Cellulose Ether Properties of Mixed Aggregate Masonry Mortar

Masonry ke karolo ea bohlokoa le ea bohlokoa ea kaho e bileng teng ka lilemo tse makholo. E akarelletsa ho sebelisa litene, majoe le lintho tse ling ho etsa mehaho e tšoarellang le e matla. Ho netefatsa boleng bo phahameng ba seretse sa masonry, li-additives tse fapa-fapaneng li sebelisoa ho eketsa matla le ho sebetsa ha eona. E 'ngoe ea litlatsetso tse joalo ke cellulose ether, e fumanoeng e sebetsa ho tsoaka lirekere tse kopaneng tsa masonry. Pampiri ena e bua ka thepa le melemo ea cellulose ether e kopantsoeng le seretse sa masonry.

Li-cellulose ethers li tsoa ho likhoele tsa limela 'me hangata li sebelisoa tšimong ea kaho e le li-additives ho thepa ea mohaho e thehiloeng ho samente. E entsoe ka selulose ea tlhaho e fetotsoeng ka lik'hemik'hale ho ntlafatsa thepa ea eona. Cellulose ether ke polymer e qhibilihang ka metsing e ka ekeletsoang ka mekhahlelo e fapaneng ea ho lokisa seretse ho ntlafatsa ts'ebetso ea seretse. Ho na le mefuta e fapaneng ea li-cellulose ethers, ho kenyelletsa methylhydroxyethylcellulose (MHEC), ethylhydroxyethylcellulose (EHEC), le hydroxyethylcellulose (HEC), har'a tse ling.

Ts'ebetso ea seretse sa cellulose ether e kopaneng ea masonry

Ntlafatsa ts'ebetso

E 'ngoe ea melemo ea mantlha ea ho sebelisa li-ethers tsa cellulose ka har'a lirekere tse kopaneng tsa masonry ke ts'ebetso e ntlafetseng. Cellulose ethers e sebetsa joalo ka mafura, e fokotsang khohlano lipakeng tsa seretse le lisebelisoa tse ling. Sena se etsa hore seretse se hasane habonolo, ho fokotsa nako ea kaho le ho eketsa tlhahiso. Ho phaella moo, cellulose ether e ka eketsa ho tsitsisa ha motsoako, ho etsa hore kabo ea seretse e be bonolo le ho feta.

eketsa ho boloka metsi

Cellulose ether ke hydrophilic, ho bolelang hore e na le kamano ea metsi. Ha e eketsoa ho seretse se kopaneng sa masonry, se ka eketsa ho bolokoa ha metsi a seretse. Sena se thusa ho boloka seretse se le mongobo nako e telele, e leng sa bohlokoa bakeng sa mokhoa oa ho folisa. Pheko e nepahetseng e etsa bonnete ba hore seretse se fihlella matla a sona a phahameng, se etsa hore se tšoarelle le ho tšoarella nako e telele.

fokotsa ho ruruha

Molemo o mong oa ho sebelisa li-cellulose ethers ka har'a seretse se kopantsoeng sa masonry ke ho fokotseha ho fokolang. Shrinkage e etsahala ha seretse se omella mme se lahleheloa ke mongobo, se etsa hore se fokotsehe. Sena se ka lebisa ho mapetsong le liphoso tse ling mohahong o felileng. Li-cellulose ethers li thusa ho fokotsa bongata ba metsi a fetohang mouoane ka har'a seretse, kahoo ho fokotsa ho fokotseha le ho ntlafatsa boleng ba kakaretso ea morero o felileng.

ntlafatsa ho khomarela

Ho khomarela hantle pakeng tsa seretse le lihlopha tsa masonry ho bohlokoa bakeng sa mohaho o matla le o tšoarellang. Li-cellulose ethers li ntlafatsa ho khomarela seretse ka ho hokahanya le likaroloana tsa samente. Sena se ntlafatsa thepa ea sekhomaretsi ea seretse, e leng se etsang hore ho be le mohaho o matla, o ka tšeptjoang haholoanyane.

eketsa ho feto-fetoha ha maemo

Mehaho e kopaneng ea masonry e ka senyeha habonolo ka lebaka la mabaka a kantle joalo ka liphetoho tsa mocheso, mongobo le maemo a mang a tikoloho. Ether ea cellulose ka har'a seretse se kopaneng sa masonry se thusa ho ntlafatsa ho fetoha ha seretse. Sena se etsa hore ho se be bonolo ho senya le ho thusa ho boloka botšepehi ba moralo oa morero.

ha re phethela

Ka kakaretso, ho na le melemo e mengata ea ho sebelisa li-ether tsa cellulose ka har'a lirekere tse kopaneng tsa masonry. E ntlafatsa ts'ebetso, e ntlafatsa ho boloka metsi, e fokotsa ho fokotseha, e eketsa ho khomarela le ho ntlafatsa ho tenyetseha. Ha li sebelisoa ka nepo, li-cellulose ethers li ka ntlafatsa boleng ba kakaretso le ho tšoarella ha meaho e kopaneng ea masonry. Ke tlatsetso e baballang tikoloho le e bolokang chelete e ngata e ka sebelisoang mefuteng e mengata ea merero ea kaho. Ka hona, likonteraka le lihahi li lokela ho nahana ka ho sebelisa li-cellulose ethers ka har'a seretse se kopaneng sa masonry.
