Mokhoa oa ho leka RDP ea phofo ea polymer e ka qhalanngoang hape?

Mokhoa oa teko bakeng sa thepa le ho hlaka ha phofo ea polymer e ka qhalanngoang hape, Lefatšeng ka bophara e sebelisoa haholo ho hasanya phofo ea polymer RDP ka phofo ea vinyl acetate le ethylene copolymerized emulsion, ethylene le vinyl chloride le lauric acid vinyl ester ternary copolymer powder, vinyl acetate le ethylene le senior fatty acid vinyl ester ternary copolymer powder, tsena tse tharo ho hasanya phofo ea polymer RDP 'marakeng oohle, haholo-holo vinyl acetate le ethylene copolymer powder VAC/E, E na le boemo bo etellang pele lefapheng la lefats'e mme e emela litšobotsi tsa tekheniki tsa phofo ea polymer e ka qhalanngoang hape RDP.

Phofo ea polymer e ka qhaloang hapeRDP e na le matla a matle a tlamo, e ntlafatsa ho tenyetseha ha seretse mme e na le nako e telele ea ho bula, e fa seretse khanyetso e ntle ea alkaline, e ntlafatsa ho khomarela ha seretse, matla a ho tenyetseha, ho se kenelle metsi, polasetiki, khanyetso ea ho tsofala le kaho, seretseng se tenyetsehang se loantšang mapetso se na le ho tenyetseha ho matla.

Ho tsoa phihlelong ea botekgeniki ea polymer e fetotsoeng ke seretse, e ntse e le tharollo e betere ea botekgeniki:

1, RDP ke e 'ngoe ea li-polymer tse sebelisoang haholo lefatšeng.
2, Phihlelo e pharaletseng ea ts'ebeliso lefapheng la meralo ea kaho;

3, e ka fihlela litlhoko tsa thepa ea rheological ea seretse (ke hore, kaho e hlokahalang);

4, hammoho le resin e 'ngoe ea polymer ea monomer e na le lintho tse fokolang tsa tlhaho tse feto-fetohang (VOC) le litšobotsi tse tlase tsa khase e halefisang;

5, e nang le khanyetso e ntle ea mahlaseli a kotsi a letsatsi le mocheso o motle le botsitso ba nako e telele;

6, e nang le khanyetso e phahameng ea saponification;

7, e nang le mocheso o pharaletseng oa khalase (Tg);

8, e nang le kamano e pharaletseng e babatsehang, ho tenyetseha le thepa ea mechini;

9, tshebetso e bonolo le e tshwanang ya motswako wa colloid e sireletsang (polyvinyl alcohol).

Mokhoa oa ho lemoha matla a sekhomaretsi a phofo ea polymer e qhalakanngoang hape ea RDP o khetholloa ka mekhoa e latelang ea ho fumana:

1, qala ka ho nka phofo ea polymer e qhalakantsoeng hape ea RDP 5g ka koping ea ho lekanya ea khalase, eketsa 10g ea metsi a hloekileng 'me u hlohlelletse metsotso e 2, u etse hore e tsoakane ka ho lekana;

2. Beha kopi e kopaneng ea ho lekanya metsotso e 3 ebe u hlohlelletsa hape metsotso e 2;

3. Tlotsa tharollo eohle ka koping ea ho lekanya holim'a poleiti e hloekileng ea khalase e bataletseng;

4, kenya poleiti ea khalase ka lebokoseng la teko ea ketsiso ea tikoloho ea mocheso o tlase oa DW100;

5, qetellong e beoa maemong a ketsiso ea tikoloho ea 0°C ka hora e le 'ngoe, ntša poleiti ea khalase, leka sekhahla sa ho thehoa ha filimi, ho latela phetoho ea sekhahla sa ho thehoa ha filimi ea phofo ea polymer e qhalakanngoang hape ea RDP ts'ebelisong ea matla a tloaelehileng a ho kopanya.
