Insipho ewuketshezi iyisithako sokuhlanza esisebenziseka ngezindlela eziningi futhi esisetshenziswa kabanzi esibaluleke kakhulu ngenxa yokulula nokusebenza kwayo. Kodwa-ke, kwezinye izimo, abasebenzisi bangadinga ukuqina okujiyile ukuze kuthuthukiswe ukusebenza kanye nokusetshenziswa. I-Hydroxyethylcellulose (HEC) iyisithako esidumile sokuqina esisetshenziselwa ukufeza i-viscosity efiselekayo ekwakhiweni kwensipho ewuketshezi.
Funda nge-Hydroxyethyl Cellulose (HEC):
Isakhiwo samakhemikhali kanye nezakhiwo:
I-HEC iyi-polymer encibilika emanzini etholakala ku-cellulose, i-polymer yemvelo etholakala ezindongeni zamaseli ezitshalo.
Isakhiwo sayo samakhemikhali sihlanganisa umgogodla we-cellulose onamaqembu e-hydroxyethyl, okwenza incibilike kakhulu emanzini futhi ihambisane nezinhlobo ezahlukene zezakhi.
Indlela yokwenza ukuqina:
I-HEC iqinisa uketshezi ngokwandisa i-viscosity ngokusebenzisa izakhiwo zokugcina amanzi kanye nokwakha ifilimu.
Yakha inethiwekhi enezinhlangothi ezintathu emanzini, yakha isakhiwo esifana nejeli esithuthukisa ukuhambisana koketshezi.
Ukuhambisana nama-surfactants:
I-HEC ihambisana kahle nama-surfactants avame ukusetshenziswa ekwakhiweni kwensipho ewuketshezi.
Ukuqina kwayo lapho kukhona amakhemikhali ahlukene kwenza kube kuhle kakhulu ekwenzeni imikhiqizo yensipho ibe nkulu.
Izici ezithinta ukuqina kwensipho:
Iresiphi yesepha:
Kubalulekile ukuqonda izithako eziyisisekelo zensipho ewuketshezi. Ukuba khona kwama-ion athile, i-pH, nezinye izingxenye kungathinta ukusebenza kwe-HEC.
Ukujiya okudingekayo:
I-viscosity echazwe ngokucacile ibalulekile ekunqumeni ukuhlushwa okufanele kwe-HEC okufanele isetshenziswe.
izinga lokushisa:
Izinga lokushisa ngesikhathi sokwakheka lithinta ukuncibilika nokusebenza kwe-HEC. Kungadinga ukulungiswa ngokusekelwe ekushiseni kokusebenza.
Ukufaka i-HEC ezindleleni zokupheka insipho ewuketshezi:
Izinto zokwakha kanye nemishini:
Qoqa izithako ezidingekayo kufaka phakathi isisekelo sensipho ewuketshezi, impuphu ye-HEC, amanzi, nanoma yiziphi ezinye izithasiselo.
Ifakwe isitsha sokuxuba, i-stirrer kanye ne-pH meter.
Ukulungiswa kwesisombululo se-HEC:
Kala inani elidingekayo lempuphu ye-HEC ngokusekelwe ku-viscosity oyifunayo.
Faka kancane i-HEC emanzini afudumele, uvuselela njalo ukuvimbela ukuqunjelwa.
Vumela ingxube ukuthi imanzi futhi ivuvuke.
Hlanganisa isisombululo se-HEC nesisekelo sensipho ewuketshezi:
Faka kancane kancane isixazululo se-HEC esisekelweni sensipho ewuketshezi ngenkathi uvuselela kancane.
Qiniseka ukuthi usabalala ngokulinganayo ukuze ugweme ukuqhekeka nokungahambisani.
Gada ukujiya bese ulungisa njengoba kudingeka.
ukulungiswa kwe-pH:
Linganisa i-pH yengxube bese ulungisa uma kudingeka usebenzisa i-citric acid noma i-sodium hydroxide.
Ukugcina ububanzi be-pH obufanele kubalulekile ekuzinzeni kwefomula.
Hlola futhi ulungiselele:
Ukuhlolwa kwe-viscosity kwenziwe ezigabeni ezahlukene ukuze kuthuthukiswe ukuhlushwa kwe-HEC.
Lungisa iresiphi ngokusekelwe emiphumeleni yokuhlolwa kuze kube yilapho kufinyelelwa ukuvumelana okufiselekayo.
Izinto okufanele uzicabangele ngokuqina nokugcina:
Uhlelo lokulwa nokugqwala:
Faka uhlelo lokulondoloza olufanele ukuvimbela ukungcoliswa kwamagciwane futhi wandise isikhathi sokuphila kwensipho ewuketshezi ejiyile.
Iphakheji:
Khetha izinto zokupakisha ezifanele ezingeke zithinte insipho ewuketshezi noma ziphazamise ukuzinza kwe-HEC.
Izimo zokugcina:
Gcina insipho ewuketshezi ejiyile endaweni epholile, eyomile kude nokukhanya kwelanga okuqondile ukuze ihlale iqinile futhi isezingeni layo isikhathi eside.
I-Hydroxyethylcellulose iyisithako esiwusizo esihlinzeka ngesisombululo sokufeza i-viscosity efiselekayo ekwakhiweni kwensipho ewuketshezi. Ngokuqonda izakhiwo zayo, izici ezithinta ukuqina, kanye nenqubo yokufaka isinyathelo ngesinyathelo, abenzi be-formula bangakha insipho ewuketshezi esezingeni eliphezulu enokuhambisana nokusebenza okukhulu. Ukuhlola, ukuhlola kanye nokwenza ngcono kuyizinto ezibalulekile zenqubo, ukuqinisekisa ukuthi umkhiqizo wokugcina uhlangabezana nezidingo ezisebenzayo nezobuhle. Ngokucabangela ngokucophelela izithako kanye namasu okwakha, abakhiqizi bensipho ewuketshezi banganikeza abathengi umkhiqizo osezingeni eliphezulu nojabulisayo.
