Ibintu bigira ingaruka ku bucucike bw'ibisubizo bya HEC: Ibisobanuro by'ingenzi ku ikoreshwa ry'inganda

1.Uburemere bwa molekile n'urwego rwa polymerization

Uburemere bwa molekile bwa HEC bugira ingaruka ku buryo butaziguye ku buryo bworoshye. Polima nyinshi zipima uburemere bwa molekile zikora iminyururu miremire, ifata cyane mu gisubizo, bigatera kwiyongera kwa viscosity. Urugero, ubushakashatsi bwerekana ko HEC ifite urwego rwo hejuru rwa polymerization (DP) ikora imiterere ikomeye isa na gel, yongera uburyo amazi abikwa muri mortiers zishingiye kuri sima. Ikoreshwa mu nganda akenshi risaba kuringaniza uburemere bwa molekile n'ubushobozi bwo gukora - DP HEC nyinshi ishobora kunoza uburyo bwo gufatana ariko ishobora kubangamira urujya n'uruza rw'imyuka igenda yiyongera.

2.Ubwinshi bwa HEC mu gisubizo

Ubushyuhe bwiyongera cyane iyo HEC iri ku rugero ruto. Iyo iri ku rugero ruto (urugero, 0.2–0.5% mu byuma bya sima), HEC ikora amazi ya pseudoplastic agumana ubushobozi bwo gukora mu gihe arwanya kugwa. Ariko, kurenza urugero rwiza (urugero, >1%) bishobora gutuma habaho ububyimba bwinshi, bikagorana kuvanga no gukoresha. Ubushakashatsi ku buryo bwa HEC-alumina bwerekana ko HEC ya 500 ppm itera imbaraga cyane mu guhagarara hakoreshejwe uburyo bwa steric, ariko ubunini buke (100 ppm) busaba surfactants kugira ngo igire ingaruka nk'izo.

3.Ingaruka z'ubushyuhe

Imurikagurisha ry'ibisubizo bya HECubushyuhe bushingiye ku bushyuheUko ubushyuhe bwiyongera, iminyururu ya polymer iragabanuka bitewe no kugabanuka k'ubufatanye bwa hydrogen, bigagabanya ingano n'ubushyuhe bwa hydrodynamic. Urugero, kuri 40°C, ubushyuhe bwa HEC bushobora kugabanukaho 30–50%, bigira ingaruka ku mikorere mu bihe bishyushye. Ariko, HEC igumana ubuziranenge kugeza kuri 90°C, bigatuma ikoreshwa mu bikorwa bishyuha cyane nko gucukura peteroli.

4.Igipimo cyo gukata no gukora imyitwarire ya Pseudoplastic

Ibisubizo bya HEC nigukata icyuma, bivuze ko ubushyuhe bugabanuka iyo habayeho imbaraga za mekanike (urugero, kuvanga cyangwa kuvoma). Iyi miterere ituma byoroha gukoresha mu mavuta n'irangi mu gihe bikomeza guhuza neza. Urugero, gusiga ibumba hakoreshejwe HEC bikomeza gukora neza mu gihe cyo gukurura ariko bikarinda kugwa nyuma yo gukoresha.

5.pH na Ionic Strength

Imiterere ya HEC idakoresha ioni ituma idakomera cyane kuri pH ugereranije na polimeri za ioni. Ariko, urugero rwa pH rukabije cyangwa imbaraga nyinshi za ioni bishobora guhindura imikorere y'umuti. Mu bihe bya aside (pH

6.Inyongeramusaruro n'ibindi bifitanye isano

Kuba hari ibinyobwa bya ionic, surfactants, cyangwa umunyu bihindura ubukana bwa HEC. Urugero:

• Ibinyobwa bya Ionic: Kongeramo 1-butyl-3-methylimidazolium bromide bigabanya ubukana bwa HEC binyuze mu kubangamira imikoranire ya polymer n'amazi.
• Surfactants: Surfactants zitari ionic (urugero, Tween 80) zituma habaho kongera gukora neza HEC zumye mu buryo bukonje.
