Yadda za a gwada redispersible polymer foda RDP?

Hanyar gwaji don kaddarorin da danko na redispersible polymer foda RDP, A duk duniya ana amfani da ko'ina don tarwatsa polymer foda RDP tare da vinyl acetate da ethylene copolymerized emulsion foda, ethylene da vinyl chloride da lauric acid vinyl ester ternary copolymer foda, vinyl acetate da ethylene m acid vinyl ester ternary copolymer foda, waɗannan uku don tarwatsa polymer foda RDP a cikin duk kasuwar mamaye, musamman vinyl acetate da ethylene copolymer foda VAC / E, Ya mamaye babban matsayi a fagen duniya kuma yana wakiltar halayen fasaha na redispersible polymer foda RDP .

Redispersible polymer fodaRDP yana da ingantaccen ƙarfin haɗin gwiwa, haɓaka sassaucin turmi kuma yana da lokacin buɗewa mai tsayi, ba da turmi kyakkyawan juriya na alkaline, haɓaka mannewar turmi, ƙarfin sassauƙa, mai hana ruwa, filastik, juriya da gini, a cikin turmi mai sassauƙa mai tsauri. yana da sassauci mai ƙarfi.

Daga ƙwarewar fasaha na polymer wanda aka gyara ta turmi, har yanzu shine mafi kyawun maganin fasaha:

1, RDP yana ɗaya daga cikin polymers da aka fi amfani dashi a duniya.
2, Experiencewarewar ƙwarewar aikace-aikacen a fagen gine-gine;

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

4, tare da sauran monomer polymer guduro yana da ƙananan kwayoyin maras tabbas (VOC) da ƙananan halayen iskar gas;

5, tare da kyakkyawan juriya na uv da kyakkyawan juriya na zafi da kwanciyar hankali na dogon lokaci;

6, tare da babban juriya na saponification;

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

8, tare da in mun gwada da kyau kwarai m bonding, sassauci da inji Properties;

9, aiki mai sauƙi da makamancin haka na haɗin colloid mai kariya (polyvinyl barasa).

Hanyar ganowa don ƙarfin mannewa na redispersible polymer foda RDP yana da alaƙa da hanyoyin ƙaddara masu zuwa:

1, da farko ɗauki redispersible polymer foda RDP 5g a cikin gilashin auna kofin, ƙara 10g tsarki ruwa da motsawa na 2min, sa shi ko'ina gauraye;

2. Saita gauraye kofin na tsawon minti 3 kuma a sake motsawa na 2min;

3. Shafe duk bayani a cikin ma'auni a kan farantin gilashi mai tsabta a kwance;

4, sanya gilashin farantin cikin DW100 ƙananan zafin jiki na yanayin simintin gwaji;

5, a ƙarshe sanya a cikin 0 ° C yanayi kwaikwaiyo muhalli na 1 hour, fitar da gilashin farantin, gwada fim samuwar kudi, bisa ga fim samuwar kudi tuba na redispersible polymer foda RDP a yin amfani da daidaitattun bonding ƙarfi.
