Yadda ake gwada foda mai sake rarrabawa na polymer RDP?

Hanyar gwaji don kaddarorin da danko na foda polymer mai sake fashewa RDP, Ana amfani da shi sosai a duk duniya don watsa foda polymer RDP tare da vinyl acetate da foda emulsion mai sake fashewa, ethylene da vinyl chloride da lauric acid vinyl ester ternary copolymer foda, vinyl acetate da ethylene da senior fatty acid vinyl ester ternary copolymer foda, waɗannan ukun don watsa foda polymer RDP a cikin kasuwa gaba ɗaya, musamman vinyl acetate da ethylene copolymer foda VAC/E. Yana da matsayi na gaba a fagen duniya kuma yana wakiltar halayen fasaha na foda polymer mai sake fashewa RDP.

Foda mai sake wargazawa ta polymerRDP yana da ƙarfin haɗin gwiwa mai ban mamaki, yana inganta sassaucin turmi kuma yana da tsawon lokacin buɗewa, yana ba turmi juriya mai kyau ga alkaline, yana inganta mannewar turmi, ƙarfin lanƙwasa, hana ruwa shiga, filastik, juriya ga lalacewa da gini, a cikin turmi mai sassauƙa yana da sassauci mai ƙarfi.

Daga ƙwarewar fasaha ta polymer da aka gyara ta turmi, har yanzu mafita ce mafi kyau ta fasaha:

1, RDP yana ɗaya daga cikin polymers da aka fi amfani da su a duniya.
2, Kwarewa mai zurfi a fannin amfani da gine-gine;

3, zai iya biyan buƙatun kaddarorin rheological na turmi (wato, ginin da ake buƙata);

4, tare da sauran monomer polymer resin yana da ƙarancin ƙwayoyin halitta masu canzawa (VOC) da ƙarancin halayen iskar gas mai ban haushi;

5, tare da kyakkyawan juriyar UV da kyakkyawan juriyar zafi da kwanciyar hankali na dogon lokaci;

6, tare da juriya mai ƙarfi ga saponification;

7, tare da kewayon zafin gilashi mai faɗi (Tg);

8, tare da kyakkyawan haɗin kai, sassauci da kuma halayen injiniya;

9, aiki mai sauƙi da kama da na haɗin colloid mai kariya (polyvinyl alcohol).

Hanyar gano ƙarfin manne na foda polymer mai sake wargazawa RDP tana da alaƙa da waɗannan hanyoyin tantancewa:

1, da farko a zuba foda polymer mai sake narkewa RDP 5g a cikin kofin auna gilashi, a zuba ruwa mai tsarki 10g a gauraya na tsawon minti 2, a gauraya shi daidai gwargwado;

2. Sai a saita kofin aunawa na minti 3 sannan a sake juyawa na minti 2;

3. A shafa dukkan ruwan da ke cikin kofin aunawa a kan farantin gilashi mai tsabta a kwance;

4, sanya farantin gilashin a cikin akwatin gwajin kwaikwayon yanayin zafi mai ƙarancin zafi na DW100;

5, a ƙarshe an sanya shi a cikin yanayin kwaikwayon muhalli na 0°C na tsawon awa 1, cire farantin gilashin, gwada ƙimar samuwar fim ɗin, bisa ga canjin ƙimar samuwar fim ɗin na foda polymer mai sake wargazawa RDP ta amfani da ƙarfin haɗin gwiwa na yau da kullun.
