Wobwezeretsedwa polima ufa (RDP) ndi wopopera wa vinyl acetate ndi ma ethylene omwe adapangidwa kudzera munjira yowuma. Ndizofunikira kwambiri pakupanga zomangamanga, kupereka zomatira bwino, kusinthasintha ndi kulimba kwa zinthu za simenti. Kupanga ufa wobwezeretsa polima kumaphatikizapo njira zingapo.
1. Kusankhidwa kwazinthu:
Vinyl acetate-ethylene Copolymer: Zopangira zazikulu za RDP ndi wopopera wa vinyl acetate ndi ethylene. Coptolimer iyi idasankhidwa kukhala chinthu chake chabwino kwambiri komanso kuthekera kowonjezera kusinthasintha komanso kulimba kwa zinthu.
2. Emulsion Polymerization:
Njira yopanga imayamba ndi emulsion polymerization, momwe ma vinyl acetate ndi ma ethylene molymer ali okhazikika polymer pamaso pa oyambitsa ndi okhazikika.
Njira ya Emulsion polymerization imayang'aniridwa mosamala kuti mupeze kulemera komwe mukufuna, kapangidwe kake, komanso kapangidwe ka porpolity.
3 ..
Vinyl acetate moomemers amatenga pampando kuti apange chopopera.
Njira ya koloko ndiyofunikira kupeza ma polima okhala ndi zokomera, kuphatikizapo katundu wabwino wopanga ndi kukonzanso.
4. Kuyanika:
Emulsion imayikidwa ndi kupukutira kupukuta. Izi zimaphatikizapo kupopera mpweya ku chipinda chotentha, pomwe madzi amatuluka, kusiya tinthu tating'onoting'ono tobwezeretsanso polima.
Kuthira malo owuma, monga kutentha ndi mpweya, kumayang'aniridwa mosamala kuti zitsimikizire mapangidwe a ufa waulere wa ufa.
5.
Njira zochizira zapamwamba nthawi zambiri zimagwiritsidwa ntchito kukonza zosunga ndikukonzanso ufa wa polima.
Zowonjezera za Hydrophobic Zowonjezera kapena zoteteza nthawi zambiri zimagwiritsidwa ntchito pomuteteza kuti tisakhale ndi tinthu tating'onoting'ono tomwe timabalalitsa m'madzi.
6. Kuwongolera kwapamwamba:
Njira zoyenera zowongolera zimakhazikitsidwa pakupanga njira yopanga. Magawo monga tinthu tating'onoting'ono, kachulukidwe kambiri, zotsalira zomwe zimachitika ndipo kutentha kwagalasi kumayang'aniridwa kuti zitsimikizike kuti zisasintha.
7..
Ufa womaliza wobwezeretsedwa polima umaphatikizidwa mu chinyezi cha chinyezi kuti mupewe kuyamwa madzi, zomwe zingasokoneze momwe akugwirira ntchito.
Mapulogalamu a ufa wobwezeretsedwanso:
RDP imagwiritsidwa ntchito popanga zomangamanga kuphatikiza ndi ma tiles, mankhwala omwe amadzipangitsa, kukonza zopindika kunja, (maphedwe a simenti).
Ufa umawonjezera katundu monga kukana madzi, kusinthasinthasintha, kuthandiza kukonza magwiridwe antchito ndi kukhazikika kwa zinthu zomanga.
Pomaliza:
Kubwezeretsa polima polima ndi zinthu zomwe zimagwiritsidwa ntchito ndi ntchito zofunikira pomanga. Kupanga kwake kumaphatikizapo kusankha mosamalitsa zida zophika, emulsion polymerization, kuyanika kwa kasiketi, mankhwalawa komanso njira zoyenera zowongolera.
Kupanga ufa wobwezeretsedwa ndi polima ndi njira yovuta yomwe imafunikira kuwongolera komanso kusamalira mwatsatanetsatane kuti mupeze zinthu zapamwamba kwambiri ndi zomwe zimafunikira pomanga.
