Redispersible latex poda, inozivikanwawo seredispersible polymer poda (RDP), ipolymer poda inogadzirwa nespray drying water-based latex.Inowanzoshandiswa sekuwedzera mune zvakasiyana-siyana zvekuvaka, kusanganisira dhaka.Kuwedzera redispersible latex poda kune madhaka kunopa akasiyana mabhenefiti, anosanganisira kunamira kwakagadziridzwa, kuchinjika, kuramba kwemvura uye kuita kwese.
A. Hunhu hweredispersible latex powder:
1.Polymer kuumbwa:
Redispersible latex powder inowanzoumbwa nemapolymers akasiyana-siyana, akadai sevinyl acetate-ethylene (VAE), vinyl acetate-ethylene carbonate (VeoVa), etc. Aya mapolymer anobatsira kuti hupfu hukwanise kupararira mumvura.
2. Saizi yechikamu:
Iyo particle size ye redispersible latex poda yakakosha pakupararira kwayo uye kushanda kwayo mumashandisirwo akasiyana siyana.Zvimedu zvakakamurwa zvakanaka zvinovimbisa kupararira kuri nyore mumvura kuita emulsions yakagadzikana.
3. Redispersibility:
Imwe yemhando huru yehupfu iyi ndeye redispersibility.Kana yasanganiswa nemvura, inoumba emulsion yakagadzikana yakafanana neyepakutanga latex, ichipa zvikomborero zvemvura latex mufomu yehupfu.
B.Basa redhispersible latex poda mudhaka:
1. Kuvandudza adhesion:
Kuwedzerwa kwehupfu inorasika mumatope kunowedzera kunamatira kune akasiyana ma substrates, anosanganisira kongiri, masonry uye ceramic mataira.Uku kunamatira kwakavandudzwa kunobatsira kuvandudza simba rose uye kusimba kwedhaka.
2. Wedzera kuchinjika:
Madhiri akagadziridzwa ane redispersible latex poda anoratidza kuchinjika kwepamusoro.Izvi zvinonyanya kubatsira mumamiriro ezvinhu apo substrate inogona kuona kufamba kuduku kana kuwedzera kwekushisa uye kuderera.
3. Isingapindi mvura:
Redispersible latex poda inopa dhaka remvura kuramba.Izvi zvakakosha mumashandisirwo apo dhaka rinoratidzwa kumvura kana hunyoro, senge mune zvekunze zvinoshandiswa kana nharaunda dzine hunyoro.
4. Deredza kutsemuka:
Iko kushanduka kunopiwa ne redispersible latex powder kunobatsira kuderedza mukana wekuputika kwedhaka.Izvi zvinonyanya kukosha mumashandisirwo apo kutsemuka kunogona kukanganisa kutendeseka kwechimiro.
5. Enhanced processability:
Madhaka ane redispersible latex powders anowanzo kuratidza kushanda kwakavandudzwa, zvichiita kuti zvive nyore kubata nekugadzira.Izvi zvingabatsira panguva yekuvaka.
6. Kuenderana nezvimwe zvinowedzera:
Redispersible latex powder inowirirana nezvimwe zvakasiyana-siyana zvekuwedzera zvinowanzoshandiswa mukugadzira dhaka.Uku kuita kwakasiyana-siyana kunobvumira kuita kwedhaka kuti kugadziriswe kune chaiwo mapurojekiti anodiwa.
C. Zvakanakira kushandisa redispersible latex poda mudhaka:
1. Kusiyana-siyana:
Redispersible latex poda inoshandiswa zvakanyanya uye inogona kushandiswa mumhando dzakasiyana dzemadhaka, anosanganisira akaonda-seti madhaka, anogadzirisa madhaka, uye madhaka asina mvura.
2. Wedzera kusimba:
Madhiri akagadziridzwa anopa kusimba kwakanyanya uye akakodzera kukumbira maapplication uko hupenyu hurefu hwakakosha.
3. Kuita kwakagadzikana:
Iyo inodzorwa yekugadzira nzira ye redispersible latex poda inova nechokwadi chekushanda kwakafanana, zvichikonzera mhedzisiro inofungidzira mukushandiswa kwedhaka.
4. Mutengo-kubudirira:
Nepo mutengo wekutanga we redispersible latex poda ungave wakakwira kupfuura zvechinyakare zvinowedzera, iyo inokwidziridzwa midziyo yainopa kune dhaka inogona kutungamirira kumari yekuchengetedza kwenguva refu nekuderedza kudiwa kwekugadzirisa nekugadzirisa.
5. Mafungiro ezvakatipoteredza:
Mvura-based dispersible latex powder inonyanya kushamwaridzana nemamiriro ekunze pane zvinogadziriswa-based-solvents.Vanobatsira pakugadzirisa maitiro ekuvaka.
Redispersible latex powder ndeyekuwedzera kwakakosha mukugadzirwa kwedhaka, inopa huwandu hwezvibatsiro zvakadai sekuvandudzwa kwekunamatira, kushanduka, kumira kwemvura uye kuderedza kuputika.Kuita kwayo kwakasiyana-siyana uye kuenderana nezvimwe zvinowedzera zvinoita kuti ive sarudzo yekutanga kune dzakasiyana siyana dzekuvaka.Nekusimudzira zvimiro zvedhaka, inorasika latex poda inobatsira kuvandudza kusimba kwese uye kushanda kwezvikamu zvekuvaka, zvichiita kuti ive chishandiso chakakosha mumaitiro emazuva ano ekuvaka.
