Redispersible polymer foda (RDP) copolymer ne na vinyl acetate da ethylene da aka samar ta hanyar bushewar bushewa. Abu ne mai mahimmanci a cikin aikace-aikacen gini iri-iri, yana samar da mafi kyawun mannewa, sassauci da karko ga samfuran tushen siminti. Ƙirƙirar foda na polymer da za a iya rarrabawa ya ƙunshi matakai da yawa.
1. Zaɓin ɗanyen abu:
Vinyl acetate-ethylene copolymer: Babban albarkatun kasa na RDP shine copolymer na vinyl acetate da ethylene. An zaɓi wannan copolymer don kyawawan kaddarorin sa na mannewa da iyawar ƙara sassauci da taurin kayan siminti.
2. Emulsion polymerization:
Tsarin samarwa ya fara ne tare da emulsion polymerization, wanda vinyl acetate da ethylene monomers aka polymerized a gaban initiators da stabilizers.
Ana sarrafa tsarin emulsion polymerization a hankali don samun nauyin kwayoyin da ake so, abun da ke ciki, da tsarin copolymer.
3. Reaction da copolymerization:
Vinyl acetate da ethylene monomers suna amsawa a gaban mai kara kuzari don samar da copolymer.
Tsarin copolymerization yana da mahimmanci don samun polymers tare da kaddarorin da ake so, gami da kyawawan kaddarorin yin fim da sakewa.
4. Fesa bushewa:
A emulsion ne sa'an nan hõre wani feshi bushewa tsari. Wannan ya haɗa da fesa emulsion a cikin ɗaki mai zafi, inda ruwa ke ƙafe, yana barin barbashi mai ƙarfi na polymer redispersible.
Yanayin bushewar fesa, kamar zafin jiki da kwararar iska, ana sarrafa su a hankali don tabbatar da samuwar barbashi mai kyau na foda mai gudana kyauta.
5. Maganin saman:
Sau da yawa ana amfani da jiyya na saman don haɓaka kwanciyar hankali da sake rarrabuwar foda na polymer.
Hydrophobic Additives ko m colloid ana amfani da su sau da yawa a saman jiyya don hana barbashi agglomeration da kuma bunkasa foda watsawa a cikin ruwa.
6. Kula da inganci:
Ana aiwatar da tsauraran matakan kula da inganci a cikin tsarin masana'antu. Ana kula da ma'auni kamar rarraba girman barbashi, yawan yawa, saura monomer abun ciki da zafin canjin gilashi don tabbatar da daidaiton samfur.
7. Marufi:
Ana tattara foda na ƙarshe da za'a iya rarrabawa a cikin kwantena masu tabbatar da danshi don hana sha ruwa, wanda zai iya yin mummunan tasiri akan aikin sa.
Aikace-aikace na Foda na Polymer Redispersible:
Ana amfani da RDP a cikin nau'ikan aikace-aikacen gini da suka haɗa da tile adhesives, mahadi masu daidaita kai, tsarin karewa na waje (EIFS) da turmi siminti.
Foda yana haɓaka kaddarorin irin su juriya na ruwa, sassauci da mannewa, yana taimakawa haɓaka aikin gabaɗaya da ƙarfin waɗannan kayan gini.
a ƙarshe:
Redispersible polymer foda abu ne mai mahimmanci tare da aikace-aikace masu mahimmanci a cikin masana'antar gine-gine. Samarwarsa ya haɗa da zaɓin hankali na kayan albarkatun ƙasa, emulsion polymerization, bushewar feshi, jiyya na ƙasa da tsauraran matakan kulawa.
Ƙirƙirar foda na polymer da za a sake tarwatsawa shine tsari mai rikitarwa wanda ke buƙatar daidaito da hankali ga daki-daki don samun samfur mai inganci tare da kaddarorin da ake buƙata don aikace-aikacen gini.
