I-Carboxymethyl Cellulose (CMC) kwi-Dry Mortar kuLwakhiwo

I-Carboxymethyl cellulose (CMC) isetyenziswa ngokuqhelekileyo kwimixube yodaka olomileyo kwishishini lokwakha ngenxa yeempawu zayo ezizodwa. Nantsi indlela iCMC esetyenziswa ngayo kudaka olomileyo:

1. Ukugcinwa kwamanzi: I-CMC isebenza njenge-arhente yokugcina amanzi kwimixube yodaka olomileyo. Inceda ukuthintela ukulahleka kwamanzi ngokukhawuleza ngexesha lokuxuba kunye nokusetyenziswa, ukuvumela ukuphuculwa kokusebenza kunye nexesha elivulekileyo elongezelelweyo. Oku kuqinisekisa ukuba udaka luhlala lune-hydrated ngokwaneleyo ukuze lunyangelwe ngokufanelekileyo kunye nokunamathela kwi-substrates.
2. Ukuphuculwa kokuSebenza: Ukongezwa kwe-CMC kuphucula ukusebenza kodaka olomileyo ngokunyusa ukuhambelana kwayo, ukusasazeka, kunye nokulula kwesicelo. Inciphisa ukutsalwa kunye nokuchasana ngexesha lokuxubha okanye ukusabalalisa, okukhokelela kwisicelo esilula kunye nesifanayo kwiindawo ezithe nkqo okanye ngaphezulu.
3. Ukubambelela okongeziweyo: I-CMC iphucula ukuncamathelwa kodaka olomileyo kwii-substrates ezahlukeneyo, ezifana nekhonkrithi, i-masonry, iinkuni kunye nentsimbi. Iphucula amandla ebhondi phakathi kodaka kunye ne-substrate, ukunciphisa umngcipheko we-delamination okanye i-detachment ngexesha.
4. Ukuncitshiswa kwe-Shrinkage kunye nokuCaphuka: I-CMC inceda ukunciphisa ukucutheka kunye nokuqhekeka kwidaka elomileyo ngokuphucula ukubumbana kwayo kunye nokunciphisa ukukhupha kwamanzi ngexesha lokunyanga. Oku kubangela udaka oluhlala ixesha elide nolukwaziyo ukumelana ne-crack olugcina ingqibelelo yalo ekuhambeni kwexesha.
5. Ixesha lokumisela eliLawulwayo: I-CMC ingasetyenziselwa ukulawula ixesha lokumisela udaka olomileyo ngokuhlengahlengisa izinga lokugalela kunye neempawu ze-rheological. Oku kuvumela iikontraka ukuba zilungelelanise ixesha lokumisela ukuze lihambelane neemfuno zeprojekthi kunye neemeko zokusingqongileyo.
6. I-Rheology eyomeleziweyo: I-CMC iphucula iipropathi zerheological zokwenziwa kodaka olomileyo, olufana ne-viscosity, i-thixotropy, kunye nokuziphatha kokucheba. Iqinisekisa ukuhamba okuhambelanayo kunye neempawu zokulinganisa, ukuququzelela ukusetyenziswa kunye nokugqitywa kodaka kwiindawo ezingaqhelekanga okanye eziqingqiweyo.
7. UkuPhuculwa kweSandability kunye nokuQeda: Ubukho be-CMC kudaka olomileyo buphumela kwimigangatho egudileyo nefanayo, ekulula ukuyisanti kunye nokugqiba. Inciphisa uburhabaxa bomphezulu, i-porosity, kunye neziphene zomhlaba, okubangela ukugqitywa komgangatho ophezulu olungele ukupeyinta okanye ukuhlobisa.

ukongezwa kweCarboxymethyl cellulose (CMC) ukomisa ukwakhiwa kodaka kuphucula ukusebenza kwabo, ukusebenza, ukuqina, kunye nobuhle, okwenza ukuba bafaneleke ngakumbi kuluhlu olubanzi lwezicelo zokwakha, kubandakanywa ukulungiswa kweetayile, i-plastering, kunye nokulungiswa kwendawo.
