Izinsimbi ezizilinganisa ngokwazo ziya ngokuya zithandwa embonini yezokwakha ngenxa yokusebenziseka kalula, izakhiwo ezinhle kakhulu zokugeleza, kanye nekhono lokuhlinzeka ngobushelelezi, indawo eyisicaba.Phakathi kwezithako ezahlukahlukene ezisetshenziswa osimeni abazilinganisa, i-hydroxypropyl methylcellulose (HPMC) idlala indima ebalulekile ekulawuleni i-viscosity.
Udaka oluzilinganisa lunedumela embonini yezokwakha ngekhono laso lokudala indawo ebushelelezi, eyisicaba ngomzamo omncane.Lezi zinto zinikeza izinzuzo ezibalulekile kunezindlela ezijwayelekile zokulinganisa, njengokusebenziseka kalula, ukoma ngokushesha nokuhambisana nezinhlobonhlobo zama-substrates.Isihluthulelo sokusebenza kwe-self-leveling mortar ukulawula okunembile kwezakhiwo ze-rheological, ikakhulukazi i-viscosity, ethinta ngokuqondile ukugeleza nokulinganisa izakhiwo.
1.Iqhaza le-HPMC kudaka lokuzilinganisa:
IHydroxypropylmethylcellulose (HPMC) i-ether cellulose evame ukusetshenziswa njenge-thickener ne-rheology modifier ezintweni zokwakha.Emasikeni azilinganisa wona, i-HPMC yenza imisebenzi eminingi, ehlanganisa ukugcinwa kwamanzi, ukusebenza okuthuthukisiwe, nokulawula i-viscosity.I-viscosity ephansi I-HPMC ibaluleke kakhulu njengoba ihlinzeka ngokugeleza okungcono kanye nokulinganisa ngenkathi igcina ukugcinwa kwamanzi okwanele kanye nezakhiwo zemishini.
2. Ukubaluleka kwe-viscosity ephansi ye-HPMC:
Ukugeleza okuthuthukisiwe: I-viscosity ephansi I-HPMC isiza ukugeleza kodaka oluzilinganisa ngokwalo, lizivumela ukuthi zisakazeke ngokulinganayo phezulu futhi zigcwalise ngempumelelo izikhala kanye nokukhubazeka.Lokhu kubangela ukushelela, ukuqeda okufanayo, ukunciphisa isidingo sokulungiswa okwengeziwe kwendawo.
Ukusebenza okuthuthukisiwe: Izithako ezizilinganisayo eziqukethe i-HPMC ene-viscosity ephansi kulula ukuxutshwa, ukupompa nokuthululwa, ukuthuthukisa ukusebenza kahle kanye nokunciphisa izidingo zabasebenzi.Osonkontileka bangazuza ukukhiqiza okukhulu nokusebenza kahle phakathi nenqubo yokufaka isicelo.
Yehlisa ubungozi bokuhlukaniswa: Izithasiselo ze-viscosity eziphezulu zingadala izinkinga zokuhlukaniswa, okuwukuxazulula ngokungalingani kwama-aggregates engxubeni yodaka.I-viscosity ephansi ye-HPMC isiza ukuvimbela ukuhlukana, iqinisekisa ukufana nokuvumelana emkhiqizweni wokugcina.
Nciphisa ukubambeka komoya: I-Viscosity ephakeme kakhulu ingabamba amabhamuza omoya ku-matrix yodaka, ibeke engcupheni amandla nokuqina kwento.Ngokusebenzisa i-HPMC ye-viscosity ephansi, ubungozi bokungena emoyeni buyancipha, okuholela endaweni eminyene, ehlala isikhathi eside.
Ukuhambisana Nezisetshenziswa Zokumpompa: Izinsimbi ezizilinganisa ngokwazo ngokuvamile zidinga ukumpompa izinhlelo ezinkulu.Ifomula ye-HPMC ye-viscosity ephansi iyahambisana nezisetshenziswa zokumpompa ukuze zilethwe ngendlela ephumelelayo, eqhubekayo ngaphandle kokuvala.
3. Izinto ezithinta i-viscosity:
Kunezici ezimbalwa ezingathinta i-viscosity ye-self-leveling mortar, kuhlanganise:
Uhlobo lwe-polymer nesisindo se-molecular: Uhlobo nesisindo samangqamuzana e-HPMC sinomthelela omkhulu ku-viscosity.Ama-polymers anesisindo esiphansi avame ukukhombisa ama-viscosity aphansi, kuyilapho ama-polymers esisindo samangqamuzana aphezulu angase abangele ukwanda kwe-viscosity.
Okuqukethwe kwe-polymer: Ukugxila kwe-HPMC ekwakhekeni kodaka kuthinta i-viscosity, ngokugxila okuphezulu ngokuvamile okuholela ekubonakaleni okuphezulu.
Usayizi wezinhlayiyana nokusabalalisa: Usayizi wezinhlayiyana nokusatshalaliswa kwezingxenye eziqinile (isb. usimende neqoqo) kuthonya ukuziphatha kwe-rheological kodaka oluzilinganisa ngokwalo.Izinhlayiya ezinhle zingasiza ekwandiseni i-viscosity ngenxa yokwanda kwendawo kanye nokusebenzisana kwezinhlayiyana.
Isilinganiso samanzi ne-binder: Isilinganiso samanzi kokuhlanganisayo (kuhlanganise ne-HPMC) sithinta ngokuqondile uketshezi kanye ne-viscosity yodaka oluzilinganisa.Ukulungisa isilinganiso samanzi ku-binder kuvumela ukulawula okunembile kwe-viscosity nezici zokugeleza.
Inqubo Yokuxuba: Inqubo efanele yokuxuba, okuhlanganisa ukuxuba isikhathi nesivinini, ingathinta ukuhlakazeka kwe-HPMC ku-matrix yodaka, ngaleyo ndlela kuthinte i-viscosity kanye nokusebenza okuphelele.
4. Thola ukwakheka kwe-HPMC ye-viscosity ephansi:
Ukuthola ukwakheka kwe-viscosity ephansi ye-HPMC yodaka lokuzilinganisa, amasu amaningana angasetshenziswa:
Ukukhetha Ibanga Elilungile le-HPMC: Abakhiqizi bangakhetha amabanga e-HPMC anesisindo samangqamuzana aphansi namaphrofayela e-viscosity enziwe ngokwezifiso ukuze ahlangabezane nezidingo ezithile zohlelo lokusebenza.
Ukuthuthukisa Iresiphi: Ukulungisa kahle izithako zodaka oluzilinganisa, okuhlanganisa izinhlobo nezilinganiso zezithako, kungasiza ekufinyeleleni ibanga le-viscosity elifunekayo.
Ukwengezwa kwama-dispersants: Ukwengezwa kwama-disperants noma ama-defoamers kungathuthukisa ukuhlakazwa kwe-HPMC kungxube yodaka, kunciphise i-viscosity futhi kunciphise ukungena komoya.
Ukusetshenziswa kokuxuba okuphezulu kwe-shear: Imishini ephezulu yokuxuba i-shear ingakhuthaza ukuhlakazeka komfaniswano we-HPMC nezinye izithasiselo, ithuthukise uketshezi, futhi inciphise i-viscosity.
Ukulawula izinga lokushisa: Izinga lokushisa lithinta izakhiwo ze-rheological zodaka oluzilinganisa.Ukulawula izinga lokushisa ngesikhathi sokuxuba nokusebenzisa kusiza ukufeza i-viscosity oyifunayo kanye nezici zokugeleza.
5. Amathrendi namathemba esikhathi esizayo:
Ukuthuthukiswa kokwakheka kwe-HPMC okune-viscosity ephansi yezinsimbi ezizilinganisa ngokwazo kulindeleke ukuthi kuqhubeke njengoba abakhiqizi belwela ukuthuthukisa ukusebenza, ukusimama kanye nokusebenziseka kalula.Okuthrendayo kwesikhathi esizayo kungase kuhlanganise:
Ukuhlanganiswa kwezithako ezisimeme: Ukugxila okukhulayo kokusimama kungase kuqhube ukwamukelwa kwezinto ezisekelwe ku-bio-based noma ezigaywe kabusha njengezinye izithasiselo zendabuko, okuhlanganisa i-HPMC.
I-Advanced Rheology Modifiers: Ukucwaninga okuqhubekayo kuzilungisi ezintsha ze-rheology nezithasiselo kungase kuholele ekuthuthukisweni kokwakheka okusebenza ngempumelelo ukuze kuzuzwe ama-viscosity aphansi kanye nezakhiwo zokugeleza ezithuthukisiwe.
Ukumodela kwedijithali nokulingisa: Intuthuko kumodeli yedijithali nobuchwepheshe bokulingisa ingasiza ukuthuthukiswa kokwakheka kodaka oluzilinganisa ngokwakho, okuvumela ukulawula okunembe kakhudlwana kwe-viscosity nokusebenza.
Izixazululo ezenziwe ngokwezifiso zezinhlelo zokusebenza ezithile: Abakhiqizi banganikeza izixazululo ezenziwe ngokwezifiso zezidingo ezithile zohlelo lokusebenza, ezifana nosimende okusetha ngokushesha amaphrojekthi azwela isikhathi noma ukwakheka kothuli oluphansi lwezindawo zasendlini.
I-viscosity ephansi I-HPMC idlala indima ebalulekile ekusebenzeni kwezithako ezizilinganisa ngokwazo, ithuthukisa ukugeleza, ukusebenza kahle nokuvumelana.Ngokulawula ngempumelelo i-viscosity, abakhiqizi bangakhiqiza izinsimbi ezinezindawo ezibushelelezi, eziyisicaba ezinomzamo omncane kanye nokusebenza kahle okuphezulu.Njengoba imboni yezokwakha iqhubeka nokuvela, ukuthuthukiswa kokwakheka kwe-HPMC okune-viscosity ephansi kusabalulekile ukuze kuhlangatshezwane nesidingo esikhulayo sezisombululo zokulinganisa ezisezingeni eliphezulu nezisebenziseka kalula.
