Redispersible polymer powder (RDP) ke motsoako oa thepa ea mohaho o fetolang emulsion ea polymer hore e be phofo ka mokhoa oa ho omisa. Ha phofo ena e kopantsoe le metsi, e ka qhalakanngoa hape ho theha latex suspension e tsitsitseng e bontšang thepa e tšoanang le latex ea pele. Boitsebiso bona bo 'nile ba sebelisoa haholo indastering ea kaho, haholo-holo ha ho etsoa seretse se omeletseng le li-adhesives tsa mohaho.
1. Lisebelisoa tsa motheo le mokhoa oa ho lokisetsa
Metsoako ea mantlha ea phofo ea latex e ka qhaloang hangata e kenyelletsa matrix a polymer, colloid e sireletsang (joalo ka joala ba polyvinyl), li-additives (joalo ka li-defoamers le li-plasticizers) le li-inorganic fillers (joalo ka calcium carbonate). Matrix a polymer ke karolo ea mantlha ea phofo ea latex e fumanehang hape. Li-polymer tse tloaelehileng li kenyelletsa ethylene-vinyl acetate copolymer (EVA), acrylate copolymer le styrene-butadiene copolymer.
Mokhoa oa ho lokisa phofo ea latex e ka sebelisoang hape e kenyelletsa mehato e latelang:
Emulsion polymerization: Ntlha ea pele, lokisetsa emulsion ea metsi e nang le polymer. Ka theknoloji ea emulsion polymerization, li-monomers li entsoe ka polymer ka metsing ho etsa likaroloana tsa emulsion tse kang polymer.
Ho omisa ka spray: Emulsion e lokiselitsoeng ea polymer e omisitsoe ka mochini o omisang spray. Emulsion e fafatsoa ka marotholi a matle 'me e omisitsoe ka potlako ho etsa likaroloana tsa phofo ea polymer.
Phekolo ea holim'a metsi: Nakong kapa ka mor'a ts'ebetso ea ho omisa, lisebelisoa tse ling tsa phekolo ea holim'a metsi (joaloka joala ba polyvinyl) hangata li eketsoa ho ntlafatsa botsitso le ho tsosolosa phofo.
2. Litšobotsi tsa ts'ebetso
Redispersible latex powder e na le lintho tse ngata tse ikhethang tse etsang hore e tuma lits'ebetsong tsa kaho:
Redispersibility: Phofo ena e ka qhalakanngoa ka metsing 'me ea khutlisetsoa boemong ba emulsion, e fana ka thepa ea thepa e tšoanang le emulsion ea pele.
Khomaretsi e ntlafalitsoeng: Ka seretse se omeletseng se omeletseng kapa sekhomaretsi, phofo ea latex e ka ntlafatsa sekhomaretsi lipakeng tsa thepa le substrate.
Ho feto-fetoha ha maemo ho ntlafetseng: E ka ntlafatsa ho feto-fetoha ha maemo le ho hanyetsa ho phatloha ha thepa le ho fokotsa kotsi ea ho phatloha ho bakoang ke khatello ea maikutlo kapa liphetoho tsa mocheso.
Ho hanyetsa metsi le ho hanyetsa boemo ba leholimo: Redispersible latex powder e ka ntlafatsa ho hanyetsa metsi le ho hanyetsa boemo ba leholimo ba thepa, ho etsa hore e be e tsitsitseng haholoanyane maemong a leholimo a mongobo kapa a fetohang.
Ho bonolo ho aha: Lisebelisoa tse nang le phofo ea latex e kentsoeng hape li na le ts'ebetso e betere nakong ea kaho, joalo ka nako e telele e bulehileng le boemo bo betere.
3. Libaka tsa kopo
Redispersible latex powder e na le mefuta e mengata ea lits'ebetso indastering ea kaho, haholoholo ho kenyelletsa lintlha tse latelang:
Sekhomaretsi sa lithaele: Phofo ea Latex e ka ntlafatsa haholo matla a tlamahano le ho feto-fetoha ha li-adhesive tsa lithaele, 'me e loketse mefuta e sa tšoaneng ea li-substrates le mefuta ea lithaele, haholo-holo mekatong ea mocheso oa mocheso le mekhoa ea ho kenya marako ka ntle.
Seretse se sa keneleng metsi: Ka mokhoa oa seretse se sa keneleng metsi, phofo ea latex e ka matlafatsa ho hanyetsa ha seretse le ts'ebetso e sa keneleng metsi ea seretse, e etsa hore e sebetse hantle libakeng tse mongobo joalo ka likamore tsa ho hlapela le li kichine.
Lisebelisoa tsa fatše: Phofo ea Latex e ka ntlafatsa metsi le ho bata ha thepa ea fatše e ikemetseng, ho etsa bonnete ba hore fatše o boreleli, o matla ebile ha ho bonolo ho petsoha ka mor'a ho haha.
Sistimi ea ho kenya lebota ka ntle: Lits'ebetsong tsa kantle tsa lebota la kantle (tse kang ho koala lerako la kantle le lits'ebetso tsa kahare), phofo ea latex e ka ntlafatsa matla a tlamahano lipakeng tsa boto ea boto le lera la motheo, ho netefatsa ho ts'epahala le ho tšoarella ha sistimi ea ho pata.
Seretse sa ho lokisa: Phofo ea Latex e phetha karolo ea ho matlafatsa maqhama le ho hanyetsa ho phunyeha ha seretse sa ho lokisa, ho netefatsa motsoako o motle oa sebaka sa ho lokisa le sebopeho sa pele le ho lelefatsa bophelo ba tšebeletso ea mohaho.
4. Tšireletso le ts'ireletso ea tikoloho
Ka ntlafatso ea tlhokomeliso ea tikoloho, litšoaneleho tsa ts'ireletso ea tikoloho ea phofo ea latex e ka sebelisoang hape e lebisitsoe tlhokomelo ho eona. Baetsi ba bangata ba amohela mekhoa ea tlhahiso ea tikoloho ho fokotsa tšebeliso ea lintho tse kotsi, 'me thepa ena e ka fokotsa litšila le ho ntlafatsa katleho ea tšebeliso ea lisebelisoa lits'ebetsong tsa kaho. Ho phaella moo, ha ho ntse ho ntlafatsa ts'ebetso ea thepa ea mohaho, phofo ea latex e ka boela ea fokotsa litšenyehelo tsa tlhokomelo le tšebeliso ea matla ea mehaho, kahoo e kenya letsoho ntlafatsong ea mehaho e tsitsitseng.
5. Litebello tsa 'maraka le mekhoa ea ntlafatso
Ka tlhokahalo e ntseng e eketseha ea lisebelisoa tse sebetsang hantle le tse sireletsang tikoloho indastering ea kaho, litebello tsa 'maraka tsa phofshoana ea latex e ka sebelisoang hape li pharaletse. Mekhoa ea ntlafatso ea nako e tlang e kenyelletsa:
Ntlafatso ea ts'ebetso: Tsoela pele ho ntlafatsa ts'ebetso ea phofo ea latex, joalo ka ho ntlafatsa khanyetso ea boemo ba leholimo le khanyetso ea lik'hemik'hale, ho fihlela litlhoko tsa maemo a fapaneng a ts'ebeliso.
Tlhahiso e tala: Fokotsa khase ea khabone le phello ea tikoloho ea ts'ebetso ea tlhahiso ka k'hemistri e tala le mekhoa e tsitsitseng.
Lihlahisoa tse ikhethileng: Fana ka lihlahisoa tsa phofo tsa latex ho latela litlhoko tse ikhethileng tsa bareki ho ikamahanya le maemo a ikhethileng a ts'ebeliso, joalo ka kaho ea mocheso o tlase, tikoloho ea mongobo o phahameng, jj.
Redispersible latex powder, e le motsoako oa bohlokoa oa thepa ea mohaho, o na le menyetla e mengata ea kopo. Ts'ebetso ea eona e babatsehang ha e ntlafatse feela boleng ba thepa ea mohaho, empa e boetse e khothalletsa indasteri ea kaho hore e ntlafatse ka tsela e tsitsitseng ea tikoloho le e tsitsitseng.
