Ama-ether e-cellulose okwakha ngobumba kanye nodaka lokuplasta

Ukusetshenziswa kwama-cellulose ethers ku-masonry kanye ne-plastering mortar kuyintuthuko ebalulekile kubuchwepheshe bezinto zokwakha zesimanje. Akugcini nje ngokuthuthukisa ukusebenza kokwakhiwa kanye nokusebenza kokubopha kwe-mortar, kodwa futhi kuthuthukisa ukugcinwa kwamanzi, ukusebenza kahle kanye nezakhiwo zayo zokulwa nokuwa, ngaleyo ndlela kuthuthukisa kakhulu ukusebenza kahle kokwakhiwa kanye nekhwalithi yesakhiwo.

1. Incazelo kanye nezinhlobo zama-cellulose ethers

Ama-cellulose ether ayisigaba samakhemikhali e-polymer angewona ama-ionic noma ama-ionic akhiwe ukuguqulwa kwamakhemikhali kwe-cellulose yemvelo. Anezakhiwo ezinhle zokuncibilika kwamanzi kanye nokwakha ifilimu futhi avame ukusetshenziswa ekwakheni, kwezokwelapha, ekudleni, kumakhemikhali ansuku zonke nakwamanye amasimu. Ekwakheni i-mortar, ama-cellulose ether asetshenziswa kakhulu yilawa:

I-Hydroxypropyl methylcellulose (HPMC)

I-Methyl hydroxyethyl cellulose (MHEC)

I-Hydroxyethyl cellulose (HEC)

I-HPMC isetshenziswa kakhulu ekubumbeni nasekuplasteni ngenxa yokugcina kwayo amanzi kahle, ukuzinza okuphezulu kokushisa kanye nokusebenza kahle kokwakha.

2. Indima ye-cellulose ether ku-masonry mortar

Udaka lwamatshe lusetshenziselwa ukuxhuma izinto zokwakha ezifana nezitini namatshe. Ludinga ukuthi udaka lube nokunamathela okuhle kanye nokugcinwa kwamanzi ukuze kuvinjelwe umswakama ukuthi ungamuncwa ngokushesha yizitini ngesikhathi sokwakha, ngaleyo ndlela kuthinte umphumela wokubopha.

Thuthukisa ukugcinwa kwamanzi

I-cellulose ether inamandla okugcina amanzi futhi ingakha ifilimu encane ku-mortar ukuze ivale umswakama futhi ivimbele umswakama ukuthi ungamuncwa ngokushesha ngesikhathi senqubo yokwakhiwa kwe-marshmallow. Lokhu kusiza usimende ukuthi umanzise ngokugcwele, ngaleyo ndlela kuthuthukiswe amandla nokunamathela komotar.

Thuthukisa ukusebenza kokwakha

Ngemva kokufaka i-cellulose ether, udoti wokwakha uthanjiswa kakhulu futhi ubushelelezi, unomuzwa omuhle wokwakha, futhi unciphisa izinkinga zekhwalithi njengokugoba kanye nokuqhekeka.

Thuthukisa ukusebenza kokubopha

Ukugcinwa kwamanzi okuhle kanye nokuqina kwenza udaka lube lula ukunamathela ebusweni bezitini namatshe, kungabi lula ukuwa, futhi kuthuthukise ukusebenza kahle kokwakha ngamatshe.

3. Indima ye-cellulose ether ku-plaster mortar

Udaka lwe-plaster lusetshenziswa kakhulu ekulinganiseni nasekuhlobiseni izindonga zesakhiwo, futhi lunezidingo eziphezulu zokusebenza kokwakhiwa kanye nekhwalithi yobuso.

Lawula izinga lokumuncwa kwesimende

Ku-plaster mortar, i-cellulose ether ingalibazisa ukulahleka kwamanzi futhi yenze i-simende igcwale kakhulu, ngaleyo ndlela yandise amandla futhi inciphise ukuqhekeka.

Vimbela ukugoba futhi uthuthukise ukusebenza kokwakhiwa kwe-facade

Ngenxa yomphumela omuhle wokujiya kwe-cellulose ether, ingavimbela udoti we-plaster ukuthi ungagugi lapho wakhiwe phezu kwendawo eqondile, okuthuthukisa ukusebenza kahle.

Thuthukisa ukusebenza kahle

I-cellulose ether yenza kube lula ukuyishelela nokuyiqeda i-plaster mortar, ithuthukisa ukusebenza kahle kokwakhiwa kanye nekhwalithi yendawo, futhi yenza indawo ibe bushelelezi futhi ibe bushelelezi kakhudlwana.

Ukumelana okuthuthukisiwe kokuqhekeka

Ukuthuthukiswa kokugcinwa kwamanzi kanye nokuguquguquka kusiza ukuthuthukisa ukumelana nokuqhekeka kwesendlalelo seplasta futhi kunciphise ingozi yokuqhekeka nokuwa.

4. Izici ezithinta ukusebenza kwe-cellulose ether

Ukusebenza kwe-cellulose ether kuhlobene eduze nesakhiwo sayo samakhemikhali, izinga lokushintshaniswa (DS), i-viscosity, usayizi wezinhlayiya kanye nezinye izici. Ngokuqondile:

Izinga lokushintshana:kuthinta izinga lokuncibilika kwamanzi kanye nezinga lokuncibilika. Ngokuvamile, izinga lokushintshanisa phakathi kuka-1.4 no-1.9 lifaneleka kakhulu ngezinjongo zokwakha.

Ukujiya:inquma umphumela wayo wokujiya ku-mortar, futhi ububanzi be-viscosity obusetshenziswa kakhulu bungu-400 ~ 100,000 mPa·s.

Usayizi wezinhlayiya:kuthinta ukuhlakazeka kwayo kanye nesivinini sokuncibilika. Uma usayizi wezinhlayiya uncane, kulapho incibilika khona ngokushesha.

5. Isilinganiso kanye nezinyathelo zokuphepha ezisebenzayo

Ku-mortar yobumba kanye ne-plastering, inani lokwengeza le-cellulose ether ngokuvamile lilawulwa ku-0.1% ~ 0.4% (ngokusekelwe kubuningi besimende noma izinto ezisebenzisa ubumba). Uma usebenzisa, kufanele unake:

Hlanganisa ngokuphelele ngokulinganayo ukuze ugweme ukuhlangana;

Nakani izinga lokushisa lokuncibilika nesikhathi se-cellulose ether;

Ukusebenza kwama-ether e-cellulose emikhiqizo ehlukene kanye namazinga e-viscosity kuhluke kakhulu, futhi isilinganiso esihle kakhulu sidinga ukunqunywa ngokuhlolwa.

Njengesengezo esisebenza kahle kakhulu,i-cellulose etherKuthuthukise kakhulu ukusebenza okuphelele kodaka lokubumba nokufaka iplasta, okwenza ukwakhiwa kube ngcono kakhulu futhi ikhwalithi ithembeke kakhudlwana. Ngokuthuthuka kwezinto zokwakha eziluhlaza, isidingo sama-ether e-cellulose anobungani nemvelo futhi asebenza kahle sizoqhubeka nokukhula. Ezisetshenzisweni ezisebenzayo, ukukhetha uhlobo olufanele kanye nemodeli ye-cellulose ether nokulawula ngokwesayensi umthamo wayo kuyisihluthulelo sokuqinisekisa ukuthi ukusebenza kodaka kuyahlangabezana nezindinganiso.
