Isiphumo seHMC Hydroxyyl Methyl Sellulose kwi-Cement Hydration

I-HEMC (i-Hydroxyyl Methyl Selelose) yi-polyul ye-polymer ye-polymer esetyenziswayo esetyenziswa rhoqo kwizinto zokwakha. I-ikakhulu idlala indima ekuphuculeni ulwahlulelo lwe-quayity paste kunye nokulibaziseka kwesakhiwo sokuhambisa i-qumed. Kwinkqubo ye-hydration yesamente, i-HMC inempembelelo ethile kwi-hydrations yokuphendula kunye nokusebenza kwesamente.

1. Iipropathi ezisisiseko ze-HEMC
I-HEMC yi-polymer eyenziwe ngokuguqula iikhemikhali kweselutase yendalo. Isakhiwo sayo semolekyuli siqulethe izinto ezimbini, i-HYDROXYETYL NE-Methyl, eyenza ukuba ihlale kakuhle, ubuchule bokuhlengahlengiswa kobuchule kunye neempawu zokwenza ifilimu. Njengomqanda wesamente, i-HMC inokuphucula ulwelo lwayo, ukusebenza kwayo, kunye nokusebenza kwesamente inamandla, kwaye kunokuphucula amandla kunye nokuqina emva kokukhanya kwinqanaba elithile.

2. Isiphumo se-HEMC kwiNkqubo yeHydration
I-qumed hydration yinkqubo yesamente kunye nokuphendula kwamanzi. Ngale ndlela yokuphendula, ngokuthe ngcembe i-Contest ngokuthe chu ukwenza i-quetrix eqinileyo. Njengomqanda, i-HMC inokudlala iintlobo ezahlukeneyo zenkqubo hydration. Iziphumo ezithile zezi zilandelayo:

2.1 Ukuphucula ubulwele kwi-slidity yesamente
Kwinqanaba lokuqala le-qumedym hydration, ulwelo lwesamente i-slide lihlwempuzekile, elinokuchaphazeleka ngexesha lokwakha. I-HMC inokuphucula ngokufanelekileyo ulwahlulelo lwesamente yesamente ngenxa yophawu lwayo oluphezulu kunye nokuluka kakuhle kwamanzi. Isasaza amasuntswana amasuntswana kwaye inciphisa ukudityaniswa phakathi kwamasuntswana athi, elenza ukuba kuphuculwe ukungqinelana kwesamente etyibilika, kwenza kube lula ukusebenza.

2.2 Ukulibaziseka kwe-Hydration Impendulo
Iqela le-hydroxyyl kwi-hemc linombala oqinileyo. Inokwenza ifilimu ye-hydding kumphezulu wamasuntswana wezamente, icothe isantya soqhakamshelwano phakathi kwamasuntswana kunye namanzi, ngaloo ndlela sibayithintela inkqubo ye-qumed. Esi siphumo sokulibazisa sibaluleke kakhulu kubushushu obuphezulu okanye ukwakhiwa ngokukhawuleza. Ingathintela ukukhula okungalinganiyo ngenxa yesamente egqithileyo, kwaye unokwandisa ixesha lokwakha ukuphepha iingxaki zokumisa kwangoko.

2.3 Ukuphuculwa kozinzo lwesamente
Ngexesha lenkqubo ye-hydration yesamente i-slidery, i-HMC inokuphucula ngokufanelekileyo ukuzinza kwe-slirry. Amaqela e-hydroxyyteyl kunye ne-methyl kwimolekyuli yeHMC anokunxibelelana ne-cersussussunts i-hydrogen bonds kunye ne-van der imbonakalo yokwakha isakhiwo esizinzileyo. Olu qini lunceda ukuthintela ukuxhathisa kwi-qumetion, ngaloo ndlela kuphucule ukufana kwesamente kunye nokuqinisekisa uzinzo lwenkqubo ye-quadration Inkqubo yenkqubo yenkqubo yesamente.

2.4 Ukuphucula ukudweliswa kwemveliso ye-shydration
I-HMC inokuphucula ubume boludwe lweemveliso ze-qumences hydration ngokuhlengahlengiswa kolwelo kunye nokubonisa ukufakwa kwesamente. Umzekelo, kwinqanaba le-quation hydration, i-HMC inokuchaphazela ukwenziwa kunye nokusasazwa kweemveliso ze-hydration kwi-Calth ye-Calciate (Csh) i-gelcium yesilivere. Ngexesha lenkqubo ye-qumedy yesamente, ukwenziwa kwe-CSH I-Celty Gel yinto ephambili ekuqinisekiseni amandla kunye nokuqina kwesamente. I-HMC inokukhuthaza ukusasazwa kwe-CSH Gel kwaye kuphuculwe ukuxinana kunye namandla esamente ngokuhlengahlengisa ugxininiso lwe-ion kwi-quadration impendulo yesamente.

2.5 Impembelelo kumandla okwenza mandla
Iziphumo ze-HMC ekufumaneni amandla zihambelana kakhulu nenkqubo ye-quadration. Kwinqanaba lokuqala le-quation hydration, amandla okuqala kwesamente inokunciphisa kancinci ngenxa yefuthe lokugcina le-HMC. Nangona kunjalo, njengoko intetho yomzimba yesamente iyaqhubeka nokwenza isakhiwo se-geserser yesamente, ngaloo ndlela ukuphucula amandla okuqina ngexesha lonyango lwexesha elide. Ukongeza, i-HMC inokuphucula ukunganyangeki kwesamente, ukuphucula ukungafezeki kwesamente, kunye nokuphucula ukuqina kwesamente.

3. Ezinye iziphumo ze-HMC kwisamente
Ukongeza kwezi ziphumo zichazwe apha ngasentla kwiNkqubo yokuHlungatha kweSomtha, i-HMC ikwaneziphumo ezithile kwezinye iipropathi zesamente, ikakhulu zibandakanya:

3.1 Ukuphucula ukunganyangeki kweqanda kunye nokungafezeki kwesamente
I-HMC inokuphucula ubume besamente, ukuze ikwazi ukuvelisa i-Derix ye-Demer Gement ngexesha lenkqubo ye-hydration. Esi sakhiwo se-musesse sinokunciphisa ngokufanelekileyo ukuthambeka ngaphakathi kwesamente, ngaloo ndlela ukuphucula ukumelana neqabaka kunye nokungafezeki kwesamente. Phantsi kweemeko zemozulu ezigqithileyo, ukuxhathisa iqanda kunye nokungafezeki kwesamente kubaluleke kakhulu kwiindlela zexesha elide zezakhiwo.

3.2 Ukuphucula ukunganyangeki kwesamente
Kuba i-hemc iphucula ukuxinana kwesamente inamathisela, ikwazi ukunciphisa ngokufanelekileyo ubukho be-pores, igesi okanye irhasi, kwaye ke iphucule ukunyangwa kwesamente. Ingakumbi kwezinye iindawo ezinomswakama okanye ze-acid, i-HMC inokunceda ukwandisa ubomi benkonzo yezakhiwo zesamente.

I-4. Isixa kunye nesiphumo se-hemc
Iziphumo zexabiso le-HEMC kwiNkqubo yeHydration yeCedration yinto ephambili. Ngokubanzi, isixa se-HEMC esongeziweyo kufuneka silungiswe ngokweemfuno zezo nyani. Kakhulu i-HEMC inokubangela ukuba isamente ityhutyha ukuze sibe nokungqinelana okuphezulu kwaye kuchaphazele ukusebenza kwendlela yokwakha; Ngelixa ukongezwa okunganeleyo kusenokungadlali ngokupheleleyo kwindima yayo ekuphuculeni ukusebenza kwesamente. Ngokwesiqhelo, isixa se-HEMC esongezwe kwiSamente siyi-0,2% ukuya kwi-1.0% (nge-cememe), kwaye isixa esisetyenzisiweyo kufuneka simiselwe ngokweemeko ezahlukeneyo zesamente kwaye zisebenzise iimeko.

Njenge-qumestemmentition, i-HMC idlala indima ebalulekileyo ekuphuculeni ulwelo lwesamente ngelamente, ukulibazisa inkqubo ye-qumed yesamente, kunye nokuphucula ulwakhiwo kunye namandla edini. Ukusetyenziswa kwe-HMC kunokuphucula ukusebenza kwesamente ukuya kuthi ga kwinqanaba elithile, ngakumbi ekuphuculeni ukusebenza kwesamente, ukwandisa ixesha lokuziqhelanisa nexesha lokuziqhelanisa nesamente. Nangona kunjalo, isixa seHMC esisetyenziselwa ukuhlengahlengiswa ngokweemeko zokuqinisekisa ukusebenza kwayo kakuhle. Kwiiprojekthi zokwakha, ukusetyenziswa kwe-HMC kuya kunceda ukuphucula umgangatho kunye nokuqina kweemveliso zesamente.
