Abstrac:
Lilemong tsa morao tjena, liphatlalatso tse thehiloeng metsing li amohetse tlhokomelo ea metsi ka lebaka la botsoalle ba bona ba tikoloho le complic e tlase ea tikoloho le bongata ba vutland. Hydroxethylcelllulosa (Hec) e sebelisetsoa polymer e qhibilihang ea metsi ka mefuta ena, e sebetsang e le bolo ea thipa ho eketsa litšoantšisi le ho laola Rithelogy.
hlahisa:
1.1 semelo:
Likotsi tse thehiloeng metsing li fetohile mokhoa o motle oa tikoloho o tseleng ea setso, o rarollang mathata a amanang le sebopeho sa tikoloho le tikoloho ea tikoloho. Hydroxethylcelllulose (Hec) ke motsoako oa bohlokoa oa ho theha likotsi tsa metsi le botsitso.
Morero oa 1.2:
Sengoliloeng sena se ikemiselitse ho hlaba litšobotsi tsa lillo tse ngata tsa tšepe le ho ithuta tšusumetso ea mabaka a fapaneng linthong tsa eona. Ho utloisisa likarolo tsena ho bohlokoa ho ntlafatsa liforomo tsa koetliso le ho fihlela ts'ebetso e lakatsehang.
Hydroxethylcelldilose (hec):
2.1 sebopeho le ts'ebetso:
Hec ke 'muelli oa thepa ea kuulo o fumanoeng ke karabelo ea menyetla ea celluloulose le Ethylene Oxide. Kenyelletso ea lihlopha tsa hydroxethl ka kamoreng e ka morao ea selefounu le li e etsa polymer ea bohlokoa lits'ebetsong tse thehiloeng metsing. Sebopeho sa limolek'hule le thepa ea hec e tla tšohloa ka botlalo.
Slubility ea Hec ka metsing:
Lintlha tsa 3.1 tse amang qubu:
Sebaka sa Hec ka metsing se na le lintlha tse 'maloa, ho kenyelletsa mocheso, pH le ho tsepamisa maikutlo. Lintlha tsena le litlamorao tsa bona ho HEC Kutloelo e tla tšohloa, li tla tšohloa ka mokhoa o fanang ka temohisiso ea maemo a ratang semoplutions.
3.2 Sporlity
Ho utloisisa meeli e kaholimo le e tlase ea li-allubility ea hec ka metsing ho bohlokoa ho theha likolobe ka ts'ebetso e nepahetseng. Karolo ena e tla kena libakeng tse mahlomoleng moo a bonts'ang tharollo e phahameng le litlamorao tsa ho feta meeli ena.
Nchafatsa Viscosity le Hec:
4.1 Karolo ea Hec in Viscosity:
Hec o sebelisoa e le thipa ea bosholu ba metsi ho thusa ho eketsa liketsahalo le ho ntlafatsa boitšoaro ba Rheological. Mekhoa ea hore na phc e fihlela taolo ea lipompo e tla hlahlojoa, e hatisa ka ho sebelisana le limoleke tsa metsi le li-motsoako tse ling ka mokhoa oa ho hlasela.
4.2 Phello ea mefuta-futa ea foromo ho Viscosity:
Lintho tse fapaneng tse fapaneng, ho kenyeletsa le ho tsepamisa mohopolo, mocheso, mocheso le sheathe, ho ka ama liketsahalo tsa bosholu ba metsi. Karolo ena e tla sekaseka phello ea mefuta ena mabapi le pono ea li-arcose tse nang le lipehelo tsa Hec-
Likopo le litebello tse tlang:
5.1 Likopo tsa indasteri:
Hec e sebelisoa haholo likopi tse fapaneng tsa indasteri ea li indasteri e kang petso, lidheres le bahalelants. Karolo ena e tla totobatsa menehelo e khethehileng ea Hec ho Mekhopo ea Metsi Likopong tsena mme o buisane ka melemo ea eona ka li-thickered.
5.2 Litataiso tsa lipatlisiso ka nako e tlang:
Ha litlhokahalo tsa likokoana-hloko tse tsitsitseng le tse phahameng li ntse li tsoela pele ho hola, tataiso ea kamohelo ea nako e tlang ea pelehi ea li-hec-li-hec tse tla hlahlojoa. Sena se ka kenyelletsa ho thetsoa ho Hcc, mokhoa oa ho qala mekhoa, le mekhoa e tsoetseng pele e tsoetseng pele.
ha re phethela:
Ho akaretsa se fumanoeng se atlehang, karolo ena e tla totobala bohlokoa ba taolo ea qhobosheane ea bakokoli ea kutloano e ntseng e le likheo tsa metsi a sebelisa Hec. Sengoliloeng sena se tla phethela ka se boleloang se sebetsang bakeng sa li-batsebi le liletsa hore li ntlafatse tumelo ea litsamaiso tsa metsi.
