Redispersible polymer powders (RDP) ke lisebelisoa tsa bohlokoa tse sebelisoang liindastering tse fapaneng, haholo-holo kahong, bakeng sa ho ntlafatsa thepa ea thepa e thehiloeng ho samente le lits'ebetso tse ling. Mona ke kakaretso ea li-polymer powders tse ka sebelisoang hape:

1. Sebopeho:

• Li-polymer powders tse ka sebelisoang hape hangata li entsoe ka li-resin tsa polymer, li-plasticizers, lisebelisoa tse hasaneng, le li-additives tse ling.
• Polima e ka sehloohong e sebelisoang ho RDPs hangata ke copolymer ea vinyl acetate le ethylene (VAE), le hoja li-polymer tse ling tse kang acrylics le tsona li ka sebelisoa.

2. Mokhoa oa Tlhahiso:

• Ho hlahisa li-polymer powders tse ka sebelisoang hape ho kenyelletsa emulsion polymerization ea li-monomers ho etsa li-dispersions tsa polymer.
• Kamora 'polymerization, metsi a ntšoa ho tsoa ho qhalaneng ho hlahisa polima e tiileng ka mokhoa oa phofo.
• Phofo e hlahisoang e ntse e sebetsoa ka ho eketsehileng ho ntlafatsa thepa ea eona ea ho tsosolosa le ho phalla.

3. Thepa:

• Li-polymer powders tse qhalakahang li phalla ka bolokolohi, li phofshoana tse qhalakahang habonolo tse ka kopanngoang habonolo le metsi ho etsa phallo e tsitsitseng.
• Li na le thepa e ntle ea ho etsa lifilimi le ho khomarela li-substrates tse fapa-fapaneng, tse etsang hore li tšoanelehe ho sebelisoa mefuteng e mengata ea likopo.
• Li-RDP li ntlafatsa ho feto-fetoha ha maemo, ho hanyetsa metsi, ho tšoarella, le ho sebetsa ha thepa e entsoeng ka samente e kang seretse, likhomaretsi tsa lithaele le metsoako ea ho ikemela.

4. Likopo:

• Indasteri ea Kaho: Li-RDP li sebelisoa haholo lihlahisoa tsa samente tse kang likhomaretsi tsa lithaele, li-grouts, metsoako e itšebetsang, li-insulation tsa ka ntle le litsamaiso tsa ho qetela (EIFS), le li-membrane tse thibelang metsi ho ntlafatsa thepa le ts'ebetso ea tsona.
• Lipente le Liaparo: Li-RDP li sebelisoa e le li-binders, thickeners, le li-agents tsa ho etsa lifilimi lipenteng tsa metsi, li-coatings le li-sealants ho ntlafatsa ho khomarela, ho tenyetseha le ho tšoarella.
• Masela: Li-RDP li sebelisoa ka masela a masela 'me li qeta ho ntlafatsa thepa ea masela joalo ka ho leleka metsi, ho hanyetsa matheba le ho hanyetsa mats'oenyeho.
• Lipampiri le Liphutheloana: Li-RDP li sebelisoa ho koahela pampiri le likhomaretsi ho ntlafatsa matla, ho hatisoa le thepa ea thibelo.

5. Melemo:

• Ntlafatso ea Khomarelo: Li-RDP li ntlafatsa ho khomarela lisebelisoa tsa samente ho li-substrates tse fapaneng, ho kenyeletsoa konkreite, patsi, tšepe le polasetiki.
• E Eketsehile ho Fetoha: Li-RDP li ntlafatsa ho feto-fetoha ha maemo le ho hanyetsa ho phunyeha ha thepa e entsoeng ka samente, ho etsa hore e tšoarelle nako e telele le ho hanyetsa ho senyeha.
• Mathata a Metsi: Li-RDP li fana ka thepa e thibelang metsi le e thibelang metsi lihlahisoa tsa samente, li fokotsa ho monyela ha metsi le ho matlafatsa nako e telele.
• Mosebetsi: Li-RDP li ntlafatsa ho sebetsa le ho ata ha thepa e thehiloeng ho samente, e leng ho nolofalletsang ts'ebeliso e bonolo le ho qeta hamolemo.

6. Maikutlo a Tikoloho:

• Meetso e mengata ea RDP e theiloe holim'a metsi, 'me ha e na tikoloho, e kenya letsoho lits'ebetsong tse tsitsitseng tsa kaho.
• Li-RDP li ka thusa ho fokotsa tšusumetso ea tikoloho ea mesebetsi ea kaho ka ho ntlafatsa ho tšoarella le ho phela nako e telele ha thepa ea moaho.

Qetello:

Li-polymer powders tse ka sebelisoang hape li bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso le thepa ea thepa e thehiloeng ho samente liindastering tse fapaneng. Ho feto-fetoha ha tsona, ho tšoarella ha tsona, le melemo ea tikoloho li li etsa litlatsetso tsa bohlokoa bakeng sa ho ntlafatsa boleng le ho tšoarella ha merero ea kaho le lits'ebetso tse ling. Ha tlhoko ea ts'ebetso e phahameng ea ts'ebetso, lisebelisoa tsa moaho tse bolokang tikoloho e ntse e hola, ts'ebeliso ea phofo ea polymer e ka sebelisoang hape e lebelletsoe ho eketseha, e leng ho tsamaisang boqapi bo eketsehileng le nts'etsopele tšimong ena.
