Redispersible latex powder, eo hape e tsejoang e le redispersible polymer powder kapa RDP, ke motsoako oa bohlokoa oa thepa ea morao-rao ea kaho, haholo-holo tšimong ea seretse se omileng.Liphofshoana tsena li sebelisoa haholo liindastering tse fapaneng tse kenyelletsang kaho, lipente le lirafshoa, likhomaretsi, masela le litlhare, har'a tse ling.
1. Kenyelletso ea phofo ea latex e ka sebelisoang hape:
Redispersible latex powder ke phofo ea polymer e phallang e sa lefelloeng e fumanoang ka ho omisa ka metsi a pharalletseng a polymer.E na le motsoako oa li-polymers tsa maiketsetso, hangata vinyl acetate-ethylene (VAE) copolymer, le li-additives tse fapaneng tse kang li-colloids tse sireletsang, li-plasticizers le li-dispersants.Morero o ka sehloohong oa phofo ea latex e ka sebelisoang hape ke ho ntlafatsa ts'ebetso ea lisebelisoa tsa mohaho, ho fana ka thepa ea bohlokoa e kang ho khomarela, ho feto-fetoha ha maemo, ho hanyetsa metsi le ho sebetsa.
2. Mokhoa oa tlhahiso:
Ho hlahisa phofo ea latex e ka sebelisoang hape ho kenyelletsa mehato e mengata ea bohlokoa:
A. polymerization:
Ts'ebetso e qala ka emulsion polymerization ea li-monomers tse kang vinyl acetate le ethylene ka pel'a li-initiators le li-surfactants.Mohato ona o hlahisa ho hasana ka metsi ha likaroloana tsa polymer.
b.Ho omisa:
Aqueous dispersion e ntan'o omisoa ka ho fafatsa, e kenngoa ka athomo hore e be marotholi 'me e omisoe kapele ka moea o chesang.Phofo e hlahisoang e na le likaroloana tse nyane tsa polymer tse kentsoeng ka colloid e sireletsang.
C. Ka mor'a ts'ebetso:
Ka mor'a ts'ebetso ea ts'ebetso e ka etsoa ho ntlafatsa thepa ea phofo.Tsena li ka kenyelletsa ho omisa ho eketsehileng, ho fetola bokaholimo kapa ho eketsa li-additives.
3. Sebopeho:
Redispersible latex powder hangata e na le metsoako e latelang:
Sekhomaretsi sa polymer: Hangata motsoako o ka sehloohong ke copolymer ea vinyl acetate le ethylene, e fanang ka thepa ea ho etsa filimi le ho khomarela.
Li-colloids tse sireletsang: Lintho tsena li thibela ho kopana ha likaroloana tsa polymer nakong ea polokelo le ho netefatsa hore li-dispersibility li ntle.
Plasticizers: Ntlafatsa ho fetoha le maemo le ts'ebetso ea sehlahisoa sa ho qetela.
Li-dispersants: Li-powders li thusa ho hasana ka metsing le ho etsa hore li kopane ka har'a liforomo.
4. Ts'ebetso le ts'ebetso:
Redispersible latex phofo e fana ka lisebelisoa tse 'maloa tsa bohlokoa ho thepa ea kaho, ho kenyelletsa:
Adhesion: E matlafatsa matla a maqhama, haholo-holo ho seretse le sekhomaretsi sa lithaele.
Flexibility: E ntlafatsa ho hanyetsa ho phunyeha le ho senyeha, e leng ntho ea bohlokoa bakeng sa li-membrane tse thibelang metsi le caulk.
Metsi Resistance: E fana ka tšireletso khahlanong le mongobo 'me e ntlafatsa ho tšoarella libakeng tse mongobo.
Tshebetso: E ntlafatsa ho sebetsana le litšoaneleho tsa tšebeliso ea metsoako e omileng ea motsoako.
5. Kopo:
Redispersible latex phofo e sebelisoa haholo liindastering tse fapaneng:
a.mamella:
Li-Adhesives tsa Lithaele le Li-Grouts: Ntlafatsa ho khomarela le ho feto-fetoha ha maemo ha ho kenngoa lithaele.
Exterior Insulation and Finishing Systems (EIFS): Ntlafatsa ts'ebetso ea EIFS ka ho fana ka ho feto-fetoha ha maemo le ho hanyetsa crack.
Liretse le li-plaster: Ntlafatsa matla a tlamahano, ho sebetsa le ho thibela metsi ha liretse tsa samente le lipolasetere.
Self-Leveling Compound: E ntlafatsa ho phalla le ho khomarela metsoako ea ho ipeha fatše.
b.Lipente le Liaparo:
E sebelisoa e le filimi ea pele le e tlamang ka lipente tse thehiloeng metsing le liphahlo ho ntlafatsa ho khomarela le ho tšoarella.
C. Sekhomaretsi:
E ntlafatsa ho khomarela le ho momahana mefuteng e fapaneng ea likhomaretsi, ho kenyeletsoa likhomaretsi tsa lehong le likhomaretsi tsa kaho.
6. Melemo:
Ho sebelisa phofo ea morao-rao ea latex ho na le melemo e latelang:
Thepa e ntlafetseng: E ntlafatsa thepa ea bohlokoa ea thepa ea mohaho e kang ho khomarela, ho tenyetseha le ho hanyetsa metsi.
Versatility: E loketse mefuta e mengata ea lisebelisoa ho tloha ho seretse le sekhomaretsi ho ea ho lipente le lirafshoa.
Ho bonolo ho sebetsana le eona: Joaloka phofo e omeletseng, ho bonolo ho e tsamaisa, ho e boloka le ho e tšoara, feela eketsa metsi ho qhala hape.
Botsoalle ba tikoloho: Mefuta e thehiloeng metsing e na le botsoalle ho feta mekhoa e meng e thehiloeng ho solvent.
Katleho ea Litšenyehelo: E thusa ho ntlafatsa litlolo, ho fokotsa litšenyehelo, le ho ntlafatsa ts'ebetso ea sehlahisoa.
7. Maikutlo a Bokamoso:
Mmaraka oa phofo oa latex o hahelletsoeng o lebelletsoe ho paka kholo e tsitsitseng, e susumetsoang ke nts'etsopele ea meaho e ntseng e tsoela pele, ho ata ha litoropo le tlhokahalo e ntseng e eketseha ea thepa ea kaho e sebetsang hantle.Likhatelo-pele tsa theknoloji tse reretsoeng ho ntlafatsa ts'ebetso ea sehlahisoa le ho holisa libaka tsa ts'ebeliso li kanna tsa tsamaisa katoloso ea mmaraka.Ho feta moo, tlhokomeliso e ntseng e hola ea mekhoa ea moaho e tsitsitseng e ka etsa hore ho amoheloe mekhoa e meng e se nang tikoloho, joalo ka li-latex powders tse ka sebelisoang hape.
Redispersible latex powder e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso ea thepa ea moaho liindastering tse fapaneng.Mehaho ea eona e ikhethang le ho feto-fetoha ha maemo ho etsa hore e be ea bohlokoa haholo lits'ebetsong ho tloha ho likhomaretsi tsa lithaele le seretse ho isa ho lipente le lirafshoa.Ka boqapi bo tsoelang pele le ho hatelloa ho ntseng ho eketseha ha mekhoa ea kaho e tsitsitseng, tlhokahalo ea phofo ea latex e ka sebelisoang hape e lebelletsoe ho tsoela pele ho hola, ho tsamaisa lipatlisiso le nts'etsopele sebakeng sena.
