Lintlha tsa phofo ea emulsion e ka sebelisoang hape

Redispersible Emulsion Powder (RDP), eo hape e tsejoang e le redispersible polymer powder, ke phofo e sa lefelloeng, e tšoeu e fumanoang ka ho omisa emulsion ea vinyl acetate-ethylene copolymer kapa li-polymer tse ling. Ke tlatsetso e feto-fetohang e sebelisoang linthong tsa kaho ho ntlafatsa thepa e kang ho khomarela, ho tenyetseha, ho sebetsa le ho hanyetsa metsi. Mona ke lintlha tse mabapi le phofo ea emulsion e ka sebelisoang hape:

Moetso:

• Polymer Base: Karolo ea mantlha ea RDP ke polymer ea maiketsetso, eo hangata e leng vinyl acetate-ethylene (VAE) copolymer. Li-polymer tse ling tse kang vinyl acetate-vinyl versatate (VA/VeoVa) copolymers, ethylene-vinyl chloride (EVC) copolymers, le acrylic polymers le tsona li ka sebelisoa ho itšetlehile ka thepa e lakatsehang.
• Protective Colloids: RDP e ka 'na ea e-na le li-colloid tse sireletsang tse kang cellulose ethers (mohlala, hydroxypropyl methylcellulose), polyvinyl alcohol (PVA), kapa starch ho ntlafatsa botsitso le ho senyeha hape.

Mokhoa oa Tlhahiso:

1. Emulsion Formation: Polymer e hasane ka metsing hammoho le lisebelisoa tse ling tse kang li-colloids tse sireletsang, li-plasticizers le li-dispersing agents ho etsa emulsion e tsitsitseng.
2. Spray Drying: Emulsion e entsoe ka athomo ebe e fafatsoa ka phaposing ea ho omisa moo moea o chesang o etsang mouoane oa metsi, o siea ka morao likaroloana tse tiileng tsa polymer. Likaroloana tse omisitsoeng li bokelloa 'me li arotsoe ho fumana kabo ea boholo bo lakatsehang.
3. Ka mor'a Kalafo: Likaroloana tse omisitsoeng li ka 'na tsa e-ba le mekhoa ea ka mor'a phekolo e kang ho fetola bokaholimo, granulation, kapa ho kopanya le li-additives tse ling ho ntlafatsa thepa e kang redispersibility, flowability, le ho lumellana le likarolo tse ling ha li etsoa.

Thepa:

• Redispersibility: RDP e bonts'a phepelo e ntle ka ho fetesisa metsing, e etsa li-dispersions tse tsitsitseng tse ts'oanang le emulsion ea mantlha ha e khutlisetsoa metsi. Thepa ena e netefatsa kabo e ts'oanang le ts'ebetso e ts'oanang lits'ebetsong tsa kaho.
• Tlhahiso ea Lifilimi: Likaroloana tsa RDP li ka kopana 'me tsa etsa lifilimi tse tsoelang pele tsa polymer ha li omisoa, li fana ka ho khomarela, ho tenyetseha, le ho tšoarella ho thepa ea kaho e kang lirekere, likhomaretsi le li-grouts.
• Poloko ea Metsi: RDP e ntlafatsa ho bolokoa ha metsi lits'ebetsong tsa samente, ho fokotsa tahlehelo ea metsi nakong ea ho beha le ho phekola le ho ntlafatsa ts'ebetso, ho khomarela le matla a ho qetela.
• Flexibility le Crack Resistance: Filimi ea polymer e entsoeng ke RDP e fana ka ho feto-fetoha ha maemo le ho hanyetsa mapheo ho thepa ea kaho, ho fokotsa kotsi ea ho phunyeha le ho senya.
• Tšebelisano: RDP e lumellana le mefuta e mengata e fapaneng ea li-binders tsa cementitious, li-filler, li-aggregate, le li-additives tse sebelisoang mefuteng ea kaho, e lumellang hore ho sebelisoe mefuta e mengata le mekhoa e mengata.

Lisebelisoa:

• Likhomaretsi tsa Lithaele le Li-Grouts: RDP e ntlafatsa ho khomarela, ho feto-fetoha ha maemo, le ho hanyetsa metsi ka har'a li-adhesives le li-grouts, ho netefatsa hore ho kenngoa ha nako e telele le ho tšoarella nako e telele.
• Exterior Insulation and Finish Systems (EIFS): RDP e ntlafatsa ho feto-fetoha ha maemo, ho hanyetsa boemo ba leholimo, le ho hanyetsa ho phatloha ha liphahlo tsa EIFS, ho fana ka tšireletso le boipiletso bo botle ho marako a ka ntle.
• Metsoako ea ho Ikemela: RDP e ntlafatsa phallo, boemo, le pheletso ea bokaholimo ka metsoako ea ho ikemela, e bakang mekato e boreleli.
• Lokisa Li-Mortars le Renders: RDP e ntlafatsa ho khomarela, ho tšoarella, le ho hanyetsa mapheo ho lirekere tsa ho lokisa le ho fana, ho tsosolosa le ho matlafatsa mehaho ea konkreite e senyehileng.

Redispersible Emulsion Powder (RDP) e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso le ho tšoarella ha thepa ea kaho, ho kenya letsoho boleng le bophelo bo bolelele ba merero ea kaho. Ho feto-fetoha ha eona, ho tsamaellana le katleho ho etsa hore e be tlatsetso ea bohlokoa lits'ebetsong tse fapaneng tsa kaho.
