Inani eliphansi le-hec hydroxyethyl cellulose

IHydroxyethyl cellulose (HEC) iyi-polymer eguquguqukayo esetshenziswa kabanzi ezimbonini ezahlukahlukene, kufaka phakathi okokugqoka, okokunamathisela, imikhiqizo yokunakekelwa komuntu siqu, kanye nemithi. Njengoba isidingo se-HEC sikhula kulezi zimboni, abakhiqizi bafuna izindlela zokunikeza ezinye izindlela ezinamanani aphansi ukuze bahlangabezane nezidingo zemakethe. Kulesi sihloko, sizoxoxa ngezinye zezindlela abakhiqizi abanganikeza ngazo imikhiqizo ye-HEC enenani eliphansi.

Enye yezindlela zokunikeza i-HEC enamanani aphansi ukuyikhiqiza kusetshenziswa izinto zokusetshenziswa ezishibhile. I-HEC isuselwa ku-cellulose, evame ukutholakala ku-pulp yezinkuni, ama-linters kakotini, noma eminye imithombo yezitshalo. Kodwa-ke, izindleko ze-cellulose zingahluka kuye ngokuthi umthombo kanye nekhwalithi. Abakhiqizi bangasebenzisa i-cellulose yezinga eliphansi noma esenziwe kabusha ukuze bakhiqize i-HEC, engasiza ukunciphisa izindleko zokukhiqiza.

Enye indlela yokunikeza i-HEC enenani eliphansi ukuthuthukisa inqubo yokukhiqiza. I-HEC ivame ukukhiqizwa ngokusabela kwe-cellulose nge-ethylene oxide, kulandelwa i-etherification nge-monochloroacetic acid noma amanye amakhemikhali. Inqubo yokukhiqiza ingathuthukiswa ngokusebenzisa izimo zokusabela ezisebenza kahle kakhulu, njengamazinga okushisa aphezulu noma izingcindezi, noma ngokusebenzisa ama-catalyst okusabela ahlukene. Ukuthuthukisa inqubo yokukhiqiza kunganciphisa izindleko zokukhiqiza futhi kuholele emikhiqizweni ye-HEC enenani eliphansi.

Indlela yesithathu yokunikeza i-HEC enenani eliphansi ukugxila ekukhiqizeni i-HEC ngamamaki aphansi e-viscosity. I-HEC itholakala kumabanga ahlukahlukene we-viscosity, kusukela kokuphansi kuye phezulu. Amabanga aphezulu e-viscosity ngokuvamile anezindawo zokujiya ezingcono futhi ayabiza kakhulu. Ngokukhiqiza amabanga aphansi e-viscosity e-HEC, abakhiqizi banganikela ngemikhiqizo enenani eliphansi esahlangabezana nezidingo zemakethe.

Ekugcineni, abakhiqizi banganikeza i-HEC enenani eliphansi ngokugxila ezindleleni zokukhiqiza ezingabizi kakhulu. Isibonelo, abanye abakhiqizi baye bahlakulela izinqubo ezintsha zokukhiqiza ezisebenzisa amandla amancane noma amakhemikhali ambalwa, okuholela ekunciphiseni izindleko zokukhiqiza. Abanye abakhiqizi bangagxila ekwandiseni uchungechunge lwabo lokuhlinzeka noma inethiwekhi yokusabalalisa ukuze banciphise izindleko zokuhamba nezokugcina.

Uma ufuna imikhiqizo ye-HEC enenani eliphansi, abathengi kufanele baqaphele ukuhwebelana kwekhwalithi okungaba khona. Imikhiqizo enenani eliphansi le-HEC ingase ibe nokuhlanzeka okuphansi, i-viscosity ephansi, noma ezinye izinkinga zekhwalithi ezingathinta ukusebenza kwayo ezinhlelweni ezihlukahlukene. Abathengi kufanele futhi baqaphele imikhiqizo enenani eliphansi kakhulu kunesilinganiso semakethe, njengoba ingase ibe eyekhwalithi ephansi noma evela emithonjeni engathembekile.

Kafushane, abakhiqizi banganikela ngemikhiqizo ye-HEC enenani eliphansi ngokusebenzisa izinto ezingavuthiwe ezishibhile, bathuthukise inqubo yokukhiqiza, bagxile kumabanga aphansi e-viscosity, nokusebenzisa izindlela zokukhiqiza ezibizayo. Kodwa-ke, abathengi kufanele baqaphele ukuhwebelana kwekhwalithi okungaba khona futhi kufanele bakhethe imikhiqizo ehlangabezana nezidingo zabo ezithile kanye nezidingo zekhwalithi.
