Ama-cellulose ethers avame ukusetshenziswa njengezithasiselo odakeni olususelwa ku-gypsum ukuze kuthuthukiswe izakhiwo nezici zokusebenza ezahlukahlukene.Okulandelayo ezinye izinhlelo zokusebenza ezithile ze-cellulose ethers ku-gypsum mortar:
Ukugcinwa kwamanzi:
Ama-cellulose ether angama-hydrophilic polymers, okusho ukuthi anokuhlobana okuphezulu kwamanzi.Uma zengezwe odakeni lukakhonkolo, zigcina kahle umswakama futhi zivimbele ingxube ukuthi yome ngokushesha.Lokhu kubalulekile ukuqinisekisa ukuthi ukhonkolo unesikhathi esanele sokukhipha amanzi ngendlela efanele futhi uthuthukise ukusebenza kahle.
Ukucutshungulwa nokusebenziseka kalula:
Izici zokugcina amanzi ze-cellulose ethers zisiza ukuthuthukisa ukusebenza kwe-gypsum mortar.Udaka luba lula ukuxutshwa, ukusabalalisa nokusetshenziswa, okwenza inqubo yokwakha ibe bushelelezi futhi isebenze kahle.
Yehlisa ukushwabana:
Ama-cellulose ethers asiza ukulawula ukushwabana okomisa kwezinsimbi ze-gypsum.Ngokugcina okuqukethwe kwamanzi okwanele ngesikhathi sokusetha nokomisa, ama-cellulose ethers asiza ukunciphisa ukuqhekeka kokuncipha futhi aqinisekise ukuzinza kwe-dimensional yomkhiqizo oqediwe.
Thuthukisa ukunamathela:
Ama-cellulose ether athuthukisa ukunamathela kodaka lwe-gypsum ezinhlobonhlobo zama-substrates, okuhlanganisa izindonga nophahla.Lokhu kubaluleke kakhulu ekusetshenzisweni okunjengokuplasta nokunikezela, lapho isibopho esiqinile sibalulekile ekuqina nokuphila isikhathi eside kwendawo eqediwe.
Ukumelana nokuqhekeka:
Ukwengeza i-cellulose ether kungathuthukisa ukumelana nokuqhekeka kodaka.Lokhu kunenzuzo ikakhulukazi ezindaweni lapho ukunyakaza kwesakhiwo kujwayele ukwenzeka noma lapho udaka lungagcizelelwa, njengenhlanganisela ehlangene kanye nezingqimba ze-putty.
I-Anti-sag:
Ekusetshenzisweni okume mpo, okufana namaplasta odongeni, ama-cellulose ethers asebenza njengokujiya, anciphisa ukucwila nokuwa kodaka.Lesi sici sisiza ukugcina ukujiya okufanayo ezindaweni eziqondile, sithuthukisa ubuhle nokusebenza kohlelo lokusebenza lokugcina.
Thuthukisa ukubumbana:
Ama-cellulose ethers afaka isandla ekuhlanganisweni kwengxube yodaka, ukuthuthukisa ubuqotho bayo besakhiwo jikelele.Lokhu kubalulekile ezinhlelweni lapho udaka ludinga ukumelana namandla angaphandle noma izingcindezi.
Ukuzinza kweqhwa:
Ama-cellulose ether angathuthukisa ukuzinza kokuncibilika kwe-gypsum, awenze amelane kakhulu nomonakalo endaweni enamazinga okushisa ashintshashintshayo.Lokhu kubaluleke kakhulu ezinhlelweni zokwakha ezivezwe esimweni sezulu esibi.
Nweba isikhathi sokusetha:
Ukusebenzisa ama-cellulose ether kunganweba isikhathi sokumisa udaka lukakhonkolo, okuvumela ukuguquguquka okukhulu ekufakweni nasekuqedeni.Lokhu kuwusizo ikakhulukazi ezimeni lapho amahora okusebenza amade adingeka khona.
Izici ezithuthukisiwe ze-rheological:
Ama-cellulose ethers afaka isandla kuzakhiwo ze-rheological zodaka, ezithonya ukugeleza kwawo kanye nezici zokuguqulwa.Lokhu kusiza ukufeza ukuvumelana okudingekayo nokusebenza kohlelo lokusebenza.
Kubalulekile ukuqaphela ukuthi uhlobo oluthile kanye nesilinganiso se-cellulose ether esetshenzisiwe kanye nokwakhiwa kwe-gypsum mortar kufanele kucatshangelwe ngokucophelela ukuze kuzuzwe imiphumela oyifunayo kuhlelo lokusebenza olunikeziwe.Abakhiqizi bavamise ukwenza ukuhlola nokuthuthukisa ukuze bathole okuqukethwe kwe-cellulose ether ephumelela kakhulu emikhiqizweni yabo ethile kanye nokusetshenziswa okuhlosiwe.
