Momwe mungadziwire bwino ufa wa polima (RDP)

Redispersible polymer powder (RDP) ndi chowonjezera chogwiritsidwa ntchito kwambiri cha polima chomwe chasintha gawo lazomangamanga. Zathandiza kwambiri kuti zipangizo zomangira zosiyanasiyana zikhale zolimba komanso zolimba. Komabe, kuzindikira RDP kumatha kukhala kovuta, makamaka kwa omwe sadziwa mawonekedwe ake.

Nawa maupangiri amomwe mungadziwire bwino RDP:

1. Mankhwala opangidwa

RDP ndi copolymer ya vinyl acetate ndi ethylene. Ndi polymerized kuchokera vinilu acetate, ethylene ndi monomers ena pamaso pa surfactants ndi zoteteza colloids. Kapangidwe kakemidwe ka RDP kamakhala ndi gawo lofunikira pakuchita kwake komanso machitidwe ake. Chifukwa chake, ndikofunikira kuphunzira kapangidwe kake ka RDP musanagwiritse ntchito pomanga.

2. Mbali

RDP ili ndi zina zozindikirika mosavuta. Choyamba, ndi ufa wonyezimira bwino, wopanda-woyera kapena wopepuka wachikasu. Chachiwiri, ili ndi kukula kwa tinthu tating'onoting'ono ta 5-100 microns. Chachitatu, imasungunuka m'madzi ndipo imakhala ndi zomatira zabwino.

3. Kuyika

RDP nthawi zambiri imayikidwa mu thumba la pulasitiki losindikizidwa kapena chidebe kuti chisamayamwitse chinyezi. Nthawi zambiri pamakhala chizindikiro ndi code pa phukusi lomwe limapereka chidziwitso cha mtundu, giredi ndi wopanga RDP. Ndikofunika kuyang'ana zoyikapo musanagule RDP kuti muwonetsetse kuti sizinasokonezedwe kapena kukumana ndi chinyezi.

4. Makhalidwe amachitidwe

RDP imawonetsa magwiridwe antchito angapo omwe amasiyanitsa ndi ma polima ena. Mwachitsanzo, RDP ili ndi kukana madzi abwino, kumamatira kwabwino komanso kusinthasintha. Ilinso ndi zinthu zabwino zopangira mafilimu, zomwe zimapangitsa kuti zikhale zowonjezera zowonjezera zomangira monga zomatira matailosi, grout, ndi konkriti.

5. Kugwirizana

RDP imagwirizana ndi zomangira zina monga simenti, gypsum ndi laimu. Kugwirizana kwake ndi zipangizozi kumatsimikizira kuti ntchito yomalizayo siiwonongeka. Chifukwa chake, ndikofunikira kuyesa kuyanjana kwa RDP musanagwiritse ntchito pazomangira.

Mwachidule, kuzindikira RDP kumafuna kumvetsetsa bwino za kapangidwe kake ka mankhwala, katundu wake, kuyika kwake, kagwiridwe kake, ndi kagwiridwe kake. Poyang'ana pazifukwa izi, munthu amatha kusiyanitsa mosavuta RDP ndi ma polima ena ndikuwonetsetsa kuti ikugwiritsidwa ntchito moyenera pazomangamanga.
