Li-polymer powders tse ka sebelisoang hape ke eng?

Redispersible polymer powders (RPP) ke phofo e sa lefelloeng, e tšoeu e hlahisoang ke li-dispersions tsa polymer tse omisang kapa li-emulsion.Li na le likaroloana tsa polymer tse koahetsoeng ka lisebelisoa tse sireletsang le li-additives.Ha li kopane le metsi, li-powders tsena li hasana habonolo ho etsa li-emulsion tsa polymer tse tsitsitseng, tse nolofalletsang tšebeliso ea tsona mefuteng e mengata ea lisebelisoa tsa kaho, lipente le liphahlo, likhomaretsi le liindasteri tse ling.

Moetso:

Sebopeho sa li-polymer powders tse ka sebelisoang hape hangata se kenyelletsa likarolo tse latelang:

1. Polymer Particles: Karolo e ka sehloohong ea RPP ke likaroloana tsa polymer, tse nkiloeng ho li-polymer tse fapaneng tsa maiketsetso tse kang vinyl acetate-ethylene (VAE), ethylene-vinyl acetate (EVA), acrylics, styrene-butadiene (SB), kapa polyvinyl acetate ( PVA).Li-polymer tsena li kenya letsoho ho thepa e lakatsehang le litšobotsi tsa ts'ebetso ea sehlahisoa sa ho qetela.
2. Lisebelisoa tsa Tšireletso: Ho thibela likaroloana tsa polymer hore li se ke tsa kopana nakong ea polokelo le lipalangoang, lisebelisoa tse sireletsang tse kang polyvinyl alcohol (PVA) kapa cellulose ethers hangata li sebelisoa.Mahlahana ana a tsitsisa likaroloana tsa polymer le ho etsa bonnete ba hore li ka boela tsa fetoha ka metsing.
3. Li-Plasticizers: Li-plasticizers li ka eketsoa ho ntlafatsa ho feto-fetoha ha maemo, ho sebetsa le ho khomarela li-RPP.Li-additives tsena li thusa ho ntlafatsa ts'ebetso ea likaroloana tsa polymer lits'ebetsong tse fapaneng, haholo lirapeng tse tenyetsehang, likhomaretsi le li-sealant.
4. Li-Fillers le Li-Additives: Ho ipapisitsoe le litlhoko tse ikhethileng tsa kopo, li-filler, li-pigment, li-crosslinking agents, li-thickeners, le li-additives tse ling li ka kenyelletsoa libopeho tsa RPP ho ntlafatsa thepa ea bona kapa ho fana ka ts'ebetso e itseng.

Thepa le Litšobotsi:

Li-polymer powders tse ka sebelisoang hape li bonts'a thepa le litšoaneleho tse 'maloa tse li etsang hore li feto-fetohe le ho sebelisoa haholo liindastering tse fapaneng:

1. Redispersibility: RPP e qhalakana habonolo ka metsing ho etsa li-emulsion tse tsitsitseng tsa polymer kapa li-dispersions, e leng ho lumellang ho kenngoa habonolo ho lihlahisoa le ts'ebeliso e latelang.
2. Bokhoni ba ho Etsa Lifilimi: Ha e hasane ka metsing 'me e sebelisoa holim'a metsi, RPP e ka etsa lifilimi tse tšesaane, tse tsoelang pele ha li omisoa.Lifilimi tsena li ntlafatsa ho khomarela, ho tšoarella, le ho hanyetsa boemo ba leholimo ka lirafshoa, likhomaretsi le li-sealants.
3. Ntlafatso ea Khomarelo: RPP e ntlafatsa ho khomarela pakeng tsa li-substrates le li-coat, lirekere, kapa li-adhesives, e leng se hlahisang litlamo tse matla le ts'ebetso e ntlafetseng ea thepa ea kaho le ea mohaho.
4. Ho Boloka Metsi: Sebopeho sa hydrophilic sa RPP se ba nolofalletsa ho monya le ho boloka metsi ka har'a lihlahisoa, ho lelefatsa hydration le ho ntlafatsa ts'ebetso, nako e bulehileng, le ho khomarela lits'ebetsong tsa seretse le sekhomaretsi sa lithaele.
5. Ho feto-fetoha ha maemo le ho tiea: Thepa e fetotsoeng ea RPP e bonts'a ho fetoha ha maemo, elasticity, le ho tiea, ho etsa hore li se ke tsa hlola li senya, ho senyeha le ho senya.
6. Khanyetso ea Boemo ba Leholimo: Li-RPP li ntlafatsa ho hanyetsa boemo ba leholimo le ho tšoarella ha lirafshoa, li-sealant le li-membrane tse thibelang metsi, li fana ka tšireletso ea nako e telele khahlano le mahlaseli a kotsi a UV, mongobo le maemo a tikoloho.

Lisebelisoa:

Li-polymer powders tse ka sebelisoang hape li fumana lits'ebetso indastering le lihlahisoa tse fapaneng, ho kenyelletsa:

• Kaho: Likhomaretsi tsa lithaele, seretse, li-grouts, li-membrane tse thibelang metsi, metsoako ea ho ikemela, le lisebelisoa tsa ka ntle tsa ho pata le ho qeta (EIFS).
• Lipente le Mekhabiso: Lipente tsa ka ntle, lirafshoa tse entsoeng ka masela, lipolasetere tse khabisitsoeng le liphahlo tsa meralo.
• Likhomaretsi le Li-Sealants: Likhomaretsi tsa lithaele, li-crack fillers, li-caulks, li-sealant tse feto-fetohang, le likhomaretsi tse mamellang khatello.
• Textile: Liaparo tsa masela, li-finishing agents, le metsoako ea boholo.

Redispersible polymer powders ke lisebelisoa tse fapaneng le tse sebetsang ka bongata tse sebelisetsoang ho ntlafatsa ts'ebetso, ho tšoarella, le ho feto-fetoha ha lihlahisoa tse fapaneng le libopeho tsa kaho, lipente le likoahelo, likhomaretsi, masela le liindasteri tse ling.
