Ayyuka da aikace-aikacen RDP
Inganta aikin haɗin gwiwa:
RDP yana taka rawa a cikin kayan aiki, yana haɓaka mannewa na mannewa, kuma yana inganta haɗin kai tsakanin kayan gini da kayan aiki.
Wuraren aikace-aikacen sun haɗa da tile adhesives, bonding turmi, da dai sauransu.
Ingantacciyar sassauci da juriya mai tsauri: Ta hanyar ƙara RDP, haɓakar kayan aiki yana inganta sosai, wanda ke taimakawa hana faruwar fashe.
Yawanci ana amfani da su a cikin tsarin insulation, m putty, kayan gyara, da dai sauransu.
Ingantattun juriya na ruwa da juriya na ruwa:
RDP yana inganta juriya na ruwa na abu, yana ba shi damar kula da aikin kwanciyar hankali a cikin yanayi mai laushi.
Ana amfani da su a cikin suturar ruwa, kayan bango na waje, da dai sauransu.
Inganta aikin gini:
RDP na iya inganta aikin gine-gine na busassun kayan foda, yin aiki mai sauƙi da inganci.
An yi amfani da shi sosai a cikin kayan bene na kai-da-kai, sutura, da sauransu.
Ingantacciyar ƙarfin ƙarfi da juriya na yanayi: Saboda ƙari na RDP, ƙarfin ƙarfi da juriya na kayan abu sun inganta sosai, kuma yana iya jure gwajin yanayin yanayi.
Aiwatar da tsarin bango na waje, rufin rufin, da sauransu.
Abubuwan la'akari don zaɓar RDP mai dacewa
Yanayin aikace-aikacen:
Zaɓi nau'in RDP mai dacewa bisa ga takamaiman yanayin aikace-aikacen, alal misali, aikace-aikacen waje suna buƙatar RDP tare da juriya mai kyau.
Kula da farashi:
A kan yanayin tabbatar da aikin, ya zama dole a yi la'akari da farashin kayan aiki kuma zaɓi RDP na tattalin arziki.
Daidaituwa:
RDP yana buƙatar dacewa da kyau tare da sauran kayan don tabbatar da kwanciyar hankali da daidaiton aiki na cakuda.
Bukatun aiki:
Zaɓi nau'in RDP mai dacewa bisa ga kaddarorin da ake buƙata (kamar sassauci, mannewa, juriya na ruwa, da sauransu).
Redispersible latex foda yana taka muhimmiyar rawa a cikin kayan gini na zamani, kuma nau'ikansa daban-daban suna ba da mafita mai sassauƙa don buƙatun gini daban-daban. Zaɓin nau'in RDP mai dacewa zai iya inganta aikin kayan gini sosai, don haka inganta inganci da dorewa na ayyukan gine-gine.
