I-HPMC ilungelelanisa ubumanzi bodaka

Njengesixhobo sokwakha esisetyenziswa ngokubanzi kwishishini lokwakha, udaka ludlala indima ebalulekileyo yesakhiwo kunye nokusebenza. I-fluidity yodaka sesinye sezibonakaliso ezibalulekileyo ezichaphazela ukusebenza kwayo kolwakhiwo. I-fluidity elungileyo inegalelo ekwenzeni lula imisebenzi yokwakha kunye nomgangatho wesakhiwo. Ukuze kuphuculwe ubumanzi kunye nokusebenza kodaka, izongezo ezahlukeneyo zihlala zisetyenziselwa ukulungiswa. Phakathi kwabo,ihydroxypropyl methylcellulose (HPMC), njengento eqhelekileyo esetyenziswa ngokuqhelekileyo i-polymer compound yamanzi, idlala indima ebalulekileyo kumdaka. .

Iimpawu ezisisiseko ze-HPMC: I-HPMC yimathiriyeli yepolima enyibilikayo emanzini eyenziwe kwiselulosi yendalo eguqulwe ngokwemichiza. Inokuqina okugqwesileyo, i-gelling, ukugcinwa kwamanzi kunye nezinye iimpawu. Ayinyibiliki emanzini, kodwa inokwenza isisombululo se-viscous emanzini, ngoko isoloko isetyenziselwa ukwakhiwa, iingubo, amayeza kunye nezinye iindawo. Xa isetyenziswe njengesongezo sodaka, i-HPMC inokuphucula ngokufanelekileyo ukumanzi, ukugcinwa kwamanzi kunye nokusebenza kodaka.

Iimpembelelo zendlela ye-HPMC kumanzi odaka:

Isiphumo sokuqina: I-HPMC ngokwayo inesiphumo esibonakalayo sokujiya. Xa ifakwe kwidaka, inokunyusa kakhulu i-viscosity yodaka. Umphumo wokuqina ubangelwa iimolekyuli ze-HPMC ezenza isakhiwo sothungelwano emanzini, esithatha amanzi kunye nokwandisa, ukwandisa i-viscosity yesigaba samanzi. Le nkqubo ivumela i-fluidity yodaka ukuba ilungiswe. Xa umxholo we-HPMC kumdaka uphezulu, ukuhamba kwamanzi okukhululekile kuya kuthintelwa kwinqanaba elithile, ngoko ke ubuninzi be-fluidity bodaka luya kubonisa utshintsho oluthile.

Ukuphucula ukugcinwa kwamanzi: I-HPMC inokwenza ifilimu ebhityileyo kwidaka ukunciphisa ukuphuphuma kwamanzi kunye nokuphucula ukugcinwa kwamanzi kumdaka. Udaka olunokugcinwa kakuhle kwamanzi lunokugcina ukusebenza ixesha elide, nto leyo ibalulekileyo ukuze kube lula ukwakha ngexesha lolwakhiwo. Ukugcinwa kwamanzi aphezulu kunokuthintela udaka ukuba lome ngaphambi kwexesha kwaye luphucule ixesha lokwakha kunye nokusebenza kakuhle kodaka.

Ukusasazwa: I-HPMC inokwenza isisombululo se-colloidal emanzini, esinokuphucula ukusabalalisa phakathi kwezinto zodaka. I-fluidity yodaka ayihambelani kuphela nomlinganiselo wesamente, isanti kunye ne-admixtures, kodwa inxulumene ngokusondeleyo nokusasazwa kwezi zixhobo. Ngokulungelelanisa ubungakanani be-HPMC, amacandelo kumdaka angasasazwa ngokulinganayo, ngaloo ndlela kuphuculwe ngakumbi ubumanzi.

Umphumo weGelling: I-HPMC inokukhuthaza ukusasazwa ngakumbi kwamasuntswana kumdaka kunye nokuphucula ukuzinza kwesakhiwo sayo. Ngokuphucula umphumo we-gelling, i-HPMC inokugcina umbane ozinzileyo wodaka ngexesha lokugcinwa kwexesha elide kwaye ugweme ukuhla kwe-fluidity ngenxa yokulibaziseka kwexesha.

Impembelelo yokuphucula iPlastiki: Ukongezwa kwe-HPMC kunokunyusa iplastiki yodaka, iyenze kube lula ukusebenza kwaye ibe neplastiki engcono ngexesha lenkqubo yokwakha. Umzekelo, xa utyabeka udonga, ukumanzi okufanelekileyo kunye neplastiki kunokunciphisa ukuvela kweentanda kunye nokuphucula umgangatho wokutyabeka.

Usetyenziso olulungiselelweyo lwe-HPMC kuhlengahlengiso lwe-mortar fluidity:

Ulawulo lwedosi: Idosi ye-HPMC ichaphazela ngokuthe ngqo ubumanzi bodaka. Ngokuqhelekileyo, xa isixa esongezelelweyo se-HPMC siphakathi, ukumanzi kunye nokugcinwa kwamanzi odaka kunokuphuculwa kakhulu. Nangona kunjalo, i-HPMC egqithisileyo inokubangela ukuba i-viscosity yodaka ibe phezulu kakhulu, nto leyo enciphisa ubumanzi bayo. Ke ngoko, isixa se-HPMC esongeziweyo kufuneka silawulwe ngokuchanekileyo ngokweemfuno ezithile kwizicelo.

I-Synergy kunye nezinye ii-admixtures: Ukongeza kwi-HPMC, ezinye ii-admixtures zihlala zongezwa kwi-mortar, njenge-superplasticizers, i-retarders, njl njl. ngesondo. Ngokomzekelo, i-superplasticizers inokunciphisa ubuninzi bamanzi kumdaka kwaye iphucule i-fluidity yodaka, ngelixa i-HPMC inokuphucula ukugcinwa kwamanzi kunye nokusebenza kokwakhiwa ngelixa igcina i-viscosity yodaka.

Ukulungelelaniswa kweentlobo ezahlukeneyo zodaka: Iindidi ezahlukeneyo zodaka zineemfuno ezahlukeneyo zokumanzi. Umzekelo, udaka lokutyabeka luneemfuno eziphezulu zokumanzi, ngelixa udaka lwe-masonry lunika ingqwalasela engakumbi kwikhonkco kunye nobukhulu. Ngexesha lale nkqubo, isixa kunye nohlobo lwe-HPMC eyongeziweyo kufuneka luphuculwe kwaye luhlengahlengiswe ngokweemfuno zodaka ezahlukeneyo ukuqinisekisa ulwelo olululo kunye nokulinganisela.

Njengesihlomelo sodaka esisetyenziswa ngokuqhelekileyo,HPMCiyakwazi ukulungelelanisa ngokufanelekileyo umbane wodaka ngokuqina, ukugcinwa kwamanzi, ukusabalalisa, i-gelling, njl. Nangona kunjalo, idosi ye-HPMC kufuneka ihlengahlengiswe ngokuchanekileyo ngokwemiqathango yesicelo esithile ukuphepha ukusetyenziswa okugqithisileyo okukhokelela ekunciphiseni ukumanzi. Ngophuculo oluqhubekayo lweemfuno zokusebenza kodaka kushishino lokwakha, isiphumo esilawulayo se-HPMC sinethemba elibanzi losetyenziso kwixesha elizayo.
