Indima esebenzayo yeCellulose ether kwiDry Mix Mortar

I-cellulose ethers, efana ne-hydroxypropyl methyl cellulose (HPMC), i-hydroxyethyl cellulose (HEC), kunye ne-carboxymethyl cellulose (CMC), idlala iindima ezininzi zokusebenza kwimixube eyomileyo yodaka, igalelo ekusebenzeni ngokubanzi kunye nokusebenza kodaka. Nazi ezinye iindima eziphambili zokusebenza ze-cellulose ethers kudaka lomxube owomileyo:

1. Ukugcinwa kwamanzi: Ii-ether ze-cellulose zineempawu ezibalaseleyo zokugcina amanzi, oku kuthetha ukuba zinokufunxa kwaye zigcine amanzi ngaphakathi kwe-matrix yodaka. Oku kugcinwa kwamanzi ixesha elide kunceda ukugcina udaka lusebenza ixesha elide, luvumela ixesha elaneleyo lokufaka isicelo, ukusasazeka, kunye nokugqiba.
2. Ukuphuculwa kokuSebenza: Amanzi agcinwe yi-cellulose ethers anegalelo kwiplastiki kunye nokusebenza kodaka. Ikhusela ukomiswa kwangaphambi kwexesha kunye nokuqina komxube, okwenza kube lula ukuphatha, ukusasazeka, kunye ne-trowel. Oku kwandisa ukukhululeka kwesicelo kunye nokuqinisekisa ukugubungela okufanayo kwi-substrate surfaces.
3. I-Adhesion eyandisiweyo: I-cellulose ethers iphucula ukunamathela kodaka lomxube owomileyo kwii-substrates ezahlukeneyo, kubandakanywa ikhonkrithi, i-masonry, kunye neetayile ze-ceramic. Zisebenza njengama-thickeners kunye nezibophelelo, zenza i-cohesive bond phakathi kwamasuntswana odaka kunye ne-substrate surfaces. Oku kukhuthaza ukunamathela okungcono kwaye kunciphisa umngcipheko wokungaphumeleli kwebhondi.
4. Ukunciphisa i-Sagging kunye ne-Slumping: Ngokunika i-viscosity kunye nokubambisana kwi-mortar, i-cellulose ethers inceda ukukhusela okanye ukudilika kwezinto xa zisetyenziswe ngokuthe nkqo okanye ngaphezulu. Oku kuqinisekisa ukuba udaka lugcina imilo kunye nobukhulu ngaphandle kokuguqulwa okugqithisileyo ngexesha lokusetyenziswa kunye nokunyanga.
5. Ixesha lokuvula eliphuculweyo: Ixesha lokuvula libhekisa kwixesha apho udaka luhlala lusebenza emva kokuxuba ngaphambi kokuba luqalise ukuseta. I-cellulose ethers yandisa ixesha elivulekileyo lodaka lomxube owomileyo ngokulibazisa ukuqala kwe-hydration kunye nokuqina. Oku kuvumela ixesha elaneleyo lokufaka isicelo, ukulungiswa, kunye nokugqitywa kokugqibela ngaphandle kokunciphisa amandla ebhondi.
6. I-Crack Resistance: I-Cellulose ethers inokunyusa ukuxhathisa ukuqhekeka kodaka lomxube owomileyo ngokuphucula ukuhambelana kwayo kunye nokuguquguquka. Banceda ekusasazeni uxinzelelo ngakumbi ngokulinganayo kuyo yonke i-matrix yodaka, ukunciphisa ukubakho kokuqhekeka kweentanda, ukuhlanya, kunye neziphene ezingaphezulu.
7. Ukungeniswa komoya oLawulwayo: I-ethers ye-cellulose inokuququzelela ukungena komoya okulawulwayo kwimixube eyomileyo yodaka. Amaqamza omoya avalelekileyo aphucula ukuxhathisa ukunyibilika komkhenkce, anciphise ukufunxwa kwamanzi, kwaye aphucule ukuqina kodaka.
8. Ukuhambelana kunye neZongezo: I-ethers ye-cellulose iyahambelana noluhlu olubanzi lwezongezo ezisetyenziswa ngokuqhelekileyo kwimixube eyomileyo yokuxutywa kodaka, njengama-fillers amaminerali, i-plasticizers, kunye ne-air-entraining agents. Zinokudityaniswa ngokulula kwimixube yodaka ukufezekisa iimfuno ezithile zokusebenza ngaphandle kokuchaphazela kakubi ezinye iipropathi.

I-cellulose ethers idlala indima ebalulekileyo ekwandiseni ukusebenza, ukusebenza, kunye nokuqina kodaka lomxube owomileyo, luzenza izongezo eziyimfuneko kwizicelo zolwakhiwo lwangoku.
