Indlela yokuvavanya i-viscosity ye-latex powder ephindwe kabini

Okwangoku, i-latex powders esetyenziswa ngokubanzi emhlabeni ibandakanya i-vinyl acetate kunye ne-ethylene copolymer powder, i-ethylene, i-vinyl chloride kunye ne-vinyl laurate ternary copolymer powder, i-vinyl acetate, i-ethylene kunye ne-fatty acid ephezulu ye-vinyl ester ternary copolymer powder. Umgubo, ezi zithathu zepolymer zomgubo zilawula imarike yonke, ngakumbi i-vinyl acetate kunye ne-ethylene copolymer powder VAC/E, ethatha indawo ephambili kwibala lehlabathi kwaye imele iimpawu zobugcisa zomgubo wepolymer ophinda uhlakazwe. Isesona sisombululo sihle sobuchwephesha ngokwamava obugcisa kunye neepolymers ezisetyenziswa kuhlengahlengiso lodaka:

1. Yenye yeepolima ezisetyenziswa kakhulu ehlabathini;

2. Amava esicelo kwintsimi yolwakhiwo ngowona mkhulu;

3. Iyakwazi ukuhlangabezana neempawu ze-rheological ezifunwa ngudaka (oko kukuthi, ukwakhiwa okufunekayo);

4. I-resin ye-polymer kunye namanye ama-monomers aneempawu ze-organic volatile matter (VOC) kunye negesi ephantsi enomsindo;

5. Ineempawu zokumelana ne-UV ebalaseleyo, ukumelana nobushushu obuhle kunye nokuzinza kwexesha elide;

6. Ukuchasa okuphezulu kwi-saponification;

7. Inolona luhlu lubanzi lotshintsho lweglasi (Tg);

8. Inobambiso olugqwesileyo olubanzi, ukuguquguquka kunye neempawu zoomatshini;

9. Yiba nelona xesha lide kwimveliso yeekhemikhali zendlela yokuvelisa iimveliso ezisemgangathweni ezizinzile kunye namava ekugcineni uzinzo lokugcina;

10. Kulula kakhulu ukudibanisa ne-colloid yokukhusela (i-polyvinyl alcohol) kunye nokusebenza okuphezulu.

Indlela yokufumanisa amandla okubopha i-latex powder edispersible ibonakaliswe ukuba indlela yokumisela ilandelayo:

1. Okokuqala, thabatha i-5g ye-latex powder ephinda iphindwe kwaye uyibeke kwiglasi yokulinganisa indebe, yongeza i-10g yamanzi acocekileyo kwaye ugxobhoze imizuzu emi-2 ukuze udibanise ngokulinganayo;

2. Emva koko vumela indebe yokulinganisa edibeneyo ime imizuzu emi-3, uze uvuselele kwakhona imizuzu emi-2;

3. Emva koko sebenzisa sonke isisombululo kwikomityi yokulinganisa kwi-plate yeglasi ecocekileyo ebekwe ngokuthe tye;

4. Beka ipleyiti yeglasi kwi-DW100 yegumbi lovavanyo lokulinganisa lobushushu obuphantsi;

5. Ekugqibeleni, yibeke phantsi kwemeko yokulinganisa okusingqongileyo ye-0 ° C ngeyure le-1, thabatha iplate yeglasi, uvavanye ireyithi yokwenza ifilimu, kwaye ubale amandla okudibanisa okusemgangathweni kwe-latex powder edibeneyo esetyenziswayo ngokuhambelana nesantya sokwenza ifilimu. .
