Redispersible polymer poda (RDP) inoshandiswa zvakanyanya polymer yekuwedzera iyo yakashandura munda wezvivakwa zvekuvaka.Yakaita basa rakakosha mukuvandudza kunaka nekusimba kwezvinhu zvakasiyana siyana zvekuvaka.Nekudaro, kuziva RDP kunogona kunetsa, kunyanya kune avo vasina kujairana nemaitiro ayo.
Heano mamwe matipi ekuti unganyatso ziva sei RDP:
1. Kuumbwa kwemakemikari
RDP ndeye copolymer yevinyl acetate uye ethylene.Iyo polymerized kubva kuvinyl acetate, ethylene uye mamwe mamonomers muhupo hweva surfactants uye inodzivirira colloids.Iyo kemikari inoumbwa yeRDP inoita basa rakakosha mukuita kwayo uye maitiro.Naizvozvo, zvakakosha kuti uverenge kemikari yeRDP usati waishandisa mune zvekuvaka.
2. Zvimiro
RDP ine zvimwe zvinoonekwa zviri nyore.Chekutanga, ivhu rakanaka chena, chena-chena kana chiedza yellow powder.Chechipiri, ine particle size range ye5-100 microns.Chechitatu, inonyungudika mumvura uye ine zvinhu zvakanaka zvekunamira.
3. Packaging
RDP inowanzoiswa mubhegi repurasitiki rakavharwa kana mudziyo kudzivirira kunyura.Pane kazhinji pane label uye kodhi pasuru inopa ruzivo nezve rudzi, giredhi uye mugadziri weRDP.Izvo zvakakosha kuti utarise kurongedza usati watenga RDP kuti uone kuti haina kukanganiswa kana kuratidzwa nehunyoro.
4. Maitiro ekuita
RDP inoratidza akati wandei maitiro anoisiyanisa kubva kune mamwe mapolymer.Semuenzaniso, RDP ine mvura yakanaka kuramba, yakanakisa kunamatira uye kuchinjika.Iyo zvakare ine yakanaka yekugadzira firimu zvimiro, izvo zvinoita kuti ive yakanakira yekuwedzera yekuvaka senge mataira anonamira, grout, uye kongiri.
5. Kugarisana
RDP inowirirana nezvimwe zvekuvaka zvakaita sesimende, gypsum uye lime.Kuwirirana kwayo nezvinhu izvi kunovimbisa kuti kushanda kwechigadzirwa chekupedzisira hakusi kukanganisa.Naizvozvo, zvakakosha kuti uedze kuenderana kweRDP usati waishandisa mune zvekuvaka.
Muchidimbu, kuziva RDP kunoda kunzwisisa kwekutanga kwemakemikari ayo, zvivakwa, kurongedza, kuita, uye kuenderana.Nekutarisa pazvinhu izvi, munhu anogona kusiyanisa zviri nyore RDP kubva kune mamwe mapolymer uye kuona kushandiswa kwayo kwakaringana mukuvaka zvinhu.
