Redispersible polymer powder (RDP) ke tlatsetso ea bohlokoa linthong tsa sejoale-joale tsa kaho, haholo-holo ka likhomaretsi, seretse le lipolasetere.Ka ho ntlafatsa boleng ba 'mele le lik'hemik'hale tsa thepa ena, li-RDP li bapala karolo ea bohlokoa ho ntlafatseng ho tšoarella le ho sebetsa ha merero ea kaho.
Sebopeho le Mokhoa oa RDP
RDP e hlahisoa ka ho omisa emulsion ea thepa ea polymeric, hangata e thehiloeng ho vinyl acetate-ethylene (VAE), acrylic, kapa styrene-butadiene.Ts'ebetso ena e fetola emulsion hore e be phofo e ntle e ka qhalakantsoeng hape ka metsing, e tsosolosa ho hasana ha polymer ea pele.Ha e kenyelletsoa ho metsoako ea seretse se omeletseng, RDP e tsosolosa ha e kopana le metsi, e etsa filimi e ts'oanang le e tsitsitseng ka har'a matrix a khomarelang.
Ho Matlafatsa Khahlano ea Metsi
Tlhahiso ea Lifilimi: Ka holim'a metsi, likaroloana tsa RDP lia kopana ho etsa filimi ea polymer e tsoelang pele ho pholletsa le matrix a sekhomaretsi.Filimi ena e sebetsa e le tšitiso, haholo ho fokotsa porosity le metsi permeability ea sekhomaretsi.Filimi e thibela likanale tsa capillary, e thibela ho kenella ha metsi le ho ntlafatsa bokhoni ba sekhomaretsi ba ho thibela metsi ka kakaretso.
Thepa ea Hydrophobic: Mefuta e mengata ea RDP e kenyelletsa li-agent tsa hydrophobic kapa li-modifiers tse matlafatsang ho thibela metsi.Likarolo tsena tsa hydrophobic li fokotsa ho monya ha metsi ka sekhomaretsi, ho netefatsa ts'ebetso ea nako e telele esita le maemong a mongobo.
Tšebelisano e Ntlafetseng le ho Fetolana: RDP e ntlafatsa momahano ea ka hare ea sekhomaretsi, e ntlafatsa matla a eona a tlamahano le ho feto-fetoha ha maemo.Ho tenyetseha hona ho bohlokoa ho thibela ho hlaha ha mapetsong le likheo tse ka lumellang metsi ho phunyeletsa.Sekhomaretsi se ka amohelang katoloso ea mocheso le ho honyela ntle le ho peperana se boloka botšepehi ba sona le ho hanyetsa metsi ha nako e ntse e ea.
Ho Matlafatsa Boemo ba Boemo ba Leholimo
UV Stability: RDP formulations hangata e etselitsoe ho hanela ho senyeha ho tsoa maboneng a ultraviolet (UV).Filimi ea polymer e entsoeng ke RDP e tsitsitse UV, e sireletsa sekhomaretsi se ka tlase ho liphello tse kotsi tsa ho pepesehela letsatsi nako e telele.Botsitso bona bo tiisa hore sekhomaretsi se boloka matla a sona le elasticity esita le ka mor'a ho pepesehela letsatsi ka nako e telele.
Thermal Resistance: Lisebelisoa tsa kaho li tlas'a liphetoho tse feteletseng tsa mocheso, tse ka bakang ho atolosoa le ho fokotseha.Likhomaretsi tse fetotsoeng tsa RDP li bonts'a khanyetso e ntle ea mocheso, li boloka matla a tsona a tlamo le ho feto-fetoha ha maemo ho pholletsa le mefuta e mengata ea mocheso.Thepa ena e thibela sekhomaretsi hore se se ke sa senyeha maemong a leholimo a batang kapa ho ba bonolo haholo maemong a chesang, ka hona se matlafatsa ho hanyetsa boemo ba leholimo.
Resistance to Freeze-Thaw Cycles: Libakeng tse batang haholo, lisebelisoa li ba le linako tse pheta-phetoang tsa leqhoa, tse ka bakang kotsi haholo.Ho tenyetseha le momahano tse fanoeng ke RDP li thusa likhomaretsi ho mamella lipotoloho tsena ntle le ho lahleheloa ke bots'epehi.Filimi ea polymer e sebetsa joalo ka ntho e ts'oenyang, e fokotsang khatello ea maikutlo e bakoang ke leqhoa le ho qhibiliha.
Lisebelisoa tse Sebetsang
Exterior Insulation and Finish Systems (EIFS): RDP e sebelisoa haholo ho EIFS, moo ho hanyetsa metsi le boemo ba leholimo ho leng bohlokoa.Phofo ea polymer e etsa bonnete ba hore likarolo tsa sekhomaretsi lits'ebetsong tsena li ka hanela ho kenella ha mongobo le ho mamella maemo a leholimo a fapaneng, ho sireletsa sebopeho sa sebopeho le thepa ea ho kenella ka har'a sistimi.
Likhomaretsi tsa Lithaele le Li-Grouts: Lits'ebetsong tse kahare le kantle, likhomaretsi tsa lithaele le li-grouts tse fetotsoeng ka RDP li bonts'a ts'ebetso e phahameng.Li hanela ho kenella ha metsi le ho thibela lithaele hore li se ke tsa hlepha kapa tsa senyeha ka lebaka la boemo ba leholimo.Sena se bohlokoa haholo-holo libakeng tsa ka ntle moo lithaele li pepesetsoang pula, serame le letsatsi le tobileng.
Lokisa Metsi le Metsoako ea Patching: Bakeng sa tokiso ea konkreite le ho patch, RDP e ntlafatsa ho tšoarella ha lisebelisoa tsa tokiso.E etsa bonnete ba hore lisebelisoa tsena li tlamahane ka katleho ho konkreite e teng, ho fana ka tharollo e sa keneleng metsi le ea boemo ba leholimo e lelefatsang nako ea ho lokisoa.
Melemo ea Tikoloho le Moruo
Nako e Atolositsoeng ea Bophelo: Ka ho ntlafatsa ho hanyetsa metsi le boemo ba leholimo, RDP e eketsa nako ea bophelo ea likhomaretsi tsa kaho le meaho eo li sebelisoang ho eona. Sena se fokotsa tlhokahalo ea ho lokisoa khafetsa le ho nkeloa sebaka, e leng se lebisang ho theoeng ha litšenyehelo tsa tlhokomelo le tšebeliso ea lisebelisoa.
Matla a Matla: Lits'ebetsong tse kang EIFS, likhomaretsi tse ntlafalitsoeng tsa RDP li kenya letsoho ts'ebetsong e ntle ea ho kenya letsoho ka ho boloka botsitso ba sistimi ea ho kenya letsoho.Sena se ka lebisa tlhokomelong ea bohlokoa ea matla ho futhumatsang le meahong e pholileng, ho khothaletsa botsitso.
Litšila tse Fokotsoeng: Tšebeliso ea likhomaretsi tse tšoarellang nako e telele, tse mamellang boemo ba leholimo ho fokotsa litšila tsa kaho tse hlahisoang ke thepa e sa sebetseng kapa e senyehileng.Sena se kenya letsoho mekhoeng e tsitsitseng ea kaho le ho fokotsa tšusumetso ea tikoloho ea merero ea kaho.
Redispersible polymer powder ke tlatsetso e fetolang likhomaretsing tsa kaho, e fanang ka thepa ea bohlokoa ea ho hanyetsa metsi le boemo ba leholimo.Bokhoni ba eona ba ho theha filimi e sireletsang ea polymer, e kopantsoeng le litšobotsi tsa hydrophobic le ho feto-fetoha ha maemo, ho etsa hore likhomaretsi tse fetotsoeng tsa RDP li be matla khahlano le liqholotso tsa mongobo le maemo a leholimo.Ka ho kopanya RDP ho thepa ea kaho, lihahi le lienjineri li ka etsa bonnete ba hore meaho e tšoarella, e tšoarellang haholoanyane e hlomelloa hamolemo ho mamella khatello ea tikoloho.Sena ha se matlafatse ts'ebetso le ts'epahalo ea merero ea kaho feela empa hape se khothaletsa botsitso le ho boloka litšenyehelo indastering.
