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.
