Polymer Modifiers
Mapolymer modifiers zvinhu zvinowedzerwa kumapolima kuti avandudze mashandiro avo kana kupa zvivakwa zvitsva. Kune akasiyana marudzi epolymer modifiers, anosanganisira mafirita, plasticizers, crosslinking agents, uye reactive diluents, pakati pevamwe. Imwe mhando yepolymer modifier iyo inowanzoshandiswa mukuvaka zvinhu ndeye Redispersible Polymer Powder (RDP).
Redispersible Polymer Powder (RDP) imhando yepolymer modifier iyo inoshandiswa mukuvaka zvinhu senge simende madhaka, mataira anonamira, uye ega-leveling makomisheni. Inogadzirwa nekupfapfaidza-kuomesa musanganiswa wepolymer emulsion uye inodzivirira colloid, uye inowanzobva pane vinyl acetate-ethylene (VAE) kana ethylene-vinyl acetate (EVA) copolymers.
RDP ichena, isina-inoyerera poda inogona kuparadzirwa nyore nyore mumvura. Kana yakasanganiswa nemvura uye cementitious zvinhu, inoumba yakagadzikana, inoshanduka, uye yakasimba firimu inovandudza zvinhu zvekuvaka. Mamwe mabhenefiti ekushandisa RDP sepolymer modifier anosanganisira:
- Kuvandudzwa kwekushanda: RDP inovandudza kushanda kwezvinhu zvecementitious nekudzikisa mvura yemukati nekuvandudza rheology. Izvi zvinoguma nekunamira kuri nani, kubata kuri nyore, uye kuderedzwa kutsemuka.
- Kuwedzera simba: RDP inovandudza kusimba uye kusimba kwezvinhu zvesimende nekuwedzera simba rechisungo uye kuderedza kupera. Izvi zvinoita kuti pave nechigadzirwa chakasimba uye chakasimba chekuvaka.
- Kuramba kurinani kumvura nemakemikari: RDP inovandudza kushorwa kwezvinhu zvesimende kumvura nemakemikari nekudzikisa porosity nekuvandudza kusamira. Izvi zvinoita kuti pave nechivakwa chisingapindi mvura uye chisingapindike mumakemikari.
- Kunamatira kurinani: RDP inonatsiridza kunamatira kwezvinhu zvesimende kune akasiyana ma substrates, anosanganisira kongiri, masonry, uye huni. Izvi zvinoguma nechisungo chakasimba uye chakasimba pakati pezvinhu zvekuvaka uye substrate.
RDP inoshandiswa mumhando dzakasiyana dzekuvaka, kusanganisira:
- Cementitious mortars: RDP inoshandiswa mumadhaka esimende akadai semataira anonamira, grouts, uye renders. Inovandudza kushanda, simba, uye kusimba kwezvinhu izvi, zvichikonzera kupera kuri nani uye hupenyu hurefu.
- Kuzvimisikidza komisheni: RDP inoshandiswa mukuzvimisikidza makomisheni kuvandudza kuyerera kwavo uye kuyera zvivakwa. Iyo inovandudzawo simba ravo uye kusimba, zvichikonzera kupera kuri nani.
- Gypsum-based products: RDP inoshandiswa mune gypsum-based products senge majoint compounds uye plasters. Inovandudza kushanda, simba, uye kusimba kwezvigadzirwa izvi, zvichikonzera kupera kwakapfava uye hupenyu hurefu.
- Insulating zvinhu: RDP inoshandiswa mukudzivirira zvinhu zvakaita sedhaka rinopisa uye machira. Inonatsiridza kunamatira, simba, uye kusimba kwezvishandiso izvi, zvichikonzera kuvharirwa kuri nani uye hupenyu hurefu.
Mukupedzisa, Redispersible Polymer Powder (RDP) imhando yepolymer modifier iyo inowanzoshandiswa mukuvaka zvinhu kuvandudza zvivakwa zvavo. Inovandudza kushanda, simba, uye kusimba kwezvinhu zvesimende, zvichikonzera kupera kuri nani uye hupenyu hurefu. RDP inoshandiswa mumhando dzakasiyana dzekuvaka senge simende madhaka, ega-leveling makomisheni, uye gypsum-based zvigadzirwa, pakati pezvimwe.
