Ndezvipi zvimiro zvedhaka zvinogona redispersible polymer poda kuvandudza?

Redispersible polymer poda (RPP) inowanzo shandiswa mukugadzira dhaka kusimudzira akasiyana zvivakwa uye maitiro ekuita.Heano mamwe eakakosha zvivakwa zvedhaka izvo RPP inogona kuvandudza:

1. Adhesion: RPP inonatsiridza kunamatira kwedhaka kune substrates senge kongiri, masonry, huni, uye simbi.Uku kunamatira kwakakwidziridzwa kunobatsira kudzivirira delamination uye kunovimbisa hukama hwakasimba pakati pedhaka uye substrate.
2. Flexural Strength: Kubatanidza RPP mune dhaka maumbirwo anogona kuwedzera flexural simba, zvichiita kuti dhaka rirambe richipokana nekutsemuka uye deformation.Izvi zvinonyanya kukosha mumashandisirwo apo iyo substrate inogona kusangana nekufamba kana kuwedzera kwekupisa uye kuputika.
3. Kuchengetedzwa Kwemvura: RPP inosimudzira kuchengetedza kwemvura zvivakwa zvedhaka, zvichibvumira kwenguva refu hydration yezvinhu simende.Izvi zvinoguma nekushanda kuri nani, nguva yakawedzerwa yakavhurika, uye kunamira kwakagadziridzwa, kunyanya mumamiriro ekupisa kana mhepo.
4. Kushanda: RPP inovandudza kushanda uye kuenderana kwedhaka, zvichiita kuti zvive nyore kusanganisa, kuisa, uye kuparadzira.Izvi zvinobvumira kuvharika kuri nani uye kuwedzera yunifomu application, kuderedza mukana wevoids kana maburi mudhaka rakapedzwa.
5. Yakaderedzwa Shrinkage uye Kutsemuka: Nekuvandudza kunamatira, kuchinjika, uye kuchengetedza mvura, RPPs inobatsira kuderedza shrinkage uye kuputika mudhaka.Izvi zvinonyanya kubatsira mumashandisirwo apo shrinkage mitswe inogona kukanganisa kutendeseka uye kusimba kwedhaka.
6. Durability: Kushandiswa kweRPP kunogona kuwedzera kusimba kwedhaka nekuwedzera kuramba kwayo kumamiriro ekunze, kurwisa kwemakemikari, uye abrasion.Izvi zvinoguma nedhaka rinogara kwenguva refu rinochengetedza kutendeseka kwayo kwemaitiro nekufamba kwenguva.
7. Thermal uye Moisture Resistance: RPP inogona kuvandudza kupisa uye kunyorova kuramba kwedhaka, zvichiita kuti ive yakakodzera kushandiswa munzvimbo dzakasiyana siyana dzezvakatipoteredza, kusanganisira kutonhora-kunyorova kutenderera, humidity yakanyanya, uye kushanduka kwekushisa.
8. Bond Strength: RPP inobatsira pakusimba kwechisungo chedhaka, kuve nechokwadi chekunamatira kwakasimba pakati pematanho ega ega uye pakati pevhu uye substrate.Izvi zvinokosha pakuwana magungano ekuvaka akavimbika uye anogara kwenguva refu.

kuisirwa kwehupfu hwepolymer hupfu muhupfu hwedhaka kunopa zvikomborero zvakawanda, zvinosanganisira kunamira zvakanaka, kusimba kwesimba, kuchengetedza mvura, kushanda nesimba, kusimba, uye kuramba kuderera, kuputika, uye zvakatipoteredza.Izvi zvinowedzeredzwa zvinoita kuti RPP-yakagadziridzwa madhaka akakodzera kune akasiyana siyana ekuvaka maapplication, anosanganisira kuisa mataira, stucco uye plastering, kugadzirisa uye kudzoreredza, uye kudzivirira mvura.
