I-Masonry yinto ebalulekileyo kunye nesisiseko sokwakha esele ikho kangangeenkulungwane. Kubandakanya ukusebenzisa izitena, ilitye, kunye nezinye izinto zokwakha izakhiwo ezomeleleyo kunye nezomeleleyo. Ukuqinisekisa umgangatho ophezulu we-masonry mortar, izongezo ezahlukahlukeneyo zisetyenziselwa ukwandisa amandla kunye nokusebenza kwayo. Esinye sezongezo yi-cellulose ether, eye yafunyaniswa ukuba iyasebenza ekuxubeni i-aggregate masonry mortars. Eli phepha lixoxa ngeempawu kunye noncedo lwe-cellulose ether exutywe udaka lwemasonry mortar.
I-cellulose ethers ithathwe kwimicu yezityalo kwaye idla ngokusetyenziswa kwintsimi yokwakha njengezongezo kwizinto zokwakha ezisekelwe kwisamente. Yenziwe kwi-cellulose yendalo eye yatshintshwa ngokwekhemikhali ukuphucula iimpawu zayo. I-cellulose ether i-polymer e-soluble yamanzi enokuthi yongezwe kwizigaba ezahlukeneyo zokulungiswa kodaka ukuphucula ukusebenza kodaka. Kukho iintlobo ezahlukeneyo ze-cellulose ethers, kuquka i-methylhydroxyethylcellulose (MHEC), i-ethylhydroxyethylcellulose (EHEC), kunye ne-hydroxyethylcellulose (HEC), phakathi kwabanye.
Ukusebenza kwe-cellulose ether exutywe udaka lwamasonry aggregate
Ukuphucula ukusebenza
Olunye uncedo oluphambili lokusebenzisa i-cellulose ethers kumxube we-masonry mortars kukuphucula ukusebenza. I-cellulose ethers isebenza njengezithambiso, ukunciphisa ukungqubana phakathi kodaka kunye nezinye izinto. Oku kwenza ukuba udaka lusasazeke lula, ukunciphisa ixesha lokwakha kunye nokwandisa imveliso. Ukongeza, i-cellulose ether inokunyusa ukuhambelana komxube, okwenza ukuhanjiswa kodaka kube lula kwaye kufana.
ukwandisa ukugcinwa kwamanzi
I-ether ye-cellulose yi-hydrophilic, ethetha ukuba inobudlelwane namanzi. Xa idityaniswe kudaka oluxutyiweyo lwemasonry, inokunyusa ukugcinwa kwamanzi kodaka. Oku kunceda ukugcina udaka lufumile ixesha elide, okubalulekileyo kwinkqubo yokunyanga. Ukunyangwa ngokufanelekileyo kuqinisekisa ukuba udaka lufikelela kumandla alo aphezulu, okwenza lube luhlala kwaye luhlala ixesha elide.
ukunciphisa ukucutheka
Olunye uncedo lokusebenzisa i-cellulose ethers kwi-mixed aggregate masonry mortars kukunciphisa ukucutheka. Ukucutheka kwenzeka xa udaka loma kwaye lulahlekelwe ngumswakama, lubangela ukuba lucutheke. Oku kunokukhokelela ekuqhekekeni kunye nezinye iziphene kwisakhiwo esigqityiweyo. I-cellulose ethers inceda ukunciphisa ubuninzi bamanzi aphuphumayo kwi-mortar, ngaloo ndlela inciphisa i-shrinkage kunye nokuphucula umgangatho opheleleyo weprojekthi egqityiweyo.
ukwandisa ukunamathela
Ukubambelela okulungileyo phakathi kweeyunithi zodaka kunye ne-masonry kubalulekile kwisakhiwo esomeleleyo kunye nesigxina. I-cellulose ethers iphucula ukunamathela komdaka ngokudibanisa kunye neengqungquthela zesamente. Oku kwandisa iipropati zokubambelela zodaka, okukhokelela kwisakhiwo esinamandla, esithembekileyo.
ukwandisa ukuguquguquka
Izakhiwo ezixubeneyo ze-masonry ezidibeneyo zisengozini yokuqhekeka ngenxa yezinto zangaphandle ezifana nokutshintsha kweqondo lokushisa, ukufuma kunye nezinye iimeko zokusingqongileyo. I-cellulose ether kwi-mixed aggregate masonry mortar inceda ukuphucula ukuguquguquka kodaka. Oku kwenza ukuba kungabi lula ukuphuka kwaye kunceda ukugcina imfezeko yesakhiwo seprojekthi.
ukuququmbela
Isishwankathelo, kukho izibonelelo ezininzi zokusebenzisa i-cellulose ethers kwimixube yodaka lwemasonry ehlanganisiweyo. Iphucula ukusebenza, iphucula ukugcinwa kwamanzi, inciphisa ukucutheka, inyusa ukunamathela kunye nokuphucula ukuguquguquka. Xa isetyenziswe ngokuchanekileyo, i-cellulose ethers inokuphucula umgangatho jikelele kunye nokuqina kwezakhiwo ezixubeneyo ze-masonry. Yinto ehambelana nokusingqongileyo kunye neyongezo eneendleko ezinokuthi zisetyenziswe kuluhlu lweeprojekthi zokwakha. Ke ngoko, iikontraka kunye nabakhi kufuneka bathathele ingqalelo ukusebenzisa i-cellulose ethers kwimixube yodaka lwamasonry aggregate.
