Re-Dispersible Emulsion Poda Yechigadzirwa chedhaka
Re-dispersible emulsion powder (RDP) chinhu chakakosha chekuwedzera chinoshandiswa mumatope ekushandisa muindasitiri yekuvaka. Iyo yemahara-inoyerera, chena poda inowanikwa nekupfapfaidza kuomesa yeaqueous vinyl acetate-ethylene copolymer dispersion. RDP inopa huwandu hwezvivakwa zvinobatsira kune dhaka, inowedzera kuita kwayo, kushanda kwayo, uye kusimba. Heano mashandisirwo eRDP mumatope ekunyorera:
1. Kuvandudza Kunamatira:
- RDP inosimudzira zvakanyanya kunamatira kwedhaka kune akasiyana substrates, kusanganisira kongiri, masonry, huni, uye mabhodhi ekudzivirira.
- Iyo inovimbisa kubatana kwakasimba pakati pedhaka uye substrate, kuderedza njodzi ye delamination nekuvandudza kusimba kwenguva refu.
2. Flexibility uye Crack Resistance:
- RDP inovandudza kuchinjika uye elasticity yedhaka, ichiibvumira kugarisa substrate kufamba uye kusiyanisa kwekushisa pasina kupaza.
- Inoderedza kuumbwa kwekupwanyika kweshrinkage panguva yekuomeswa nekurapa, zvichiita kuti igare yakasimba uye inogadzirisa dhaka.
3. Kuchengeta Mvura uye Kushanda:
- RDP inobatsira kudzora zviri mukati memvura mudhaka, kuvandudza kushanda, uye kuderedza kurasikirwa kwemvura panguva yekushandisa.
- Inosimudzira kupararira uye kuenderana kwedhaka, kuve nechokwadi chekufukidzwa kwakafanana uye kuderedza tsvina yezvinhu.
4. Kuwedzera Simba:
- RDP inokwidziridza ma mechanic zvimiro zvedhaka, kusanganisira kumanikidza simba, flexural simba, uye abrasion kuramba.
- Inobatsira kune simba rose uye kusimba kwedhaka, zvichiita kuti ive yakakodzera kune zvakasiyana-siyana zvekuvaka.
5. Kuisa Kudzora Nguva:
- RDP inobvumira kutonga kuri nani pamusoro penguva yekumisikidza yedhaka, ichigonesa zvigadziriso kuti zvienderane nezvinodiwa zvekushandisa.
- Inochengetedza nguva dzinoenderana uye dzinofanotaurwa dzekugadzirisa, kufambisa maitiro ekuvaka anoshanda.
6. Sag Resistance uye Shrinkage Reduction:
- RDP inobatsira kudzikisa kudonha kana kudonha kwedhaka panguva yekunyorera, kunyanya mukumisikidzwa kwakamira kana pamusoro.
- Inoderedza kuderera kwedhaka panguva yekuomeswa uye kurapa, zvichiita kuti pave nenzvimbo dzakapfava uye dzakafanana.
7. Kuenderana neZviwedzerwa:
- RDP inowirirana nehuwandu hwakawanda hwezvinowedzera zvinowanzoshandiswa mukugadzira dhaka, zvakadai seplasticizers, accelerators, uye air-entraining agents.
- Inobvumira kugadziridzwa kwezvivakwa zvedhaka kuti zvisangane nezvinodiwa zvekuita, senge yakawedzera kudzivirira kwemvura kana kunamira kwakagadziridzwa.
8. Kusiyana-siyana muMaapplication:
- RDP inokodzera kuumbwa kwakasiyana-siyana kwedhaka, kusanganisira mataira anonamira, renders, self-leveling compounds, grouts, kugadzirisa madhaka, uye kudzivirira mvura.
- Inopa kuita kwakasiyana-siyana mukugadzira, ichibvumira vagadziri kuti vagadzirise zvivakwa zvedhaka kuti zvienderane nezvinodiwa zveprojekiti uye mamiriro ezvakatipoteredza.
Mukupfupisa, re-dispersible emulsion powder (RDP) chinhu chinokosha chekuwedzera mumatope ekushandisa, inopa huwandu hwakawanda hwezvipo zvinosanganisira kunatsiridza kunamatira, kushanduka, kuchengetedza mvura, kuwedzera simba, kuisa nguva yekutonga, sag resistance, shrinkage kuderedza, kuenderana nekuwedzera. , uye kushandiswa kwakasiyana-siyana mumashandisirwo. Kushandiswa kwayo kunobatsira mukugadzirwa kwemhando yepamusoro, yakasimba, uye yakavimbika masisitimu edhaka muzvirongwa zvekuvaka.
