Redispersible polymer powders (RDP) su ne hadaddun gaurayawan polymers da additives waɗanda ake amfani da su sosai a cikin kayan gini, musamman wajen samar da busassun turmi.Wadannan foda suna taka muhimmiyar rawa wajen inganta aiki da halaye na kayan gini daban-daban kamar su tile adhesives, grouts, mahadi masu daidaita kai da filastar siminti.
Mabuɗin abubuwan haɗin gwiwa:
Tushen polymer:
Ethylene vinyl acetate (EVA): EVA copolymer ana amfani dashi a cikin RDP saboda kyawawan kayan aikin fim, mannewa, da sassauci.Ana iya daidaita abun ciki na vinyl acetate a cikin copolymer don canza kaddarorin polymer.
Vinyl Acetate vs. Ethylene Carbonate: Dangane da takamaiman bukatun aikace-aikacen, masana'antun na iya amfani da ethylene carbonate maimakon vinyl acetate.Ethylene carbonate ya inganta juriya na ruwa da mannewa a cikin yanayin danshi.
Acrylics: Ana amfani da polymers na acrylic, gami da acrylics masu tsafta ko copolymers, don juriyar yanayinsu na musamman, dorewa, da juriya.An san su don samar da kyakkyawar mannewa zuwa nau'i-nau'i iri-iri.
Colloid mai kariya:
Hydroxypropyl methylcellulose (HPMC): HPMC colloid ne mai kariya wanda aka saba amfani dashi a cikin RDP.Yana inganta redispersibility na polymer barbashi da kuma kara habaka da overall Properties na foda.
Polyvinyl barasa (PVA): PVA wani colloid ne mai kariya wanda ke taimakawa cikin kwanciyar hankali da tarwatsa ƙwayoyin polymer.Hakanan yana taka rawa wajen sarrafa dankowar foda.
Filastik:
Dibutyl Phthalate (DBP): DBP misali ne na filastik wanda ake ƙarawa sau da yawa zuwa RDP don inganta sassauci da aiki.Yana taimakawa rage yawan zafin jiki na gilashin na polymer, yana sa shi ya fi dacewa.
filler:
Calcium Carbonate: Za a iya ƙara masu cika irin su calcium carbonate don haɓaka yawancin foda da samar da hanya mai mahimmanci don daidaita kaddarorin kamar rubutu, porosity da opacity.
Stabilizers da antioxidants:
Stabilizers: Ana amfani da waɗannan don hana lalacewar polymer yayin ajiya da sarrafawa.
Antioxidants: Antioxidants suna kare polymer daga lalatawar oxidative, yana tabbatar da tsawon rai na RDP.
Ayyukan kowane bangare:
Tushen polymer: Yana ba da kaddarorin yin fim, mannewa, sassauci da ƙarfin injin zuwa samfurin ƙarshe.
Colloid mai kariya: Haɓaka redispersibility, kwanciyar hankali da tarwatsa ƙwayoyin polymer.
Plasticizer: Yana inganta sassauci da aiki.
Fillers: Daidaita kaddarorin kamar rubutu, porosity, da rashin fahimta.
Stabilizers da antioxidants: Hana lalata polymer yayin ajiya da sarrafawa.
a ƙarshe:
Redispersible polymer foda (RDP) wani abu ne mai mahimmanci kuma mai mahimmanci a cikin kayan gini na zamani.Abubuwan sinadaran sa, gami da polymers kamar EVA ko resins na acrylic, colloid masu kariya, filastik, masu filaye, masu daidaitawa da antioxidants, an tsara su a hankali don saduwa da takamaiman buƙatun kowane aikace-aikacen.Haɗuwa da waɗannan abubuwan haɗin gwiwa yana taimakawa haɓaka redispersibility foda, ƙarfin haɗin gwiwa, sassauci da haɓaka gabaɗaya a cikin busassun turmi cakuda bushe.
