IHydroxypropylmethylcellulose (HPMC) sisithako esibalulekileyo kwi-mortar, esidlala indima ebalulekileyo ekuphuculeni ukusebenza kwe-mortar. Njengesixhobo esingenabungozi, esingangcolisiyo nesinobuhlobo nokusingqongileyo, i-HPMC iye yathatha indawo yezithako zemveli ezifana ne-starch ether kunye ne-lignin ether kushishino lokwakha. Eli nqaku liza kuxoxa ngendima ebalulekileyo ye-HPMC kwi-mortar kwiinkalo ezintathu zokugcina amanzi, ukusebenza kakuhle kunye nokuhambelana.
I-HPMC inokuphucula ngempumelelo ukugcinwa kwamanzi kwi-mortar. Ukugcinwa kwamanzi kwi-mortar kubhekisa kubuchule be-mortar bokugcina umxholo wamanzi ngexesha lokwakhiwa. Ukugcinwa kwamanzi kwi-mortar kunxulumene nokusebenza kwesamente kunye nezongezo ezisetyenziswa kwi-mortar. Ukuba i-mortar ilahlekelwa ngamanzi amaninzi, iya kubangela ukuba i-mortar yome, nto leyo eya kunciphisa kakhulu ukusebenza kwayo kunye nokunamathela kwayo, kwaye ibangele neengxaki ezifana nokuqhekeka kwimveliso egqityiweyo.
I-HPMC ine-hydroxypropyl kunye namaqela e-methyl kwaye ithanda kakhulu amanzi. Ingenza umaleko wefilimu engaphezulu kumphezulu wee-mortar particles ukuthintela ukufuma kwamanzi kunye nokuphucula ngokufanelekileyo ukugcinwa kwamanzi kwi-mortar. Kwangaxeshanye, i-HPMC inokudibana nee-molecules zamanzi ngokusebenzisa iibhondi ze-hydrogen, okwenza kube nzima ngakumbi ukuba ii-molecules zamanzi zahlukane nee-mortar particles. Ke ngoko, i-HPMC inefuthe elibalulekileyo ekuphuculeni ukugcinwa kwamanzi kwi-mortar.
I-HPMC inokuphucula ukusebenza kakuhle kwe-mortar. Ukusebenza kakuhle kwe-mortar kubhekisa ekubeni kulula kangakanani ukusetyenziswa kwe-mortar ngexesha lokwakha. Okukhona ukusebenza kakuhle kwe-mortar, kokukhona kulula kubasebenzi bokwakha ukulawula imo kunye nokuhambelana kwe-mortar ngexesha lenkqubo yokwakha. Ukusebenza kakuhle kwe-mortar kunokunciphisa inani leepokotho zomoya kwimveliso egqityiweyo, okwenza isakhiwo sibe xinene kwaye siqine.
I-HPMC inokuphucula ukusebenza kakuhle kwe-mortar ngokunciphisa i-viscosity ye-mortar. Ubunzima be-molecular ye-HPMC buphezulu kakhulu, kwaye kulula ukwenza ii-hydrogen bonds kunye nee-molecule zamanzi, nto leyo ebangela i-viscosity ephezulu. Nangona kunjalo, i-HPMC inokubola ibe zii-particles ezincinci phantsi kwesenzo samandla okucheba, kunciphisa i-viscosity ye-mortar. Ke ngoko, xa abasebenzi bokwakha bephatha i-mortar, ii-particles ze-HPMC ziya kwahlulwa, nto leyo eyenza i-mortar ibe manzi ngakumbi kwaye kube lula ukuyakha. Ngaphezu koko, amaqela e-hydrophilic kwi-HPMC anokwenza ifilimu yomphezulu phezu kwee-particles ze-mortar, anciphise ukungqubana phakathi kwee-particles ze-mortar, kwaye aphucule ngakumbi ukusebenza kwe-mortar.
I-HPMC inokuphucula ukunamathela kwesamente. Ukunamathela kwesamente kubhekisa kubuchule bayo bokunamathela ngokuqinileyo kumphezulu wesamente. Ukunamathela okuhle kunokwenza unxibelelwano oluqinileyo noluthembekileyo phakathi kwesamente kunye nesamente, okuqinisekisa ukuqina kwemveliso egqityiweyo. Ukongeza, ukunamathela okuhle kunokwenza umphezulu wemveliso egqityiweyo ube mpuluswa kwaye ube mhle ngakumbi.
I-HPMC inokuphucula ukunamathelana kwesamente ngeendlela ezahlukeneyo. Okokuqala, i-HPMC inokwenza ifilimu yomphezulu kumphezulu wesamente emva kokwakhiwa kwesamente, nto leyo enokunciphisa ngempumelelo uxinzelelo lomphezulu wesamente kwaye yenze kube lula ukuba isamente inamathele kwisamente. Okwesibini, amasuntswana e-HPMC anokwenza nesakhiwo senethiwekhi kumphezulu wesamente, andise indawo yoqhagamshelwano phakathi kwesamente kunye nesamente, kwaye aphucule ngakumbi ukunamathela kwesamente. Ngaphezu koko, amaqela athanda amanzi kwi-HPMC anokudityaniswa neemolekyuli zamanzi, ezinokunyusa ngempumelelo umlinganiselo wamanzi nesamente yesamente kwaye ziphucule ngakumbi amandla adibeneyo esamente.
Ukusetyenziswa kwe-HPMC kwi-mortar kuneengenelo ezininzi ezifana nokugcinwa kwamanzi, ukusebenza kakuhle, kunye nokunamathela okuphuculweyo. Ezi ngenelo azizuzisi abasebenzi bokwakha kuphela, kodwa zikwanefuthe elihle kumgangatho wemveliso egqityiweyo. Ngophuhliso lwesayensi netekhnoloji, kukholelwa ukuba i-HPMC iya kudlala indima ebaluleke ngakumbi kushishino lokwakha kwaye ibonelele ngezixhobo ezisebenzayo nezikhuselekileyo ngakumbi kushishino lokwakha.
