Phofo ea polymer e qhalakantsoeng hape (RDP) ke metsoako e rarahaneng ea li-polymer le li-additives tse sebelisoang haholo thepa ea kaho, haholo-holo tlhahisong ea li-dry-mix mortars. Phofo ena e bapala karolo ea bohlokoa ho ntlafatseng ts'ebetso le litšobotsi tsa thepa e fapaneng ea kaho joalo ka likhomaretsi tsa thaele, li-grout, metsoako e ikamahanyang le maemo le li-plaster tsa samente.
Likarolo tsa bohlokoa:
Motheo oa polymer:
Ethylene vinyl acetate (EVA): Copolymer ea EVA e sebelisoa hangata ho RDP ka lebaka la thepa ea eona e ntle ea ho etsa filimi, ho khomarela le ho tenyetseha. Sekhahla sa acetate ea vinyl ka har'a copolymer se ka fetoloa ho fetola thepa ea polymer.
Vinyl Acetate khahlanong le Ethylene Carbonate: Ho latela litlhoko tse itseng tsa ts'ebeliso, bahlahisi ba ka sebelisa ethylene carbonate ho fapana le vinyl acetate. Ethylene carbonate e na le khanyetso e ntlafetseng ea metsi le ho khomarela maemong a mongobo.
Li-acrylic: Li-polymer tsa acrylic, ho kenyeletsoa le li-acrylic tse hloekileng kapa li-copolymer, li sebelisoa ka lebaka la ho hanyetsa boemo ba leholimo ka tsela e ikhethang, ho tšoarella le ho tenyetseha. Li tsebahala ka ho fana ka ho khomarela hantle mefuta e fapaneng ea li-substrate.
Colloid e sireletsang:
Hydroxypropyl methylcellulose (HPMC): HPMC ke colloid e sireletsang e sebelisoang haholo ho RDP. E ntlafatsa ho qhalana ha likaroloana tsa polymer le ho ntlafatsa thepa eohle ea phofo.
Polivinyl alcohol (PVA): PVA ke colloid e 'ngoe e sireletsang e thusang ho tsitsisa le ho hasana ha likaroloana tsa polymer. E boetse e bapala karolo ea ho laola ho teteana ha phofo.
Setlolo sa polasetiki:
Dibutyl Phthalate (DBP): DBP ke mohlala oa plasticizer e atisang ho eketsoa ho RDP ho ntlafatsa ho tenyetseha le ho sebetsa habonolo. E thusa ho fokotsa mocheso oa phetoho ea khalase ea polymer, e leng se etsang hore e tenyetsehe haholoanyane.
setlatsetso:
Calcium Carbonate: Li-filler tse kang calcium carbonate li ka eketsoa ho ntlafatsa boholo ba phofo le ho fana ka mokhoa o theko e tlaase oa ho fetola litšobotsi tse kang sebopeho, masoba le ho se bonahale hantle.
Li-stabilizer le li-antioxidants:
Li-stabilizer: Tsena li sebelisetsoa ho thibela ho senyeha ha polymer nakong ea polokelo le ts'ebetso.
Li-antioxidants: Li-antioxidants li sireletsa polymer hore e se ke ea senyeha ka lebaka la oxidative, e leng se netefatsang hore RDP e tla phela nako e telele.
Mesebetsi ea karolo ka 'ngoe:
Motheo oa polymer: E fana ka thepa ea ho etsa filimi, ho khomarela, ho tenyetseha le matla a mechini sehlahisoa sa ho qetela.
Colloid e sireletsang: E ntlafatsa ho qhalana hape, botsitso le ho hasana ha likaroloana tsa polymer.
Plasticizer: E ntlafatsa ho tenyetseha le ho sebetsa habonolo.
Li-Filler: Fetola litšobotsi tse kang sebopeho, masoba le ho se bonahale hantle.
Li-stabilizer le li-antioxidants: Li thibela ho senyeha ha polymer nakong ea polokelo le ts'ebetso.
ha re phethela:
Phofo ea polymer e qhalakantsoeng hape (RDP) ke motsoako o feto-fetohang le oa bohlokoa thepa ea sejoale-joale ea kaho. Sebopeho sa eona sa lik'hemik'hale, ho kenyeletsoa le li-polymer tse kang EVA kapa li-resin tsa acrylic, li-colloid tse sireletsang, li-plasticizer, li-filler, li-stabilizer le li-antioxidants, li entsoe ka hloko ho fihlela litlhoko tse ikhethileng tsa ts'ebeliso e 'ngoe le e 'ngoe. Motsoako oa likarolo tsena o thusa ho ntlafatsa ho qhala hape ha phofo, matla a tlamahano, ho tenyetseha le ts'ebetso e akaretsang mefuteng ea seretse se omileng.
