Ubume be-Cellulose Ethers kwi-Cement Mortar

Indlela ye-cellulose ethers kwi-cement mortar ibandakanya intsebenziswano eyahlukeneyo kunye neenkqubo ezifaka isandla ekusebenzeni ngokubanzi kunye neempawu zodaka. Nantsi isishwankathelo seendlela ezibandakanyekayo:

1. Ukugcinwa kwamanzi: I-ethers ye-cellulose inamaqela e-hydrophilic athatha ngokukhawuleza kwaye agcine amanzi ngaphakathi kwe-matrix yodaka. Oku kugcinwa kwamanzi ixesha elide kunceda ukugcina udaka lusebenza ixesha elide, ukuthintela ukomisa kwangaphambi kwexesha kunye nokuqinisekisa ukuchithwa okufanayo kwamasuntswana e-samente.
2. Ukulawulwa kokuHlulwa: I-ethers ye-cellulose inokulibazisa ukuhanjiswa kwamasuntswana e-samente ngokwenza ifilimu ekhuselayo ejikeleze kubo. Oku kulibaziseka kwe-hydration kwandisa ixesha elivulekileyo lodaka, ukuvumela ixesha elaneleyo lokufaka isicelo, ukulungiswa kunye nokugqiba.
3. Ukuphuculwa kwe-Dispersion: I-cellulose ethers isebenza njenge-dispersants, ikhuthaza ukusabalalisa okufanayo kweengqungquthela zesamente kumxube wodaka. Oku kwandisa i-homogeneity ngokubanzi kunye nokuhambelana kodaka, okukhokelela ekusebenzeni okungcono kunye nokusebenza.
4. I-Adhesion ephuculweyo: I-cellulose ethers iphucula ukudibanisa kwe-cement mortar kwi-substrate surfaces ngokwenza i-cohesive bond phakathi kwamaqhekeza omdaka kunye ne-substrate. Oku kunceda ukuthintela ukungaphumeleli kwebhondi kunye nokuqinisekisa ukubambelela okuthembekileyo, naphantsi kweemeko ezinzima.
5. Ukuqina kunye nokuBophelela: Ii-ether ze-cellulose zisebenza njengezinto ezityebisayo kunye nezibophelelo kudaka lwesamente, zikhulisa i-viscosity kunye nokudibana kwayo. Oku kunika ukusebenza ngcono kwaye kunciphisa umngcipheko wokuthoba okanye ukuthoba ngexesha lokufaka isicelo, ngakumbi kufakelo oluthe nkqo kunye noluphezulu.
6. I-Crack Prevention: Ngokuphucula ukubambisana kunye nokuguquguquka komdaka, i-cellulose ethers inceda ukusabalalisa uxinzelelo ngakumbi kwi-matrix, ukunciphisa amathuba okuqhekeka kwe-shrinkage kunye neziphene zomhlaba. Oku kwandisa ukuqina kunye nokusebenza kodaka.
7. Ukungena komoya: I-cellulose ethers inokuququzelela ukungena komoya okulawulwayo kwidaka le-samente, ekhokelela ekuphuculeni ukuxhathisa ukunyibilika, ukunciphisa ukufunxa kwamanzi, kunye nokuqina okuphuculweyo. Amaqamza omoya avalelekileyo asebenza njengesithinteli ngokuchasene nokuguquguquka koxinzelelo lwangaphakathi, ukunciphisa umngcipheko womonakalo ngenxa yemijikelo yokunyibilika komkhenkce.
8. Ukuhambelana kunye neZongezo: I-cellulose ethers iyahambelana noluhlu olubanzi lwezongezo eziqhelekileyo ezisetyenziselwa ukwakhiwa kodaka lwesamente, ezifana nezizaliso zamaminerali, i-plasticizers, kunye ne-air-entraining agents. Zinokudityaniswa ngokulula kwimixube yodaka ukufezekisa iimfuno ezithile zokusebenza ngaphandle kokuchaphazela kakubi ezinye iipropathi.

iindlela ze-cellulose ethers kwi-cement mortar zibandakanya ukuhlanganiswa kokugcinwa kwamanzi, ukulawulwa kwe-hydration, ukusasazwa okuphuculweyo, ukunyusa ukunamathela, ukuqina kunye nokubopha, ukuthintela ukuqhekeka, ukungena emoyeni, kunye nokuhambelana nezongezo. Ezi ndlela zisebenza ngokubambisana ukwandisa ukusebenza, ukusebenza, kunye nokuqina kodaka lwesamente kwizicelo ezahlukeneyo zokwakha.
