He aha ka Redispersible Polymer Powders?

ʻO ka pauka polymer redispersible (RDP) he ʻano o ka pauka polymer i hiki ke hoʻopuehu hou ʻia i loko o ka wai e hana i kahi dispersion paʻa a i ʻole emulsion.He pauda maloʻo ia i hana ʻia ma ka hoʻomaloʻo ʻana i kahi emulsion polymer.Hoʻohana ʻia ʻo RDP i nā ʻano hana like ʻole, e like me ke kūkulu ʻana, nā adhesives, nā uhi, a me nā sealants.

Hoʻokumu ʻia ka RDP me nā ʻano polymers, e like me ka acrylics, polyvinyl acetate (PVA), polyvinyl alcohol (PVOH), a me styrene-butadiene (SBR).Hoʻohui pinepine ʻia nā polymers e hana i ka pauka me nā waiwai i makemake ʻia.Hoʻomaloʻo ʻia ka pauda a lilo i pauda maloʻo.Hiki ke hoʻopuehu hou ʻia ka pauka i loko o ka wai e hana i kahi dispersion paʻa a i ʻole emulsion.

Hoʻohana ʻia ʻo RDP i nā ʻano hana like ʻole, e like me ke kūkulu ʻana, nā adhesives, nā uhi, a me nā sealants.I ke kūkulu ʻia ʻana, hoʻohana ʻia ʻo RDP ma ke ʻano he mea hoʻohui i nā morta a me nā plasters.Hoʻonui ia i ka hana, adhesion, a me ka pale wai o ka mortar a i ʻole ka plaster.I nā mea hoʻopili, hoʻohana ʻia ʻo RDP e hoʻomaikaʻi i ka hoʻopili ʻana o ka mea hoʻopili i ka substrate.I loko o nā uhi, hoʻohana ʻia ʻo RDP e hoʻomaikaʻi i ke kūpaʻa wai a me ka maʻalahi o ka uhi.I nā sealants, hoʻohana ʻia ʻo RDP e hoʻomaikaʻi i ka hoʻopili a me ka maʻalahi o ka sealant.

Hoʻohana pū ʻia ʻo RDP i nā ʻano hana ʻē aʻe, e like me nā uhi pepa, nā ʻili ʻili, a me nā uhi lole.I nā uhi pepa, hoʻohana ʻia ʻo RDP e hoʻomaikaʻi i ke kūpaʻa wai a me ka ikaika o ka pepa.I nā ʻili ʻili, hoʻohana ʻia ʻo RDP e hoʻomaikaʻi i ke kūpaʻa wai a me ka maʻalahi o ka ʻili.I nā lole lole, hoʻohana ʻia ʻo RDP e hoʻomaikaʻi i ka pale wai a me ka maʻalahi o ka lole.

ʻO RDP kahi mea maʻalahi i hoʻohana ʻia i nā noi like ʻole.He pauka maloʻo ia e hiki ke hoʻopuehu hou ʻia i loko o ka wai e hana i kahi dispersion paʻa a i ʻole emulsion.Hoʻohana ʻia ʻo RDP i ke kūkulu ʻana, nā adhesives, nā uhi, a me nā sealants e hoʻomaikaʻi i ka hana, adhesion, a me ka pale wai o ka huahana.Hoʻohana pū ʻia ʻo RDP i nā ʻano noiʻi ʻē aʻe, e like me ka uhi pepa, nā ʻili ʻili, a me nā uhi lole.
