Redispersible polymer powder (RDP) ke motsoako oa bohlokoa oa polymer o sebelisetsoang ho ntlafatsa ts'ebetso ea lisebelisoa tse entsoeng ka samente, tsa gypsum, tse entsoeng ka lime le tse entsoeng ka lime. RDP e ntlafatsa ts'ebetso e felletseng ea lisebelisoa tsena ka ts'ebetso ea eona ea tlamahano, ho matlafatsa, ho hanyetsa mapheo, ho hanyetsa metsi, joalo-joalo, 'me e sebelisoa haholo ho thepa ea mohaho.
Mefuta e meholo ea RDP
Mefuta ea RDP e arotsoe haholo ho latela mofuta oa substrate eo e entsoeng ka eona, sebaka sa ts'ebeliso le litšobotsi tsa ts'ebetso. Li-RDP tse tloaelehileng li kenyelletsa tse latelang:
Mofuta oa ethylene-vinyl acetate copolymer (EVA):
Likarolo: Ethylene-vinyl acetate copolymer ke e 'ngoe ea mefuta e tloaelehileng ea RDP. E na le phetoho e babatsehang le ho khomarela, 'me e fana ka khanyetso e ntle ea metsi le ho hanyetsa boemo ba leholimo.
Kopo: Haholo-holo e sebelisoa ka likhomaretsi tsa lithaele, lisebelisoa tsa fatše tse ikemetseng, lisebelisoa tsa ka ntle tsa marako le masimo a mang.
Melemo: E fana ka boima bo botle le ho tenyetseha, e loketseng liketsahalo tse hlokang ho tenyetseha le ho khomarela ho itseng.
Mefokolo: Ka lebaka la ethylene e phahameng, tshebetso ea eona e ka 'na ea se ke ea lekana hanyenyane lits'ebetsong tse ling tse nang le litlhoko tse phahameng tsa matla.
Mofuta oa Ethylene-vinyl acetate-vinyl acetate terpolymer (VeoVa/EVA):
Likarolo: Mofuta ona oa RDP o kenyelletsa VeoVa (vinyl ester) motheong oa ethylene le vinyl acetate copolymerization, e ntlafatsang ho hanyetsa metsi le botsitso ba lik'hemik'hale tsa thepa.
Kopo: E sebelisoa hangata ka har'a masela a kantle a lebota le lihlahisoa tsa gypsum, jj.
Melemo: E na le khanyetso e ntle ea metsi le khanyetso ea lik'hemik'hale, e loketseng lits'ebetso tsa kantle le tse thata tsa lik'hemik'hale.
Mathata: Ha ho bapisoa le mofuta oa EVA oa setso, litšenyehelo li ka ba holimo hanyane.
Mofuta oa styrene-butadiene copolymer (SB):
Likarolo: Haholo-holo e entsoe ka styrene le butadiene monomers, 'me e na le thepa e ntle ea tlamahano, ho feto-fetoha ha maemo le ho hanyetsa metsi.
Kopo: Hangata e sebelisoa ho li-adhesive tsa lithaele le li-putty tse feto-fetohang.
Melemo: Tlamahano e ntle le ho feto-fetoha ha maemo, hape le ts'ebetso e babatsehang ea ho thibela metsi.
Mefokolo: E ka tsofala tlas'a khanya ea ultraviolet.
Mofuta oa vinyl acetate-ethylene copolymer (VAE):
Likarolo: Ke copolymer ea vinyl acetate le ethylene, e nang le maemo a holimo haholo le ho hanyetsa metsi.
Kopo: E loketse li-adhesives tsa lithaele, lisebelisoa tsa ka ntle tsa marako a ka ntle, li-self-leveling tsa gypsum, joalo-joalo.
Melemo: E fana ka ho khomarela hantle le ho thibela metsi, 'me e na le lik'hemik'hale tse itseng tse hanyetsang.
Mathata: Theko e batla e phahame.
Mofuta oa Acrylic copolymer (Acrylic):
Likarolo: Karolo e ka sehloohong ke acrylic ester, e nang le ho khomarela hantle le ho feto-fetoha ha maemo.
Kopo: E sebelisoa haholo ka seretse se khabisitsoeng, sekhomaretsi sa lithaele, gypsum le lisebelisoa tse ling.
Melemo: Ho khomarela hantle le ho feto-fetoha ha maemo, le khanyetso e ntle ea UV.
Mefokolo: Ka lebaka la theko e phahameng ea thepa ea acrylic, theko ea mofuta ona oa RDP e boetse e phahame.
Mesebetsi le ts'ebeliso ea RDP
Ts'ebetso e ntlafalitsoeng ea bonding:
RDP e bapala karolo ea borokho ho thepa, e matlafatsa sekhomaretsi, 'me e ntlafatsa maqhama lipakeng tsa thepa ea moaho le substrate.
Libaka tsa kopo li kenyelletsa li-adhesives tsa lithaele, li-bonding mortars, joalo-joalo.
Ho ntlafatsa ho feto-fetoha ha maemo le ho hanyetsa ho phatloha: Ka ho eketsa RDP, ho feto-fetoha ha thepa ho ntlafatsoa haholo, e leng ho thusang ho thibela ho hlaha ha mapheo.
E sebelisoa hangata lits'ebetsong tsa insulation, putty e feto-fetohang, lisebelisoa tsa ho lokisa, jj.
Ho ntlafala ha metsi le ho hanyetsa metsi:
RDP e ntlafatsa ho hanyetsa metsi ha thepa, ho e lumella ho boloka ts'ebetso e tsitsitseng sebakeng se mongobo.
E sebelisoa ka lirapeng tse sa keneleng metsi, lirapeng tse ka ntle tsa lebota, joalo-joalo.
Mosebetsi o ntlafetseng oa kaho:
RDP e ka ntlafatsa ts'ebetso ea kaho ea thepa ea phofo e omeletseng, ea etsa hore kaho e be bonolo le ho sebetsa hantle.
E sebelisoa haholo ka thepa ea fatše ea ho ikemela, liaparo, joalo-joalo.
Ho ntlafala ho tšoarella le ho hanyetsa boemo ba leholimo: Ka lebaka la ho eketsoa ha RDP, ho tšoarella le ho hanyetsa boemo ba leholimo ba thepa ho ntlafatsoa haholo, 'me e khona ho mamella teko ea maemo a thata.
E sebelisoa ho litsamaiso tsa ka ntle tsa marako, marulelo a marulelo, joalo-joalo.
Lintlha tsa ho khetha RDP e loketseng
Maemo a ts'ebeliso:
Khetha mofuta o nepahetseng oa RDP ho latela maemo a ts'ebeliso e khethehileng, mohlala, lits'ebetso tsa kantle li hloka RDP e nang le khanyetso e ntle ea boemo ba leholimo.
Taolo ea litšenyehelo:
Motheong oa ho netefatsa ts'ebetso, hoa hlokahala ho nahana ka litšenyehelo tsa thepa le ho khetha RDP ea moruo.
Tšebelisano:
RDP e hloka ho lumellana hantle le lisebelisoa tse ling ho netefatsa botsitso le ts'ebetso e tsitsitseng ea motsoako.
Litlhoko tsa ts'ebetso:
Khetha mofuta o nepahetseng oa RDP ho ea ka thepa e hlokahalang (e kang ho tenyetseha, ho khomarela, ho hanyetsa metsi, joalo-joalo).
Redispersible latex powder e phetha karolo ea bohlokoa thepa ea sejoale-joale ea moaho, 'me mefuta ea eona e fapaneng e fana ka tharollo e bonolo bakeng sa litlhoko tse fapaneng tsa kaho. Ho khetha mofuta o nepahetseng oa RDP ho ka ntlafatsa haholo ts'ebetso ea thepa ea kaho, ka hona ho ntlafatsa boleng le ho tšoarella ha merero ea kaho.
