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 ka uhi ʻana, hoʻohana ʻia ʻo RDP e hoʻomaikaʻi i ka pale 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, adhesives, coatings, a me sealants e hoʻomaikaʻi i ka hana, adhesion, a me ka pale wai o ka huahana. 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.
