Ho Eketsa Matla a ho Khomarela: Kamoo Phofo ea Polymer e Nchafalitsoeng (RDP) e Fetolang Li-mortar tse Kopantsoeng

Hobaneng Matla a ho Khomarela a le Bohlokoa ho Li-mortar tse Kopantsoeng

Ho khomarela ke motheo oa lithaele tse kopanyang tse sebetsang hantle. Ebang ke ho tiisa lithaele, ho lokisa konkreite, kapa ho kenya litsamaiso tsa ho kenya mocheso, sethaele se tlameha ho:

• Hanela khatello ea ho kuta le ho hatelloaho tsoa liphetohong tsa tikoloho kapa meroalo ea mechini.
• Boloka kutlwano ea nako e teleleho sa tsotellehe ho pepesehela mongobo, liphetoho tsa mocheso, kapa ho thothomela.
• Thibela ho qhaqhoa ha lerapakeng tsa di-substrate (mohlala, konkreite, lehong, kapa gypsum).

Hangata disetere tse thehilweng samenteng tsa setso ha di na ho tenyetseha le ho kgomarela tlasa maemo a feto-fetohang. Mona ke moo RDP e kenellang e le mohlodi wa tshebetso.

Kamoo RDP e Ntlafatsang Khomarelo ka Li-mortar

Phofo ea Polymer e qhalakantsoeng hape ke copolymer e omisitsoeng ka spray (mohlala, vinyl acetate-ethylene) e kopanyang hape ha e tsoakoa le metsi. Ka har'a li-bonding mortars, RDP e sebetsa ka:

1. Ho Theha Filimi ea Polymer: Ha seretse se ntse se fola, RDP e theha marang-rang a tenyetsehang, a kenellang a kopanyang dikarolwana tsa samente le di-aggregate. Filimi ena e kopanya dikgeo pakeng tsa seretse le substrate, e ntlafatsa kgomarelo ya mechini.
2. Ho Fokotsa Bobebe: Ho fapana le matrices e thata ea samente, RDP e eketsa ho tenyetseha, e leng se lumellang li-mortar ho monya khatello ntle le ho petsoha.
3. Ho Ntlafatsa ho Koloba ha Metsi: RDP e ntlafatsa bokgoni ba seretse ba ho "tshwara" dibaka tse nang le masoba kapa tse boreledi, esita le maemong a thata.

Melemo ea Bohlokoa ea RDP ho Li-Bonding Mortars

1. Matla a Tlamo e Phahameng: Li-mortar tse fetotsoeng ke RDP li fihlella ho fihlela hoHo khomarela ho matla ka makhetlo a 2ha ho bapisoa le metswako e sa fetoloang, ho latela teko ea ASTM C1583.
2. Khanyetso ea Mapetso: Filimi ea polymer e fokotsa mapetso a manyenyane a bakoang ke ho fokotseha kapa katoloso ea mocheso.
3. Khanyetso ea Metsi: RDP e fokotsa ho monyela metsi, e sireletsa tlamo hore e se ke ea senyeha ke mongobo.
4. Ho feto-fetoha ha maemo: E sebetsa hantle hodima di-substrate tse fapaneng, ho kenyeletswa konkreite, di-ceramics, le diboto tsa ho kenya mocheso tsa EPS.
5. Bokhoni ba ho sebetsa: RDP e ntlafatsa ho ata ha seretse, e netefatsa hore ts'ebeliso e lekana le ho fokotsa nako ea basebetsi.

RDP e Sebetsa: Likopo tsa Lefatše la Sebele

• Likhomaretsi tsa Lithaele: RDP e netefatsa hore lithaele li lula li hokahane ka thata libakeng tse metsi (mohlala, matloana a ho hlapela, matamo a ho sesa) le libakeng tse nang le sephethephethe se seholo.
• Mekhoa ea ho Thibela Leboteng ea Kantle: E ntlafatsa ho khomarela ha li-base coat ho liphanele tsa insulation, e thibela ho hloleha ha sistimi.
• Litokiso tsa Konkreite: E tsosolosa maqhama a sebopeho meralong ya motheo e tsofetseng ntle le ho kgaola.
• Metsoako ea ho Lekanya Mokato: E theha tlamo e se nang sekoli pakeng tsa libaka tsa khale le tse ncha.

Tšebelisano-'moho le Cellulose Ethers

Bakeng sa di-formulator tse sebedisang di-ether tsa cellulose (mohlala, HPMC, MHEC), RDP e sebetsa e le sehlomathiso se tlatsetsang. Leha di-ether tsa cellulose di fana ka ho boloka metsi le ho a tiisa, RDP e eketsa:

• Matlafatso ea ho khomarelabakeng sa lits'ebetso tsa bohlokoa tse otlolohileng kapa tse holim'a hlooho.
• Ho tenyetsehaho amohela motsamao oa substrate.
• Ho tšoarellamaemong a leholimo a thata.

Ho kopanya lintho tse tlatsetsang ka bobeli ho hlahisa li-mortar tse fihlelang maemo a holimo bakeng sa likhomaretsi tse tšesaane, li-render le litsamaiso tsa tokiso.
