Powder ea Re-Dispersible Polymer e sebelisetsoa eng?

Redispersible polymer powder (RDP) ke tlatsetso e feto-fetohang le e sebelisoang haholo liindastering tse fapaneng, haholo mesebetsing ea kaho, lipente le likoahelo, likhomaretsi le litlhare. Mofuta ona oa phofshoana oa polima o entsoe ka mokhoa o bitsoang spray drying, moo emulsion ea polymer e fetoloang phofo e sa lefelloeng. RDP e entsoe ka setsi sa polymer, joalo ka vinyl acetate ethylene (VAE), vinyl acetate versatate (VAC / VeoVa), kapa li-acrylics, hammoho le li-additives tse kang li-dispersants, plasticizers le colloids tse sireletsang. Lintho tsa eona tse ikhethang li etsa hore e be ea bohlokoa bakeng sa mefuta e mengata ea likopo. Mona ke tlhahlobo e felletseng ea ts'ebeliso ea phofo ea polymer e ka qhalehang liindastering tse fapaneng:

Indasteri ea Kaho:

1. Li-Adhesives tsa Lithaele: RDP ke karolo ea bohlokoa ho li-adhesives, moo e ntlafatsang ho khomarela li-substrates, ho feto-fetoha ha maemo, le ho hanyetsa metsi. E etsa bonnete ba ho tšoarella ha bokaholimo ba lithaele lits'ebetsong tsa kahare le kantle.

Li-Grouts le Joint Fillers: RDP e ntlafatsa ho khomarela, ho tenyetseha, le ho hanyetsa metsi ha li-grouts le li-filler tse kopanetsoeng tse sebelisoang ho kenya lithaelese le lits'ebetso tsa masonry. E thibela ho kenella ha mongobo 'me e sireletsa khahlanong le litšila le kholo ea likokoana-hloko.

Indasteri ea Lipente le Mekhabiso:

1. Emulsion Paints: RDP e sebetsa e le setlamo sa lipente tsa emulsion, ho fana ka sebopeho sa filimi, ho khomarela li-substrates, le botsitso ba mechine. E matlafatsa ho hanyetsa ho hohla, ho hlatsuoa, le ho boloka mebala ka lipente tse kahare le kantle.
2. Liaparo tsa Textured: Lirapeng tse entsoeng ka masela le likhabiso tse khabisitsoeng, RDP e ntlafatsa ho khomarela li-substrates, ho boloka sebopeho le ho hanyetsa boemo ba leholimo. E thusa ho theha libaka tse khahlehang le tse tšoarellang.
3. Liaparo tsa Cementitious: RDP e sebelisoa ka liphahlo tsa samente bakeng sa tšireletso ea kantle ea konkreite le bokaholimo ba masonry. E ntlafatsa ho khomarela, ho tenyetseha, le ho hanyetsa carbonation, chloride ingress, le ho kenella ha metsi.
4. Elastomeric Coatings: RDP e kenyellelitsoe ka har'a liphahlo tsa elastomeric ho ntlafatsa ho tenyetseha, bokhoni ba ho koala le ho hanyetsa boemo ba leholimo. E netefatsa tšireletso ea nako e telele ea marako a ka ntle le li-facade khahlanong le mongobo le khatello ea tikoloho.

Indasteri ea Likhomaretsi:

1. Li-Adhesives tsa Dry-Mix Mortar: RDP ke tlatsetso ea bohlokoa ho likhomaretsi tsa seretse sa motsoako o omileng bakeng sa ho kopanya lithaele, litene le majoe ho li-substrates tse fapaneng. E fana ka ho khomarela ka matla, ho feto-fetoha ha maemo, le ho hanyetsa metsi, ho netefatsa litlamo tse tšoarellang le tse tšoarellang nako e telele.
2. Likhomaretsi tsa Wallpaper: Ka har'a likhomaretsi tsa pampiri, RDP e ntlafatsa masela, ho khomarela li-substrates, le ho behoa hape. E etsa bonnete ba hore li-wallpaper li khomarela ka mokhoa o boreleli le ka mokhoa o ts'oanang ho marako, li thusa ho kenya le ho tlosoa habonolo.
3. Likhomaretsi tsa Kaho: RDP e matlafatsa matla a tlamo, ho tenyetseha, le ho tšoarella ha likhomaretsi tsa kaho tse sebelisoang ho kopanya thepa ea moaho joalo ka lehong, tšepe le polasetiki. E tiisa maqhama a ka tšeptjoang le a nako e telele lits'ebetsong tsa meralo le tse seng tsa sebopeho.

Indasteri ea Litlhare:

1. Liaparo tsa Letlapa: RDP e sebelisoa mefuteng ea meriana e le ntho ea ho etsa filimi bakeng sa ho roala letlapa. E fana ka tšireletso ea mongobo, masking a tatso, le ho lokolloa ho laoloang ha metsoako e sebetsang, ho matlafatsa ts'ebetso le botsitso ba mefuta ea litekanyetso tsa molomo.
2. Meetso ea lihlooho: Metsoakong ea lihlooho tse kang litlolo, litlolo, le li-gel, RDP e sebetsa e le ntho e matlafatsang le ho tsitsisa. E ntlafatsa thepa ea rheological, ho ata, le sebopeho sa libopeho, ho netefatsa ts'ebetso e ts'oanang le letlalo la letlalo.
3. Oral Dispersible Powders: RDP e sebelisoa ka liphofshoana tse qhalakahang ka molomo bakeng sa lisebelisoa tsa meriana le tsa phepo. E ntlafatsa phallo, dispersibility, le botsitso ba phofo, ho nolofatsa dosing e nepahetseng le ho qhibiliha ka potlako molomong.

Liindasteri tse ling:

1. Pampiri le Masela: RDP e sebelisoa ho koahela lipampiri le li-binders tsa masela ho ntlafatsa matla, boreleli ba bokaholimo le ho hatisoa. E ntlafatsa ts'ebetso ea lihlahisoa tsa pampiri le lisebelisoa tsa masela lits'ebetsong tse fapaneng.
2. Lihlahisoa tsa Tlhokomelo ea Motho: Lihlahisoang tsa tlhokomelo ea motho joalo ka li-gels tsa setaele sa moriri le litlolo, RDP e sebetsa joalo ka motenya le ho tsitsisa. E fana ka viscosity, sebopeho, le ho tšoarella ha nako e telele ho litlhophiso, ho ntlafatsa ts'ebetso ea bona le boiphihlelo ba basebelisi.
3. Mekhoa ea ho Thibela Mollo: RDP e kenyelelitsoe mefuteng e thibelang mollo ho ntlafatsa phallo ea lisebelisoa tse thibelang mollo le ho ntlafatsa ts'ebetso ea tsona. E kenya letsoho ho hanyetsa mollo oa lisebelisoa ka mekhoa e sa tšoaneng, ho akarelletsa le kaho le masela.

Qetellong, redispersible polymer powder (RDP) e fumana tšebeliso e pharaletseng ho pholletsa le liindasteri tse fapaneng, ka lebaka la thepa ea eona e fapaneng le mesebetsi. Ebang ke ho ntlafatsa ho tšoarella ha lisebelisuoa tsa kaho, ho ntlafatsa tšebetso ea lipente le lirafshoa, ho thusa ho tiisa likhomaretsi, kapa ho ntlafatsa metsoako ea metsoako ea meriana le makaleng a mang, RDP e bapala karolo ea bohlokoa ho ntlafatseng boleng ba sehlahisoa, ts'ebetso le botsitso. Ha mahlale a ntse a fetoha le liindasteri li ntse li nchafala, tlhoko ea RDP e lebelletsoe ho tsoela pele ho hola, e tsamaisang tsoelopele le lits'ebetso tse ling ho potoloha mmaraka oa lefatše.
