HEMC FOR Dry Mixed Mortars

Kwimibhobho yomxube owomileyo, iHydroxyethyl Methylcellulose (HEMC) isebenza njengesongezo esibalulekileyo esibonelela ngeempawu ezahlukeneyo zokusebenza eziphucula ukusebenza komxube wodaka. Iimbumba zomxube owomileyo ziyimixube exutywe ngaphambili esetyenziselwa ukwakhiwa kwezicelo ezifana nokunamathiswa kweethayile, ukunikezelwa, i-plasters, kunye ne-grouts. Nantsi indlela i-HEMC eluncedo ngayo kumxube owomileyo wodaka:

1. Ukugcinwa kwamanzi: I-HEMC ineempawu ezigqwesileyo zokugcina amanzi, eziyimfuneko kumxube owomileyo. Inceda ukugcina amanzi ngaphakathi komxube wodaka, ukuthintela ukomiswa kwangaphambi kwexesha kunye nokuqinisekisa ukufakwa kwamanzi okwaneleyo kwezinto zesamente. Le propati iphucula ukusebenza, yandisa ixesha elivulekileyo, kwaye yandisa ukunamathela kwii-substrates.
2. Ukutyebisa kunye noLawulo lweRheology: I-HEMC isebenza njenge-thickener kunye ne-rheology modifier, echaphazela ukuhambelana kunye nokuziphatha kokuhamba komxube wodaka. Ngokulungelelanisa i-viscosity kunye neempawu ze-rheological, i-HEMC iququzelela iimpawu ezingcono zokusetyenziswa, ezifana nokuphucula ukusasazeka, ukunciphisa ukuthoba, kunye nokuqinisa ukubambisana.
3. UkuPhuculwa kokuSebenza okuPhuculweyo: Ubukho be-HEMC buphucula ukusebenza kodaka lomxube owomileyo, okwenza kube lula ukuxuba, ukusebenzisa, kunye nokuphatha. Ikhuthaza i-trowelability engcono, ivumela ukusetyenziswa okugudileyo kunye nokufana okufanayo kwimigangatho. Oku kubangela ukugqitywa komgangatho ophuculweyo kunye ne-aesthetics jikelele.
4. Ukuncitshiswa kwe-Shrinkage kunye ne-Cracking: I-HEMC inceda ukunciphisa i-shrinkage kunye nokuqhekeka kwimibhobho yomxube owomileyo ngokuphucula i-homogeneity yomxube kunye nokunciphisa izinga lokunyuka kwamanzi. Oku kunegalelo ekomeleleni kwexesha elide kunye nokunyaniseka kwesakhiwo sodaka olusetyenzisiweyo.
5. I-Adhesion eyandisiweyo: I-HEMC iphucula ukunamathela kodaka lomxube owomileyo kwii-substrates ezahlukeneyo, kubandakanywa ikhonkrithi, i-masonry, kunye neetayile ze-ceramic. Yenza ikhonkco elomeleleyo phakathi kodaka kunye ne-substrate, okukhokelela kwiipropati ezingcono zokubambelela kunye nokwandisa amandla okubambisana.
6. Ukuhambelana nezinye izongezo: I-HEMC ihambelana noluhlu olubanzi lwezinye izongezo ezisetyenziswa ngokuqhelekileyo kwimixube eyomileyo yodaka, njenge-air-entraining agents, i-plasticizers, kunye nokumisela i-accelerators. Oku kuvumela ukwakheka bhetyebhetye kunye nokwenza ngokwezifiso ukuhlangabezana neemfuno ezithile zokusebenza.

I-HEMC idlala indima ebalulekileyo ekuphuculeni ukusebenza komxube owomileyo ngodaka ngokuphucula ukusebenza, ukubambelela, ukugcinwa kwamanzi, kunye nomgangatho jikelele. Ukusetyenziswa kwayo kunceda ekuqinisekiseni ukufakwa ngempumelelo kunye nokusebenza kakuhle kwezinto ezahlukeneyo zokwakha ngelixa kugcinwa ukuhambelana kunye nokuqina kwizicelo ezigqityiweyo.
