Izithasiselo zikasimende i-hydroxyethyl cellulose

IHydroxyethyl cellulose (HEC) i-cellulose ether evame ukusetshenziswa njengesengezo sikasimende embonini yezokwakha.Kuyi-polymer encibilika emanzini etholakala ku-cellulose yemvelo futhi yalungiswa ngenqubo yamakhemikhali ukuze ithuthukise izici zayo zokusebenza.

I-HEC ivame ukusetshenziswa ezintweni ezisekelwe kusimende ukuthuthukisa ukusebenza kwazo, amandla, nokuqina.Kulesi sihloko, sizoxoxa ngezinzuzo ezihlukahlukene zokusebenzisa i-HEC njengesengezo sikasimende nokuthi ingathuthukisa kanjani izakhiwo zezinto ezisekelwe kusimende.

Ukuthuthukiswa Kokusebenza Enye yezinzuzo eziyinhloko zokusebenzisa i-HEC njengesithako sikasimende ukuthi ingathuthukisa ukusebenza kwezinto ezisekelwe kusimende.I-HEC ingenza njenge-thickener kanye ne-rheology modifier, engasiza ekunciphiseni i-viscosity yengxube ye-samente futhi ithuthukise izakhiwo zayo zokugeleza.

Uma i-HEC yengezwa ezintweni ezisekelwe kusimende, ingathuthukisa ukusabalala kwengxube futhi yenze kube lula ukuyisebenzisa.Lokhu kungasiza ekunciphiseni inani lamanzi adingekayo ukuze kuzuzwe ukuvumelana okufunayo, okungathuthukisa amandla onke nokuqina kukasimende.

Ukugcina Amanzi Enye inzuzo yokusebenzisa i-HEC njengesithako sikasimende ukuthi ingathuthukisa izici zokugcinwa kwamanzi zezinto ezisekelwe kusimende.I-HEC ingasebenza njengefilimu-yangaphambili, engasiza ekudaleni umgoqo ovimbela amanzi ukuthi ahwamuke ngokushesha kakhulu engxubeni.

Lokhu kungasiza ekwenzeni ngcono inqubo yokwelapha usimende futhi kuqinisekiswe ukuthi ifinyelela amandla ayo aphelele.Ukwengeza, ukugcinwa kwamanzi okuthuthukisiwe nakho kungasiza ekunciphiseni ingozi yokuqhekeka kanye nokuncipha kwezinto ezisekelwe kusimende, ezingathuthukisa ukuqina kwazo zonke kanye nokuphila isikhathi eside.

I-Adhesion Ethuthukisiwe ye-HEC nayo ingathuthukisa izakhiwo zokunamathela zezinto ezisekelwe kusimende.Uma i-HEC yengezwe kumxube, ingasiza ekwakheni isakhiwo esihlangene futhi esizinzile esingaba nesibopho ngokuphumelelayo nendawo esetshenziswa kuyo.

Lokhu kungathuthukisa amandla onke kanye nokuqina kwento esekwe kusimende futhi kunciphise ingcuphe yokuhlukaniswa noma ukuhlukaniswa ngokuhamba kwesikhathi.Ukunamathela okuthuthukisiwe nakho kungasiza ekunciphiseni inani lokugcinwa nokulungiswa okudingekayo ezintweni ezisekelwe kusimende, okungaba inzuzo enkulu yokonga izindleko embonini yezokwakha.

Ukukhula Ukuqina Ngokuthuthukisa ukusebenza, ukugcinwa kwamanzi, kanye nezakhiwo zokunamathela zezinto ezisekelwe kusimende, i-HEC ingasiza ekwandiseni ukuqina kwazo kukonke.Izinto ezisekelwe kusimende ezithuthukisiwe nge-HEC zingaba nempilo ende yesevisi futhi zidinga ukulungiswa nokulungiswa okuncane ngokuhamba kwesikhathi.

Ngaphezu kwalokho, i-HEC ingaphinde ithuthukise ukumelana kwezinto ezisekelwe kusimende ezicini ezihlukahlukene zemvelo, njengesimo sezulu, imijikelezo yokuncibilika kweqhwa, nokuchayeka kwamakhemikhali.Lokhu kungazenza zilungele ukusetshenziswa ezindaweni ezinokhahlo futhi kuthuthukise ukusebenza kwazo kukonke nokuphila isikhathi eside.

Isiphetho I-HEC iyisengezo sikasimende esisebenza ngezindlela eziningi nesisebenzayo esingathuthukisa izici zokusebenza zezinto ezisekelwe kusimende.Ikhono layo lokuthuthukisa ukusebenza, ukugcinwa kwamanzi, ukunamathela, nokuqina kuyenza ibe ithuluzi elibalulekile embonini yezokwakha.

Uma unentshisekelo yokusebenzisa i-HEC njengesithako sikasimende, kubalulekile ukusebenzisana nomphakeli ohlonishwayo ukuze uqinisekise ukuthi uthola umkhiqizo wekhwalithi ephezulu ohlangabezana nezidingo zakho ezithile kanye nezidingo zakho.I-Kima Chemical ingumkhiqizi kanye nomphakeli wemikhiqizo ye-cellulose ether, okuhlanganisa i-HEC, futhi inikeza uhla lwamabanga kanye nokucaciswa ukuze kuhlangatshezwane nezidingo ezihlukahlukene zemboni yezokwakha.
