Ho fetisoa Polymer Polymer Powder (RDP) ke motsamaisi oa vinyl acetate le ethinene e hlahisoang ka mokhoa o omisang. Ke motsoako oa bohlokoa likolong tsa kaho, ho fana ka maikutlo a ho fetelletseng, ho feto-fetoha le maemo le ho se tšoanele lihlahisoa tsa haufi. Thetso ea lipopetso tsa polyer e rekiloeng e kenyelletsa mehato e mengata.
1. Khetho ea lintho tse tala:
Vinyl Acytate-Ethylene Copolymer: Lisebelisoa tse ka sehloohong tsa RDP ke copolymer of Vinyl acletane le ethylene. Copolymer ena o ile a khethoa ka lebaka la thepa ea eona e khang ea ho khokhola haholo le bokhoni ba ho eketsa maemo a feto-fetoha le ho ba thata ha thepa ea mafeto.
2. Emulsion polymerization:
Ts'ebetso e qala ka ho ts'oaroa ha emulsion, moo li-monomirs tsa Vinyl aclene le li-mohloa li entsoe ka mokhoa o ikhethileng boteng ba batsamaisi le basini.
Ts'ebetso ea Emu e laoloang ka botlalo e laoloa ka hloko ho fumana boima ba bokhabane bo lakatsehang, sebopeho le sebopeho sa copolymer.
3. Karabelo le copolymeriation:
Vinyl Acetate le Ethylene bacostemen baghlers ba arabela boteng ba khase ho theha copolymer.
Ts'ebetso ea li-copolymerication e bohlokoa ho fumana li-polymers tse nang le thepa e lakatsehang, ho kenyeletsa le thepa e ntle ea lifilimi le ho itšireletsa.
4. Spull o omelle:
Emulsion e etsoa kemiso ea ho omisa. Sena se kenyelletsa ho fafatsa emulsion ka phapusing e chesang, moo metsi a chesehang, a siilba ka mora likarolo tse matla tsa polymer tse hapiloeng.
Fokotsa maemo a ho omisa, joalo ka mocheso le moea, li laoloa ka hloko ho netefatsa sebopeho sa likamore tse ntle tsa phofo.
5. Phekolo ea bokaholimo:
Hangata phekolo ea bophahamo hangata e sebelisetsoa ho ntlafatsa tsitsipano ea polokelo le ts'ebeliso ea polyer "ea polymer.
Bydrophobic Adtisitives kapa li-colloids tse sirelletsang hangata li sebelisoa litlhare tsa mantlha ho thibela karohano ea mokokotlo le ho ntlafatsa ho lahla phofo ka metsing.
6. Taolo ea boleng:
Mehato ea taolo ea boleng bo matla e kenngoe ts'ebetsong eohle ea ts'ebetso. Liraka tse joalo ka ho tsamaisoa ka bongata, ho na le letsoalo la bongata, litaba tse setseng tsa bongata le mocheso oa khalase li netefatsoang ho netefatsa hore sehlahisoa se feto-fetoha.
7. Ho paka:
Phofo ea polymer ea ho qetela ea polyer e kentsoeng e kenngoa mesebetsing ea botumo ea ho thibela metsi, e leng hampe e ka ama tšebetso ea eona.
Likopo tsa polymer tse theko e tlaase:
RDP e sebelisoa mekhoeng e fapaneng ea lits'ebetso tsa kaho ho kenyelletsa meralo ea lithaele, metsoako ea boiketsetso, ea ho qetela ea ts'ebetso ea ho qetela (e sa tsotelleng.
Phofo e ntlafatsa thepa e kang ho hanyetsa ka metsing, ho feto-fetoha le metsi, ho matha le ho latela ts'ebetso ena ea moaho.
ha re phethela:
Polymer ea polyer ea polyer ea polyer e na le lisebelisoa tse fapaneng tse nang le lits'ebetso tsa bohlokoa indastering ea kaho. Tlhahiso ea eona e kenyelletsa ho khetha thepa e tala, emusion ea polymeriation, e fafatsa kalafo, bokahohle ea boleng ba boleng bo holimo.
Theol ea polyer ea polyer e khutlisoang ke mokhoa o rarahaneng o hlokang ho nepahala ebile o tsepamisitse maikutlo ho fumana sehlahisoa se phahameng se hlokahalang bakeng sa lits'ebetso tsa kaho.
