Isepha yolwelo yinto eguquguqukayo kwaye isetyenziswa ngokubanzi kwindawo yokucoca exatyiswe ngokulula kunye nokusebenza kwayo. Nangona kunjalo, kwezinye iimeko, abasebenzisi banokufuna ukuguquguquka okuthe kratya ukuze kuphuculwe ukusebenza kunye nokusetyenziswa. IHydroxyethylcellulose (HEC) sisixhobo sokutyebisa esidumileyo esisetyenziselwa ukufikelela kwi-viscosity efunekayo kukwenziwa kwesepha yolwelo.
Funda ngeHydroxyethyl Cellulose (HEC):
Ubume bekhemikhali kunye neempawu:
I-HEC i-polymer e-soluble yamanzi ephuma kwi-cellulose, i-polymer yendalo efumaneka kwiindonga zeeseli zezityalo.
Ubume bayo beekhemikhali bubandakanya umqolo we-cellulose kunye namaqela e-hydroxyethyl, okwenza ukuba i-soluble kakhulu emanzini kwaye ihambelane neentlobo ezahlukeneyo zokuqulunqa.
Indlela yokutyebisa:
I-HEC ikhulisa ulwelo ngokunyusa i-viscosity ngokugcina amanzi kunye neempawu zokwenza ifilimu.
Yenza inethiwekhi ye-dimensional emithathu emanzini, idala i-gel-efana nesakhiwo esiphucula ukuhambelana kolwelo.
Ukuhambelana nee-surfactants:
I-HEC inokuhambelana kakuhle kunye ne-surfactants edla ngokusetyenziswa kwimixube yesepha engamanzi.
Ukuzinza kwayo phambi kweekhemikhali ezahlukeneyo kuyenza ilungele ukujiya imveliso yesepha.
Izinto ezichaphazela ukujiya kwesepha:
Iresiphi yesepha:
Kubalulekile ukuqonda izithako ezisisiseko zesepha engamanzi. Ubukho bee-ion ezithile, i-pH, kunye namanye amacandelo anokuchaphazela ukusebenza kwe-HEC.
viscosity efunekayo:
I-viscosity ekujoliswe kuyo echazwe ngokucacileyo ibalulekile ekunqumeni ukugxininiswa okufanelekileyo kwe-HEC ukuba isetyenziswe.
ubushushu:
Iqondo lokushisa ngexesha lokuqulunqa lichaphazela ukuchithwa kunye nokusebenza kwe-HEC. Isenokufuna uhlengahlengiso olusekwe kubushushu bokusebenza.
Ukubandakanya i-HEC kwiiresiphi zesepha elulwelo:
Izixhobo kunye nezixhobo:
Qokelela izithako eziyimfuneko kubandakanya isiseko sesepha engamanzi, umgubo weHEC, amanzi, kunye nazo naziphi na ezinye izongezo.
Ixhotyiswe ngesitya sokuxuba, i-stirrer kunye nemitha ye-pH.
Ukulungiswa kwesisombululo se-HEC:
Ukulinganisa umlinganiselo ofunekayo we-HEC powder ngokusekelwe kwi-viscosity oyifunayo.
Yongeza kancinci i-HEC kumanzi afudumeleyo, uvuselela rhoqo ukukhusela i-clumping.
Vumela umxube ukuba umanzi kwaye udumbe.
Dibanisa isisombululo se-HEC kunye nesiseko sesepha engamanzi:
Kancinci wongeza isisombululo se-HEC kwisiseko sesepha engamanzi ngelixa uvuselela ngobumnene.
Qinisekisa ukuba usasaza ngokulinganayo ukuphepha i-clumps kunye nokungahambelani.
Beka iliso kwi-viscosity kwaye uhlengahlengise njengoko kufuneka.
Uhlengahlengiso lwe-pH:
Ukulinganisa i-pH yomxube kwaye ulungelelanise ukuba kuyimfuneko usebenzisa i-citric acid okanye i-sodium hydroxide.
Ukugcina uluhlu lwe-pH olufanelekileyo lubalulekile ekuzinzeni kokuqulunqwa.
Vavanya kwaye ulungiselele:
Iimvavanyo ze-Viscosity zenziwa kwizigaba ezahlukeneyo zokwandisa ukuxininisa kwe-HEC.
Lungisa iresiphi esekelwe kwiziphumo zovavanyo de kube ukuhambelana okufunwayo kufezekiswe.
Uzinzo nogcino ingqwalasela:
Inkqubo yokunqanda ukubola:
Dibanisa isixokelelwano esifanelekileyo sokuthintela ukungcoliseka kweentsholongwane kunye nokwandisa ixesha leshelufu yesepha yolwelo ejiyileyo.
Umqulu:
Khetha izinto ezifanelekileyo zokupakisha ezingayi kusabela ngesepha engamanzi okanye zibeke esichengeni uzinzo lweHEC.
Iimeko zokugcina:
Gcina isepha elulwelo ejiyileyo kwindawo epholileyo, eyomileyo, kude nelanga elithe ngqo ukugcina uzinzo kunye nomgangatho wayo kwixesha elide.
IHydroxyethylcellulose sisityebi esixabisekileyo esibonelela ngesisombululo sokufezekisa i-viscosity efunwayo kwimiqulu yesepha engamanzi. Ngokuqonda iipropathi zayo, izinto ezichaphazela ukutyeba, kunye nenkqubo yokufakwa kwamanyathelo ngamanyathelo, abaqulunqi banokwenza iisepha zolwelo ezikumgangatho ophezulu kunye nokuhambelana okukhulu kunye nokusebenza. Uvavanyo, uvavanyo kunye nokuphucula yimiba ephambili yenkqubo, ukuqinisekisa ukuba imveliso yokugqibela ihlangabezana neemfuno zokusebenza kunye nobuhle. Ngokuqwalasela ngokucophelela izithako kunye nobuchule bokuqulunqa, abavelisi besepha yolwelo banokubonelela abathengi ngemveliso ephezulu kunye neyonwabileyo.
