Ho matlafatsa matla a maqhama a lithaele ho bohlokoa ho netefatsa botsitso le ho tšoarella ha lithaele. Tabeng ena, Redispersible Polymer Powder (RDP), e le tlatsetso ea bohlokoa, e phetha karolo ea bohlokoa.
1. Litšobotsi tsa motheo tsa phofo ea latex e ka sebelisoang hape
RDP ke phofo e fetisetsoang hape e hlahisoang ka emulsion ea polymer ka mokhoa oa ho omisa. Ha RDP e kopantsoe le metsi, e qhaqhoa hape ho etsa emulsion, e khutlisetsa litšobotsi tsa eona tsa pele. Thepa ena e etsa RDP phetoho ea bohlokoa bakeng sa likhomaretsi tsa lithaele.
2. Mokhoa oa ho ntlafatsa matla a tlamahano
2.1 Eketsa ho feto-fetoha ha maemo le ho hanyetsa crack
Ho eketsoa ha RDP ho ka eketsa ho feto-fetoha ha maemo le ho hanyetsa mapheo a likhomaretsi tsa lithaele. Filimi ea polymer e entsoeng e khona ho monya le ho thibela khatello ea maikutlo ka ntle le ho fokotsa mapetsong a bakoang ke ho honyela ha substrate kapa katoloso ea mocheso le ho honyela. Ho feto-fetoha ha maemo ho thusa lithaele hore li lule li le matla tlas'a maemo a fapaneng a khatello ea maikutlo, kahoo li eketsa matla a tlamahano ka kakaretso.
2.2 Ntlafatsa tack e metsi le nako ea ho bula
RDP e ka ntlafatsa mokelikeli o metsi oa likhomaretsi tsa lithaele tsa ceramic, e leng ho lumellang hore ho be le sekhomaretsi sa pele pakeng tsa lithaelese tsa ceramic le li-substrates nakong ea kaho. Ka nako e ts'oanang, RDP e eketsa nako ea ho bula li-adhesives tsa lithaele, ke hore, nako e sebetsang ho tloha ho kopo ho isa ho ho beha lithaele. Sena se fa basebetsi nako e lekaneng ea ho etsa liphetoho le ho beha maemo, ho netefatsa boleng ba ho peista.
2.3 Eketsa matla a momahano
RDP e eketsa haholo matla a kopantsoeng a sekhomaretsi sa lithaele ka ho etsa mohaho oa marang-rang a mararo ka hare ho oona. Sebopeho sena sa mesh se omella ho theha marang-rang a matla a polymer a eketsang matla a kakaretso a sekhomaretsi, kahoo a ntlafatsa ho khomarela lithaele.
3. Lintho tse susumetsang
3.1 Ho eketsa chelete ea RDP
Palo ea RDP e ekelitsoeng e ama ka kotloloho ts'ebetso ea sekhomaretsi sa lithaele. Ho eketsa chelete e lekaneng ea RDP ho ka ntlafatsa haholo matla a tlamahano, empa ho eketsoa ho feteletseng ho ka lebisa litšenyehelong tse eketsehileng le ho fokotsa ts'ebetso ea kaho. Ka hona, moralo oa tlhahiso o hloka ho ntlafatsoa ho latela litlhoko tse khethehileng.
3.2 Mefuta ea RDP
Mefuta e fapaneng ea RDP e na le litšobotsi tse fapaneng tsa ts'ebetso. Li-RDP tse sebelisoang ka tloaelo li kenyelletsa vinyl acetate-ethylene copolymer (VAE) le vinyl acetate-ethylene-vinyl chloride (VAE-VeoVa), eo e 'ngoe le e' ngoe e nang le melemo ea ho ntlafatsa ho feto-fetoha ha maemo, ho hanyetsa metsi le matla a ho kopanya. Ho bohlokoa ho khetha mofuta o nepahetseng oa RDP ho fumana litholoana tse nepahetseng.
4. Mehlala ea tšebeliso
Lits'ebetsong tse sebetsang, RDP e sebelisitsoe haholo bakeng sa phetoho ea likhomaretsi tsa lithaele tsa ceramic. Ka mohlala, libakeng tse nang le mongobo o mongata joalo ka kichineng le likamoreng tsa ho hlapela, likhomaretsi tsa lithaele tse kentsoeng ka RDP li bonts'a ho hanyetsa metsi ho betere le matla a tlamahano. Ho phaella moo, litsing tsa ho futhumatsa fatše, moo mocheso o fetohang khafetsa, li-adhesive tsa lithaele tse matlafalitsoeng tsa RDP li ka fana ka ho hanyetsa mocheso o motle le botsitso.
5. Mekhoa ea ntlafatso ea nako e tlang
Ka tsoelopele e tsoelang pele ea thekenoloji ea thepa ea moaho, menyetla ea ts'ebeliso ea RDP e tla ba kholoanyane. Litaelo tsa lipatlisiso tsa nako e tlang li ka kenyelletsa ho theha li-RDP tse ncha ho ntlafatsa ts'ebetso ea likhomaretsi tsa lithaele, hammoho le ho ntlafatsa moralo oa foromo ho fokotsa litšenyehelo le ho ntlafatsa ts'ebetso ea kaho. Ho feta moo, lipatlisiso le nts'etsopele ea RDP e baballang tikoloho le eona e tla ba tataiso ea bohlokoa ho fihlela litlhoko tsa meaho e tala.
Redispersible latex powder (RDP) e phetha karolo ea bohlokoa ho matlafatsa matla a tlamahano ea li-adhesive tsa lithaele. RDP e ka ntlafatsa haholo ts'ebetso ea likhomaretsi tsa lithaele ka mekhoa e fapaneng e kang ho feto-fetoha ha maemo, ho ntlafala ha metsi le nako e bulehileng, le ho eketsa matla a kopaneng. Khetho e utloahalang le ho eketsoa ha RDP ho tla thusa ho finyella phello e ntle ka ho fetisisa ea ho kopanya le ho netefatsa botsitso ba nako e telele le ho tšoarella ha lithaele.
