Ukusetshenziswa kwe-Hydroxyethyl Cellulose (HEC)

I-Hydroxyethyl cellulose (HEC)i-non-ionic cellulose ether eyenziwe nge-cellulose ye-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. Kusetshenziswa kakhulu upende, ukwakhiwa, izindwangu, amakhemikhali nsuku zonke, iphepha, ukugaya uwoyela kanye nezinye izimboni.

Izindawo ezisetshenziswa kakhulu:

1.Upende: Upende osuselwe emanzini uwuketshezi olubonakalayo olwakhiwe ngezincibilikizi 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.

2.Ukwakhiwa: Emkhakheni wemboni yezokwakha, i-HEC isetshenziswa njengesengezo sezinto ezifana nodonga, ukhonkolo (kuhlanganise ne-asphalt), amathayili anamathisiwe nezinto zokukhahlela, ezingakhuphula i-viscosity kanye nokujiya kwezinto zokwakha, ukuthuthukisa ukunamathela, ukuthambisa, nokugcinwa kwamanzi. Thuthukisa amandla okugoba ezingxenyeni noma izingxenye, thuthukisa ukushwabana, futhi ugweme imifantu emaphethelweni.

I-3.Indwangu: ukotini olashwe nge-HEC, imicu yokwenziwa noma ama-blends athuthukisa izakhiwo zawo ezinjengokumelana nemihuzuko, ukudaya, ukumelana nomlilo nokumelana namabala, kanye nokuthuthukisa ukuzinza kwemizimba yazo (ukuncipha) nokuqina, ikakhulukazi emicu yokwenziwa, okuyenza iphefumule futhi inciphise ugesi omile.

4.Ikhemikhali yansuku 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.

5.Iphepha: Emkhakheni wokwenza iphepha, i-HEC ingasetshenziswa njenge-ejenti yokulinganisa, i-ejenti eqinisayo kanye nesishintshi sephepha.

6. Ukumba uwoyela: I-HEC isetshenziswa kakhulu njenge-ejenti ejiyayo neqinisayo 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:

I-HECingadlala indima yokunamathela ubuthi emaqabunga emisebenzini yokufafaza; I-HEC ingasetshenziswa njenge-thickener ye-emulsion yesifutho ukunciphisa ukukhukhuleka kwezidakamizwa, ngaleyo ndlela kwandiswe umphumela wokusetshenziswa kokufuthwa kwe-foliar. I-HEC ingasetshenziswa futhi njenge-ejenti eyenza ifilimu kuma-ejenti okugcoba imbewu; njengesibopho ekugayweni kabusha kwamaqabunga kagwayi. I-Hydroxyethyl cellulose ingasetshenziswa njengesengezo ukuze kwandiswe ukusebenza kwesembozo sezinto ezingashi, futhi iye yasetshenziswa kabanzi ekulungiseleleni "izikhukhula" ezingashi. I-Hydroxyethyl cellulose ingathuthukisa amandla amanzi kanye nokuncipha kwesihlabathi sikasimende nezinhlelo zesihlabathi se-sodium silicate. I-Hydroxyethyl cellulose ingasetshenziswa ekukhiqizeni amafilimu nanjenge-disperant ekukhiqizeni amaslayidi amancane. I-Thickener kuketshezi olunosawoti omningi osetshenziswa ekucubunguleni ifilimu. Isetshenziswa njenge-binder kanye ne-disperant ezinzile yama-agent we-fluorescent kumashubhu e-fluorescent. Ingavikela i-colloid ethonyeni lokuhlushwa kwe-electrolyte; I-hydroxyethyl cellulose ingakhuthaza ukufakwa okufanayo kusixazululo se-cadmium plating. Ingasetshenziselwa ukwenza izibophezelo zamandla aphezulu ezitsheni zobumba. Izinto ezixosha amanzi zivimbela umswakama ukuthi ungangeni ezintamboni ezilimele.
