Ndeipi mashandiro ekuita redispersible polymer poda?

Iyo mashandiro echiito che redispersible polymer powders (RPP) inosanganisira kudyidzana kwavo nemvura uye zvimwe zvikamu zvekuumbwa kwedhaka, zvichitungamira mukuvandudza mashandiro uye zvivakwa. Heino tsananguro yakadzama yemaitiro ekuita kweRPP:

1. Kupararirazve mumvura:
   • RPP yakagadzirirwa kupararira zviri nyore mumvura, ichigadzira yakagadzikana colloidal kumiswa kana mhinduro. Iyi redispersibility yakakosha pakubatanidzwa kwavo mumatope ekugadzira uye inotevera hydration.
2. Kugadzira Mafirimu:
   • Pakupararira patsva, RPP inogadzira firimu rakatetepa kana kufukidza zvakatenderedza masimende uye zvimwe zvikamu zvedhaka matrix. Iyi firimu inoita sebhainda, inosunga zvimedu pamwe chete uye inovandudza kubatana mukati medhaka.
3. Kunamatira:
   • Iyo RPP firimu inosimudzira kunamatira pakati pevhu zvinoumba (semuenzaniso, simende, aggregates) uye substrate nzvimbo (semuenzaniso, kongiri, masonry). Uku kunamatira kwakagadziridzwa kunodzivirira delamination uye kunovimbisa kubatana kwakasimba pakati pedhaka uye substrate.
4. Kuchengeta Mvura:
   • RPP ine hydrophilic zvivakwa zvinovagonesa kutora uye kuchengetedza mvura mukati medhaka matrix. Uku kuchengetwa kwemvura kwakawedzera kunowedzera hydration yezvinhu zvecementitious, zvichikonzera kushanda kuri nani, nguva yakazaruka yakawedzerwa, uye kunamira kwakavandudzwa.
5. Flexibility uye Elasticity:
   • RPP inopa kuchinjika uye elasticity kune iyo dhaka matrix, ichiita kuti irambe ichipokana nekutsemuka uye deformation. Uku kuchinjika kunobvumira dhaka kuti rigadzirise kufamba kwe substrate uye kuwedzera kwemafuta / kuputika pasina kukanganisa kutendeseka kwayo.
6. Kuvandudzwa Kwekushanda:
   • Kuvapo kweRPP kunovandudza kushanda uye kuenderana kwedhaka, zvichiita kuti zvive nyore kusanganisa, kuisa, uye kuparadzira. Uku kukwidziridzwa kushanda kunobvumira kuvharika kuri nani uye mamwe mayunifomu application, kuderedza mukana wevoids kana maburi mudhaka rakapedzwa.
7. Durability Enhancement:
   • RPP-yakagadziridzwa madhaka anoratidza kusimba kwakagadziridzwa nekuda kwekuwedzera kwavo kuramba kumamiriro ekunze, kurwisa kwemakemikari, uye abrasion. Iyo RPP firimu inoita sechidziviriro chinodzivirira, ichidzivirira dhaka kubva kune vekunze vanoshungurudza uye kuwedzera hupenyu hwayo hwesevhisi.
8. Kunodzorwa Kuburitswa kweZviwedzerwa:
   • RPP inogona kuvharidzira uye kuburitsa zvinoshandiswa zvinoshandiswa kana zvinowedzera (semuenzaniso, plasticizers, accelerators) mukati medhaka matrix. Iyi inodzorwa yekuburitsa meshini inobvumira kuita kwakaenderana uye akagadziridzwa mafomati kuti asangane nezvinodiwa zvekushandisa.

maitirwo echiito chepolymer poda anodhindwa zvakare anosanganisira kupararira kwawo mumvura, kugadzira firimu, kunamira kwekunamira, kuchengetwa kwemvura, kuvandudza kushanduka, kusimudzira kushanda, kusimbisa kusimba, uye kudzorwa kuburitswa kwezvinowedzera. Aya maitiro pamwe chete anobatsira mukuvandudzika mashandiro uye zvivakwa zveRPP-yakagadziridzwa madhaka mune akasiyana ekuvaka ekushandisa.
