

7. Ukugcina kunye nokusebenzisa amanyathelo okhuseleko
I-HydroxyEtheetheetheetheetheetheetheetheetheetheetheetheetheetheethl kufuneka igcinwe kwindawo eyomileyo neyinopholileyo yokuphepha ukufuma kunye ne-AgeGlomeration. Xa usebenzisa, kufuneka kongezwe emanzini kancinci kwaye ngokulinganayo ukuthintela ukwahluka okubangelwa ukongeza isixa esikhulu ngexesha elinye. Kwangelo xesha, kuba kuthatha ixesha elithile lokunyibilikisa, kusoloko kuyimfuneko ukuyishiya ixesha elithile emva kokupheliswa ukuqinisekisa ukuchithwa okugqibeleleyo kunye nokuncamathisa okuzinzileyo.

Ngenxa yokungabinamali kwawo okugqwesileyo, ukuqina, uzinzo kunye nokuhambelana, i-hydroxyEtheetheetheetheetheetheetheetheethl iye yangena kumasimi amaninzi amashishini. Ngokuphuhliswa kwetekhnoloji yetekhnoloji, indawo yokusetyenziswa kwe-hec iya kuqhubeka nokwandisa, ukubonelela ngezisombululo ezingcono kumashishini ahlukeneyo.
