Uphuculo lwesiphumo sodaka lweHPMC kwiConcrete

Udaka yinxalenye ebalulekileyo ekwakhiweni kwaye lusetyenziswa ikakhulu ukubopha iibhloko zokwakha ezifana nezitena, amatye kunye neebhloko zekonkrithi. I-HPMC (i-Hydroxypropylmethylcellulose) yi-organic compound esetyenziswa njenge-additive in cement and mortar formulations. Kwiminyaka yakutshanje, i-HPMC ikhule ngokuthandwa njengomxube weekhemikhali kumdaka kunye nekhonkrithi. I-HPMC ineempawu ezininzi ezibalaseleyo ezenza kube lolona khetho lubalaseleyo kwizinto ezininzi zokwakha. Eli nqaku liza kuxoxa ngesiphumo sokuphucula udaka lwe-HPMC kwikhonkrithi.

Ukusebenza kweHPMC Mortar

Udaka lwe-HPMC luneepropati ezininzi ezigqwesileyo kwaye lucetyiswa kakhulu njengomxube wemichiza kwizinto zokwakha. I-HPMC yipolymer enyibilikayo yamanzi kwaye ayiyi kusabela okanye idibanise nezinye izinto kumxube. Le propati yandisa iplastiki kunye nokusebenza kodaka, okwenza kube lula ukuphatha nokusebenzisa. HPMC has adhesion ebalaseleyo kwiindawo ezahlukeneyo, nto leyo iluncedo kakhulu ekuphuculeni ukuqina kunye nokomelela kodaka. I-HPMC ilawula inkqubo yokufakwa kwamanzi kwikhonkrithi kunye nodaka. Le propathi ivumela i-HPMC ukuba isetyenziswe ukulawula ixesha lokumisela iidaka kunye nokuphucula amandla okugqibela odaka.

Uphuculo lwesiphumo sodaka lweHPMC kwiConcrete

Ukongeza i-HPMC kwikhonkrithi kunezibonelelo ezininzi zokomelela kokugqibela kunye nokuqina kwekhonkrithi. I-HPMC inciphisa umlinganiselo wesamente yamanzi, ngaloo ndlela inciphisa i-porosity yekhonkrithi kunye nokwandisa amandla ayo. Le propati yenza imveliso yokugqibela yekhonkrithi ibe nzima kwaye ixhathise ngakumbi kwizinto zangaphandle ezifana nemozulu kunye nokuhlaselwa kweekhemikhali. I-HPMC yandisa iplastiki yodaka, ngaloo ndlela iphucula ukusebenza kokugqibela kwekhonkrithi kunye nokuphucula inkqubo yokugalela. Ukusetyenzwa okongeziweyo okubonelelwa yi-HPMC kukwaqinisekisa ugutyulo olungcono jikelele lokomelezwa kwekhonkrithi.

I-HPMC inciphisa umthamo womoya obanjwe kwikhonkrithi, ngaloo ndlela inciphisa ukubonakala kweepores kunye nezithuba kwimveliso yokugqibela. Ngokunciphisa inani lee-pores, amandla oxinzelelo lwekhonkrithi ayanda, okwenza kube yinto ehlala ihleli kwaye iqinile. Okwesine, i-HPMC iphucula i-concrete hydration ngenxa yokumisela kwayo kunye neempawu zokuxinana. Ukuphuculwa kwe-hydration yekhonkrithi kuthetha ukomelela okukhulu kunye nokuqina kwimveliso yokugqibela, ukuyivumela ukuba imelane nezinto ezinzima zangaphandle.

I-HPMC inceda ukuthintela ulwahlulo lwekhonkrithi. Ukwahlula yinkqubo apho amacandelo ekhonkrithi ahlulwa omnye komnye ngenxa yeempawu zawo zomzimba. Ukwenzeka kokwahlula kunciphisa umgangatho wokugqibela wekhonkrithi kwaye kunciphisa amandla ayo. Ukongezwa kwe-HPMC kwimixube yekhonkrithi kwandisa ukudibanisa phakathi kwezinto eziqinileyo zomxube wekhonkrithi, ngaloo ndlela kuthintela ulwahlulo.

Udaka lwe-HPMC ludlala indima ebalulekileyo ekuphuculeni amandla okugqibela, ukuqina kunye nokusebenza kwekhonkrithi. Iinzuzo ze-HPMC kwizinto zokwakha ziye zaqatshelwa ngokubanzi kwaye zikhokelele ekusetyenzisweni kwazo ngokubanzi kwiiprojekthi zokwakha. Iimpawu ezigqwesileyo ze-HPMC zenza ukuba kunconywe kakhulu njengomxube wekhemikhali kudaka kunye nokwakheka kwekhonkrithi. Abakhi kufuneka babeke phambili ukusetyenziswa kodaka lwe-HPMC kwiiprojekthi zabo zokwakha ukunyusa ukuqina kunye nokuqina kwesakhiwo sokugqibela.
