Redispersible Polymer: Ho ntlafatsa Ts'ebetso ea Sehlahisoa

Redispersible polymer powders (RDP) e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea lihlahisoa tse fapaneng, haholo lisebelisoa tsa kaho. Mona ke kamoo li-RDP li kenyang letsoho ho ntlafatseng tšebetso ea sehlahisoa:

1. Khomarelo e Ntlafetseng: Li-RDP li ntlafatsa ho khomarela lisebelisoa tsa kaho tse kang likhomaretsi tsa lithaele, lirekere le li-substrate. Ba theha maqhama a matla pakeng tsa thepa le substrate, ho netefatsa ho khomarela nako e telele le ho thibela delamination kapa detachment.
2. Ntlafatso e Felletseng le Khanyetso ea Crack: Li-RDP li ntlafatsa ho feto-fetoha ha maemo le ho hanyetsa ho phatloha ha thepa ea samente e kang liretse le metsoako ea ho ikemela. Li thusa ho fokotsa ho fokotseha le ho phunyeha ka ho ntlafatsa momahano le elasticity ea thepa, e leng se etsang hore ho be le mehaho e tšoarellang le e tsitsitseng.
3. Ho hanyetsa Metsi le ho Tšoara Nako e Tšoarellang: Li-RDP li matlafatsa ho thibela metsi le ho tšoarella ha thepa ea kaho, li etsa hore li tšoanelehe bakeng sa lisebelisoa tsa ka hare le tsa ka ntle. Li ntlafatsa ho hanyetsa ha thepa ho kenella ha metsi, potoloho ea ho qhibiliha ha metsi, le boemo ba leholimo, ho lelefatsa bophelo ba ts'ebeletso le ho boloka botsitso ba sebopeho.
4. Likarolo tse Ntlafetseng tsa ho sebetsa le ho sebelisa thepa: Li-RDP li ntlafatsa ho sebetsa le ho sebelisoa ha thepa ea kaho, e leng ho etsang hore ho be bonolo ho kopanya, ho jala le ho qeta. Li ntlafatsa ho phalla le ho tsitsisa ha thepa, e leng se etsang hore ho be le libaka tse boreleli le liphetho tse tšoanang.
5. Tlhophiso e Laolang le Linako tsa Phekolo: Li-RDP li thusa ho laola maemo le ho phekola linako tsa thepa ea samente, e lumellang hore ho sebetse hantle le linako tse atolositsoeng tsa ho bula. Li laola tšebetso ea hydration, ho netefatsa pheko e nepahetseng le ho fokotsa kotsi ea ho beha kapa ho omisa pele ho nako.
6. Momahano e Matlafalitsoeng le Matla: Li-RDP li ntlafatsa momahano le matla a thepa ea kaho, e leng se hlahisang matla a holimo a tlamo le botsitso ba sebopeho. Ba matlafatsa matrix a thepa, ba eketsa matla a eona a ho jara le ho hanyetsa khatello ea mochine.
7. Ho Ntlafala ha Leqhoa-Thaha: Li-RDP li matlafatsa botsitso ba ho qhibiliha ha thepa ea samente, ho fokotsa kotsi ea ho senyeha kapa ho senyeha ha maemo a leholimo a batang. Ba fokotsa ho kenella ha metsi mme ba thibela ho thehoa ha likristale tsa leqhoa, ho boloka botšepehi le ts'ebetso ea thepa.
8. Ho lumellana le Li-additives: Li-RDP li lumellana le mefuta e mengata ea li-additives tse atisang ho sebelisoa thepa ea kaho, tse kang li-accelerator, li-retarders le li-air-entraining agents. Sena se lumella ho fetoha ha maemo ha ho etsoa le ho nolofalletsa ho iketsetsa lihlahisoa ho finyella litlhoko tse khethehileng tsa tshebetso.

Ka kakaretso, li-polymer powders tse ka sebelisoang hape li bapala karolo ea bohlokoa ho ntlafatsa ts'ebetso ea thepa ea kaho ka ho ntlafatsa ho khomarela, ho tenyetseha, ho hanyetsa metsi, ho tšoarella, ho sebetsa, ho beha le ho phekola linako, momahano, matla, botsitso ba leqhoa le ho lumellana le lisebelisoa. Tšebeliso ea bona e kenya letsoho ho hlahiseng lihlahisoa tsa boleng bo phahameng le tse ka tšeptjoang tsa kaho tse loketseng likopo tse sa tšoaneng le maemo a tikoloho.
