Mokhoa oa ho etsa liteko bakeng sa viscosity ea phofo ea latex e fumanehang hape

Hajoale, li-latex powder tse sebelisoang haholo lefatšeng ka bophara li kenyelletsa phofo ea vinyl acetate le ethylene copolymer powder, ethylene, vinyl chloride le vinyl laurate ternary copolymer powder, vinyl acetate, ethylene le acid e phahameng ea vinyl ester ternary copolymer phofo. Powder, liphofshoana tsena tse tharo tse ka qhaloang hape tsa polymer li laola 'maraka oohle, haholo vinyl acetate le ethylene copolymer powder VAC/E, e maemong a etelletseng pele lefats'eng la lefats'e mme e emela litšoaneleho tsa tekheniki tsa phofshoana ea polymer e ka qhaloang hape. E ntse e le tharollo e ntle ka ho fetisisa ea tekheniki ho latela boiphihlelo ba tekheniki le li-polymer tse kentsoeng phetohong ea seretse:

1. Ke e 'ngoe ea li-polymer tse sebelisoang ka ho fetisisa lefatšeng;

2. Boiphihlelo ba kopo lefapheng la kaho ke bona bo bongata ka ho fetisisa;

3. E ka kopana le thepa ea rheological e hlokoang ke seretse (ke hore, ho hahoa ho hlokahalang);

4. Resin ea polymer e nang le li-monomers tse ling e na le litšobotsi tsa lintho tse tlaase tsa organic volatile matter (VOC) le khase e tlaase e halefisang;

5. E na le litšoaneleho tsa ho hanyetsa ka matla ha UV, ho hanyetsa mocheso o motle le botsitso ba nako e telele;

6. Ho hanyetsa ho phahameng ho saponification;

7. E na le mocheso o moholo ka ho fetisisa oa phetoho ea khalase (Tg);

8. E na le kamano e batlang e le ntle haholo, e tenyetseha le thepa ea mochini;

9. Ho ba le phihlelo e telele ka ho fetisisa tlhahiso ea lik'hemik'hale ea mokhoa oa ho hlahisa lihlahisoa tsa boleng bo tsitsitseng le phihlelo ea ho boloka botsitso ba polokelo;

10. Ho bonolo haholo ho kopanya le colloid e sireletsang (polyvinyl alcohol) e nang le ts'ebetso e phahameng.

Mokhoa oa ho lemoha oa matla a tlamahano ea phofo ea latex e ka sebelisoang hape o khetholloa ka hore mokhoa oa boikemisetso ke o latelang:

1. Ntlha ea pele, nka 5g ea phofo ea latex e ka sebelisoang hape 'me ue kenye ka khalase ea ho lekanya senoelo, eketsa 10g ea metsi a hloekileng' me u hlohlelletse metsotso e 2 ho etsa hore e kopane hantle;

2. Ebe o lumella senoelo sa ho lekanya se tsoakiloeng ho ema metsotso e 3, ebe o tsosa hape metsotso e 2;

3. Ebe u sebelisa tharollo eohle ka senoelong sa ho lekanya holim'a poleiti e hloekileng ea khalase e behiloeng ka holimo;

4. Beha poleiti ea khalase ka kamoreng ea teko ea tlhahlobo ea DW100 ea mocheso o tlase oa mocheso;

5. Qetellong, e behe tlas'a boemo ba ho etsisa tikoloho ea 0 ° C bakeng sa hora ea 1, ntša poleiti ea khalase, u leke tekanyo ea ho etsa filimi, 'me u bale matla a ho kopanya a tloaelehileng a phofo ea latex e sebelisoang hape ho latela tekanyo ea ho etsa filimi. .
