I-Hydroxyethyl cellulose (HEC) iyi-ether engeyona ionic cellulose eyenziwe nge-cellulose yezinto ze-polymer yemvelo ngochungechunge lwe-etherification. Kuyimpushana emhlophe engenaphunga, enganambitheki, engenabuthi noma imbudumbudu, engancibilika emanzini abandayo ukuze kwakheke isixazululo se-viscous esisobala, futhi ukuncibilika akuthintwa inani le-pH. Inokuqina, ukubopha, ukuhlakaza, ukufaka i-emulsifying, ukwenza ifilimu, ukumisa okwesikhashana, i-adsorbing, indawo esebenzayo, egcina umswakama kanye nezindawo ezivimbela usawoti. Isetshenziswa kakhulu kupende, ukwakhiwa, izindwangu, amakhemikhali nsuku zonke, iphepha, ukumba uwoyela nezinye izimboni.
Izindawo zokufaka izicelo eziyinhloko
enamathela
Upende osuselwe emanzini uwuketshezi lwe-viscous olwenziwa ngezincibilikisi eziphilayo noma amanzi asekelwe ku-resin, noma uwoyela, noma i-emulsion, kanye nokwengezwa kwezithasiselo ezihambisanayo. Izingubo ezisekelwe emanzini ezisebenza kahle kakhulu kufanele futhi zibe nokusebenza okuhle kakhulu, amandla amahle okufihla, ukunamathela okuqinile kokunamathela, nokusebenza kahle kokugcinwa kwamanzi; i-cellulose ether iyimpahla eluhlaza efaneleke kakhulu ukuhlinzeka ngalezi zakhiwo.
izakhiwo
Emkhakheni wemboni yezokwakha, i-HEC isetshenziswa njengesengezo ezintweni ezifana nezinto zodonga, ukhonkolo (kuhlanganise ne-asphalt), amathayili anamathiselwe nezinto zokukhahlela.
Izithasiselo zingakhuphula i-viscosity nokujiya kwezinto zokwakha, zithuthukise ukunamathela, ukuthambisa, nokugcinwa kwamanzi, zithuthukise amandla okuguquguquka ezingxenyeni noma izingxenye, zithuthukise ukushwabana, futhi zigweme imifantu emaphethelweni.
Indwangu
Ukotini owenziwe nge-HEC, ama-synthetic fibers noma ama-blends athuthukisa izakhiwo zawo ezinjengokumelana ne-abrasion, ukudaya, ukumelana nomlilo nokumelana namabala, kanye nokuthuthukisa ukuzinza kwemizimba yabo (ukuncipha) nokuqina, ikakhulukazi imicu yokwenziwa, okuyenza iphefumule futhi inciphise i-static. ugesi.
amakhemikhali nsuku zonke
I-Cellulose ether iyisengezo esibalulekile emikhiqizweni yansuku zonke yamakhemikhali. Akukwazi nje ukuthuthukisa i-viscosity yezimonyo ze-liquid noma i-emulsion, kodwa futhi ithuthukise ukuhlakazeka nokuzinza kwegwebu.
ukwenza iphepha
Emkhakheni wokwenza iphepha, i-HEC ingasetshenziswa njenge-ejenti yokulinganisa, i-ejenti eqinisayo kanye nesilungisi sephepha.
ukumba amafutha
I-HEC isetshenziswa kakhulu njenge-ejenti yokuqina neyokuzinzisa enqubweni yokwelashwa kwendawo kawoyela. Kuyikhemikhali enhle yase-oilfield. Yayisetshenziswa kakhulu ekubholeni, ekuqedeleni kahle, ekufakeni usimende nokunye ukukhiqiza uwoyela emazweni angaphandle ngeminyaka yawo-1960.
Eminye imikhakha yesicelo
ezolimo
IHydroxyethyl cellulose (HEC) ingamisa ngempumelelo ubuthi obuqinile kuzifutho ezisekelwe emanzini.
I-HEC ingadlala indima yokunamathela ubuthi emaqabunga emisebenzini yokufafaza; I-HEC ingasetshenziswa njenge-thiener ye-emulsion yesifutho ukuze kuncishiswe ukukhukhuleka kwezidakamizwa, ngaleyo ndlela kwandise umphumela wokusetshenziswa kokufuthwa kwe-foliar.
I-HEC ingasetshenziswa futhi njenge-ejenti eyenza ifilimu kuma-ejenti okugcoba imbewu; njengento enamathelayo ekugayweni kabusha kwamahlamvu kagwayi.
umlilo
I-Hydroxyethyl cellulose ingasetshenziswa njengesengezo sokwandisa ukusebenza kwesembozo sezinto ezingashi, futhi isetshenziswe kabanzi ekulungiseni “izikhukhula” ezingashi.
ukuqamba
IHydroxyethylcellulose ingathuthukisa amandla amanzi kanye nokuncipha kwesihlabathi sikasimende nezinhlelo zesihlabathi se-sodium silicate.
I-microscope
I-Hydroxyethyl cellulose ingasetshenziswa ekukhiqizeni amafilimu nanjenge-disperant ekukhiqizeni amaslayidi amancane.
I-Thickener kuketshezi olugcwele usawoti omningi olusetshenziselwa ukucubungula ifilimu.
upende we-fluorescent tube
Isetshenziswa njenge-binder kanye ne-disperant ezinzile yama-agent we-fluorescent kumashubhu e-fluorescent.
I-Electroplating kanye ne-Electrolysis
Ingavikela i-colloid ethonyeni lokuhlushwa kwe-electrolyte; I-hydroxyethyl cellulose ingakhuthaza ukufakwa okufanayo kusixazululo se-cadmium plating.
izitsha zobumba
Ingasetshenziselwa ukwenza izibophezelo zamandla aphezulu ezitsheni zobumba.
ikhebula
Izinto ezixosha amanzi zivimbela umswakama ukuthi ungangeni ezintamboni ezilimele.
