Mokhoa oa ts'ebetso oa Redispersible Polymer Powder (RDP)

Redispersible Polymer Powder (RDP)ke phofo e phahameng ea molek'hule ea polymer, hangata e entsoeng ka emulsion ea polymer ka ho omisa. E na le thepa ea redispersibility ka metsing 'me e sebelisoa haholo kahong, ho roala, ho khomarela le masimo a mang. Mokhoa oa ts'ebetso oa Redispersible Polymer Powder (RDP) o finyelloa haholo-holo ka ho fetola thepa e thehiloeng ho samente, ho ntlafatsa matla a ho kopanya, le ho ntlafatsa ts'ebetso ea kaho.

1. Sebopeho sa motheo le thepa ea Redispersible Polymer Powder (RDP)

Sebopeho sa motheo sa Redispersible Polymer Powder (RDP) ke polymer emulsion, eo hangata e entsoeng ka polymerized ho tloha monomers tse kang acrylate, ethylene, le vinyl acetate. Limolek'hule tsena tsa polymer li etsa likaroloana tse ntle ka emulsion polymerization. Nakong ea ts'ebetso ea ho omisa, metsi a tlosoa ho etsa phofo ea amorphous. Liphofshoana tsena li ka qhalakanngoa hape ka metsing ho etsa li-dispersions tse tsitsitseng tsa polymer.

Litšobotsi tsa mantlha tsa Redispersible Polymer Powder (RDP) li kenyelletsa:

Ho qhibiliha ha metsi le ho fetoha hape: E ka qhalakanngoa ka potlako metsing ho etsa polymer colloid e tšoanang.

Lintho tse ntlafetseng tsa 'mele: Ka ho eketsa Redispersible Polymer Powder (RDP), matla a tlamahano, matla a tsitsitseng le ho hanyetsa ha lihlahisoa tse kang liphahlo le lirekere li ntlafatsoa haholo.

Ho hanyetsa boemo ba leholimo le khanyetso ea lik'hemik'hale: Mefuta e meng ea Redispersible Polymer Powder (RDP) e na le khanyetso e ntle khahlanong le mahlaseli a UV, ho bola ha metsi le lik'hemik'hale.

2. Mokhoa oa ts'ebetso oa Redispersible Polymer Powder (RDP) ka thepa e thehiloeng ho samente.

Matla a ntlafetseng a tlamahano Karolo ea bohlokoa e bapaloang ke Redispersible Polymer Powder (RDP) ka thepa e thehiloeng ho samente ke ho matlafatsa matla a eona a tlamahano. Tšebelisano pakeng tsa peista ea samente le tsamaiso ea ho hasana ea polymer e nolofalletsa likaroloana tsa polymer ho khomarela ka katleho holim'a likaroloana tsa samente. Ka har'a microstructure ea samente ka mor'a ho thatafala, limolek'hule tsa polymer li ntlafatsa matla a ho kopanya pakeng tsa likaroloana tsa samente ka ho sebetsa ka mahlakoreng a mabeli, ka tsela eo ho ntlafatsa matla a ho kopanya le matla a hatellang a thepa e thehiloeng ho samente.

Ho feto-fetoha ha maemo le ho hanyetsa ho phatloha Redispersible Polymer Powder (RDP) ho ka ntlafatsa ho feto-fetoha ha thepa e thehiloeng ho samente. Ha thepa e entsoeng ka samente e omisitsoe ebile e thatafalitsoe, limolek'hule tsa polymer ka har'a sekontiri sa samente li ka etsa filimi ho eketsa ho tiea ha thepa. Ka tsela ena, seretse sa samente kapa konkreite ha se na monyetla oa ho phatloha ha se tlas'a matla a kantle, e leng se ntlafatsang ho hanyetsa mapheo. Ho phaella moo, ho thehoa ha filimi ea polymer ho ka boela ha ntlafatsa ho ikamahanya le maemo a lisebelisoa tsa samente ho ea tikolohong e ka ntle (e kang liphetoho tsa mongobo, liphetoho tsa mocheso, joalo-joalo).

Ho fetola ts'ebetso ea kaho Ho eketsoa ha phofshoana ea sekhomaretsi e ka qhaloang hape ho ka ntlafatsa ts'ebetso ea kaho ea lisebelisoa tse thehiloeng ho samente. Ka mohlala, ho kenya phofo ea sekhomaretsi se ka qhalehang ka har'a seretse se omeletseng ho ka ntlafatsa haholo ts'ebetso ea sona le ho etsa hore mosebetsi oa kaho o be bonolo. Haholo-holo lits'ebetsong tse kang ho penta lerako le ho penta lithaele, metsi le ho boloka metsi a slurry lia ntlafatsoa, ​​ho qoba ho hlōleha ho kopanya ho bakoang ke ho fetoha mouoane pele ho nako.

Ho ntlafatsa ho hanyetsa metsi le ho tšoarella Ho thehoa ha filimi ea polymer ho ka thibela ho kenella ha metsi ka katleho, kahoo ho ntlafatsa ho hanyetsa metsi ha thepa. Libakeng tse ling tse mongobo kapa tse nang le metsi, ho eketsoa ha li-polymers ho ka liehisa ts'ebetso ea botsofali ea thepa e entsoeng ka samente le ho ntlafatsa ts'ebetso ea bona ea nako e telele. Ho phaella moo, boteng ba li-polymers bo ka boela ba ntlafatsa ho hanyetsa serame sa thepa, k'hemik'hale ea ho senya lik'hemik'hale, joalo-joalo, le ho eketsa nako e telele ea mohaho oa mohaho.
