Li-polymer powders tse ka sebelisoang hape ke eng?

Redispersible polymer powders (RPP) ke phofshoana 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 fumaneha liindastering 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.
